Abstract: A wireless global positioning algorithm of the mine personnel of which the segmental serials can be dynamically identified is presented. Cutting the roadway into some segments according to their terrains, and building a local coordinate system on each segment of the roadway, the wireless global positioning of the mine personnel through a series of local coordinate transformations has been achieved. This paper discusses in detail three typical roadway terrain models, the corresponding local coordinate systems and the determination methods of the coordinate parameters, and elaborates the dynamically identifying methods of the serials for each piece of split local coordinate system in the roadway. Simulation for the global positioning algorithm is done in wireless radio network, and the results show that the proposed mine personnel wireless global positioning algorithm has higher stability and positioning accuracy.

摘要： 提出一种段序号可动态识别的矿井人员无线全局定位算法。把巷道按其地形特点切成段，每一段巷道上建立一个局部坐标系，通过一系列局部坐标变换实现矿井人员无线全局定位。详细论述了三种典型的巷道地形模型及相应的局部坐标系和坐标参数的确定方法，阐述了被切分的每一段巷道局部坐标系序号的动态识别方法。对该全局定位算法在无线射频网络中进行了仿真，结果表明，所提出的矿井人员无线全局定位算法具有较高的稳定性和定位精度。
