【正文】 nd reassuring this paper,meidea, system architecture, and functions of a selfservicerestaurant 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 wireless 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 embedded Qt and Qtopia software have been developed in theembedded Linux operation system. Basing on the analysis of the server databasemodules, the functions of display menu, categories searching, orders, bil, and dataprinting have been realized. Compared with the existing handheld terminal。關(guān)鍵詞: PXA270。本設(shè)計與市場上現(xiàn)有的手持餐飲終端不同的是，對手持終端的功能進行了擴展，實現(xiàn)了手持終端Web服務(wù)器，廚師們即可通過訪問客戶手持終端的菜單來制作菜品。文章對手持終端的軟硬件環(huán)境進行了深入的探討，其中，硬件環(huán)境包括:PXA270 LCD顯示模塊、觸摸屏模塊、CF卡無線通信模塊等。摘 要如今，隨著科技的發(fā)展，餐飲企業(yè)依托科技的進步更全面、周到、便捷地為廣大消費者服務(wù)，同時實現(xiàn)企業(yè)自身的快速發(fā)展。軟件環(huán)境包括:荃于PXA270平臺的嵌入式linux操作系統(tǒng)移植、基于嵌入式Linux的Qt和Qtopia的相關(guān)軟件開發(fā)、基于Windows操作系統(tǒng)IIS服務(wù)點菜數(shù)據(jù)庫的開發(fā)、基于嵌入式Linux操作系統(tǒng)Web Server服務(wù)功能的軟件開發(fā)和Linux操作系統(tǒng)下Apache服務(wù)器端視頻監(jiān)控的功能開發(fā)。另外，本設(shè)計還開發(fā)了手持餐飲終端的遠程監(jiān)控功能，使顧客在用餐區(qū)也能看到廚房中菜品的現(xiàn)場制作過程，從而放心的用餐。 。market, the design is diferent of extend the functions including the web chef can cook by visiting customer39。 JPEG目 錄摘 要 ................................................................................................................................................IABSTRACT....................................................................................................................................II目 錄 .............................................................................................................................................III第 1 章 緒論 ...................................................................................................................................1 引言 ........................................................................................................................................1 本設(shè)計研究的背景和意義 ....................................................................................................1 論文實現(xiàn)的目標 ....................................................................................................................2第 2 章 自助式手持餐飲終端整體設(shè)計 .......................................................................................3 設(shè)計需求資源分析 ................................................................................................................3 自助式餐飲終端整體體系結(jié)構(gòu)設(shè)計 ....................................................................................3 自助式手持餐飲終端軟件結(jié)構(gòu)設(shè)計 ....................................................................................5第 3 章 自助式手持餐飲終端軟硬件環(huán)境的建立 .......................................................................7 硬件環(huán)境 ...............................................................................................................................7 軟件開發(fā)平臺的建立 ............................................................................................................7 嵌入式 Linux 操作系統(tǒng)的定制 ......................................................................................7 Qt/Embedded 及 Qtopla 桌面環(huán)境的建立 .....................................................................8 嵌入式 Konqueror 瀏覽器的分析 ..................................................................................8第 4 章 持餐飲終端與數(shù)據(jù)庫服務(wù)器的無線通信 .....................................................................11 概論 ......................................................................................................................................11 無線網(wǎng)卡的驅(qū)動分析和設(shè)計 ..............................................................................................11 PCMCIA 系統(tǒng)結(jié)構(gòu) .......................................................................................................11 Socket Driver 的實現(xiàn) ....................................................................................................12 PCMCIA 驅(qū)動的實現(xiàn) ...................................................................................................13 PCMCIA 接口 CF 卡的配置使用 ................................................................................14 數(shù)據(jù)庫服務(wù)器的建立 ..........................................................................................................15 數(shù)據(jù)庫服務(wù)器端整體功能分析 ...................................................................................15 前臺模塊設(shè)計 ...............................................................................................................16 后臺模塊設(shè)計 ...............................................................................................................19 自助式手持餐飲終端與系統(tǒng)數(shù)據(jù)庫服務(wù)器之間的通信 ....................
