Abstract

Aiming at the problems of short transmission distance, low multipath effect and low positioning accuracy in the common tunnel personnel positioning technology, proposed a new system of personnel positioning system for subway tunnels based on the Impulse UWB (Impulse Radio-Ultra Wideband, IR-UWB). According to the characteristics of the tunnel complex environment, the system can reasonably utilize the advantages of the time difference of arrival (TDOA) and the time of arrival (TOA) to achieve a reasonable position in different parts of the whole tunnel. The whole system is to send the ranging signal to the positioning sensor through the tunnel staff who wear electronic tags, and the use of Symmetric Double-Sided Two-Way Ranging to calculate the exact position of personnel information.
