现代有轨电车信号系统设计研究

On the Signal System Design in Modern Tramcar Project

提出了确定有轨电车列控方式的原则和影响因素。针对车载遥控道岔方案存在的安全隐患提出了改进方案,设计了联锁控制方案;对三种道岔控制方案进行分析并给出了适用条件。提出了GPS(全球定位系统)定位结合无线通信的列车定位方案,与计轴方案进行了技术分析和比较。结合北京现代有轨电车西郊线进行信号系统设计,确定了司机人工控制方式,给出了联锁集中控制方案及GPS结合无线通信的列车定位方案;针对地下隧道提出了应用航位推算技术的解决方案。

Principles and impact factors in the selection of train control mode are proposed.Based on the hidden risks,the improvement plans for the on-board remote control of railway switch and interlocking control scheme are designed,the application conditions are summarized after a thorough comparison of three switch control schemes.A train location method that combines wireless communication with GPS positioning method is put forward and compared with the axle counter method for a detailed technical analysis.The manual train control mode and interlocking control are determined in the signaling system design according to the features of the modem tramcar project in Beijing West suburb.Finally,the dead reckoning technology is recommended in underground tunnel conditions.
