In this paper, the implementation of integrated mine safety monitor system is explained. The system is composed of PC monitors, sink nodes, base station nodes and mobile nodes. The mobile node is based on ZigBee system-on-chip CC2530F256 to acquire the gas concentration and positioning signals. Those acquired signals are sent through ZigBee network to the base station node which comprises CC2530F256, STM32F107VCT6 and isolated CAN bus interfaces. After collected and processed by the base station node, signals are transmitted to the sink node. Finally, signals are sent to PC monitor through Ethernet or CAN bus network, and they are stored and displayed dynamically by PC monitors.
