| 摘 要： | 高速铁路列控系统中C3单元和C2单元相对独立控车,两套系统中的列控数据在系统层之间缺乏共享和约束机制.本文在分析系统结构和数据传输特性的基础上,提出一种基于数据融合,提升高速铁路临时限速安全性的方案,并利用有色Petri网（CPN）对融合方案进行建模.通过仿真软件分层和赋时功能构造系统顶层模型、临时限速生成子模型、故障子模型、融合子模型和时间序列,模拟临时限速信息传输过程中的系统状态和行为.仿真结果表明：在故障注入情况下,数据融合方案在一定程度降低了错误数据的输出,提高了系统的安全性.

| Abstract: | Because of high-speed railway control system has C2 part and C3 part work independently, and there is lack of communication and restriction mechanism between the two parts in system layer. This paper proposes the fusion method of TSR based on data fusion by analyzing train control data and system structure, and applies CPN to model and verifies this method. It creates system top-level model, TSR sub model, fault sub model, data fusion sub model and time series by using the function of hi- erarchy and timing. And it simulates the system states and behaviors in the transmission process of TSR. The simulation results show that data fusion method can reduce the fault data output quantity to some extent, so it will improve the safety of system. |
