Design of Positioning System for Underground Personnel and Electromechanical Equipment Using WSN

Aiming at the problems of low accuracy and poor stability of the current real-time positioning system of coal mine personnel and electromechanical equipment, wireless sensor network positioning system based on UWB is designed and implemented. The system combines the TWR (Two Way Ranging) algorithm with the trilateration positioning algorithm to realize the calculation of position information, reduce the amount of system calculation, and improve the positioning accuracy. Experimental results show that the system has the characteristics of small communication volume and high positioning accuracy.
