泰国信号联锁系统中侧防条件的研究

Research on Flank Protection in Thailand Signal Interlocking System

与国内使用道岔和超限区段进行侧冲防护的方法不同,泰国信号联锁系统中仅采用侧防区段检查的方式,对进路存在的侧面冲突风险进行安全防护,且泰国信号联锁系统中侧防区段主要分为绝对侧防区段、条件侧防区段和区间侧防区段。结合国内铁路侧冲防护方案,对泰国信号联锁系统的3种典型侧防场景进行分析,总结其侧防区段的设置在联锁逻辑安全性和行车效率方面的优势和不足,为信号联锁系统侧冲防护设计提供一种新思路。

Different from the method of using points and out-of-gauge sections for flank protection in China,Thailand’s signal interlocking system only adopts the method of flank protection track inspection to protect the side conflict risk of the route.It is mainly divided into absolute flank protection track,conditional flank protection track and interval flank protection track.Therefore,combined with the domestic flank protection scheme,this paper analyzes three typical flank protection scenarios of the signal interlocking system in Thailand,and summarizes the advantages and disadvantages of the flank protection track of the signal interlocking system in Thailand in terms of the interlocking logic safety and running efficiency,and provides a new idea for the flank protection design of the signal interlocking system.
