Elevator breakdown remote recovery system

The present invention relates to a system for performing remote recovery when a failure occurs in an elevator.

Conventionally, a communication terminal that is connected to a control panel that controls the driving of an elevator and transmits a failure signal including an error code when the elevator fails, and a failure history corresponding to the error code by receiving a failure signal transmitted from the communication terminal. Provides a monitoring center that retrieves data and transmits it to a portable terminal owned by the maintenance personnel, and supports the failure recovery of elevators that interprets the error codes received from the monitoring center by the mobile terminal of the maintenance personnel and displays them as recovery contents for each failure A system is known (see, for example, Patent Document 1). In the failure recovery support system described in Patent Document 1, the maintenance personnel can know the details of the elevator failure before arriving at the elevator where the failure occurred, and the repair work can be carried out immediately after arriving at the building. Make it possible.

In addition, there are cases in which an abnormality occurs in the elevator system due to temporary factors such as noise, and the operation of the elevator is stopped. However, when the occurrence of an abnormality is due to a temporary factor such as noise, after stopping the elevator, the cause of the abnormality disappears, and the abnormality of the elevator may not be detected. Therefore, when an abnormality is detected in the elevator system, the operation of the elevator is stopped, and after that, when the abnormality is not detected, a method of restarting the operation of the elevator has been proposed (for example, see Patent Document 2). ).

As shown in Fig. 2, in the maintenance database 370, elevator specification data 371, inspection history data 372, maintenance work history data 373, remote inspection history data 374, and modulation history data 375 , Repair work history data 376, failure history data 377, and failure factor data 378 are stored.

Hereinafter, referring to FIG. 3, 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), the failure history data 377, and the data structure of the failure factor data 378 will be described.

The elevator specification data 371 has a data structure for storing data of the control number, model, manufacturing date, serial number, name of the installation building, and usage of the installation building of the elevator 20. The use of the installation building is, for example, an office, a general residence, a restaurant, a school, and the like.

The inspection history data 372 has a data structure for storing data of the management number of the elevator 20, the date and time of the inspection conducted by the technician 350 locally, inspection items, and inspection results. The inspection column is, for example, inspection of the open/closed state of the doors 13 and 26 of the elevator 20 shown in Fig. 1, and inspection of the stop position of each floor (floor 12 and floor of car 22 ( 27), an inspection of the wire 23, an inspection of a running speed, and the like. In addition, as a result of the inspection, whether or not an abnormality was found as a result of the inspection, an abnormality was not found, but maintenance work such as cleaning is required, or parts replacement is required soon. In addition, in Fig. 1, 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 and time, maintenance work items, and maintenance work results of the elevator 20 performed by the technician 350 on site. Maintenance work items include, for example, confirmation of the operating state of the elevator 20, cleaning of the door rail of the elevator 20, oil supply to the drive device 24 shown in Fig. 1, adjustment of the brake of the elevator 20, etc. to be. In the maintenance work result, the results of inspection, cleaning, refueling, adjustment, etc. are input.

The remote inspection history data 374 has a data structure for storing a management number of the elevator 20, a remote inspection date and time, 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 car 22 of the elevator 20 shown in FIG. 1 to a predetermined floor. During this movement, various sensors mounted on the elevator 20 check whether there is any abnormality in the operation performance (acceleration, presence or absence of abnormal noise), door opening and closing, brakes, emergency batteries, and external contact devices. The inspection result is stored in the remote inspection history data 374 from the information processing device 360 through the communication devices 250 and 320 and the communication network 30. Further, the remote inspection may be performed in response 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 response result. The modulation of the elevator 20 refers to a case in which the result of inspection, inspection, maintenance work, or remote inspection by the technician 350 does not reach an abnormal value, but is changed from the normal value of the elevator 20 . For example, as a result of the inspection of the running speed, it is within the allowable value, but when the difference from the value of the inspection result up to the present of the elevator 20 or the previous inspection is large, in the modulation item, " Driving speed”.

The repair construction history data 376 has a data structure storing the management number of the elevator 20, the repair construction date and time, the repair construction item, and the repair construction result. The repair work is a repair work by replacement of parts such as replacement of the wire 23, replacement of a hanger roller, replacement of a brake pad, replacement of a control board, and replacement of a relay. Therefore, in the item of repair work, ``wire replacement'', ``hanger roller Names of replacement parts such as "replacement" and "brake pad replacement" are input, and items such as "repair work end" and "repair required" are input in the column of the repair work result.

The failure history data 377 has a data structure for storing the management number of the elevator 20, the date and time of failure, a failure code, a restoration method, and a restoration determination result. The failure code is a code that is output from the control panel 210 when a failure occurs in the elevator 20 or a combination of numbers and English characters. The types of fault codes are, for example, about 1000 types. In the item of the restoration method, for example, when the technician 350 is dispatched to perform inspection, inspection, and restoration, it is input such as "engineer dispatch". In addition, in the case of restoration by the remote restoration system 100, for example, the item of the restoration method is input as "remote restoration". In the item of the restoration determination result, when the elevator 20 is restored and the operation is resumed, it is input as "recovery". In addition, when the elevator 20 fails to recover, the item of the recovery determination result is input as "failure".

The data 378 for each failure factor is the number of failure factors corresponding to the failure code based on the result of the inspection and inspection by the technician 350 dispatching to the site when a failure code is output from the control panel 210, and, When the remote recovery system 100 recovers, the total number of the number of failure factors corresponding to the failure code is stored. For example, if the failure code is 0001 indicating a failure with respect to the doors 13 and 26, as a result of local inspection by the technician 350, the cause of the output of the failure code “0001” is the accumulation of garbage on the door sill ( Failure factor 1), contact failure of the switch of the door opening/closing device (failure factor 2), or other failure factor 3. Therefore, in the case of the failure factor data, when the failure code "0001" is output, 100 cases are the cause of garbage accumulation on the door sill (failure factor 1), and the contact failure of the switch of the door opening and closing device is the factor (failure factor 2) The data structure has the same data structure as 50 cases in the case of, and 10 cases in the case of 3 other failure factors, and the data is arranged so that the number of cases is increased. In the case of restoration by the remote restoration system 100, the number of failure factors corresponding to the failure code that was the basis of the restoration order when the elevator 20 is successfully restored by the restoration command Is added to

As shown in Fig. 4, the restoration diagnosis database 380 includes a set of restoration diagnosis commands, which are sets of restoration commands and restoration diagnosis commands, in the order of the number of failure factors of the data 378 for each failure factor, and the restoration command. The recovery rate (%), which is the rate at which the failure of the elevator 20 is recovered by the execution of, is stored. The recovery diagnostic database 380 is a database obtained by linking the recovery diagnostic command set and the recovery rate to the data 378 for each failure factor described above.

Hereinafter, the data configuration of the recovery diagnosis database 380 in the case where the fault code is "0001" indicating a fault with respect to the doors 13 and 26 will be described. When the accumulation of trash on the door sill is a factor (failure factor 1), the recovery diagnostic data is included in the number of failure factor 1 data as a recovery command ``door circuit reset + door high torque open/close'', and recovery diagnostic command is ``door A data structure in which a recovery diagnosis command set A, which is a set of two commands of “open/close diagnosis”, and a recovery rate x% by a recovery operation in accordance with this recovery command are linked. If the contact failure of the switch of the door opener is the cause (failure factor 2), the recovery diagnostic data is the number of failure factor 2 data, ``door circuit reset + door open/close retry'' as a recovery command, and ``door open/closed'' as a recovery diagnosis command A data structure in which the recovery diagnostic command set B, which is a set of two commands of "diagnosis", is linked with the recovery rate y% of the recovery operation by the recovery command. Similarly, in the case of the failure factor 3, the recovery diagnosis data has a data structure in which the recovery diagnosis command set C and the recovery rate z% are linked to the number of failure factors 3 data. In this way, the recovery diagnostic database 380 is a database by correlating a fault code, a fault factor corresponding to the fault code, the number of fault factors, a recovery diagnostic command set that is a set of recovery commands and recovery diagnostics, and a recovery rate. It was stored in. Further, in the present embodiment, the recovery rate y% is a value larger than the recovery rates x% and z%, 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.

Hereinafter, the operation of the remote recovery system 100 when a fault signal is transmitted from the elevator 20 will be described with reference to FIGS. 2 and 5 to 7. In the following description, the remote recovery operation when the fault code signal "0001" related to the doors 13 and 26 is initially transmitted is described. Next, a description will be given of a remote recovery operation when a failure code "0002" related to the brake in the drive device 24 is transmitted. In addition, the remote recovery system 100 can respond even when a failure code related to a part other than the above is transmitted.

2 and 5, the control panel 210 of the elevator 20 determines whether or not a failure has occurred in the elevator 20. In the event of a failure related to the doors 13 and 26 of the elevator 20, for example, a door opening/closing failure, the control panel 210 displays the date and time of the failure and a failure code indicating that the failure is a failure related to the door. "0001" is output to the communication device 250. When no failure occurs in the elevator 20, the control panel 210 returns to the beginning of step S101 and continues monitoring the elevator 20.

When the failure code "0001" is input from the control panel 210, the communication device 250, as shown in step S102 of Figs. 2 and 5, the failure code "0001" and the control number of the elevator 20, and the date and time of occurrence of the failure. A fault signal including a is transmitted to the communication network 30. As shown in step S103 of FIGS. 2 and 5, 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. When receiving the failure signal, the communication device 320 outputs the failure code "0001" included in the failure signal, the management number of the elevator 20, and the date and time of occurrence of the failure to the information processing apparatus 360. The information processing device 360 stores the inputted failure code "0001", the management number of the elevator 20, and the date and time of occurrence of the failure in failure history data 377 of the maintenance database 370.

Then, the information processing device 360 determines whether or not the elevator 20 in which the failure has occurred can be remotely restored, as shown in step S104 of FIG. 5. As shown in FIGS. 2 and 3, the information processing device 360 acquires the model, manufacturing date, and serial 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 checks whether the elevator 20 is a specification capable of a recovery operation or a recovery diagnosis operation according to a recovery command from the remote recovery device 300 or a recovery diagnosis command. When the elevator 20 is a model in which the restoration operation and the restoration diagnosis operation are not possible, the information processing device 360 determines NO in step S104 of FIG. 5. Then, the information processing device 360 outputs a notification that remote restoration is impossible to the remote monitoring center 310 as shown in step S127 in FIGS. 2 and 7.

In addition, the information processing device 360, as shown in Fig. 2, inspection history data 372, maintenance work history data 373, remote inspection history data 374, modulation history data 375, repair work history With reference to data 376 and failure history data 377, the following (a) to (f) are confirmed.

(a) The elevator 20 was instructed to adjust and fix in the recent inspection.

(b) There is a maintenance plan for the elevator 20 recently or on the same day, and the possibility of misadjustment is predicted.

(c) There was an abnormal diagnosis result in the elevator 20 due to remote inspection.

(d) Recently, there has been an occurrence of modulation in the elevator 20.

(e) The elevator 20 has recently undergone repair work.

(f) The elevator 20 recently transmitted a fault signal according to the same fault code "0001".

And, in the case of any one or more of the above (a) to (f), the information processing device 360 dispatches the technician 350 to the building 10 rather than the recovery by the remote recovery system 100. It judges that it is better, and it judges as NO in step S104 of FIG. Then, as shown in step S127 of FIGS. 2 and 7, the information processing device 360 outputs a notification that remote restoration is impossible to the remote monitoring center 310.

Further, the information processing device 360 uses the management number of the elevator 20 to determine from the elevator specification data 371 and the failure history data 377 whether the building 10 is a building with many false signals of failure. Confirm. In such a case, the information processing device 360 determines that it is better to dispatch the technician 350 to the building 10 than to recover by the remote recovery system 100, since there is a high possibility of erroneous transmission of a fault signal. , It is determined as NO in step S104 of FIG. 5. Then, the information processing device 360 outputs a notification that remote restoration is impossible to the remote monitoring center 310 as shown in step S127 in FIGS. 2 and 7.

A notification of the inability to recover remotely 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. Thereby, the monitor 334 of the remote monitoring center 310 is notified that the elevator 20 is not remotely restored. When the monitor 334 confirms this display, as shown in step S128 in Figs. 2 and 7, the monitor 334 makes an instruction of stopping the operation of the elevator 20 and an announcement operation. Then, the supervisor 334 dispatches the technician 350 to the building 10 to the service center 340 near the building 10 as shown in step S129 of FIGS. 2 and 7 by the telephone 333 Instruct them to do.

When it is determined in step S104 of FIG. 5 that the elevator 20 cannot be remotely restored, the information processing device 360 determines the input failure code "0001" in step S103, the control number of the elevator 20, and the failure. The occurrence date and time are stored in the failure history data 377 of the maintenance database 370. Then, the information processing device 360 terminates the remote recovery operation without updating other data of the maintenance database 370 and the recovery diagnosis database 380.

On the other hand, in step S104 shown in FIG. 5, as shown in FIG. 2, the information processing device 360, inspection history data 372, maintenance work history data 373, remote inspection history data 374, and modulation With reference to history data 375, repair work history data 376, and failure history data 377, the following (g) to (n) are confirmed.

(g) The elevator 20 is a specification that enables a recovery operation and a recovery diagnosis operation according to a recovery command and a recovery diagnosis command from the remote recovery device 300.

(h) Elevator 20 has not been instructed to correct the adjustment in the recent inspection.

(i) The possibility of misadjustment due to the lack of maintenance plans for the elevator 20 recently or on the day is not predicted.

(j) There is no abnormal diagnosis result in the elevator 20 by remote inspection.

(k) Recently, no modulation has occurred in the elevator 20.

(l) The elevator 20 has not been recently repaired.

(m) The elevator 20 has not recently sent a fault signal according to the same fault code "0001".

(n) Building (10) is not a building with many false signals.

And, when all the requirements (g) to (n) above are satisfied, the information processing device 360 determines YES in step S104 shown in FIG. 5, and remotely to the remote monitoring center 310 in step S105. Notify the start of restoration. This signal is displayed on the display 331 of the remote monitoring center 310. This notifies the monitor 334 of the remote monitoring center 310 that the remote restoration of the elevator 20 is started.

When the information processing device 360 notifies the remote monitoring center 310 of the start of remote restoration in step S105, the process proceeds to step S106 shown in FIG. 5 to issue a restoration instruction and a restoration diagnosis instruction corresponding to the failure code "0001". Choose. Previously, as described with reference to FIG. 4, the recovery diagnosis database 380 is a database in which the recovery diagnosis command set and the recovery rate are linked to the data 378 for each failure factor. Hereinafter, the data configuration of the recovery diagnosis database 380 in the case where the failure code is "0001" indicating a failure with respect to the doors 13 and 26 will be briefly described again. When the accumulation of trash on the door sill is a factor (failure factor 1), the recovery diagnostic data is the number of failure factor 1 data, ``door circuit reset + door high torque opening'' as a recovery command, and ``door opening/closing diagnosis'' as a recovery diagnostic command. A data structure in which the recovery diagnosis command set A, which is a set of two commands of "", and the recovery rate x% by the recovery operation by this recovery command are linked. Similarly, if the contact failure of the switch of the door opening/closing device is a factor (failure factor 2), the recovery diagnostic data is converted to the number of failure factor 2 data as a recovery command, ``door circuit reset + door open/close retry'', and a recovery diagnostic command. As an example, there is a data structure in which a recovery diagnosis command set B, which is a set of two commands of "door opening/closing diagnosis", is linked with a recovery rate y% of the recovery operation by this recovery command. Similarly, in the case of the failure factor 3, the recovery diagnosis data has a data structure in which the recovery diagnosis command set C and the recovery rate z% are linked to the number of failure factors 3 data. Further, as described above, the recovery rate y% is a value larger than the recovery rates x% and z%, 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.

The information processing device 360 may select, as a recovery command, an instruction corresponding to the failure factor with the largest number of failure factors among a plurality of failure factors corresponding to the failure code "0001". Further, the information processing device 360 may select, as the recovery command, the command having the highest recovery rate among a plurality of commands corresponding to the failure code "0001". Then, the information processing device 360 selects a recovery diagnostic command set in which the recovery diagnostic command corresponding to the selected recovery command is set with the selected recovery command.

A case in which the information processing device 360 selects a command corresponding to the failure factor with the largest number of failure factors corresponding to the failure code "0001" as the recovery command will be described. The information processing device 360 refers to the recovery diagnosis database 380 and checks the failure factor with the largest number of cases in the case of a failure code "0001" as a recovery command. In addition, the information processing device 360 includes a "door circuit reset + door high torque open/close" which is a recovery command for executing a recovery operation corresponding to the accumulation of garbage on the door sill (failure factor 1), which is the most frequent failure factor. A recovery diagnostic command set A consisting of two "door opening/closing diagnostics", which is a recovery diagnostic command for executing a recovery diagnostic operation corresponding to the result of the recovery operation, is selected.

Next, a description will be given of a case where the information processing device 360 selects, as a recovery command, a command having the highest recovery rate among a plurality of commands corresponding to the failure code "0001". The information processing device 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 a recovery command. Further, the information processing device 360 includes a "door circuit reset + door open/close retry", which is a recovery command for executing a recovery operation corresponding to the cause (failure factor 2) due to a defective contact of the switch having the highest recovery rate y%. A recovery diagnosis command set B consisting of 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 the recovery diagnosis command set, the selection of whether it is based on the failure factor with the largest number of cases corresponding to the failure code "0001" or the recovery rate of the recovery diagnosis command set corresponding to the failure code "0001" is as follows. You can do it together. For example, of the ratio between the maximum number of cases and the next number (the number of cases) and the ratio of the maximum recovery rate and the next recovery rate (recovery rate ratio), the side with a larger ratio, that is, the side where the maximum value protrudes from the next value. You can choose. Further, for example, in the case of failure in the previous remote recovery, a selection method different from the previous one may be taken. In addition, the selection of the restoration diagnosis command set may be determined by, for example, the model and specifications of the elevator 20.

In the following description, a case in which the information processing device 360 selects the recovery diagnosis command set A based on the failure factor 1 with the largest number corresponding to the failure code "0001" will be described.

When the restoration diagnosis command set A is selected in step S106 of FIG. 5, the information processing device 360 transmits the selected restoration diagnosis command set A from the communication device 320 as shown in step S107 of FIGS. 2 and 5. do. As shown in step S108 of FIGS. 2 and 5, when the communication device 250 receives the recovery diagnosis command set A from the communication device 320, it outputs the recovery command and the recovery diagnosis command to the control panel 210.

When the restoration command and the restoration diagnosis command are inputted, the control panel 210 performs a check operation as to whether the elevator 20 is in a state in which remote restoration can be started, as shown in step S109 of FIG. 5.

The control panel 210 checks whether there is a passenger in the car 22 from the output of the weight sensor of the car 22, a camera in the car 22, a person sensor, and the like. Further, the open/close state of the doors 13 and 26 is confirmed from the output of the camera in the car 22 and the door open/close sensor. In addition, the control panel 210 checks the presence or absence of a power outage.

When there are no passengers in the car 22 and the doors 13 and 26 are completely closed and not in a power outage state, the control panel 210 determines YES in step S109 of FIG. 5, and FIG. 5 It proceeds to step S110 of. Then, in step S110, the control panel 210, from the speaker of the telephone apparatus installed in the car 22, says, "Remote recovery is started from now on. The elevator door opens and closes.”

The control panel 210 determines NO in step S109 of FIG. 5 when there are passengers in the car 22, when the doors 13 and 26 are not completely closed, or when there is a power failure state, and FIG. The process proceeds to step S125 of 7 and the following preparation operation is performed.

First, the control panel 210 confirms that the floor 27 of the car 22 is at approximately the same level as the floor 12. After that, the control panel 210 opens the doors 13 and 26, and says, “Remote recovery starts. Please get off the elevator.”, etc., and an operation is performed to displace the passenger from the car 22. Or, the control panel 210 says, "Remote recovery starts. Please get off the elevator.” The door (13, 26) is opened and the passenger is dismounted from the car (22) while performing an announcement. In the control panel 210, when a passenger gets off the car 22 by such an operation, the doors 13 and 26 in the open state are completely closed. After that, the process proceeds to step S126 of FIG. 7 to determine whether there are any passengers in the car 22 in the same manner as described above, and whether the doors 13 and 26 are in a completely closed state. Make sure that the floor 27 is about the same height as the floor 12 and that it is not in a blackout state. The control panel 210 has no passengers in the car 22, the doors 13 and 26 are completely closed, the floor 27 of the car 22 is approximately the same height as the floor 12, and the power failure If it is not in the state, it is determined as YES in step S126 of FIG. 7. Then, proceeding to step S110 in Fig. 5, the control panel 210, from the speaker of the telephone apparatus installed in the car 22, says, "Remote recovery is started from now on. The elevator door opens and closes.”

In addition, when the control panel 210 is in a power failure state in step S109 of FIG. 5 and it is confirmed that the elevator 20 is operating with the emergency battery, it waits until the power is restored, and when the power is restored, the process proceeds to step S125 of FIG. Proceed. In Step S125, the control panel 210 performs the same preparation operation as described above, and proceeds to Step S126 in FIG. 7. Then, if the control panel 210 determines YES in step S126 of FIG. 7, it proceeds to step S110 of FIG. 5 and announces remote recovery.

On the other hand, when the control panel 210 determines NO in step S126 in FIG. 7 after the preparation operation shown in step S125 in FIG. 7, it proceeds to step S127 in FIG. 7. In step S127, the control panel 210 outputs a notification that remote restoration is impossible to the remote monitoring center 310.

A notification of the inability to recover remotely 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. Thereby, the monitor 334 of the remote monitoring center 310 is notified that the elevator 20 is not remotely restored. When the monitor 334 confirms this display, as shown in step S128 of FIGS. 2 and 7, the monitor 334 instructs the elevator 20 to stop operating and performs an announcement operation. In addition, the supervisor 334 dispatches the technician 350 to the building 10 to the service center 340 near the building 10 as shown in step S129 of FIGS. 2 and 7 by the telephone 333 Instruct them to do.

When the control panel 210 determines YES in step S109 of FIG. 5 or step S126 of FIG. 7 and proceeds to step 110 of FIG. 5 to perform an announcement, the control panel 210 proceeds to step S111 of FIG. 5 and performs a recovery operation according to the recovery command. Run. The currently received recovery command is ``door circuit reset + door high torque open/close'', which is a recovery command that executes a recovery operation corresponding to the accumulation of garbage on the door sill (failure factor 1). Therefore, the control panel 210 first, The door circuit of the control panel 210 is reset. This command resets the state in which the door circuit detects that the door 26 or the door 13 is incapable of opening and closing, the open (or closed) state, or the half open (or half closed) state, and the door 13 Or, it is a command for making the door 26 open and close. Next, the control panel 210 increases the torque of the drive motor of the door 13 and the door 26 by 20 to 30% higher than normal to open and close the door 13 and the door 26 with a greater force than normal. This operation is an operation of moving the garbage accumulated on the door sill from the sill, and restoring the opening and closing operation of the doors 13 and 26 to a normal state. In order to check whether the trash accumulated on the threshold of the doors 13 and 26 is moved by the above operation and the opening and closing of the doors 13 and 26 is restored, the control panel 210 is shown in step S112 of FIG. As described above, "door opening/closing diagnosis", which is a restoration diagnosis command, is executed. The control panel 210 opens and closes the door 13 and the door 26 with a normal torque, and whether the opening and closing operation is performed at a predetermined opening and closing time, and the current of the driving motor of the door 13 and the door 26 is normal. Check if it is larger than. Next, the control panel 210 opens and closes the doors 13 and 26 by lowering the torque of the drive motor by about 20% lower than usual, and checks whether there is any abnormality in the opening and closing time.

Then, the control panel 210 proceeds to step S114 of FIGS. 2 and 6 when it is determined 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. 6. do. In step S114, the control panel 210 outputs a determination result signal indicating 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. 6, and the determination result is input to the information processing device 360. Further, the determination result is notified to the remote monitoring center 310 from the information processing device 360 as shown in step S116 in FIG. 6, 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. 6, the elevator 20 resumes operation and makes an announcement operation. Further, the information processing device 360 updates the maintenance database 370 and the restoration diagnosis database 380 as shown in steps S118 and S119 in FIG. 6.

On the other hand, when the control panel 210 determines NO in step S113 of FIG. 6 as a result of the recovery diagnosis operation, it proceeds to step S120 of FIG. 6. In step S120, the control panel 210 outputs a determination result signal indicating that the 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 S121 in FIG. 6, and the determination result is input to the information processing device 360. In addition, the determination result is notified to the remote monitoring center 310 from the information processing device 360 as shown in step S122 in FIG. 6, and the result is displayed on the display 331 of the remote monitoring center 310. . When the monitor 334 confirms this display, as shown in step S123 of FIG. 6, the monitor 334 performs an instruction of stopping the operation of the elevator 20 and an announcement operation. In addition, the supervisor 334 dispatches the technician 350 to the building 10 to the service center 340 near the building 10 as shown in step S124 in FIGS. 2 and 6 over the telephone 333 Instruct them to do. Further, the information processing device 360 updates the maintenance database 370 and the restoration diagnosis database 380 as shown in steps S118 and S119 in FIG. 6.

When a determination signal indicating that the elevator 20 has been restored as shown in step S114 of FIG. 6 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 restored as shown in step S114 of FIG. 6 is input, the information processing device 360 returns "remote recovery" to the item of the recovery method of the failure history data 377. "Recovery" is stored in the item of the judgment result. As described above, when the communication device 320 receives a failure signal, the information processing device 360 receives the failure code "0001" input from the communication device 320, the control number of the elevator 20, and a failure occurs. The date and time are stored in the failure history data 377 of the maintenance database 370. Accordingly, all items of the failure history data 377 are updated by the current recovery method and the storage of the recovery determination result.

Further, in this remote recovery, the information processing device 360 refers to the recovery diagnosis database 380, and in the case of a failure code "0001" as a recovery command, garbage accumulation on the door sill, which is the most frequent failure factor ( ``Door circuit reset + door open/close retry'', which is a restoration command that executes a restoration operation corresponding to the cause of failure 1), and ``door open/close diagnosis,” which is a restoration diagnosis command to execute a restoration diagnosis operation corresponding to the result of this restoration operation The recovery diagnosis command set A, which consists of two of is selected, and the recovery operation and the recovery diagnosis operation are executed. Therefore, in the case of successful restoration of the elevator 20, the number of failure codes "0001" and failure factor 1 (the accumulation of garbage on the door sill) in the restoration diagnosis database 380 is increased by one, and the number of cases of the restoration is as many as those who succeeded in restoration. Increase the recovery rate. Further, the information processing device 360 increases the number of failure factors 1 of the failure code "0001" of the data 378 for each failure factor by one.

On the other hand, when a determination signal indicating that the restoration of the elevator 20 has failed as shown in step S120 of FIG. 6 is input, the information processing device 360, as follows, the maintenance database 370 and the restoration diagnosis database ( 380). When a determination signal indicating that the restoration of the elevator 20 has failed as shown in step S120 of FIG. 6 is input, the information processing device 360 returns "remote restoration" to the item of the restoration method of the failure history data 377. , "Failure" is stored in the item of the recovery determination result. Further, the number of failure codes "0001" and failure factor 1 (garbage accumulation on the door sill) in the restoration diagnosis database 380 are kept as it is, and the restoration rate is reduced by the number of failures in restoration. In addition, when recovery fails, the number of failure factors 1 of the failure code "0001" of the failure factor data 378 is not changed.

In the above description, the case where the information processing device 360 selects the recovery diagnosis command set A based on the most frequent failure factor corresponding to the failure code "0001" has been described. When the information processing device 360 selects the recovery diagnostic command set B based on the recovery rate of the recovery diagnostic command set corresponding to the fault code "0001", instead of the recovery operation of "door high torque opening and closing", the normal torque The difference is that the restoration operation of "door open/close retry" in which the open/close operation of the furnace doors 13 and 26 is performed again is performed. Other operations are the same as those in the case where the recovery diagnosis command set A is selected.

If the remote restoration of the elevator 20 is successful, the number of garbage accumulation on the door sill (failure factor 1), which was the most frequent failure factor in the case of the failure code "0001" until then, increases. For this reason, when the remote recovery system 100 selects the recovery diagnosis command set based on the number of fault factors corresponding to the fault code "0001", the fault code "0001" was input at the next remote recovery. At this time, the information processing device 360 selects the restoration diagnosis command set A again. In addition, when the recovery rate of the recovery diagnostic command set A is higher than the recovery rate of the recovery diagnostic command set B, the information processing device 360 returns the command with the highest recovery rate among a plurality of commands corresponding to the failure code "0001". Even in the case of selecting as, the recovery diagnosis command set A is selected.

On the other hand, if the remote restoration of the elevator 20 fails, the number of failure factors 1 of the failure code "0001" of the failure factor data 378 is not changed, but the restoration rate of the restoration diagnosis command set A decreases. Thereby, the recovery rate of the recovery diagnosis command set B is relatively high. In other words, the recovery rate ratio of the recovery diagnostic command set B to the recovery diagnostic command set A increases. When this recovery rate ratio is greater than the ratio of the number of cases calculated as the ratio of the number of failure factor 1 to the number of failure factor 2, the information processing device 360 is a command with the highest recovery rate among a plurality of commands corresponding to the failure code "0001". Is selected as the recovery command. For this reason, when the failure code "0001" is input at the next remote recovery, the information processing device 360 selects the recovery diagnostic command set B having the highest recovery rate. In addition, when the information processing device 360 does not select the recovery diagnostic command set A that failed to recover in the previous remote recovery, the number of cases corresponding to the fault code "0001" after the fault factor 1 is applied to the fault factor 2. Select the linked recovery diagnostic command set B.

In addition, when the information processing device 360 selects the recovery diagnostic command set B with the highest recovery rate from among a plurality of commands corresponding to the failure code "0001" and successfully restores the elevator 20, the recovery diagnostic command set B The recovery rate of is higher. Therefore, in the next remote restoration, the restoration diagnosis command set B is selected as in the previous time. On the other hand, when restoration of the elevator 20 fails with the restoration diagnosis instruction set B, the restoration rate of the restoration diagnosis instruction set B is lowered. Then, when the restoration rate of the restoration diagnosis instruction set B is lower than the restoration rate of the restoration diagnosis instruction set A, the information processing device 360 selects the restoration diagnosis instruction set A. In addition, when the information processing device 360 does not select the recovery diagnostic command set B that failed to recover in the previous remote recovery, the recovery diagnostics with a high recovery rate corresponding to the failure code "0001" following the recovery diagnostic command set B Select command set A.

In this way, when remote recovery is successful, the remote recovery system 100 increases the number of failure factors and a recovery rate of the selected recovery diagnosis command set. In addition, when remote recovery fails, the remote recovery system 100 lowers the recovery rate of the selected recovery diagnosis command set while maintaining the number of failure factors. For this reason, if remote recovery is successful, there is a high possibility that the recovery diagnostic command set selected in the remote recovery will be selected at the next remote recovery. Further, if the remote recovery fails, the possibility that the recovery diagnostic command set selected in the remote recovery will be selected at the next remote recovery is lowered. For this reason, as the number of remote restorations increases, the information processing apparatus 360 can select a restoration diagnosis command set with a high restoration possibility corresponding to the failure code from the restoration diagnosis database 380, and the elevator 20 You can improve the certainty of recovery.

In the above, the case of "0001" indicating that the fault code is a fault with respect to the doors 13 and 26 has been described. Next, the case of "0002" indicating that the fault code is a fault related to the brake will be described. Description of the part in which the fault code is the same as "0001" is omitted.

If the fault code is 0002 indicating a breakdown related to the brake, as a result of a local inspection by the technician 350, the factor in which the fault code "0002" was output is the cause of an abnormality in the brake circuit of the control panel 210 (failure factor 4 ), or other failure factor 5 or failure factor 6. Therefore, in the case of the failure factor data 378, in the case of the failure code "0002", 100 cases were caused by an abnormality in the brake circuit (failure factor 4), 50 cases were the failure factor 5, and 6 other failure factors. The data structure is the same as 10 cases, and data is arranged in the order of the largest number of cases. As described above, in the case of recovery by the remote recovery system 100, the total number of fault factors corresponding to the fault code that is the basis of the recovery command when the elevator 20 is successfully recovered by the recovery command Is added to the number of causes of failure.

As shown in Fig. 8, the recovery diagnosis database 380 is a database obtained by linking the recovery diagnosis command set and the recovery rate to the data 378 for each failure factor. Hereinafter, the data configuration of the recovery diagnosis database 380 in the case where the fault code is "0002" indicating a breakdown related to the brake will be described. When an abnormality in the brake circuit is a factor (failure factor 4), the recovery diagnostic data is the number of fault factor 4 data and two commands: ``control circuit reset'' as a recovery command and ``brake torque diagnosis'' as a recovery diagnosis command. It has a data structure in which a set-in recovery diagnostic command set G is linked with a recovery rate a% by a recovery operation by this recovery diagnostic command. In the case of failure factor 5 and failure factor 6, the recovery diagnosis data is a link between the recovery diagnosis command set H and the recovery rate b%, and the recovery diagnosis command set I and the recovery rate c% to the data of the number of failure factors 5 and 6 respectively. It is composed of data. In this way, the recovery diagnostic database 380 is a database by correlating a fault code, a fault factor corresponding to the fault code, the number of fault factors, a recovery diagnostic command set that is a set of recovery commands and recovery diagnostics, and a recovery rate. It was stored in. In addition, as for the recovery rate, b% of the recovery diagnosis command set H is the highest.

Next, the operation of the remote recovery system 100 when the control panel 210 detects a breakdown related to the brake will be described.

When the fault code is "0002", the information processing device 360 in step S106 of FIG. 5 causes the information processing device 360 to command the recovery diagnosis based on the number of fault factors corresponding to the fault code "0002". When the set G is selected, the information processing device 360 transmits the restoration diagnosis command set G to the control panel 210.

When the failure code is "0002", upon receiving this restoration diagnosis command set G, the control panel 210 checks whether the elevator 20 shown in step S109 of FIG. 5 can start remote restoration, the failure code is In addition to the check item in the case of "0001", the brake torque diagnosis operation is performed. The brake torque diagnosis operation is an operation to confirm that the hoisting machine in the drive device 24 does not rotate with a mechanical brake, and a driving force is applied to the hoisting machine to confirm that the hoisting machine does not rotate with the holding force of the brake. If there is no abnormality in this operation, on the other hand, as in the case where the fault code is ``0001'', when there are no passengers in the car 22, the doors 13 and 26 are in a completely closed state, and not in a power failure state , The control panel 210 determines YES in step S109 in FIG. 5 and proceeds to step S110 in FIG. 5. Then, in step S110, after the control panel 210 announces the remote restoration, it proceeds to step S111 in FIG. 5. Then, in step S111, the control panel 210 performs a control circuit reset operation.

After that, the control panel 210 executes a brake torque diagnosis operation in step S112. When there is no rotation of the hoisting machine by this operation, the control panel 210 outputs a determination result that the restoration of the elevator 20 is successful. In addition, when the hoisting machine rotates, a determination result in which restoration of the elevator 20 has failed is output. This determination result is input from the control panel 210 to the information processing device 360 via the communication devices 250 and 320. The information processing device 360 updates the failure history data 377, the data for each failure factor 378, and the restoration diagnosis database 380 so that the restoration diagnosis command set with high restoration possibility can be selected based on the determination result. .

In addition, in the brake torque diagnosis operation of step S112, the control panel 210 determines that the elevator 20 can only run at a low speed when the hoisting machine has moved slightly in the rotational direction, and the elevator 20 partially recovers. You may output the result of the judgment that succeeded in In this case, the control panel 210 indicates that the elevator 20 is in a state of being operable by limiting some functions such as high-speed driving, such as a display device in the car 22 or next to or above the door 13 of each floor. It is displayed on the display device of and notifies the user of the elevator 20. Further, the determination result of the partial restoration success is input from the control panel 210 to the information processing device 360 through the communication devices 250 and 320. The information processing device 360 updates the failure history data 377, the failure factor data 378, and the recovery diagnosis database 380 based on the determination result.

In addition, as described above, the information processing device 360 may select the recovery diagnostic command set H with the highest recovery rate corresponding to the fault code "0002" to cause the control panel 210 to perform a recovery operation and a recovery diagnostic operation. .

In addition, the control panel 210, when there is an abnormality in the brake torque diagnosis operation, or when there are passengers in the car 22, the doors 13 and 26 are not completely closed, or when there is a power failure, In step S109 of 5, it is determined as NO. Then, the process proceeds to step S127 in FIG. 7, and the control panel 210 notifies the remote monitoring center 310 that remote restoration is impossible.

As described above, the remote recovery system 100 is not a temporary factor such as noise, but even when any abnormality actually occurs, the remote recovery system 100 receives a command from the remote recovery device 300 disposed at a place away from the elevator 20. The elevator 20 can be repaired by executing a repair operation and a repair diagnosis operation on the elevator 20. This allows the elevator 20 to be restored in a short time without dispatching the technician 350 to the site when a failure occurs in the elevator 20 even when a failure occurs in the elevator 20 even when an abnormality occurs, rather than a temporary factor such as noise. I can. Accordingly, it is possible to improve the operation service of the elevator 20.

In addition, the remote recovery system 100, based on the recovery determination result, to select a recovery diagnostic command set with a higher recovery probability at the next remote recovery, failure history data 377, failure factor data 378 , The recovery diagnosis database 380 is updated. Thereby, as the number of times of remote restoration 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. In this way, it is possible to reliably restore the elevator 20. Accordingly, it is possible to improve the operation service of the elevator 20 by shortening the time required for recovery.

In addition, when the elevator 20 is partially restored and can be operated by restricting some functions, the remote recovery system 100 may limit some functions of the elevator 20 to resume service. Accordingly, it is possible to improve the operating service of the elevator 20 by shortening the period during which the operating service of the elevator 20 is stopped.
