摘　　要：针对高速列车控制系统的混成特性,提出了基于混成统一化建模语言的列控系统形式化建模和分析方法。运用UML2.0及其扩展机制对列控系统的混成行为进行建模。定义由HUML模型到HYTECH模型的转换规则,将HUML模型转换为线性混成自动机模型;将列控系统安全性需求加入到HYTECH模型,建立安全HYTECH模;利用模型检验工具HYTECH对安全HYTECH模型进行自动分析。根据所提出的基于UML概要文件建模方法,以移动闭塞系统中的追踪模型为例,建立后行列车的控制器HUML模型;通过计算安全HYTECH模型的可达集得到未知控制参数的取值范围;验证结果表明基于HUML的列控系统建模和分析方法的有效性。In view of the hybrid characteristics of high speed train control system, a formal modeling and parameter analysis method was proposed based on Hybrid Unified Modeling Language. UML 2.0 and its extensibility mechanism were used tomodel the hybrid behaviors of the train control system. The transformation rules from HUML model to HYTECH model were defined so as to convert HUML model into linear hybrid automata （LHA ）. Safety requirements of train control system were added into the established HYTEder to set up safety HYTECH model. Then,the safety HYTECH models were automatically analyzed by a model checking tool HYTECH . In the light of the proposed modeling method based on UML Profile, the tracking model of “Moving Block System” was taken as the case study and HUML controller model for followingtrain was set up. The corresponding value range of unknown control parameters was obtained through the cal-culation of the reachable set of safety HYTECH model. The verification results showed the effectiveness of HUML based train control system modeling and analysis method.
