摘要
介绍时速160 km以下,即CTCS-0、CTCS-1级自动闭塞系统的电子化研究与实现。系统主机采用二乘二取二计算机平台搭载VxWorks实时操作系统,保障系统的实时性和安全性;全电子执行模块用于现场设备的驱动和数据采集。区间控制软件采用模块化设计,以闭塞分区为单位可以根据不同的区间灵活组合。系统在硬件和软件设计上都遵循故障-安全原则。经测试,系统安全、可靠,可以在现场试点使用。
Aimed at studying and implementing electronic automatic block of CTCS-0 and CTCS-1 with train running speed of less than 160 km/h,the host machine adopts VxWorks real-time operating system via a 2-vote-2 computer platform to ensure the realtime-ness and safety.All-electronic execution units are used for driving and acquiring the data from field devices.Section control software was developed based on modularization design and could be built up according to different block sections flexibly on the base of block units.Both the hardware and software were designed in accordance with fail-safe principles.The testing results showed that the system is safe and reliable and can be used in pilot projects on the spot.
