Wireless sensor network (WSN) is increasingly popular in the field of object tracking due to its promising capability. At present, coal mine personnel positioning systems generally use radio frequency identification (RFID) technology or Zigbee technology. Such systems require complete coverage of the tunnel network by wireless measuring point. The cost of building an information network covering the whole tunnel network is too much. At the same time, a large number of measuring points and equipment can cause congestion, resulting in data delay too long, inaccurate data and so on. In this paper, a positioning system of non-complete coverage of the whole tunnel network by measuring point is proposed. The global positioning system is made up of the monitoring center, underground base stations, gateways, reference nodes and mobile nodes. Mobile nodes constantly compute their own location and send them to the monitoring center for management. In this paper, a detailed software and hardware design that involved in the global positioning system is demonstrated. Also, the acquisition, collection and release of the personnel location information and realization method are described by the numbers.
