Modes for Carrying Out the Invention

[0007] In each drawing, the dimensions of the components may be enlarged or reduced with respect to the actual dimensions for ease of understanding, for example, and the dimensional ratios between the drawings may not match. Note that in each drawing, a part of the components may be omitted for ease of understanding, for example.

[0008] Terms including ordinals such as first and second are used to describe various components, but this term is used only for the purpose of distinguishing one component from another, and the components are not particularly limited by this term. Note that the number of components including ordinals is not particularly limited, and may be, for example, one. Also, the ordinals used in the following specification and drawings may be different from the ordinals described in the claims.

[0009] Hereinafter, an embodiment of the diaper conveyor system will be described with reference to FIGS. 1 to 3. The following embodiments are exemplified to assist in understanding the configuration of the diaper conveyor system and do not limit the configuration of the diaper conveyor system.

[0010] As shown in FIG. 1, the diaper conveyor system 20 includes a first diaper conveyor 1a and a second diaper conveyor 1b. The first diaper conveyor 1a includes a first processing device 2a that can communicate with the monitoring device X1, and the second diaper conveyor 1b includes a second processing device 2b that can communicate with the monitoring device X1. In this specification and the drawings, when the first diaper conveyor 1a and the second diaper conveyor 1b are not distinguished, they are simply referred to as the diaper conveyor 1, and when the first processing device 2a and the second processing device 2b are not distinguished, they are simply referred to as the processing device 2.

[0011] The first processing device 2a and the second processing device 2b may be able to communicate with the monitoring device X1 respectively, for example, by the 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 (Registered Trademark) , or a wireless LAN. Although not particularly limited, in this embodiment, the first communication means X2 is a wireless communication means.

[0012] In addition, the first processing device 2a and the second processing device 2b may be able to communicate with each other, for example, by the second communication means X3. The second communication means X3 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 second communication means X3 is a wired communication means.

[0013] Note that the monitoring device X1 may be installed in a building different from the building where the man conveyor 1 is installed, or may be installed in the same building as the building where the man conveyor 1 is installed. And since the monitoring device X1 outputs (displays, emits sound) the data acquired from the processing device 2, the man conveyor 1 can be monitored using the monitoring device X1.

[0014] As shown in FIG. 2, the man conveyor 1 may include, for example, a structure 3 installed on the body, a conveying unit 4 for conveying a person (passenger), a pair of railing units 5 (only one is shown in FIG. 2) arranged so as to sandwich the conveying unit 4 in the first direction D1, and a driving unit 6 for driving the conveying unit 4 and the railing units 5. And the processing device 2 may control the entire man conveyor 1, for example, as in the present embodiment.

[0015] The first direction D1 is a first lateral direction (also referred to as "width direction") D1 that is parallel to the horizontal direction, the second direction D2 is a direction parallel to the horizontal direction and orthogonal to the first lateral direction D1, and is a second lateral direction (also referred to as "front-rear direction") D2, and the third direction D3 is a vertical direction orthogonal to the first lateral direction D1 and the second lateral direction D2, and is an up-down direction D3.

[0016] The man conveyor 1 according to the present embodiment is an escalator having a stepped tread surface for conveying a person, but is not limited to such a configuration. For example, the man conveyor 1 may be a moving walkway (moving sidewalk) having a flat tread surface for conveying a person.

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

[0018] Further, for example, a pair of traveling units 4a may be provided apart from each other in a first lateral direction D1, and a plurality of steps 4b may be arranged between the pair of traveling units 4a, 4a. And each step 4b may be rotatably connected to each traveling unit 4a about the first lateral direction D1 as an axis.

[0019] The drive unit 6 may include, for example, as in this embodiment, a rotating part 6a around which a first end portion in a second lateral direction D2 of the traveling unit 4a is wound and which rotates about the first lateral direction D1, a support part 6b that supports a second end portion in the second lateral direction D2 of the traveling unit 4a, a drive source 6c that rotates the rotating part 6a, and a braking part 6d that brakes the drive of the drive source 6c. Thereby, the step 4b is inverted by the rotating part 6a and is also inverted by the support part 6b.

[0020] Although not particularly limited, the rotating part 6a may be, for example, a sprocket. Also, although not particularly limited, the support part 6b may be, for example, a guide material that guides the traveling unit 4a to invert, or may be, for example, a rotating member (for example, a sprocket) around which the traveling unit 4a is wound and that rotates about the first lateral direction D1. Also, although not particularly limited, the drive source 6c may be, for example, a motor. Also, although not particularly limited, the braking part 6d may be, for example, a brake that brakes by friction.

[0021] The railing part 5 may include, for example, an endless annular handrail belt 5a that rotates and travels, a railing main body part 5b that supports the handrail belt 5a, and a cover part 5c that covers the lower part of the railing main body part 5b. Note that, for example, the handrail belt 5a travels by the drive of the drive unit 6, and the travel of the handrail belt 5a may be synchronized with the travel of the step 4b.

[0022] The structure 3 may include machine rooms 3a and 3b disposed at respective ends in the second lateral direction D2, for example, as in this embodiment. Note that the machine room 3a disposed above is referred to as the first machine room 3a, and the machine room 3b disposed below is referred to as the second machine room 3b. Further, the structure 3 may be, for example, a truss structure or a lattice structure composed of a plurality of frame members. Note that the processing device 2 may be disposed inside the first machine room 3a, for example, as in this embodiment.

[0023] The man conveyor 1 may include a floor plate 1c attached to the structure 3 so as to cover the machine rooms 3a and 3b from above, for example, as in this embodiment. Thereby, the floor plate 1c constitutes boarding and alighting portions 1d disposed at respective ends in the second lateral direction D2 of the conveying unit 4 for boarding and alighting from the conveying unit 4.

[0024] As shown in FIG. 3, the man conveyor 1 may include, for example, an abnormality detection unit 7 that detects the occurrence of an abnormality, a power failure detection unit 8 that detects the stoppage of power supply to the processing device 2, a person detection unit 9 that detects the presence of a person in the boarding and alighting portion 1d, a step speed detection unit 10 that detects the traveling speed in 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 in step 4b. Further, the man conveyor 1 includes a storage battery 15 that supplies power to the processing device 2 when the power supply to the processing device 2 stops.

[0025] The abnormality detection unit 7 is not particularly limited, but may include, for example, a sensor that detects that a foreign object is caught between the floor plate 1c and the step 4b, or may include, for example, a sensor that detects that a foreign object is caught between the cover portion 5c and the step 4b, or may include, for example, a sensor that detects that a foreign object is caught at the entrance and exit of the handrail belt 5a. When the abnormality detection unit 7 detects the occurrence of an abnormality, the man conveyor 1 stops abnormally (stops the traveling of the step 4b and the handrail belt 5a).

[0026] The power outage detection unit 8 is not particularly limited, and for example, it may be an ammeter (ammeter, voltmeter) that detects the electricity (current, voltage) of the power supply path to the processing device 2. Also, for example, it may be an ammeter (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, and for example, it may be a sensor (e.g., a photoelectric sensor) that detects a person at the boarding and alighting section 1d.

[0027] The step speed detection unit 10 is not particularly limited, and for example, it may be a sensor (e.g., a proximity sensor, an encoder) that detects the rotation of the rotating part 6a. The belt speed detection unit 11 is not particularly limited, and for example, it may be a sensor (e.g., 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, and for example, it may be a sensor (e.g., a proximity sensor, an encoder) that detects the rotation of the rotating part 6a.

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

[0029] Also, although not particularly limited, the input unit 13 may be, for example, a switch (push button switch, select switch, etc.), a touch panel, etc. Also, the output unit 14 may include, for example, an external output unit 14a that outputs data to the outside (e.g., a 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 (e.g., an electric bulletin board, an indicator light), a sound emitting unit that emits data as sound (e.g., a buzzer, a speaker), etc.

[0030] The processing device 2 may include, for example, as in this embodiment, an acquisition unit 16 that acquires each data from each of the units 7 to 13, a storage unit 17 that stores each data, an arithmetic unit 18 that performs arithmetic operations on each data, and a control unit 19 that controls each of the units 6 and 14. And the processing device 2 may be, for example, a computer including a processor such as a CPU and an MPU (for example, the arithmetic unit 18 and the control unit 19), a memory such as a ROM and a RAM (for example, the acquisition unit 16 and the storage unit 17), and various interfaces and the like.

[0031] Thereby, the processor executes the program stored in the memory, and by the cooperation of software and hardware, each of the units 16, 17, 18, and 19 of the processing device 2 is realized. Note that the processing device 2 may be configured by, for example, a soft circuit, or may be configured by, for example, a hard circuit, or may be configured by, for example, a combination of a soft circuit and a hard circuit.

[0032] Also, the processing device 2 may be configured by, for example, a single device, or may be configured by, for example, a plurality of devices capable of communicating with each other. Specifically, each of the units 16, 17, 18, and 19 of the processing device 2 may be provided in, for example, a single device, or may be distributed and provided in a plurality of devices capable of communicating with each other.

[0033] The storage unit 17 may include, for example, as in this embodiment, a self-device data storage unit 17a that stores state data indicating the state of its own man conveyor 1, and an other-device data storage unit 17b that stores state data acquired from another man conveyor 1 (specifically, the processing device 2 of another man conveyor 1). The arithmetic unit 18 may include, for example, as in this embodiment, a processing stop determination unit 18a that determines that the processing of the processing device 2 of another man conveyor 1 has stopped.

[0034] Incidentally, the state data stored in the own device data storage unit 17a includes heavy abnormality data indicating the content of a serious abnormality that caused the man conveyor 1 to stop abnormally, and light abnormality data indicating the content of a minor abnormality that allowed the operation of the man conveyor 1 to continue. Further, the state data stored in the own device data storage unit 17a may include normal data, which is, for example, data of the man conveyor 1 excluding data related to abnormalities.

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

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

[0037] The normal data is not particularly limited. For example, it may include operation data related to operation. Note that the operation data is not particularly limited. For example, it may include the cumulative operation time, the number of startups, the cumulative operation distance, the elapsed time of automatic fuel supply, the history of the braking distance, and the like.

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

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

[0040] The speed of the handrail belt 5a is not particularly limited. For example, it may be calculated by the calculation unit 18 based on the detection by the belt speed detection unit 11. Although not particularly limited, a slight abnormality in the speed of the handrail belt 5a may be, for example, when the speed of the handrail belt 5a is outside the first set speed range (e.g., in the range of 90% - 110% of the speed in step 4b) and continues for a first time (e.g., 6 seconds). Also, a serious abnormality in the speed of the handrail belt 5a may be, for example, when the speed of the handrail belt 5a is outside the second set speed range (in the range of 85% - 115% of the speed in step 4b) and continues for a second time (e.g., 15 seconds).

[0041] Note that the self-device data storage unit 17a may store, for example, only the latest set number (e.g., 50) of heavy abnormality data, or may store only the latest heavy abnormality data. Also, the self-device data storage unit 17a may store, for example, only the latest set number (e.g., 50) of light abnormality data, or may store only the currently occurring light abnormality data.

[0042] The configuration of the man conveyor system 20 according to this embodiment is as described above. Next, a data output method of the man conveyor system 20 according to this embodiment will be described. Note that the following method is an example for assisting in understanding the data output method and the like of the man conveyor system 20, and does not limit the data output method of the man conveyor system 20.

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

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

[0045] The first processing device 2a outputting the first processing data to the second processing device 2b may be executed continuously, for example, or may be executed intermittently, for example. Note that the output being "executed continuously" means, for example, that the interval at which the first processing device 2a outputs the first processing data to the second processing device 2b is 1 second or less. Also, when the output is executed intermittently, for example, it is preferable that the interval at which the first processing device 2a outputs the first processing data to the second processing device 2b is 30 seconds or less.

[0046] The first processing data includes at least a part of the state data stored in the own-device data storage unit 17a of the first processing device 2a. Specifically, the first processing data includes at least a part of the severe abnormality data and at least a part of the minor abnormality data stored in the own-device 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 part of the non-abnormality data stored in the own-device data storage unit 17a of the first processing device 2a, and may also include, for example, the clock data indicating the current time recognized by the processing device 2. Further, for example, the first processing device 2a may intermittently output (for example, only once at a preset time of a day) at least a part of the data stored in the own-device data storage unit 17a to the monitoring device X1.

[0048] Also, the second processing device 2b outputs at least a part of the data (hereinafter, also referred to as "second processing data") stored in the own-device data storage unit 17a to the first processing device 2a. Then, the first processing device 2a acquires the second processing data and stores the second processing data in the other-device data storage unit 17b.

[0049] The output of the second processing data from the second processing device 2b to the first processing device 2a may be executed continuously, for example, or may be executed intermittently, for example. Note that the "continuously executed" output means, for example, that the interval at which the second processing device 2b outputs the second processing data to the first processing device 2a is 1 second or less. Also, when the output is executed intermittently, for example, it is preferable that the interval at which the second processing device 2b outputs the second processing data to the first processing device 2a is 30 seconds or less.

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

[0051] Note that, although not particularly limited, the second processing data may include, for example, at least a part of the normal data stored in the own device 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. Further, for example, the second processing device 2b may intermittently output (for example, only once at a predetermined time of a day) at least a part of the data stored in the own device data storage unit 17a to the monitoring device X1.

[0052] Next, a data output method of the processing device 2 in the case 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. Although not particularly limited, for example, when the second processing device 2b continuously outputs 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 it does not acquire the second processing data from the second processing device 2b for 2 seconds or more.

[0054] And 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 to the monitoring device X1 the second processing stop data indicating that the processing of the second processing device 2b has stopped and the state data of the second man conveyor 1b stored in the other device data storage unit 17b.

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

[0056] Also, for example, when the power outage detection unit 8 detects power supply from the storage battery 15 to the first processing device 2a, the first processing device 2a outputs first power outage data indicating that the power supply has stopped to the second processing device 2b. Thereafter, when the second processing device 2b fails to 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] Thereby, data indicating the stop of the processing of the first processing device 2a and data indicating the stop of the power supply to the first processing device 2a can be output to the monitoring device X1. Therefore, for example, it is possible for the monitoring device X1 to recognize that the processing of the first processing device 2a has stopped due to the stop of the power supply to the first processing device 2a.

[0058] Also, when the first man conveyor 1a stops abnormally, the first processing device 2a outputs heavy abnormality data (for example, at least the data of the latest heavy abnormality) and light abnormality data (for example, at least the data of the currently occurring light abnormality) of the first man conveyor 1a stored in its own device data storage unit 17a to the monitoring device X1. Thereafter, for example, when the first processing device 2a acquires reception data indicating that it has acquired the heavy abnormality data and the light abnormality data from the monitoring device X1, the output of the first processing device 2a to the monitoring device X1 is completed.

[0059] Thereby, when the first man conveyor 1a stops abnormally, not only data indicating the content of the heavy abnormality but also data indicating the content of the light 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, it can also be analyzed by the monitoring device X1.

[0060] Although not particularly limited, for example, when a serious abnormality in the braking distance occurs after a slight abnormality in the braking distance, if the cause of the abnormal stop of the first manual conveyor 1a is the braking unit 6d, it can be analyzed. Also, although not particularly limited, for example, when a serious abnormality in the speed of the handrail belt 5a occurs after a slight abnormality in the speed of the handrail belt 5a, if the cause of the abnormal stop of the first manual conveyor 1a is a belt drive device (not shown) that drives the handrail belt 5a, it can be analyzed.

[0061] In addition, for example, when the first processing device 2a does not acquire the received data from the monitoring device X1, the first processing device 2a outputs proxy output data instructing proxy output to the second processing device 2b. And when the second processing device 2b acquires the proxy output data, the second processing device 2b outputs the serious abnormality data and the slight abnormality data of the first manual conveyor 1a stored in the other device data storage unit 17b to the monitoring device X1. After that, when the second processing device 2b acquires the received data from the monitoring device X1, the output of the second processing device 2b to the monitoring device X1 is completed.

[0062] Thereby, for example, even when the monitoring device X1 cannot acquire data from the first processing device 2a due to a communication abnormality of the first communication means X2, the second processing device 2b outputs the serious abnormality data and the slight abnormality data of the first manual conveyor 1a to the monitoring device X1. Thereby, when the first manual conveyor 1a stops abnormally, the serious abnormality data and the slight abnormality data of the first manual conveyor 1a can be surely output to the monitoring device X1.

[0063] Note that the first processing device 2a and the second processing device 2b may execute 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 the first processing stop data indicating that the processing of the first processing device 2a has stopped and the state data of the first manual conveyor 1a stored in the other device data storage unit 17b to the monitoring device X1.

[0065] Also, when the storage battery 15 supplies power to the second processing device 2b, the second processing device 2b outputs second power failure data indicating that the power supply has stopped to the first processing device 2a. Thereafter, 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 failure data to the monitoring device X1.

[0066] Also, when the second man conveyor 1b stops abnormally, the second processing device 2b outputs the heavy abnormality data and the light abnormality data of the second man conveyor 1b stored in the own device data storage unit 17a to the monitoring device X1. And when the second processing device 2b does not acquire the received data from the monitoring device X1, the first processing device 2a outputs the heavy abnormality data and the light abnormality data of the second man conveyor 2b stored in the other device data storage unit 17b to the monitoring device X1.

[0068] According to such a 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. Thereby, when the processing of the first processing device 2a stops, data indicating the stop of the processing of the first processing device 2a can be output to the monitoring device X1.

[0069] Also, 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 to the monitoring device X1. Thereby, when the processing of the second processing device 2b stops, data indicating the stop of the processing of the second processing device 2b can be output to the monitoring device X1.

[0070] [2] Also, in the man conveyor system 20 of the above [1], as in the present embodiment, the at least one man conveyor 1 includes a first man conveyor 1a and a second man conveyor 1b, the first processing device 2a acquires first state data indicating the state of the first man conveyor 1a, and the first processing data includes the first state data, the second processing device 2b acquires second state data indicating the state of the second man conveyor 1b, and the second processing data includes the second state 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 state data to the monitoring device X1, such a configuration is preferable.

[0071] According to such a 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 state data to the monitoring device X1. Thereby, when the processing of the second processing device 2b stops, not only data indicating the stop of the processing of the second processing device 2b but also data indicating the state of the second man conveyor 1b can be output to the monitoring device X1.

[0072] [3] Also, in the man conveyor system 20 of the above [1] or [2], as in the present embodiment, the at least one man conveyor 1 includes a first man conveyor 1a and a second man conveyor 1b, the first processing device 2a acquires heavy abnormality data indicating the content of a heavy abnormality that has occurred and caused the first man conveyor 1a to stop abnormally, and light abnormality data indicating the content of a light abnormality that has occurred and allowed the operation of the first man conveyor 1a to continue, and the first processing data includes the heavy abnormality data and the light abnormality data, the second processing device 2b acquires second heavy abnormality data indicating the content of a heavy abnormality that has occurred and caused the second man conveyor 1b to stop abnormally, and second light abnormality data indicating the content of a light abnormality that has occurred and allowed the operation of the second man conveyor 1b to continue, and the second processing data includes the second heavy abnormality data and the second light abnormality data, when the first man conveyor 1a stops abnormally, the first processing device 2a outputs the first heavy abnormality data and the first light abnormality data to the monitoring device X1, such a configuration is preferable.

[0073] According to such a configuration, when the first man conveyor 1a stops abnormally, the first processing device 2a outputs the first heavy abnormality data and the first light abnormality data to the monitoring device X1. Thereby, when the first man conveyor 1a stops abnormally, not only the data indicating the content of the abnormality that has caused the first man conveyor 1a to stop abnormally, but also the data indicating the content of the abnormality that has allowed the operation of the first man conveyor 1a to continue can be output to the monitoring device X1.

[0074] [4] Also, in the man conveyor system 20 of the above [3], as in the present embodiment, After the first processing device 2a outputs the first serious abnormality data and the first minor abnormality data to the monitoring device X1, when the first processing device 2a does not acquire data indicating that it has acquired the first serious abnormality data and the first minor abnormality data from the monitoring device X1, the second processing device 2b outputs the first serious abnormality data and the first minor abnormality data acquired from the first processing device 2a to the monitoring device X1. Such a configuration is preferable.

[0075] According to such a configuration, when the first processing device 2a does not acquire data indicating that it has acquired the first serious abnormality data and the first minor abnormality data from the monitoring device X1, the second processing device 2b outputs the first serious abnormality data and the first minor abnormality data acquired from the first processing device 2a to the monitoring device X1. Thereby, when the first man conveyor 1a abnormally stops, the first serious abnormality data and the first minor abnormality data can be surely output to the monitoring device X1.

[0076] [5] Moreover, any one of the man conveyor systems 20 of the above [1] to [4], like this embodiment, further includes a storage battery 15 that supplies power to the first processing device 2a when power supply to the first processing device 2a stops, when the first processing device 2a is being powered by the storage battery 15, the first processing device 2a outputs power failure data indicating that power supply has stopped to the second processing device 2b, after the second processing device 2b acquires the power failure data from the first processing device 2a and 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 power failure data to the monitoring device X1. Such a configuration is preferable.

[0077] According to such a configuration, when the storage battery 15 supplies power to the first processing device 2a, the first processing device 2a outputs power failure data to the second processing device 2b. After that, when the second processing device 2b fails to acquire the first processing data from the first processing device 2a, the second processing device 2b outputs the first processing stop data and the power failure data to the monitoring device X1. Thereby, it is possible to output to the monitoring device X1 the data indicating the stop of the processing of the first processing device 2a and the data indicating the stop of power supply to the first processing device 2a.

[0078] Note that the man conveyor system 20 is not limited to the configuration of the above-described embodiment, nor is it limited to the above-described effects. Further, the man conveyor system 20 can of course be variously modified without departing from the gist of the present invention. For example, it is of course possible to arbitrarily select one or more of the configurations and methods according to the following various modification examples and adopt them in the configurations and methods according to the above-described embodiment.

[0079] (A) The man conveyor system 20 according to the above-described embodiment has a configuration in which it includes the first man conveyor 1a and the second man conveyor 1b. That is, the number of man conveyors 1 included in the man conveyor system 20 is two. However, the man conveyor system 20 is not limited to such a configuration.

[0080] (A-1) For example, as shown in FIG. 4, the number of man conveyors 1 included in the man conveyor system 20 may be one. And, for example, the first processing device 2a may acquire at least a part of the state data indicating the state of the man conveyor 1, and the second processing device 2b may acquire at least a part of the state data indicating the state of the man conveyor 1.

[0081] In the man conveyor system 20 according to FIG. 4, the first processing device 2a is disposed inside the first machine room 3a, and the second processing device 2b is disposed inside the second machine room 3b. Note that the present invention is not limited to such a configuration. For example, the first processing device 2a and the second processing device 2b may be disposed inside the same machine room 3a (3b).

[0082] (A-2) Further, for example, the man conveyor system 20 may be configured such that the number of man conveyors 1 included is three or more. And, for example, each of the man conveyors 1 includes a processing device 2. The first processing device 2a outputs first processing data to the other second to Nth processing devices 2b to 2n. The second to Nth processing devices 2b to 2n acquire the first processing data. Among the second to Nth processing devices 2b to 2n, when a specific processing device 2 does not acquire the first processing data from the first processing device 2a, the specific processing device 2 outputs first processing stop data indicating that the processing of the first processing device 2a has stopped, to the monitoring device X1. Such a configuration may be employed.

[0083] (B) Further, in the man conveyor system 20 according to the above embodiment, the processing data output from the processing device 2 to another processing device 2 includes at least status data. Specifically, the processing data output from the processing device 2 to another processing device 2 includes at least heavy abnormality data and light abnormality data. However, the man conveyor system 20 is not limited to such a configuration.

[0084] For example, the processing data output from the processing device 2 to another processing device 2 may be normal data and may not include heavy abnormality data and light abnormality data. Further, for example, the processing data output from the processing device 2 to another processing device 2 may be data that does not include status data, for example, time data. Further, for example, the processing data may be merely data of a pulse signal.

[0085] (C) Also, in the diaper conveyor system 20 according to the above embodiment, 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 state data (the state data of the second diaper conveyor 1b) to the monitoring device X1. However, the diaper conveyor system 20 is not limited to such a configuration. For example, when the first processing device 2a does not acquire the second processing data from the second processing device 2b, the first processing device 2a may be configured to output the second processing stop data to the monitoring device X1 and not output the second state data to the monitoring device X1.

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

[0087] (E) Also, in the diaper conveyor system 20 according to the above embodiment, when the first diaper conveyor 1a stops abnormally, the first processing device 2a outputs the first serious abnormality data and the first minor abnormality data (the serious abnormality data and the minor abnormality data of the first diaper conveyor 1a) to the monitoring device X1. However, the diaper conveyor system 20 is not limited to such a configuration.

[0088] For example, the first processing device 2a may be configured not to output any data, particularly, to the monitoring device X1 when the first man conveyor 1a stops abnormally. Also, for example, the first processing device 2a may be configured to output first severe abnormality data to the monitoring device X1 and not output first mild abnormality data to the monitoring device X1 when the first man conveyor 1a stops abnormally. Further, for example, the first processing device 2a may be configured to output abnormality stop data indicating only that the first man conveyor 1a has stopped abnormally to the monitoring device X1 and not output the first severe abnormality data and the first mild abnormality data to the monitoring device X1 when the first man conveyor 1a stops abnormally.

[0089] (F) Also, in the man conveyor system 20 according to the above embodiment, when the second man conveyor 1b stops abnormally, the second processing device 2b is configured to output second severe abnormality data and second mild abnormality data (severe abnormality data and mild abnormality data of the second man conveyor 1b) to the monitoring device X1. However, the man conveyor system 20 is not limited to such a configuration.

[0090] For example, the second processing device 2b may be configured not to output any data, particularly, to the monitoring device X1 when the second man conveyor 1b stops abnormally. Also, for example, the second processing device 2b may be configured to output second severe abnormality data to the monitoring device X1 and not output second mild abnormality data to the monitoring device X1 when the second man conveyor 1b stops abnormally. Further, for example, the second processing device 2b may be configured to output abnormality stop data indicating only that the second man conveyor 1b has stopped abnormally to the monitoring device X1 and not output the second severe abnormality data and the second mild abnormality data to the monitoring device X1 when the second man conveyor 1b stops abnormally.

[0091] (G) Also, in the man conveyor system 20 according to the above embodiment, when the first processing device 2a does not acquire reception data indicating that it has acquired the first serious abnormality data and the first minor abnormality data (the serious abnormality data and the minor abnormality data of the first man conveyor 1a) from the monitoring device X1, the second processing device 2b outputs the first serious abnormality data and the first minor abnormality data acquired from the first processing device 2a to the monitoring device X1. However, the man conveyor system 20 is not limited to such a configuration.

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

[0093] (H) Also, in the man conveyor system 20 according to the above embodiment, when the second processing device 2b does not acquire reception data indicating that it has acquired the second serious abnormality data and the second minor abnormality data (the serious abnormality data and the minor abnormality data of the second man conveyor 1b) from the monitoring device X1, the second processing device 2b outputs the first serious abnormality data and the first minor abnormality data acquired from the first processing device 2a to the monitoring device X1. However, the man conveyor system 20 is not limited to such a configuration.

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

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

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

[0097] (J) Further, in the man conveyor system 20 according to the above embodiment, the first processing device 2a is configured to output power failure data indicating that the power supply has stopped to the second processing device 2b when being powered by the storage battery 15. However, the man conveyor system 20 is not limited to such a configuration.

[0098] For example, the first processing device 2a may be configured to output power failure data to the monitoring device X1 instead of (or not only to) the second processing device 2b when being powered by the storage battery 15. Further, for example, the first processing device 2a may be configured not to output power failure data to the second processing device 2b and the monitoring device X1 when being powered by the storage battery 15.

[0099] (K) Further, in the man conveyor system 20 according to the above embodiment, when the second processing device 2b is powered by the storage battery 15, the second processing device 2b outputs power failure data indicating that the power supply has stopped to the first processing device 2a. However, the man conveyor system 20 is not limited to such a configuration.

[0100] For example, when the second processing device 2b is powered by the storage battery 15, it may be configured to output power failure data not to the first processing device 2a (or not only to the first processing device 2a) but to the monitoring device X1. Also, for example, when the second processing device 2b is powered by the storage battery 15, it may be configured not to output power failure data to the first processing device 2a and the monitoring device X1.

[0101] (L) Further, in the man conveyor system 20 according to the above embodiment, when the second processing device 2b does not acquire the first processing data from the first processing device 2a after acquiring the power failure data from the first processing device 2a, the second processing device 2b outputs the first processing stop data and the power failure data to the monitoring device X1. However, the man conveyor system 20 is not limited to such a configuration. For example, when the second processing device 2b does not acquire the first processing data from the first processing device 2a after acquiring the power failure data from the first processing device 2a, it may be configured to output the first processing stop data to the monitoring device X1 and not output the power failure data to the monitoring device X1.

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

[0103] (N) Note that, for example, in the system, method, program, and apparatus shown in the claims, specification, and drawings, the execution order of each process such as operations, procedures, steps, and stages can be realized in any order as long as the output of the previous process is not used in the subsequent process. For example, even if it is described for convenience using "first", "next", etc., it does not mean that it is essential to execute in this order.
