【摘要】：餐飲行業(yè)實行信息化管理的一個重要組成部分是無線電子點菜系統(tǒng)，該系統(tǒng)的廣泛應(yīng)用在給餐飲企業(yè)帶來良好的經(jīng)濟效益的同時也大大推進(jìn)了先進(jìn)的信息技術(shù)在國民經(jīng)濟中的推廣應(yīng)用，產(chǎn)生一定的社會效益。目前國內(nèi)電子點菜系統(tǒng)大多屬于高、低檔產(chǎn)品，，由于不適合中國國情的中檔消費需求而導(dǎo)致推廣速度十分緩慢。本文通過分析比較國內(nèi)市場較常見的幾種電子點菜系統(tǒng)的優(yōu)缺點，指出這些點菜系統(tǒng)的區(qū)別主要在于點菜終端和通訊方式的選擇上，基于這種考慮提出并設(shè)計了一種適合中國國情的中檔無線電子點菜終端解決方案：利用嵌入式系統(tǒng)開發(fā)無線點菜終端，運用短距離無線通信技術(shù)和長距離無線通信技術(shù)相結(jié)合進(jìn)行數(shù)據(jù)傳輸。 文章首先對無線點菜系統(tǒng)的組成及功能分配進(jìn)行了介紹，并在此基礎(chǔ)上設(shè)計了系統(tǒng)的各個硬件模塊。接著對觸摸屏數(shù)據(jù)采集的全過程進(jìn)行了分析，并探討了影響觸摸屏數(shù)據(jù)定位精度的各種因素。然后文章綜合分析比較了幾種常用的小范圍無線通訊方式，最終確定采用SRWF-501無線射頻收發(fā)器件實現(xiàn)短距離無線通訊，采用GPRS無線技術(shù)實現(xiàn)遠(yuǎn)距離無線訂餐，并設(shè)計了一種具體的數(shù)據(jù)幀格式和分層通訊協(xié)議，通訊系統(tǒng)的模型采用主站論詢，而從站監(jiān)聽的方式。文章最后開發(fā)了整個系統(tǒng)的軟件模塊，首先研究了BootLoader啟動代碼的設(shè)計和UC/OS-II操作系統(tǒng)的在S3C44B0X上的移植，并成功將其下載到S3C44B0X中，然后在此操作系統(tǒng)的基礎(chǔ)上結(jié)合MiniGUI界面開發(fā)技術(shù)進(jìn)行了點菜界面、通訊協(xié)議及關(guān)鍵驅(qū)動程序的設(shè)計。 利用嵌入式UC/OS-II操作系統(tǒng)開發(fā)無線點菜終端，對此本設(shè)計具有一定的借鑒指導(dǎo)意義，對自助式餐飲服務(wù)業(yè)具有一定的商業(yè)實用價值。同時，作為一款便攜式手持產(chǎn)品，可以隨身攜帶，可以支持多種無線上網(wǎng)的場合，具有一定的市場應(yīng)用前景和商業(yè)實用價值。
[Abstract]:An important component of information management in the catering industry is the wireless electronic ordering system. The wide application of the system not only brings good economic benefits to the catering enterprises, but also promotes the application of advanced information technology in the national economy and produces certain social benefits. At present, the domestic electronic ordering system mostly belongs to the high and low grade products, which is not suitable for the middle range consumption demand of the national conditions of China, which results in the slow speed of popularization. By analyzing and comparing the advantages and disadvantages of several electronic ordering systems in the domestic market, this paper points out that the differences of these ordering systems mainly lie in the choice of ordering terminals and communication modes. Based on this consideration, this paper proposes and designs a kind of mid-range wireless electronic ordering terminal solution suitable for China's national conditions: developing wireless ordering terminal with embedded system. The short-range wireless communication technology and long-distance wireless communication technology are combined to carry out data transmission. Firstly, the composition and function distribution of wireless ordering system are introduced, and each hardware module of the system is designed. Then, the whole process of touch screen data acquisition is analyzed, and various factors influencing the precision of touch screen data location are discussed. Then this paper analyzes and compares several commonly used wireless communication methods, and finally determines to use SRWF-501 radio frequency transceiver to realize short range wireless communication, and GPRS wireless technology to realize long distance wireless meal reservation. A specific data frame format and hierarchical communication protocol are designed. The model of communication system is based on master station inquiry and slave station listening. Finally, the software module of the whole system is developed. Firstly, the design of BootLoader startup code and the porting of UC/OS-II operating system on S3C44B0X are studied, and it is downloaded to S3C44B0X successfully. On the basis of the operating system, the paper designs the order interface, communication protocol and key driver based on the MiniGUI interface development technology. The development of wireless ordering terminal using embedded UC/OS-II operating system has certain reference significance to this design and has certain commercial practical value to the self-service catering service. At the same time, as a portable handheld product, can be carried around, can support a variety of wireless Internet occasions, with a certain market application prospects and commercial practical value.
