无线Mesh在采煤机远程监控系统中的应用研究

Formation of the new wireless network in underground mine face will effectively offset defects of traditional wireless technology used in underground mining, and it will enhance the reliability of wireless network. It is an important measure to realize the remote control for shearer. A kind of wireless mesh networks was built in underground mine face based on the intrinsically safe wireless mesh switchthe the group self-developed . Combing with double-loop industrial Ethernet, the communication networks of shearer control system was formed. The Wireless Mesh Network in the mine face has good performance of communication result, which can satisfy the smooth video transmission and communication distance between a single node is up to 66m.
