 摘 要
     
 随着信息技术日新月异的发展，嵌入式系统在信息终端上的应用越来越广泛。由于嵌入式系统在硬件方面的限制，需要GUI平台具有短小精悍、可靠稳定、方便移植、可裁减等特性，因此需要一个轻量级的通用图形用户接口，提供给终端的用户使用，从而加速终端设备的普及和发展。因为MiniGUI具有轻型，占用资源少，高性能，高可靠性等特点，所以MiniGUI能够好的提供一个满足需要的开发基础平台。与此同时，随着家用电器的增多，使得人们需要一个方便的智能终端进行统一操控。本论文研究在嵌入式Linux下基于MiniGUI开发一个智能家居信息终端。
 本论文详细介绍了整个系统的开发过程，从交叉编译开发环境的搭建，MiniGUI库和资源文件的移植，ramdisk.gz制作，到Flash的烧制以及终端图形化界面的设计与实现。
 系统实现采用JXARM9-2410嵌入式开发板作硬件平台，在Linux操作系统下利用MiniGUI作为图形用户界面软件开发平台，实现智能家居系统的主界面显示、智能家居系统开关控制显示、智能家居系统定时控制显示等功能。最后，本文对智能家居终端开发进行了总结，并对需要进一步解决的问题进行了讨论。

MiniGUI –Based Embedded Linux
Information Terminal Software Development
 
 ABSTRACT
 With the rapid development of information technology, the embedded system is more and more frequently used in information terminal. Because the embedded system has some limitations on hardware, its GUI platform should be short and pithy, reliable and steady, convenient to transplant and able to reduce, thus it needs a lightweight common graphical user interface to be provided for the terminal user. The need accelerates the popularization and development of the terminal appliance. MiniGUI have these advantages, such as take up fewer resources, high performance, high reliability, etc. So can MiniGUI meet the needs of the development platform. Meanwhile, with the increase in household appliances, we need to make an intelligent terminal for the unified control. This paper introduces with detail an information terminal software-brainpower household system which is developed on the base embedded Linux and MiniGUI.
 This paper introduces the development process of the system, the development environment’s construction of cross translation, the transplant of MiniGUI storeroom and resource, the fire of Flash, the design and realization of terminal graphical user interface.
 In practice, the paper adopts JXARM9-2410 embedded development board as software platform, and it also takes MiniGUI which belongs to Linux operating system as software development platform of graphical user interface, which, aims at realizing the functions of display the main interface, switch control and timing control of the brainpower household system.In the end, the paper summarizes the development of the brainpower household terminal and discusses problems which need to be solved in implementations.
