Description

[Technical Field]

[0001] An embodiment of the present invention relates to a moving body, a maintenance management method for a passenger conveyor, and a maintenance management system for a passenger conveyor. [Background technology]

[0002] During regular inspections of escalators, a type of passenger conveyor, workers stand on the escalator steps and check various items. However, traveling to the escalator in question each time an inspection is required places a heavy burden on the workers. For this reason, technology has been developed to enable autonomous mobile devices, such as robots, to inspect escalators in place of workers. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2023-167662 Summary of the Invention [Problem to be solved by the invention]

[0004] When a moving body inspects an escalator, it steps onto a step and uses a built-in camera device to take pictures of the components that make up the escalator and the surrounding environment, and then analyzes the captured images to check for any abnormalities.

[0005] If an earthquake occurs while a moving object is on an escalator step, the moving object may fall off the step or tip over on the step, potentially damaging the moving object or the escalator. Therefore, if an earthquake occurs while a moving object is inspecting an escalator, a maintenance worker will visit the site and check to see if there are any problems with the moving object or escalator due to the moving object tipping over, etc. If a problem is found, the maintenance worker will take action to restore operation.

[0006] However, even if an earthquake occurs during inspection work using a mobile unit, depending on the situation, there may be no malfunction in either the mobile unit or the escalator, and the inspection work can continue. Therefore, if an inspection work is interrupted and a maintenance worker goes to the site to check every time an earthquake occurs during inspection work using a mobile unit, there is a problem that the labor of the maintenance worker may be wasted.

[0007] The present invention has been made in consideration of the above circumstances, and aims to provide a moving body, a passenger conveyor maintenance management method, and a passenger conveyor maintenance management system that automatically and safely resume maintenance and inspection processing when an earthquake occurs during maintenance and inspection processing of a passenger conveyor and the maintenance and inspection processing is interrupted. [Means for solving the problem]

[0008] According to an embodiment for achieving the above object, a mobile body includes a conveyor information acquisition unit and a maintenance and inspection processing unit. The conveyor information acquisition unit acquires status information of a passenger conveyor that is the target of maintenance and inspection. If a disaster occurs while the conveyor information acquisition unit is acquiring status information of the passenger conveyor for maintenance and inspection processing, the maintenance and inspection processing unit stops the process of acquiring the status information of the passenger conveyor, and thereafter, upon recognizing that no abnormalities have been detected in the mobile body or the passenger conveyor, causes the conveyor information acquisition unit to resume the process of acquiring the status information of the passenger conveyor.

DETAILED DESCRIPTION OF THE INVENTION

[0010] Below, we will explain a maintenance management system in which an elevator cloud that functions as a maintenance management device according to one embodiment of the present invention maintains and manages an escalator, which is a passenger conveyor, using a robot device as an autonomously movable body.

[0011] <Configuration of a maintenance management system according to one embodiment> 1 is an overall diagram showing the configuration of a maintenance management system 1 according to one embodiment. The maintenance management system 1 is configured by connecting an escalator 10 to be maintained and inspected, a robot device 20, an elevator cloud 30, and a robot cloud 40 via a wide area communication network NW.

[0012] The maintenance management system 1 is communicatively connected to a manufacturer maintenance center device C1 installed in a manufacturer maintenance center within the manufacturer of the escalator 10, a building disaster prevention center device C2 installed in a building disaster prevention center within the building in which the escalator 10 is installed, and an earthquake information management device C3 that transmits earthquake occurrence information, which is one type of disaster occurrence information.

[0013] Specifically, the manufacturer maintenance center device C1 is communicatively connected to the elevator cloud 30 and the robot cloud 40 via the wide area communication network NW, the building disaster prevention center device C2 is communicatively connected to the escalator 10 and the manufacturer maintenance center device C1 via the wide area communication network NW, and the earthquake information management device C3 is communicatively connected to the manufacturer maintenance center device C1 via the wide area communication network NW.

[0014] 2 is a block diagram showing the configuration of a maintenance management system 1 according to one embodiment. An escalator 10 has an escalator communication unit (hereinafter referred to as an “ES communication unit”) 11 and an escalator control panel (hereinafter referred to as an “ES control panel”) 12.

[0015] The ES communication unit 11 communicates with the elevator cloud 30, the manufacturer maintenance center device C1, and the building disaster prevention center device C2 via the wide area communication network NW. The escalator control panel 12 controls the escalator 10 based on instructions from the elevator cloud 30.

[0016] The robot device 20 includes a device group 21, a movement mechanism 22, a robot communication unit 23, and a robot CPU 24.

[0017] The device group 21 includes a camera device 211 , an acceleration sensor 212 , a vibration sensor 213 , a sound collection device 214 , a speaker device 215 , a distance sensor 216 , an infrared sensor 217 , and an odor sensor 218 .

[0018] The movement mechanism 22 is a mechanism for moving the robot device 20. The robot communication unit 23 communicates with the elevator cloud 30 via the wide area communication network NW.

[0019] The robot CPU 24 is, for example, a CPU (Central Processing Unit) provided in a general-purpose microcomputer, and by installing and executing a predetermined robot control program, constitutes one or more information processing units shown below. The robot CPU 24 has a conveyor information acquisition unit 241, an operation control unit 242, a maintenance and inspection processing unit 243, a robot abnormality determination unit 244 as a moving body abnormality determination unit, an ES abnormality determination unit 245 as a passenger conveyor abnormality determination unit, and a restart possibility determination unit 246.

[0020] The conveyor information acquisition unit 241 acquires information about the escalator 10 acquired by each device in the device group 21 as status information of the escalator 10. The operation control unit 242 controls the moving mechanism 22. The maintenance and inspection processing unit 243 performs maintenance and inspection processing of the escalator 10 using the information acquired by the conveyor information acquisition unit 241.

[0021] The robot abnormality determination unit 244 determines whether an abnormality has occurred in its own robot device 20 based on the operating status of the devices in the device group 21 and the operating status of the moving mechanism 22 controlled by the operation control unit 242. If it is determined that no abnormality has occurred in the robot device 20, the ES abnormality determination unit 245 determines whether an abnormality has occurred in the escalator 10 based on the information acquired by the conveyor information acquisition unit 241.

[0022] The restart possibility determination unit 246 determines whether or not the maintenance and inspection work of the escalator 10 by the robot device 20 can be restarted based on the determination result of the ES abnormality determination unit 245. When the restart possibility determination unit 246 determines that the maintenance and inspection work can be restarted, it causes the maintenance and inspection processing unit 243 to restart the maintenance and inspection processing of the escalator 10.

[0023] The elevator cloud 30 includes a cloud communication unit 31 and a cloud CPU 32. The cloud communication unit 31 communicates with the escalator 10, the robot cloud 40, and the manufacturer maintenance center device C1.

[0024] The cloud CPU 32 is, for example, a CPU (Central Processing Unit) provided in a general-purpose microcomputer, and by installing and executing a predetermined escalator management program, configures one or more information processing units described below. The cloud CPU 32 has an operation monitoring unit 321, an earthquake occurrence detection unit 322, and an inspection monitoring unit 323.

[0025] The operation monitoring unit 321 monitors the operation status of the escalator 10. The earthquake occurrence detection unit 322 detects an earthquake when it occurs in an area including the building in which the escalator 10 is installed.

[0026] When the time for the monthly maintenance inspection of the escalator 10 arrives, for example, the inspection monitoring unit 323 causes the robotic device 20 to perform the maintenance inspection process of the escalator 10. When the earthquake occurrence detection unit 322 detects the occurrence of an earthquake during the maintenance inspection process of the escalator 10, the inspection monitoring unit 323 outputs a command to stop the operation of the robotic device 20 and the escalator 10, thereby stopping the maintenance inspection process, and thereafter, when it is determined that no abnormalities have occurred in the robotic device 20 or the escalator 10, it transmits an instruction to the robotic device 20 to resume the maintenance inspection.

[0027] <Operation of the maintenance management system according to one embodiment> 3 to 5 are sequence diagrams showing the operation of the maintenance management system 1 according to one embodiment. Under normal circumstances, the escalator 10 operates in a normal operation mode, and the operation monitoring unit 321 of the elevator cloud 30 acquires operating status information of the escalator 10 from the ES control panel 12 at predetermined time intervals via the cloud communication unit 31, the wide area communication network NW, and the ES communication unit 11. The operation monitoring unit 321 monitors the operating status of the escalator 10 by analyzing the acquired information.

[0028] When the inspection monitoring unit 323 of the elevator cloud 30 detects that the preset timing for performing maintenance and inspection processing of the escalator 10 has arrived, the inspection monitoring unit 323 transmits a maintenance and inspection start instruction to the ES control panel 12 (S1). When the ES control panel 12 receives the maintenance and inspection start instruction, the ES control panel 12 shifts the operation mode from the normal operation mode to the maintenance operation mode (S2).

[0029] The inspection monitoring unit 323 also transmits an instruction to the robot cloud 40 to start maintenance and inspection of the escalator 10 (S3). Upon receiving the instruction to start maintenance and inspection of the escalator 10, the robot cloud 40 transmits a movement instruction to the robot device 20 to instruct it to move to the escalator 10 to be inspected (S4).

[0030] When the robot device 20 receives the movement instruction, the operation control unit 242 controls the movement mechanism 22 to move to the vicinity of the escalator 10 to be inspected (S5). When the robot device 20 arrives near the escalator 10, the operation control unit 242 notifies the robot cloud 40 of this (S6). When the robot cloud 40 receives the notification from the robot device 20, it notifies the elevator cloud 30 that the robot device 20 has arrived near the escalator 10 (S7).

[0031] When the elevator cloud 30 receives the notification from the robot cloud 40, it sends an instruction to stop the escalator 10 to the ES control panel 12 (S8). When the ES control panel 12 receives the stop instruction, it stops the operation of the escalator 10 (S9).

[0032] In the robot device 20, the camera device 211 photographs the escalator 10, and the conveyor information acquisition unit 241 acquires the image information and sends it to the maintenance and inspection processing unit 243. When the maintenance and inspection processing unit 243 confirms that the operation of the escalator 10 has stopped based on the acquired image information, it operates the movement mechanism 22 using the operation control unit 242 to move the robot device 20 onto the steps of the escalator 10, and starts the maintenance and inspection processing (S10).

[0033] The maintenance and inspection processing unit 243 acquires status information of the escalator 10 acquired by the equipment in the equipment group 21 via the conveyor information acquisition unit 241, and uses the acquired status information to perform maintenance and inspection processes such as acquiring information about the appearance of the handrails, steps, boarding and alighting boards, ladder guards, and balustrades, acquiring information indicating the relative movement speed of the steps with respect to the handrails of the escalator 10, acquiring vibration information transmitted to the boarding and alighting boards or steps, and acquiring sound information around the robot device 20.

[0034] If a disaster occurs in the building where the escalator 10 is installed (for example, an earthquake occurs in the area including the building) while these maintenance and inspection processes are being performed, the building disaster prevention center device C2 or the earthquake information management device C3 detects this and notifies the manufacturer maintenance center device C1. The manufacturer maintenance center device C1 transmits the acquired information about the earthquake occurrence to the elevator cloud 30.

[0035] When elevator cloud 30 acquires information about the occurrence of an earthquake, it transmits an operation stop instruction to escalator 10 (S12). In escalator 10, ES control panel 12 acquires the operation stop instruction transmitted from elevator cloud 30 via ES communication unit 11, and ES control panel 12 stops the operation of escalator 10 (S13).

[0036] Furthermore, the elevator cloud 30 transmits a maintenance and inspection stop instruction to the robot cloud 40 (S14). The robot cloud 40 transmits the acquired maintenance and inspection stop instruction to the robot device 20 (S15). In the robot device 20, the maintenance and inspection processing unit 243 acquires the maintenance and inspection stop instruction acquired from the robot cloud 40 and stops the maintenance and inspection processing (S16). When the maintenance and inspection processing is stopped, the information acquisition processing by the conveyor information acquisition unit 241 for each device in the device group 21, which is related to the maintenance and inspection processing, is stopped, and the operation of the moving mechanism 22 by the operation control unit 242 is stopped.

[0037] After that, when a predetermined time (for example, 5 minutes) has elapsed since the maintenance and inspection process was stopped ("YES" in S17), the inspection monitor unit 323 of the elevator cloud 30 transmits a status check instruction to the robot cloud 40 (S18). The robot cloud 40 transmits the acquired status check instruction to the robot device 20 (S19).

[0038] When the robot device 20 receives a robot status confirmation instruction, the robot abnormality determination unit 244 starts the robot status confirmation process (S21) and determines whether or not an abnormality has been detected in the robot device 20 itself based on the operating status of the equipment in the equipment group 21 and the operating status of the movement mechanism 22 by the operation control unit 242 (S22).

[0039] An abnormality in the robot device 20 is detected, for example, when one of the devices in the equipment group 21 fails, or when the robot device 20 falls over on a step or board and is unable to maintain the posture required for maintenance and inspection.

[0040] If the robot abnormality determination unit 244 determines that no abnormality has been detected in its own robot device 20 ("NO" in S22), the ES abnormality determination unit 245 determines whether or not an abnormality such as damage has been detected in the escalator 10 based on the information acquired by the conveyor information acquisition unit 241 (S23).

[0041] If the ES abnormality determination unit 245 determines that no abnormality has been detected in the escalator 10 ("NO" in S23), the restart possibility determination unit 246 determines that the maintenance and inspection work of the escalator 10 by the robot device 20 can be restarted. If the ES abnormality determination unit 245 determines that the maintenance and inspection work of the escalator 10 can be restarted, it instructs the maintenance and inspection processing unit 243 to restart the maintenance and inspection processing of the escalator 10.

[0042] When the maintenance and inspection processing unit 243 receives the restart instruction, it restarts the maintenance and inspection processing (S24). At this time, the maintenance and inspection processing unit 243 may restart the maintenance and inspection processing from the beginning, or may restart the maintenance and inspection processing excluding the items that were completed before the earthquake occurred. When restarting the maintenance and inspection processing from the beginning, the maintenance and inspection processing unit 243 may delete the inspection information that was acquired before the earthquake occurred, or may store it as is and send it together with the inspection results to the manufacturer maintenance center device C1 via the elevator cloud 30 after the maintenance and inspection processing is completed.

[0043] When the maintenance and inspection processing unit 243 resumes the maintenance and inspection processing, it notifies the robot cloud 40 of this (S25). When the robot cloud 40 receives a notification of the resumption of the maintenance and inspection processing from the robotic device 20, it notifies the elevator cloud 30 of this (S26). From the notification received from the robot cloud 40, the elevator cloud 30 recognizes that the maintenance and inspection processing of the escalator 10 by the robotic device 20 has resumed (S27).

[0044] When the robot device 20 completes the maintenance and inspection process ("YES" in S28), it transmits the maintenance and inspection results to the robot cloud 40 (S29). The robot cloud 40 transmits the acquired maintenance and inspection results to the elevator cloud 30 (S30). In the elevator cloud 30, the inspection monitoring unit 323 receives the maintenance and inspection results (S31) and transmits them to the manufacturer maintenance center device C1. This allows the elevator cloud 30 to recognize the completion of the maintenance and inspection process.

[0045] When the elevator cloud 30 recognizes that the maintenance and inspection process for the escalator 10 has been completed, it transmits a maintenance and inspection completion notification to the ES control panel 12 (S32). When the ES control panel 12 receives the maintenance and inspection completion notification, it transitions the operation mode from the maintenance operation mode to the normal operation mode (S33).

[0046] In the above-mentioned step S22, if the robot abnormality determination unit 244 determines that an abnormality has been detected in its own robotic device 20 ("YES" in S22), it notifies the robot cloud 40 of this. The robot cloud 40 notifies the elevator cloud 30 of the acquired information on the abnormality detection in the robotic device 20 (S34). When the elevator cloud 30 acquires the notification of the abnormality detection in the robotic device 20, it issues a report to the manufacturer maintenance center device C1 or the building disaster prevention center device C2 (S35). When these devices receive the report, a maintenance worker or a manager of the building management center or the like goes to the escalator 10 and performs work to retrieve the robotic device 20.

[0047] When the inspection monitoring unit 323 of the elevator cloud 30 receives a notification that an abnormality has been detected in the robotic device 20, it may send an instruction to the escalator 10 to move the steps of the escalator 10 downward, and by moving the steps, the robotic device 20 may be moved to a location near the lower entrance. If the robotic device 20 is left stopped on the steps until a maintenance worker arrives, there is a possibility that it may fall downward and be damaged in the event of an aftershock, but this can be prevented by moving it to a location near the lower entrance.

[0048] Furthermore, if the position of the step where the robotic device 20 is stopped is closer to an upper exit than to a lower entrance in the escalator 10 or is within a predetermined distance from the upper exit, and the length of the step that becomes horizontal just before the upper exit is equal to or greater than a predetermined value (for example, three steps or more), the inspection monitoring unit 323 may move the steps of the escalator 10 upward to move the robotic device 20 closer to the upper exit. This allows the robotic device 20 to be moved efficiently to a safe position.

[0049] Furthermore, in step S23, if the ES abnormality determination unit 245 detects an abnormality in the escalator 10 ("YES" in S23), it notifies the robot cloud 40. The robot cloud 40 notifies the elevator cloud 30 of the acquired information about the abnormality in the escalator 10 (S36). When the elevator cloud 30 acquires the notification of the abnormality in the escalator 10, it issues a report to the manufacturer maintenance center device C1 or the building disaster prevention center device C2 (S37). When these devices receive the report, a maintenance worker goes to the escalator 10 and performs the work of retrieving the robot device 20 and the work of maintaining the escalator 10.

[0050] In step S19 of the above-described embodiment, when the elevator cloud 30 sends a status check instruction to the robot cloud 40, it may also send a status check instruction to the ES control panel 12, causing the ES control panel 12 to check the status of the escalator 10.

[0051] In this case, when the robot device 20 checks its own status and determines that no abnormality has been detected, it transmits this determination result to the ES control panel 12 via the robot cloud 40 and the elevator cloud 30. When the ES control panel 12 obtains a determination result indicating that no abnormality has been detected in the robot device 20, it requests ES status information from the robot device 20 via the elevator cloud 30 and the robot cloud 40.

[0052] When the robot device 20 acquires the ES status information request transmitted from the ES control panel 12, the ES abnormality determination unit 245 responds by transmitting the information of each device in the device group 21 acquired by the conveyor information acquisition unit 241 to the ES control panel 12. The ES control panel 12 analyzes the information of each device acquired from the robot device 20 and determines whether or not there is a malfunction in the switches installed in the ES control panel 12 by causing the escalator 10 to perform a fault diagnosis operation, and determines whether or not there is an abnormality in the escalator 10 based on this information.

[0053] When the escalator 10 determines that there is no abnormality in the escalator 10 itself, it notifies the robotic device 20 of this fact. When the robotic device 20 receives the notification that there is no abnormality in the escalator 10, it resumes the maintenance and inspection process.

[0054] Alternatively, the elevator cloud 30 may acquire information acquired by the robot device 20 from the equipment in the equipment group 21 and information acquired by the ES control panel 12, and based on this, the elevator cloud 30 may determine whether an abnormality has occurred in the robot device 20 and the escalator 10.

[0055] Furthermore, in the above-described embodiment, when the elevator cloud 30 performs the status check process for the robot device 20 and the escalator 10, it may obtain image information from a surveillance camera installed in the building from the building disaster prevention center device C2 via the manufacturer maintenance center device C1 and the elevator cloud 30, and use the obtained image information to check the status.

[0056] In step S17 of the above-described embodiment, the robot device 20 may detect the occurrence of an earthquake using an earthquake detection sensor (not shown) within the robot device 20, and may stop the maintenance and inspection process based on this.

[0057] Furthermore, in step S22 of the above-described embodiment, when an abnormality in the robot device 20 is detected, the presence or absence of restarting the subsequent maintenance and inspection process and the execution content if restarted may be changed depending on the content of the abnormality.

[0058] For example, even if a faulty device is detected in the device group 21 of the robot device 20, if this device does not affect the maintenance and inspection process, if it can be substituted with other devices, or if the maintenance and inspection process can be performed with some of the devices, the ES abnormality determination unit 245 may determine that the maintenance and inspection process can be resumed despite the abnormality and may resume the process. In this case, when the maintenance and inspection process is resumed, the maintenance and inspection process is resumed using only information that can be obtained from devices that are operating normally. Also, if only the movement mechanism 22 of the robot device 20 is faulty, the maintenance and inspection process may be performed while the robot device is stopped on the steps.

[0059] Furthermore, in the above-described embodiment, if the robot device 20 is configured to perform maintenance inspections of multiple escalators including the escalator 10, after transmitting the maintenance inspection results in step S29, the robot device 20 moves toward the next escalator to be inspected and performs the maintenance inspection process in the same manner.

[0060] Furthermore, if there are multiple robotic devices managed by the robot cloud 40 in a building, in step S34 of the above-described embodiment, when the robotic cloud 40 notifies the elevator cloud 30 of an abnormality in the robotic device 20, the elevator cloud 30 may send instructions to the other robotic devices to check the status of the escalator 10 and perform maintenance and inspection processing.

[0061] The robot device 20 may be rented by the building management center from the escalator manufacturer, may be owned by the building management center, or may be owned by the robot manufacturer.

[0062] In the above-described embodiment, information communication between the escalator 10 and the robot device 20 is performed via the elevator cloud 30 and the robot cloud 40, but the escalator 10 and the robot device 20 may be configured to be able to communicate with each other via short-range wireless communication or the like, and information may be sent and received directly.

[0063] In the above-described embodiment, the maintenance management system 1 has been described as executing a process when an earthquake occurs while the conveyor information acquisition unit 241 of the robotic device 20 is acquiring status information of the escalator 10. However, the present invention is not limited to this, and the maintenance management system 1 may execute a similar process when a disaster other than an earthquake occurs, for example, when a building is shaken by strong winds and there is a risk that the robotic device 20 may fall over, or when a fire or a water leak occurs in the water facility and there is a risk that the robotic device 20 may come into contact with a fleeing user and fall over.

[0064] [Effects of the embodiment] According to the above-described embodiment, the mobile body includes a conveyor information acquisition unit that acquires status information of a passenger conveyor that is a maintenance inspection target, and a maintenance inspection processing unit that, when acquiring disaster occurrence information while the conveyor information acquisition unit is acquiring status information of the passenger conveyor for maintenance inspection processing, stops the acquisition process of the status information of the passenger conveyor, and thereafter, when recognizing that no abnormality has been detected in the mobile body or the passenger conveyor, causes the conveyor information acquisition unit to resume the acquisition process of the status information of the passenger conveyor. Here, the "mobile body" refers to the mobile body main body that includes the conveyor information acquisition unit and the maintenance inspection processing unit.

[0065] This allows for the maintenance and inspection process to be automatically and safely resumed when a disaster occurs during maintenance and inspection of a passenger conveyor using a moving body, thereby reducing the workload of maintenance workers.

[0066] The mobile body may also include at least one of a camera device, an acceleration sensor, a vibration sensor, a sound collection device, a speaker device, a distance sensor, an infrared sensor, and an odor sensor, and the conveyor information acquisition unit may acquire information acquired by the device as status information of the passenger conveyor. This allows the mobile body to acquire detailed status information of the passenger conveyor based on various information.

[0067] The maintenance and inspection processing unit may also perform the maintenance and inspection process using the status information of the passenger conveyor acquired by the conveyor information acquisition unit. This eliminates the need for the passenger conveyor maintenance and management process to be performed by the passenger conveyor or a passenger conveyor maintenance and management device, thereby reducing the load on these devices.

[0068] The mobile body may further include a mobile body abnormality determination unit that determines whether an abnormality in the mobile body has been detected when disaster occurrence information is acquired, and a passenger conveyor abnormality determination unit that determines whether an abnormality in the passenger conveyor has been detected when the mobile body abnormality determination unit determines that an abnormality in the mobile body has not been detected, and the maintenance and inspection processing unit may recognize that no abnormality in the mobile body or the passenger conveyor has been detected when the passenger conveyor abnormality determination unit determines that an abnormality in the passenger conveyor has not been detected. This eliminates the need for the passenger conveyor or the passenger conveyor maintenance management device to perform processing to acquire status information about the mobile body and the passenger conveyor when a disaster occurs, thereby reducing the load on these devices.

[0069] The maintenance management system also includes a passenger conveyor to be inspected for maintenance and inspection, an autonomously movable vehicle, and a maintenance management device communicatively connected to the passenger conveyor and the movable vehicle. The movable vehicle includes a conveyor information acquisition unit that acquires status information of the passenger conveyor to be inspected for maintenance and inspection, and a maintenance and inspection processing unit that, when acquiring disaster occurrence information while the conveyor information acquisition unit is acquiring status information of the passenger conveyor for maintenance and inspection processing, stops the acquisition of status information of the passenger conveyor, and subsequently causes the conveyor information acquisition unit to resume the acquisition of status information of the passenger conveyor when it recognizes that no abnormalities in the movable vehicle or the passenger conveyor are detected by the status check processing executed based on a status check instruction output from the maintenance and inspection device. The passenger conveyor also includes a control panel that stops operation when disaster occurrence information is acquired during operation. The maintenance management device also includes an inspection monitoring unit that sends a status check instruction to the movable vehicle after the acquisition of status information of the passenger conveyor by the movable vehicle and the operation of the passenger conveyor are stopped due to the occurrence of a disaster.

[0070] This means that if a disaster occurs during maintenance and inspection of a passenger conveyor using a moving body and the maintenance and inspection process is interrupted, the maintenance and inspection process can be automatically and safely resumed, reducing the workload of maintenance workers.

[0071] Furthermore, when the inspection monitoring unit receives a notification of the detection of an abnormality in the moving body by sending the status check instruction, the inspection monitoring unit may move the moving body to the entrance or exit of the passenger conveyor by moving the steps of the passenger conveyor. This makes it possible to prevent the moving body from falling and being further damaged, even if an aftershock occurs before a maintenance inspector comes to retrieve the malfunctioning moving body.

[0072] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
