数据融合在列车定位系统中的应用研究

Research on the Application of Data Fusion in Train Positioning System

数据融合技术是对多个传感器提供的信息按某种最优融合准则进行融合，能够提高数据的精确度。本文总结了数据融合在RUNE、ITCS及GLLS等国内外典型列控系统研究中的应用情况，并根据上述几个典型系统研究的测试结果，分析了数据融合在列车定位中应用的有效性和优越性；最后对数据融合在列车定位中的应用进行了展望。

Data fusion technology is to fuse information provided by different sensors according to the best fusion rule ; it can improve the accuracy of data. This paper summarizes the application of data fusion in RUNE, ITCS and GLLS and other domestic and international typical train control system research. According to the test results of the above several typical systems, the effectiveness and superiority of data fusion in train locating application is ana- lyzed. Finally, it predicts the application of data fusion in train locating.
