无人船系统在淮安四线船闸工程流量测验中的应用

Application of unmanned vessel in flow test of Huai′an Fourth Line Ship Lock Project

无人船凭借其灵敏性强、运行速度快、方便便捷等优势,目前已广泛应用于水质监测及水下地形测量领域,但在水文流量测验领域应用较少。主要介绍了无人船系统的组成、测流原理以及技术优势,并结合淮安四线船闸工程水文流量测验,详细介绍无人船系统测流的方法并分析影响测验精度的因素。结果表明:基于北斗高精度全球定位系统与无人船自动控制技术的无人船系统,不仅提高了测流效率,降低了人员涉水风险,且在复杂水域条件下,精度可靠。

With the advantages of high sensitivity,fast operation and convenience,the unmanned vessel has been widely used in water quality monitoring and underwater topographic survey,but less in hydrological flow measurement.This paper mainly introduced the composition,current measurement principle and technical advantages of unmanned ship system.Combined with the hydrologic flow measurement of the Huai′an Fourth Line Ship Lock Project,it introduced the method of flow measurement of the unmanned ship system in detail,and analyzed factors that affected accuracy of the flow test.The results showed that the unmanned ship system based on Beidou high-precision global positioning system and unmanned ship automatic control technology can improve the flow measurement efficiency,reduce the risk of personnel wading,and make the accuracy more reliable under complex flow conditions.
