TSTCBTC~? 2.0系统静止列车建立定位功能的研究与实现

Research and Implementation of Positioning Function for TSTCBTC 2.0 Stationary Train

列车精确定位是CBTC(基于通信的列车控制)系统的基础。针对上海轨道交通5号线自动车辆段运营场景,分析TSTCBTC■2.0车载系统的静止列车建立定位功能。介绍了列车定位基本技术;阐述了静止列车建立定位功能的技术方案,分析了该方案存在的潜在风险及应对措施。基于TSTCBTC■2.0系统的静止列车建立定位功能,车载设备上电后能够直接建立列车定位并进入全自动驾驶模式或准全自动驾驶模式,不需要司机进行任何操作,能够保证轨道交通安全,提高运营效率。

Accurate train positioning is the foundation of CBTC(communicate based train control) system. The implementation of positioning function for TSTCBTC 2.0 on-board system stationary train is analyzed, regarding the automatic depot operating scenario of Shanghai rail transit line 5. With an introduction to the basic technologies of train positioning, the technical plan for implementing the positioning function is described, the potential risks and countermeasures of the plan are discussed. Based on the positioning function for TSTCBTC 2.0 system stationary train, when the on-board system is powered on, the train will implement the positioning function automatically and enter the FAO(fully automatic operation) or quasi-FAO mode, so as to ensure the safety and operational efficiency of rail transit without any manipulation of drivers.
