摘要
从国内外列控系统发展出发,比较分析了各种列车定位技术优缺点,结合高速列车定位趋势,剖析组合定位及GNSS导航特点。在此基础上,提出基于GNSS的高速列车组合定位方案,并对其可靠性、精确性、完整性等关键问题进行了探讨,为高速列车控制过程建模与优化探索新的途径。
This paper introduced the evolution of train control system and train location methods. According to comparative research on train location methods, it is shown that multi-sensor information fusion based train location methods and GNSS is the research direction in future. Then the constructive structure of high-speed train integrated positioning system based on GNSS is presented, and its key problems are studied including reliability, accuracy and integrality,which will give the process modeling and optimization of high-speed train control system a new and available approach.
