摘要 从硬件和软件两个方面研究并改进了现有的列车运行控制系统安全计算机平台,提出了一种简化型通用安全计算机平台.在不改变列控系统逻辑结构的基础上将独立的子系统集成到一台安全计算机上.然后对硬件结构的安全性指标和软件的时间、空间(内存)进行了仿真与计算,最终通过实验验证了通用型安全计算机平台的功能与性能,说明了该平台的正确性和有效性. The current safety computer platforms of train operation control system were studied in the aspects of both hardware and software,and a simplified general safety computer platform was put forward.The independent subsystem function was integrated on a safety computer without changing the train control system logic structure.Then,the safety indexes of hardware structure,time and space parameters of software were obtained by simulation and calculation.Finally,the function and performance of the general safety computer were verified by experiment,which proved its correctness.
