客运专线计算机联锁系统设计方案

Passenger Computer Interlocking System Design

由于客运专线列车运行速度较高,则要求作为重要安全系统的车站联锁设备具有较高的安全性和可靠性,由于速度的提高,系统处理的信息量也大量增加。传统的继电器集中联锁具有一定的局限,因此在客运专线联锁系统制式选择中不予考虑。而随着容错技术的发展,选择了高可靠性的专用安全型计算机系统。现有双机热备、三取二、二乘二取二等高级别冗余。本文重点对二乘二取二制式提出了两种设计方案进行研究,对第二种方案进行了深入的分析,表明更适合客运专线运营对可靠性和安全性的需求。

Passenger train speeds as high as an important safety system requiring the station interlocking device has a high safety and reliability,as speeds increase,the system also increased the amount of information processing.Traditional relay interlocking has certain limitations,so the standard Passenger selection interlock system shall not be considered.With the development of fault-tolerant technology,the type of high reliability for the safety of the computer system was chosen.This paper focuses on two squares to take two standard proposes two design study,conducted in-depth program on the second analysis,which is more suitable for passenger railway on reliability and security requirements.
