BDS／GP S双模定位技术在现代有轨电车中的应用研究
Application researth on BDS/GPS dual-mode positioning technology for modern streetcar
摘要
Abstract
Real-time positioning and monitoring system is an essential component of modern tram operation con-trol system,which is a vital system to ensure operating safety of modern tram.In view of the shortcomings of tra-ditional GPS positioning,a high precision positioning system of modern tram based on BDS/GPS dual mode posi-tioning technology was studied.A new positioning scheme that is depent on BDS/GPS dual mode positioning mainly,RFID/DR secondarily in different track section was put forward in this paper.Additionally,a combina-tion of median filtering and Kalman filtering algorithm was proposed to improve the accuracy of dual mode positio-ning information.The result proves that the proposed method is more accurate and reliable than the traditional GPS positioning system,and can ensure the safe operation of modern tram.关键词
