KR970065389A - Remote monitoring / diagnosis system of elevators - Google Patents

Abstract

The present invention relates to a remote monitoring / diagnosis system for maintenance and repair of an elevator, and in the prior art, there is provided a remote monitoring / diagnosing system for an elevator, comprising: 1) an indirect detecting system for monitoring an operating state of each elevator in a monitoring terminal, Therefore, when the number of elevators to be monitored is increased, the observers are complicated. In addition, since there are many restrictions on the operation information of the elevators to be collected through them, the abnormal condition detected based on the types and contents And 2) it is not easy to change the monitoring and diagnostic items, change the operating specifications, and remote control because information can not be exchanged between the control panel and the remote monitoring center of each elevator, and 3) In order to maintain the best performance, we need to However, according to the present invention, in view of this, the elevator control panel itself detects an abnormal state of itself, and immediately transmits data for diagnosis and contents to the elevator control panel The monitoring terminal monitors and records the input / output data of the elevator control panel and the history of the external states for evaluating the operation contents and the running performance of each elevator without interruption by reporting it to the remote monitoring center. If there is a request, periodically stored information is stored in the database of the remote monitoring center and analyzed to calculate the operating performance and service efficiency of each elevator, calculate the remaining service life of each part, predict the failure of the elevator So that it is always comfortable and has the best performance The.
