Description

[Technical Field]

[0001] The present disclosure relates to a passenger conveyor inspection system and a communication setting method for the passenger conveyor inspection system. [Background technology]

[0002] Conventionally, each host connected to the network of an elevator system, which is a mobile system within a building, has its IP address (Internet Protocol Address) set using DHCP (Dynamic Host Configuration Protocol), or the IP address has been set manually without using DHCP (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-052935 Summary of the Invention [Problem to be solved by the invention]

[0004] When rewriting a specific IP address for each inspection device installed in the escalator machine room, the setting is done manually as shown in Patent Document 1, but this requires an operator to directly operate a switch on the inspection device installed inside the machine room, which poses the problem of requiring a lot of effort to rewrite the IP address of each inspection device.

[0005] The present disclosure has been made to solve the above-mentioned problems, and aims to provide a passenger conveyor inspection system that can easily rewrite a specific IP address for each inspection device, and a communication setting method for a passenger conveyor inspection system. [Means for solving the problem]

[0006] A passenger conveyor inspection system according to the present disclosure includes a management device having a management memory unit, one or more inspection devices installed corresponding to one or more passenger conveyors, and a network connecting the management device and each inspection device so that they can communicate with each other. The management memory unit stores a specific IP address corresponding to each inspection device, and each inspection device has an inspection input / output unit to which a signal output by an operation device installed on the passenger conveyor corresponding to each inspection device is input. The management device can rewrite the IP addresses of the management device and each inspection device to primary IP addresses to enable communication between the management device and each inspection device. Each inspection device can send an IP address rewrite request signal to the management device in response to the signal. The management device can rewrite the IP address of the inspection device that sent the IP address rewrite request signal from the primary IP address to a specific IP address. The specific IP address is extracted by the inspection device from the specific IP addresses stored in the management memory unit. The management device can send the extracted specific IP address to the inspection device that sent the IP address rewrite request signal. An inspection device that receives the specific IP address extracted by the management device can rewrite its own IP address to the received specific IP address. [Effects of the Invention]

[0007] According to the passenger conveyor inspection system and the communication setting method for the passenger conveyor inspection system disclosed herein, the IP address of the inspection device can be easily rewritten to a specific IP address. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments will be described with reference to the drawings. Embodiment 1 FIG. 1 is a schematic diagram showing the entire passenger conveyor inspection system 100 according to the first embodiment. The passenger conveyor in the first embodiment is an escalator 1. The passenger conveyor inspection system 100 is a system that collects and stores information about eight escalators 1A to 1H under its jurisdiction. In this embodiment, the eight escalators 1A to 1H under its jurisdiction are installed inside a building.

[0010] The passenger conveyor inspection system 100 includes a management device 110, 16 inspection devices 120LA to 120UH, and a network 130. The management device 110 and the 16 inspection devices 120LA to 120UH are connected to the network 130, thereby enabling communication with each other.

[0011] Management device 110 is installed inside a building and is capable of collecting information on eight escalators 1A to 1H under its jurisdiction. Fig. 2 is a schematic diagram showing management device 110 of Fig. 1. Management device 110 has a management control unit 110a, a management storage unit 110b, and a management input / output unit 110c.

[0012] The management control unit 110a performs calculations based on the information stored in the management memory unit 110b and the information input via the management input / output unit 110c, and can output commands and information necessary for other devices via the management input / output unit 110c.

[0013] Returning to Figure 1, the explanation will continue. Two inspection devices 120 are installed for one escalator 1. Each inspection device 120 is installed inside the machine room 6 of the escalator 1. The machine room 6 will be explained later.

[0014] Fig. 3 is a schematic diagram showing the inspection devices 120 of Fig. 1. Each inspection device 120 has an inspection control unit 120a, an inspection memory unit 120b, and an inspection input / output unit 120c. The inspection control unit 120a can communicate information with other inspection devices 120 and the management device 110 via the inspection input / output unit 120c.

[0015] Each inspection device 120 receives signals from multiple sensors (not shown) installed on the corresponding escalator 1, images captured by a photographing mechanism (not shown), and signals from multiple operating devices installed on the corresponding escalator 1 via the inspection input / output unit 120c.

[0016] The multiple sensors are, for example, microphones that collect the operating sounds of the escalator 1 and environmental sounds around the escalator 1, and sensors that detect slack in the handrail chains used on the escalator 1. The photographing mechanism can photograph a corresponding part of the escalator 1.

[0017] Returning to Fig. 1, the explanation will be continued. The network 130 is constructed with wiring capable of information communication. The network 130 is made up of wiring such as LAN wiring (Local Area Network wiring) and power wiring. In this embodiment, the network 130 is constructed with physical wiring, but part or all of the network may be constructed wirelessly.

[0018] The passenger conveyor inspection system 100 is connected to a server 200 so as to be able to communicate information with the server 200 via an internet line 210. The management device 110 and the server 200 are connected by the internet line 210, for example, using an LTE line (Long Term Evolution line) or an optical cable.

[0019] The server 200 can collect and store information about the escalators 1A to 1H collected and stored by the management device 110. A plurality of computer terminals (not shown) can be connected to the server 200 via an internet line 210 so as to be able to communicate with each other. It has been done.

[0020] By accessing the server 200 using a computer terminal, a worker can view the information about each of the escalators 1A to 1H stored in the server 200 and download it to the computer terminal to obtain it. Using the computer terminal, the worker can perform tasks such as creating documents such as slips and reports, and creating websites to display information, based on the obtained information.

[0021] FIG. 4 is a schematic diagram showing the side of the escalator 1 in FIG. 1. The escalator 1 is installed between an upper floor UF and a lower floor LF. The escalator 1 has a pair of balustrades 2 and a plurality of steps 4 that move between the pair of balustrades 2. Passengers who board the steps 4 can move from the upper floor UF to the lower floor LF, or from the lower floor LF to the upper floor UF, as the steps 4 move.

[0022] At the end of the lower floor LF of the escalator 1, there is provided a lower boarding / alighting entrance 5L for passengers to board or disembark from the escalator 1. A lower machine room 6L is provided below the floor of the lower boarding / alighting entrance 5L. A lower inspection device 120L is installed in the lower machine room 6L.

[0023] An upper entrance / exit 5U is provided at the end of the upper floor UF of the escalator 1, allowing passengers to board or disembark from the escalator 1. An upper machine room 6U is provided below the floor of the upper entrance / exit 5U. An upper inspection device 120U is installed in the upper machine room 6U.

[0024] A lower operating unit 10L is installed near the end on the lower floor LF side of one of the balustrades 2. An upper operating unit 10U is installed near the end on the upper floor UF side of the balustrade 2 where the lower operating unit 10L is installed. The lower operating unit 10L and the upper operating unit 10U are installed facing the steps 4 side.

[0025] The upper operation unit 10U and the lower operation unit 10L shown in Fig. 4 have the same configuration, and therefore will be described as operation unit 10. Fig. 5 is a schematic diagram showing operation unit 10 provided on escalator 1 in Fig. 4. Operation unit 10 includes an operation key switch 11, an operation direction switching key switch 12, and an emergency stop button 15 as operation devices.

[0026] Each of the operation devices installed in the operation unit 10 is connected to a corresponding inspection device 120 via a signal line. Therefore, the signals of each of the operation devices are input to the corresponding inspection device 120. That is, each signal of the operation devices installed in the upper operation unit 10U installed on the upper floor UF side of the escalator 1 is input to an upper inspection device 120U installed in the upper machine room 6U provided on the upper floor UF side.

[0027] Key switches such as the operation key switch 11 and the operation direction switching key switch 12 can be operated by inserting a dedicated key into the keyhole of the key switch itself. By operating the operation key switch 11, the operation state of the escalator 1 can be selected to either start or stop. By operating the operation direction switching key switch 12, the movement direction of the escalator 1 can be selected to either up or down. By pressing the emergency stop button 15, the escalator 1 can be put into an emergency stop state.

[0028] In this disclosure, for components installed on the lower floor LF, the prefix "lower" is added to the name of the component, and the reference numeral of the component is further appended with L. For components installed on the upper floor UF, the prefix "upper" is added to the name of the component, and the reference numeral of the component is further appended with U. For components installed corresponding to escalators 1 No. 1 to No. 8, the prefixes "No. 1" to "No. 8" are added to the name of the component, and the reference numeral of the component is further appended with A to H.

[0029] For example, the machine room 6 installed on the upper floor UF of the No. 8 escalator 1 is the No. 8 upper machine room 6UH. Inside the No. 8 upper machine room 6UH, the No. 8 upper inspection device 120UH is arranged.

[0030] Next, a description will be given of a communication setting method for the passenger conveyor inspection system 100. Fig. 6 is a flow chart showing a communication setting method for the passenger conveyor inspection system 100 of Fig. 1.

[0031] In the communication setting method for the passenger conveyor inspection system 100, the IP addresses of the management device 110 and the 16 inspection devices 120 are rewritten to specific IP addresses, which are specific IP addresses, to enable communication between them.

[0032] The rewriting order, which is the order in which the IP addresses for each inspection device 120 are rewritten to specific IP addresses, is predetermined. Here, the rewriting order is set to, from the beginning, the No. 1 lower inspection device 120LA, the No. 1 upper inspection device 120UA, the No. 2 lower inspection device 120LB, the No. 2 upper inspection device 120UB, the No. 3 lower inspection device 120LC, the No. 3 upper inspection device 120UC, the No. 4 lower inspection device 120LD, the No. 4 upper inspection device 120UD, the No. 5 lower inspection device 120LE, the No. 5 upper inspection device 120UE, the No. 6 lower inspection device 120LF, the No. 6 upper inspection device 120UF, the No. 7 lower inspection device 120LG, the No. 7 upper inspection device 120UG, the No. 8 lower inspection device 120LH, and the No. 8 upper inspection device 120UH.

[0033] First, a preparation step in step S01 is performed. In the preparation step, the passenger conveyor inspection system 100 is constructed. Specifically, the management device 110, 16 inspection devices 120, and network 130 are installed, the management device 110 and the 16 inspection devices 120 are connected to the network 130, and the management device 110 and the 16 inspection devices 120 are powered on.

[0034] After the preparation step of step S01, a primary communication setup step of step S02 is carried out. In the primary communication setup step, the management device 110 and each of the 16 inspection devices 120 are set to be able to communicate with each other.

[0035] In the primary communication setup process, the management device 110 rewrites the IP addresses of the management device 110 and each of the 16 inspection devices 120 from their initially set IP addresses to primary IP addresses. The primary IP addresses assigned in the primary communication setup process are dynamic IP addresses, and are IP addresses determined by the management device 110.

[0036] The management device 110 has a DHCP server function and can assign dynamic IP addresses to the management device 110 and each inspection device 120 connected to the network 130. This allows the management device 110 and the 16 inspection devices 120 to communicate with each other using primary IP addresses.

[0037] After the primary communication setting process in step S02, a specific IP address rewriting process in step S03 is carried out. In the specific IP address rewriting process, the IP addresses of the management device 110 and each of the inspection devices 120 are rewritten to specific IP addresses, and the devices are connected so that they can communicate with each other. The specific IP addresses are specific IP addresses assigned to the management device 110 and the 16 inspection devices 120, as determined by the designer of the passenger conveyor inspection system 100.

[0038] The management device 110 and 17 specific IP addresses corresponding to each of the 16 inspection devices 120 are stored in advance in the management storage unit 110b. When the specific IP address corresponding to the management device 110 is defined as the management device specific IP address, each specific IP address other than the management device specific IP address is associated with the IP address rewrite order and stored in the management storage unit 110b. Each specific IP address is input to the management device 110 by an operator using an interface device (not shown) and is stored in the management storage unit 110b.

[0039] First, based on an instruction from an operator, the management device 110 transitions from normal mode to specific IP address rewriting mode. The operator inputs an instruction to transition to specific IP address rewriting mode to the management device 110, for example, using an interface device (not shown). As a result, the management device 110 and each inspection device 120 transition from operation mode to specific IP address rewriting mode.

[0040] When the management device 110 shifts to the specific IP address rewrite mode, the management device 110 first extracts from the management storage unit 110b the management device specific IP address to be rewritten as its own IP address.

[0041] The management device 110 rewrites its own IP address to the extracted management device specific IP address and resumes communication with each inspection device 120. After confirming that communication has been established using the management device specific IP address, the management device 110 prompts the worker to proceed to the next task.

[0042] The management device 110 knows which inspection device 120 should be rewritten next according to the IP address rewriting order described above. Therefore, the management device 110 may display a message such as "Please operate the operating device of the No. 1 lower inspection device" on a display device (not shown) connected to the management device 110 to prompt the worker to perform the next task.

[0043] The worker performs a specific operation on the operation device on the No. 1 lower operation unit 10LA connected to the No. 1 lower inspection device 120LA. In this embodiment, the specific operation on the operation device is to press the emergency stop button 15.

[0044] The signal from the emergency stop button 15 is input to the No. 1 lower inspection device 120LA. In the specific IP address rewrite mode, when the emergency stop button 15 is pressed, the No. 1 lower inspection device 120LA transmits an IP address rewrite request signal to the management device 110 via the network 130 based on the signal indicating that the emergency stop button 15 has been pressed.

[0045] In this embodiment, the IP address rewrite request signal is the IP address of the inspection device 120 that transmitted the IP address rewrite request signal. This IP address is a primary IP address.

[0046] By receiving the IP address as an IP address rewrite request signal, the management device 110 can identify the inspection device 120 whose IP address should be rewritten.

[0047] The management device 110 extracts the specific IP address associated with the first in the rewrite order from the management storage unit 110b. That is, the extracted specific IP address is the specific IP address to be assigned to the first lower inspection device 120LA, which is the inspection device 120 associated with the first in the rewrite order.

[0048] The management device 110 transmits the extracted specific IP address to the device (No. 1 lower inspection device 120LA) having the IP address that is the IP address rewrite request signal, and issues a command to rewrite the IP address of the device from the primary IP address to the transmitted specific IP address. Note that the management device 110 issues a command to rewrite the IP address from the primary IP address to the transmitted specific IP address, but is not limited to this.

[0049] For example, the management device 110 may not issue a command to rewrite the IP address of the device from the primary IP address to the specific IP address that was sent. In this case, the management device 110 may instead issue a command to rewrite the IP address to the specific IP address by sending the specific IP address to the device having the IP address that is the IP address rewrite request signal.

[0050] The No. 1 lower inspection device 120LA rewrites its own IP address to the specific IP address sent from the primary IP address and resumes communication with the management device 110. The management device 110 confirms that the IP address of the No. 1 lower inspection device 120LA has been rewritten to the specific IP address. In order for the management device 110 to confirm that the IP address of the No. 1 lower inspection device 120LA has been rewritten to the specific IP address, the No. 1 lower inspection device 120LA may send a signal indicating that it has been rewritten to the specific IP address.

[0051] The management device 110 reports to the worker that the IP address of the No. 1 lower inspection device 120LA has been rewritten to a specific IP address, and urges the worker to rewrite the IP address of the next inspection device 120, i.e., the No. 1 upper inspection device 120UA, to the specific IP address.

[0052] After resetting the emergency stop button 15 on the No. 1 lower operation unit 10LA, the worker presses the emergency stop button 15 on the No. 1 upper operation unit 10UA. As a result, a signal from the emergency stop button 15 corresponding to the No. 1 upper inspection device 120UA is input to the No. 1 upper inspection device 120UA, and an IP address rewrite request signal is transmitted from the No. 1 upper inspection device 120UA to the management device 110 via the network 130.

[0053] After the management device 110 has completed rewriting the specific IP address of the No. 1 lower inspection device 120LA, it determines that the next inspection device 120 to send an IP address rewrite request signal is the inspection device 120 that is second in the rewrite order.

[0054] Management device 110 extracts the specific IP address associated second in the rewrite order from management storage unit 110b. Management device 110 transmits the extracted specific IP address to inspection device 120 that transmitted the IP address rewrite request signal, and issues a command to rewrite the IP address of inspection device 120 from the primary IP address to the transmitted specific IP address.

[0055] The No. 1 upper inspection device 120UA rewrites its own IP address to the specific IP address sent from the primary IP address and resumes communication with the management device 110. The management device 110 confirms that the IP address of the No. 1 upper inspection device 120UA has been rewritten to the specific IP address.

[0056] The management device 110 reports to the worker that the IP address of the No. 1 upper inspection device 120UA has been rewritten to a specific IP address, and urges the worker to rewrite the IP address of the next inspection device 120, the No. 2 lower inspection device 120LB, to a specific IP address.

[0057] In this way, the management device 110 sequentially transmits the specific IP addresses extracted according to the determined rewrite order to the inspection device 120 that sent the IP address rewrite request signal, and commands the inspection device 120 to rewrite the IP address to the specific IP address. This is repeated according to the rewrite order, and when the IP address of the last inspection device 120UH on No. 8 is rewritten to the specific IP address, the specific IP address rewrite process of step S02 is completed.

[0058] After the specific IP address rewriting process of step S03, a health check process of step S04 is performed. With the IP address of the management device 110 and the IP addresses of each inspection device 120 rewritten from the primary IP address to the specific IP address, the management device 110 performs a health check on each inspection device 120. The health check is a test to determine whether the functions of each inspection device 120 and communication with each inspection device 120 are sound. If the health check confirms that there are no problems, the management device 110 and each inspection device 120 return to normal mode from the specific IP address rewriting mode, and the health check process ends.

[0059] This completes the communication settings between the management device 110 and each inspection device 120, and the management device 110 and each inspection device 120 can communicate with each other using the specific IP address.

[0060] If a problem is found in the health check, the management device 110 reports this to the operator and terminates the communication setup between the management device 110 and each inspection device 120. This causes the management device 110 and each inspection device 120 to return from the specific IP address rewrite mode to the normal mode, and the health check process ends. The operator then finds the problem in the health check, repairs it, and sets up the communication again.

[0061] 7 is a configuration diagram showing a first example of a processing circuit that realizes the functions of the management device 110 and each inspection device 120 in FIG. 1. The functions of the control devices of the management device 110 and each inspection device 120 are realized by suitable processing circuits. The processing circuit 300 in the first example is dedicated hardware.

[0062] Furthermore, the processing circuit 300 may be, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination thereof.

[0063] 8 is a configuration diagram showing a second example of a processing circuit that realizes the functions of the management device 110 and each inspection device 120 in FIG. 1. The processing circuit 310 of the second example includes a processor 311 and a memory 312.

[0064] In the processing circuit 310, the functions of the management device 110 and each inspection device 120 are realized by software, firmware, or a combination of software and firmware. The software and firmware are written as programs and stored in the memory 312. The processor 311 realizes the functions by reading and executing the programs recorded in the memory 312.

[0065] It can also be said that the programs stored in memory 312 cause the computer to execute the procedures or methods of the above-mentioned sections. Here, memory 312 refers to non-volatile or volatile semiconductor memory, such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EPROM (Erasable Programmable Read Only Memory), and EEPROM (Electrically Erasable and Programmable Read Only Memory). Magnetic disks, flexible disks, optical disks, compact disks, minidisks, DVDs, and the like also fall under memory 312.

[0066] It should be noted that the functions of the management device 110 and each inspection device 120 described above may be partially realized by dedicated hardware and partially realized by software or firmware.

[0067] Thus, the processing circuitry may implement the functionality of the passenger conveyor inspection system 100 described above through hardware, software, firmware, or a combination thereof.

[0068] The passenger conveyor inspection system 100 according to the first embodiment includes a management device 110, one or more inspection devices 120, and a network 130. The management device 110 includes a management storage unit 110b. The one or more inspection devices 120 are installed corresponding to one or more escalators 1. The network 130 connects the management device 110 and each of the inspection devices 120 so that they can communicate with each other. The management storage unit 110b stores a specific IP address corresponding to each of the inspection devices 120. Each of the inspection devices 120 includes an inspection input / output unit that receives a signal output by an operation device installed on the escalator 1 corresponding to the inspection device 120. The management device 110 can rewrite the IP addresses of the management device 110 and each of the inspection devices 120 to primary IP addresses, thereby enabling communication between the management device 110 and each of the inspection devices 120. Furthermore, each inspection device 120 can transmit an IP address rewrite request signal to the management device 110 in response to the signal. Furthermore, the management device 110 can rewrite the IP address of the inspection device 120 that transmitted the IP address rewrite request signal from a primary IP address to a specific IP address. The specific IP address is obtained by extracting each specific IP address stored in the management memory unit 110b by the management device 110. Furthermore, the management device 110 can transmit the extracted specific IP address to the inspection device 120 that transmitted the IP address rewrite request signal. The inspection device 120 that receives the specific IP address extracted by the management device 110 can rewrite its own IP address to the received specific IP address. This allows the management device 110 to rewrite the IP address of each inspection device 120 to the corresponding specific IP address through communication between the management device 110 and each inspection device 120, eliminating the need to manually input the specific IP address into each inspection device 120. Therefore, the IP address of the inspection device 120 can be easily rewritten to the specific IP address. Furthermore, by operating an operation device installed on the escalator 1, it is possible to identify the inspection device 120 whose IP address should be rewritten.Therefore, the worker can easily rewrite the IP address of the inspection device 120 to a specific IP address without having to access the inspection device 120 installed in the machine room 6. Furthermore, since the specific IP address is rewritten using an operation device installed on the escalator 1, the worker does not need to physically operate the operation device, which improves security.

[0069] In the passenger conveyor inspection system 100 according to the first embodiment, the specific IP addresses stored in the management storage unit 110b are stored in association with a predetermined rewrite order. The specific IP addresses are extracted from the specific IP addresses associated with a rewrite order corresponding to the order in which IP address rewrite request signals are received from the inspection devices 120. The rewrite order is the order in which IP addresses are rewritten to specific IP addresses for one or more inspection devices 120. By storing each specific IP address in association with the rewrite order, the IP address of a desired inspection device 120 can be rewritten to the specific IP address. Therefore, the IP addresses of all inspection devices 120 can be more easily rewritten to specific IP addresses.

[0070] In the passenger conveyor inspection system 100 according to the first embodiment, each operation device is installed on the balustrade 2 of the corresponding escalator 1. This eliminates the need for an operator to go inside the machine room 6 where each inspection device 120 is installed, and makes it easier to rewrite the IP address of the inspection device 120 to a specific IP address.

[0071] The communication setup method for the passenger conveyor inspection system of the escalator 1 according to the first embodiment includes a preparation step, a primary communication setup step performed after the preparation step, and a specific IP address rewriting step performed after the primary communication setup step. The preparation step includes preparing the passenger conveyor inspection system 100. The primary communication setup step includes connecting the management device 110 and each inspection device 120 so that they can communicate with each other. The specific IP address rewriting step includes rewriting the IP addresses of each of the one or more inspection devices 120 from primary IP addresses to specific IP addresses. The specific IP address rewriting step also includes establishing communication with all of the inspection devices 120 after the IP addresses of the inspection devices 120 have been rewritten from primary IP addresses to specific IP addresses. This allows the management device 110 to rewrite the IP addresses of each inspection device 120 to the corresponding specific IP addresses through communication between the management device 110 and each inspection device 120, eliminating the need to manually input the specific IP addresses into each inspection device 120. Therefore, the IP addresses of the inspection devices 120 can be easily rewritten to specific IP addresses.

[0072] In the passenger conveyor inspection system 100 according to the first embodiment, the multiple specific IP addresses associated with the rewrite order are input by an operator to the management device 110 using an interface device (not shown) and stored in the management storage unit 110b. However, this is not a limitation. For example, the multiple specific IP addresses associated with the rewrite order may be input from the server 200 to the management device 110 via the Internet line 210. Furthermore, an operator may input a desired specific IP address from the server 200 to the management device 110 using a computer terminal connected to the server 200. In this case, the management control unit 110a stores the multiple specific IP addresses associated with the rewrite order input via the server 200 in the management storage unit 110b. This allows the operator to input the multiple specific IP addresses associated with the rewrite order to the management device 110 from a location physically distant from the management device 110, thereby improving convenience for the operator.

[0073] In the passenger conveyor inspection system 100 according to the first embodiment, the management device 110 is communicatively connected to the server 200, and the server 200 can input one or more specific IP addresses associated with a rewrite order to the management device 110. The management device 110 can also store the one or more specific IP addresses associated with the rewrite order input from the server 200 in the management storage unit 110b. This eliminates the need to input the specific IP addresses on-site, such as in a building, and allows the specific IP addresses to be stored in advance in the management storage unit 110b via the server 200, for example. This makes it easier to rewrite the IP address of the inspection device 120 to a specific IP address.

[0074] Furthermore, server 200 in the first embodiment is connected to one passenger conveyor inspection system 100 via internet line 210. However, this is not limited to this. One or more passenger conveyor inspection systems 100 installed in each of a plurality of jurisdictions may be connected to server 200 via internet line 210. This allows an operator to access server 200 and grasp the status of each escalator 1 managed by each of the plurality of passenger conveyor inspection systems 100.

[0075] Furthermore, in the passenger conveyor inspection system 100 of the first embodiment, the specific operation on the operation device is the operation of pressing the emergency stop button 15. However, this is not limited to this. For example, the specific operation on the operation device may be the operation of selecting either drive or stop on the operation key switch 11, or the operation of selecting either up or down on the operation direction switching key switch 12. In this case, it is necessary that the initial selection state of all operation key switches 11 or all operation direction switching key switches 12 installed on other escalators 1 is a state in which the same option is selected. Also, for example, the operation may be the operation of operating key switches 11, operation direction switching key switches 12, and emergency stop button 15 in a specific order. In this case, by making the operation order of each operation device known only to the worker, it is possible to ensure that only the worker can rewrite the specific IP address. This improves the safety of the work.

[0076] In the passenger conveyor inspection system 100 according to the first embodiment, each operation device is a key switch related to the operation of the corresponding escalator 1. Furthermore, when the management device 110 and each inspection device 120 are in a specific IP address rewrite mode, each inspection device 120 can transmit an IP address rewrite request signal to the management device 110 in response to a signal from the key switch. This eliminates the need to provide a special switch for the inspection device 120. Furthermore, by using a key corresponding to the key switch related to the operation of the escalator 1, only those who possess the key can rewrite the IP address to a specific IP address, thereby further improving security. Furthermore, the key switch related to the operation of the corresponding escalator 1 is used as the operation device. Therefore, a worker need only operate the key switch installed on the escalator 1, and does not need to access the inspection device 120 installed in the machine room 20. This makes it easier to rewrite the IP address of the inspection device 120 to a specific IP address.

[0077] Furthermore, in the passenger conveyor inspection system 100 of the first embodiment, the management device 110 identifies each inspection device 120 based on the operation of an operation device provided in the operation unit 10. However, this is not limited to this. For example, an operation device provided other than the operation unit 10 may be used.

[0078] Furthermore, the passenger conveyor inspection system 100 of the first embodiment has 16 inspection devices 120. However, the number is not limited to this. Any number of inspection devices 120 may be used.

[0079] Furthermore, the escalator 1 in the first embodiment may be a moving walkway. In other words, the technical concept in the first embodiment can be applied to passenger conveyors in general.
