應用無線感測網（WSN）提升乳牛場經營管理之研究

本研究之目的為建立一套無線感測網系統以提升臺灣乳牛場之經營效率，本系統包括：I.牛舍環境感測器：即時監測溫度與相對溼度，當溫度超過預設定臨界值時，便自動啟動牛舍降溫設施如風扇、噴水、噴霧等，除可精準環控外並達省水省電之效果。II.牛隻無線型發情偵測器系統：內建震動感測器封裝成脚環形式，固定於空胎牛隻前脚，24小時自動紀錄牛隻步伐震動數與體位之變化，並精準找出牛隻發情的時間點，再經由電腦即時發送簡訊或傳真及發送電子郵件給牛群管理者。結果顯示，應用牛舍環境感測器後，牛舍夏季用電量相較於往年約可節省25%。牛隻無線型發情偵測器系統應用於3家乳牛場進行田間測試，結果指出牛隻（n=70）發情偵測器之準確度平均介於87.5－95%，此結果深受測試季節之影響。本研究結論認為，應用無線感測網於乳牛場，除可精準環控外並可達省水省電之效果，又可減少人力去觀察牛隻發情及提高發情判斷之準確度，進而提升乳牛場整體之經營效率。

The purpose of this study was to establish a wireless sensor network system of dairy farm in Taiwan. Those systems were composed of barn environment sensors and wireless cattle heat detector system. The environment sensor system can be used for detecting ambient temperature and relative humidity. The system starts the barn cooling facilities such as fans and water spray when the ambient temperature exceeds the maximum setting. According to the power consumption data in summer 2011, the environment sensor system reduced about 25% of electricity costs. The cattle estrus detection system of wireless sensor network was applied on two dairy farms in Taoyuan and Natou country to do field tests. The results showed that accuracy of cattle estrus detection sensors were between 87.5-95%. It seemed that accuracy of cattle estrus detection sensors was mainly effected by temperature in different season. Results proved that wireless sensor network can applied to dairy farms, not only can save costs but also reduce visual observation time and can improve the accuracy of estrus judgment. This wireless sensor network system had superior benefits on saving barn power and keeping cattle estrus detection accuracy, and further to improve farm management efficiency.
