四女寺闸水文站影像法流量测验系统率定分析

Analysis of The Rate Determination of The Image Method Flow Test System at The Sinusi Gate Hydrological Station

为解决传统流量测验工作强度大、效率低、危险性高、自动化功能不足等问题,德州水文中心于2021年先后在四女寺闸南运河、减河和漳卫新河三处闸下断面安装影像法流量测验系统,同时与ADCP开展比测率定工作。影像法流量测验系统主机型号为TC-H546G,配置44X/IWS/H,测速范围0.2 m/s~15 m/s,测量精度±8%,最大测程100 m。实践表明,该系统具有多种功能,可满足高水平水文监测需求,对于提升水文监测水平具有重要的意义。

In order to solve the traditional flow test work intensity,low efficiency,high risk,lack of automation features and other problems,Texas Hydrological Center in 2021 has been in the four women's Temple lock South Canal,the River and Zhangwei New River under the three lock cross-sections to install the image method flow test system,and at the same time with ADCP to carry out the ratio measurement rate determination work.The image method flow test system host model TCH546G,configuration 44 X/IWS/H,measurement speed range 0.2 m/s~15 m/s,measurement accuracy±8%,the maximum measurement range of 100 m.practice shows that the system has a variety of functions,can meet the needs of high-level hydrological monitoring,for improving the level of hydrological monitoring is of great significance.
