Description

[Technical field]

[0001] The present invention relates to elevator systems. [Background technology]

[0002] Conventionally, there are elevator systems that allow a user to register a destination floor before getting into the elevator. For example, Patent Document 1 discloses an elevator system in which a destination floor registration device that allows a user to register a destination floor by face recognition is arranged at each landing. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2023-015600 Summary of the Invention [Problem to be solved by the invention]

[0004] In such an elevator system, the destination floor registration device may be provided with a touch panel that displays various information and accepts input. It is conceivable that this touch panel can be used by, for example, elevator maintenance personnel or building managers to configure various settings of the elevator system. In this case, in order to prevent normal users from performing the configuration work, it is necessary to impose restrictions such as providing a dedicated button for configuration work on the screen, making it impossible to display the configuration screen without following a specific operating procedure, providing a physical lock, etc.

[0005] However, when providing dedicated buttons for setting up the screen, there is a risk that unauthorized setting up may be performed if certain operating procedures are leaked. Also, providing dedicated buttons that are not relevant to normal users on the display screen of the touch panel may lead to a decrease in the design of the screen display.

[0006] In addition, when a physical key is provided, there is a risk that the maintenance personnel will forget the key. Also, when multiple maintenance personnel are performing setting work at multiple locations in parallel, each maintenance personnel needs to carry a key, which is also an issue.

[0007] One aspect of the present invention aims to provide an elevator system that allows a user to register a destination floor using facial recognition before boarding the elevator, and that displays worker information on the display unit only for specific workers who are not general users, thereby achieving both convenience and prevention of fraudulent use. [Means for solving the problem]

[0008] In order to solve the above problems, an elevator system according to one embodiment of the present invention is an elevator system that allows a destination floor to be registered before boarding the elevator, and includes an imaging unit that images a user, a display unit that displays information, a face authentication unit that performs face authentication based on the image captured by the imaging unit, a destination floor registration unit that registers the destination floor in accordance with the user when the user identified by face authentication in the face authentication unit is a general user of the elevator, and a worker processing unit that performs processing to display worker information on the display unit that is permitted to be displayed only to the worker when the user identified by face authentication in the face authentication unit is a specific worker who is not a general user.

[0009] According to the above configuration, if the user is determined to be a general user by face authentication, the normal destination floor registration process is performed, whereas if the user is determined to be a specific worker, worker information is displayed on the display unit. Therefore, the worker can display the worker information simply by performing face authentication, and therefore there is no need for a specific operation procedure or for the worker to carry a physical key, improving convenience. In addition, there is no need to provide a dedicated button for setting work on the display screen, which improves the design of the display screen.

[0010] In an elevator system according to another aspect of the present invention, the worker processing unit may perform at least one of the following: processing for changing operation settings in the elevator system, processing for controlling operation in the elevator system, processing for displaying information regarding the status of the elevator system, processing for changing operation settings in the display unit, processing for registering and changing data referenced by the face authentication unit, and processing for displaying information regarding maintenance for the elevator system.

[0011] In an elevator system according to another aspect of the present invention, when the worker information is displayed on the display unit by the worker processing unit, if the worker is not recognized by the face authentication unit, or if a user other than the worker is recognized, the worker processing unit may stop displaying the worker information on the display unit.

[0012] According to the above configuration, the information for the worker is displayed only when the worker is recognized, and when a user other than the worker is recognized, the display of the information for the worker is stopped, thereby preventing persons other than the worker from viewing the information for the worker.

[0013] In an elevator system according to another aspect of the present invention, an imaging display system equipped with the imaging unit and the display unit is installed at multiple locations, and the elevator system may further include a display number limiting unit that limits the number of the display units on which the worker information is simultaneously displayed by the worker processing unit to a predetermined value or less.

[0014] According to the above configuration, the number of display units on which worker information is simultaneously displayed can be limited, thereby preventing the number of simultaneous tasks expected to be performed being exceeded and causing people other than legitimate workers to view worker information on the display units due to erroneous authentication, etc.

[0015] In an elevator system according to another aspect of the present invention, an imaging display system equipped with the imaging unit and the display unit is installed in multiple locations, and when the worker information is displayed simultaneously on multiple display units by the worker processing unit, the worker processing unit may display, on each of the display units, information relating to the other display units on which the worker information is displayed.

[0016] According to the above configuration, since information on the display unit viewed by a worker working at the same time is displayed, the worker viewing the display unit can recognize the location where the other worker is working. Furthermore, if a situation occurs in which a person other than a legitimate worker is authenticated due to erroneous authentication or the like, the legitimate worker can recognize that unnatural authentication is being performed by displaying information on the display unit viewed by the other worker.

[0017] In an elevator system according to another aspect of the present invention, when the worker information is displayed simultaneously on multiple display units by the worker processing unit, the worker processing unit may further display, on each of the display units, information about the worker recognized by the imaging display system including other display units on which the worker information is displayed.

[0018] According to the above configuration, a worker viewing the display unit can recognize the location where other workers are working and information about the workers. In addition, if a situation occurs in which a person other than a legitimate worker is authenticated due to erroneous authentication or the like, the legitimate worker can recognize that unnatural authentication is being performed by displaying information about the other worker.

[0019] An elevator system according to another aspect of the present invention may further include a history recording unit that records, as work history information, worker information about the worker authenticated by facial authentication in the facial authentication unit, and display time information indicating the time at which the worker information was displayed on the display unit by the worker processing unit for the worker.

[0020] According to the above configuration, it is possible to check the status of work performed by a worker based on the work history information.

[0021] In an elevator system according to another aspect of the present invention, multiple types of workers are set, and the worker processing unit may change the content of the worker information to be displayed depending on the type of worker identified by facial recognition in the facial recognition unit.

[0022] According to the above configuration, it is possible to control the display contents to be changed according to the qualifications of the worker, to set the display contents to be used only when a new face recognition system is installed, etc. It is also possible to control the display contents to be different for the elevator system maintenance staff and the building manager.

[0023] The elevator system according to each aspect of the present invention may be realized by a computer. In this case, the control program for the elevator system that realizes the elevator system on a computer by causing the computer to operate as each part (software element) of the elevator system, and the computer-readable recording medium on which the control program is recorded, also fall within the scope of the present invention. Effect of the Invention

[0024] According to one aspect of the present invention, in an elevator system in which the destination floor can be registered using facial recognition before boarding the elevator, it is possible to provide an elevator system that displays worker information on the display unit only for specific workers who are not general users, thereby achieving both convenience and prevention of unauthorized use.

[0025] [Figure 1] FIG. 1 is a schematic diagram showing a configuration example of an elevator system according to a first embodiment of the present invention. [Diagram 2] FIG. 2 is a diagram showing an example of a functional block diagram of the elevator system. [Diagram 3] 4A to 4C are diagrams illustrating an example of a display on a display unit of an imaging display system provided in the elevator system. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] [Embodiment] An embodiment of the present invention will be described in detail below. However, the following description is an example of an elevator system 1 according to the present invention, and the technical scope of the present invention is not limited to the following description and illustrated examples.

[0027] [Elevator System Overview] 1 is a schematic diagram showing a configuration example of an elevator system 1 according to a first embodiment of the present invention. The elevator system 1 is an elevator system capable of registering a destination floor by face recognition, and when a worker performs face recognition by an imaging and display system 40 installed at a hall 60, the system displays information for the worker on the imaging and display system 40, which differs from information displayed to general users.

[0028] When the user identified by face recognition is a general user, the elevator system 1 registers a destination floor according to the user. When the user identified by face recognition is a specific worker who is not a general user, the elevator system 1 displays on the imaging display system 40 worker-only information that is permitted to be displayed only to the worker.

[0029] As a result, the elevator system 1 can display the worker information on the imaging display system 40 simply by the worker performing face authentication. Therefore, the worker does not need to perform a specific operation procedure or bring a physical key in order to display the worker information on the imaging display system 40, and the convenience of the worker can be improved. In addition, since the worker does not need to perform a specific operation procedure in order to display the worker information on the imaging display system 40, for example, the risk of unauthorized setting work being performed due to the leakage of the specific operation procedure can be reduced. As a result, it is possible to realize an elevator system 1 that displays the worker information on the display unit only for the worker while achieving both convenience and prevention of unauthorized use.

[0030] <Elevator system> The elevator system 1 employs a destination floor registration method in which a user registers a destination floor in advance before getting into the elevator car. The elevator system 1 is an elevator system in which a destination floor can be registered by face recognition.

[0031] FIG. 2 is a diagram showing an example of a functional block diagram of the elevator system 1. As shown in FIG. 1 and FIG. 2, the elevator system 1 includes an information processing device 10, elevators 20A and 20B, elevator control panels 21A and 21B, a group management device 30, and imaging display systems 40A to 40D. In the following, the elevators 20A and 20B may be referred to as "elevators 20" without distinction, the elevator control panels 21A and 21B may be referred to as "elevator control panels 21" without distinction, and the imaging display systems 40A to 40D may be referred to as "imaging display systems 40" without distinction. It is assumed that the devices constituting the elevator system 1 are connected to each other via a communication network such as a LAN (Local Area Network), but some of them may be connected to each other via the Internet.

[0032] The elevator system 1 includes an elevator 20A and an elevator 20B. The elevator system 1 may include one elevator 20 or may include more than two elevators 20.

[0033] An elevator control panel 21A and an elevator control panel 21B are provided for the elevator 20A and the elevator 20B, respectively. The elevator control panel 21 controls the operation of the corresponding elevator 20 according to operation control information from the group management device 30. The operation control information will be described in detail later.

[0034] Each elevator control panel 21 transmits operation information of the corresponding elevator 20 to the group management device 30. The operation information includes the current position of the elevator 20 car, the running direction of the car, the opening and closing of the door, the load, and other car conditions.

[0035] Although not shown, elevator control panel 21 includes a control unit and a memory unit. The memory unit stores various programs executed by elevator control panel 21 and data used by the programs. The control unit comprehensively controls each unit of elevator control panel 21. The functions of the control unit may be realized by a CPU (Central Processing Unit) executing the programs stored in the memory unit.

[0036] (Image capture and display system) The imaging display system 40 captures an image of a user's face and displays various information. The imaging display system 40 is installed in a plurality of locations. In this embodiment, as shown in FIG. 1, the imaging display system 40A and the imaging display system 40B are installed in the hall 60A, and the imaging display system 40C and the imaging display system 40D are installed in the hall 60B. Not limited to the above, the imaging display system 40 may be installed, for example, in one entrance hall, or may be installed only in a specific hall 60.

[0037] Each imaging display system 40 includes an imaging section 41, a display section 42, and an input section 43. In Fig. 2, imaging display systems 40A to 40D are shown as imaging display systems 40, but only the imaging section 41A, display section 42A, and input section 43A included in imaging display system 40A are shown, and imaging sections 41B to 41D, display sections 42B to 42D, and input sections 43B to 43D included in imaging display systems 40B to 40D are not shown.

[0038] The imaging unit 41 captures an image of a user. The imaging unit 41 is, for example, a camera. The captured image captured by the imaging unit 41 is transmitted to the information processing device 10. The display unit 42 displays various information. The display unit 42 displays at least information for workers. The display unit 42 performs display under the control of the face authentication unit 112, the destination floor registration unit 312, and the worker processing unit 313, which will be described later.

[0039] The input unit 43 accepts input from a user. The input unit 43 is a touch panel, and is disposed on top of the display unit 42. Therefore, the input unit 43 can be operated on the display surface of the display unit 42. Note that the input unit 43 may be a button instead of a touch panel. Also, the input unit 43 is not essential, and if no input operation is performed in the imaging display system 40, the input unit 43 is not necessary.

[0040] The imaging and display system 40 may be configured to be capable of communicating and calling with the car of the elevator 20 or other imaging and display systems 40 by connecting a smartphone or a headset.

[0041] (Information processing device) The information processing device 10 performs face authentication based on the captured image transmitted from the imaging display system 40, and outputs the face authentication result to the group management device 30. The information processing device 10 includes a control unit 11 and a storage unit 12.

[0042] The control unit 11 comprehensively controls each unit of the information processing device 10. The functions of the control unit 11 may be realized by a CPU executing a program stored in the storage unit 12. The control unit 11 will be described in detail later.

[0043] The storage unit 12 stores various programs executed by the information processing device 10 and data used by the programs. The storage unit 12 also stores user identification information 121.

[0044] Facial data is recorded in the user identification information 121. The facial data is data used in facial authentication of a user. The facial data may be facial image data or facial feature point data, as long as the data can distinguish the face of the user.

[0045] In addition, a default destination floor is linked to the facial data of a general user and recorded in the user identification information 121. The default destination floor is, for example, a floor where each general user is permitted to disembark. Furthermore, in the user identification information 121, a type of worker is linked to the facial data of a specific worker who is not a general user and recorded.

[0046] A plurality of types of workers may be set, and as the types of workers, for example, a maintenance worker, an elevator manager, a building manager, etc. may be set. The registration of such information in the user identification information 121 is performed by, for example, an elevator manager or a building manager who is included in the workers. Note that the user identification information 121 is not limited to the above, and may be stored in an external cloud server (not shown).

[0047] (Control unit of information processing device) The control unit 11 includes an information acquisition unit 111 and a face authentication unit 112. The information acquisition unit 111 acquires various information. The information acquisition unit 111 acquires at least the captured image captured by the imaging unit 41 and the input information input to the input unit 43 from each imaging display system 40.

[0048] The face authentication unit 112 performs face authentication based on the captured image captured by the imaging unit 41. For example, the face authentication is performed by comparing the captured image of the user's face captured by the imaging unit 41 with the face data in the user identification information 121, and identifying which face data in the user identification information 121 the user corresponds to. The face authentication unit 112 also determines whether the identified user is a general user or a worker, and transmits the face authentication result to the group management device 30.

[0049] When the user identified by face authentication is a general user of the elevator 20, the face authentication unit 112 acquires a default destination floor registered in association with the general user from the user identification information 121. The face authentication unit 112 transmits to the group management device 30, as face authentication results, information indicating that the user identified by face authentication is a general user, the acquired default destination floor, the departure floor, and identification information of the imaging display system 40 that captured the image of the user who underwent face authentication. Note that, regarding the departure floor, the floor where the imaging display system 40 that captured the image of the user who underwent face authentication is installed may be set as the departure floor.

[0050] When the identified user is a specific worker and not a general user, the face authentication unit 112 acquires the type of worker registered in association with the worker from the user identification information 121. The face authentication unit 112 transmits to the group management device 30, as face authentication results, information indicating that the user identified by face authentication is a worker, the type of worker, and identification information of the imaging display system 40 that captured the image of the user who performed face authentication.

[0051] (Group control device) The group control device 30 performs overall control of the operation of the elevators 20A and 20B. The group control device 30 also executes destination floor registration or worker processing, and outputs various information and the like to the imaging and display system 40.

[0052] The group management device 30 includes a control unit 31 and a storage unit 32. The control unit 31 comprehensively controls each unit of the group management device 30. The functions of the control unit 31 may be realized by a CPU executing a program stored in the storage unit 32. The control unit 31 will be described in detail later.

[0053] The storage unit 32 stores various programs executed by the group management device 30 and data used by the programs. The storage unit 32 also stores worker type information 321 and work history information 322. The worker type information 321 is information in which the type of worker is associated with the process to be executed. The worker type information 321 may store the type of worker and the worker information to be displayed on the display unit 42 in association with each other. The work history information 322 will be described in detail later. The worker type information 321 and the work history information 322 are not limited to the above, and may be stored in an external cloud server (not shown).

[0054] (Control unit of group management device) The control unit 31 includes an information acquisition unit 311 , a destination floor registration unit 312 , a worker processing unit 313 , a display number limiting unit 314 , and a history recording unit 315 .

[0055] The information acquisition unit 311 acquires various types of information. The information acquisition unit 311 acquires at least the input information input from the imaging display system 40 to the input unit 43, and the face recognition result from the information processing device 10.

[0056] (Destination Floor Registration Section) When a user identified by face authentication in the face authentication unit 112 is a general user of the elevator 20, the destination floor registration unit 312 registers a destination floor according to the user. When a user identified by face authentication in the face authentication unit 112 is a general user of the elevator 20, the destination floor registration unit 312 registers a default destination floor included in the face authentication result as the destination floor of the user.

[0057] In addition, the destination floor registration unit 312 assigns an elevator 20 to a user who has undergone face authentication, based on the departure floor included in the face authentication result, the registered destination floor, and operation information transmitted from the elevator control panel 21. The destination floor registration unit 312 generates operation control information including the departure floor and destination floor used in the assignment of the elevator 20.

[0058] The destination floor registration unit 312 transmits operation control information to the elevator control panel 21 corresponding to the elevator 20 assigned to the registered user. The elevator control panel 21 that has received the operation control information operates the elevator 20 from the departure floor to the destination floor based on the operation control information.

[0059] In addition, the destination floor registration unit 312 creates general user information 50 based on the allocation result of the elevator 20. The general user information 50 includes destination floor information for the face-authenticated user and information for identifying the assigned elevator 20. The destination floor registration unit 312 displays the general user information 50 on the display unit 42 of the imaging display system 40 that images the user who has undergone face authentication.

[0060] Fig. 3 is a diagram showing an example of the display of the display unit 42 of the imaging display system 40. 3001 in Fig. 3 shows a state in which general user information 50 is displayed on the display unit 42. When the user identified by face authentication in the face authentication unit 112 is a general user of the elevator 20, as shown in 3001 in Fig. 3, the destination floor registration unit 312 may display, as general user information 50, a destination floor 51 and the elevator number 52 of the elevator 20 assigned to the general user on the display unit 42.

[0061] In addition, if a user is not identified by facial recognition by the facial recognition unit 112, for example, if the user captured by the imaging unit 41 is a user whose facial data is not registered in the user identification information 121, the destination floor registration unit 312 displays visitor display information on the display unit 42, which is different from the information displayed to general users and the information displayed to workers.

[0062] 3002 in Fig. 3 shows a state in which visitor display information is displayed on the display unit 42. When a user is not identified by face authentication by the face authentication unit 112, the destination floor registration unit 312 may display, as visitor display information, destination floor information 53, in which a destination floor of a car can be input, on the display unit 42, as shown in 3002 in Fig. 3 .

[0063] In this way, for a user whose face data is not registered, the destination floor may be registered by operating the destination floor information 53. Also, in the imaging display system 40, the visitor display information may be displayed as a normal screen before the face authentication unit 112 is performed. This allows visitors and the like to use the elevator system 1. Note that in the case of a building in which visitors and the like do not use the elevator 20, it is not essential to display the visitor display information.

[0064] (Worker treatment area) When the user identified by face authentication in the face authentication unit 112 is a specific worker and not a general user, the worker processing unit 313 performs processing to display on the display unit 42 worker information that is permitted to be displayed only to that worker.

[0065] As a result, if the user is determined to be a general user by face authentication, the normal destination floor registration process is performed, whereas if the user is determined to be a specific worker, worker information is displayed on the display unit 42. Therefore, the worker can display the worker information on the display unit 42 simply by performing face authentication, and therefore there is no need for the worker to perform a specific operation procedure or to carry a physical key, improving the convenience of the worker. In addition, there is no need to provide a dedicated button for setting work on the display screen, which improves the design of the display screen.

[0066] The worker processing unit 313 executes one of the following processes when the user identified by the face authentication by the face authentication unit 112 is a specific worker and not a general user. That is, in the above case, the worker processing unit 313 executes at least one of a process of changing the operation settings in the elevator system 1, a process of controlling the operation in the elevator system 1, a process of displaying information on the status of the elevator system 1, a process of changing the operation settings in the display unit 42, a process of registering and changing data referenced by the face authentication unit 112, and a process of displaying information on maintenance for the elevator system 1.

[0067] The worker processing unit 313 determines the process to be executed by, for example, referring to the worker type information 321. As an example, a case where the worker processing unit 313 performs a display process of information related to the maintenance of the elevator system 1 will be described. 3003 in FIG. 3 shows a state where the information 54 related to the maintenance of the elevator system 1 is displayed on the display unit 42. As shown in 3003 in FIG. 3, the worker processing unit 313 performs the display process by displaying the information related to the maintenance of the elevator system 1 as worker information on the display unit 42. Note that, when a worker registers a destination floor to perform maintenance, the worker processing unit 313 may further display 3002 in FIG. 3 on the display unit 42. The processes that the worker processing unit 313 can perform will be described in detail later.

[0068] When the worker information is being displayed on the display unit 42 by the worker processing unit 313, if the worker is not recognized by the face authentication unit 112 or if a user other than the worker is recognized, the worker processing unit 313 stops displaying the worker information on the display unit 42.

[0069] For example, during a display period in which worker information is displayed on the display unit 42A, the elevator system 1 captures images at predetermined intervals using the imaging unit 41A of the imaging display system 40A equipped with the display unit 42A, and continues face authentication using the captured images in the face authentication unit 112.

[0070] If, during the above-mentioned display period, a worker is not recognized in the image captured by the imaging unit 41A, the worker processing unit 313 stops displaying the worker information on the display unit 42. Alternatively, if, during the above-mentioned display period, a user other than a worker (e.g., a general user) is recognized in the image captured by the imaging unit 41A, the worker processing unit 313 stops displaying the worker information on the display unit 42.

[0071] As a result, the information for the worker is displayed only when the worker is recognized, and if a user other than the worker is recognized, the display of the information for the worker is stopped, thereby preventing persons other than the worker from viewing the information for the worker.

[0072] In addition, the worker processing unit 313 may stop displaying the worker information on the display unit 42 if a state in which the worker is not recognized by the face authentication unit 112 continues for a predetermined period of time or more during a display period in which the worker information is being displayed on the display unit 42 by the worker processing unit 313.

[0073] Furthermore, the worker processing unit 313 may stop the display of the worker information on the display unit 42 if there is no input operation by the input unit 43 for a predetermined period of time or longer during a display period in which the worker information is being displayed on the display unit 42 by the worker processing unit 313. Furthermore, the worker processing unit 313 may stop the display of the worker information on the display unit 42 if a predetermined operation (e.g., touching the "Exit" button) is performed by the input unit 43 during a display period in which the worker information is being displayed on the display unit 42 by the worker processing unit 313, or if an abnormality occurs in communication between the devices constituting the elevator system 1.

[0074] When worker information is displayed simultaneously on multiple display units 42 by the worker processing unit 313, the worker processing unit 313 displays, on each of the display units 42, information regarding the other display units 42 on which the worker information is being displayed.

[0075] 1, when face authentication of a worker is performed from images captured by the imaging display system 40A and the imaging display system 40C, worker information is simultaneously displayed on the display unit 42A and the display unit 42C. At this time, the worker processing unit 313 displays information related to the display unit 42C (for example, the name of the display unit 42C) on the display unit 42A, and displays information related to the display unit 42A on the display unit 42C.

[0076] As a result, information about the display unit 42 viewed by workers working at the same time is displayed on each display unit 42, so that the worker viewing the display unit 42 can recognize where the other worker is working. Furthermore, if a situation occurs in which a person other than the authorized worker is authenticated due to erroneous authentication or the like, information about the display unit 42 viewed by the other worker is displayed on the display unit 42 where the authorized worker is working, so that the authorized worker can recognize that unnatural authentication is being performed.

[0077] When the worker information is displayed simultaneously on multiple display units 42 by the worker processing unit 313, the worker processing unit 313 further displays, on each of the display units 42, information about the worker recognized by the imaging display system 40 that has other display units 42 on which the worker information is displayed.

[0078] 1, when face recognition of a worker is performed from images captured by the imaging display system 40A and the imaging display system 40C, worker information is simultaneously displayed on the display unit 42A and the display unit 42C. At this time, the worker processing unit 313 displays information about the worker recognized from the images captured by the imaging display system 40C (e.g., the name of the worker) on the display unit 42A, and displays information about the worker recognized from the images captured by the imaging display system 40A on the display unit 42C.

[0079] This allows a worker viewing the display unit 42 to recognize the location where the other worker is working and information about that worker. Furthermore, if a situation occurs in which a person other than the authorized worker is authenticated due to erroneous authentication or the like, information about the other worker is displayed on the display unit 42 where the authorized worker is working, allowing the authorized worker to recognize that unnatural authentication is being performed.

[0080] (Display number limit section) The display number limiting unit 314 limits the number of display units 42 on which worker information is simultaneously displayed by the worker processing unit 313 to a predetermined value or less. For example, when the predetermined value is set to "2," it is assumed that the users of the images captured by the imaging display system 40A, the imaging display system 40B, and the imaging display system 40C are identified as workers by the face authentication by the face authentication unit 112. In this case, the display number limiting unit 314 limits the targets on which worker information is displayed to only two devices, for example, the imaging display system 40A and the imaging display system 40B, and does not display the information on the imaging display system 40C.

[0081] This makes it possible to limit the number of display units 42 on which worker information is simultaneously displayed, thereby preventing the number of workers exceeding the expected number of simultaneous operations from being exceeded, and preventing unauthorized workers from viewing the worker information on the display units 42 due to erroneous authentication or the like. The predetermined value may be set based on, for example, the number of workers working simultaneously.

[0082] The history recording unit 315 records, as work history information 322, worker information about a worker authenticated by face authentication in the face authentication unit 112 and display time information indicating the time when the worker information was displayed on the display unit 42 by the worker processing unit 313 for that worker. The worker information includes, for example, the name and type of worker. This makes it possible to check the status of work performed by the worker from the work history information 322.

[0083] (Processing performed by the worker processing unit) As described above, the worker processing unit 313 executes at least one of the following: processing for changing operation settings in the elevator system 1, processing for controlling operation in the elevator system 1, processing for displaying information on the status of the elevator system 1, processing for changing operation settings in the display unit 42, processing for registering and changing data referenced by the face authentication unit 112, and processing for displaying information on maintenance of the elevator system 1. Processing other than the processing for displaying information on maintenance of the elevator system 1 that can be executed by the worker processing unit 313 described above will be described below.

[0084] The worker processing unit 313 may display a setting change screen for setting the operation of the elevator system 1 on the display unit 42 as worker information, and may perform setting change processing for the operation of the elevator system 1 based on information input to the input unit 43. The setting change processing for the operation of the elevator system 1 may be, for example, changing the ON / OFF of the fan in the car, and changing the operation mode of the car. The operation mode of the car may be, for example, a maintenance mode, a normal mode, a controlled operation mode, etc. The change may be performed individually or collectively for the multiple elevators 20.

[0085] The worker processing unit 313 may display a control screen for controlling the operation of the elevator system 1 on the display unit 42 as worker information, and perform control processing for the operation of the elevator system 1 based on the information input to the input unit 43. The control processing for controlling the operation of the elevator system 1 includes, for example, control for stopping a specific elevator 20 at a hall 60 where the imaging display system 40 is located where the worker information is displayed, and control for stopping a specific elevator 20 at any floor.

[0086] The worker processing unit 313 may perform display processing of information regarding the status of the elevator system 1, such as displaying information regarding the status of the elevator system 1 on the display unit 42 as worker information. The display processing includes, for example, displaying the status of a specific elevator 20 (car position, number of passengers, weight, operating direction, and operating mode) and a video (or recorded video) of the inside of the car of the specific elevator 20 on the display unit 42.

[0087] The worker processing unit 313 may display a setting change screen for changing the settings of the operation on the display unit 42 as worker information on the display unit 42, and perform setting change processing for the operation on the display unit 42 based on the information input to the input unit 43. The setting change processing for the operation on the display unit 42 includes, for example, adjustment of the volume, brightness, and screen of the imaging display system 40.

[0088] The worker processing unit 313 may display on the display unit 42 a registration / change processing screen for the user identification information 121 referenced by the face authentication unit 112 as worker information, and perform registration / change processing of the data referenced by the face authentication unit 112 based on information input to the input unit 43.

[0089] In addition, the worker processing unit 313 may display a two-dimensional code that enables access to maintenance data as worker information, and may also display handover information from past maintenance, memorandums, work history information 322, various event codes, etc.

[0090] Furthermore, the worker processing unit 313 may change the contents of the worker information to be displayed and the contents of the processing depending on the type of worker identified by face recognition in the face recognition unit 112. This enables control to change the display contents according to the qualifications of the worker, control to provide display contents to be used only when a new face recognition system is installed, etc. Also, it becomes possible to control to display different contents for the maintenance staff of the elevator system 1 and the building manager.

[0091] In the present embodiment, a configuration has been described in which the face authentication unit 112 is provided in an information processing device 10 different from the group management device 30, and the face authentication process is executed outside the group management device 30. However, the present invention is not limited to this configuration, and for example, the group management device 30 may have a face authentication processing function without providing an information processing device 10. Furthermore, each of the face authentication unit 112, the destination floor registration unit 312, the worker processing unit 313, the display number limiting unit 314, and the history recording unit 315 may be provided in either the group management device 30 or the information processing device 10, or may be provided in an external server.
