基于ZigBee的煤矿井下人员定位系统

Personnel positioning system of underground coal mines based on the ZigBee technology

本文基于ZigBee无线网络通信技术的研究,设计了一种煤矿井下人员定位系统。采用微功率无线收发器(基站)可以实时对井下佩戴微功率定位信号发射机(电子身份卡)的工作人员进行定位、身份识别、运动轨迹查询。一方面实现了井下人员的考勤,另一方面为查询矿井中的人员分布情况提供了依据,适用于各类环境下煤矿的安全管理。

In this article ,through the research on ZigBee wireless network communication technology,a coal mine personnel position-ing system has been designed. It can position and identify timely the underground staff who wear the micro-power signal transmitter（electronic identity card） by applying the micro -power wireless transceiver （base station）. The information collected by the radiotransceiver are transmitted to the ground through the wireless network or CAN bus ,which on one hand achieve the Undergroundstaff attendance statistics,and on the other hand provide the evidence of checking the coal mine staff distribution. It can also realizethe efficient rescue and apply to coal mine security management in any circumstances.
