煤矿主扇风机在线监控系统设计研究

摘要

By taken ventilator of the mine as an example, the paper select the S7-300 processor and the other module to establish the PLC PC hardware system, and then analyzes the measurement methods of each parameter in fan, and determines the sensor selection. Finally, it estab-lishes communication mechanism of data resource configuration and the software structure of the computer monitoring software design. the main fan monitoring and control system based on OPC communication protocol is established.%本文将某矿主通风机作为实例进行分析，首先选择S7-300处理器以及其他模块，建立了PLC上位机硬件系统，接着分析了风机运行各参数的测量方法，并确定了传感器的选型，最后从通信机制建立、数据资源配置及软件结构三方面进行了上位机监控软件设计，最终建立了基于OPC通信协议的主扇风机监测控制系统。
