摘要
为适应高速铁路、快速客运专线、铁路信号一体化的发展,计算机连锁控制系统作为车站关键基础信号设备,不仅要具有高度的安全性、可靠性、实时性、可维护性、可用性等基本特性,还应有强大、快速的处理能力,丰富、方便、安全的接口设备以及良好的可扩展性。本文介绍了满足这些要求的基于RTLinux/Linux的容错计算机连锁系统的软硬件体系结构,分析了其构成和特性,讨论了Linux操作系统实时性问题。
In order to adapt to the rapit development of high speed railways, express passenger special lines and rail signal integration, The Computer Interlocking Control system( which is a key railway station signaling equipment) must have the feature of high security, reliability, real - time, maintainability and usability and slso the features of strong and rapid processing and frinendly interfaces and good scalability. In this paper, we introduce the design and implement of Computer Interlocking Control System satisfying above request, analyse the structucre of system and discuss the problem in real - time on Linux.
