Realization of Fast Power Off in Another Place in Coal Mine

The paper proposes a kind of power off in another place based on Ethernet + field bus communication mode in coal mine, analyzes the principle of this kind of pattern implementation, and simply introduces methods of how to improve a serial port to discriminate power off data in another place. Field test shows that the module is suitable for the remote monitoring of the existing safety monitoring system, which greatly reduces the time of power off.
