A roadway abscission monitoring system based on WSNs is designed

aimed at the state of lineate most coal mine roadway abscission layer monitoring at present.The stucture of the system is introduced and also the software and hardware designs and the work process which uses CC2430 as the sensor node and uses CC2430 and MCP2515 as the core of the sink node.Through the underwell experiments in coal mine

the transmission characteristics at 2.4 G is determined.The abcission layer status of the roadway under-well is determined real-time and reliable

while the distance between two wireless sensor nodes is 15 meters.
