摘　　要：针对列控系统传统建模方法存在的缺点,在对CTCS-3级列控车载设备进行需求分析、系统分析和对象分析的基础上,引入嵌入式系统的快速面向对象开发过程(ROPES)的建模方法。利用该方法进行CTCS-3级列控系统车载设备的体系架构设计,建立了系统的详细模型。利用Rhapsody工具,将模型转换成基于实时框架技术可执行的代码,自动生成测试案例,对模型进行验证。测试结果表明,该建模方法有效降低了软件设计的复杂度,缩短了车载设备软件的开发周期。To avoid the disadvantages of the traditional modeling methods in train operation control system,and based on the analyses in respect of the requirement,the system and the object of CTCS-3on-board equipment,the modeling method of Rapid Object-oriented Process for Embedded System（ROPES） was applied to CTCS-3 automation train protection system.With this method,the system structure of CTCS-3 on-board equipment was designed and a detailed model was established.By means of Rhapsody,the model was transformed to the executable code based on real-time framework technology,and the test case was generated automatically to validate the model.Simulation test results show that the modeling method can obviously reduce the complexity of software design and shorten the development cycle for onboard equipment software.
