In order to satisfy the need of short distance wireless personnel positioning, a ZigBee compliant personnel positioning system has been designed. ZigBee technology and its characteristics was been introduced,and analysed the ZigBee wireless communication protocol, and using the CC2430 chip and CC2431 chip with positioning engine. On this based, the personnel positioning system is studied and the design of hardware, software of the wireless communication application development, achieve the underground personnel positioning. It can provide abundant data, graphic information, real-time monitoring well from ground personnel,.in accordance with the actual situation of coal mine provide attendance function. After the accident, the accident can be fast retrieval when underground staff location specific distribution, so as to formulate timely and effective rescue measures. This network system satisfied the needs of the underground personnel positioning requirements of wireless short distance, low cost, convenient construction, and easy to use.
