基于嵌入式系统的家居能源控制子系统人机交互设计

Man-machine interface design of residential energy control system based on embedded system

随着测控对象的复杂化和测控功能的多样化,界面友好的人机交互接口设计在整个分布式测控系统中发挥了越来越重要的作用。基于对加拿大某公司家居生活能源系统中的控制子系统的研究,本文详细分析了用于该系统的液晶屏(LCD)和触摸屏的工作原理,设计了以S3C2410为硬件平台、Linux操作系统为软件平台的LCD驱动程序和触摸屏驱动程序以及基于Qt/E的图形用户界面。应用结果表明:整个人机交互接口操作方便,具有良好的稳定性、可靠性和扩展性,同时对嵌入式系统的研究有一定的参考意义。

With the complication of object and diversification of function, friendly man-machine interface plays a more and more important role in distributed measure and control system. Based on control system of one Canada residential energy system, this paper particularly analyzes the principles of LCD display and touch-screen and designs LCD driver and touch-screen driver based on s3c2410 and Linux operating system. This paper also includes how to design friendly user graphic interface with Qt/E. Application shows that this man-machine interface is convenient, stable, reliable and extensible. Meanwhile, it can be the reference of embedded system research.
