环行铁道城轨试验线列车位置实时监测方案研究

为充分利用城轨试验线线路资源,同时保障试验安全,城轨试验线急需实现列车定位功能。通过综合分析研究国内外主要定位方式的原理、特征及适用性,并结合城轨试验线的实际环境,提出将分布式光纤振动定位和卫星定位的新技术应用于城轨试验线的列车定位,为解决城轨试验线列车位置实时监测提供了切实可行的技术方案。

Real-time monitoring scheme for train position on urban rail test line of circular railway

In order to make full use of the resources of the urban rail test line and ensure the safety of the test, it was urgently needed for the urban rail test line to implement the train location function. Through comprehensive analyzing and studying the principles, characteristics and applicability of the main location methods about domestic and abroad, and combining with the actual environment of the urban rail test line, this article put forward the new technology of distributed optical fiber vibration location and satellite position to implement train location of the urban rail test line, which provided a feasible technical scheme for real-time monitoring of the train position of the urban rail test line.
