介绍了一种基于CC-Link的煤矿安全监控预警系统,该系统以微控制器AT89S52和通讯芯片MFP3为主控部件,利用瓦斯传感器和温度传感器采集煤矿井下的环境因子,通过监控计算机远程监测,实现井上井下联动,危险时可声光报警。应用表明:该系统使用方便、维护简单、可靠性高,特别适合煤矿瓦斯远距离监控与预警。 This paper introduces a coal mine safety monitoring and early warning system based on CC-Link. The system takes the microcontroller AT89S52 and the communication chip MFP3 as the main control components, and uses the gas sensor and the temperature sensor to collect the environmental factors in the coal mine. By monitoring the computer remote monitoring, To achieve downhole linkage, dangerous sound and light alarm. Application shows that: The system is easy to use, easy to maintain, high reliability, especially for long-distance monitoring and warning of coal gas.
