摘　　要：该文介绍了武大AiFlow视频测流技术在汤溪水文站的应用结果,以汤溪水文站2023年10月—2024年1月走航式ADCP实测结果与武大AiFlow视频测流数据进行率定分析,结果表明:断面流量系统误差为0.08%,随机不确定度为13.50%,关系曲线检验中的符号检验、适线检验、偏离数值检验均合格,符合《水文资料整编规范》(SL/T 247—2020)的规定要求,实现了水库出库流量的自动化监测需求,为现代化水文站建设及智慧水利数字孪生系统发展提供了有力支持。This paper introduces the application results of Wuhan Universitys AiFlow video flow measurement technology at Tangxi Hydrological Station.Based on the calibration analysis of the ADCP measurement results and the AiFlow video flow data from October 2023 to January 2024 at Tangxi Hydrological Station,the analysis results show that:the systematic error of the cross-section flow is 0.08%,the random uncertainty is 13.50%,and the sign test,linearity test,and deviation value test of the relationship curve are all qualified,meeting the requirements of the“Hydrological Data Compilation Specification”(SL/T 247-2020),realizing the automatic monitoring of the reservoir outflow,and providing strong support for the construction of modern hydrological stations and the development of smart water digital twin systems.
