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.
