摘要
针对铁路车站联锁系统需测控的点多,测控对象地理分布范围广的特点,提出了一种基于P rofibus现场总线的计算机联锁控制系统,从硬件系统和软件系统两方面进行了的阐述。着重介绍了双机热备份二模动态切换技术的实现机制。
The paper comes up with a computer interlocking system based on ProfiBus field bus in accordance with the fact that there are a number of monitoring and control points in railway interlocking system, and that monitoring and control objects are widespread. It expounds the system in hardware and software, and especially expatiates on the achievement mechanism of double hot backup machine and dynamic switch technology over two modules.
