QT基于RFID管理系统（可应用于大多数RFID管理系统）

本系统由QT编译，可应用于大多数基于RFID的管理系统，可进行端口设置，进出系统物品查询等基本功能！

此课题全部说明书以及程序包已打包！需要的私信取！

系统实现:

将RFID技术引入柜台贵重物品管理系统，为贵重的柜台商品绑定RFID标签，结合安装在柜台上的RFID识别设备用来监测、控制和跟踪贴标的贵重物品，实现快速盘点、实时跟踪及销售的智能管理。从而对柜台贵重物品产品的进出和销售过程进行全方位的跟踪和记录，用自动化和准确高效的新方法取代了繁琐和低效的人工管理和条码扫描模式。并能做到短距离离开柜台（3~5米）报警，未能取得授权情况下，破坏或解除RFID标签与贵重物品的绑定报警。

1. 总体方案设计（论证）

2. RFID卡设计

(1) 射频识别技术；(2) 电子标签的选择。

3. RFID读写器硬件设计

(1) MCU；(2) 射频模块；(3) 天线；(4) 通信接口；(5) 人机界面；(6) 电源电路。

4. RFID读写器软件设计

(1) 系统初始化程序；(2) 对卡操作程序；(3) 液晶显示程序。
