Description

[Technical Field]

[0001] An embodiment of the present invention relates to an elevator control device and a program. [Background technology]

[0002] Buildings equipped with elevators may have a security gate through which users must pass before heading to the elevator hall (landing). The security gate or its vicinity may also be equipped with a personal information recognition device for identifying individual users, as well as a hall destination floor registration device for users to register their destination floor calls. In this case, a display device installed on or near the hall destination floor registration device displays information informing the user of the elevator number assigned to that user. The elevator hall may also be equipped with another hall destination floor registration device with the same functionality as the hall destination floor registration device.

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-045509 [Patent Document 2] Japanese Patent Application Publication No. 2019-156577 Summary of the Invention [Problem to be solved by the invention]

[0004] In buildings such as those described above, if there is a certain distance between the security gate and the elevator hall (landing), some users may take longer than a certain amount of time to arrive at the elevator hall from the security gate, causing them to miss their assigned elevator car.If a user determines that they have missed their assigned elevator car, they will use the elevator hall destination floor registration device installed in the elevator hall to register their destination floor call again.

[0005] However, because the destination floor call registration is performed at the discretion of the user, there are cases where the user has not actually missed the assigned elevator and the assigned elevator has not yet responded. In such cases, the destination floor call registered by the user becomes a useless call (waste call), reducing the elevator operation efficiency.

[0006] The problem to be solved by the invention is to provide an elevator control device and program that can prevent unnecessary calls from occurring. [Means for solving the problem]

[0007] The elevator control device of the embodiment comprises: an information management unit that manages, for each user, information indicating whether an assigned elevator assigned to a user who has registered a destination floor call at a security gate has responded or not; and a control execution unit that displays, on a display device of a hall destination floor registration device provided in the elevator hall, information indicating a user ID of the user and the assigned elevator, and, when a destination floor call registration for a user who registers a destination floor call at the hall destination floor registration device provided in the elevator hall already exists and the assigned elevator assigned to the user is not responding, invalidates the destination floor call registration of the user in the elevator hall. When the control execution unit invalidates the call registration for the destination floor in the elevator hall, the control execution unit notifies the user who registers the call for the destination floor in the elevator hall of information indicating that the assigned elevator has not responded or information indicating the remaining time until the assigned elevator responds. .

[0009] Hereinafter, embodiments will be described with reference to the drawings.

[0010] <System configuration> FIG. 1 is a diagram illustrating an example of the configuration of an elevator system according to an embodiment.

[0011] The elevator system shown in Fig. 1 is installed in a building and includes a security gate 10 through which users must pass before heading to the elevator hall, a first elevator 21, a second elevator 22, and a third elevator 23 that make up a plurality of (e.g., three) elevators, cars 31, 32, and 33 provided in each of the elevators 21, 22, and 23, a first elevator control device 41, a second elevator control device 42, and a third elevator control device 43 that control the operation of each of the elevators, and an elevator control device (group management control device) 100 that controls each of the elevator control devices 41, 42, and 43. Note that security gate 1 need not be installed on only one floor, but may also be installed on other floors in the same manner.

[0012] Furthermore, the elevator system shown in Figure 1 includes a plurality of landing destination floor registration devices 60 installed in the elevator hall (for example, near the landings of each elevator 21, 22, 23), and landing destination floor display devices 71 to 73 installed near the landing doors of each elevator 21 to 23, respectively.

[0013] There are provided a plurality of security gates 10. Each security gate 10 is configured as, for example, a flapper gate, and allows entry to the elevator hall only if the user attempting to pass through matches a user registered in advance, and opens a door or the like to allow the user to pass through.

[0014] FIG. 2 shows an example of the configuration of one security gate 10.

[0015] As shown in Fig. 2, the security gate 10 includes a personal information recognition device 11 and a hall / destination floor registration device 12 provided in a gate main body 10A. The configuration of the security gate 10 is not limited to that shown in Fig. 2 and may be modified as appropriate. For example, the personal information recognition device 11 and the hall / destination floor registration device 12 may each be installed at a location within a certain distance from the gate main body 10A.

[0016] The personal information recognition device 11 determines whether a user attempting to pass through matches a pre-registered user. In this example, an authentication card is used to enter a building. By reading information such as a user ID recorded on the authentication card, the user attempting to pass through the security gate 10 can be identified from that information, and whether the user matches a pre-registered user can be determined by matching. The matching is performed through communication with the elevator control device 100. For example, when the personal information recognition device 11 sends a user ID to the elevator control device 100, the elevator control device 100 returns the matching result to the personal information recognition device 11. Note that instead of using an authentication card, the user may be identified by fingerprint authentication, iris authentication, face authentication, or the like using a biometric authentication device or a photographing device.

[0017] The landing destination floor registration device 12 installed at the security gate 10 is a device used for registering calls for destination floors that users wish to go to. The landing destination floor registration device 60 installed in the elevator hall has the same functions as the landing destination floor registration device 12.

[0018] FIG. 3 shows an example of a configuration common to the landing-destination floor registration device 12 and the landing-destination floor registration device 60. As shown in FIG.

[0019] As shown in Fig. 3, the landing destination floor registration device 12 and the landing destination floor registration device 60 include an input device 61 (such as a keypad) that is used by a user to specify a destination floor where the user wants to go, and a display device 62 (such as a liquid crystal display) that displays information indicating the destination floor where the user wants to go and information indicating the assigned elevator car number assigned to the user. The display device 62 may display a guidance message for the user. A speaker may be provided so that guidance can be provided by voice in addition to visual guidance.

[0020] The shapes of the platform destination floor registration device 12 and the platform destination floor registration device 60 are not limited to those shown in Fig. 3 and may be changed as appropriate. For example, the platform destination floor registration device 12 and the platform destination floor registration device 60 may have different shapes. The input device 61 and the display device 62 may be realized in the form of a touch panel. The display device 62 may be provided independently from the platform destination floor registration device main body.

[0021] The landing destination floor display devices 71 to 73 display information indicating the individual floors registered as destination floors for the cars 31, 32, and 33 of the elevators 21, 22, and 23, respectively.

[0022] <Various functions of elevator control device> The elevator control device 100 has, in particular, a function for managing, for each user, information indicating whether the assigned elevator assigned to a user who has registered a destination floor call at the hall destination floor registration device 12 of the security gate 10 has responded or not, and a function for invalidating (avoiding duplicate registrations) the destination floor call registration of a user at the elevator hall destination floor registration device 60 if a destination floor call registration for that user already exists and the assigned elevator assigned to that user is not responding.

[0023] FIG. 4 shows an example of the configuration of various functions provided in the elevator control device 100.

[0024] The elevator control device 100 is realized using one or more computers, and has, as various functions, an information acquisition unit 51, an operation information management unit 52, a situation determination unit 53, and a control execution unit 54. These are realized as functions of a program executed by the computer.

[0025] 4 is an example and is not limited to this example. Multiple functions may be integrated into one function, or one function may exist as multiple functions. For example, the operation information management unit 52 and the situation determination unit 53 may be integrated into one function.

[0026] ·Information acquisition unit 51 The information acquisition unit 51 acquires information indicating the operation status of each elevator (car) from the No. 1 elevator control device 41, the No. 2 elevator control device 42, and the No. 3 elevator control device 43, as well as information on the user ID of each user, the landing floor, and the call registration of the destination floor (hereinafter referred to as "information such as user ID") sent from the landing destination floor registration device 12 or the landing destination floor registration device 60. The acquired information is reflected in the information managed by the operation information management unit 52.

[0027] ·Operation information management department 52 The operation information management unit 52 uses the storage area of ​​a specified storage medium to manage information indicating the operation status of each elevator (car), and in particular, manages information for each user indicating whether the assigned elevator assigned to the user who has registered a call for a destination floor at the landing destination floor registration device 12 of the security gate 10 has responded or not.

[0028] FIG. 5 shows an example of information managed by the operation information management unit 52 for each user.

[0029] The management information 50 shown in Figure 5 includes various information for each user, such as "ID," "boarding floor," "destination floor," and "assigned vehicle," and indicates whether the assigned vehicle assigned to the user who registered a call for the destination floor has "responded" or "not responded."

[0030] "ID" is information indicating a user ID for identifying a user who has registered a call for a destination floor.

[0031] The "boarding floor" is information indicating the floor where a user who has registered a call for a destination floor will board.

[0032] "Destination floor" is information indicating the floor designated as the destination floor by the user who registered the call for the destination floor.

[0033] "Assigned car number" is information indicating the assigned car number assigned to the user who registered the call for the destination floor, and information identifying whether the assigned car number is "unanswered" or "answered" (already answered). In the case of "unanswered," information indicating the remaining time until the status changes to "answered" may be added.

[0034] The management information 50 is updated whenever the situation changes, and always shows new information. For example, each time a call registration for a destination floor by a user is validly accepted, one line of information about that user is added. Also, when an assigned elevator that was in an "unanswered" state changes to an "answered" state and a certain amount of time has passed, the information (one line) about the corresponding user may be deleted.

[0035] Situation Judgment Unit 53 The situation determination unit 53 makes various determinations based on the information acquired by the information acquisition unit 51 and the information managed by the operation information management unit 52. The results of the determinations are transmitted to the control execution unit .

[0036] For example, when information such as a user ID is sent to the elevator control device 100 from the landing destination floor registration device 12 or the landing destination floor registration device 60 (when acquired by the information acquisition unit 51), the situation determination unit 53 determines whether the user ID matches a pre-registered user ID (whether it indicates a legitimate user) and transmits the determination result to the control execution unit 54 together with the user ID.

[0037] In particular, when information such as a user ID is sent to the elevator control device 100 from the hall destination floor registration device 60 (when acquired by the information acquisition unit 51), the situation determination unit 53 determines whether a call registration for the destination floor for the user with that user ID (i.e., the user who registers a call for a destination floor at the hall destination floor registration device 60 in the elevator hall) already exists and whether the assigned elevator assigned to that user is in an "unresponsive" state, and transmits the determination result to the control execution unit 54 together with the user ID.

[0038] Control execution unit 54 The control execution unit 54 executes various controls and processes based on the various determination results obtained from the situation determination unit 53 and the information managed by the operation information management unit 52. The execution results are reflected in the information managed by the operation information management unit 52.

[0039] For example, when the situation determination unit 53 determines that the user ID indicates a legitimate user, the control execution unit 54 validly accepts the call registration for the user's destination floor, determines the assigned car to be assigned to the user, controls the appropriate one of the No. 1 car control device 41, No. 2 car control device 42, and No. 3 car control device 43 so that the car of the determined assigned car heads towards the floor where the user is waiting, and instructs the appropriate hall destination floor registration device to perform predetermined processing (such as displaying the user ID and displaying information indicating the assigned car).

[0040] In particular, when the situation determination unit 54 determines that a destination floor call registration already exists for a user who registers a destination floor call at the elevator hall destination floor registration device 60 in the elevator hall (for example, a destination floor call registration already exists at the elevator hall destination floor registration device 12 of the security gate 10), and that the assigned elevator number assigned to that user is in an "unresponsive" state, the control execution unit 54 will not accept the user's destination floor call registration at the elevator hall and will invalidate it, preventing the occurrence of useless calls, and will instruct the relevant elevator hall destination floor registration device 60 to execute a predetermined process (such as displaying the user ID and displaying information indicating the same elevator number as the assigned elevator number that has already been assigned).

[0041] On the other hand, if this is not the case (for example, if a call registration for the user's destination floor exists, but the assigned elevator assigned to the user is in the "answered" state), the call registration for the user's destination floor in the elevator hall is validly accepted, the assigned elevator to be assigned to the user is determined, and the appropriate one of the No. 1 elevator control device 41, No. 2 elevator control device 42, and No. 3 elevator control device 43 is controlled so that the car of the determined assigned elevator heads towards the floor where the user is waiting, and the appropriate hall destination floor registration device 60 is instructed to perform predetermined processing (such as displaying the user ID and displaying information indicating the newly assigned assigned elevator).

[0042] When the call registration for the destination floor is invalidated, the control execution unit 54 notifies a user who registers a call for the destination floor in the elevator hall of information indicating the assigned elevator that has already been assigned, by image or sound, through the display device 62 or speaker provided in the corresponding hall destination floor registration device 60. In this way, even if a user mistakenly believes that they have missed the assigned elevator when the assigned elevator has not responded and registers a new call for the destination floor, the notification is the same as usual, so the user does not feel uncomfortable.

[0043] Furthermore, when invalidating the call registration for the destination floor, the control execution unit 54 may further notify a user who registers a call for the destination floor in the elevator hall of information indicating that the assigned elevator has not responded by visual or audio means via the display device 62 or speaker provided in the corresponding hall destination floor registration device 60. In this way, the user can understand that he or she has not missed the assigned elevator, and therefore the user does not feel anxious.

[0044] Furthermore, when the destination floor call registration is disabled, the control execution unit 54 may further notify a user who registers a destination floor call in the elevator hall of information indicating the remaining time until the assigned elevator responds by image or sound via the display device 62 or speaker provided in the corresponding hall destination floor registration device 60. In this way, the user can know how long he or she has to wait, thereby increasing user satisfaction.

[0045] <Example of operation> Next, an example of the operation of the elevator control device 100 will be described with reference to the flowchart of FIG.

[0046] The elevator control device 100 repeatedly performs the series of processes described below for each floor on which a security gate 10 is installed.

[0047] 6, LS and LE respectively represent the start and end of a series of processes (floor loop) carried out for each floor. Between LS and LE there are a plurality of steps S1 to S7.

[0048] In step S1, when the elevator control device 100 acquires information such as the user ID of a user who has registered a destination floor call with the hall destination floor registration device 12 of the security gate 10, it determines whether the user ID indicates a legitimate user. If it is determined that the user ID indicates a legitimate user, it validly accepts the user's destination floor call registration, determines the assigned car to be assigned to the user, and controls the appropriate one of the first car control device 41, the second car control device 42, and the third car control device 43 so that the car of the determined assigned car heads toward the floor where the user is waiting, and instructs the appropriate hall destination floor registration device 12 to execute predetermined processing (such as displaying the user ID and displaying information indicating the assigned car).

[0049] The elevator control device 100 also uses the management information 50 to manage information indicating whether the elevator assigned to a user who has registered a call for a destination floor at the landing destination floor registration device 12 of the security gate 10 has responded or not.

[0050] After passing through security gate 10, the user heads to the elevator hall where elevators 21, 22, and 23 are located.

[0051] In step S2, the elevator control device 100 determines whether a call registration for a new destination floor has been made in the elevator hall destination floor registration device 60. If not, the process ends without doing anything. On the other hand, if it has been made, the process proceeds to step S3.

[0052] In step S3, if the elevator control device 100 determines that a call registration for a new destination floor has been made in the elevator hall destination floor registration device 60, it determines whether a call registration for the destination floor of that user already exists and whether the assigned elevator assigned to that user is in an "unresponsive" state. If this is not the case, the process proceeds to step S4. On the other hand, if this is the case, the process proceeds to step S6.

[0053] In step S4, the elevator control device 100 accepts the call registration of a new destination floor and performs the process of allocating the assigned car. Specifically, the elevator control device 100 validly accepts the call registration of the destination floor of the user at the elevator hall destination floor registration device 60, determines the assigned car to be allocated to the user, and controls the appropriate one of the No. 1 car control device 41, No. 2 car control device 42, and No. 3 car control device 43 so that the car of the determined assigned car heads towards the floor where the user is waiting.

[0054] Next, in step S5, the elevator control device 100 instructs the corresponding hall destination floor registration device 60 to perform operations such as displaying the user ID and displaying information indicating the same car number as the assigned car number that has already been assigned.

[0055] On the other hand, in step S6, the elevator control device 100 discards the call registration of the new destination floor. Specifically, the call registration of the destination floor of the user at the hall destination floor registration device 60 in the elevator hall is not accepted and is discarded, thereby invalidating the call registration.

[0056] Next, in step S7, the elevator control device 100 instructs the corresponding hall / destination floor registration device 60 to execute operations such as displaying the user ID and displaying information indicating the newly assigned elevator car number.

[0057] As described above in detail, according to the embodiment, it is possible to prevent the occurrence of unnecessary calls.

[0058] Although the embodiments of the present invention have been described, the above embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
