一种基于GPS/DR/MM组合的列车定位方法研究
Train integrated positioning method based on GPS/DR/MM
摘要
Abstract
In view of the train problems of poor positioning accuracy and poor real-time ability, a train positioning system framework based on the combination of GPS/DR/MM was introduced. At the same time, the processing train positioning data was disposed by using discrete stationary wavelet transform and Kalman filtering method. The discrete stationary wavelet transform was introduced to make up the shortcomings of the nonlinear difference of the Kalman filter which needs to establish accurate mathematical model of the system, thereby reducing the state estimation error of the location data. Through the combined positioning method of GPS/DR/MM which contains negative feedback regulation mechanism to correct the cumulative error of DR, the accuracy of train positioning was improved, and the system had access to the location of the train information timely, accurately and reliably. Experimental examples show that the method can meet the requirements of continuous and high-accuracy positioning of train, which has the reference value for the practical engineering application.关键词
