Wireless Order Systems Design And Implement Based On S3C2440

With the development of technology and improvement of people living standard,the information management system is adopted gradually by the food and drinkindustry, a gold business in China. Actually, there are some drawbacks such as lowerefficiency, intensive labor and not enough consideration in heavy lunch time for thesewaiter or waitress. So after using wireless ordering system, these disadvantages maybe solved for managers. The efficiency and service can be improved. This paper showthe way of the ordering terminal based on an embedded equipment includingS3C2440.From the hardware point, the equipment which is choosed by this paper includedseveral types such as Nandflash, LCD and so on. On the other hand, there are threesections according to the whole project, consisting of operation system transplanting,Qt programming design and wireless network establishing. U-boot transplanting, filesystem founding and core transplanting belong to operation system transplantingsection.During OS transplant part, this paper shows the process of loading in detail.Consulting with the method of U-boot transplant in S3C2410CPU and differencebetween both, this paper demonstrates the steps of S3C2440CPU. In the yaffs sectionof paper, ways of building root file system by mkyaffs2image into model will bedescribed. The most important part of this paper is forth section about softwaredesigning consisting of demanding analyse, Qtopia setting up, communicationtechnique, NFS configuration and socket programming. In the last part, severalwireless network means will be studied. And Wifi technology will be used as amethod to install wireless network, including the way of configuration andconfiguration methods.At last, this paper analysis functions of wireless ordering system. Also it cannotbe avoided of some disadvantages in this system, which should be perfected in thefuture. And it is true that it will have a widespread applicate prospect. After using suchsystem, it is no deny that people working in the restaurants are going to feel relaxedeven in rush dinner hour.
