[Background Art] Equipment such as elevators and passenger conveyors installed in buildings are maintained in a safe operating state by regularly performing maintenance and inspection work at intervals of a predetermined cumulative operating time. is necessary. Therefore, in order to know when to perform maintenance and inspection work, terminal devices have been placed in buildings that capture and store operating data from equipment installed in the building. This terminal device includes measuring devices such as a frequency meter that counts the number of times each equipment is activated and a cumulative hour meter that counts operating hours, and a device that detects when the data of these measuring devices reaches a preset value. There are detectors and alarms installed. Further, the terminal device is connected via a communication line to a monitoring center provided at a remote location that centrally monitors a plurality of terminal devices.

[Problems to be Solved by the Invention] In the conventional method described above, when a request for maintenance and inspection work is generated, a maintenance request signal is sent from the terminal device to the monitoring center. It is not possible to grasp the schedule and schedule maintenance and inspection work. For this reason, the monitoring center must always have a number of maintenance and inspection workers on standby at all times, the number of which is expected to be necessary based on the track record of conventional maintenance and inspection work. Furthermore, as equipment gets older, it is naturally necessary to change the limit values that form the basis of the maintenance inspection requests, but conventionally, maintenance inspection workers go to the site and change the limit values for each piece of equipment. It was necessary to carry out complicated work over a considerable period of time.
