徑流泥沙自動監(jiān)測儀器全天候無人值守能夠自動完成水樣采集、測量、數(shù)據(jù)處理及傳輸?shù)纫幌盗胁僮鳎瑴p少人工干預,提高監(jiān)測效率。實現(xiàn)24小時不間斷監(jiān)測,及時捕捉水體中泥沙含量的變化,為決策提供實時數(shù)據(jù)支持。采用先進的傳感器和算法,確保測量結(jié)果的準確性和可靠性。例如,泥沙含量測量精度可小于3%,徑流流量誤差小于3毫升/秒。儀器內(nèi)置大容量存儲器,可存儲大量歷史數(shù)據(jù)。同時,支持多種通信方式(如RS485、GPRS等),將數(shù)據(jù)實時上傳至云平臺或監(jiān)控中心,便于用戶隨時隨地調(diào)取、分析與管理數(shù)據(jù)。低維護成本儀器設計簡潔,結(jié)構(gòu)合理,易于維護和保養(yǎng),降低長期運行成本。部分儀器還具備自動清洗和校準功能,進一步減少了人工維護的頻率。

徑流泥沙自動監(jiān)測儀器

一、產(chǎn)品介紹
徑流泥沙自動監(jiān)測儀器在徑流場與小流域的水土流失監(jiān)測工作中,傳統(tǒng)人工測量流量和泥沙等數(shù)據(jù)存在工作量龐大、效率低下的問題,同時人力成本高數(shù)據(jù)誤差大。水土流失自動監(jiān)測系統(tǒng)歷經(jīng)多年技術(shù)攻關(guān)與大量實地試驗驗證,成功實現(xiàn)對傳統(tǒng)人工監(jiān)測模式的革新。
本系統(tǒng)由數(shù)據(jù)采集主控機、含沙量測量傳感器、明渠流量傳感器和降雨量傳感器構(gòu)成。其中,明渠流量傳感器組件可自動測量徑流流量,并通過控制器精準計算不同時間段的徑流總量與瞬時徑流數(shù)據(jù);含沙量測量傳感器依據(jù)徑流變化特征,于徑流垂直分布的泥沙測量口,實時采集徑流含沙量數(shù)據(jù);降雨量傳感器則負責精準獲取累計雨量數(shù)據(jù)。各傳感器協(xié)同作業(yè),所采集數(shù)據(jù)對水土流失分析具有關(guān)鍵價值。
系統(tǒng)將各傳感器采集的泥沙含量、徑流量和累計雨量數(shù)據(jù)實時上傳至云平臺,便于用戶隨時隨地調(diào)取、分析與管理數(shù)據(jù),為水土保持決策提供科學、精準的數(shù)據(jù)支撐。
泥沙含量傳感器工作流程:地表水體由引水槽進入明渠或巴歇爾槽并經(jīng)過明渠流量計獲得瞬時徑流量數(shù)據(jù),并計算出單位時間內(nèi)的徑流總量,分水管采集到地表水體送入主水箱,當主水箱待測地表水容量足夠進行檢測時,系統(tǒng)啟動并將待測地表水送入樣品倉進行檢測,傳感器把收集到的數(shù)據(jù)送給處理器經(jīng)處理后得到泥沙含量,得到數(shù)據(jù)后傳感器把內(nèi)部樣品由排水管排出為下次采樣做好準備。處理器通過485輸出至外部設備。

五、維護和保養(yǎng)
初次使用前請先擰松運輸固定桿,否則設備將無法正常工作。
初次使用或久置不用重新使用時,請重新進行清水校準和零點校準。
定期檢查儲水箱,如有污泥大量沉積或有雜物,請進行清除,可拆下排水閥并沖洗干凈。
定期檢查排水閥,樣品桶進水閥,樣品桶排水閥,水流流通是否通暢,如水流弱小或不通水,可取消排水閥上的控制線并拆卸下排水閥進行清洗,然后重新安裝回去。
保持設備內(nèi)部整潔,稱重部分禁止物品堆積,樣品桶下禁止放置物品。
設備所在區(qū)域溫度低至零下時,請排空設備內(nèi)部水分,放置結(jié)冰損壞設備。
傳感器使用時間較長出現(xiàn)測量誤差時,可通過配合儀器進行標定校正,當以上方式對傳感器進行維護和保養(yǎng)仍不能進行標定和測量時,說明傳感器已經(jīng)損壞。
