The Research of Coal Mine Location Technology Based on the Ultra-Wideband Wireless Sensor Networks
Ultra-wideband (UWB) technology has the characteristics which other wireless communication technology can not match to. It combines with wireless sensor network (WSN) technology, using in the environment of coal mine underground, to achieve safety monitoring by WSN node location. Using appropriate location algorithm can not only improve the location accuracy of the calculation can also reduce system cost and power consumption. This paper mainly describes the basic nodes location principle and algorithm of WSN, proposes the location algorithm which is suitable for coal mine environment, and improves it based on traditional ranging and location method. Simulation results show that the improved location algorithm effectively improves location accuracy and location performance of the node.
