QT基於RFID管理系統（可應用於大多數RFID管理系統）

本系統由QT編譯，可應用於大多數基於RFID的管理系統，可進行端口設置，進出系統物品查詢等基本功能！

此課題全部說明書以及程序包已打包！需要的私信取！

系統實現:

將RFID技術引入櫃臺貴重物品管理系統，為貴重的櫃臺商品綁定RFID標簽，結合安裝在櫃臺上的RFID識別設備用來監測、控制和跟踪貼標的貴重物品，實現快速盤點、實時跟踪及銷售的智能管理。從而對櫃臺貴重物品產品的進出和銷售過程進行全方比特的跟踪和記錄，用自動化和准確高效的新方法取代了繁瑣和低效的人工管理和條碼掃描模式。並能做到短距離離開櫃臺（3~5米）報警，未能取得授權情况下，破壞或解除RFID標簽與貴重物品的綁定報警。

1. 總體方案設計（論證）

2. RFID卡設計

(1) 射頻識別技術；(2) 電子標簽的選擇。

3. RFID讀寫器硬件設計

(1) MCU；(2) 射頻模塊；(3) 天線；(4) 通信接口；(5) 人機界面；(6) 電源電路。

4. RFID讀寫器軟件設計

(1) 系統初始化程序；(2) 對卡操作程序；(3) 液晶顯示程序。
