基于Modbus通信方式的煤矿压风机集控系统优化研究

Optimization of Pressure Fan′s Centralized Control System Based on Modbus Communication

煤矿开采中压风机的使用十分普遍,压风机在清除易燃易爆气体、保持环境中温度、湿度等方面都有积极影响。针对压风机监控系统中信号传输效率低、准确度不足等问题,利用Modbus作为通信系统传输协议,以PLC技术为核心,对传统监控系统进行集控改造。介绍集控系统的整体结构,并对配套的通信系统设计、关键软件模块设计进行具体分析,集控系统能够实时获得压风机工作参数,并将参数显示在控制中心,监控效果良好。

The use of pressure fan is very common in coal mining, and pressure fan has a positive impact on clearing flammable gases, maintaining environmental temperature, humidity, etc. Aiming at the pressure fan monitoring system′ s low signal transmission efficiency, lack of accuracy and other issues, use Modbus protocol as a communication system and use PLC technology as the system core, to transform the traditional control monitoring system. Then describe the overall structure of the centralized control system, and introduce the supporting communication system design, key software modules design. The centralized control system can obtain pressure fun′ s operating parameters real-time and the parameters are displayed in the control center, which makes the monitoring effect is good.
