Principle of Underground Personnel Positioning System Based on RSSI and Its Desig

Abstract

The paper proposed a design scheme of underground personnel positioning system based on RSSI, expounded mathematical modeling method of underground tunnel and the basic theory of personnel positioning, and mainly introduced implementation schemes of hardware and software of the underground personnel positioning system. The system realizes real-time functions of tracking and positioning of underground workers by layouting wireless sensors at some key measurement points to get RSSI information.
