高铁列车运行控制信息传递流程结构脆性分析
Structural Brittleness Analysis of Information Transfer Process of High-speed Railway Train Control
摘要
Abstract
The majority of previous studies on train control process safety focused on individual subsystems;this approach lacks wholeness and ignores the risk-sharing problem introduced by information transfer between different subsystems.Here, a three-level system, namely a computerbased interlocking system, train control system, and centralized train control system, was modelled from the perspective of information passing between subsystems, and the structural brittleness of the train control process was analysed.First, the structural brittleness of the high-speed railway train control process was stated according to brittleness sources, the brittleness propagation path, and the system crash standard.Then, a simulation platform was set up for system brittleness analysis based on the I/O file stream in CPN Tools and C # programming language, and a simulation example was designed.The results show that the average correlation between sub-transitions in the movement authority request submodel is 56.72％, and that in the CTCS-3 submodel is 9.56％;these results provide a reference for the differentiated typical safety management strategy.关键词
