【摘要】 随着嵌入式系统技术的发展，以ARM公司的32位RISC处理器结合开源免费、性能优良的Linux操作系统的嵌入式平台，越来越受到嵌入式手持设备商的青睐，近年来，显现了巨大的市场价值和广阔的应用前景。论文研究和解决的重要课题是设计一个基于linux的嵌入式点菜系统终端系统。首先介绍了嵌入式系统的概念，基于linux作为嵌入式手持设备的操作系统的优点，并通过比较列举了基于linux嵌入式手持平台来开发点菜系统终端所具有的各种特点。然后，进行了硬件平台的设计，搭建软件开发平台。硬件平台主要有三大模块，分别为基于s3c2410处理器的核心板模块，基于RF905的无线收发模块，和基于LQ035Q7DB02、LZ9FC22和ADS7846的LCD触摸屏模块。再次，设计了linux下无线收发驱动程序，在pc机和嵌入式平台上建立了MiniGUI的开发平台，并基于对MiniGUI下IAL、GAL等引擎机制及移植相关源代码的分析，在本平台上移植了MiniGUI，建立了基于linux嵌入式手持设备。最后通过对酒店点菜系统终端的需求分析，进行了点菜系统的软件程序设计。采用了无线载波监听并设计了通信协议，实现了无线多对一通信。更多还原

【Abstract】 Along with the development of the technology of embedded system, the embedded platform combining the 32-bit RISC Processor of ARM Corporation with the free, source-open, well-performed Linux operating system , has been more and more favored by the embedded handset device manufacturers, and has recently displayed a significant market value and application prospect.This dissertation is about the design of a Linux-based embedded handset device of a food-ordering system terminal.ft first introduces the concept of embedded system, the merits of linux as the operating system for embedded handset devices, and then discusses the characteristics of an embedded linux handset device platform in developing a food-ordering system terminal.A handware platform is designed and a software development platform is established. The hardware platform consists mainly of three major modules: a core module with s3c2410 as the processor, a wireless correspondence module based on RF 905, and a LCD touching screen module based on LQ035Q7DB02. LZ9FC22 and ADS7846.Then, a Iinux-based wireless correspondence module is designed and a MiniGUI development platform is established on the PC machine and the embedded system. The engine mechanism of IAL and GAL of MiniGUI and the source codes for the translplantation of it are analyzed and MiniGUI is transplanted to establish the Linux-based embedded handset device.Finally, a food-ordering system software is designed on the basis of need analysis of the restaurant, food-ordering terminal system. Using of the listening to wireless carrier wave and de designing of communication protocol, the wireless communication of many-to-one is realized.更多还原
