AI Technical Summary

Technical Problem

Existing ADCP cableway flow measurement technology has difficulty dynamically identifying the true flow layer boundary in sediment-laden water bodies, resulting in a mismatch between the vertical velocity layer and the actual sediment distribution. Furthermore, it cannot ensure the consistency of flow data from multiple measurement points, introducing noise and systematic errors.

Method used

By dividing the cableway into equal-thickness depth units, the relative sediment content index is obtained, the flow measurement zones are dynamically combined, and a three-point flow measurement zone overlap verification mechanism is introduced to ensure the accuracy of flow data.

Benefits of technology

It enables precise identification of the flow layer boundary in sediment-laden water bodies, reduces the impact of environmental interference, ensures the accuracy and consistency of flow data, and improves the accuracy of cross-sectional flow fusion.

Abstract

This invention discloses a cableway flow measurement data processing method, system, device, and medium based on ADCP, belonging to the field of data processing technology. The method includes: acquiring depth cells, acquiring equidistant measurement points, and collecting echo intensity data of the depth cells; acquiring the relative sediment concentration index of the depth cells; combining the depth cells into flow measurement zones of equidistant measurement points according to the relative sediment concentration index of the depth cells; if multiple flow measurement zones of three consecutively adjacent equidistant measurement points overlap, then these three equidistant measurement points are taken as target measurement points, and flow data of multiple flow measurement zones are collected at the three target measurement points using ADCP mounted on the cableway, and the flow measurement result is obtained based on the flow data of multiple flow measurement zones at the three target measurement points. This invention has the advantages of self-adaptation, strong anti-interference ability, and data collaborative verification.
