Abstract

The invention provides an online detection system for vibration of an elevator traction motor, which is characterized by comprising a sensor, a signal processing module, a data processing module, an alarm device, a motor control device and a power supply, wherein the power supply provides electric energy for all electrical components of the detection system; the sensor is used for collecting a vibration signal of the traction motor; the signal processing module is used for acquiring and amplifying data acquired by the sensor; the data processing module is used for storing, analyzing, displaying and judging the processed signal data; and the data processing module is in signal connection with the alarm device and the motor control device. The beneficial effects of the invention are that bymeans of fixing external equipment at a to-be-detected point of the motor, the detection equipment is convenient to disassemble, and the maintenance cost is low; and through information acquisition and analysis of regular change of current flowing through a capacitor line, the fact that the motor works abnormally is discovered at the first time, and the detection principle is simple.

Description

technical field [0001] The invention relates to the field of motor monitoring, and relates to an on-line vibration detection system of an elevator traction machine. Background technique [0002] As an important power output and transmission equipment in the elevator system - traction machine, if there is a problem, it will inevitably affect the operation of the elevator and the personal safety of the passengers. Through the vibration detection of the traction machine, the data is extracted and analyzed, and the fault judgment and early warning functions can be performed. Existing traction machine vibration detectors generally have complex structures, and the measured vibration data is also relatively complex, which cannot simply and clearly reflect the working conditions of the traction motor. Contents of the invention [0003] The present invention provides an elevator traction motor vibration on-line detection system, including a sensor, a signal processing module, a da...
