水塘的無人船系統 水塘的原水是香港的主要食水來源之一。水務署定期監測水塘 的水質和抽取樣本，以便下游濾水廠更有效控制食水處理過 程，確保食水安全。 為提升水塘水質監測，我們引入了嶄新的無人船系統，在船灣 淡水湖進行自動監測水質和取樣，透過採用創新科技，提升緊 急狀況應變能力和運作效率。採用多艘無人船進行水質監測， 既可以增加監測的覆蓋範圍，亦可增加監測點數量。從而提升 整個水塘表面水質的監測效率。 二零二一年八月，無人船系統的應用已擴展至萬宜水庫，進 行自動水質監測。隨著實踐取得成功，無人船系統應用已於 二零二二年九月進一步擴展至大欖涌水塘。我們計劃提升系統 的智能，讓無人船系統能夠自動規劃航線和作出應變。透過 提升系統的智能，當無人船系統上的實時感應器錄得異常讀數 時，無人船系統能夠自動增加監測點以收集更多數據及進行額 外取樣。 Unmanned Surface Vessels System at Impounding Reservoirs Raw water in impounding reservoirs is one of the major drinking water sources in Hong Kong. We monitor water quality and collect water samples in impounding reservoirs on a regular basis which facilitate the effective control of water treatment process at downstream water treatment works to ensure the safety of drinking water supply. To advance water quality monitoring, we have introduced a new unmanned surface vessel (USV) system to perform automatic water quality monitoring and sampling in the Plover Cove Reservoir, boosting emergency responsiveness and operational efficiency through the adoption of innovation and technology. The use of multiple USVs for water quality monitoring allows parallel operation to increase coverage and the number of monitoring points which enable the effective capture of the water quality of the whole reservoir surface. In August 2021, the USV system was also deployed in the High Island Reservoir for automatic water quality monitoring. Following these successful trials, the application of the USV system was extended to the Tai Lam Chung Reservoir in September 2022. We plan to enhance the intelligence of the system with the introduction of automatic route planning and response. The enhanced system can automatically increase the number of monitoring points to collect more data; as well as additional water samples from the reservoir when abnormal water quality is detected by the real-time sensors of the USV. 利用無人船在船灣淡水湖進行水質監測 USV conducts water quality monitoring in the Plover Cove Reservoir 安裝在無人船底部的水質監測儀可以實時監測水質 Water quality monitoring unit is installed under the bottom of the USV for real-time monitoring of water quality 現新 Innovate 水務署 二零二一至二二年年報 WSD Annual Report 2021/22 44
