DETAILED DESCRIPTION OF THE INVENTION

[0007] In each drawing, the dimensions of the components may be enlarged or reduced relative to the actual dimensions, for example, to facilitate understanding, and the dimensional ratios between the drawings may not be consistent. Note that in each drawing, for example, to facilitate understanding, some of the components may be omitted.

[0008] Terms including ordinal numbers such as "first" and "second" are used to describe various components, but these terms are used only to distinguish one component from another, and the components are not particularly limited by these terms. The number of components including ordinal numbers is not particularly limited, and may be, for example, one. Furthermore, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.

[0009] An embodiment of a passenger conveyor system will be described below with reference to Figures 1 to 3. Note that the following embodiment is provided as an example to aid in understanding the configuration of the passenger conveyor system, and is not intended to limit the configuration of the passenger conveyor system.

[0010] As shown in Figure 1, passenger conveyor system 20 comprises a first passenger conveyor 1a and a second passenger conveyor 1b. First passenger conveyor 1a comprises a first processing device 2a capable of communicating with monitoring device X1, and second passenger conveyor 1b comprises a second processing device 2b capable of communicating with monitoring device X1. In this specification and drawings, when there is no need to distinguish between first passenger conveyor 1a and second passenger conveyor 1b, they will simply be referred to as passenger conveyor 1, and when there is no need to distinguish between first processing device 2a and second processing device 2b, they will simply be referred to as processing device 2.

[0011] The first processing device 2a and the second processing device 2b may each be capable of communicating with the monitoring device X1 via, for example, a first communication means X2. The first communication means X2 may be, for example, a wired communication means such as a wired LAN or a communication cable, or may be, for example, a wireless communication means such as the Internet, Bluetooth, or a wireless LAN. Although not particularly limited, in this embodiment, the first communication means X2 is a wireless communication means.

[0012] The first processing device 2a and the second processing device 2b may be able to communicate with each other, for example, via a second communication means X3. The second communication means X3 may be a wired communication means such as a wired LAN or a communication cable, or may be a wireless communication means such as the Internet, Bluetooth, or a wireless LAN. Although not particularly limited, in this embodiment, the second communication means X3 is a wired communication means.

[0013] The monitoring device X1 may be installed, for example, in a building different from the building in which the passenger conveyor 1 is installed, or may be installed, for example, in the same building in which the passenger conveyor 1 is installed. Since the monitoring device X1 outputs (displays, sounds) data acquired from the processing device 2, the passenger conveyor 1 can be monitored using the monitoring device X1.

[0014] As shown in Fig. 2, the passenger conveyor 1 may include, for example, a structure 3 installed on a body, a transport unit 4 for transporting people (passengers), a pair of balustrade units 5 (only one of which is shown in Fig. 2) arranged to sandwich the transport unit 4 in the first direction D1, and a drive unit 6 for driving the transport unit 4 and the balustrade unit 5. The processing device 2 may also control the entire passenger conveyor 1, for example, as in this embodiment.

[0015] The first direction D1 is the first horizontal direction (also called the "width direction") D1, which is a direction parallel to the horizontal direction; the second direction D2 is the second horizontal direction (also called the "front-to-back direction") D2, which is a direction parallel to the horizontal direction and perpendicular to the first horizontal direction D1; and the third direction D3 is the vertical direction perpendicular to the first horizontal direction D1 and the second horizontal direction D2, which is the up-down direction D3.

[0016] The passenger conveyor 1 according to this embodiment is an escalator with stepped treads for transporting passengers, but is not limited to this configuration. For example, the passenger conveyor 1 may be a moving walkway with flat treads for transporting passengers.

[0017] The conveying unit 4 may include, for example, as in this embodiment, an endless annular running unit 4a that rotates and runs when driven by the drive unit 6, and a plurality of steps 4b that are connected to the running unit 4a and run together with the running unit 4a, and have tread surfaces for people to stand on. Although not particularly limited, the running unit 4a may be, for example, a roller chain.

[0018] Alternatively, for example, a pair of running portions 4a may be provided spaced apart in the first horizontal direction D1, and multiple steps 4b may be disposed between the pair of running portions 4a, 4a. The steps 4b may be connected to each running portion 4a so as to be rotatable about an axis in the first horizontal direction D1.

[0019] For example, as in this embodiment, the driving unit 6 may include a rotating unit 6a around which a first end of the traveling unit 4a in the second horizontal direction D2 is wound and which rotates about an axis in the first horizontal direction D1, a support unit 6b that supports a second end of the traveling unit 4a in the second horizontal direction D2, a driving source 6c that rotates the rotating unit 6a, and a braking unit 6d that brakes the driving of the driving source 6c. As a result, the step 4b is reversed by the rotating unit 6a and also by the support unit 6b.

[0020] Although not particularly limited, the rotating portion 6a may be, for example, a sprocket. Furthermore, although not particularly limited, the support portion 6b may be, for example, a guide member that guides the running portion 4a so that it rotates in the reverse direction, or may be, for example, a rotating member (e.g., a sprocket) around which the running portion 4a is wound and which rotates about an axis in the first horizontal direction D1. Furthermore, although not particularly limited, the driving source 6c may be, for example, a motor. Furthermore, although not particularly limited, the braking portion 6d may be, for example, a brake that applies braking by friction.

[0021] The balustrade section 5 may include, for example, an endless circular handrail belt 5a that rotates and runs, a balustrade main body section 5b that supports the handrail belt 5a, and a cover section 5c that covers the lower part of the balustrade main body section 5b. Note that, for example, the handrail belt 5a may run by being driven by the drive section 6, and the running of the handrail belt 5a may be synchronized with the running of the steps 4b.

[0022] The structure 3 may include, for example, machine rooms 3a and 3b arranged at each end in the second horizontal direction D2, as in this embodiment. The upper machine room 3a is referred to as the first machine room 3a, and the lower machine room 3b is referred to as the second machine room 3b. The structure 3 may also have, for example, a truss structure or a girder structure made up of multiple frame members. The processing device 2 may be arranged inside the first machine room 3a, as in this embodiment.

[0023] The passenger conveyor 1 may include, for example, a floor plate 1c attached to the structure 3 so as to cover the machine rooms 3a and 3b from above, as in this embodiment. As a result, the floor plate 1c forms boarding and disembarking sections 1d arranged at each end of the transport section 4 in the second lateral direction D2 for getting on and off the transport section 4.

[0024] 3, the passenger conveyor 1 may be equipped with, for example, an abnormality detection unit 7 that detects the occurrence of an abnormality, a power outage detection unit 8 that detects when power supply to the processing device 2 is stopped, a person detection unit 9 that detects the presence of a person in the boarding and alighting section 1d, a step speed detection unit 10 that detects the traveling speed of the step 4b, a belt speed detection unit 11 that detects the traveling speed of the handrail belt 5a, and a distance detection unit 12 that detects the traveling distance of the step 4b. The passenger conveyor 1 also has a storage battery 15 that supplies power to the processing device 2 when power supply to the processing device 2 is stopped.

[0025] The abnormality detection unit 7 is not particularly limited, but may, for example, be equipped with a sensor that detects that a foreign object has become caught between the floor plate 1c and the step 4b, or may, for example, be equipped with a sensor that detects that a foreign object has become caught between the cover portion 5c and the step 4b, or may, for example, be equipped with a sensor that detects that a foreign object has become caught in the entrance / exit of the handrail belt 5a. If the abnormality detection unit 7 detects the occurrence of an abnormality, the passenger conveyor 1 will come to an abnormal stop (the step 4b and the handrail belt 5a will stop moving).

[0026] The power outage detection unit 8 is not particularly limited, but may be, for example, an electricity meter (ammeter, voltmeter) that detects electricity (current, voltage) in the power supply line to the processing device 2, or may be, for example, an electricity meter (ammeter, voltmeter) that detects that the storage battery 15 is supplying power to the processing device 2. The person detection unit 9 is not particularly limited, but may be, for example, a sensor (e.g., a photoelectric sensor) that detects people at the boarding and disembarking area 1d.

[0027] The step speed detection unit 10 is not particularly limited, but may be, for example, a sensor (for example, a proximity sensor or an encoder) that detects the rotation of the rotating unit 6a. The belt speed detection unit 11 is not particularly limited, but may be, for example, a sensor (for example, an encoder) that detects the rotation of a belt drive wheel (not shown) that drives the handrail belt 5a. The distance detection unit 12 is not particularly limited, but may be, for example, a sensor (for example, a proximity sensor or an encoder) that detects the rotation of the rotating unit 6a.

[0028] Furthermore, the people conveyor 1 may be equipped with, for example, an input unit 13 to which various data are input, and an output unit 14 to which various data are output, as in this embodiment. Although not particularly limited, for example, the data input to the input unit 13 may be operation mode data (manual operation selection, automatic operation selection), operation instruction data (operation start instruction, operation stop instruction), step travel direction data (upper side conveyance selection, lower side conveyance selection), step travel speed data (rated speed operation selection, low speed operation selection), etc.

[0029] Furthermore, although not particularly limited, the input unit 13 may be, for example, a switch (push button switch, select switch, etc.), a touch panel, etc. Furthermore, the output unit 14 may include, for example, an external output unit 14a that outputs data to the outside (for example, the monitoring device X1, another processing device 2, etc.) as in this embodiment. Note that, although not particularly limited, the output unit 14 may also include, for example, a display unit that displays data (for example, an electronic bulletin board, a signal light), a sound generation unit that emits data as sound (for example, a buzzer, a speaker), etc.

[0030] The processing device 2 may, for example, as in this embodiment, include an acquisition unit 16 that acquires each piece of data from each unit 7 to 13, a storage unit 17 that stores each piece of data, a calculation unit 18 that calculates each piece of data, and a control unit 19 that controls each unit 6, 14. The processing device 2 may also be a computer that includes, for example, a processor such as a CPU and an MPU (for example, the calculation unit 18, the control unit 19), memories such as a ROM and a RAM (for example, the acquisition unit 16, the storage unit 17), various interfaces, etc.

[0031] As a result, the processor executes the program stored in the memory, and the software and hardware work together to realize the units 16, 17, 18, and 19 of the processing device 2. The processing device 2 may be configured, for example, with a software circuit, or may be configured, for example, with a hardware circuit, or may be configured, for example, with a combination of a software circuit and a hardware circuit.

[0032] The processing device 2 may be configured as a single device, or may be configured as a plurality of devices that can communicate with each other. Specifically, the units 16, 17, 18, and 19 of the processing device 2 may be provided in a single device, or may be distributed across a plurality of devices that can communicate with each other.

[0033] The memory unit 17 may, for example, as in this embodiment, include a self-device data memory unit 17a that stores status data indicating the status of its own passenger conveyor 1, and an other-device data memory unit 17b that stores status data acquired from other passenger conveyors 1 (specifically, the processing devices 2 of the other passenger conveyors 1). The calculation unit 18 may, for example, as in this embodiment, include a processing stop determination unit 18a that determines when processing by the processing device 2 of the other passenger conveyor 1 has stopped.

[0034] The status data stored in the own device data storage unit 17a includes major abnormality data indicating the occurrence of a major abnormality that causes the passenger conveyor 1 to stop abnormally, and minor abnormality data indicating the occurrence of a minor abnormality that allows the passenger conveyor 1 to continue operating. The status data stored in the own device data storage unit 17a may also include, for example, non-abnormality data, which is data on the passenger conveyor 1 excluding data related to abnormalities.

[0035] The serious abnormality data is not particularly limited, but may include, for example, data indicating the type of serious abnormality, data indicating the operating state (operating or stopped) when the serious abnormality occurred, data indicating the position where the serious abnormality occurred, and data indicating the time when the serious abnormality occurred. Note that the serious abnormality is not particularly limited, but may include, for example, an abnormality detected by the abnormality detection unit 7, a serious abnormality in the braking distance, a serious abnormality in the speed of the step 4b, a serious abnormality in the speed of the handrail belt 5a, etc.

[0036] The minor abnormality data is not particularly limited, but may include, for example, data indicating the type of minor abnormality, data indicating the location where the minor abnormality occurred, and data indicating the time when the minor abnormality occurred. Note that the minor abnormality is not particularly limited, but may include, for example, a minor abnormality in braking distance, a minor abnormality in the speed of the step 4b, a minor abnormality in the speed of the handrail belt 5a, and a minor abnormality in the state where the person detection unit 9 is constantly detecting a person. Note that a minor abnormality is, for example, an abnormality that does not require the operation of the people conveyor 1 to be stopped, but does require maintenance during maintenance work.

[0037] The non-abnormal data is not particularly limited, but may include, for example, operation data related to operation. Note that the operation data is not particularly limited, but may include, for example, a cumulative operation time, a number of starts, a cumulative operation distance, an elapsed time of automatic refueling, a braking distance history, etc.

[0038] The braking distance is not particularly limited, but may be calculated by the calculation unit 18 based on, for example, the timing of activation of the braking unit 6d and the detection by the distance detection unit 12. Although not particularly limited, a minor abnormality in the braking distance may be determined, for example, when the braking distance is equal to or greater than a first set distance (for example, 1.0 m) and less than a second set distance (for example, 1.2 m), or when the braking distance is equal to or less than a third set distance (for example, 0.2 m), and a major abnormality in the braking distance may be determined, for example, when the braking distance is equal to or greater than the second set distance.

[0039] The speed of step 4b is not particularly limited, and may be calculated by the calculation unit 18 based on the detection by the step speed detection unit 10. Although not particularly limited, a minor abnormality in the speed of step 4b may be determined, for example, when the speed of step 4b is equal to or greater than a first speed (for example, 110% of the rated speed) and less than a second speed (for example, 120% of the rated speed), or when the speed of step 4b is equal to or less than a third speed (for example, 90% of the rated speed), and a major abnormality in the speed of step 4b may be determined, for example, when the speed of step 4b is equal to or greater than the second speed.

[0040] The speed of the handrail belt 5a is not particularly limited, and may be calculated by the calculation unit 18 based on detection by the belt speed detection unit 11, for example. Although not particularly limited, a minor speed abnormality of the handrail belt 5a may be determined, for example, when the speed of the handrail belt 5a continues for a first time period (for example, 6 seconds) at a speed outside a first set speed range (for example, a range of 90% to 110% of the speed of step 4b), and a major speed abnormality of the handrail belt 5a may be determined, for example, when the speed of the handrail belt 5a continues for a second time period (for example, 15 seconds) at a speed outside a second set speed range (for example, a range of 85% to 115% of the speed of step 4b).

[0041] The host data storage unit 17a may store, for example, only the most recent set number (e.g., 50) of major abnormality data, or may store, for example, only the most recent major abnormality data. The host data storage unit 17a may store, for example, only the most recent set number (e.g., 50) of minor abnormality data, or may store, for example, only the currently occurring minor abnormality data.

[0042] The configuration of the passenger conveyor system 20 according to this embodiment is as described above, and next we will explain the data output method of the passenger conveyor system 20 according to this embodiment. Note that the following method is provided as an example to help understand the data output method of the passenger conveyor system 20, and is not intended to limit the data output method of the passenger conveyor system 20.

[0043] First, a data output method of the processing device 2 in normal operation will be described.

[0044] The first processing device 2a outputs at least a portion of the data stored in its own device data storage unit 17a (hereinafter also referred to as "first processed data") to the second processing device 2b. Then, the second processing device 2b acquires the first processed data and stores it in the other device data storage unit 17b.

[0045] The first processing device 2a may output the first processed data to the second processing device 2b, for example, continuously or intermittently. Note that "continuously" outputting the first processed data means, for example, that the first processing device 2a outputs the first processed data to the second processing device 2b at intervals of 1 second or less. In addition, when the output is intermittently performed, it is preferable that the first processing device 2a output the first processed data to the second processing device 2b at intervals of 30 seconds or less.

[0046] The first processing data includes at least a part of the status data stored in the device's own data storage unit 17a of the first processing device 2a. Specifically, the first processing data includes at least a part of the serious abnormality data and at least a part of the minor abnormality data stored in the device's own data storage unit 17a of the first processing device 2a.

[0047] Although not particularly limited, the first processing data may include, for example, at least a portion of the non-anomalous data stored in the local device data storage unit 17a of the first processing device 2a, and may also include, for example, clock data indicating the current time recognized by the processing device 2. Furthermore, for example, the first processing device 2a may output at least a portion of the data stored in the local device data storage unit 17a to the monitoring device X1 intermittently (for example, only once at a predetermined time each day).

[0048] The second processing device 2b also outputs at least a portion of the data stored in its own device data storage unit 17a (hereinafter also referred to as "second processed data") to the first processing device 2a. The first processing device 2a then acquires the second processed data and stores it in the other device data storage unit 17b.

[0049] The second processing device 2b may output the second processed data to the first processing device 2a, for example, continuously or intermittently. Note that "continuously" outputting the second processed data means, for example, that the second processing device 2b outputs the second processed data to the first processing device 2a at intervals of 1 second or less. In addition, when the output is intermittently performed, it is preferable that the second processing device 2b outputs the second processed data to the first processing device 2a at intervals of 30 seconds or less.

[0050] The second processing data includes at least a part of the status data stored in the device's own data storage unit 17a of the second processing device 2b. Specifically, the second processing data includes at least a part of the serious abnormality data and at least a part of the minor abnormality data stored in the device's own data storage unit 17a of the second processing device 2b.

[0051] Although not particularly limited, the second processing data may include, for example, at least a portion of the non-anomalous data stored in the device's own data storage unit 17a of the second processing device 2b, and may also include, for example, clock data indicating the current time recognized by the processing device 2. Furthermore, for example, the second processing device 2b may output at least a portion of the data stored in the device's own data storage unit 17a to the monitoring device X1 intermittently (for example, only once at a predetermined time each day).

[0052] Next, a data output method of the processing device 2 in the event of an abnormality will be described.

[0053] First, when the first processing device 2a does not acquire the second processing data from the second processing device 2b, for example, the processing stop determination unit 18a of the first processing device 2a determines that the processing of the second processing device 2b has stopped. For example, and not limited to, when the second processing device 2b is continuously outputting the second processing data to the first processing device 2a, the processing stop determination unit 18a of the first processing device 2a determines that the processing of the second processing device 2b has stopped when the second processing data is not acquired from the second processing device 2b for two seconds or more.

[0054] Then, when the processing stop determination unit 18a of the first processing device 2a determines that the processing of the second processing device 2b has stopped, the first processing device 2a outputs second processing stop data indicating that the processing of the second processing device 2b has stopped and the status data of the second man conveyor 1b stored in the other device data storage unit 17b to the monitoring device X1.

[0055] As a result, when the processing of the second processing device 2b stops, not only data indicating the stop of processing of the second processing device 2b but also data indicating the status of the second person conveyor 1b can be output to the monitoring device X1. Therefore, for example, the status of the second person conveyor 1b when the processing of the second processing device 2b stops can be grasped by the monitoring device X1.

[0056] Furthermore, for example, when the power outage detection unit 8 detects power supply to the first processing device 2a from the storage battery 15, the first processing device 2a outputs first power outage data indicating that power supply has stopped to the second processing device 2b. Thereafter, when the second processing device 2b does not acquire the first processing data from the first processing device 2a, the second processing device 2b outputs the first processing stop data and the first power outage data to the monitoring device X1.

[0057] This allows data indicating that the processing of the first processing device 2a has been stopped and data indicating that the power supply to the first processing device 2a has been stopped to be output to the monitoring device X1. Therefore, for example, the monitoring device X1 can know that the processing of the first processing device 2a has been stopped due to the power supply to the first processing device 2a being stopped.

[0058] Furthermore, when the first man conveyor 1a stops abnormally, the first processing device 2a outputs the major abnormality data (for example, data on at least the most recently occurred major abnormality) and minor abnormality data (for example, data on at least the currently occurring minor abnormality) of the first man conveyor 1a stored in its own device data storage unit 17a to the monitoring device X1. Thereafter, for example, the first processing device 2a completes the output of the major abnormality data and minor abnormality data to the monitoring device X1 by acquiring reception data indicating that it has acquired the major abnormality data and minor abnormality data from the monitoring device X1.

[0059] As a result, when the first man conveyor 1a stops abnormally, not only data indicating the details of the serious abnormality but also data indicating the details of the minor abnormality can be output to the monitoring device X1. Therefore, for example, depending on the cause of the abnormal stop of the first man conveyor 1a, the monitoring device X1 can also analyze it.

[0060] Although not particularly limited, for example, if a minor anomaly in the braking distance occurs followed by a major anomaly in the braking distance, it can be analyzed that the cause of the abnormal stop of the first passenger conveyor 1a is the braking unit 6d.Furthermore, although not particularly limited, for example, if a minor anomaly in the speed of the handrail belt 5a occurs followed by a major anomaly in the speed of the handrail belt 5a, it can be analyzed that the cause of the abnormal stop of the first passenger conveyor 1a is the belt drive device (not shown) that drives the handrail belt 5a.

[0061] For example, if the first processing device 2a does not receive the received data from the monitoring device X1, the first processing device 2a outputs proxy output data to the second processing device 2b instructing the second processing device 2b to perform proxy output. Then, if the second processing device 2b receives the proxy output data, the second processing device 2b outputs the major abnormality data and minor abnormality data of the first man conveyor 1a stored in the other device data storage unit 17b to the monitoring device X1. Thereafter, the second processing device 2b receives the received data from the monitoring device X1, thereby completing the output of the second processing device 2b to the monitoring device X1.

[0062] As a result, even if the monitoring device X1 cannot acquire data from the first processing device 2a due to a communication abnormality in the first communication means X2, the second processing device 2b outputs the major abnormality data and minor abnormality data of the first passenger conveyor 1a to the monitoring device X1. As a result, when the first passenger conveyor 1a abnormally stops, the major abnormality data and minor abnormality data of the first passenger conveyor 1a can be reliably output to the monitoring device X1.

[0063] The first processing device 2a and the second processing device 2b may perform the same output as described above, for example, as in this embodiment.

[0064] First, when the second processing device 2b does not acquire the first processing data from the first processing device 2a, the second processing device 2b outputs to the monitoring device X1 the first processing stop data indicating that the processing of the first processing device 2a has stopped and the status data of the first man conveyor 1a stored in the other device data storage unit 17b.

[0065] Furthermore, when the storage battery 15 supplies power to the second processing device 2b, the second processing device 2b outputs second power outage data indicating that the power supply has stopped to the first processing device 2a. After that, when the first processing device 2a does not acquire the second processing data from the second processing device 2b, the first processing device 2a outputs the second processing stop data and the second power outage data to the monitoring device X1.

[0066] Furthermore, if the second passenger conveyor 1b stops abnormally, the second processing device 2b outputs the major and minor abnormality data of the second passenger conveyor 1b stored in its own device data storage unit 17a to the monitoring device X1. If the second processing device 2b does not acquire received data from the monitoring device X1, the first processing device 2a outputs the major and minor abnormality data of the second passenger conveyor 2b stored in its other device data storage unit 17b to the monitoring device X1.

[0067] [1] As described above, the passenger conveyor system 20, as in this embodiment, A people conveyor system 20 comprising at least one people conveyor 1, a first processing device 2a and a second processing device 2b that are capable of communicating with the monitoring device X1; The first processing device 2a outputs first processed data to the second processing device 2b, and the second processing device 2b acquires the first processed data; The second processing device 2b outputs second processed data to the first processing device 2a, and the first processing device 2a acquires the second processed data; When the second processing device 2b does not acquire the first processing data from the first processing device 2a, the second processing device 2b outputs first processing stop data indicating that the processing of the first processing device 2a has stopped to the monitoring device X1; When the first processing device 2a does not acquire the second processing data from the second processing device 2b, the first processing device 2a outputs second processing stop data indicating that the processing of the second processing device 2b has stopped to the monitoring device X1. This configuration is preferable.

[0068] According to this configuration, when the second processing device 2b does not acquire the first processing data from the first processing device 2a, the second processing device 2b outputs the first processing stop data to the monitoring device X1. As a result, when the processing of the first processing device 2a stops, data indicating the processing stop of the first processing device 2a can be output to the monitoring device X1.

[0069] Furthermore, when the first processing device 2a does not acquire the second processing data from the second processing device 2b, the first processing device 2a outputs second processing stop data to the monitoring device X1. As a result, when the processing of the second processing device 2b stops, data indicating that the processing of the second processing device 2b has stopped can be output to the monitoring device X1.

[0070] [2] In addition, in the passenger conveyor system 20 described above in [1], as in this embodiment, The at least one passenger conveyor 1 includes a first passenger conveyor 1a and a second passenger conveyor 1b; The first processing device 2a acquires first status data indicating the status of the first man conveyor 1a, and the first processed data includes the first status data; The second processing device 2b acquires second status data indicating the status of the second man conveyor 1b, and the second processing data includes the second status data; When the first processing device 2a does not acquire the second processing data from the second processing device 2b, the first processing device 2a outputs the second processing stop data and the acquired second status data to the monitoring device X1. This configuration is preferable.

[0071] According to this configuration, when the first processing device 2a does not acquire the second processing data from the second processing device 2b, the first processing device 2a outputs the second processing stop data and the acquired second status data to the monitoring device X1. As a result, when the processing of the second processing device 2b stops, not only data indicating the processing stop of the second processing device 2b but also data indicating the status of the second man conveyor 1b can be output to the monitoring device X1.

[0072] [3] In addition, in the passenger conveyor system 20 described in [1] or [2] above, as in this embodiment, The at least one passenger conveyor 1 includes a first passenger conveyor 1a and a second passenger conveyor 1b; The first processing device 2a acquires serious abnormality data indicating the occurrence of a serious abnormality that causes the first man conveyor 1a to stop abnormally, and minor abnormality data indicating the occurrence of a minor abnormality that causes the first man conveyor 1a to continue operating, and the first processing data includes the serious abnormality data and the minor abnormality data, The second processing device 2b acquires second major abnormality data indicating the occurrence of a major abnormality that causes the second man conveyor 1b to abnormally stop, and second minor abnormality data indicating the occurrence of a minor abnormality that causes the second man conveyor 1b to continue operating, and the second processing data includes the second major abnormality data and the second minor abnormality data, When the first man conveyor 1a abnormally stops, the first processing device 2a outputs the first major abnormality data and the first minor abnormality data to the monitoring device X1. This configuration is preferable.

[0073] According to this configuration, when the first passenger conveyor 1a stops abnormally, the first processing device 2a outputs first major abnormality data and first minor abnormality data to the monitoring device X1. As a result, when the first passenger conveyor 1a stops abnormally, not only data indicating the nature of the abnormality that caused the first passenger conveyor 1a to stop abnormally, but also data indicating the nature of the abnormality that caused the first passenger conveyor 1a to continue operating can be output to the monitoring device X1.

[0074] [4] In addition, in the passenger conveyor system 20 described above in [3], as in this embodiment, After the first processing device 2a outputs the first major abnormality data and the first minor abnormality data to the monitoring device X1, if the first processing device 2a does not acquire data indicating that the first major abnormality data and the first minor abnormality data have been acquired from the monitoring device X1, the second processing device 2b outputs the first major abnormality data and the first minor abnormality data acquired from the first processing device 2a to the monitoring device X1. This configuration is preferable.

[0075] According to this configuration, when the first processing device 2a does not receive data indicating that it has received the first major abnormality data and the first minor abnormality data from the monitoring device X1, the second processing device 2b outputs the first major abnormality data and the first minor abnormality data received from the first processing device 2a to the monitoring device X1. This makes it possible to reliably output the first major abnormality data and the first minor abnormality data to the monitoring device X1 when the first man conveyor 1a abnormally stops.

[0076] [5] In addition, any one of the above-mentioned people conveyor systems 20 [1] to [4], as in this embodiment, The system further includes a storage battery 15 that supplies power to the first processing device 2a when power supply to the first processing device 2a is stopped, When power is being supplied from the storage battery 15, the first processing device 2a outputs power outage data indicating that power supply has stopped to the second processing device 2b, After acquiring the power outage data from the first processing device 2a and when not acquiring the first processing data from the first processing device 2a, the second processing device 2b outputs the first processing stop data and the power outage data to the monitoring device X1. This configuration is preferable.

[0077] According to this configuration, when the storage battery 15 is supplying power to the first processing device 2a, the first processing device 2a outputs power outage data to the second processing device 2b. If the second processing device 2b subsequently does not acquire the first processing data from the first processing device 2a, the second processing device 2b outputs the first processing stop data and power outage data to the monitoring device X1. This makes it possible to output data indicating that the first processing device 2a has stopped processing and data indicating that power supply to the first processing device 2a has stopped to the monitoring device X1.

[0078] The passenger conveyor system 20 is not limited to the configuration of the embodiment described above, nor is it limited to the effects described above. Furthermore, various modifications can be made to the passenger conveyor system 20 without departing from the spirit of the present invention. For example, it is possible to select one or more of the configurations and methods of the various modified examples described below and incorporate them into the configurations and methods of the embodiments described above.

[0079] (A) The passenger conveyor system 20 according to the above embodiment is configured to include a first passenger conveyor 1a and a second passenger conveyor 1b. In other words, the passenger conveyor system 20 is configured to include two passenger conveyors 1. However, the passenger conveyor system 20 is not limited to this configuration.

[0080] (A-1) For example, as shown in Figure 4, the number of passenger conveyors 1 provided in the passenger conveyor system 20 may be one. Then, for example, the first processing device 2a may acquire at least a portion of the status data indicating the status of the passenger conveyor 1, and the second processing device 2b may acquire at least a portion of the status data indicating the status of the passenger conveyor 1.

[0081] In the passenger conveyor system 20 shown in Figure 4, the first processing device 2a is located inside the first machine room 3a, and the second processing device 2b is located inside the second machine room 3b. However, this is not limited to such a configuration, and for example, the first processing device 2a and the second processing device 2b may be located inside the same machine room 3a (3b).

[0082] (A-2) Also, for example, the number of passenger conveyors 1 provided in passenger conveyor system 20 may be three or more. Each passenger conveyor 1 may be provided with a processing device 2, and a first processing device 2a outputs first processing data to other second to Nth processing devices 2b to 2n, and the second to Nth processing devices 2b to 2n acquire the first processing data, and if a specific processing device 2 among the second to Nth processing devices 2b to 2n does not acquire the first processing data from first processing device 2a, it may output first processing stop data indicating that processing by first processing device 2a has stopped to monitoring device X1.

[0083] (B) Furthermore, in the passenger conveyor system 20 according to the above embodiment, the processing data output from a processing device 2 to another processing device 2 includes at least status data. Specifically, the processing data output from a processing device 2 to another processing device 2 includes at least major abnormality data and minor abnormality data. However, the passenger conveyor system 20 is not limited to this configuration.

[0084] For example, the processing data output from a processing device 2 to another processing device 2 may be non-abnormal data and may not include severely abnormal data or mildly abnormal data. Also, for example, the processing data output from a processing device 2 to another processing device 2 may be data that does not include status data, such as time data, or may be simple pulse signal data.

[0085] (C) Furthermore, in the passenger conveyor system 20 according to the above embodiment, the first processing device 2a is configured to output the second processing stop data and the acquired second status data (status data of the second passenger conveyor 1b) to the monitoring device X1 when the second processing data is not acquired from the second processing device 2b. However, the passenger conveyor system 20 is not limited to this configuration. For example, the first processing device 2a may be configured to output the second processing stop data to the monitoring device X1 when the second processing data is not acquired from the second processing device 2b, but not to output the second status data to the monitoring device X1.

[0086] (D) Furthermore, in the passenger conveyor system 20 according to the above embodiment, the second processing device 2b is configured to output the first processing stop data and the acquired first status data (status data of the first passenger conveyor 1a) to the monitoring device X1 when the second processing device 2b does not acquire the first processing data from the first processing device 2a. However, the passenger conveyor system 20 is not limited to this configuration. For example, the second processing device 2b may be configured to output the first processing stop data to the monitoring device X1 when the second processing device 2b does not acquire the first processing data from the first processing device 2a, but not to output the first status data to the monitoring device X1.

[0087] (E) Furthermore, in the passenger conveyor system 20 according to the above embodiment, the first processing device 2a is configured to output first major abnormality data and first minor abnormality data (major abnormality data and minor abnormality data of the first passenger conveyor 1a) to the monitoring device X1 when the first passenger conveyor 1a abnormally stops. However, the passenger conveyor system 20 is not limited to this configuration.

[0088] For example, the first processing device 2a may be configured not to output any data to the monitoring device X1 when the first passenger conveyor 1a abnormally stops. Alternatively, for example, the first processing device 2a may be configured to output first major abnormality data to the monitoring device X1 when the first passenger conveyor 1a abnormally stops, but not to output first minor abnormality data to the monitoring device X1. Alternatively, for example, the first processing device 2a may be configured to output abnormal stop data indicating only that the first passenger conveyor 1a has abnormally stopped to the monitoring device X1, but not to output the first major abnormality data or the first minor abnormality data to the monitoring device X1 when the first passenger conveyor 1a abnormally stops.

[0089] (F) Furthermore, in the passenger conveyor system 20 according to the above embodiment, the second processing device 2b is configured to output second major abnormality data and second minor abnormality data (major abnormality data and minor abnormality data of the second passenger conveyor 1b) to the monitoring device X1 when the second passenger conveyor 1b abnormally stops. However, the passenger conveyor system 20 is not limited to this configuration.

[0090] For example, the second processing device 2b may be configured not to output any data to the monitoring device X1 when the second passenger conveyor 1b abnormally stops. Alternatively, for example, the second processing device 2b may be configured to output second major abnormality data to the monitoring device X1 when the second passenger conveyor 1b abnormally stops, but not to output second minor abnormality data to the monitoring device X1. Alternatively, for example, the second processing device 2b may be configured to output abnormal stop data indicating only that the second passenger conveyor 1b has abnormally stopped to the monitoring device X1, but not to output the second major abnormality data or the second minor abnormality data to the monitoring device X1 when the second passenger conveyor 1b abnormally stops.

[0091] (G) Furthermore, in the passenger conveyor system 20 according to the above embodiment, if the first processing device 2a does not receive receipt data indicating that it has received the first major abnormality data and the first minor abnormality data (the major abnormality data and the minor abnormality data of the first passenger conveyor 1a) from the monitoring device X1, the second processing device 2b outputs the first major abnormality data and the first minor abnormality data received from the first processing device 2a to the monitoring device X1. However, the passenger conveyor system 20 is not limited to this configuration.

[0092] For example, when the first processing device 2a does not acquire receipt data indicating that it has acquired the first major abnormality data and the first minor abnormality data from the monitoring device X1, the second processing device 2b may be configured, for example, to not output any data to the monitoring device X1, or may be configured, for example, to output the first major abnormality data to the monitoring device X1 but not output the first minor abnormality data to the monitoring device X1, or may be configured, for example, to output abnormal stop data indicating only that the first man conveyor 1a has abnormally stopped to the monitoring device X1 but not output the first major abnormality data and the first minor abnormality data to the monitoring device X1.

[0093] (H) Furthermore, in the passenger conveyor system 20 according to the above embodiment, when the second processing device 2b does not receive receipt data indicating that it has received the second major abnormality data and second minor abnormality data (the major abnormality data and minor abnormality data of the second passenger conveyor 1b) from the monitoring device X1, the second processing device 2b outputs the first major abnormality data and first minor abnormality data received from the first processing device 2a to the monitoring device X1. However, the passenger conveyor system 20 is not limited to this configuration.

[0094] For example, when the second processing device 2b does not acquire receipt data indicating that it has acquired the second major abnormality data and the second minor abnormality data from the monitoring device X1, the first processing device 2a may be configured, for example, to not output any data to the monitoring device X1, or may be configured, for example, to output the second major abnormality data to the monitoring device X1 but not output the second minor abnormality data to the monitoring device X1, or may be configured, for example, to output abnormal stop data indicating only that the second man conveyor 2b has abnormally stopped to the monitoring device X1 but not output the second major abnormality data and the second minor abnormality data to the monitoring device X1.

[0095] (I) Furthermore, in the passenger conveyor system 20 according to the above embodiment, the passenger conveyor 1 is configured to include a storage battery 15 that supplies power to the processing device 2 when power supply to the processing device 2 is stopped. However, the passenger conveyor system 20 is not limited to this configuration.

[0096] For example, the first man conveyor 1a may be configured not to have a storage battery 15 that supplies power to the first processing device 2a when power supply to the first processing device 2a is stopped. Also, for example, the second man conveyor 1b may be configured not to have a storage battery 15 that supplies power to the second processing device 2b when power supply to the second processing device 2b is stopped.

[0097] (J) Furthermore, in the passenger conveyor system 20 according to the above embodiment, the first processing device 2a is configured to output power outage data indicating that the power supply has stopped to the second processing device 2b when power is being supplied from the storage battery 15. However, the passenger conveyor system 20 is not limited to this configuration.

[0098] For example, the first processing device 2a may be configured to output power outage data to the monitoring device X1, rather than to the second processing device 2b (or not only to the second processing device 2b), when power is being supplied from the storage battery 15. Furthermore, for example, the first processing device 2a may be configured not to output power outage data to the second processing device 2b or the monitoring device X1, when power is being supplied from the storage battery 15.

[0099] (K) Furthermore, in the passenger conveyor system 20 according to the above embodiment, the second processing device 2b is configured to output power outage data indicating that the power supply has stopped to the first processing device 2a when power is being supplied from the storage battery 15. However, the passenger conveyor system 20 is not limited to this configuration.

[0100] For example, the second processing device 2b may be configured to output power outage data to the monitoring device X1, rather than to the first processing device 2a (or not only to the first processing device 2a), when power is being supplied from the storage battery 15. Furthermore, for example, the second processing device 2b may be configured not to output power outage data to the first processing device 2a or the monitoring device X1, when power is being supplied from the storage battery 15.

[0101] (L) Furthermore, in the passenger conveyor system 20 according to the above embodiment, the second processing device 2b is configured to output the first processing stop data and the power outage data to the monitoring device X1 if the second processing device 2b does not acquire the first processing data from the first processing device 2a after acquiring the power outage data from the first processing device 2a. However, the passenger conveyor system 20 is not limited to this configuration. For example, the second processing device 2b may be configured to output the first processing stop data to the monitoring device X1 but not output the power outage data to the monitoring device X1 if the second processing device 2b does not acquire the first processing data from the first processing device 2a after acquiring the power outage data from the first processing device 2a.

[0102] (M) Furthermore, in the passenger conveyor system 20 according to the above embodiment, the first processing device 2a is configured to output the second processing stop data and the power outage data to the monitoring device X1 when it does not acquire the second processing data from the second processing device 2b after acquiring the power outage data from the second processing device 2b. However, the passenger conveyor system 20 is not limited to this configuration. For example, the first processing device 2a may be configured to output the second processing stop data to the monitoring device X1 but not output the power outage data to the monitoring device X1 when it does not acquire the second processing data from the second processing device 2b after acquiring the power outage data from the second processing device 2b.

[0103] (N) It ​​should be noted that, for example, the order of execution of each process, such as operations, procedures, steps, and stages, in the systems, methods, programs, and devices shown in the claims, specifications, and drawings, can be realized in any order, as long as the output of a previous process is not used in a subsequent process. For example, even if a description is made using "first," "next," etc. for convenience, this does not mean that the processes must be executed in that order. [Explanation of symbols]
