Description

[Technical field]

[0001] The present invention relates to an abnormality notification system and a control method for an abnormality notification system. [Background technology]

[0002] In recent years, a technique has become known in which, when an autonomously traveling robot is made to use an elevator, the elevator determines whether an abnormality occurs in the robot.

[0003] Patent document 1 describes an elevator system that determines an abnormality based on abnormality information received from an autonomous moving body that has experienced an abnormality inside the car and is unable to operate, and controls the operation of the elevator to a collection floor where the autonomous moving body is collected. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2021-195257 Summary of the Invention [Problem to be solved by the invention]

[0005] When an abnormality occurs in an autonomous information processing device (robot), it is not always possible for the information processing device to detect the abnormality in its own device and take appropriate action (for example, to report the occurrence of the abnormality and to request assistance). This is because the abnormality in the information processing device may cause the information processing device to lose its function of detecting the abnormality in its own device and its function of reporting the occurrence of the abnormality and to request assistance. In such cases, there is a possibility that it will take a long time to realize that an abnormality has occurred in the information processing device.

[0006] When using an elevator, the information processing device appropriately transmits transmission information such as a door open hold command, a boarding completion signal, and a disembarking completion signal to an elevator control device that controls the operation of the elevator. When the information processing device starts the operation of boarding or disembarking the elevator, the information processing device transmits a door open hold command to the elevator control device. In addition, when the information processing device completes boarding the elevator car or disembarking from the elevator car, the information processing device transmits a boarding completion signal or a disembarking completion signal to the elevator control device.

[0007] For example, if a door-open hold command is not transmitted from an information processing device, there is a possibility that the elevator doors may collide with the information processing device during boarding or alighting. For example, if a boarding completion signal or alighting completion signal is not transmitted from an information processing device, the elevator door open time may be unnecessarily long, and the elevator operation efficiency may decrease. Therefore, it is desirable to notify an administrator, etc., without delay, of information that the information processing device is in a state where it cannot correctly transmit transmission information.

[0008] One aspect of the present invention aims to realize an abnormality notification system that can promptly notify a manager or the like of an abnormality that occurs in an information processing device that uses an elevator. [Means for solving the problem]

[0009] In order to solve the above problems, an abnormality notification system according to one embodiment of the present invention includes a boarding information acquisition unit that acquires boarding information indicating whether or not an autonomously traveling information processing device is in an elevator car, an abnormality determination unit that is configured to receive specific transmission information transmitted by the information processing device and that determines whether or not an abnormality has occurred in the information processing device based on whether or not the transmission information has been received in an elevator control device that controls the operation of the elevator and the boarding information, and an output control unit that causes the elevator control device to output an abnormality occurrence notification if an abnormality has occurred in the information processing device.

[0010] Furthermore, a control method for an abnormality notification system according to one embodiment of the present invention is a control method for an abnormality notification system executed by one or more computers, and includes a boarding information acquisition step of acquiring boarding information indicating whether or not an autonomously traveling information processing device is boarded in an elevator car, an abnormality determination step of determining whether or not an abnormality has occurred in the information processing device based on whether or not the transmission information has been received in an elevator control device that controls the operation of the elevator and is configured to receive specified transmission information transmitted by the information processing device, and the boarding information, and an output control step of causing the elevator control device to output an abnormality occurrence notification if an abnormality has occurred in the information processing device.

[0011] The abnormality notification system according to each aspect of the present invention may be realized by one or more computers. In this case, the control program of the abnormality notification system that realizes the abnormality notification system on a computer by causing the computer to operate as each part (software element) of the abnormality notification system, and the computer-readable recording medium on which it is recorded, also fall within the scope of the present invention. Effect of the Invention

[0012] According to one aspect of the present invention, an abnormality occurring in an information processing device using an elevator can be notified to a manager or the like without delay. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] [Embodiment] Hereinafter, one embodiment of the present invention will be described in detail.

[0015] <Configuration of abnormality notification system 100> First, the configuration of the abnormality notification system 100 will be described with reference to Fig. 1. Fig. 1 is a block diagram showing an example of the configuration of the abnormality notification system 100 according to the first embodiment of the present invention. As shown in Fig. 1, the abnormality notification system 100 includes an elevator 2, an elevator control device 1 that controls the operation of the elevator 2, and an information processing device 3 capable of autonomous travel. The information processing device 3 is also called a robot.

[0016] In the abnormality notification system 100, the information processing device 3 transmits predetermined transmission information to the elevator control device 1. Examples of the predetermined transmission information include a door open hold command, a boarding completion signal, and a disembarking completion signal. The information processing device 3 also transmits a utilization request start and a call registration request to the elevator control device 1. When the elevator control device 1 receives the predetermined transmission information transmitted by the information processing device 3, it may switch the operation mode of the elevator 2 from normal operation to a robot-only operation mode. While the elevator 2 is operating in the robot-only operation mode, the elevator control device 1 does not accept call registration requests from users.

[0017] The elevator control device 1 acquires boarding information indicating whether or not the information processing device 3 is in the elevator car. The elevator control device 1 also judges whether or not the information processing device 3 has an abnormality based on whether or not it has received information transmitted from the information processing device 3 and on the boarding information. If an abnormality has occurred in the information processing device 3, the elevator control device 1 outputs an abnormality occurrence notification indicating that fact. The abnormality occurrence notification is provided to an external device (not shown), such as a computer used by a manager, for example. This allows the manager, etc. to be notified without delay of an abnormality that has occurred in the information processing device 3 that is using the elevator 2.

[0018] Next, the elevator 2, the elevator control device 1, and the information processing device 3 will be described.

[0019] <Elevator 2> 1, the elevator 2 includes a car 21, a door 22, a load sensor 23, and a camera 24. The elevator 2 also includes an operation panel (not shown) at, for example, a landing on each floor, for users to register hall calls. The elevator 2 also includes an operation panel (not shown) in the car 21 for users to register car calls.

[0020] The car 21 operates based on the control of a car control unit 117 of the elevator control device 1, and moves between floors. The door 22 opens and closes according to the control of a door control unit 116 of the elevator control device 1. Note that in conjunction with the opening and closing of the door 22 of the car 21, the door of the landing also opens and closes.

[0021] The load sensor 23 measures the load of the car 21. The measurement data by the load sensor 23 is instantly transmitted to the elevator control device 1. Whether or not the information processing device 3 is in the car 21 can be determined, for example, by whether or not there is a change in the load resulting from the information processing device 3 getting on and off in the measurement data received from the load sensor 23.

[0022] The camera 24 may be a digital camera capable of capturing an image of the inside of the car 21. The car image captured by the camera 24 is instantly transmitted to the elevator control device 1. Whether or not the information processing device 3 is in the car 21 can be determined, for example, by whether or not the information processing device 3 is captured in the car image received from the camera 24. When the camera 24 is a digital video, the car image may be a video captured of the inside of the car 21.

[0023] <Elevator control device 1> The elevator control device 1 receives calls from users and the information processing device 3, and controls the operation of the elevator 2 in response to the received calls. The elevator control device 1 also obtains boarding information indicating whether the information processing device 3 is in the elevator car based on the measurement data obtained from the load sensor 23 and the car image obtained from the camera 24. The elevator control device 1 also receives predetermined transmission information from the information processing device 3.

[0024] The elevator control device 1 judges whether an abnormality has occurred in the information processing device 3 based on whether it has received the boarding information and predetermined transmission information from the information processing device 3. Here, the predetermined transmission information may be any information that the elevator control device 1 is configured to receive from the information processing device 3. For example, the transmission information may be information associated with the opening and closing control of the door 22 of the elevator 2, and may typically be a door open hold command, a boarding completion signal, a disembarking completion signal, or the like.

[0025] 1, the elevator control device 1 includes a control unit 11, a storage unit 12, and an input / output interface 13. The input / output interface 13 is a communication module for communicating between the elevator control device 1 and an information processing device 3, an elevator 2, and an administrator terminal device (not shown).

[0026] [Storage section 12] The storage unit 12 stores various information used by the elevator control device 1. The storage unit 12 stores elevator information 121, call registration information 122, and boarding information 123.

[0027] Fig. 2 is a diagram showing an example of elevator information 121. Elevator information 121 is information relating to the operating state of elevator 2. Elevator information 121 includes information indicating a current floor indicating the current position of car 21, a current moving direction of car 21, and a current operation mode of elevator 2. In the example shown in Fig. 2, an upward arrow "↑" indicates that the moving direction of car 21 is a direction to an upper floor.

[0028] The operation modes of the elevator 2 include a normal operation mode and a robot-only operation mode. The normal operation mode is an operation mode in which the elevator 2 operates in a state in which it is able to accept hall calls and car calls from users, and hall destination floor calls from the information processing device 3. The robot-only operation mode is an operation mode in which a call from the information processing device 3 is registered, and it operates the elevator 2 in a state in which it does not accept hall calls and car calls from users, and only the information processing device 3 can use the elevator 2.

[0029] The call registration information 122 is information related to calls made by users and the information processing device 3. The call registration information 122 includes hall call information 124, car call information 125, and robot call information 126.

[0030] Fig. 3 is a diagram showing an example of the platform call information 124. The platform call information 124 is information related to a platform call made by a user. As shown in Fig. 3, the platform call information 124 includes information indicating the floor where the platform call was made (the platform call floor), i.e., the departure floor of the user, and the travel direction specified by the platform call.

[0031] Fig. 4 is a diagram showing an example of car call information 125. The car call information 125 is information related to car calls made by users. As shown in Fig. 4, the car call information 125 includes information indicating the destination floor (car call floor) of the user.

[0032] Fig. 5 is a diagram showing an example of robot call information 126. Robot call information 126 is information related to a hall / destination floor call by information processing device 3. Robot call information 126 includes information indicating the departure floor and destination floor of information processing device 3. Fig. 5 shows, as an example, robot call information 126 in which a hall / destination floor call from information processing device 3 that boards from the first floor and disembarks on the third floor is registered.

[0033] [Control unit 11] The control unit 11 executes each process performed in the elevator control device 1. As shown in Fig. 1, the control unit 11 includes a boarding information acquisition unit 111, an abnormality determination unit 112, an output control unit 113, a first reception unit 114, a second reception unit 115, a door control unit 116, a car control unit 117, and a switching unit 118.

[0034] (Ride information acquisition unit 111) The boarding information acquisition unit 111 acquires boarding information. Here, the boarding information may be at least one of the following (a) and (b). (a) Information indicating a change in measurement data indicating the total weight of the objects riding in the car 21, measured by the load sensor 23 provided in the car 21. (b) Analysis results of a cage image taken inside cage 21.

[0035] For example, the ride information acquisition unit 111 may be configured to acquire the measurement data itself measured by the load sensor 23 and the car image itself. For example, when the ride information acquisition unit 111 acquires the measurement data from the load sensor 23, the ride information acquisition unit 111 may acquire (extract) the ride information by analyzing a time change in the acquired measurement data. For example, when the ride information acquisition unit 111 acquires a car image from the camera 24, the ride information acquisition unit 111 may acquire (extract) the ride information by analyzing the acquired car image. Alternatively, the ride information acquisition unit 111 may be configured to acquire ride information output from an analysis device (not shown) that acquires and analyzes at least one of the measurement data from the load sensor 23 and the car image from the camera 24.

[0036] (Abnormality determination unit 112) The abnormality determination unit 112 determines whether or not an abnormality has occurred in the information processing device 3 based on whether or not the elevator control device 1 has received predetermined transmission information transmitted by the information processing device 3 and on the boarding information acquired by the boarding information acquisition unit 111. When the transmission information is information associated with the opening / closing control of the door 22 of the elevator 2, the abnormality determination unit 112 may acquire information regarding the presence or absence of reception of a transmission signal from the door control unit 116.

[0037] When the transmission information includes a door open hold command (first door open hold command) and a boarding completion report transmitted from the information processing device 3 when boarding the elevator, the abnormality determination unit 112 may determine whether or not an abnormality has occurred in the information processing device 3 based on the following (i) and (ii) and the boarding information. (i) Whether or not the elevator control device 1 receives transmission information including a first door open hold command within a first predetermined time from the time when a car 21 that the information processing device 3 can board arrives at the departure floor of the information processing device 3. (ii) Whether or not the elevator control device 1 receives transmission information including a boarding completion notification within a second predetermined time period.

[0038] The abnormality determination unit 112 may be capable of determining that, for example, any one of the following first to fourth abnormalities has occurred in the information processing device 3. (First abnormality) The door open hold command is not received, the boarding completion signal is not received, and the boarding information indicates that the passenger is boarding. An abnormality has occurred in the communication system of the information processing device 3. (Second abnormality) The hold door open command is not received, the boarding completion signal is received, and the boarding information indicates that the passenger is boarding. An abnormality has occurred in the function of the information processing device 3 to transmit the hold door open command. (Third Abnormality) A door open hold command has been received, a boarding completion signal has not been received, and the boarding information indicates that the passenger has boarded. An abnormality has occurred in the function of the information processing device 3 to transmit the boarding completion signal. (Fourth abnormality) A door open hold command has been received, a boarding completion signal has not been received, and the boarding information indicates that the passenger is not boarding. An abnormality (including a lack of battery) has occurred in either the operation control unit 312 or the operation unit 32 of the information processing device 3.

[0039] In addition, when the transmission information includes a door open hold command (second door open hold command) and a disembarkation completion report transmitted from the information processing device 3 when the elevator passenger disembarks, the abnormality determination unit 112 may determine whether or not an abnormality has occurred in the information processing device 3 based on the following (iii) and (iv) and the boarding information. (iii) Whether or not the elevator control device 1 receives transmission information including a second door open hold command within a third predetermined time from the time when the car 21 in which the information processing device 3 is riding arrives at the destination floor of the information processing device 3. (iv) Whether or not the elevator control device 1 receives transmission information including a disembarkation completion notification within a fourth predetermined time period.

[0040] The abnormality determination unit 112 may be capable of determining that, for example, any one of the following fifth to eighth abnormalities has occurred in the information processing device 3. (Fifth Abnormality) The door open hold command is not received, the disembarking completion notification is not received, and the boarding information indicates that the passenger has disembarked. An abnormality has occurred in the communication system of the information processing device 3. (Sixth Abnormality) The hold door open command is not received, the disembarking completion notification is received, and the boarding information indicates that the passenger has disembarked. An abnormality has occurred in the function of the information processing device 3 to transmit the hold door open command. (Seventh Abnormality) A door open hold command has been received, a disembarking completion notification has not been received, and the boarding information indicates that the passenger has disembarked. An abnormality has occurred in the function of the information processing device 3 to transmit a disembarking completion signal. (8th abnormality) A door open hold command has been received, a disembarking completion notification has not been received, and the boarding information indicates that the passenger has not disembarked. An abnormality (including a lack of battery) has occurred in either the operation control unit 312 or the operation unit 32 of the information processing device 3.

[0041] The process performed by the abnormality determination unit 112 will be described later with reference to FIGS.

[0042] The abnormality determination unit 112 may be capable of determining that an abnormality different from the first abnormality to the eighth abnormality has occurred in the information processing device 3. For example, the abnormality determination unit 112 may determine that an abnormality has occurred in the information processing device 3 when a door open hold command has been received, a boarding completion signal or a disembarking completion notification has been received, and the boarding information indicates that boarding or disembarking has not occurred. In this case, the information processing device 3 transmits a boarding completion signal or a disembarking completion notification even though boarding into the car 21 or disembarking from the car 21 has not actually been completed. Therefore, in the above-mentioned case, although no abnormality has occurred in the communication system of the information processing device 3, it is considered that an abnormality has occurred in the function for detecting boarding and disembarking, and the information processing device 3 has erroneously recognized that boarding into the car 21 or disembarking from the car 21 has occurred.

[0043] (Output control unit 113) When an abnormality occurs in the information processing device 3, the output control unit 113 outputs an abnormality occurrence notification indicating which of the first to eighth abnormalities has occurred in the information processing device 3, to an external device (e.g., an administrator terminal device) via the input / output interface.

[0044] (First reception unit 114) The first reception unit 114 receives a utilization request from the information processing device 3. The utilization request is generated by the information processing device 3 when it becomes necessary to utilize the elevator 2, and is transmitted to the elevator control device 1.

[0045] (Second reception section 115) The second reception unit 115 receives a call registration request from a user and the information processing device 3. The call registration request from the user may be made using an operation panel (not shown) provided in the hall or car 21 of the elevator 2. When a call registration request from a user is received, the second reception unit 115 stores the departure floor and moving direction of the user, or the destination floor of the user, in the call registration information 122 of the storage unit 12, and registers the hall call or car call of the user. When a call registration request from the information processing device 3 is received, the second reception unit 115 stores the departure floor and destination floor of the information processing device 3 in the robot call information 126 of the storage unit 12, and registers the hall destination floor call of the information processing device 3. When a hall destination floor call of the information processing device 3 is registered, the second reception unit 115 outputs a signal to the switching unit 118 to instruct the start of robot-only operation.

[0046] (Door control unit 116) The door control unit 116 controls the opening and closing of the door 22 of the car 21. When the car 21 arrives at any floor, the door control unit 116 acquires information indicating that the car 21 has stopped from the car control unit 117. Upon acquiring this information, the door control unit 116 transmits a signal to the door 22 of the elevator 2 instructing it to open the door. As a result, the door 22 of the car 21 opens, and the door of the landing also opens in conjunction with the door 22 of the car 21. In addition, the door control unit 116 transmits a signal to the door 22 instructing it to close the door a predetermined time after the door is opened (for example, 20 seconds after the door opening is completed). As a result, the door 22 of the car 21 and the door of the landing close.

[0047] When an open / close button or the like at the landing or in the car 21 is operated while the door 22 is open, the door control unit 116 extends or shortens the door open time according to the operation content.

[0048] The door control unit 116 refers to the elevator information 121 in the storage unit 12, and when the elevator 2 is operating in the robot dedicated operation mode, transmits information indicating the stopping floor of the car 21 and information indicating that the door is open to the information processing device 3. Furthermore, when the elevator 2 is operating in the robot dedicated operation mode, the door control unit 116 maintains the door open state of the door 22 upon receiving a door open hold command from the information processing device 3 while the door 22 is open.

[0049] If the door control unit 116 receives a boarding completion signal from the information processing device 3 within a predetermined time (second predetermined time) after receiving a command to keep the door open from the information processing device 3, the door control unit 116 transmits a signal to close the door to the door 22. If the door control unit 116 receives a boarding completion signal from the information processing device 3 within a predetermined time (second predetermined time) after receiving a command to keep the door open from the information processing device 3, it is considered that the information processing device 3 has normally completed boarding into the car 21. Therefore, by instructing to close the door after receiving the boarding completion signal, the door control unit 116 can close the door 22 promptly after the information processing device 3 has completed boarding into the car 21.

[0050] If the door control unit 116 receives a disembarking completion signal from the information processing device 3 within a predetermined time (fourth predetermined time) after receiving a hold-door-open command from the information processing device 3, the door control unit 116 transmits a signal to close the door to the door 22. If the door control unit 116 receives a disembarking completion signal from the information processing device 3 within a predetermined time (fourth predetermined time) after receiving a hold-door-open command from the information processing device 3, it is considered that the information processing device 3 has normally completed disembarking from the car 21. Therefore, by instructing to close the door after receiving the disembarking completion signal, the door control unit 116 can close the door 22 promptly after the information processing device 3 has completed disembarking from the car 21.

[0051] Furthermore, when the information processing device 3 is in the car 21, the door control unit 116 may instruct the door to close while the robot-only operation mode of the elevator 2 is still in operation. Specifically, when the information processing device 3 is in the car 21, the door control unit 116 instructs the door 22 to close without outputting a signal to the switching unit 118 to instruct the end of the robot-only operation.

[0052] Furthermore, the door control unit 116 ends the robot-only operation when the information processing device 3 is not in the car 21. Specifically, the door control unit 116 outputs a signal to the switching unit 118 to instruct the end of the robot-only operation, and transmits a signal to the door 22 to instruct the door to close.

[0053] For example, when the information processing device 3 does not get on the car 21 at the departure floor of the information processing device 3, the door control unit 116 outputs a signal to the switching unit 118 to instruct the end of robot-only operation. Also, when the information processing device 3 gets off the car 21 after the door opens at the destination floor of the information processing device 3, the door control unit 116 outputs a signal to the switching unit 118 to instruct the end of robot-only operation.

[0054] (Cage control unit 117) The car control unit 117 moves the car 21 based on the registered hall call, car call, and hall destination floor call by the information processing device 3. When the car 21 arrives at the departure floor of the information processing device 3, the car control unit 117 outputs information indicating the stop floor of the car 21 to the door control unit 116.

[0055] The car control unit 117 determines the destination floor of the car 21 based on the departure floor and destination floor of the user and the information processing device 3 recorded in the call registration information 122 and the operation mode of the elevator 2 .

[0056] For example, when the operation mode of the elevator 2 is the normal operation mode, the car control unit 117 determines the destination floor of the car 21 by referring to the hall call information 124 and the car call information 125, and transmits a signal to the car 21 to instruct it to move to the determined floor. As a result, the car 21 of the elevator 2 moves to the destination floor based on the hall call and car call of the user.

[0057] Furthermore, when the operation mode of the elevator 2 is the robot-only operation mode, the car control unit 117 refers to the robot call information 126 to determine the destination floor of the car 21, and transmits a signal to the car 21 to instruct it to move to the determined floor. As a result, the car 21 of the elevator 2 moves to the departure floor and destination floor based on the hall destination floor call of the information processing device 3.

[0058] When the robot-only operation is started, the car control unit 117 may instruct the elevator 2 to respond to a registered car call and then to move to the departure floor of the information processing device 3. This allows a user who was in the car 21 when the robot-only operation was started to disembark before the information processing device 3 is allowed to board. When the robot-only operation is started, the car control unit 117 may delete a registered hall call, or may cause the elevator 2 to respond to a registered hall call after the robot-only operation is ended.

[0059] (Switching unit 118) The switching unit 118 switches the operation mode of the elevator 2. For example, when a call from the information processing device 3 is registered in the robot call information 126, the second reception unit 115 outputs a signal instructing the start of robot-only operation to the switching unit 118. Upon receiving the signal, the switching unit 118 switches the operation mode of the elevator 2 stored in the elevator information 121 from the normal operation mode to the robot-only operation mode. This starts the robot-only operation of the elevator 2.

[0060] Furthermore, when the switching unit 118 receives a signal instructing the start or end of robot-only operation from the door control unit 116, it switches the operation mode of the elevator 2 stored in the memory unit 12 from the robot-only operation mode to the normal operation mode. This switches the operation mode of the elevator 2.

[0061] <Information processing device 3> The information processing device 3 is an autonomously movable device, and can move between floors using the elevator 2. Although only one information processing device 3 is illustrated in Fig. 1, the abnormality notification system 100 may include multiple information processing devices 3.

[0062] 1, the information processing device 3 includes a control unit 31 and an operation unit 32. The control unit 31 executes the processes performed in the information processing device 3. The control unit 31 includes a usage request transmission unit 311, an operation control unit 312, a door open hold command transmission unit 313, a boarding completion report transmission unit 314, and a disembarking completion report transmission unit 315. The operation unit 32 operates under the control of the operation control unit 312, and moves the information processing device 3 to a desired location.

[0063] (Usage request sending unit 311) When the information processing device 3 needs to use the elevator 2, the use request sending unit 311 sends a use request to the elevator control device 1. In addition, the use request sending unit 311 outputs a call registration request to the elevator control device 1. The call registration request includes information indicating the departure floor and destination floor of the information processing device 3.

[0064] (Operation control unit 312) The operation control unit 312 operates the operation unit 32 to move the information processing device 3 to a desired position. For example, the operation control unit 312 operates the operation unit 32 according to the operation state of the elevator 2 that has made the call registration request. When the operation control unit 312 receives information from the elevator control device 1 indicating that the registration of the hall destination floor call has been completed, it operates the operation unit 32. As a result, the information processing device 3 moves to the hall and waits for the elevator 2.

[0065] Furthermore, when the elevator 2 is in a standby state and information indicating that the door has opened is received from the elevator control device 1, the operation control unit 312 determines whether or not the floor on which the information processing device 3 is currently located coincides with the floor on which the car 21 is stopped. After that, the operation control unit 312 operates the operation unit 32, so that the information processing device 3 gets into the car 21.

[0066] Furthermore, when the information processing device 3 is in the car 21 and receives information from the elevator control device 1 indicating that the door has opened, the operation control unit 312 determines whether or not the destination floor of the information processing device 3 matches the floor on which the car 21 is stopped. After that, the operation control unit 312 operates the operation unit 32, causing the information processing device 3 to disembark from the car 21. (Door open hold command transmission unit 313) When the floor where the information processing device 3 is currently located matches the floor where the car 21 is stopped, the hold door open command transmission unit 313 transmits a hold door open command (first hold door open command) to the elevator control device 1. When the destination floor of the information processing device 3 matches the floor where the car 21 is stopped, the operation control unit 312 transmits a hold door open command (second hold door open command) to the elevator control device 1. (Ride completion report sending unit 314) The boarding completion report transmitting unit 314 transmits a boarding completion signal to the elevator control device 1 after the boarding operation of the information processing device 3 into the car 21 is completed. (Disembarkation completion report transmission unit 315) The alighting completion report transmitting unit 315 transmits an alighting completion signal to the elevator control device 1 after the alighting operation from the car 21 of the information processing device 3 is completed.

[0067] <Processing upon boarding> FIG. 6 is a sequence diagram showing an example of the flow of processing performed by an information processing device in the car 21 of the elevator 2 and an elevator control device.

[0068] When the information processing device 3 needs to use the elevator 2, the use request sending unit 311 generates a use request (S11) and sends it to the elevator control device 1. When the first receiving unit 114 of the elevator control device 1 receives the use request (S21), it sends a use request reception completion notification to the information processing device 3.

[0069] When the utilization request transmission unit 311 receives the acceptance completion notification from the elevator control device 1, it generates a call registration request (S12) and outputs it to the elevator control device 1 (S13). The call registration request includes information indicating the departure floor and destination floor of the information processing device 3.

[0070] When the second reception unit 115 receives a call registration request from the information processing device 3, it accepts the call registration of the information processing device 3 (S22) and stores information indicating the departure floor and destination floor of the information processing device 3 in the robot call information 126. When the call registration by the information processing device 3 is completed, the second reception unit 115 outputs a signal to the switching unit 118 to instruct the start of robot-only operation. When the switching unit 118 acquires the signal, it switches the operation mode of the elevator 2 stored in the elevator information 121 to the robot-only operation mode. This starts the robot-only operation (S23). Here, the second reception unit 115 may transmit information indicating that the call registration has been completed to the information processing device 3. When the operation control unit 312 of the information processing device 3, whose call registration request has been accepted by the elevator control device 1, receives the information, it operates the operation unit 32 and moves the information processing device 3 to the landing of the departure floor.

[0071] When the robot-only operation is started, the car control unit 117 refers to the robot call information 126 and moves the car 21 to the departure floor of the information processing device 3. Before moving the car 21 to the departure floor of the information processing device 3, the car control unit 117 may refer to the car call information 125 and move the car 21 to a floor designated by the car call of the user. When the car 21 arrives at the departure floor of the information processing device 3, the car control unit 117 outputs information indicating the stop floor of the car 21 to the door control unit 116, and based on the information, the door control unit 116 instructs the door 22 to open the door (S24). Then, the car control unit 117 transmits information indicating that the car 21 has stopped and information indicating the floor at which the car 21 has stopped to the information processing device 3. Meanwhile, the door control unit 116 starts measuring the elapsed time after the door is opened (S25).

[0072] When the operation control unit 312 of the information processing device 3 receives the information indicating that the car 21 has stopped and the information indicating the floor at which the car 21 has stopped, it determines whether or not the current floor of the information processing device 3 is the same as the car stop floor (S14). If the current floor of the information processing device 3 is not the same as the car stop floor (NO in S16), the operation control unit 312 repeats the same process until YES is obtained in step S16.

[0073] If the current floor of the information processing device 3 is the same as the car stop floor (YES in S14), that is, if the car 21 stops at the departure floor of the information processing device 3 and the door opens, the operation control unit 312 operates the operation unit 32. This causes the information processing device 3 to start the boarding operation into the car 21 (S15). When the information processing device 3 starts the boarding operation into the car 21, the door open hold command transmission unit 313 transmits a door open hold command to the elevator control device 1.

[0074] After step S25, the door control unit 116 determines whether or not a predetermined time has elapsed since the door was opened (S26).

[0075] When a predetermined time (first predetermined time) has elapsed since the door was opened (YES in S26), the elevator control device 1 performs process A shown in Fig. 7. Process A will be described later.

[0076] On the other hand, if the predetermined time has not passed since the door was opened (NO in S26), the door control unit 116 judges whether or not a door open hold command has been received (S27). If a door open hold command has been received (YES in S27), the door control unit 116 keeps the door 22 open. In addition, the door control unit 116 judges whether or not a boarding completion signal has been received (S28). If a boarding completion signal has not been received (NO in S28), the door control unit 116 repeats the process of step S28 until a predetermined time (second predetermined time) has passed since the door was opened (until YES in S29).

[0077] When the boarding operation of the information processing device 3 into the car 21 is completed (S16), the boarding completion report transmitting unit 314 transmits a boarding completion signal to the elevator control device 1.

[0078] When the door control unit 116 receives the boarding completion signal (YES in S28), the elevator control device 1 performs process B shown in Fig. 8. On the other hand, when the door control unit 116 does not receive the boarding completion signal (NO in S28) and a predetermined time has passed since the door was opened (YES in S29), the elevator control device 1 performs process C shown in Fig. 9.

[0079] In a state where the door control unit 116 has not received a door open hold command (NO in S27), if the boarding completion signal is received (YES in S30) and if boarding of the information processing device 3 is confirmed based on the boarding information, the abnormality determination unit 112 determines that the abnormality that occurred in the information processing device 3 is a second abnormality (S31: boarding information acquisition step, abnormality determination step). The second abnormality is intended to be an abnormality that occurred in the function of the information processing device 3 to transmit the door open hold command. Then, the output control unit 113 transmits an abnormality occurrence notification to an external device such as an administrator terminal device (S32: output control step). After that, the door control unit 116 instructs the door 22 to close the door (S33). After the door is closed, the car control unit 117 moves the car 21.

[0080] If the door control unit 116 does not receive the door open hold command and the boarding completion signal (NO in S27 and S30), the elevator control device 1 performs the process of step S26 again.

[0081] (Process A) FIG. 7 is a sequence diagram showing an example of the flow of the process A shown in FIG.

[0082] When a predetermined time (first predetermined time) has passed since the door was opened (YES in S26 of FIG. 6) and boarding of the information processing device 3 is confirmed based on the boarding information (YES in S34: boarding information acquisition step), the abnormality determination unit 112 determines that the abnormality that occurred in the information processing device 3 is a first abnormality (S35: abnormality determination step). The first abnormality is intended to be an abnormality that occurred in the communication system of the information processing device 3. Then, the output control unit 113 transmits an abnormality occurrence notification to an external device such as an administrator terminal device (S36: output control step). Thereafter, the door control unit 116 instructs the door 22 to close the door (S33). After the door is closed, the car control unit 117 moves the car 21.

[0083] On the other hand, if a predetermined time (first predetermined time) has passed since the door was opened (YES in S26 in FIG. 6) and boarding of the information processing device 3 has not been confirmed based on the boarding information (NO in S34: boarding information acquisition step), the door control unit 116 outputs a signal to the switching unit 118 to instruct the end of the robot-only operation. When the switching unit 118 receives the signal, it ends the robot-only operation (S37). After the robot-only operation ends, the door control unit 116 instructs the door 22 to close the door (S33).

[0084] (Process B) FIG. 8 is a sequence diagram showing an example of the flow of the process B shown in FIG.

[0085] When the door control unit 116 receives a door open hold command and a boarding completion signal (YES in S28 in FIG. 6) and boarding of the information processing device 3 is confirmed based on the boarding information (YES in S38: boarding information acquisition step), the door control unit 116 instructs the door 22 to close the door (S33). A YES result in step S38 means that no abnormality has occurred in the information processing device 3 and the information processing device 3 has normally boarded inside the car 21. After the door is closed, the car control unit 117 moves the car 21.

[0086] On the other hand, when the door control unit 116 receives the door open hold command and the boarding completion signal (YES in S28 of FIG. 6), but the boarding of the information processing device 3 is not confirmed based on the boarding information (NO in S38: boarding information acquisition step), the door control unit 116 outputs a signal to the switching unit 118 to instruct the end of the robot-only operation. When the switching unit 118 acquires the signal, it ends the robot-only operation (S39). After the robot-only operation ends, the door control unit 116 instructs the door 22 to close the door (S33). When NO in step S38, for example, it is considered that the information processing device 3 erroneously recognizes that it is in the car 21, even though it is not actually in the car 21. In this case, the abnormality determination unit 112 may determine that an abnormality has occurred in the function of detecting the boarding state of the information processing device 3. In addition, the output control unit 113 may transmit an abnormality occurrence notification to an external device such as an administrator terminal device.

[0087] (Process C) FIG. 9 is a sequence diagram showing an example of the flow of the process C shown in FIG.

[0088] If the door control unit 116 does not receive a boarding completion signal (NO in S28), and a predetermined time (second predetermined time) has passed since the door was opened (YES in S29), and boarding of the information processing device 3 is confirmed based on the boarding information (YES in S40: boarding information acquisition step), the abnormality determination unit 112 determines that the abnormality occurring in the information processing device 3 is a third abnormality (S41: abnormality determination step). The third abnormality refers to an abnormality occurring in the function of the information processing device 3 to transmit a boarding completion signal. Then, the output control unit 113 transmits an abnormality occurrence notification to an external device such as an administrator terminal device (S42: output control step). After that, the door control unit 116 instructs the door 22 to close the door (S33). After the door is closed, the car control unit 117 moves the car 21.

[0089] On the other hand, if the door control unit 116 does not receive a boarding completion signal (NO in S28), and a predetermined time (second predetermined time) has passed since the door was opened (YES in S29), and boarding of the information processing device 3 has not been confirmed based on the boarding information (NO in S40: boarding information acquisition step), the abnormality determination unit 112 determines that the abnormality that occurred in the information processing device 3 is a fourth abnormality (S43: abnormality determination step). The fourth abnormality refers to an abnormality that occurred in either the operation control unit 312 or the operation unit 32 of the information processing device 3. Then, the output control unit 113 transmits an abnormality occurrence notification to an external device such as an administrator terminal device (S44: output control step). After that, the door control unit 116 instructs the door 22 to close the door (S33). After the door is closed, the car control unit 117 moves the car 21.

[0090] In this way, the abnormality notification system 100 can determine an abnormality occurring in the information processing device riding in the cage 21 of the elevator 2. The abnormality notification system 100 can also determine whether the elevator control device 1 has received the transmission information from the information processing device 3 riding in the cage 21 of the elevator 2, and can specify which of the first to fourth abnormalities the abnormality occurring in the information processing device 3 is based on the riding information. If an abnormality occurs in the information processing device 3, the abnormality notification system 100 outputs an abnormality occurrence notification that notifies the information processing device 3 from the elevator 2 that an abnormality has occurred. In this way, the abnormality notification system 100 can determine what kind of abnormality has occurred in the information processing device 3 using the elevator 2, and then notify the administrator or the like without delay that an abnormality has occurred in the information processing device 3. Even if the information processing device 3 is no longer able to detect an abnormality in its own device or issue a rescue request, the abnormality notification system 100 can detect the occurrence of an abnormality in the information processing device 3 using the elevator 2 and output an abnormality occurrence notification.

[0091] <Disembarking Procedure 1> Even if any of the first to third abnormalities occurs in the information processing device 3 when boarding, the information processing device 3 can board and move in the car 21. Fig. 10 is a sequence diagram showing an example of the flow of processing performed by the information processing device 3 and the elevator control device 1 when a passenger gets off the car 21 of the elevator 2.

[0092] When the car 21 stops at any floor, the door control unit 116 instructs the door 22 to open the door (S61), and transmits information indicating that the door has been opened and information indicating the stopping floor of the car 21 to the information processing device 3. In addition, the door control unit 116 starts measuring the elapsed time since the door was opened (S62).

[0093] When the operation control unit 312 of the information processing device 3 receives information indicating that the door has opened and information indicating the stopping floor of the car 21 while the passenger is in the car 21, it determines whether or not the destination floor of the information processing device 3 is the same as the stopping floor of the car 21 (S51). If the destination floor of the information processing device 3 is not the same as the stopping floor of the car 21 (NO in S51), the same process is repeated until YES is obtained in step S51.

[0094] If the destination floor of the information processing device 3 is the same as the stop floor of the car 21 (YES in S51), the operation control unit 312 controls the operation unit 32 to start the disembarking operation (S52). In addition, the door open hold command transmission unit 313 transmits a door open hold command to the elevator control device 1.

[0095] After step S62, the door control unit 116 determines whether or not a predetermined time has elapsed since the door was opened (S63).

[0096] When a predetermined time (third predetermined time) has elapsed since the door was opened (YES in S63), the elevator control device 1 performs process D shown in Fig. 11. Process D will be described later.

[0097] On the other hand, if the predetermined time (third predetermined time) has not elapsed since the door was opened (NO in S63), the door control unit 116 judges whether or not a door-open hold command has been received (S64). If a door-open hold command has been received (YES in S64), the door control unit 116 keeps the door 22 open. In addition, the door control unit 116 judges whether or not a disembarking completion signal has been received (S65). If a disembarking completion signal has not been received (NO in S65), the door control unit 116 repeats the process of step S65 until the predetermined time (fourth predetermined time) has elapsed since the door was opened (until YES in S66).

[0098] When the door control unit 116 receives the alighting completion signal (YES in S65), the elevator control device 1 performs process E shown in Fig. 12. On the other hand, when the door control unit 116 does not receive the alighting completion signal (NO in S65) and a predetermined time (fourth predetermined time) has elapsed since the door was opened (YES in S66), the elevator control device 1 performs process F shown in Fig. 13.

[0099] In a state where the door control unit 116 has not received a door open hold command (NO in S64), if the door control unit 116 receives a disembarking completion signal (YES in S67) and if disembarking of the information processing device 3 is confirmed based on the boarding information, the abnormality determination unit 112 determines that the abnormality that occurred in the information processing device 3 is the sixth abnormality (S68: boarding information acquisition step, abnormality determination step). The sixth abnormality is intended to be an abnormality that occurred in the function of the information processing device 3 to transmit the door open hold command. Note that, when the information processing device 3 boards the car 21, it may have already been determined that the abnormality that occurred in the information processing device 3 is the second abnormality. If the second abnormality did not occur in the information processing device 3 when boarding the car 21, it means that the sixth abnormality has newly occurred after boarding the car 21. Then, the output control unit 113 transmits an abnormality occurrence notification to an external device such as an administrator terminal device (S69: output control step). After that, the door control unit 116 instructs the door 22 to close the door (S71). After the door is closed, the car control unit 117 moves the car 21.

[0100] If the door control unit 116 does not receive the hold-open door command and the disembarkation completion signal (NO in S64 and S67), the elevator control device 1 performs the process of step S63 again.

[0101] (Process D) FIG. 11 is a sequence diagram showing an example of the flow of the process D shown in FIG.

[0102] When a predetermined time (third predetermined time) has elapsed since the door was opened (YES in S63 in FIG. 10) and the disembarking of the information processing device 3 is confirmed based on the boarding information (YES in S72: boarding information acquisition step), the abnormality determination unit 112 determines that the abnormality that occurred in the information processing device 3 is the fifth abnormality (S73: abnormality determination step). The fifth abnormality is intended to be an abnormality that occurred in the communication system of the information processing device 3. Note that the abnormality that occurred in the information processing device 3 may have already been determined to be the first abnormality when the information processing device 3 boards the car 21. If the first abnormality did not occur in the information processing device 3 when boarding the car 21, this means that the fifth abnormality has newly occurred after boarding the car 21. Then, the output control unit 113 transmits an abnormality occurrence notification to an external device such as an administrator terminal device (S74: output control step). After that, the door control unit 116 outputs a signal to the switching unit 118 to instruct the end of the robot-only operation. When the switching unit 118 receives the signal, it ends the robot-only operation (S70). After the robot-only operation ends, the door control unit 116 instructs the door 22 to close (S71).

[0103] On the other hand, if a predetermined time (third predetermined time) has passed since the door was opened (YES in S63 in FIG. 10) and the disembarking of the information processing device 3 has not been confirmed based on the boarding information (NO in S72: boarding information acquisition step), the abnormality determination unit 112 determines that the abnormality that occurred in the information processing device 3 is the eighth abnormality (S75: abnormality determination step). The eighth abnormality refers to an abnormality that occurred in either the operation control unit 312 or the operation unit 32 of the information processing device 3. Since the information processing device 3 is able to board the car 21, this eighth abnormality is an abnormality that occurred after boarding the car 21. Then, the output control unit 113 transmits an abnormality occurrence notification to an external device such as an administrator terminal device (S76: output control step). After that, the door control unit 116 instructs the door 22 to close the door (S71). After the door is closed, the car control unit 117 moves the car 21.

[0104] (Process E) FIG. 12 is a sequence diagram showing an example of the flow of the process E shown in FIG.

[0105] When the door control unit 116 receives a door open hold command and a disembarking completion signal (YES in S65 of FIG. 10) and disembarking of the information processing device 3 is confirmed based on the boarding information (YES in S77: boarding information acquisition step), the door control unit 116 outputs a signal to the switching unit 118 to instruct the end of robot-only operation. When the switching unit 118 acquires the signal, it ends the robot-only operation (S70). After the robot-only operation ends, the door control unit 116 instructs the door 22 to close the door (S71). A case of YES in step S77 means that no abnormality has occurred in the information processing device 3 and the information processing device 3 has normally disembarked from inside the car 21.

[0106] On the other hand, when the door control unit 116 receives the door open hold command and the disembarking completion signal (YES in S65 of FIG. 10) and disembarking of the information processing device 3 is not confirmed based on the boarding information (NO in S77: boarding information acquisition step), the abnormality determination unit 112 determines that an abnormality has occurred in the information processing device 3 (S80: abnormality determination step). Then, the output control unit 113 transmits an abnormality occurrence notification to an external device such as an administrator terminal device (S81: output control step). After that, the door control unit 116 instructs the door 22 to close the door (S71). After the door is closed, the car control unit 117 moves the car 21. When NO in step S77, for example, it is considered that the information processing device 3 erroneously recognizes that the passenger has disembarked from the car 21 when in fact the passenger has not disembarked from the car 21. In this case, the abnormality determination unit 112 may determine that an abnormality has occurred in the function of detecting the boarding state of the information processing device 3.

[0107] (Process F) FIG. 13 is a sequence diagram showing an example of the flow of the process F shown in FIG.

[0108] If the door control unit 116 does not receive the disembarking completion signal (NO in S65), and a predetermined time (fourth predetermined time) has elapsed since the door was opened (YES in S66), and disembarking of the information processing device 3 is confirmed based on the boarding information (YES in S82: boarding information acquisition step), the abnormality determination unit 112 determines that the abnormality occurring in the information processing device 3 is the seventh abnormality (S83: abnormality determination step). The seventh abnormality refers to an abnormality occurring in the function of the information processing device 3 to transmit the disembarking completion signal. Then, the output control unit 113 transmits an abnormality occurrence notification to an external device such as an administrator terminal device (S84: output control step). After that, the door control unit 116 outputs a signal to the switching unit 118 to instruct the end of the robot-only operation. When the switching unit 118 receives the signal, it ends the robot-only operation (S70). After the robot-only operation ends, the door control unit 116 instructs the door 22 to close the door (S71).

[0109] On the other hand, if the door control unit 116 does not receive a disembarking completion signal (NO in S65), and a predetermined time (fourth predetermined time) has passed since the door was opened (YES in S66), and disembarking of the information processing device 3 has not been confirmed based on the boarding information (NO in S82: boarding information acquisition step), the abnormality determination unit 112 determines that the abnormality that occurred in the information processing device 3 is the eighth abnormality (S85: abnormality determination step). This eighth abnormality is an abnormality that occurred after the information processing device 3 boarded the car 21, since the information processing device 3 was able to board the car 21. Then, the output control unit 113 transmits an abnormality occurrence notification to an external device such as an administrator terminal device (S86: output control step). After that, the door control unit 116 instructs the door 22 to close the door (S71). After the door is closed, the car control unit 117 moves the car 21.

[0110] In this way, the abnormality notification system 100 can also determine an abnormality occurring in an information processing device that is getting off the elevator 2. The abnormality notification system 100 can also determine whether the elevator control device 1 has received information transmitted from the information processing device 3 that is getting off the elevator 2, and can also specify which of the fifth to eighth abnormalities the abnormality occurring in the information processing device 3 is, based on the boarding information. If an abnormality occurs in the information processing device 3, the abnormality notification system 100 outputs an abnormality occurrence notification from the elevator 2 to notify the information processing device 3 that an abnormality has occurred.

[0111] As a result, the abnormality notification system 100 can determine what type of abnormality has occurred in the information processing device 3 that uses the elevator 2, and can promptly notify a manager or the like of the occurrence of an abnormality in the information processing device 3. Even if the information processing device 3 is no longer able to detect its own abnormality or issue a rescue request, the abnormality notification system 100 can detect the occurrence of an abnormality in the information processing device 3 that uses the elevator 2, and output an abnormality occurrence notification.

[0112] <Disembarking Procedure 2> When the information processing device 3 is in the car 21, the fourth abnormality does not occur in the information processing device 3. However, after getting into the car 21, it is possible that the battery of the information processing device 3 may become insufficient, causing the eighth abnormality. Therefore, when the information processing device 3 gets off the car 21, it is preferable not to omit the transmission of the abnormality occurrence notification indicating that the eighth abnormality has occurred.

[0113] On the other hand, if the first or second abnormality occurs in the information processing device 3, an abnormality occurrence notification to that effect has already been transmitted when the information processing device 3 gets on to the car 21. Therefore, when the information processing device 3 gets off from the car 21, the transmission of an abnormality occurrence notification to the effect that the fifth or sixth abnormality has occurred can be omitted.

[0114] In this way, a part of the process for determining an abnormality occurring in the information processing device 3 when disembarking, shown in Fig. 10 to Fig. 13, may be omitted. Such a process when disembarking will be described with reference to Fig. 14 and Fig. 15. For ease of explanation, the same reference numerals are given to members having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0115] FIG. 14 is a sequence diagram showing another example of the flow of processing performed by the information processing device 3 and the elevator control device 1 when a passenger gets off the car 21 of the elevator 2.

[0116] When the car 21 stops at any floor, the door control unit 116 instructs the door 22 to open the door (S61), and transmits information indicating that the door has been opened and information indicating the stopping floor of the car 21 to the information processing device 3. In addition, the door control unit 116 starts measuring the elapsed time since the door was opened (S62).

[0117] After step S62, the door control unit 116 judges whether or not the alighting completion signal has been received (S65). If the alighting completion signal has not been received (NO in S65), the door control unit 116 repeats the process of step S65 until a predetermined time (fourth predetermined time) has elapsed since the door was opened (until YES is determined in S66).

[0118] When the door control unit 116 receives the alighting completion signal (YES in S65), the elevator control device 1 performs process E shown in Fig. 12. On the other hand, when the door control unit 116 does not receive the alighting completion signal (NO in S65) and a predetermined time (fourth predetermined time) has elapsed since the door was opened (YES in S66), the elevator control device 1 performs process F shown in Fig. 13.

[0119] This makes it possible to efficiently determine an abnormality occurring in the information processing device 3 that is able to board the car 21.

[0120] <Disembarking Procedure 3> FIG. 15 is a sequence diagram showing another example of the flow of processing performed by the information processing device 3 and the elevator control device 1 when a passenger gets off the car 21 of the elevator 2.

[0121] If the third abnormality occurs in the information processing device 3, an abnormality occurrence notification to that effect has already been transmitted when the information processing device 3 gets into the car 21. Furthermore, if the third abnormality occurs in the information processing device 3, it is highly likely that the seventh abnormality has also occurred. Therefore, when the information processing device 3 gets off the car 21, it is possible to omit the transmission of an abnormality occurrence notification to the effect that the seventh abnormality has occurred. Therefore, in the sequence diagram shown in FIG. 15, the process of determining that the seventh abnormality has occurred and the process of transmitting an abnormality occurrence notification are omitted.

[0122] When it is confirmed that the information processing device 3 has disembarked based on the boarding information (YES in S82), the door control unit 116 outputs a signal to the switching unit 118 to instruct the robot-only operation to end. When the switching unit 118 receives the signal, it ends the robot-only operation (S70). After the robot-only operation ends, the door control unit 116 instructs the door 22 to close (S71).

[0123] On the other hand, if disembarking of the information processing device 3 is not confirmed based on the boarding information (NO in S82), the abnormality determination unit 112 determines that the abnormality that occurred in the information processing device 3 is the eighth abnormality (S85). Then, the output control unit 113 transmits an abnormality occurrence notification to an external device such as an administrator terminal device (S86). After that, the door control unit 116 instructs the door 22 to close the door (S71). After the door is closed, the car control unit 117 moves the car 21.

[0124] This makes it possible to more efficiently determine an abnormality occurring in the information processing device 3 that is able to board the car 21.
