如今,随着科技的发展,餐饮企业依托科技的进步更全面、周到、便捷地为广大消费者服务,同时实现企业自身的快速发展。自助式手持餐饮终端就是在科技进步的大背景下产生并迅速发展起来的,其利用先进的无线通信技术、嵌入式手持终端技术、嵌入式移动数据库和远程监控等技术,满足了广大顾客方便、自主、放心的用餐需求。本文提出了自助式手持餐饮终端的设计理念、体系结构,同时设计了更具人性化的功能模块。文章对手持终端的软硬件环境进行了深入的探讨,其中,硬件环境包括:PXA270 LCD显示模块、触摸屏模块、CF卡无线通信模块等;软件环境包括:荃于PXA270平台的嵌入式linux操作系统移植、基于嵌入式Linux的Qt和Qtopia的相关软件开发、基于Windows操作系统IIS服务点菜数据库的开发、基于嵌入式Linux操作系统Web Server服务功能的软件开发和Linux操作系统下Apache服务器端视频监控的功能开发。在软件具体开发中,首先将嵌入式Linux操作系统移植到PXA270开发板上;然后基于嵌入式Linux操作系统,进行嵌入式Qt以及Qtopia图形界面移植:对服务器端数据库进行模块化设计,并具体实现菜单显示、分类查询、点菜、帐单显示及数据打印等功能。本设计与市场上现有的手持餐饮终端不同的是,对手持终端的功能进行了扩展,实现了手持终端Web服务器,厨师们即可通过访问客户手持终端的菜单来制作菜品。另外,本设计还开发了手持餐饮终端的远程监控功能,使顾客在用餐区也能看到厨房中菜品的现场制作过程,从而放心的用餐。本设计对基于嵌入式Linux操作系统进行终端开发,具有一定的借鉴指导意义,对自助式餐饮业具有商业实用价值。同时,作为一款手持式产品,可以随身携带,可以使用于多种支持无线上网的场合,具有一定的市场应用前景和商业实用价值。

Abstract
With the science and technology developed, nowadays, the food and beverageindustry facilitate the customer and promote the enterprise depending on theachievement of science and technology. Dining terminal has been developed in thisbackground, which use advanced munications technology, embeddedhandheld terminal technology, embedded mobile database, and remote moniteringand controling technology. That makes the customer more convenient,self-determined and reassuring this paper,meidea, system architecture, and functions of a self-servicerestaurant terminal has been put forward. The hardware and software environmentof the handheld terminal are deeply discussed: the hardware includes PXA270LCD display module, Touchscreen module, CF card municationsmodule, etc. and the software includes the transplantion of the embedded Linuxoperating system on PXA270 platform, the transplantion of the Qt and Qtopia inembedded Linux, the development of database in IS of Windows, the developmentof the functions software of Web Server and monitoring and controling of , embedded Linux operating system has been transplanted to PXA270board. Second, the e
