在长江上游水库调度的影响下,下游水文站流量变化频繁,采用常规方法难以准确测量到流量变化过程。为此,长江干流黄陵庙水文站利用水平式声学多普勒流速剖面仪( H-ADCP)进行了流量在线监测。介绍了在线监测系统的流量推算原理、信息采集系统结构以及实时信息处理过程。将H-ADCP实时监测结果与传统方法所测流量进行了对比分析,结果表明,其测量误差和随机不确定度均较小。
在長江上遊水庫調度的影響下,下遊水文站流量變化頻繁,採用常規方法難以準確測量到流量變化過程。為此,長江榦流黃陵廟水文站利用水平式聲學多普勒流速剖麵儀( H-ADCP)進行瞭流量在線鑑測。介紹瞭在線鑑測繫統的流量推算原理、信息採集繫統結構以及實時信息處理過程。將H-ADCP實時鑑測結果與傳統方法所測流量進行瞭對比分析,結果錶明,其測量誤差和隨機不確定度均較小。

Under the influence of reservoirs regulation at upper Yangtze River, the discharge of hydrological stations at down-stream changes frequently, so it is difficult to correctly monitor the changes of discharge using conventional method. Therefore, for downstream Huanglingmiao Hydrological Station of Three Gorges Project, H-ADCP ( Acousitc Doppler Current Profiler) was adopted for online discharge monitoring. The discharge estimation principle, structure of information collection system and online information processing are introduced. The monitoring results of H-ADCP are compared with those of conventional methods and the results show that the error and random uncertainty are smaller.
