基于RFID的餐盘自动结算系统

如今全国各大企业与各大高校的食堂都出现就餐高峰时结算餐费缓慢和人工结算失误等问题,因而设计出一套快速且准确的餐费自动结算系统是极为重要的。文章基于RFID无线射频识别技术设计了一套智能的餐盘自动结算系统,采用了ARM-Stm32作为系统主控板、RFID作为识别技术、TFT-LCD作为显示模块等,选用二进制树算法作为RFID无线射频技术防碰撞的主要算法,最终系统通过射频识别餐盘的数量与类型计算出就餐的费用,从而实现餐费的无人自动结算等功能。用户可在开发板上查看就餐餐费、一卡通个人信息及余额情况,最后用户只需刷一卡通完成支付。

Nowadays, the canteens of major enterprises and colleges and universities across the country have some problems, such as slow settlement of meal expenses and manual settlement errors, so it is very important to design a set of fast and accurate automatic meal settlement system. In this paper, a set of intelligent dinner plate automatic settlement system is designed based on RFID radio frequency identification technology. ARM-Stm32 is used as the main control board, RFID as the identification technology, TFT-LCD as the display module and so on. Binary tree algorithm is selected as the main anti-collision algorithm of RFID wireless radio frequency technology. Finally, the system calculates the cost of dining through the number and type of radio frequency identification plates, so as to realize the unmanned automatic settlement of meals. Users can view the dining expenses, one-card personal information and balance on the development board, and finally the user only needs to swipe one card to complete the payment.
