Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor management device suitable for operation management of passenger conveyors such as escalators.

[0002]

2. Description of the Related Art Generally, a passenger conveyor such as an escalator has a function of elevating a step and moving a moving handrail in synchronism with the step, and a drive control system is constituted by a relay control system. That is, it is not configured to be controlled by a microcomputer like an elevator.

An example of a conventional management system for such a passenger conveyor is disclosed in Japanese Patent Laid-Open No. 8-324945. When the safety switch for ensuring the safety of passengers is operated, this conventional technology is a monitoring panel whose operation signal is installed in the management room of the building where the passenger conveyor is equipped, and a maintenance company that performs maintenance inspection work on the passenger conveyor. It is configured to be sent to the monitoring center. Therefore, when the safety switch is activated, the building manager or maintenance personnel of the maintenance company can quickly determine whether the passenger conveyor is stopped due to the operation of the safety switch, based on the above-mentioned operation signal transmitted to the monitoring panel or the monitoring center. It can be adapted to.

[0004]

By the way, since the above-mentioned safety switch provided on the passenger conveyor does not monitor the wear and deterioration of each device provided on the passenger conveyor, the deterioration degree and the life of each device are not measured. In order to grasp the above, it is necessary to suspend the passenger conveyor and carry out the maintenance and inspection work on a regular basis, that is, regardless of whether the maintenance and inspection work is actually required. This also applies to the above-mentioned conventional technique.

Therefore, in the past, since the passenger conveyor is put into a suspended state every time such maintenance work is performed by the maintenance staff, there is a problem that the service to the users, that is, the convenience cannot be expected.

When the wear and deterioration of the equipment progresses considerably before the regular maintenance and inspection work is performed, the passenger conveyor may be broken. That is, in the past, in many cases, it was often noticed that the specific equipment of the passenger conveyor was worn or deteriorated only after the failure.

The present invention has been made in view of the actual situation in the prior art as described above, and an object thereof is to prevent a failure of a passenger conveyor in advance, and to reduce the number of times maintenance personnel perform maintenance and inspection work. It is an object to provide a passenger conveyor management device that can reduce the number of passengers.

[0008]

In order to achieve the above object, the invention according to claim 1 of the present invention comprises steps,

This device information is monitored at regular intervals or at regular intervals.
It is characterized in that it is transmitted to the visual center.

In the invention according to claim 1 having such a configuration, the state of the equipment constituting the passenger conveyor, for example, the degree of wear or deterioration of the equipment such as the speed reducer or the motor is detected by the equipment detector as detection data. Predetermined device information is created by the 1 determination means based on this detection data, and this device information is transmitted to the outside by the communication terminal device.

Therefore, from this device information, it is possible to grasp a subtle change in the device of the passenger conveyor, which is not normally noticed by the maintenance staff, without the maintenance staff performing the maintenance inspection work. This makes it possible to take measures to prevent the failure of the passenger conveyor,
It is possible to perform the maintenance and inspection work by the maintenance personnel at an appropriate time, and it is possible to reduce the number of times the maintenance personnel perform the maintenance and inspection work.

Passenger conveyor 1 that has been stopped after returning from a faulty state
Can be restarted. Also, the second switch 5b
When the classification information is output to the monitoring center 16, the monitoring center 16 gives a quick instruction to the maintenance staff of the maintenance company, and the maintenance staff carrying the pager 17 also operates the second switch 5b. It is possible to know that the operation has been performed, and immediate close correspondence can be made between the monitoring center 16 and the maintenance staff. Therefore, at this time, the maintenance staff immediately goes to the building where the corresponding passenger conveyor 1 is provided, performs necessary maintenance and inspection work, restores the passenger conveyor 1 from the fault state, and restarts the stopped passenger conveyor 1. Can be made.

Even when the above-mentioned first switch 5a which can be restored and restarted by the manager operates, the classification information is transmitted to the monitoring center 16 and the pager 17. As a result, the monitoring center 16 and the corresponding maintenance personnel can know that the first switch 5a has operated and can take necessary necessary measures thereafter.

The operation history information of the safety switch 5 described above is stored in the second storage means included in the storage means 8b of the sensor terminal device 8. Therefore, the monitoring center 16
Can read the operation history information of the safety switch stored in the above-mentioned second storage means through the telephone line 18 and the communication terminal device 9, and the maintenance staff who carries the mobile terminal device 12 can By connecting the input terminal 14 of the mobile terminal device 12 to the output terminal 13, the operation history information of the safety switch 5 stored in the above-mentioned second storage means can be read, and necessary measures are taken.
