摘要:
为保障城市轨道交通交流供电模式下列车安全、可靠、平稳自动过分相，降低建设投资，依据TB/T 3483—2017《CTCS-3级列控车载设备技术标准》对自动过分相的规定，结合城市轨道交通线路站间距小、无电分相区数量少的特点，综合考虑实施成本，阐述了无源RFID(射频识别)精确定位技术的组成、原理及优势，从系统组成、工作原理及设备配置等方面研究了基于无源RFID精确定位技术的车载自动过分相控制系统，并详细分析了特殊工况下的过分相方案。该方案适用于城市轨道交通交流供电模式下的自动过分相场景。

In order to ensure the safety, reliability and stability of automatic phase transition of urban rail transit trains under AC power supply mode, and to reduce construction investment, according to the regulations of automatic phase transition of TB/T 3483-2017 CTCS-3 Train Control Equipment Technical Conditions, comprehensively considering the characteristics of small station intervals and small number of neutral zones along urban rail transit line routes and the implementation cost, the composition, principle and advantages of passive RFID (radio frequency identification) precise positioning technology are expounded, then the auto-passing neutral zone control system based on RFID precise positioning technology is studied from the aspects including system composition, working principle and equipment configuration. Passing neutral zone scheme under special working conditions is analyzed in detail. The scheme is suitable for the urban rail transit scenario of auto-passing neutral zone under AC power supply mode.
