Description

  The present invention relates to an elevator monitoring system, an elevator monitoring apparatus, and an RFID tag that transmit and receive information related to maintenance and inspection of the elevator.

  2. Description of the Related Art Conventionally, workers who maintain and inspect elevators such as elevators generally visit a plurality of sites during a day and perform maintenance and inspection operations at each site. Maintenance inspection work is scheduled in advance and is usually managed so that an operator moves along a predetermined patrol route at predetermined time intervals.

  In order to perform such management, the worker calls the monitoring center at the start of work on the site, and communicates the name, information on the site where the work is to be performed, and the start of the work on the site. The information on the site where the work is performed includes, for example, the address of the building where the elevator is installed and the name of the building. When a plurality of elevators are installed on the premises of this building, the worker also transmits information on the elevator units to the monitoring center.

Then, the operator of the monitoring center records the telephone communication items (the name of the worker, the location where the maintenance / inspection work is started, and the start of the maintenance / inspection work at this location).
Such a transmission procedure and a recording procedure at the monitoring center are also performed at the end of the maintenance / inspection work, and are also performed at the start and end of the maintenance / inspection work at other destinations.

Further, as a technique for grasping the movement of the worker on the monitoring center side as described above, for example, as disclosed in Patent Document 1, a worker carries a GPS receiver, and the current position information obtained by the GPS receiver is obtained. Some are sent to the monitoring center.
JP-A-9-107410

  However, in the management method as described above related to the maintenance and inspection work, an on-site worker must make a telephone call to the monitoring center for each work at each site. The elevator has a function of transmitting a signal including information indicating this, that is, a so-called stop notification signal to the monitoring center when the operation of the control panel is stopped. The operation stop includes a stop for maintenance and inspection work by an operator and an operation stop due to an elevator equipment abnormality.

  Therefore, when a stop notification signal is received at the monitoring center and there is no telephone call from the worker to the monitoring center, the operator determines whether the stop signal is sent for maintenance or inspection work or because of an elevator problem. In order to do this, it is necessary to grasp the inspection work schedule of the elevator that sent the stop signal.

  Further, with the technique disclosed in Patent Document 1 described above, it is possible to know the current position information of the worker on the monitoring center side, but the monitoring center side grasps the status of the elevator maintenance inspection work at this position. I can't do it.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator monitoring system, an elevator monitoring device, and an RFID tag that can easily obtain information related to the maintenance / inspection work in the elevator for maintenance inspection.

  That is, the elevator monitoring system according to the present invention is a system having a portable communication terminal device and an elevator monitoring device, and the portable communication terminal device is moved from an RFID tag provided at an installation location of an elevator to be maintained and managed. The information for identifying the installation location of the mobile phone is read, the information obtained by reading is transmitted, and the elevator monitoring device receives the information transmitted by the portable communication terminal device, and performs display control of the received information.
