基于RFID的智能点菜系统的设计与实现

Design and Implementation of Intelligent Ordering System Based on RFID

在分析无线餐饮点菜设备发展的基础上,针对现有无线点餐设备无法实现无服务员点菜的智能化服务的问题,提出一种基于RFID的智能点菜系统的解决方案。该方案将点菜器嵌入餐桌中,顾客可在无服务员的情况下自行完成点餐。此点菜系统由硬件部分和软件部分组成,其中,硬件电路中读菜器的控制部分选用功能强大的ARM S3C6410芯片;软件方面编程实现了点菜器与读菜器间的射频通信,上位机端菜单分页显示等功能。同时,创造性地提出了针对该系统的防碰撞算法和顾客等待时间估算算法。实验证明,提出的基于RFID的解决方案具有成本低、系统稳定可靠、架构简单,智能化程度高等优点,是一种较为理想的适合大中型餐饮地点的点菜系统。

Abstract： Basing on the analysis of wireless dining equipment development which can not achieve dining without a waiter, we propose a scheme which is based on the RFID （Radio Frequency Identification Devices ） intelligent ordering system scheme. This scheme is compose of hardware and software in which the powerfull ARM S3C6410 chip is used in our reading device; and we has programmed the RF communication between our la carte device and reading device, the classification of menu showing on PC, etc. Meanwhile, an anti-collision algorithm and a customer waiting time evaluating algorithm are proposed creatively. The experiment proves that this RFID solution owns the advantages of low cost, stable and reliable system, simple structure, high intelligent, etc, and it is an ideal ordering system for the large and medium-sized restaurants.
