无线点菜系统的设计与实现

介绍了一种新型无线点菜系统。给出了从点菜到菜单打印以及建立后台数据库对菜单进行管理等一整套详细方案及具体实现过程．该系统由无线点菜器和接收器端2部分组成，两者之间由无线数传模块实现数据的无线传输，可实现无纸点菜，以及菜单打印和对菜品的管理．系统采用单片机AT89S52作为点菜器的控制芯片，4×4矩阵式键盘键入桌号、菜号等数据，用OCMJ4X8C液晶显示器进行显示．接收端部分通过无线数传模块无线接收点菜器发来的菜单数据，然后送人数据库进行存储，管理者通过软件操作实现菜单管理并进行菜单打印．本系统稳定可靠，有很强的实用性．

Design and Achievement of Wireless Dish-Order System

The paper introduces a new wireless dish-order system and provides the whole project and the achievement process including ordering dishes, printing menus and constituting the database to manage the menu and so on. The system includes the dish-order instrument and the receiving part which are connected by the wireless data module, could achieve dish-order without paper and manage the menu. The system uses the MCS AT89S52 as the controlling chip of the dish-order instrument, the 4 × 4 matrix type keyboard to realize data input that includes the number of the table and the dishes, and the OCMJ4X8C LCD to display. Through wireless data module the receiving part receives data what is transmitted by the dish-order appliance and storages in database. The handlers could manage menu and print it by the software. The system is stable and dependable with great usefulness.
