基于嵌入式GUI的电力自动化设备人机界面设计

Human-machine interface design based on embedded GUI for power automation equipment

将嵌入式图形用户界面GUI(GraphicalUserInterface)技术引入到电力自动化设备的人机界面设计中。分析了嵌入式GUI的技术特点和体系结构(包括配置、核心、色彩管理、字体、内存设备、图形保真控件、驱动等模块),论述了采用这种技术的必要性与可行性,并以μC/GUI为例,详细介绍了开发原理、步骤和方法,指出了开发过程中需要注意的一些问题。采用嵌入式GUI进行人机界面设计后能够提高设备开发效率、节省维护成本、丰富人机交互信息。

The embedded GUI(Graphical User Interface) is introduced to the design of HMI(Human-Machine Interface) for power system automation equipment. Its technical features and ar-chitecture are analyzed,including modes of configuration,core,color,font,memory device,antialiasing,windows manager,widget and driver. The necessity and feasibility of its application are discussed. With μC / GUI as an example,the design theory,steps and method are introduced in detail and the key points in development are explained. The HMI design with embedded GUI increases develop-ment efficiency,lowers maintenance cost and enriches HMI information.
