Description

  Embodiments described herein relate generally to an elevator system and a display device.

  As a system that links a building security system and an elevator group management system, there is a system that links a security gate and a destination floor registration device. In recent years, this system has been introduced in buildings such as office buildings, and when a user passes through a security gate installed on the standard floor of the building, the information on the security card carried by the user is read and When the user can be authenticated, the system opens the gate and automatically registers the destination floor of the user.

  When a machine that responds to a user's destination floor is determined when the user's destination floor is automatically registered, information on the machine is displayed on a display provided on the security gate. As a result, the user can confirm the car that the user should get on when passing through the gate, and can wait in front of the boarding place of the car.

Hereinafter, embodiments will be described with reference to the drawings.
FIG. 1 is a schematic configuration diagram illustrating a configuration of an elevator system according to an embodiment. In the present embodiment, a system in which a security gate and a destination floor registration device are linked will be described. That is, it is assumed that the security gate functions as a destination floor registration device in addition to preventing outsiders from entering.

  The security gate 11 shown in FIG. 1 is installed on a reference floor of a building such as an office building. In the case of an office building, the reference floor refers to a floor with a lot of traffic such as a lobby. Although only one security gate is illustrated in FIG. 1, the number of security gates is not limited to this, and a plurality of security gates may be installed side by side. On the exit side of the security gate 11, a door (gate) 12 for preventing entry is attached to be openable and closable. In the vicinity of the entrance of the security gate 11, information on the security card SC possessed by the user (hereinafter referred to as “user information”) is read, and whether or not the owner of the security card SC is a legitimate user. A user authentication unit 13 is provided for authenticating the above. The method for reading the user information from the security card SC may be any method, starting with the electromagnetic induction method.

  As shown in FIG. 2, the user information includes a user ID for identifying a user who is the owner of the security card SC and destination floor information indicating the destination floor (also referred to as a destination floor) of the user. Information that contains at least. For example, the user information A1 in FIG. 2 indicates that the user ID is “user1” and the destination floor of the user identified by the user ID “user1” is “fifth floor”. In addition to the above-described user ID and destination floor information, the user information is, for example, the attributes of the user, more specifically, what kind of person the user is (for example, the user's gender, age, wheelchair, etc. It may further include attribute information indicating whether or not the user is.

  When the user authentication unit 13 reads the user information from the security card SC, the user ID included in the user information is a user database (hereinafter referred to as “user DB”) 14 provided in the security gate 11. It is determined whether or not it matches the user ID registered in advance, and it is authenticated whether or not the user is a legitimate user. For example, when the read user information is the user information A1 in FIG. 2, the user authentication unit 13 determines whether the user ID “user1” is registered in the user DB 14 and performs regular use. Authenticate whether or not The user DB 14 may be provided separately from the security gate 11 as an external server device capable of communicating with the security gate 11 instead of within the security gate 11.

  As a result of the authentication, the user authenticating unit 13 registers the hall call to the assigned car control device 50 described later when the owner of the security card SC can be authenticated as an authorized user. Specifically, the user authentication unit 13 registers a hall call including the destination floor indicated by the destination floor information included in the read user information. More specifically, a hall call for registering an elevator heading for the destination floor indicated by the destination floor information included in the read user information to the installation floor of the security gate 11 is registered.

  In the vicinity of the exit of the security gate 11, a display unit (display) 15 made of a liquid crystal panel or the like is provided. The display unit 15 displays at least unit information indicating the unit assigned to the user (hereinafter referred to as “assigned unit”). For example, according to the display of FIG. 3, it is understood that the user should wait for the elevator before the landing of “No. X”. In addition to the above-mentioned number information, the display unit 15 may further display, for example, a direction to a landing where the assigned number stops. The display unit 15 may be provided separately from the security gate 11 as long as it is provided near the exit of the security gate 11 (for example, suspended from the ceiling near the exit of the security gate 11).

  In front of the security gate 11, a platform 20 for a plurality of units is provided. In addition, in the example of FIG. 1, although the case where three of A-C No. 3 is adjoined is illustrated, the number of cars is not limited to this, and if at least two Nos. good.

  In the present embodiment, the “elevator” is basically referred to as a “car”, and when a plurality of cars are described, it is referred to as a “car”. In the present embodiment, it is assumed that the distance from the security gate 11 to the landing 20 is a predetermined distance or more.

  The group management control device 30 is a device for performing group management control of the operation of each unit. The group management control device 30 is connected to elevator control devices (also referred to as single control devices) 40A, 40B, and 40C corresponding to the respective units. That is, the group management control device 30 controls the operations of these elevator control devices 40A to 40C, and performs group management control on the operation of each unit. For example, the group management control device 30 outputs an allocation signal that instructs the elevator control device 40 corresponding to a predetermined car to respond to a predetermined hall call.

  Each of the elevator control devices 40A to 40C individually controls the operation of each unit. Specifically, control of a motor for raising and lowering the car, opening / closing control of a door, and the like are performed. In addition, each elevator control device 40A to 40C is output from the group management control device 30 and state information indicating the operation state (current position of the car, driving direction, door open / closed state, presence / absence of abnormality, etc.) of the corresponding car. Response availability information indicating whether or not the allocation signal can be responded (in other words, indicating whether or not the hall call can be answered) is periodically sent to the group management control device 30 and the allocation car control device 50 ( (For example, every 0.5 seconds, every second, etc.)

  The assigned car control device 50 periodically acquires status information and response availability information from each of the elevator control devices 40A to 40C, and records them in a temporary memory (not shown). The status information and response availability information recorded in the temporary memory are updated each time new status information and response availability information are received.

  The assigned car control device 50 registers the hall call from a plurality of units based on the status information recorded in the temporary memory (not shown) in accordance with the registration of the hall call including the destination floor from the user authentication unit 13. A suitable machine is selected. Further, the assigned car control device 50 determines whether or not a suitable selected car can respond to the hall call based on response availability information recorded in a temporary memory (not shown). Furthermore, the assigned car control device 50 outputs to the group management control device 30 an assignment command that instructs the elevator control device 40 corresponding to the selected preferred car to output an assignment signal. For example, when the selected preferred car is No. A, the assigned car control device 50 gives an assignment command to the group management control device 30 to instruct the elevator control device 40A corresponding to the No. A to output an assignment signal. Output.

  The assigned car control device 50 transmits to the security gate 11 car number information with the selected suitable car number as the assigned car number. The assigned car control device 50 records at least the most recently transmitted car information as a log in a temporary memory (not shown). When the security gate 11 receives the car information transmitted from the assigned car control device 50, the security gate 11 displays the car information on the display unit 15.

  The assigned car control device 50 is preferably installed on the same floor as the security gate 11, that is, on the reference floor. However, the installation location of the assigned car control device 50 is not limited to this, and may be any location as long as it can communicate with the security gate 11. Further, the group management control device 30 may have various functions that the assigned car control device 50 has.

  Here, before describing the operation of the elevator system according to the present embodiment, a system in which a general security gate and a destination floor registration device are linked will be briefly described.

  In a system in which a general security gate and a destination floor registration device are linked, first, the group management control device considers the operation status of each unit for calls registered by the security gate (destination floor registration device). Then, a suitable number is selected from a plurality of numbers. Subsequently, the group management control device outputs an answer request asking whether or not the registered call can be answered to the elevator control device corresponding to the selected preferred car, and can respond from the elevator control device. If an answerback is obtained, the unit is officially assigned. Thereafter, the group management control device transmits number information indicating the assigned number to the security gate in order to notify the user of the number to be boarded.

  In this case, even though a suitable number of units is selected from among a plurality of units, an answer request asking whether or not the registered call can be answered is output, and an answer back indicating that the response is possible is obtained. In this case, since the assigned number machine is determined, it may take time until the number machine information indicating the assigned number machine is transmitted to the security gate. According to this, since it takes time until the assigned machine is displayed on the display unit provided in the security gate, there may be a disadvantage that the user stays near the exit of the security gate.

  For this reason, in the elevator system according to the present embodiment, a suitable number is selected using the state information and response availability information that are periodically acquired, and the availability of response to the registered call is determined, and the assigned number is quickly set. The configuration is fixed. Hereinafter, an example of the operation of the elevator system according to the present embodiment will be described with reference to the flowchart of FIG.

  FIG. 4 is a flowchart illustrating an example of the operation of the elevator system according to the embodiment. However, user information including a user ID and destination floor information is recorded in advance in the security card SC possessed by the user, and the user ID of the authorized user is registered in advance in the user DB 14, and the assigned car control device It is assumed that state information and response availability information that are periodically acquired from each of the elevator control devices 40A to 40C are recorded in a temporary memory (not shown) in 50.

  First, when the security card SC is held over the user authentication unit 13 provided in the security gate 11, the user authentication unit 13 reads user information recorded in advance on the security card SC (step S1).

  Subsequently, the user authentication unit 13 determines whether or not the user ID included in the read user information matches any of a number of user IDs registered in advance in the user DB 14 (step S2). As a result of this determination, when the user ID included in the user information does not match any user ID registered in the user DB 14 (NO in step S2), the user authentication unit 13 determines that the owner of the security card SC Determines that the user is not a legitimate user, displays a message on the display unit 15 prompting the user to hold the security card SC again with the door 12 of the security gate 11 closed (step S3). Terminate.

  On the other hand, when the user ID included in the user information matches the user ID registered in the user DB 14 (YES in step S2), the user authentication unit 13 indicates that the owner of the security card SC is a legitimate user. The door 12 of the security gate 11 is opened (step S4), and a hall call including the destination floor indicated by the destination floor information included in the read user information is registered (step S5).

  When the hall call registration is performed, the assigned car control device 50 selects a suitable car from a plurality of car based on the state information recorded in a temporary memory (not shown) (step S6). Based on the response availability information recorded in a temporary memory (not shown), it is determined whether or not the selected suitable number can respond to the hall call (step S7). Note that, as a result of this determination, if the selected suitable car cannot respond to the hall call (NO in step S7), the process returns to the above-described step S6, and the assigned car control device 50 re-selects another suitable car. Try again.

  On the other hand, as a result of the above determination, if the selected suitable number machine can respond to the hall call (YES in step S7), the assigned car control device 50 secures the machine information with the selected preferred number as the assigned number. Transmit to the gate 11 (step S8). At this time, the assigned car control device 50 records the car number information transmitted to the security gate 11 in a temporary memory (not shown) as a log.

  When the security gate 11 receives the car information transmitted from the assigned car control device 50, the security gate 11 displays the car information on the display unit 15 (step S9).

  In parallel with the transmission of the unit information, the allocation car control device 50 outputs an allocation command for instructing the elevator control device 40 corresponding to the selected preferable number to output an allocation signal to the group management control device 30. (Step S10).

  When the group management control device 30 receives the allocation command output from the allocation car control device 50, the group management control device 30 outputs an allocation signal to the elevator control device 40 corresponding to a suitable car (step S11). Thereafter, when the elevator control device 40 receives the assignment signal output from the group management control device 30, the elevator control device 40 responds to the registered hall call (step S12), and ends the processing here.

  According to the operation of FIG. 4 described above, the assigned car control device 50 selects a suitable car using the periodically acquired status information and response availability information, and whether or not to respond to the registered hall call. Since the assigned machine number can be determined quickly and the machine information can be transmitted to the security gate 11, the above-mentioned inconvenience can be solved.

  Here, with reference to FIG.5 and FIG.6, the difference between the system which linked the general security gate and the destination floor registration apparatus, and the elevator system which concerns on this embodiment is demonstrated supplementarily. FIG. 5 is a sequence diagram showing an example of an operation from registration of a hall call to display of unit information in a system in which a general security gate and a destination floor registration device are linked. These are the sequence diagrams which show an example of operation | movement until registration of hall information is displayed in the elevator system which concerns on this embodiment after registration of a hall call is made.

  As described briefly above, in a general system, as shown in FIG. 5, after selecting a suitable number machine, the group management control device communicates with the elevator control device, outputs an answer request, and The assigned machine is determined after the answerback from the control device is obtained.

  On the other hand, in the elevator system according to this embodiment, as shown in FIG. 6, the assigned car control device 50 can determine the assigned number without communicating with the elevator control device 40 after selecting a suitable number. . That is, according to this elevator system, the answer request and answerback processing required in a general system can be omitted, and it is not necessary to communicate with the elevator controller 40. Compared to, it is possible to determine the assigned machine quickly.

  On the other hand, since response availability information recorded in a temporary memory (not shown) is not always the latest response availability information (for example, when response availability information is acquired every 0.5 seconds, when response availability is determined. Because the response availability information of 0.5 seconds ago is used and the situation may be different from the current situation), although the operation efficiency of the elevator may be slightly lower than that of a general system, the security gate The great advantage of being able to reduce the stagnation of users near the 11 exits can be obtained.

  Next, referring to the flowchart of FIG. 7, immediately after transmitting the machine information to the security gate 11 (for example, after 0.5 seconds), the status information periodically acquired from each of the elevator control devices 40A to 40C and The operation of the elevator system when it is found that an abnormality has occurred in a predetermined car based on the response availability information and the predetermined car cannot respond to the hall call will be described.

FIG. 7 is a flowchart illustrating an example of another operation of the elevator system according to the embodiment.
The assigned car control device 50 periodically acquires status information and response availability information from each of the elevator control devices 40A to 40C. At this time, if the acquired status information and response availability information indicate that an abnormality has occurred in a predetermined car and that it is impossible to respond to the hall call, the assigned car control device 50 is recorded as a log in a temporary memory (not shown). Then, it is confirmed whether or not the assigned number indicated by the number information transmitted most recently to the security gate 11 is a number that cannot respond to the hall call (step S21).

  As a result of the confirmation, if it is confirmed that the assigned car is not a car that cannot respond to the hall call (NO in step S21), the process here is terminated.

  On the other hand, as a result of the confirmation, if it is confirmed that the assigned car is a car that cannot respond to the hall call (YES in step S21), the assigned car control device 50 holds the security card SC over the user authentication unit 13 again. Message information for prompting the user is transmitted to the security gate 11 (step S22). When the security gate 11 receives the message information transmitted from the assigned car control device 50, the message information is displayed on the display unit 15 in place of the machine information currently displayed on the display unit 15, as shown in FIG. While displaying, the door 12 is closed (step S23), and the process here is terminated.

  According to the operation of FIG. 7 described above, message information for prompting to hold the security card SC again and register a hall call again even if an abnormality occurs in the assigned machine immediately after the assigned machine is confirmed. Can be displayed on the display unit 15 instead of the machine information, so that it is possible to reduce the possibility that the user will accidentally go to the machine that cannot respond to the hall call.

  Note that a step of determining whether or not an elapsed time after transmitting the machine information to the security gate 11 exceeds a predetermined time immediately after the process of step S21 described above may be added. By adding this step, it is possible for the user to check the wrong machine information and determine whether or not the security gate 11 has already been passed. The possibility that the message information is erroneously displayed can be reduced.

  According to the embodiment described above, it is possible to reduce the time required for displaying the information on the number machine on the display (display unit 15).

  In addition, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
