基于ZigBee技术的无线点菜系统设计

Design of wireless dishes ordering system based on ZigBee technology

为了提高餐厅的工作效率,实现信息化管理,设计了一种利用TI公司CC2530芯片的基于ZigBee技术的无线智能点菜系统。该系统采用4×5矩阵键盘采集点菜信息,在点菜终端和管理中心构建ZigBee无线通信网络,将点菜信息通过无线网络发送到收银台及厨房供收银及烹饪使用。给出了从客人开台到结账的一整套详细方案及具体实现过程,分析了系统的工作原理、硬件组成、软件设计。实验结果表明误包率在40m范围内可控制在2.4%以下。该系统具有数据传输误包率低、稳定可靠、操作简单和成本低等优点。提高了餐厅信息化管理水平,缓解了不断增长的客流与餐厅工作人员不足的矛盾。

In order to improve the efficiency of the restaurant,and achieve information management, a wireless dishes ordering system which is based on ZigBee technology and use a CC2530 chip of Texas Instruments Company is designed. The system uses 4× 5 matrix keyboard to collect order information, builds ZigBee wireless communications network between order terminal and management center, and sends order information to cashier and kitchen by wireless network. This paper gives a detailed scheme and implementation process from the guests start to ordering to checkout, the paper also analysis and design the method of hardware and the software process for the system detailed. The result of experiment shows that the packet error rate can be controlled less then 2.4 % When the distance is less than 40 m. The system has many merits including low data transform Packet error rate, reliable, easy operation and low cost etc. The system advances restaurant information management level and improves the contradiction between the growing traffic to restaurant and the lack of staff.
