基于龙芯的二乘二取二计算机联锁控制系统

铁路车站信号计算机联锁控制系统是一个实时、多任务、安全苛求的计算机控制系统。该系统以中国科学院计算机研究所研制的龙芯系列处理器为核心,使用开源的Linux操作系统,在保证系统的实时性、安全性、可靠性、可扩展性、多任务处理和节能环保的同时,也避免了在计算机联锁控制系统中使用国外的处理器可能存在的安全隐患。

Double 2-Vote-2 Computer Interlocking Control System Based on Loongson CPU

Railway station signal computer interlocking control system is a real-time, multi-task and safety-critical computer control system.The core of this system is the Loongson CPU developed by Institute of Computing Technology Chinese Academy of Sciences and the Kaiyuan Linux operation system. Ensuring traits such as the real-time, security, reliability, scalability, multi-task and energy-saving, at the same time, the system escapes the safety loophole of abroad processor in the computer interlocking control system.
