Elevator control system with self-diagnosis and self-adjustment functions and monitoring method

Abstract

The invention provides a monitoring system for automatically monitoring elevator faults. The monitoring system comprises an input current monitoring sensor, an input rectifier bridge, a switching tube, an output current monitoring sensor, an encoder, a vibration sensor and a main control board. The current monitoring sensor, the input rectifier bridge, the switching tube and the output current monitoring sensor are electrically connected in sequence, and the input current monitoring sensor and the output current monitoring sensor are electrically connected with the main control board; the vibration sensor and the encoder are both connected with the main control board. According to the elevator vibration fault prompting system, abnormal monitoring of elevator vibration is achieved, interference is reduced by filtering the current frequency and the working frequency of the motor, the accuracy of elevator vibration fault prompting is improved, and using safety of an elevator is guaranteed.

Description

technical field [0001] The invention relates to the technical field of elevator control systems, in particular to an elevator control system with self-diagnosis and self-regulation and a monitoring method. Background technique [0002] In the current elevator system, the current acquisition loop and the encoder signal acquisition loop are set with fixed hardware and software filtering parameters of a certain two frequencies; when the elevator is running, the power supply and encoder signal acquisition loop are affected by multiple different frequency bands. When there is interference, the elevator system cannot effectively filter out the interference, resulting in abnormal vibration of the elevator. Contents of the invention [0003] The first purpose of the present invention is to overcome the deficiencies of the prior art and provide a monitoring system for automatically monitoring elevator faults, which can effectively monitor elevator vibration and realize fault prompt...
