Improvement of underground personnel location algorithm based on ZigBee network environment
This article mainly optimizes a positioning algorithm for underground personnel based on the particularity of the underground environment,and tests the accuracy of the algorithm through simulation.During the positioning process,it is necessary to obtain the environmental parameters of the current target base station to determine which positioning algorithm is suitable for use in order to improve the positioning accuracy using the optimal positioning algorithm in different situations.The obtained data is uploaded through the ZigBee wireless network ad-hoc network function,and the positioning error is sim-ulated using Matlab in the background,The simulation results show that when obtaining the location information of any fixed target base station,the position coordinates of the mobile node can be accurately calculated,and the average error of the sim-ulation is controlled between 0.41 meters and 0.85 meters,which greatly improves the positioning accuracy compared to tra-ditional positioning algorithms and existing underground personnel positioning algorithms.
