Comparison and Analysis of On-Line Acoustic Doppler Current Profiler

在线式声学多普勒流速剖面仪(On-line Acoustic Doppler Current Profiler)可自记测验点的水位、指标流速、水温等特征值,数据的采集、处理均可在现场完成,自动化程度高,且操作简单,能够快速、实时、连续测量,要实现在线ADCP在不同断面的应用,必须分析指标流速与断面平均流速之间的关系。本文以虎山站为例,简述在线式声学多普勒流速仪的比测分析,为河道站在线ADCP流量测验问题提供可行解决方案以及应用案例。

On-line Acoustic Doppler Current Profiler (ADCP) can record the characteristic values of water level, index velocity and water temperature of test points by itself. Data acquisition and processing can be accomplished on site with high automation, simple operation, fast, real-time and continuous measurement. In order to realize the application of on-line ADCP in different sections, it is necessary to analyze the relationship between index velocity and average cross-section velocity. Taking Hushan hydrologic station as an example, this paper briefly describes the comparison and analysis of online acoustic Doppler velocimeter, and provides feasible solutions and application cases for on-line ADCP stream flow measurement.
