A monitoring and controlling system based on distributed industrial ring ethernet in coal mine

There are many different factors that influence the safe production of coal mine such as equipment factor, environment factor and artificial factor etc. At current, many coal mines all over the world have built up harmoniously independent mutually monitoring and controlling sub-systems based on variety communicate channels and protocols. In this paper, a monitoring and controlling framework model is built up based on industrial ring Ethernet in coal mine, four layers of network demarcation are put forward, and the method and steps of hardware and software integrates are discussed. At last, the design procedure of a drainage auto control sub-system is introduced according to the Ethernet communication technique.
