基于安全通信实现区间方向控制在宜万线联锁工程的应用

Implementation of Section Direction Control in CBI Project of Yichang-Wanzhou Line Based on Safety Communication

计算机联锁系统在实现自动闭塞方向控制中目前大多采用的是与继电联锁的方向控制电路结合方式,自动闭塞电路仍保留四线制方向电路。由于计算机联锁系统实现自动闭塞方向电路的技术已经成熟,在此背景下宜万线采用计算机联锁实现自动闭塞方向电路控制。

At present, the method of combining the computer-based interlocking system（CBI） and relaybased interlocking system to fulfi ll automatic block direction control is used mostly and the automatic block circuit maintains the four-line directional circuit. With the technique of implementing automatic block direction circuit only by CBI system becoming mature, CBI system is adopted to fulfi ll the automatic block direction circuit control in Yichang-Wanzhow railway line.
