基于Qt的粮情测控系统GUI设计

GUI design of grain monitoring and control system based on Qt

针对传统图形界面占用空间大、可配置性差、实时性不强等问题,在对粮情测控系统的GUI(图形用户界面)设计中,提出了一种基于Qt/Embedded的图形库构建方法。采用S3C2440为硬件平台,并移植了可裁剪的嵌入式Linux系统。开发了针对触摸屏的设备驱动程序和图形界面接口。完成了数据采集、信息处理、监控管理的任务,适应了现代粮情测控技术的应用需求。现场试验表明,该系统具有界面友好、操作方便、易于维护等特点。

Aiming at problems of Grain Monitoring and Control System （GMCS） GUI （Graphical user interfous）such as large occupation space, poor configuration ability and low real-time performance, a kind of embedded components library realization method based on Qt/E was brought forward. The hardware platform based 6n S3C2440 was used and the embedded Linux was transplanted, the necessary device drivers for touch-screen and graphical interfaces were designed. It completed the data acquisition, information processing, monitoring and management, in order to meet the modern GMCS applications need. The experimental results show that it is user-friendly, easy operation and maintenance.
