A sensor-based vibration monitoring device

Abstract

The invention relates to a vibration monitoring device based on sensors. The vibration monitoring device is mainly composed of a vibration analysis computer, a device control system, a programmable logic controller (PLC), time-division vibration measuring modules, vibration sensors, a rotating speed sensor and a temperature sensor. Due to the fact that an existing vibration monitoring system is high in technical content and price, on the basis of a fault character of operation equipment, the vibration sensors are arranged in a grouping mode, a method of polling collection is used, the vibration analysis computer and the PLC or a PLC of the device control system is connected with multiple time-division vibration measuring modules, a channel of each time-division vibration measuring module corresponds to a group of vibration sensors, the PLC controls equipment which is communicated with each vibration sensor in a time-division mode, and therefore on-line vibration detection of faults of low-cost equipment is achieved, and requirements on universality of equipment vibration detection of industrial and mining enterprises are met to the largest extent.

Description

technical field [0001] The invention belongs to the technical field of equipment detection and control in industrial and mining enterprises. . Background technique [0002] As we all know, vibration detection is of great significance for the alarm and early warning of operating equipment failure. At present, the equipment of industrial and mining enterprises is equipped with a relatively complete equipment control system. For example, cement, steel, petrochemical, electric power and other industries are equipped with advanced equipment control systems. In particular, important operating equipment such as mining machinery, transportation machinery, hoisting machinery, water pumps, ventilators, and compressors in mines have been equipped with relatively complete equipment control systems, and most mines have also built comprehensive automation systems based on mine ring networks to realize Centralized monitoring and comprehensive management and control of the entire mine (a...
