FIG. 1 is a diagram for explaining the configuration of a man conveyor remote monitoring system according to Embodiment 1 of the present invention, and FIG. 2 schematically shows the configuration of the upper machine room in the man conveyor remote monitoring system according to Embodiment 1 of the present invention. FIG. 3 is a diagram for explaining an antenna mounting structure in the man conveyor remote monitoring system according to Embodiment 1 of the present invention.

In each of the drawings, an escalator 1 as a man conveyor is configured such that a pair of balustrades 3 are erected on both sides of a footboard 2 on which a passenger rides, and a moving handrail 4 is disposed on a peripheral portion of each balustrade 3. A drive motor 8 and an upper footboard sprocket 9 are built in the upper machine chamber 6 in the truss frame 5 of the escalator 1. A lower tread plate sprocket 10 is built in the lower machine chamber 7 in the truss frame 5. An endless drive chain 11 is wound around the drive motor 8 and the upper tread board sprocket 9, and an endless tread board chain 12 is wound around the upper tread board sprocket 9 and the lower tread board sprocket 10.
Further, the moving handrail drive sprocket 13 is integrally mounted with the upper tread plate sprocket 9. A moving handrail drive mechanism (not shown) is disposed in the truss frame 5, and power is transmitted through a moving handrail chain 14 wound around the moving handrail drive sprocket 13. ing.

  An escalator control panel 15 is installed in the upper machine room 6, and a monitoring device 16 is connected to the escalator control panel 15 and installed in the upper machine room 6. The escalator control panel 15 controls the operation of the escalator 1. The monitoring device 16 includes a microcomputer including a CPU, a ROM, a RAM, and a communication unit, and monitors the operation state of the escalator 1 and also monitors a monitoring center 20 such as a management room in the building or an external maintenance company. Send and receive monitoring information. A transmission / reception antenna 17 is installed in the boot 18 of the inlet portion, and is connected to the communication means of the monitoring device 16 by a wiring 19.

In the escalator remote monitoring system configured as described above, the escalator control panel 15 controls the operation of the escalator 1 based on an output signal of a power switch (not shown) of the escalator 1.
When the power switch is turned on, the drive motor 8 is driven. The power of the drive motor 8 is transmitted to the tread plate sprocket 9 through the drive chain 11, the tread plate chain 12 travels, and the tread plate 2 moves. At the same time, the power of the drive motor 8 is transmitted to the movable handrail drive sprocket 13 and is transmitted to the movable handrail drive mechanism through the movable handrail chain 14. Thereby, the moving handrail 4 moves in synchronization with the footboard 2.

Although not shown, the escalator 1 is provided with an abnormality detection device that detects an abnormality of the device, and the escalator control panel 15 monitors an output signal from the abnormality detection device.
When an abnormality occurs, the escalator control panel 15 determines the occurrence of the abnormality based on the output signal from the abnormality detection device, stops driving the drive motor 8 and stops the escalator 1, and indicates an abnormal state. Data is transmitted to the monitoring device 16. When the monitoring device 16 receives the data indicating the abnormal state, it activates the communication means and transmits the data indicating the abnormal state to the monitoring center 20 via the antenna 17.

  Thus, the antenna 17 is built in the boot 18 of the inlet part outside the upper machine room 6 having poor sensitivity for radio wave transmission / reception. Therefore, the sensitivity of radio wave transmission / reception is improved, and radio transmission / reception between the monitoring device 16 and the monitoring center 20 is reliably performed. Moreover, mischief of a third party can be prevented.

Embodiment 2. FIG.
FIG. 4 is a diagram for explaining the configuration of a man conveyor remote monitoring system according to Embodiment 2 of the present invention.

And if the arrival of a user is discriminate | determined based on the output signal of a photoelectric device, the drive motor 8 will be driven and an escalator will be drive | operated.
When an abnormality occurs, the escalator control panel 15 determines the occurrence of the abnormality based on the output signal from the abnormality detection device, stops driving the drive motor 8 and stops the escalator 1, and indicates an abnormal state. Data is transmitted to the monitoring device 16. When the monitoring device 16 receives the data indicating the abnormal state, the monitoring device 16 operates the communication unit and transmits the data indicating the abnormal state to the monitoring center 20 via the antenna 17.

  Also in the second embodiment, the antenna 17 is built in the photoelectric device post 21 outside the upper machine room 6 having poor sensitivity for transmission and reception of radio waves. Therefore, the sensitivity of radio wave transmission / reception is improved, and radio transmission / reception between the monitoring device 16 and the monitoring center 20 is reliably performed. Moreover, mischief of a third party can be prevented. Further, the wiring 19 can be laid using the same path as the wiring connecting the escalator control panel 15 and the photoelectric device post 21.

In addition, although each said embodiment demonstrated as what applies to an escalator, even if it applies this invention to man conveyors other than an escalator, for example, a moving walk, the same effect is acquired. Here, the tread surface on the moving sidewalk is not a step shape like an escalator, but a flat shape, and is a pallet type or rubber belt type tread board.
Further, in each of the above embodiments, the monitoring device 16 and the escalator control panel 15 are configured separately, but the monitoring device 16 may be configured integrally with the escalator control panel 15.
