重量的量測是動物飼育過程中一項重要的項目，若需同時管理大量的動物，則可配合RFID動物標籤來執行。然而，RFID動物標籤難以由人眼直接判讀，且整合RFID標籤資料與重量、時間等資料的過程繁雜。因此建構一套快速、簡單的RFID動物重量管理系統是必須的。本系統以單晶片微電腦Arduino為核心，使用通用串列匯流排USB供電，透過荷重元Load Cell獲得重量，由RTC取得時間，並利用藍芽模組與RFID Reader連線。Arduino 先將Reader傳來的資料解碼，再將RFID Tag、重量、日期與時間等資料整合，最後顯示於液晶顯示器上並儲存於SD卡中。使用者取得SD卡資料後，可透過電腦端動物重量管理系統，儲存至料庫，或上傳至雲端。透過本系統，現場量測與紀錄動物重量時，不需攜帶電腦與紙筆，也不用尋找插座，輕巧方便。手持機與磅秤透過藍芽連線，沒有傳輸線的阻礙，可隨意移動，找尋Reader最佳的讀取位置。本系統徹底改善了傳統人工紀錄的缺點，有效提升動物管理者的工作效率。
關鍵語：無線射頻辨識、單晶片、藍芽

Weight measurement is an important process in animal breeding. Radio Frequency Identification, RFID, tags can reduce the mistakes in identifying animals. However, RFID animal tags is not easy interpreted directly by the human eyes, and the integration of tag information with time and weight data need further computing process. Therefore, to construct a fast and simple RFID animal weight management system is important. The system is a single-chip microcomputer, Arduino, powered by Serial Bus (USB). Weight data is calculated from Load Cell, time is catch by Real-time clock, RTC and bluetooth modules supporting RFID Reader connection. Arduino first decode the data coming from the Reader and integration with weight, date and time data, and finally displayed on the LCD monitor and stored in the SD card. Users can use the SD card directly via computer, or save it into remote cloud database. Through this system, researchers can carry out field animal weight measurements without desktop or notebook computer. USB Arduino integrates RFID handset with wireless Bluetooth scale. There is no obstacle transmission line, free to move, and easy to find the best position for reading tags. The system can provide a better alternative to hand weight recording and increase the efficiency of animal management.
Key words: Radio frequency identification, Arduino, Bluetooth
