Application of OPC Technology in Integrated Automation System of Mine

In order to build a kind of standard interface among application programs of automation control subsystem of coal mine, the paper proposed a design scheme of integrated automation system of mine based on OPC technology. It analyzed principle of OPC technology, introduced structure of the system, and gave concrete application of the system in Wangzhuang Coal Mine. The actual application showed that the system runs stably and reliably and can real-timely monitor main links of underground production.
