水文信息勘測
行業(yè)背景

聲學(xué)多普勒流速剖面儀 (ADCP) 是水體流場測驗(yàn)中非常重要的高科技儀器，在水文行業(yè)流量測驗(yàn)領(lǐng)域得到了廣泛應(yīng)用，并逐步取代其它種類的流量測量儀器。目前國內(nèi)使用的河流型 ADCP 基本依賴進(jìn)口，核心技術(shù)長期由國外壟斷。由于水文行業(yè)具有極強(qiáng)的公益性、基礎(chǔ)性、戰(zhàn)略性，關(guān)系到經(jīng)濟(jì)安全、生態(tài)安全和國家安全，急需河道流量測驗(yàn) ADCP 商業(yè)化產(chǎn)品國產(chǎn)化。

解決方案

中海達(dá)iFlow系列聲學(xué)多普勒流速剖面儀，配備自主研發(fā)的iFlow測流軟件。可測量流速流量，斷面等數(shù)據(jù)。 作業(yè)過程：
1. 搭載平臺：可搭載于中海達(dá)iBoat無人船、三體船、側(cè)舷、在線監(jiān)測平臺等；
2. 軟件：支持外接測深儀數(shù)據(jù)和GNSS數(shù)據(jù)有效解決動底和高沙等復(fù)雜環(huán)境。設(shè)置簡單，符合國人操作習(xí)慣；
3. 成果：支持水深、坐標(biāo)、流速、流量等多種數(shù)據(jù)成果導(dǎo)出。

方案優(yōu)勢

1.iFlow系列走航式聲學(xué)多普勒流速剖面儀，是中海達(dá)自主設(shè)計(jì)、研發(fā)和生產(chǎn)的活塞式ADCP產(chǎn)品，產(chǎn)品綜合性能達(dá)到國際先進(jìn)水平，產(chǎn)品通過了水利部新產(chǎn)品鑒定，入選了水利部《水文測報(bào)新技術(shù)裝備推廣目錄》；

2. 流速剖面量程 80 米，測流精度高達(dá) 0.25%±0.2cm/s ，產(chǎn)品綜合性能達(dá)到國際先進(jìn)水平；

3. 支持 RS232、RS422 以及 WIFI 數(shù)據(jù)傳輸方式，支持走航測量模式、定點(diǎn)測流模式以及自容測量等模式；

4. 完全自主研發(fā)測流軟件，可根據(jù)用戶需求進(jìn)行定制開發(fā)。

應(yīng)用案例
三峽庫區(qū)某段航道水下地形項(xiàng)目
中海達(dá)多波束測深儀本次測區(qū)為三峽庫區(qū)某段航道，水深在50-180米不等，水下地形變化較大，多陡峭地形。為準(zhǔn)確掌握該段航道的水下地形情況，現(xiàn)場技術(shù)人員使用iBeam 8140P多波束測深系統(tǒng)開展水下地形測繪工作。
