摘要
分析了基于通信的列车控制系统(CBTC)ATP防护模型和列车在移动闭塞下追踪运行模型,给出了防护曲线算法;根据ATP系统构成建立仿真数据库模型;根据超速防护算法的迭代性设计仿真步长;针对仿真系统实时性需求采用多线程响应方式进行数据交互。运行结果证明了仿真的准确性。
The automatic train protection model based on CBTC and the running model in moving block system are analyzed and an algorithm Of protection curve is proposed. According to the constitution of the ATP system, a conceptual data model is built. Due to the iterative property of the algorithm, the simula- tion step is concluded. To enhance the real-time response, the simulation system adopts a multithreading solution in database application. Finally, the simulation results show the accuracy of the simulation sys- tem.
