基于FPGA的UWB隧道内人员定位系统设计与实现
Design and implementation of UWB tunnel personnel positioning system based on FPGA
摘要
Abstract
The communication signal used in domestic tunnel construction is not good and fails to provide accurate positioning signal.Therefore,by taking the field-programmable gate array(FPGA)as the main control hardware,a wireless transmission positioning system based on ultra-wide band(UWB)positioning technology is proposed.The basic principle of UWB positioning is based on the trilateral measurement algorithm and the adaptive Kalman filter is introduced into the back-end data processing to further improve its positioning accuracy.At the level of hardware,the system has the advantages of low power consumption and high efficiency.At the level of algorithm,the Kalman filter can make the system achieve higher accuracy.Its static ranging accuracy can reach 0.1 m,and its dynamic ranging accuracy can reach 0.2 m.The system can position the staff for a long time with high precision and high efficiency.The experimental results show that the proposed system can track and locate personnel accurately in time without network,so it has strong robustness.关键词
