Design of Mine Communication Sub-station Based on W77E58

In recent years,coal mine safety monitoring system has developed in intelligent direction.Communication sub-station is the bridge between the underground intelligent sensors and the ground monitoring computer.In this paper,the communication sub-station in coal mine based on W77E58 was introduced.The intelligent sensors in the same monitoring line were connected to a communication sub-station;the communication sub-station completed the measurement data reception,storage and transmission to the ground monitoring computer.
