武大AiFlow视觉测流产品在黄河流域的应用研究

Application Research of Wuhan University AiFlow Visual Flowmeter Product within the Yellow River Basin

摘要: 本文以黄河流域为例，通过使用武大AiFlow视觉测流产品开展了数据采集、处理、率定以及与转子流速仪、声学多普勒流速剖面仪(Acoustic Doppler Current Profilers, ADCP)等常规设备的测流结果进行误差分析工作，以此来检验武大AiFlow视觉测流产品在大江大河的适用性与可靠性。研究结果表明，武大AiFlow视觉测流产品精度满足规范要求，能够在较短时间内获取高精度的流量数据，从而实现对大型河流水文站的流量实时在线监测。

Abstract: This paper takes the Yellow River Basin as an example, utilizing the Wuhan University AiFlow Visual Flowmeter Product to conduct data collection, processing, calibration, and error analysis by comparing with those obtained from traditional equipments such as rotating-element current-meters and Acoustic Doppler Current Profilers (ADCP) to validate its applicability and reliability in large rivers. The results indicate that the accuracy of this product meets the regulatory requirement and it is capable of obtaining high-precision flow data in a short time. Thus it can be used to realize the real-time online monitoring of hydrological stations in large rivers.
