The non-contact type radar wave velocity instrument is used as water velocity measurement sensor to realize the automatic flow test of hydrological station,.which can solve the problem of automatic flow test of small and medium-sized rivers and mountainous rivers with rapid Water rise and fall under the condition of unattended operation.Based on the research of centralized flow monitoring and management platform,a centralized control center can control several remote hydrological stations to measure flow.After setting parameters of flow measurement interval,representing vertical and others in system software,the system will automatically measure flow and intelligently control whole flow measurement process without artificial intervention.At the same time,the centralized control center can monitor and remote control the flow measurement of each station at any time.%以非接触式雷达波流速仪作为水面流速测验传感器,实现了水文站流量测验的自动化,很好地解决了无人值守条件下中小河流、山区性暴涨暴落河流流量自动测验难题.通过流量在线监测集控管理平台的研究,实现了一个控制中心集中控制多个远端水文站测流.在系统软件中设置好测流时间间隔、代表垂线等参数,系统将根据设定的参数进行自动测流,并在无人状态下自动对测流全过程实行智能控制;同时,集控中心可随时监视、远程控制各测流站工作.
