Low-voltage board cabinet informatization acquisition system based on onsite bus technology

Abstract

The invention provides a low-voltage board cabinet informatization acquisition system based on an onsite bus technology. The system comprises a low-voltage board cabinet, a controller module, a man-machine interface module, terminal equipment and an onsite button box. The controller module is embedded in the low-voltage board cabinet. An onsite signal or an internal signal received by the low-voltage board cabinet is transmitted to the controller module by an onsite bus module via an onsite bus. The controller module communicates with the man-machine interface module via an industrial ethernet. The onsite button box is connected with the low-voltage board cabinet via an onsite control loop. The terminal equipment is connected with the low-voltage board cabinet via a main loop. An original low-voltage board cabinet system and a computer control system are combined so that consumption of cables is reduced and nonferrous metals are saved; cabinet bodies are reduced, onsite space is saved and construction cost is lowered; signal transmission is performed via the bus, interference is reduced and signal quality is enhanced so as to be suitable for the requirement for sustainable development; and equipment cascading is supported and automatic control is realized.

Description

technical field [0001] The invention relates to a low-voltage panel information acquisition system based on field bus technology. Background technique [0002] Since the 1980s, my country has introduced different types of low-voltage switchgear from foreign countries with engineering projects. In the 1990s, foreign companies carried out their low-voltage complete sets of equipment in my country for sole proprietorship or joint venture production. The foreign advanced technology represented by MNS and Equipment continues to enter our country. Looking at foreign low-voltage switchgear, it is not difficult to find that they have made great breakthroughs in cabinet design, equipment arc fault protection, processing technology, and switchgear intelligence. After entering the 1990s. On the basis of centralized monitoring of the low-voltage power supply system, major foreign companies are actively carrying out research on intelligent low-voltage switches and intelligent low-voltage...
