速度控制器图形化显示系统研究

Graphics Display System in Speed Controller

主要完成液体黏性调速控制器的液晶显示部分的设计,使控制系统具备较强的人机交互能力。在硬件方面,主要介绍处理器及显示部件的选型,显示系统硬件接口设计。在软件方面,详细介绍硬件驱动设计,以及友好窗体化用户界面设计。实践证明,LPC2220处理器结合基于T6963控制器的HF240128A2液晶模块为软件设计提供了一个良好的硬件平台,提高了系统的可开发性。而μC/OS及GUI先进软件技术的应用,使得软件结构变得更加清晰,并且大大降低了系统的开发难度。ARM7处理器、μC/OS操作系统、GUI等先进计算机技术集中应用于控制器的液晶显示系统,很好地解决了工控领域中普遍存在的人机对话界面单调、功能单一的问题。

The design of graphics display system was analyzed, which will enhance the man-machine interaction of speed controller. In hardware,it introduced the selection of CPU and LCM and the design of hardware interface. In software,it particularly introduced the design of driver and friendly UI. Practice has proved that LPC2220 processor combined with HF240128A2 provides a good hardware platform for software. The application of μC/OS and GUI makes software structure become more clear.
