Motor multi-parameter measuring and monitoring system

Abstract

The invention relates to a motor multi-parameter measuring and monitoring system. The system comprises an ampere meter, a voltmeter, a vibration sensor, a temperature sensor, a computer in a central control room, an anti-interference module, a remote I / O module and an industrial local area network all on a motor site. The ampere meter, the voltmeter, the vibration sensor and the temperature sensorare connected with the anti-interference module through signal lines, the anti-interference module is connected with the remote I / O module through a signal line, and the remote I / O module is connected into the industrial local area network through a network cable. According to the invention, data signals collected by instruments and meters on the motor site firstly pass through the anti-interference module, then the signals are transmitted to the remote I / O module through the signal line, the remote I / O module converts electric signals of an instrument into network signals, the network signals are input to the industrial local area network through the network cable, the computer in the central control room reads the transmitted parameter signals through the network cable, the signals arestored and archived, and when the collected signals reach a set alarm value, alarm is raised, and production plan of workers is facilitated.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a motor multi-parameter measurement and monitoring system. Background technique [0002] Among the various energy sources in nature, electric energy has the outstanding characteristics of large-scale centralized production, long-distance economic transmission, and intelligent automatic control. It has not only become the main energy source for human production and life, but also played an important role in the emergence and development of modern human civilization. Correspondingly, as the core equipment for electric energy production, transmission, use and transformation of electric energy characteristics, motors are also occupying an increasingly important position in all industries and departments in modern society. [0003] For the power industry itself, the motor is the main equipment of power plants and substations; in the machine manufacturing industry and all oth...

Problems solved by technology

[0004] Therefore, it is particularly important to measure various parameters of the motor during operation. The motor parameters during operation, such as current, voltage, temperature, vibration and other data must be manually detected at all times, so that the staff can understand the operation of the motor; In the factory, the data of various parameters are collected at the motor site through the primary instrument, and displayed on the secondary instrument in the instrument room through the signal line. The staff need to read the meter at regular intervals, which consumes a lot of labor costs; At the same time, many parameter signals are 4-20ma signals, which are easily affected by various high-voltage circuits and frequency converters on site, resulting in inaccurate collected signals
