图形化仪表控制系统上位机软件的设计与开发

PC Software Design and Development of Graphical Instrument Control System

介绍了图形化仪表控制系统上位机软件的设计思想和开发过程,详细描述了可拖曳图形设计、图形编译为指令、指令反编译为图形等功能模块的设计,并说明了自定义指令协议的格式,以及该协议在整个软件中起到的沟通图形与指令的功能。着重解释了三层XML文件组成形式,展示了利用这种方式编译、存储用户图形操作结果的优势。该软件作为图形化工业仪表控制系统的上位机软件部分已基本完成了项目的要求。

This paper focuses on introducing design and development of PC software of graphical instrument control system, detailed describes designs of functional modules including draggable graphic design, graphic compilation of instructions, instruction decompile graphic and a custom command protocol format as well as its connection role for graphics and instructions. Meanwhile, it explains composition forms of three-levels XML, shows its advantages in compiling and storing operating results of user graphics. The software basically meet the requirements of project.
