基于UML的AMT系统建模与实现
基于UML的AMT系统建模与实现 摘要
基于UML的嵌入式实时软件开发技术和开发环境是当今嵌入式实时领域 研究的一个热点。基于UML的嵌入式软件开发需要把现有的面向对象开发技 术和UML的使用经验,如可视化、模型的执行、模型的代码自动生成、框架 开发方法等与嵌入式实时系统的特点结合起来。本文阐述使用UML建模技术 对机械自动变速器(AMT)软件系统的建模和实现。
本文介绍了选题背景,国内外自动变速器的发展与趋势,传统嵌入式软件
开发的一般过程,UML技术在嵌入式系统开发中的优势。概要描述了AMT系 统的总体架构和工作原理,在系统设计和开发中需要注意的重点和难点问题。 还介绍了UML基本原理和设计技术,常用的UML开发工具Rational Rose的 特点和集成环境。在此基础上,利用UML工具进行了系统建模,并针对汽车 启动过程中离合器的控制和换档策略进行了详细分析,使用C语言进行编程, 并列出了部分源代码,对实验结果进行了分析。采用UML建模可以降低系统 开发的复杂性,缩短开发周期,提高开发效率,易于维护和升级。本文最后介 绍了在本系统的设计和开发过程中所采用的配置管理技术,利用它可以协同开 发更加有效。

Modeling and Implementation of AMT System
Based on UML
ABSTRACT
The approach to real-time software development and its environment based on眦is
important aspect of embedded real-time field.It is necessary to combine Object·Oriented and UML
technologies,such鹳visual modeling,executable model,automatically generate code,丘mn即毗
etc..而廿l the special feature of embedded real-time for developing the embedded real-time software. This thesis ill仃oduces modeling and implementation ofAutomated Mechanical Transmission(AMT)
system based UML.
This thesis introduces the background of the theme,the development and the trend of
Automated Transmission(AT)in world-wide,general procedure of traditional embedded system
development,and the advantages using UML techniques.The construction and principle of AMT system introduced;some important problems of AMT system discussed.The basic principle and technologies of design about UML ale introduced,features and integrity development environment of typically UML development tool,Rational Rose explained.On the basic of that, all kinds ofmodel related to the system ale implemented,coupled with the detail analysis about the
control of clutch during setup of the vehicle and the shift strategy,programming by C language, parts of codes listed,the results of the experiment黜analyzed.With the help of UML modeling,system complex is reduced,development cycle is shorted,the cost is saved,maintaina
