BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention monitors the operation of an elevator installed in each building by utilizing a communication line, and periodically dispatches maintenance personnel to each building to operate the elevator. The present invention relates to an elevator remote monitoring system for performing inspection work.

[0002]

2. Description of the Related Art Elevators installed in various buildings and used by an unspecified number of people are obliged to perform maintenance and inspection at regular intervals in order to ensure the safety of users. In addition, in order to avoid the situation where the user is locked in the elevator car for a long time due to a sudden power failure or failure, the operating state of the elevator is constantly monitored, and when an abnormality occurs, Are required to have a system where personnel (maintenance staff) can immediately rush to the site.

Since it is necessary to be familiar with the structure and operation of the elevator in order to perform maintenance and inspection of the elevator and to cope with sudden abnormalities, the building owner and the building management company specialize in the maintenance of the elevator. The maintenance company will be entrusted with regular maintenance and inspection of this elevator.

The elevator maintenance company, which is entrusted with the periodic maintenance and inspection of the elevator by the building owner, building management company, etc., regularly sends the maintenance personnel to the contracted building and asks the maintenance personnel to do so. The elevator is being maintained and inspected.

In order to efficiently carry out the inspection work of the operation of the elevator by the maintenance staff, an inspection terminal device which outputs various signals for inspection to the drive control device which controls the vertical movement of the elevator car. Is equipped with.

Then, the maintenance staff operates and inputs various inspection execution commands to the inspection terminal device. Electronic inspection information such as car moving speed, hoisting motor current, voltage, etc., other than the inspection results that need to be visually confirmed by maintenance personnel, can be obtained from the elevator via a communication line such as a public telephone line. It is sent to the elevator service monitoring center installed in the maintenance company.

Further, a remote monitoring terminal for constantly monitoring the operation of the elevator is attached to each elevator, and the remote monitoring terminal and the elevator service monitoring center of the elevator maintenance company are connected by a communication line such as a public telephone line. Then, the elevator service monitoring center will monitor the operation of the elevators in each of the contracted buildings.
