  Hereinafter, with reference to FIG. 3 and FIG. 4, elevator specification data 371, inspection history data 372, maintenance work history data 373, remote inspection history data 374, modulation history data 375, repair work history data 376, failure history data 377, The data structure of the operation history data 378 and the failure factor-specific data 379 will be described.

  The elevator specification data 371 has a data structure for storing the management number, model, date of manufacture, manufacturing number, name of the installed building, and maintenance contractor data of the elevator 20. The maintenance contractor of the elevator 20 is, for example, the name of a building owner or the name of a maintenance management company.

  The inspection history data 372 has a data structure for storing the management number of the elevator 20, the date and time of the inspection conducted by the engineer 350 at the site, inspection items, and inspection result data. The inspection includes, for example, inspection of the open / closed state of the doors 13 and 26 of the elevator 20 shown in FIG. 1, inspection of the stop position of each floor (inspection of the height deviation between the floor 12 and the floor 27 of the cage 22), wire 23 inspection, traveling speed inspection, and the like. In addition, whether or not an abnormality has been found as a result of the inspection, whether an abnormality has not been found but maintenance work such as cleaning is necessary, or parts need to be replaced soon are input as the inspection result. In FIG. 1, reference numeral 14 denotes a landing push button, reference numeral 28 denotes a destination floor button, and reference numeral 25 denotes a weight.

  The maintenance work history data 373 has a database structure for storing the management number of the elevator 20, the maintenance work date / time of the elevator 20 performed by the engineer 350 at the site, maintenance work items, and maintenance work results. The maintenance work items include, for example, inspection of the operation state of the elevator 20, cleaning of the door rail of the elevator 20, refueling to the driving device 24 shown in FIG. 1, adjustment of the brake of the elevator 20, and the like. The results of maintenance, cleaning, refueling, adjustment, etc. are entered in the maintenance work results.

  The remote inspection history data 374 has a data structure for storing a management number of the elevator 20, a remote inspection date, a remote inspection item, and a remote inspection result. The remote inspection of the elevator 20 is performed by the control panel 210 of the elevator 20 according to a preset schedule such as once a month, for example. The control panel 210 of the elevator 20 moves the cage 22 of the elevator 20 shown in FIG. 1 to a predetermined floor. During this movement, various sensors attached to the elevator 20 are checked for abnormalities in driving performance (acceleration, presence or absence of abnormal noise), door opening / closing, brakes, emergency batteries, external communication devices, and the like. The inspection result is stored in the remote inspection history data 374 from the information processing device 360 via the communication devices 250 and 320 and the communication network 30. The remote inspection may be performed according to an instruction from the remote monitoring center 310.

  The modulation history data 375 has a data structure for storing a management number of the elevator 20, a modulation occurrence date and time, a modulation item, and a modulation correspondence result. The modulation of the elevator 20 refers to a case where the result of the inspection, inspection, maintenance work or remote inspection by the engineer 350 does not reach the abnormal value but changes from the normal value of the elevator 20. . For example, as a result of checking the traveling speed, the value is within the allowable value, but when the previous check or when the deviation of the elevator 20 from the value of the previous check result is large, the modulation item Recorded as “traveling speed”.

  The repair work history data 376 has a data structure for storing a management number of the elevator 20, a repair work date, a repair work item, and a repair work result. The repair work is a restoration work by replacement of parts such as replacement of the wire 23, replacement of the hanger roller, replacement of the brake pad, replacement of the control board, and replacement of the relay. Therefore, the name of the replacement part such as “wire replacement”, “hanger roller replacement”, “brake pad replacement”, etc. is entered in the repair work item, and “repair work completed”, “re-repair” are entered in the repair work result column. Items such as “Necessary” are entered.

  The failure history data 377 has a data structure for storing the management number, failure occurrence date / time, failure code, failure site information, failure content, recovery method, and recovery determination result of the elevator 20. The failure code is a code output from the control panel 210 when a failure occurs in the elevator 20 or a combination of numbers and English letters. The types of failure codes are, for example, about 1000 types. The failure part information stores the name of the part where the failure has occurred, such as “Kagodo”. The failure content stores a failure state such as “cannot be opened” or “cannot be closed”. For example, when the engineer 350 is dispatched to perform inspection, inspection, and recovery, the restoration method item is input as “engineer dispatch”. Further, in the item of the recovery method, for example, when the remote recovery system 100 recovers, “Remote recovery” is input. In the item of the restoration determination result, when the elevator 20 is restored and the operation is resumed, “Recovery” is input. In addition, in the item of the restoration determination result, when the elevator 20 fails to be restored, “failure” is input.

  The operation history data 378 stores the date and time immediately before the occurrence of the failure and the operation state of each part of the elevator 20. For example, a certain operation date and time immediately before the failure, the position of the cage 22 at that time, the moving direction, the speed, the open / closed state of the doors 13 and 26, and the like are stored.

  The failure factor-specific data 379 includes the number of failure factors corresponding to the failure code as a result of inspection and inspection by the engineer 350 when a certain failure code is output from the control panel 210, and remote Stored is the total number of failure factors corresponding to the failure code when the recovery system 100 recovers. For example, when the failure code is 0001 indicating a failure related to the doors 13 and 26, the engineer 350 inspected the site, and as a result, the cause of the output of the failure code “0001” is the clogging of the door sill (failure factor 1). Or a contact failure of the switch of the door opening / closing device (failure factor 2), or other failure factor 3. Therefore, in the failure factor-specific data 379, when the failure code “0001” is output, there are 100 cases of the door sill clogging factor (failure factor 1), and the contact failure of the door opening / closing device switch (fault factor). The data structure is such that the number of cases 2) is 50 and the number of other failure factors 3 is 10, and the data is arranged in descending order. In the case of recovery by the remote recovery system 100, when the elevator 20 is successfully recovered by the recovery command, the number of failure factors corresponding to the failure code that is the basis of the recovery command is added to the total number of failure factors.

  Further, in the case of the failure code “0002”, the engineer 350 checks the site, and the cause of the failure code “0002” is that the control circuit in the control panel 210 is malfunctioning (failure factor 4). Or a malfunction of the CPU attached to the control board (fault factor 5) or other fault factor 6. In the case of the failure code “0002”, the failure factor-specific data 379 is 100 when the malfunction of the control circuit is a factor (failure factor 4) and 50 when the malfunction of the CPU is a factor (failure factor 5). The data structure is such that there are 10 cases of other failure factors 6, and the data is arranged in descending order of the number of cases.

  As shown in FIG. 5, the restoration diagnosis database 380 includes a restoration diagnosis instruction set that is a set of restoration instructions and restoration diagnosis instructions in descending order of the number of failure causes in the failure factor-specific data 379, and elevators by executing the restoration instructions. Stored is a recovery rate (%), which is the rate at which 20 failures have been recovered. The restoration diagnosis database 380 is a database in which the restoration diagnosis instruction set, the restoration rate, and the restoration operation classification are linked to the failure factor-specific data 379 described above.

  Hereinafter, the data configuration of the recovery diagnosis database 380 when the failure code indicated by reference numeral 381 in FIG. 5 is “0001” indicating a failure relating to the doors 13 and 26 will be described. If the door sill is clogged (Failure factor 1), the restoration diagnosis data will be “Failure factor 1”, “Door circuit reset + door high torque open / close” as the restoration command, and “Door open / close diagnostic” as the restoration diagnostic command. The data configuration is such that a recovery diagnosis command set A, which is a set of two commands, a recovery rate a% by a recovery operation by this recovery command, and a recovery operation classification “A” are linked. Here, the recovery operation classification is a classification of the recovery diagnosis command set depending on whether or not the movement of the elevator 20 is accompanied during the recovery operation as viewed from the outside. For example, as in the restoration diagnosis command set A, when the doors 13 and 26 are opened / closed during the restoration operation (“door high torque opening / closing”), the restoration operation classification is “A”. Further, the recovery operation classification of the recovery diagnosis command set that does not involve the operation of the elevator 20 when viewed from the outside during the recovery operation, such as control circuit reset and CPU reset described later, is “B”. If the contact failure of the door open / close device switch is the cause (failure factor 2), the restoration diagnosis data is “door circuit reset + door opening / retry retry” as the restoration command, and the restoration diagnosis command is “ The data structure is such that a recovery diagnosis command set B, which is a set of two commands for “door opening / closing diagnosis”, a recovery rate b% of a recovery operation by this recovery command, and a recovery operation classification “A” are linked. Similarly, in the case of the failure factor 3, the recovery diagnosis data has a data configuration in which the recovery diagnosis command set C, the recovery rate c%, and the recovery operation category “A” are linked to the number data of the failure factor 3. Yes. As described above, the recovery diagnosis database 380 includes a failure code, a failure factor corresponding to the failure code, the number of the failure factors, a recovery diagnosis command set that is a set of a recovery command and a recovery diagnosis, a recovery rate, and a recovery rate. It is stored in the database in association with the operation classification. In this embodiment, the recovery rate b% is a larger value than the recovery rates a% and c%, and the recovery diagnosis command set B has a higher recovery rate than the recovery diagnosis command set A and the recovery diagnosis command set C. ing.

  Next, the data structure of the recovery diagnosis database 380 when the failure code is “0002” indicating a failure related to the control circuit, indicated by reference numeral 382 in FIG. 5, will be described. In the case of a malfunction of the control circuit (failure factor 4), the recovery diagnosis data includes two commands: “control circuit reset” as the recovery command and “diagnosis on each floor” as the recovery diagnosis command. This is a data configuration in which a recovery diagnosis command set D, which is a set of the above, a recovery rate d% by a recovery operation based on the recovery diagnosis command, and a recovery operation classification “B” are linked. As described above, the recovery command of “control circuit reset” included in the recovery diagnosis command set D does not involve the operation of the elevator 20 when viewed from the outside during the recovery operation. “B” is stored in the category. In the case of a CPU malfunction (fault factor 5), the restoration diagnosis data is a set of two commands: “CPU reset” as a restoration command and “diagnosis on each floor” as a restoration diagnosis command. The recovery diagnosis command set E, the recovery rate e% by the recovery operation based on the recovery diagnosis command, and the recovery operation classification “B” are linked. Since the recovery command “CPU reset” does not accompany the operation of the elevator 20 when viewed from the outside during the recovery operation, “B” is stored in the recovery operation classification of the recovery diagnosis command set E. Similarly, in the case of the failure factor 6, the restoration diagnosis data has a data configuration in which the restoration diagnosis command set F, the restoration rate f%, and the restoration operation classification “B” are linked to the number data of the failure factor 6. Note that the recovery rate is highest in e% of the recovery diagnosis command set E.

  Next, the recovery operation condition database 390 will be described. As shown in FIG. 6, the restoration operation condition database 390 includes the elevator 20 management number, model, date of manufacture, installation building name, maintenance contractor data, etc., and the elevator 20 restoration operation. A condition schedule table 391 is stored.

  The operation condition schedule table 391 shown in FIG. 6 defines a remote recovery operation category in which execution is agreed with the customer for each day of the week and time zone of the elevator 20 with the management number “123456”. . The ○ mark in the table indicates that the remote recovery operation category has been agreed with the customer for execution, the X mark indicates that the execution has not been agreed with the customer, and △ The mark indicates that the customer has agreed to execute the recovery operation at the discretion of the customer.

  As shown in the operation condition schedule table 391 in FIG. 6, the elevator 20 having the management number “123456” is accompanied by the movement of the elevator 20 during the recovery operation from midnight to 6:00 in the early morning regardless of the day of the week. It has been agreed with the customer to execute both the remote recovery operation of the section “A” and the remote recovery operation of the section “B” that does not involve the movement of the elevator 20 during the recovery operation. Therefore, in this elevator 20, regardless of the day of the week, in the early morning, both the remote recovery operation of the category “A” and the remote recovery operation of the category “B” can be executed.

  In addition, as shown in the operation condition schedule table 391 in FIG. 6, the elevator 20 has a remote recovery operation of the category “A” accompanied by the movement of the elevator 20 during the recovery operation after 6 o'clock on Saturday and Sunday morning. Although no agreement has been made with the customer, it has been agreed with the customer that the remote restoration operation of the section “B” that does not involve the movement of the elevator 20 during the restoration operation is executed. Therefore, after 6 am on Saturdays and Sundays, the remote recovery operation of the category “A” cannot be executed, but the remote recovery operation of the category “B” can be executed.

  In addition, as shown in the operation condition schedule table 391 of FIG. 6, the elevator 20 performs the restoration operation of the classification “A” accompanied by the movement of the elevator 20 during the restoration operation after 6 o'clock in the morning on weekdays. As a result, an agreement with the customer has been made, and an agreement with the customer has been made regarding the execution of the remote recovery operation of category “B” that does not involve the movement of the elevator 20 during the recovery operation. Accordingly, after 6 am on Sunday morning, the recovery operation of the category “A” can be executed by the customer, and the category “B” can be executed remotely.

  The recovery operation condition database 390 shown in FIG. 7 is a remote operation in which execution is agreed with the customer for each time zone of the specific day of the elevator 20 with the management number “123456” described above with reference to FIG. It includes an operation condition schedule table 393 indicating restoration operation classification. As shown in the operation condition schedule table 393 in FIG. 7, on the specific day, the remote recovery operation of the category “A” and the category “B” has been agreed with the customer regardless of the time zone. The remote recovery operation of the category can also be executed.

  The restoration operation condition database 390 shown in FIG. 8 is stored between the customer for each day of the week and the time zone of the elevator 20 having the management number “78990” different from the management number “123456” described with reference to FIGS. It includes an operation condition schedule table 395 indicating remote recovery operation categories for which execution has been agreed. As shown in the operation condition schedule table 395 in FIG. 8, the elevator 20 has a remote recovery operation of the category “A” accompanied by the movement of the elevator 20 during the recovery operation after 6 o'clock in the morning on weekdays. Although an agreement has not been made, it has been agreed with the customer to execute the remote restoration operation of category “B” that does not involve the movement of the elevator 20 during the restoration operation. Therefore, after 6 am on weekdays, the remote recovery operation of the category “A” cannot be executed, but the remote recovery operation of the category “B” can be executed. In addition, after 6 o'clock on Saturday and Sunday morning, the recovery operation of the category “A” accompanied by the movement of the elevator 20 during the recovery operation has been agreed by the customer to be executed by the customer, and the recovery operation is in progress. In addition, it has been agreed with the customer that the remote recovery operation of the section “B” that does not involve the movement of the elevator 20 is executed. Accordingly, after 6 am on Saturdays and Sundays, the recovery operation of the category “A” can be executed by the customer, and the category “B” can be executed remotely.

  The recovery operation condition database 390 shown in FIG. 9 is a remote that has been agreed to be executed with a customer for each time zone of a specific day of the elevator 20 with the management number “789012” described above with reference to FIG. An operation condition schedule table 397 indicating the recovery operation classification is included. As shown in the operation condition schedule table 397 in FIG. 9, on the specific day, the remote recovery operation of the category “A” and the category “B” has not been agreed with the customer regardless of the time zone, None of the remote recovery operations can be performed.

  The recovery operation conditions described above are determined by the operation status of the customer's elevator 20 and the maintenance management status such as the presence / absence of a manager. For this reason, the remote recovery system 100 of the present embodiment includes a customer terminal 400 that communicates with the remote recovery device 300 via the communication network 37. The customer can access the recovery operation condition database 390 of the remote recovery device 300 through the customer terminal 400 and update or change the recovery operation conditions as needed according to the operation status and maintenance management status of the elevator 20.

  Hereinafter, the operation of the remote recovery system 100 when a failure signal is transmitted from the elevator 20 will be described with reference to FIGS. 2, 10, and 11. In the following description, the remote recovery operation when the failure code signal “0001” regarding the doors 13 and 26 is first transmitted will be described. Next, a remote recovery operation when a failure code “0002” related to a control circuit incorporated in the control panel 210 is transmitted will be described. The remote recovery system 100 can also cope with a case where a failure code related to a part other than the above is transmitted.

  2 and 10, the control panel 210 of the elevator 20 determines whether or not a failure has occurred in the elevator 20. When a failure relating to the doors 13 and 26 of the elevator 20, for example, a failure such as a door opening / closing failure, the control panel 210 displays a failure code “0001” indicating that the failure occurred and the failure is a failure relating to the door, The part information and the operation data immediately before the occurrence of the failure of the elevator 20 immediately before the occurrence of the failure are output to the communication device 250. If no failure occurs in the elevator 20, the control panel 210 returns to the beginning of step S <b> 101 and continues monitoring the elevator 20.

  When the failure code “0001”, the failure part information, and the operation data immediately before the occurrence of the failure are input from the control panel 210, the communication device 250 receives the failure code “0001”, the failure code as shown in step S102 of FIGS. The failure signal including the part information, the operation data immediately before the occurrence of the failure, the management number of the elevator 20 and the failure occurrence date and time is transmitted to the communication network 30. As shown in step S <b> 103 of FIG. 2 and FIG. 10, the communication device 320 of the remote monitoring center 310 receives a failure signal transmitted from the communication device 250 via the communication network 30. Upon receiving the failure signal, the communication device 320 sends the failure code “0001” included in the failure signal, the failure part information, the operation data immediately before the failure occurs, the management number of the elevator 20, and the failure occurrence date and time to the information processing device 360. Output. The information processing apparatus 360 stores the input failure code “0001”, the management number of the elevator 20, and the failure occurrence date / time in the failure history data 377 of the maintenance database 370. Further, the information processing device 360 stores the input operation data immediately before the occurrence of the failure in the operation history data 378.

  The information processing apparatus 360 proceeds to step S104 illustrated in FIG. 10 and selects a restoration command and a restoration diagnosis command corresponding to the failure code “0001”. As described above with reference to FIG. 5, the recovery diagnosis database 380 is a database in which a failure diagnosis data set 379 is linked to a recovery diagnosis command set, a recovery rate, and a recovery operation classification. Hereinafter, the data configuration of the recovery diagnosis database 380 when the failure code is “0001” indicating a failure relating to the doors 13 and 26 will be briefly described again. When the door sill is clogged (Failure factor 1), the restoration diagnosis data is “door circuit reset + door high-torque opening / closing” as the restoration command, and “door opening / closing” as the restoration diagnosis command. This is a data configuration in which a recovery diagnosis command set A, which is a set of two commands “diagnosis”, a recovery rate a% by a recovery operation by this recovery command, and a recovery operation classification “A” are linked. Similarly, when the contact failure of the door opening / closing device switch is the cause (failure factor 2), the restoration diagnosis data is “door circuit reset + door opening / retry retry” as the restoration command in the number of failure cause 2 data, restoration diagnosis. As a command, a data configuration is obtained by linking a recovery diagnosis command set B, which is a set of two commands of “door opening / closing diagnosis”, and a recovery operation recovery rate b% by this recovery command and a recovery operation classification “A”. Yes. Similarly, in the case of failure factor 3, the recovery diagnosis data has a data configuration in which the recovery diagnosis command set C, the recovery rate c%, and the recovery operation category “A” are linked to the number of failures factor 3 data. Further, as described above, the recovery rate a% is larger than the recovery rates b% and c%, and the recovery diagnosis command set B has a recovery rate higher than that of the recovery diagnosis command set A and the recovery diagnosis command set C. It is high.

  The information processing device 360 may select, as a recovery command, a command corresponding to the failure factor having the largest number of cases among the plurality of failure factors corresponding to the failure code “0001”. Further, the information processing apparatus 360 may select a command having the highest recovery rate among a plurality of commands corresponding to the failure code “0001” as a recovery command. Then, the information processing device 360 selects a restoration diagnosis command set that is set together with the restoration command selected by the restoration diagnosis command corresponding to the selected restoration command.

  First, a case will be described in which the information processing apparatus 360 selects a command corresponding to a failure factor having the largest number of cases among a plurality of failure factors corresponding to the failure code “0001” as a recovery command. The information processing apparatus 360 refers to the recovery diagnosis database 380 and confirms the failure factor having the largest number of cases when the failure code is “0001” as the recovery instruction. Then, the information processing apparatus 360 performs a restoration operation for executing a restoration operation corresponding to the garbage clogging of the door sill (fault factor 1) which is the most frequent failure factor, “door circuit reset + door high torque opening / closing”, A restoration diagnosis command set A including two “door opening / closing diagnosis” which is a restoration diagnosis command for executing a restoration diagnosis operation corresponding to the result of the restoration operation is selected.

  Next, a case where the information processing apparatus 360 selects a command having the highest recovery rate among a plurality of commands corresponding to the failure code “0001” as a recovery command will be described. The information processing apparatus 360 refers to the recovery diagnosis database 380 and confirms the recovery rate with the highest recovery rate corresponding to the failure code “0001” as the recovery command. Then, the information processing device 360 is configured to execute a recovery operation corresponding to the factor (failure factor 2) caused by the contact failure of the switch having the highest recovery rate b% “door circuit reset + door opening / closing retry”, A restoration diagnosis command set B including two “door opening / closing diagnosis” which is a restoration diagnosis command for executing a restoration diagnosis operation corresponding to the result of the restoration operation is selected.

  When selecting a recovery diagnosis command set, the selection of whether to be based on the most frequent failure factor corresponding to the failure code “0001” or based on the recovery rate of the recovery diagnosis command set corresponding to the failure code “0001” is as follows: You may do as follows. For example, of the ratio of the maximum number of cases to the next number of cases (number of cases ratio) and the ratio of the maximum recovery rate and the next recovery rate (recovery rate ratio), You may select the one where the maximum value protrudes. Further, for example, if the previous remote recovery has failed, a different selection method may be used. Further, the selection of the restoration diagnosis command set may be determined by, for example, the model and specification of the elevator 20.

  In the following description, a case will be described in which the information processing apparatus 360 selects the restoration diagnosis instruction set A based on the failure factor 1 having the largest number corresponding to the failure code “0001”.

  When the restoration diagnosis command set A is selected in step S104 in FIG. 10, the information processing apparatus 360 proceeds to step S105 in FIG. 10 and determines whether or not a remote restoration operation can be performed using the selected restoration diagnosis command set. To do.

  The information processing apparatus 360 searches the operation condition schedule tables 391, 393, 395, and 397 corresponding to the elevator 20 in which the failure has occurred with reference to the recovery operation condition database 390 shown in FIGS. When the input failure occurrence date falls on the day specified in the normal weekly schedule, refer to the normal operation condition schedule tables 391 and 395 as shown in FIGS. It is determined whether or not the restoration diagnosis command set selected in step S104 of FIG. 10 can be executed.

  As an example, a case will be described in which the elevator 20 in which a malfunctioning device has occurred is the elevator 20 to which the recovery operation condition database 390 defined in FIG. 6 is applied and the remote recovery operation is scheduled to be executed at 9:00 am on Sunday. . In this case, the recovery diagnosis command set corresponding to the recovery operation category “A” cannot be remotely executed from the operation condition schedule table 391 defined in FIG. 6, and the recovery diagnosis command set corresponding to the recovery operation category “B”. It can only be executed remotely. For this reason, the information processing apparatus 360 determines that the recovery diagnosis command set A whose recovery operation classification is “A” cannot be executed remotely, and proceeds to step S125 of FIG.

  In step S125 of FIG. 10, the information processing apparatus 360 determines whether or not the recovery diagnosis command set A can be executed by customer operation at 9:00 am on Sunday when the execution of the remote recovery operation is scheduled. As shown in the operation condition schedule table 391 in FIG. 6, since there is no Δ mark indicating that the execution of the recovery operation by the customer has been agreed at this date and time, the information processing apparatus 360 performs step S125 in FIG. 10. It determines with NO and progresses to step S130 of FIG. Then, the information processing apparatus 360 outputs a notification that remote recovery is not possible to the remote monitoring center 310.

  The notification that remote recovery is not possible, which is output from the information processing device 360 to the remote monitoring center 310, is displayed on the display 331 of the remote monitoring center 310 as shown in FIG. After confirming this display, the supervisor 334 causes the elevator 20 to stop operating and announce as shown in step S131 of FIG. 2 and FIG. Then, the supervisor 334 instructs the service center 340 in the vicinity of the building 10 to dispatch the engineer 350 to the building 10 through the telephone 333 as shown in step S132 of FIGS.

  On the other hand, when the remote recovery operation is scheduled to be executed at 5:00 in the early morning of Sunday, the recovery diagnosis command set and the recovery operation category corresponding to the recovery operation category “A” from the operation condition schedule table 391 defined in FIG. Both the restoration diagnosis command sets corresponding to “B” can be executed remotely. For this reason, the information processing apparatus 360 determines that the recovery diagnosis command set A whose recovery operation classification is “A” can be executed remotely.

  When the execution of the remote recovery operation is scheduled on a specific day shown in FIG. 7, the recovery diagnosis instruction set corresponding to the recovery operation category “A”, the recovery operation category “ The recovery diagnosis command set corresponding to “B” can be executed remotely. For this reason, the information processing apparatus 360 determines that the recovery diagnosis command set A whose recovery operation classification is “A” can be executed remotely.

  Next, as illustrated in FIGS. 2 and 3, the information processing device 360 acquires the model, manufacturing date, and manufacturing number of the elevator 20 from the elevator specification data 371 using the management number of the elevator 20. Based on the acquired specification data, the information processing device 360 confirms whether the elevator 20 has a specification that allows a recovery operation and a recovery diagnosis operation based on a recovery command and a recovery diagnosis command from the remote recovery device 300. If the elevator 20 is a model incapable of remote recovery operation, the information processing apparatus 360 proceeds to step S125 in FIG.

Further, as shown in FIG. 2, the information processing apparatus 360 refers to inspection history data 372, maintenance work history data 373, remote inspection history data 374, modulation history data 375, repair work history data 376, and failure history data 377. Then, the following (a) to (f) are confirmed.
(A) The elevator 20 has been instructed to re-adjust in a recent inspection.
(B) The elevator 20 has a maintenance plan recently or on the day, and the possibility of misadjustment is predicted.
(C) There was an abnormality diagnosis result in the elevator 20 by remote inspection.
(D) Recently, the elevator 20 has been modulated.
(E) The elevator 20 has recently been repaired.
(F) The elevator 20 has recently transmitted a failure signal with a similar failure code.

  If any one or more of the above (a) to (f) is applicable, the information processing apparatus 360 restores the restoration by the customer operation or the engineer 350 to the building 10 rather than the remote recovery by the remote recovery system 100. It is determined that it is better to be dispatched, and NO is determined in step S105 of FIG. Then, the information processing apparatus 360 proceeds to step S125 in FIG.

On the other hand, in step S105 shown in FIG. 10, the information processing apparatus 360, as shown in FIG. 2, the inspection history data 372, maintenance work history data 373, remote inspection history data 374, modulation history data 375, repair work history data 376. The following (g) to (m) are confirmed with reference to the failure history data 377.
(G) It is a specification that allows the elevator 20 to perform a recovery operation and a recovery diagnosis operation by a recovery command and a recovery diagnosis command from the remote recovery device 300.
(H) The elevator 20 has not been instructed to re-adjust in a recent inspection.
(I) The elevator 20 has no maintenance plan recently or on the day, and the possibility of misadjustment is not predicted.
(J) There is no abnormality diagnosis result in the elevator 20 by remote inspection.
(K) Recently, there is no modulation in the elevator 20.
(L) The elevator 20 has not been repaired recently.
(M) The elevator 20 has not recently transmitted a failure signal with a similar failure code.

  When all the requirements (g) to (m) are satisfied and the recovery operation command set A can be remotely recovered with reference to the recovery operation condition database 390, the information processing device 360 is configured as shown in FIG. YES is determined in step S105 shown, and the process proceeds to step S106 in FIG. 10 to determine the recovery diagnosis command set used for remote recovery as the recovery diagnosis command set A.

  Then, the information processing apparatus 360 proceeds to step S107 and notifies the remote monitoring center 310 of the start of remote recovery. This signal is displayed on the display 331 of the remote monitoring center 310. As a result, the supervisor 334 of the remote monitoring center 310 is notified that the remote recovery of the elevator 20 is started.

  The information processing apparatus 360 proceeds to step S108 in FIG. 10 and transmits the determined restoration diagnosis command set A from the communication apparatus 320. As shown in step S <b> 109 of FIG. 2 and FIG. 10, when receiving the recovery diagnosis command set A from the communication device 320, the communication device 250 outputs the recovery command and the recovery diagnosis command to the control panel 210.

  First, as shown in step S <b> 110 of FIG. 10, the control panel 210 determines whether the elevator 20 is stopped, the weight sensor of the cage 22, the camera in the cage 22, the output of the person sensor in the cage 22, etc. Make sure there are no passengers inside. When the control panel 210 confirms that the elevator 20 is stopped and that there are no passengers in the basket 22, the control panel 210 "starts remote recovery from now on" from the speaker of the communication device installed in the basket 22. The elevator door will open and close. "

  When the announcement ends, the control panel 210 proceeds to step S111 in FIG. 10 and executes a recovery operation according to the recovery command. Since the received restoration command is “door circuit reset + door high torque opening / closing” which is a restoration command for executing a restoration operation corresponding to the garbage clogging of the door sill (fault factor 1), the control panel 210 First, the door circuit of the control panel 210 is reset. This operation resets the state in which the door circuit cannot open or close the door 13 or the door 26 and detects the open (or closed) state or the half-open (or half-closed) state, and opens or closes the door 13 or the door 26. This is a possible operation. Next, the control panel 210 increases the torque of the drive motor for the door 13 and the door 26 by 20 to 30% from the normal value, and opens and closes the door 13 and the door 26 with a force larger than normal. This operation is an operation in which the garbage stuck in the door sill is moved from the sill and the opening / closing operation of the doors 13 and 26 is restored to the normal state. As shown in step S112 of FIG. 10, the control panel 210 restores the garbage stuck in the thresholds of the doors 13 and 26 to confirm whether the doors 13 and 26 have been opened and closed. “Door open / close diagnosis” which is a diagnosis command is executed. The control panel 210 opens and closes the door 13 and the door 26 with a normal torque, and can the opening and closing operation be performed within a predetermined opening / closing time, or whether the current of the drive motor for the door 13 and the door 26 is larger than usual. Confirm. Next, the control panel 210 opens and closes the door 13 and the door 26 by reducing the torque of the drive motor by about 20% from the normal state, and checks whether there is any abnormality in the opening and closing time.

  When the control panel 210 determines that the doors 13 and 26 have been restored to the normal state by the restoration diagnosis operation, as shown in step S113 of FIG. 10, the control panel 210 proceeds to step S114 of FIG. In step S114, the control panel 210 outputs a determination result signal that the elevator 20 has been restored. This signal is transmitted from the communication device 250 to the communication network 30. The transmitted determination result signal is received by the communication device 320 as shown in step S115 of FIG. 11, and the determination result is input to the information processing device 360. Further, as shown in step S116 of FIG. 11, the determination result is notified from the information processing apparatus 360 to the remote monitoring center 310, and the result is displayed on the display 331 of the remote monitoring center 310. When the monitor 334 of the remote monitoring center 310 confirms this display, as shown in step S117 of FIG. 11, the operation of the elevator 20 is resumed and an announcement operation is performed. Further, the information processing apparatus 360 updates the maintenance database 370 and the recovery diagnosis database 380 as shown in step S118 and step S119 of FIG.

  On the other hand, if the result of the recovery diagnosis operation is NO in step S113 of FIG. 10, the control panel 210 proceeds to step S120 of FIG. In step S120, the control panel 210 outputs a determination result signal that restoration of the elevator 20 has failed. This signal is transmitted from the communication device 250 to the communication network 30. The transmitted determination result signal is received by the communication device 320 as shown in step S <b> 121 of FIG. 11, and the determination result is input to the information processing device 360. Further, the determination result is notified from the information processing apparatus 360 to the remote monitoring center 310 as shown in step S121 of FIG. 11, and the result is displayed on the display 331 of the remote monitoring center 310. When the monitor 334 confirms the display, the supervisor 334 causes the elevator 20 to stop operating and announce as shown in step S123 of FIG. In addition, the supervisor 334 instructs the service center 340 near the building 10 to dispatch the engineer 350 to the building 10 by the telephone 333 as shown in step S124 of FIG. 2 and FIG. Further, the information processing apparatus 360 updates the maintenance database 370 and the recovery diagnosis database 380 as shown in step S118 and step S119 of FIG.

  When the determination signal that the elevator 20 has been restored as shown in step S114 of FIG. 10 is input, the information processing device 360 updates the maintenance database 370 as follows.

  When a determination signal indicating that the elevator 20 has been recovered as shown in step S114 of FIG. 10 is input, the information processing apparatus 360 displays “remote recovery” in the recovery method item of the failure history data 377, and the recovery determination result. Store “Recovery” in the item. As described above, when the communication device 320 receives the failure signal, the information processing device 360 maintains the failure code “0001” input from the communication device 320, the management number of the elevator 20, and the failure occurrence date and time. The failure history data 377 of the database 370 is stored. Accordingly, all items of the failure history data 377 are updated by storing the current recovery method and the recovery determination result.

  Further, in this remote recovery, the information processing apparatus 360 refers to the recovery diagnosis database 380 and clogs the door sill that is the most frequent failure factor (failure factor 1) when the failure code is “0001” as the recovery command. 2) of “door circuit reset + door open / retry retry” that is a recovery command for executing a recovery operation corresponding to (2)) and “door open / close diagnosis” that is a recovery diagnostic command for executing a recovery diagnostic operation corresponding to the result of this recovery operation. A recovery diagnosis command set A consisting of two is selected and a recovery operation and a recovery diagnosis operation are executed. Accordingly, when the elevator 20 is successfully restored, the number of failure codes “0001” and failure factor 1 (garbage clogs on the door sill) in the restoration diagnosis database 380 is increased by one, and the restoration rate corresponding to the number of successful restorations. To increase. Further, the information processing device 360 increases the number of failure factors 1 of the failure code “0001” in the failure factor-specific data 379 by one.

  On the other hand, the information processing apparatus 360 updates the maintenance database 370 and the restoration diagnosis database 380 as follows when the determination signal indicating that the restoration of the elevator 20 has failed as shown in step S120 of FIG. 10 is input. When the determination signal indicating that the restoration of the elevator 20 has failed as shown in step S120 of FIG. 10 is input, the information processing apparatus 360 sets “remote recovery” as the recovery method item of the failure history data 377, and the recovery determination. Store “failure” in the result item. Further, the number of cases of failure code “0001” and failure factor 1 (garbage on the door sill) in the restoration diagnosis database 380 is left as it is, and the restoration rate is lowered by the amount of restoration failure. Note that if the recovery fails, the number of failure factors 1 of the failure code “0001” in the failure factor-specific data 379 is not changed.

  In the above description, a case has been described in which the information processing apparatus 360 selects the restoration diagnosis instruction set A based on the failure factor having the largest number corresponding to the failure code “0001”. When the information processing device 360 selects the recovery diagnosis command set B based on the recovery rate of the recovery diagnosis command set corresponding to the failure code “0001”, the normal operation is performed instead of the recovery operation of “door high torque opening / closing”. A difference is that a recovery operation of “door opening / closing retry” in which the opening / closing operation of the doors 13 and 26 is performed again by torque is performed. Other operations are the same as when the restoration diagnosis command set A is selected.

  If the remote recovery of the elevator 20 is successful, the number of door cloggings (failure factor 1), which has been the most frequent failure factor in the case of the failure code “0001”, increases. For this reason, when the remote recovery system 100 selects a recovery diagnosis command set based on the most frequent failure factor corresponding to the failure code “0001”, the failure code “0001” is input at the time of the next remote recovery. At this time, the information processing apparatus 360 selects the restoration diagnosis command set A again. When the recovery rate of the recovery diagnosis command set A is higher than the recovery rate of the recovery diagnosis command set B, the information processing apparatus 360 has a recovery rate of a plurality of commands corresponding to the failure code “0001”. Even when the highest command is selected as the return command, the restoration diagnosis command set A is selected.

  On the other hand, if the remote recovery of the elevator 20 fails, the number of failure factors 1 of the failure code “0001” in the failure factor-specific data 379 is not changed, but the recovery rate of the recovery diagnosis command set A is lowered. Thereby, the recovery rate of the recovery diagnosis command set B becomes relatively high. That is, the recovery rate ratio of the recovery diagnosis command set B to the recovery diagnosis command set A is increased. When the restoration rate ratio becomes larger than the number ratio calculated as the ratio of the number of failure factors 1 to the number of failures 2, the information processing apparatus 360 recovers among the plurality of commands corresponding to the failure code “0001”. The command with the highest rate is selected as the return command. For this reason, the information processing apparatus 360 selects the restoration diagnosis command set B having the highest restoration rate when the failure code “0001” is input at the time of the next remote restoration. Further, when the information processing device 360 does not select the restoration diagnosis command set A that has failed to be restored in the previous remote restoration, the failure factor 1 is linked to the failure factor 2 having the largest number corresponding to the failure code “0001”. Restored diagnosis command set B is selected.

  Further, when the information processing apparatus 360 selects the restoration diagnosis command set B having the highest restoration rate among the plurality of instructions corresponding to the failure code “0001” and succeeds in the restoration of the elevator 20, the restoration diagnosis instruction set The recovery rate of B increases. Therefore, in the next remote recovery, the information processing apparatus 360 selects the recovery diagnosis command set B as in the previous time. On the other hand, if the restoration diagnosis command set B fails to restore the elevator 20, the restoration rate of the restoration diagnosis command set B is lowered. When the recovery rate of the recovery diagnosis command set B is lower than the recovery rate of the recovery diagnosis command set A, the information processing device 360 selects the recovery diagnosis command set A. If the information processing device 360 does not select the recovery diagnosis command set B that has failed to recover in the previous remote recovery, the recovery diagnosis with the high recovery rate corresponding to the failure code “0001” next to the recovery diagnosis command set B Select command set A.

  Thus, when the remote recovery is successful, the remote recovery system 100 increases the number of failure factors and the recovery rate of the selected recovery diagnosis command set. In addition, if the remote recovery system 100 fails, the remote recovery system 100 reduces the recovery rate of the selected recovery diagnosis command set without changing the number of failure factors. For this reason, if the remote recovery is successful, there is a high possibility that the recovery diagnosis command set selected in the remote recovery is selected in the next remote recovery. Further, if the remote recovery fails, the possibility that the recovery diagnosis command set selected by the remote recovery is selected at the next remote recovery is reduced. For this reason, as the number of remote restorations increases, the information processing apparatus 360 can select a restoration diagnosis command set having a high possibility of restoration corresponding to the failure code from the restoration diagnosis database 380, and the restoration of the elevator 20 is ensured. Can be improved.

  Further, the information processing apparatus 360 selects the restoration diagnosis command set A in step S104 of FIG. 10, and when the scheduled execution date and time of the remote restoration operation is daytime on weekdays, it is determined as NO in step S105 of FIG. The process proceeds to step S125, and YES is determined in step S125 of FIG.

  In this case, the information processing apparatus 360 transmits the restoration diagnosis command set A to the control panel 210 via the communication apparatuses 320 and 250 as shown in step S126 of FIG. Then, as shown in step S127 of FIG. 10, the information processing device 360 transmits the restoration diagnosis command set A to the customer to the control panel 210 and operates the destination floor button 28 that is an input device of the elevator 20 on the local operation. Notify switching to mode. Thereafter, as shown in step S128 of FIG. 10, the information processing device 360 outputs a command to switch the destination floor button 28 that is the input device of the elevator 20 to the local operation mode. The control panel 210 keeps the memory stored without executing the contents of the recovery command and the recovery diagnostic command included in the recovery diagnostic command set A, and changes the destination floor button 28 to the local execution mode. Thereby, by pressing the destination floor button 28 in a specific manner, the execution of the recovery command and the recovery diagnosis command can be started.

  In step S129 in FIG. 10, the information processing apparatus 360 waits until the destination floor button 28 is pressed in a specific manner by a local maintenance manager or the like, and the restoration instruction and the restoration diagnosis instruction are executed. Then, when the recovery command and the recovery diagnosis command are executed, the recovery operation is terminated.

  When the destination floor button 28 is pressed in a specific manner within a predetermined time and the recovery command and the recovery diagnosis command are not executed, the information processing device 360 determines NO in step S129 of FIG. The process proceeds to step S130. Then, the information processing apparatus 360 outputs a notification that remote recovery is not possible to the remote monitoring center 310.

  The notification that remote recovery is not possible, which is output from the information processing device 360 to the remote monitoring center 310, is displayed on the display 331 of the remote monitoring center 310 as shown in FIG. After confirming this display, the supervisor 334 causes the elevator 20 to stop operating and announce as shown in step S131 of FIG. 2 and FIG. Then, the supervisor 334 instructs the service center 340 in the vicinity of the building 10 to dispatch the engineer 350 to the building 10 through the telephone 333 as shown in step S132 of FIGS.

  Next, a remote recovery operation when a failure code “0002” related to a control circuit incorporated in the control panel 210 is transmitted will be described. The description of the operation similar to the remote recovery operation when the failure code “0001” described above is transmitted will be omitted.

  As described above with reference to reference numeral 382 in FIG. 5, in the case of the failure code “0002”, the recovery diagnosis command set D, the recovery diagnosis command set E, and the recovery diagnosis command set stored in the recovery diagnosis database 380. F is a category “B” that does not involve the movement of the elevator 20 during the recovery operation. Therefore, as shown in FIGS. 6 and 7, in the case of the elevator 20 having the management number “123456”, it is possible to always perform the remote recovery operation. Therefore, when the restoration diagnosis command set D to F is selected in the elevator 20 with the management number “123456”, it is determined YES in step S105 in FIG. 10 and the remote restoration operation after step S106 in FIG. 10 is performed. Executed.

  On the other hand, as shown in FIG. 9, in the case of the elevator 20 with the management number “789012”, it is impossible to execute any remote recovery operation on a specific day. Therefore, the elevator 20 having the management number “789012” cannot perform remote recovery on a specific day. Also. The recovery operation cannot be executed by the customer on a specific date. For this reason, the information processing apparatus 360 determines NO in both steps S105 and S125 in FIG. 10, proceeds to step S130 in FIG. 11, stops the operation of the elevator 20, and notifies the remote monitoring center 310 to that effect.

  The remote recovery operation is the same as in the case of the failure code “0001” described above.

  The remote recovery system 100 according to the embodiment described above can recover from a failure of the elevator 20 based on the customer's elevator operation circumstances.

  Further, the remote recovery system 100 causes the elevator 20 to execute a recovery operation and a recovery diagnosis operation in response to a command from the remote recovery device 300 arranged at a location away from the elevator 20 when various failures occur in the elevator 20. Thus, the elevator 20 can be restored. For this reason, when failure occurs in the elevator 20, the elevator 20 can be restored in a short time without dispatching the technician 350 to the site, and the operation service of the elevator 20 can be improved.

  Further, the remote recovery system 100 can select a failure history data 377, failure factor-specific data 379, so that a recovery diagnosis command set having a high recovery possibility can be selected in the next remote recovery based on the recovery determination result. The recovery diagnosis database 380 is updated. Therefore, as the number of remote restorations increases, the information processing apparatus 360 can select a more appropriate restoration diagnosis command set corresponding to the failure code from the restoration diagnosis database 380. Thereby, the restoration of the elevator 20 can be reliably performed, and the time required for the restoration can be shortened to improve the operation service of the elevator 20.

  As described above, in the embodiment described above, the recovery operation category is “A” for the operation accompanied by the movement of the elevator 20 during the recovery operation as viewed from the outside, and the operation of the elevator 20 as viewed from the outside during the recovery operation. Although it has been described that the recovery operation category “B” is not accompanied, the recovery operation category is not limited to such a category. For example, when the doors 13 and 26 are opened and closed during the recovery operation as viewed from the outside. The recovery operation may be classified according to the presence or absence of the operation of a specific part, such as those that do not involve the opening / closing operation of the doors 13 and 26.

  The present invention is not limited to the embodiments described above, but includes all changes and modifications that do not depart from the technical scope or essence of the present invention defined by the claims. .
