| 摘 要： | 既有线铁路系统运营场景复杂，运营需求多变，导致列车运行监控装置（LKJ）功能需求变化频繁，为了合理、规范地管理功能需求，有必要基于UML对LKJ功能进行建模研究。通过分析LKJ的结构与功能，建立了系统的用例模型；利用UML语言中的类图、顺序图和状态图，分析LKJ主要运营场景的静态结构与动态行为，并由此建立各场景的静态模型和动态模型；最终对所建LKJ功能模型进行验证，确保模型的正确性和完整性。利用所建的LKJ功能UML模型，能避免对LKJ功能需求的歧义理解，有利于开发与维护工作的顺利进行。

| Abstract: | Operation environment of existing railway system is complicated, the operation demands is changeable, which result in the function requirement of train operation control and monitoring device(LKJ) change frequently. In order to manage the requirement properly and regularly, it is necessary to model the function of LKJ based on UML. This article analyzed the structure and function of LKJ, created use case model of system; by using class diagram, sequence diagram and state diagram in UML, analyzed the static structure and dynamic behavior for main operation scene of LKJ, established static model and dynamic model; verified the accuracy and completeness of the LKJ function model. By usin the LKJ function model, people can avoid the ambiguity of the LKJ functional requirements, which is conducive to the smooth development and maintenance. |
