基于实时流量自动监测的引排水量测次优化探析

Analysis on optimization of diversion and drainage measurement based on real-time flow automatic monitoring

基于实时流量自动监测数据进行引排水量流量测验测次优化研究,以九曲河闸水文站为研究对象,在一定的工况条件下,以最少测次或一个测次达到以5分钟的实时流量自动监测数据进行水量计算的同等效果,即等效时刻流量的测验规律分析研究。将引水期间闸门调度变动情况进行分类,根据不同类型的工况分别进行引水总量的统计,并与5分钟的流量自动监测数据进行对比分析,结果表明:在闸门正常开关或者在高潮后开闸闸门变动有规律的的情况下可以确定等效流量的时刻,该时刻一般在高潮位后25分钟左右。研究可为其他实时流量自动监测测站和不同设备类型进行流量测次优化的分析提供新思路。

This paper mainly introduces the research on the optimization of diversion and drainage flow test based on real-time flow automatic monitoring data.Taking the hydrologic station of Jiuqu River Sluice as the research object,under certain working conditions,the same effect of water quantity calculation with 5-minute real-time flow automatic monitoring data can be achieved by using at least one test or one test,that is,the analysis and research on the test law of equivalent time flow.The changes of gate dispatching during the diversion period are classified,and the total amount of water diversion is counted according to different types of working conditions,and compared with the 5-minute flow automatic monitoring data.The results show that the moment of equivalent flow can be determined when the gate is switched normally or when the gate changes regularly after the most exciting part,which is generally about 25 minutes after the high tide level.This study can provide an idea for the analysis of flow measurement times optimization of other real-time flow automatic monitoring stations and different equipment types.
