The Underground Personnel Positioning Algorithm Improvement Based on RSSI
According to the underground positioning system based on the RSSI algorithm is vulnerable to other node signal, as well as when measuring the distance of the underground nodes, the ranging error is brought by the underground environment, consequently the accuracy and stability of trilateral positioning algorithm is influenced.In order to solve the locating cell confusion caused by signal interference, by using the received angle information of the known nodes ,this passage divides the underground positioning into locating cells to filter the interference of other nodes.After determining the location cell, narrow the scope of location by marking the overlapping areas, use centroid algorithm of the multiple marked region, in order to improve the positioning accuracy and stability.Simulation results show: The method of underground personnel positioning processes high accuracy and strong stability, is superior than the traditional RSSI algorithm.
