摘要
介绍了我国现有列车定位方法,简要阐述了基于网络的无线定位方法及其定位参数的测量与估计。结合铁路交通中的具体情况,分析适用我国铁路的列车无线定位技术以及确定定位点的图解方法,并分析了影响列车无线定位精度的因素,最后对列车无线定位的抗干扰措施进行了探讨。
The basic methods of train positioning were introduced and a mobile positioning approach to measure and estimate position parameters via network was explained. According the specific situation of railway traffic, applicable mobile train positioning techniques were analyzed and their schematic methods to locate the trains were given. The factors which affect the precision of mobile positioning were analyzed. Finally, it discussed the anti-interference measures for mobile train positioning.
