基于UML的需求分析方法在电力遥测信息系统中的应用

Application of Requirements Analysis Based on UML Object-oriented in Electrical-Telemetry System

文中介绍了基于UML面向对象的需求分析方法在电力遥测信息系统中的应用,针对电力遥测系统功能行为描述不清、在遥测需求变化时,不能及时响应和追踪等问题,采用原型法、螺旋模型和嵌入式系统快速面向对象过程模型相结合的需求分析方法,使用了UML统一建模语言,创建了用例图、活动图和状态转换图,使用户操作流程、系统子功能模块以及设备节点的信息视图化,提高了系统分析效率。在需求分析阶段使用概念测试,总结出了概念测试用例,有利于及时发现和纠正需求定义中的错误,减少了后期需求变更的维护成本。基于UML的需求分析方法最终生成了需求规格说明书,建立了需求基线,为项目系统的设计奠定了基础。

This paper introduces the application of the demand analysis method based on UML object oriented in the power telemetry information system.Aiming at the problems of unclear description of the function and behavior of the power telemetry system,and the inability to respond and track in time when the telemetry demand changes,the prototype method is adopted.The requirement analysis method combining the spiral model and the fast object oriented process model of the embedded system uses the UML Unified Modeling Language to create use case diagrams,activity diagrams and state transition diagrams,which enables the user’s operation process,system sub-function modules and equipment nodes to The information is viewed and the system analysis efficiency is improved.The concept test is used in the requirement ana-lysis stage,and the concept test cases are summarized,which is conducive to the timely discovery and correction of errors in the requirement definition,and reduces the maintenance cost of later requirement changes.The requirements analysis method based on UML finally generates the requirements specification,establishes the requirements baseline,and lays the foundation for the design of the project system.
