Abstract：Based on the topographic features of coal mine and its gas distribution, a scheme via ZigBee-based wireless sensor network which was applied in coal mine safe system was proposed. In this scheme, ZigBee-based wireless sensor network, which consisted of sensor nodes, data sinks and one coordinator, realized several kinds of safe index information gathering and transporting in coal. Introduced the structure of ZigBee-based wireless sensor network, the hardware structure of sensor node and software communication process between each two ZigBee modules in detail. Due to the application of ZigBee technology in coal safe system, the system has characteristics of low consumption, low cost, high flexibility and expansibility.
