摘要
为了提高煤矿井下人员定位系统的精确度,以及降低其成本,提出了基于Zigbee技术的低功耗煤矿井下人员定位系统。本系统采用低功耗的Zigbee无线标识卡和读卡器,基于三边测距的高精度定位算法,井下部分采用高可靠性的CAN现场总线方式进行组网。实验结果证明,本系统在楼道中的静态定位平均误差为2.5 m,具有很好的定位性能。
To further enhance precision of personnel positioning system in underground coal mine, andreduce cost of system, a method of mine personnel positioning system with low-power dissipation basedon Zigbee wireless technology is presented. This system adopts wireless electronic tags and card readerswith low-power dissipation based on Zigbee technology and high accuracy location algorithm based on three-dimensional positioning method, and uses CAN bus method to organize net on underground mine. Experimental results show that positioning error tested in corridor of floor is less than 2.5 meters. The experimental performances illustrate that positioning system has good positioning performance.
