基于通信方式实现的超大规模站场联锁系统解决方案

Solution of Interlock System Based on Communication for Very-large-scale Station Yard

为满足超大规模站场联锁系统控制,提出了分由2套计算机联锁系统控制一个车站的方案,2套计算机联锁系统之间通过通信的方式传递2套联锁系统分割处的联锁逻辑条件。从系统结构以及需要修改的通信软件方面,分析了怎样安全传输分割控制处的联锁逻辑条件,经工程实践证明是一个十分可靠的超大规模站场计算机联锁系统解决方案。

In order to meet the control field in large scale station interlocking system, we put forward a solution of using two sets of computer based interlocking system to control one station. Interlocking logic conditions between the two sets of computer interlocking system are transferred through communication. We describe the structure of the system and the communication software needed modifying, and analyze how to the transmit the interlocking logic conditions in a safe manner. It has been verified that the solu- tion is reliable to large scale station computer interlocking system in practice.
