浮标式流量在线监测系统在潮汐河道应用经验

Application Experience of Buoy Online Flow Monitoring System in Tidal Channel

河流流量监测是水文测验任务的重要内容,然而之江站由于往返的潮流、较宽的河流断面,常用的固定ADCP、雷达等自动测流系统难以取得好的测验效果。近年随着各种流量在线监测技术逐步成熟,为了实现之江水文站的流量测验的自动化及智能化,站点在2019年引入一套先进的浮标式流量在线监测系统,获取较好的投放及应用成果,并进一步总结探讨此类断面的流量自动测验推广应用经验。

River flow monitoring is an important part of the hydrological testing task.However,due to the round flow and wide river cross section,Zhijiang Station has difficulties in getting good results with the automatic current measurement system such as fixed ADCP or radar system.With new development of online monitoring technology in recent years,in order to realize automatically and intelligently flow measurement,Zhijiang station introduced an advanced float type flow online monitoring system in 2019.Based on the current results,the system has gained promising results and can introduce and apply to other stations with similar environmental conditions.
