嵌入式装置可视化程序差异分析软件设计

Design of Visual Program Difference Analysis Software for Embedded Device

嵌入式装置程序采用可视化编程软件进行开发和调试。之前在工程升级维护过程中,缺乏可视化页面修改前后的差异分析描述方法,仅靠研发人员手工书写的变更说明来进行验证,往往存在漏改、错改等不一致的情况。设计了可视化工程的差异分析软件,可导入工程、装置、插件、元件、页面等不同层级的可视化程序,自动分析差异内容,支持展示页面对比视图,按照编辑类型显示差异项,点击差异项,定位两侧区域并高亮显示关联符号。软件支持将差异信息标注到可视化页面视图中,并将视图导出为PDF文档,自动形成变更对比说明文档,方便变更测试人员、审核人员和用户在没有可视化软件的情况下可阅读查看差异内容。开发的软件已经在华能水电工程中进行了应用,提升了工程升级的可靠性。

The embedded device is developed and debugged by visual programming software.In the process of engineering upgrade and maintenance,there was a lack of difference analysis and description methods for the modification of visual pages.Verification can only be carried out by manual change instructions written by the r&d personnel,and there were often inconsistencies such as omission,errors.This paper designs the difference analysis software of visual engineering.The software can import the project,device,board,component,page and other different levels of visual program,and then automatic analysis of different content.The software supports a comparison view of the presentation page,showing the difference items grouped by edit type.Click on the difference item to position both sides of the area and highlight the association symbol.The software supports annotating the difference information into a visual page view and exporting the view as a PDF document.The software can automatically form a change comparison document,making it convenient for change testers,reviewers and users to read and see the differences without visual software.The software developed in this paper has been applied in the project of Huaneng water electric,improving the reliability of project upgrade.
