高可信度H-ADCP流量自动监测系统关键技术研究与应用

Study and Application of a High Credibility H-ADCP Flow Automatic Monitoring System

当前H-ADCP在我国得到广泛应用,特别是长江中下游平原河网地区,已成为水文流量测验的重要组成部分。但普遍缺乏对测流原始数据的分析检验,导致测流精度及成果可信度不高,以及比测率定工作繁杂等问题,影响HADCP的进一步推广应用。针对上述问题,根据H-ADCP测流原理,结合平原河网地区及感潮河段水文特性,提出了一种基于国产测控平台的高可信度H-ADCP流量自动监测和分析处理系统设计方案,具有测流原始数据分析处理、测流支架自动升降、比测率定分析等功能。经实践应用,可有效识别和剔除异常测流数据,提高流量监测成果精度,值得推广应用。同时,展望了旋转扫描和多高层联合扫描两种新技术路线。

H-ADCP is widely used in China.Especially in the middle and lower reaches of the Yangtze River,it has become an important part of hydrological flow measurement.However,there is a general lack of analysis and verification of the original data of flow measurement.That leads to low accuracy and reliability.And it also makes comparison test and calibration more complicated.In view of the above problems,and according to the principle of H-ADCP,combined with the hydrological characteristics of plain river network area and tidal reach,this paper designs a high credibility H-ADCP flow automatic monitoring and analysis processing system based on domestic measurement and control platform.This system can analyze and verify the original data of the flow measurement,automatic lifting of flow measurement bracket,comparison test and calibration.By application,this system can effectively identify and eliminate anomalous flow measurement data,improving the accuracy of flow monitoring results.It’s worth popularizing and applying.At last,this paper prospects two types of new technology:rotary scanning and multi-level joint scanning.
