Abstract


Traditionally ordering in a restaurant, send a single, checkout manual transmission methods are used, this workflow is not only inefficient, but also in the dining peak, often due to service personnel quickly send handwritten ordering and artificial single and lead to many false operation, resulting in customer complaints, which not only affects the quality of service, but also damaged the restaurant's reputation. In order to change the traditional ordering patterns, the paper with embedded technology and wireless networking technology to develop a modern food service management system - wireless self-ordering system. Its work processes are briefly described below: Customer with handheld terminals on which to achieve self-ordering, and then through a wireless way to the menu point submitted to the server, the server management software ordering system menu and quickly accept customer returns accepted results and then the menu is displayed on the display to the kitchen, the chef is prepared according to the contents of the display menu, and finally run out of meal until the checkout customers, etc., consume content from the server system management software record keeping. In addition to providing a la carte handheld terminal function also provides multimedia entertainment function, support play multiple formats of audio and video files, so that customers are waiting for the meal of the time you can experience wireless ordering machine to bring the fun multimedia features, extended large-capacity memory interface can be connected to the external memory. Such a flexible, efficient, innovative information management system not only can improve the quality and efficiency of restaurant service, but because of the way customer self-ordering and reduce the human cost of the restaurant, bring economic benefits to the enterprise. This network of catering management system in recent years gradually been widely used. Generally speaking, wireless self-ordering system is to improve food service management and customization of the software and hardware systems. By the handheld terminal and the server through wireless communication to replace the traditional paper records and human way of working to provide customers with dining services. System hardware including service center server (PC), handheld wireless terminals, wireless network access point AP (wireless router), etc., which is wireless ordering system to provide basic device support. System software running on the server side, including management software and runs on handheld terminals la carte software. To set up a wireless router as the center of WiFi wireless local area network to provide a communication channel data transmission, data transmission operates 2.4GHZ ISM band. Wherein the server-side way to access a wired network, and terminal places wirelessly access the network. How effective and rational design of hardware and software to enable the wireless ordering system to achieve data transmission stability, reliability, security has become the focus of this thesis. System is based on Samsung S3C2440A ARM9 development board and with a 3.5-inch touch screen to simulate the hand-held terminal, using the VIA VT6656 controller chip wireless USB network wireless access module as a terminal to a PC as a server ordering system, and finally using TP -LINK TL-WR340G as a wireless access point (AP). By combining network programming, database programming, HMI and multimedia programming technology developed with the terminal server application software, the ultimate success of the simulation to achieve a set of wireless self-ordering system.
