站内咽喉区道口与计算机联锁结合研究及应用

结合工程实例,对站内咽喉区道口接近通知时间、接近通知点及道口信号机位置等方面进行分析研究,提出咽喉区道口信号与车站计算机联锁系统结合方案、接口技术条件及电路,通过计算机联锁逻辑驱动道口接近和到达条件,实现道口自动通知及道口自动信号,保证站内咽喉区道口行车安全。

Research on and Application of the Combination of Crossing in Throat Area with Computer-based Interlocking

With reference to engineering practices,this paper addresses some important issues related to approach notification time,approach notification position and crossing signal location and puts forward the proposal to combine the crossing signal in throat area with computer-based interlocking,the interface technical conditions and circuits.It also demonstrates the application of computer-based interlocking logic to activate crossing approach and arrival conditions to achieve auto crossing notification and control so as to protect the train running through crossings in station throat section.
