摘  要：如今，人民生活水准在逐步提高，生活方式在慢慢改变，传统的餐饮业也随之发生了天翻地覆的变化。在以往，餐厅的点单、送单以及结算等服务都是由人工来完成的，这种操作流程比较复杂，特别在用餐高峰期间，服务效率会显得比较低下，而且操作的失误率也会大大提升。随着无线通信技术的发展运用，把这种无线技术用于餐饮行业，不仅可以减少劳动力，还可以提高服务质量，让一切都变得有条不紊。

为了完善生活中这种点菜的不完美，本作品设计了一款点菜机，它主要包括STC89C52单片机模块、12864液晶显示模块、NRF24L01无线传输模块、电源模块等，从而实现无线点菜的功能。其中，STC89C52单片机是整个系统的核心，管理着12864液晶显示屏的各个功能界面以及NRF24L01无线传输模块数据的发送与接收。此设计实现了从点菜、运输以及结算全过程的自动化，方便了管理，提高了效率。

无线传输点菜系统的设计有利于餐饮管理系统朝着更加信息化、先进化、高效化的方向发展，具有很大的开发前景，值得人们去深究与探讨。

Intelligent wireless ordering machine based on 51 single chip microcomputer

Abstract：Nowadays, people's living standard is gradually improving, lifestyle is slowly changing, and traditional catering industry has changed dramatically. In the past, the service of the restaurant's order, delivery and settlement is done manually. This operation process is more complex, especially during the peak period of the meal, the efficiency of service will appear relatively low, and the error rate of operation will be greatly increased. With the development of the use of wireless communication technology, the wireless technology in the catering industry not only can reduce the labor force, but also can improve the quality of service so that everything becomes orderly.

In order to improve the imperfection of this kind of ordering in life, this work designed an ordering machine, which mainly includes STC89C52 MCU module, 12864 LCD module, NRF24L01 wireless transmission module, power module and so on, thus realizing the function of the wireless ordering. Among them, STC89C52 is the core of the whole system, which manages the functional interfaces of 12864 LCD screens and the data transmission and reception of the NRF24L01 wireless transmission module. This design realizes automation of the whole process from the ordering, transportation and settlement, which facilitates the management and improves the efficiency.

The design of the wireless ordering system is conducive to the advanced and efficient development of the catering management system. It has a great prospect of development. It is worth exploring and discussing the technique.

The thesis has 11 figures, 2 tables and 8 references.
