发布时间：2018-11-02 16:25
【摘要】：餐饮行业实行信息化管理的一个重要组成部分是无线电子点菜系统，该系统的广泛应用在给餐饮企业带来良好的经济效益的同时也大大推进了先进的信息技术在国民经济中的推广应用，产生一定的社会效益。目前国内电子点菜系统大多属于高、低档产品，，由于不适合中国国情的中档消费需求而导致推广速度十分缓慢。本文通过分析比较国内市场较常见的几种电子点菜系统的优缺点，指出这些点菜系统的区别主要在于点菜终端和通讯方式的选择上，基于这种考虑提出并设计了一种适合中国国情的中档无线电子点菜终端解决方案：利用嵌入式系统开发无线点菜终端，运用短距离无线通信技术和长距离无线通信技术相结合进行数据传输。 文章首先对无线点菜系统的组成及功能分配进行了介绍，并在此基础上设计了系统的各个硬件模块。接着对触摸屏数据采集的全过程进行了分析，并探讨了影响触摸屏数据定位精度的各种因素。然后文章综合分析比较了几种常用的小范围无线通讯方式，最终确定采用SRWF-501无线射频收发器件实现短距离无线通讯，采用GPRS无线技术实现远距离无线订餐，并设计了一种具体的数据帧格式和分层通讯协议，通讯系统的模型采用主站论询，而从站监听的方式。文章最后开发了整个系统的软件模块，首先研究了BootLoader启动代码的设计和UC/OS-II操作系统的在S3C44B0X上的移植，并成功将其下载到S3C44B0X中，然后在此操作系统的基础上结合MiniGUI界面开发技术进行了点菜界面、通讯协议及关键驱动程序的设计。 利用嵌入式UC/OS-II操作系统开发无线点菜终端，对此本设计具有一定的借鉴指导意义，对自助式餐饮服务业具有一定的商业实用价值。同时，作为一款便携式手持产品，可以随身携带，可以支持多种无线上网的场合，具有一定的市场应用前景和商业实用价值。
[Abstract]: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.
