Abstract: To monitor the environment and electric accessory under mine, sensor monitoring nodes of a wireless sensor network monitoring system send data to sink nodes, and then the data were transmitted through the sink nodes to gateway node for the implementation of communication between the wireless sensor network and external network.Finally, the remote monitoring was realized.According to the GB3836.4 IIC level of explosive gas mixture as intrinsically safety authentication target, the gateway node was designed to be ensured safety and reliable utility under mine.

Key words: Wireless sensor network, Gateway node, Intrinsically safety, Underground mine
