Description

Technical Field

[0001] Embodiments of the present invention relate to an elevator control device, an elevator control system, and an elevator control method.

Background Art

[0002] In recent elevator control systems, an autonomous mobile body such as a robot is made to ride in an elevator car to perform various operations, and autonomous mobile body operation such as moving to a destination floor (target floor) is performed.

[0003] In the prior art, when the destination floor of the autonomous mobile body is a security floor where the entry of general users is restricted and only specific persons can enter, when there is no general user riding in the car, and only when the autonomous mobile body rides in the car alone, it is permitted to keep the door open on the security floor to suppress the entry of general users to the security floor.

[0004] However, since the elevator is also used by general users, when the elevator is used for the autonomous mobile body to enter the security floor, there may be a situation where a general user rides in the car together. At that time, if the car lands on the security floor, which is the destination floor of the autonomous mobile body, before the destination floor of the general user, the general user can get off at the security floor, resulting in security problems.

[0005] To solve such problems, in the prior art, control is performed to register a destination floor call to the security floor only when there is no general user riding in the car, or when a general user rides in the car, the destination floor call of the general user is prioritized, and after the general user gets off, the elevator responds to the destination floor call of the autonomous mobile body to the security floor.

[0010] The embodiments will be described below with reference to the drawings.

[0011] (First embodiment) FIG. 1 is a diagram showing an example of the overall configuration of an elevator control system 1 according to the first embodiment. As shown in FIG. 1, the elevator control system 1 of the present embodiment mainly includes control panels 100A and 100B provided for each of a plurality of elevators 2A and 2B, controllers 150A and 150B provided for each of the plurality of elevators 2A and 2B, a security system 161 provided in a control room 160, a server 210 in an elevator hoistway 200, a server 310 in a robot cloud 300, a monitoring center 400, and an elevator company 700.

[0012] In the present embodiment, a plurality of elevators 2A and 2B are installed in a building 3 (an example of a building) such as an apartment building. In the example of FIG. 1, two elevators 2A and 2B are illustrated, but it may be configured to have only one elevator or three or more elevators.

[0013] Each of the elevators 2A and 2B includes carriages 50A and 50B in respective hoistways 20A and 20B. In addition, each hoistway 20A and 20B includes a hoisting machine and a counterweight, not shown. The carriages 50A and 50B and the counterweight are respectively supported to be movable up and down on a pair of guide rails, not shown, erected in the hoistways 20A and 20B, and move up and down via ropes.

[0014] In addition to the user 5A, robots 500A, 500B, and 500C as autonomous mobile bodies can also board the carriages 50A and 50B.

[0015] The carriages 50A and 50B are provided with operation panels 4A and 4B, cameras 7A and 7B, load sensors 8A and 8B, and human sensors 12A and 12B. The operation panels 4A and 4B receive various operations from users in the carriages 50A and 50B and also provide various notifications to the carriages 50. The operation panels 4A and 4B are connected to the control panels 100A and 100B by wire or wirelessly.

[0016] FIG. 2 is a diagram showing an example of the configuration of the operation panels 4A and 4B inside the car 50 according to the first embodiment. As shown in FIG. 2, a plurality of push buttons 413 and two opening / closing push buttons 414 are provided at the central portions of the operation panels 4A and 4B.

[0017] Each of the plurality of push buttons 413 is assigned a floor number. By pressing the push button 413 corresponding to the floor number of the destination floor desired by the user, a destination floor call is transmitted from the operation panels 4A and 4B to the control panels 100A and 100B.

[0018] One of the two opening / closing push buttons 414 is a button for giving an instruction to open the doors of the cars 50A and 50B when pressed by the user. The other of the two opening / closing push buttons 414 is a button for giving an instruction to close the doors of the cars 50A and 50B when pressed by the user. Here, opening the door may be referred to as "door open", and closing the door may be referred to as "door close".

[0019] Here, a destination floor call is a request (operation data) made by a user inside the car 50 to make the car 50 go to a desired destination floor. The destination floor is specified in the destination floor call.

[0020] Also, in the present embodiment, a destination floor call for the robot is transmitted from the server 210 in the elevator penthouse 200 to the control panel 100 via the controller 150. The destination floor call for the robot specifies the robot ID of the robot 500 that wishes to use the elevator 2, the departure floor, and the destination floor (also referred to as the target floor), and is operation data for moving the car 50 to the specified departure floor and making it go from the departure floor to the specified destination floor.

[0021] Note that, together with the push buttons 413 and the opening / closing push buttons 414, or instead of the push buttons 413 and the opening / closing push buttons 414, a non-contact sensor may be provided on the operation panels 4A and 4B.

[0022] As shown in Figure 2, a liquid crystal display unit 411 and a speaker 412 are provided at the top of the control panels 4A and 4B. The liquid crystal display unit 411 is a display device that displays various information in response to instructions from control panels 100A, 100B, etc. In the example in Figure 2, the liquid crystal display unit 411 displays an upward arrow indicating that elevator cars 50A and 50B are ascending, and the number "3" indicating that they are currently passing the 3rd floor.

[0023] Speaker 412 outputs various audio signals based on instructions from control panels 100A, 100B, etc.

[0024] Furthermore, as shown in Figure 2, a card reader 415 is provided at the bottom of the control panels 4A and 4B. The card reader 415 reads information from IC cards or smartphones held by users via proximity communication and transmits the read information to the control panels 100A, 100B, etc.

[0025] Returning to Figure 1, cameras 7A and 7B inside elevator cars 50A and 50B photograph the interior of elevator cars 50A and 50B and send the captured images to control panels 100A and 100B. Also, when the doors of elevator cars 50A and 50B are open at landing 25, cameras 7A and 7B are able to photograph the landing and send the captured images to control panels 100A and 100B.

[0026] Load sensors 8A and 8B are installed on the bottom of the elevator cars 50A and 50B and detect the weight of the elevator car 50. If a user 5A or robots 500A and 500B are inside the elevator car 50A and 50B, load sensors 8A and 8B detect the weight of the elevator car 50 itself, plus the weight of the user 5A and the robots 500A and 500B. Load sensors 8A and 8B send the detected weight as a detection signal to the control panels 100A and 100B.

[0027] The motion sensors 12A and 12B are installed on the ceiling of the elevator cars 50A and 50B. They detect the presence of users (people) inside the elevator cars 50A and 50B and send detection signals to the control panels 100A and 100B.

[0028] Platform 25 is located on each floor. Platform 25 is where users and robots 500 wait for the arrival of elevator cars 50A and 50B of elevators 2A and 2B. As shown in Figure 1, the landing 25 is equipped with a camera 9 and a lighting device 13. The camera 9 is mounted on the wall next to the door (not shown) that serves as the entrance and exit for the elevator car 50, and captures images of the situation at the landing 25, including users waiting there. The lighting device 13 is mounted on the ceiling of the landing 25 and illuminates the landing 25. A control panel (not shown) is also provided at the landing 25. Users can call for a landing from the control panel.

[0029] Here, a boarding call is a request (operation data) made by a boarding user to have a train car 50 traveling in either an up or down direction arrive at that boarding location. The boarding call specifies the destination direction and the floor from which the boarding call was made (i.e., the departure floor). The camera 9, lighting device 13, and control panel are connected to control panels 100A and 100B by wire or wireless connection.

[0030] Inside each of the elevator shafts 20A and 20B, control panels 100A and 100B and controllers 150A and 150B are installed. Control panels 100A and 100B are connected wirelessly or via wire to the operation panels 4A and 4B installed in the elevator cars 50A and 50B.

[0031] Control panels 100A and 100B control the operation of elevator cars 50A and 50B within elevators 2A and 2B, respectively. Control panels 100A and 100B are connected to controllers 150A and 150B, respectively, by wired or wireless connection. Details of control panels 100A and 100B will be described later.

[0032] Controllers 150A and 150B are connected via a network to server 210 in the elevator cloud 200. Controllers 150A and 150B are intermediary devices equipped with interface and hub functions to control communication between control panels 100A and 100B and server 210, and to mediate various signals exchanged between control panels 100A and 100B and server 210. Controllers 150A and 150B are configured as computers equipped with a CPU, ROM, RAM, etc.

[0033] Control room 160 is where the building manager and other personnel of Building 3 are stationed. Security system 161 is installed in control room 160. The security system 161 is configured as a computer with a CPU, ROM, RAM, etc., and is capable of communicating with robots 500A and 500B, control panels 100A and 100B, etc. The security system 161 performs various security-related processes.

[0034] The security system 161 receives requests from control panels 100A and 100B for personnel to monitor the disembarkation of the robot 500 from its car 50 on the security floor. Upon receiving such a request, the security system dispatches personnel to the security floor to monitor the disembarkation of the robot from its car 50A and 50B. Here, a security floor is a floor where entry for general users is restricted and only specific individuals are allowed to enter.

[0035] The building manager and other personnel in control room 160 give various instructions to control panels 100A and 100B. In addition, the manager of control room 160 receives various instructions from control panels 100A and 100B via email or other means through a PC or terminal device.

[0036] Server 210 in the elevator cloud 200 issues various control instructions to control panels 100A and 100B via controllers 150A and 150B for elevator cars 50A and 50B of elevators 2A and 2B, and also receives various instructions and data from control panels 100A and 100B via controllers 150A and 150B. Server 210 in the elevator cloud 200 is connected via the network to the monitoring center 400 (internal server) and server 310 in the robot cloud 300.

[0037] The monitoring center 400 houses an internal server (not shown). This internal server is located within an affiliated company of elevator 11 and collects information necessary for the maintenance and remote monitoring of elevator 2 from elevators 2A and 2B. This allows maintenance personnel to address any malfunctions in elevators 2A and 2B by referencing the maintenance information collected on the internal server at the monitoring center 400. Furthermore, when functions and services are executed via the elevator cloud 200, it is possible to access the internal server at the monitoring center 400 as needed to access building and elevator information, and for maintenance personnel to obtain information necessary for elevator management.

[0038] The server 310 of the robot cloud 300 receives various instructions and data from the server 210 of the elevator cloud 200. The server 310 of the robot cloud 300 is connected via a network to multiple robots 500A, 500B, and 500C within building 3, and sends various instructions to each of the multiple robots 500A, 500B, and 500C. Details regarding the server 210 of the elevator cloud 200 and the server 310 of the robot cloud 300 will be described later.

[0039] Elevator Company 700 is a company that provides elevator 2, and within Elevator Company 700, there is a server 710.

[0040] Server 710 stores the signal exchanges between it and Server 210 of the elevator cloud 200, between it and Server 310 of the robot cloud 300, between Server 210 of the elevator cloud 200 and Server 310 of the robot cloud 300, between Server 210 of the elevator cloud 200 and the control panel 100, and between Server 210 of the elevator cloud 200 and the security system 161 and monitoring center 400 of the control room 100 that manages Building 3. In other words, it behaves like a mirror server for Server 210 of the elevator cloud 200. Server 710 also has the function of storing error notifications between each of these devices.

[0041] The number of elevators is not limited, and there are three or more elevators in Building 3. Therefore, the number of hoistways 20A, 20B, elevator cars 50A, 50B, control panels 100A, 100B, and controllers 150A, 150B will also vary according to the number of elevators 2A, 2B. Here, if we do not distinguish between multiple elevators 2A, 2B, multiple hoistways 20A, 20B, multiple elevator cars 50A, 50B, multiple control panels 100A, 100B, and multiple controllers 150A, 150B, we will refer to them as elevator 2, hoistway 20, elevator car 50, control panel 100, and controller 150. If we do not distinguish between control panels 4A, 4B, cameras 7A, 7B, load sensors 8A, 8B, and motion sensors 12A, 12B, we will refer to them as control panel 4, camera 7, load sensor 8, and motion sensor 12.

[0042] Next, we will describe the details of the control panel 100. Figure 3 is a block diagram showing an example of the functional configuration of a control panel 100 according to the first embodiment. The control panel 100 is an example of an elevator control device.

[0043] The control panel 100 has a typical computer configuration and, as shown in Figure 3, mainly comprises a control unit 120, a communication unit 102, a passenger detection unit 123, a suppression processing unit 124, a door control unit 125, and a storage unit 110.

[0044] Furthermore, as shown in Figure 3, the control panel 100 is connected by wire or wireless to the load sensor 8, the camera 7 inside the elevator car 50, the camera 9 at the landing 25, the motion sensor 12, and the lighting device 13 at the landing 25. The load sensor 8 (8A, 8B) is installed in the elevator car 50 as described above. The camera 7 is installed near the ceiling of the elevator car 50 so as to be able to capture images of the inside of the elevator car 50 and, when the doors of the elevator car 50 are open, the landing.

[0045] The storage unit 110 is a storage medium (i.e., a memory device) such as ROM or RAM. The storage unit 110 stores a management database 111 (hereinafter referred to as "management DB 111").

[0046] The management DB 111 is a database containing various data necessary for using elevator 2. For example, the management DB 111 registers the robot IDs of robots 500 that can ride elevator 2 controlled by the control panel 100. Here, the robot ID is information used to identify robot 500.

[0047] The memory unit 110 also stores a robot boarding flag. The robot boarding flag indicates whether or not robot 500 is in the elevator car 50. When the robot boarding flag is on, it indicates that robot 500 is in the elevator car 50. When the robot boarding flag is off, it indicates that robot 500 is not in the elevator car 50.

[0048] Furthermore, the memory unit 110 stores the boarding mode. The boarding mode indicates whether or not a user and a robot are riding together in the elevator car 50. If both are riding together, the boarding mode is set to "boarding mode". If neither is riding together, nothing is set in the boarding mode.

[0049] The communication unit 102 consists of a communication device having a predetermined communication protocol and performs communication processing between the control panel 100 and the controller 150. Specifically, the communication unit 102 sends and receives various data with other control panels 100 and the server 210 of the elevator cloud 200 via the controller 150. The communication unit 102 also sends and receives various instructions and notifications with the administrator's mobile terminal or PC in the control room 160.

[0050] In this embodiment, the communication unit 102 receives destination floor calls and destination floor calls for the robot from the server 210 of the elevator cloud 200 via the controller 150. The communication unit 102 also receives information for security deactivation, which has been analyzed from the two-dimensional code by the robot 500, from the server 210 of the elevator cloud 200 via the controller 150.

[0051] The control unit 120 consists of a hardware processor (CPU). As shown in Figure 2, the control unit 120 mainly comprises a normal operation control unit 121 and a robot-linked operation control unit 122.

[0052] The normal operation control unit 121 controls normal operation. Normal operation refers to operation in which only people are riding in the elevator car 50, without any robots accompanying them. The normal operation control unit 121 performs group management control of the elevator cars 50.

[0053] Here, group control refers to a control system that assigns the elevator car 50 closest to the departure floor, such as the floor from which the elevator car 50 was called. In this embodiment, the normal operation control unit 121 performs group control by coordinating with the control panel 100 of another elevator 2, for example, by querying the control panel 100 of another elevator 2 for the departure floor, the current position and status of the elevator car 50, and receiving the response.

[0054] The robot-linked operation control unit 122 controls the robot-linked operation. Robot-linked operation refers to operation in which robot 500 rides in elevator car 50. Robot-linked operation can be divided into two types: robot-only operation, where no human passengers ride in elevator car 50, and non-robot-only operation, where humans can ride in elevator car 50. Robot-linked operation is sometimes simply referred to as robot operation.

[0055] In this embodiment, when the communication unit 102 receives a destination floor call for the robot, specifying the security floor as the destination floor for the robot 500, the robot-linked operation control unit 122 registers the destination floor call for the robot in the storage unit 110, etc., places the robot 500 into the elevator car 50, and moves the elevator car 50 to the security floor.

[0056] Furthermore, when the riding mode, as described later, is the passenger mode, the robot-linked operation control unit 122 receives a destination floor call from a user that specifies a security floor as the destination floor along with input of a predetermined security release operation, and determines whether the security floor specified in the destination floor call matches the security floor specified in the robot's destination floor call. If they match, the unit determines that the user who made the destination floor call is a specific person authorized to enter the security floor and cancels the passenger mode.

[0057] Examples of predetermined security release operations include pressing multiple predetermined push buttons 413 and open / close push buttons 414 on the control panel 4 in combination, or touching an IC card or the like to the card reader 415. In addition, predetermined operations on the robot 500 (for example, scanning a two-dimensional code) or operations from outside the elevator car 50 (for example, operations from the control panel at the landing 25) can also be used as security release operations.

[0058] Furthermore, if the destination floor specified in the robot's destination floor call is the security floor, the robot-linked operation control unit 122 instructs the control panel 4 inside the elevator car 50 not to display the security floor.

[0059] The passenger determination unit 123 determines whether the robot 500 and a user are riding together in the elevator car 50. Specifically, the passenger determination unit 123 determines that the robot 500 and a user are riding together in the elevator car 50 if the total load of the elevator car 50 indicated by the detection signal from the load sensor 8 is greater than the sum of a predetermined load of the elevator car 50 itself and a predetermined load of the robot 500. Alternatively, the passenger determination unit 123 determines that the robot 500 and a user are riding together in the elevator car 50 if a user is visible in the captured image taken inside the elevator car 50 by the camera 7, that is, by analyzing the captured image. Alternatively, the passenger determination unit 123 determines that the robot 500 and a user are riding together in the elevator car 50 if a person is detected by the detection signal from the human presence sensor 12. However, the methods for determining whether someone is a passenger are not limited to these.

[0060] Furthermore, if the passenger detection unit 123 determines that the robot 500 and the user are riding together in the elevator car 50, it sets the riding mode to passenger mode. Furthermore, the passenger detection unit will deactivate the passenger mode if the robot 500 disembarks from the elevator car 50 at the security floor, or if it determines that all passengers have disembarked from the elevator car 50 before the elevator car 50 arrives at the security floor.

[0061] Furthermore, the passenger determination unit 123 determines whether the robot 500 is currently in the elevator car 50 or is disembarking from the elevator car 50 using the aforementioned method with the load sensor 8 and camera 7.

[0062] The suppression processing unit 124 executes a suppression process to prevent users from disembarking at the security floor when the boarding mode is the passenger boarding mode and the elevator car 50 carrying the robot 500 arrives at the security floor.

[0063] The suppression processing unit 124 outputs a warning message inside the elevator car 50 as part of its suppression process. For example, the suppression processing unit 124 outputs a warning message from the speaker 412 on the control panel 4 inside the elevator car 50 stating that it is a security floor and general users cannot enter. Alternatively, a similar message can be displayed on the liquid crystal display 411 of the control panel 4.

[0064] When the elevator car 50 carrying the robot 500 arrives at the security floor, or when the elevator car 50 carrying the robot 500 slows down as it approaches the security floor, the suppression processing unit 124 reduces the illuminance of the lighting device 13 installed at the landing 25 on the security floor as a suppression process.

[0065] The suppression processing unit 124, as part of the suppression process, sends a request to the security system 161 in the control room 160 to monitor the disembarkation of the robot 500 from the elevator car 50 on the security floor by the relevant personnel.

[0066] The suppression processing performed by the suppression processing unit 124 as described above is a process to alert general users of the elevator car 50 not to disembark from the elevator car 50 at the security floor, in other words, to alert general users not to enter the security floor, and these suppression processes are referred to as alert activation operations.

[0067] The door control unit 125 controls the opening and closing of the doors of the elevator car 50. Here, opening the doors is referred to as "door opening," and closing the doors is referred to as "door closing."

[0068] Next, we will describe the details of server 210 within the elevator cloud 200. Figure 4 is a block diagram showing an example of the functional configuration of a server 210 in the elevator cloud 200 according to the first embodiment. As shown in Figure 4, the server 210 mainly comprises a control unit 211, a communication unit 212, and a storage unit 220, as is typical for a computer.

[0069] The memory unit 220 is, for example, a storage medium (memory device) such as ROM or RAM. Various programs are stored in the memory unit 220.

[0070] The communication unit 212 consists of a communication device having a predetermined communication protocol and performs communication processing between the server 210 and the controller 150 of the control panel 100, and communication processing between the server 210 and the server 310 in the robot cloud 300.

[0071] In this embodiment, the communication unit 212 receives a request from the server 310 of the robot cloud 300 for the robot 500 to move to the security floor. The communication unit 212 also transmits to the control panel 100 a destination floor call, a destination floor call for the robot, and a landing call including the destination floor, which are generated by the control unit 211 described later.

[0072] The control unit 211 consists of a hardware processor (CPU). The control unit 211 generates a destination floor call for the robot, specifying the security floor as the destination floor and the departure floor, based on the request for the robot 500 to move to the security floor received by the communication unit 212. Here, the departure floor can be the base floor.

[0073] Next, we will describe the details of server 310 within robot cloud 300. Figure 5 is a block diagram showing an example of the functional configuration of a server 310 in a robot cloud 300 according to the first embodiment. As shown in Figure 5, the server 310 mainly comprises a control unit 311, a communication unit 312, and a storage unit 320, as is typical for a computer.

[0074] The memory unit 320 is a storage medium (memory device) such as ROM or RAM. Various programs are stored in the memory unit 320.

[0075] The communication unit 312 consists of a communication device having a predetermined communication protocol and performs communication processing between the server 310 and the server 210 in the elevator cloud 200, as well as communication processing between the server 310 and the robot 500.

[0076] In this embodiment, the communication unit 312 receives a request from the robot 500 to move to the security floor, along with the robot ID, and transmits the received request to move to the security floor to the server 210 of the elevator cloud 200.

[0077] The control unit 311 consists of a hardware processor (CPU). The control unit 311 controls various processes related to the robot 500.

[0078] Next, we will explain the details of Robot 500. Figure 6 is a block diagram showing an example of the functional configuration of a robot 500 according to the first embodiment. As shown in Figure 6, the robot 500 mainly comprises a camera 506, a two-dimensional code reader 507, various sensors 505, a control unit 501, an input unit 508, a communication unit 502, a travel control unit 509, a drive unit 503, and a storage unit 510.

[0079] The camera 506 captures images of the area around the robot 500 and transmits the captured images to the server 310 of the robot cloud 300. The robot 500 may also be configured to transmit the captured images to the control panel 100.

[0080] The two-dimensional code reader 507 is a device that reads two-dimensional codes brought close to the user, a designated person, or personnel in the control room 160.

[0081] The various sensors 505 include, for example, motion sensors, acceleration sensors, and load sensors, but are not limited to these.

[0082] The memory unit 510 is, for example, a storage medium (memory device) such as ROM or RAM. Various programs are stored in the memory unit 510.

[0083] The input unit 508 takes the two-dimensional code read by the two-dimensional code reader 507 as input and analyzes it.

[0084] The communication unit 502 consists of a communication device having a predetermined communication protocol and performs communication processing between the robot 500 and the server 310 in the robot cloud 300. In this embodiment, the communication unit 502 sends a request to move to the security floor to the server 310 of the robot cloud 300.

[0085] The control unit 501 consists of a hardware processor (CPU). When the elevator 2 is in operation, the control unit 501 reads and executes various programs from the memory unit 510, thereby performing various operations on the elevator 2.

[0086] The drive unit 503 is a motor or the like that drives the robot 500 to make it move. The travel control unit 509 controls the drive unit 503 to control the movement of the robot 500.

[0087] The above configuration of the robot 500 is just one example, and it may also be further equipped with an audio output unit such as a speaker and an input unit such as a touch panel.

[0088] Next, the elevator control process performed by the elevator control system 1 of this embodiment, configured as described above, will be explained. Figure 7 is a sequence diagram showing an example of the overall flow of the elevator control process according to the first embodiment.

[0089] First, the communication unit 502 of robot 500 sends a request to move to the security floor to the server 310 of the robot cloud 300 (S11). After that, robot 500 moves to the departure floor.

[0090] In the robot cloud 300, the server 310 receives a request from the robot 500 to move to the security floor, and transmits the received request to the elevator cloud 200 server 210 (S12).

[0091] In the elevator cloud 200 server 210, when the communication unit 212 receives a request to move to the security floor from the robot cloud 300 server 310, the control unit 211 generates a destination floor call for the robot, specifying the security floor as the destination floor and the departure floor, based on the received request to move to the security floor (S13). Then, the communication unit 212 transmits the generated destination floor call for the robot to the control panel 100 (S14).

[0092] In the control panel 100, when the communication unit 102 receives a destination floor call for the robot via the controller 150, the robot-linked operation control unit 122, in cooperation with other elevators 2, performs group control to assign the elevator car 50 (S15). Then, the robot-linked operation control unit 122 of the control panel 100, which manages the assigned elevator car 50, moves the assigned elevator car 50 to the departure floor specified by the destination floor call for the robot (S16). When the elevator car arrives at the departure floor, the door control unit 125 opens the doors of the elevator car 50 (S17). Robot 500 boards the open elevator car 50 (S18).

[0093] When the robot 500 boards the elevator car 50, the door control unit 125 in the control panel 100 determines that the robot 500 has boarded based on the change in load from the load sensor 8, and closes the door (S19).

[0094] Next, in the control panel 100, the robot-linked operation control unit 122 moves the elevator car 50 to the security floor designated as the destination floor (S20). Then, when the elevator car 50 arrives at the security floor, the control panel 100 executes a disembarkation suppression process (S21).

[0095] Subsequently, robot 500 disembarks from elevator car 50 and enters the security floor (S22).

[0096] Here, we will explain the details of the disembarkation control process in S21. Figures 8 and 9 are flowcharts showing an example of the procedure for the disembarkation suppression process according to the first embodiment. First, the passenger determination unit 123 of the control panel 100 determines whether or not the robot 500 is riding in the elevator car 50 based on the load of the elevator car 50, etc. (S101). If the robot 500 is not riding in the elevator car (S101: No), the passenger determination unit 123 determines whether or not the robot 500 is disembarking at the security floor (S103).

[0097] If robot 500 is disembarking at the security floor (S103: Yes), the passenger determination unit 123 turns on the robot boarding flag and proceeds to S106. If robot 500 is not disembarking at the security floor (S103: No), the passenger determination unit 123 clears the robot boarding flag and proceeds to S106.

[0098] If, in S101, robot 500 is in the elevator car 50 (S101: Yes), the passenger determination unit 123 turns on the robot boarding flag, and the process proceeds to S106.

[0099] In S106, the passenger determination unit 123 determines whether the robot boarding flag is on or off (S106). If the robot boarding flag is off (S106: No), the passenger determination unit 123 terminates the passenger mode (S110).

[0100] On the other hand, in S106, if the robot boarding flag is on (S106: Yes), the passenger determination unit 123 determines whether or not a user is currently in the elevator car 50 (S107). If no user is currently in the elevator car 50 (S107: No), the passenger determination unit 123 terminates the passenger mode (S109). If a user is currently in the elevator car 50 (S107: Yes), the passenger determination unit 123 sets the illumination mode to passenger mode (S108).

[0101] Next, the passenger determination unit 123 determines whether the current boarding mode is passenger mode (S112). If it is not passenger mode (S112: No), the process ends and returns to the caller. On the other hand, if it is passenger mode (S112: Yes), the passenger determination unit 123 determines whether the robot 500 is currently disembarking at the security floor (S113).

[0102] If robot 500 is currently disembarking on the security floor (S113: Yes), the suppression processing unit 124 executes the above-described warning activation operation as a suppression process (S114). If robot 500 is not disembarking on the security floor (S113: No), S114 is not executed.

[0103] The passenger determination unit 123 then determines whether the robot 500 has finished disembarking from the elevator car 50 (S115). If disembarking has not yet been completed (S115: No), in S114, the suppression processing unit 124 continues to execute the warning activation operation. On the other hand, if the robot 500 has finished disembarking from the elevator car 50 (S115: Yes), the process ends and returns to the caller.

[0104] In the elevator control system 1 according to this embodiment, the robot 500 sends a request to the server 310 of the robot cloud 300 to move to a security floor where entry for general users is restricted and entry is permitted only to specific persons. The server 310 of the robot cloud 300 receives the request to move to the security floor from the robot 500 and sends the received request to move to the security floor to the server 210 of the elevator cloud 200. The server 210 of the elevator cloud 200 receives the request to move to the security floor and, based on the received request to move to the security floor, generates a destination floor call for the robot to request the elevator car to move to the security floor as the destination floor, and sends the generated destination floor call for the robot to the control panel 100. The control panel 100 can receive destination floor calls and destination floor calls for robots from the server 210 of the elevator cloud 200. The control panel 100 registers the received destination floor call for robots, places the robot 500 into the elevator car 50, moves the elevator car 50 to the security floor, determines whether the robot 500 and a user are riding together in the elevator car 50, and if it determines that they are riding together, sets the boarding mode to the co-boarding mode. If the boarding mode is the co-boarding mode and the elevator car 50 with the robot 500 on board arrives at the security floor, it executes a suppression process to prevent users from disembarking at the security floor.

[0105] Therefore, according to this embodiment, even when a regular user and the robot 500 are riding in the elevator car 50 together, the disembarkation of the regular user is suppressed when the doors open at the security floor, and only the robot 500 is allowed to disembark. Accordingly, according to this embodiment, it is possible to suppress the entry of regular users to the security floor while maintaining the passenger efficiency and operating efficiency of the elevator 2.

[0106] In the elevator control system 1 according to this embodiment, the control panel 100 outputs a warning message inside the elevator car 50 as a suppression process. Therefore, according to this embodiment, by outputting a warning message inside the elevator car 50, it is possible to more reliably suppress general users from entering the security floor.

[0107] In the elevator control system 1 according to this embodiment, the control panel 100 cancels the passenger mode when the robot 500 disembarks from the elevator car 50 at a security floor, or when it determines that all users have disembarked from the elevator car 50 before the elevator car 50 arrives at a security floor. Therefore, according to this embodiment, by canceling the passenger mode when the robot 500 disembarks from the elevator car 50 at a security floor, or when all users have disembarked from the elevator car 50 before the elevator car 50 arrives at a security floor, the passenger efficiency and operating efficiency of the elevator 2 can be ensured.

[0108] In the elevator control system 1 according to this embodiment, when the passenger mode is the passenger mode, the control panel 100 receives a destination floor call from a user that specifies a security floor as the destination floor along with input of a predetermined security release operation, and determines whether the security floor specified in the destination floor call matches the security floor specified in a destination floor call for a robot. If they match, the control panel determines that the user who made the destination floor call is a specific person authorized to enter the security floor and cancels the passenger mode. Therefore, according to this embodiment, the specific person is accurately identified and the passenger mode is canceled, thereby ensuring the passenger efficiency and operating efficiency of the elevator 2.

[0109] Furthermore, in the elevator control system 1 according to this embodiment, when the elevator car 50 carrying the robot 500 arrives at the security floor, or when the elevator car 50 carrying the robot 500 slows down as it approaches the security floor, the control panel 100 performs a suppression process by reducing the illuminance of the lighting device 13 installed at the landing of the security floor. Therefore, according to this embodiment, by reducing the illuminance of the lighting device 13 installed at the landing of the security floor, it is possible to more reliably suppress the entry of general users to the security floor.

[0110] In the elevator control system 1 according to this embodiment, the control panel 100, as a suppression process, sends a request to the security system 161 for authorized personnel to monitor the disembarkation of the robot 500 from the elevator car 50 on the security floor. Upon receiving the request, the security system 161 dispatches authorized personnel to the security floor to monitor the disembarkation of the robot 500 from the elevator car 50. Therefore, according to this embodiment, by dispatching authorized personnel to the security floor to monitor the disembarkation of the robot 500 from the elevator car 50, entry of general users to the security floor can be more reliably suppressed.

[0111] In the elevator control system 1 according to this embodiment, when a destination floor is specified as a security floor in a destination floor call for a robot, the control panel 100 instructs the operation panel 4 inside the elevator car 50 not to display the security floor. If the push button 413 for the security floor is lit up on the operation panel 4 when a destination floor is specified as a robot, there is a possibility that the user will not press the push button 413 to specify the destination floor, making it difficult to accurately determine whether the user has boarded the elevator car 50. In contrast, in this embodiment, even when a security floor is specified as a destination floor in a destination floor call for a robot, the security floor is not lit up or displayed on the operation panel 4, so it is possible to accurately determine whether the user has boarded the elevator car 50, thereby suppressing general users from entering the security floor while maintaining the passenger efficiency and operating efficiency of the elevator 2.

[0112] (modified version) Further possible forms of suppression measures, or in other words, warning activation measures, are as follows: For example, as a suppression process, the suppression processing unit 124 can be configured to send an instruction to the robot 500 via the elevator cloud 200 server 210 and the robot cloud 300 server 310, instructing it to temporarily stop before the landing hold door after disembarking from the elevator car 50, and to resume operation after the elevator car 50 has departed from the security floor.

[0113] In this case, when the robot 500 receives the above instruction, the driving control unit 509 will cause it to disembark from the elevator car 50, then temporarily stop before the hold door 14 at the landing 25, and resume operation after the elevator car 50 has departed from the security floor.

[0114] Figure 10 shows an example of the robot 500 disembarking at the security floor landing 25 in a modified example. Figure 10(a) shows the state in which the robot 500 has started to disembark, and Figure 10(b) shows the state in which the robot 500 has completed disembarking and is temporarily stopped in front of the door 14. By having the robot 500 temporarily stop in front of the door 14 in this way, it is possible to prevent the passenger inside the elevator car 50 from entering the security floor.

[0115] As another example, the robot 500 may use elevator 2 to deliver a package. In this case, in passenger mode, when the elevator car 50 arrives at the security floor, the suppression processing unit 124 can be configured to send a request to the security system 161 in the control room 160 to proceed to the front of the elevator at the security floor landing to hand over the package to the person in charge, and to send an instruction to the robot 500 via the elevator cloud 200 server 210 and the robot cloud 300 server 310 to hand over the package to the person in charge without disembarking from the elevator car 50.

[0116] In this case, when the security system 161 receives the above request, it instructs the relevant person to be dispatched to the elevator 2 at the landing 25 on the security floor for the handover of the package. Also, when the robot T500 receives the above instruction, it performs the action of handing over the package to the relevant person without disembarking from the elevator car 50.

[0117] As another example, if the passenger mode is not the passenger mode, when the elevator car 50 arrives at the security floor, the robot 500 is instructed via the elevator cloud 200 server 210 and the robot cloud 300 server 310 to disembark from the elevator car 50 and hand over the luggage.

[0118] (Second embodiment) In the first embodiment, when the elevator car 50 arrives at the security floor and is in passenger mode, a preventative measure (i.e., a warning activation) is performed to prevent the user from disembarking from the elevator car 50 and entering the security floor. However, there may still be cases where the user disembarks from the elevator car 50. In this third embodiment, a warning is issued if the user disembarks from the elevator car 50 at the security floor.

[0119] The configuration of the elevator control system 1, the server 210 of the elevator cloud 200, the server 310 of the robot cloud 300, and the robot 500 according to this embodiment is the same as in the first embodiment. The control panel 100 according to this embodiment has the same configuration as the first embodiment, but differs from the first embodiment in the following respects.

[0120] In addition to the same functions as in the first embodiment, the passenger determination unit 123 of the control panel 100 according to this embodiment determines whether or not a user has disembarked from the elevator car 50. In addition to the same functions as in the first embodiment, the suppression processing unit 124 of the control panel 100 according to this embodiment also performs a warning process in the passenger mode if, after the elevator car 50 arrives at the security floor and the robot 500 disembarks from the elevator car 50, the passenger determination unit 123 determines that the user has also disembarked from the elevator car 50. Specifically, as a warning process, the suppression processing unit 124 sends an instruction to the robot 500 to output a warning, or sends an instruction to the security system 161 in the control room 160 to output a warning.

[0121] Next, the warning processing by the control panel 100 of the elevator control system 1 of this embodiment, which is configured as described above, will be explained. The overall flow of the elevator control process by the elevator control system 1 of this embodiment is the same as in the first embodiment.

[0122] Figure 11 is a flowchart showing an example of the warning processing procedure according to the second embodiment. Here, before the warning process, the disembarkation suppression process according to the first embodiment is executed in the same manner as S101 to S115 in Figure 8.

[0123] After processing in S115, the passenger determination unit 123 determines whether or not the passenger disembarked at the security floor (S201). If the passenger did not disembark at the security floor (S201: No), processing ends and the system returns to the caller.

[0124] On the other hand, if a user disembarks at the security floor (S201: Yes), the suppression processing unit 124 executes the warning operation process described above (S202). Then, the process ends and returns to the caller.

[0125] In this embodiment of the elevator control system 1, the control panel 100 determines whether or not a user has disembarked from the elevator car. In the passenger mode, if it is determined that a user has also disembarked from the elevator car after the elevator car 50 has arrived at the security floor and the robot 500 has disembarked from the elevator car 50, the control panel 100 executes a warning operation. Therefore, in this embodiment, even if suppression processing such as a warning process is performed, a warning operation is performed for users who have entered the security floor, thereby preventing general users from temporarily entering the security floor while maintaining the passenger efficiency and operating efficiency of the elevator 2.

[0126] Furthermore, in the elevator control system 1 according to this embodiment, the control panel 100 sends an instruction to the robot 500 to output a warning, or sends an instruction to the security system 161 in the control room 160 to output a warning, as part of the warning operation process. Therefore, according to this embodiment, by sending an instruction to the robot 500 to output a warning, or by sending an instruction to the security system 161 in the control room 160 to output a warning, it is possible to more reliably prevent general users from temporarily entering the security floor.

[0127] (modified version) In the above embodiments and modifications, instructions from the control panel 100 to the robot 500, and instructions from the robot 500 to the control panel 100, were given via the server 210 of the elevator cloud 200 and the server 310 of the robot cloud 300, but this is not limited to this. For example, it is possible to configure the system to send instructions directly from the control panel 100 to the robot 500 and from the robot 500 to the control panel 100.

[0128] The control programs executed by the control panel 100, servers 210, 310, and robot 500 according to the above embodiments and modified examples are provided pre-loaded into ROM or the like.

[0129] Each control program executed by the control panel 100, servers 210, 310, and robot 500 according to the above embodiments and modifications may be configured to be provided as a file in an installable or executable format, recorded on a computer-readable recording medium such as a CD-ROM, flexible disk (FD), CD-R, or DVD (Digital Versatile Disk).

[0130] Furthermore, the control programs executed by the control panel 100, servers 210, 310, and robot 500 according to the above embodiments and modifications may be configured to be stored on a computer connected to a network such as the Internet and provided by being downloaded via the network.

[0131] Furthermore, the control programs executed by the control panel 100, servers 210, 310, and robot 500 according to the above embodiments and modified examples may be provided or distributed via a network such as the Internet.

[0132] Each control program executed by the control panel 100, servers 210, 310, and robot 500 according to the above embodiment and modified examples has a modular configuration that includes each of the functional units described above. In actual hardware, the CPU reads the control program from the ROM and executes it, thereby loading each of the functional units into the main memory, and generating each of the functional units in the main memory.

[0133] While several embodiments of the present invention have been described, these embodiments are presented as examples only and are not intended to limit the scope of the invention. These novel embodiments can be carried out in a variety of other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
