全自动电波流速仪缆道在流速修正技术中的应用

The application of flow rate correction technology by fully automatic radio wave current meter cableway

电波流速仪作为一种常用的水文监测设备,在实际应用中常会出现个别测点数值超出合理范围的情况。为减少流量测验中垂线流速人为修正的随意性,依据历年实测测速垂线形成的数据,动态拟合基于特定垂线的水位流速关系曲线,对于偏离关系曲线较远的实测流,系统软件予以动态纠正。通过垂线流速异常值智能识别和修正系统软件的开发和应用,实现了垂线流速异常值的批量识别和修正,有效保障了复杂测流环境下雷达波测流成果的精准度和可靠性。

After years of improvement and development,radio wave current meter has gradually become a commonly used hydrological monitoring equipment.However,in practical applications,there are often cases where individual measurement point values exceed a reasonable range.To reduce the arbitrariness of manual correction of vertical flow velocity in flow testing,large data formed on the vertical lines of measured velocity over the years are used to dynamically fit the water level and velocity relationship curve based on a specific vertical line.For measured flows that deviate significantly from this relationship line,the system software dynamically corrects them.Through the development and application of intelligent recognition and correction system software for abnormal values of vertical flow velocity,batch recognition and correction of abnormal values of vertical flow velocity have been achieved,effectively ensuring the accuracy and reliability of radar wave flow measurement results in complex flow measurement environments.
