Description

technical field [0001] The invention relates to the technical field of flow measurement, in particular to a radar for precise measurement of river surface flow field based on computing intelligence. Background technique [0002] The real-time flow of rivers is the most important data in hydrology, water resources management and water conservancy engineering, and is an important content in the construction of smart hydrology. Traditional hydrology is limited by climate, measurement methods, safety, and response time. Flow measurement has always been a difficult point in today's hydrological measurement. Traditional contact flow measurement schemes often have the following disadvantages and cannot be arranged or measured normally: during high flood periods, the river flow velocity is fast, the sediment content is high, and there are many floating debris, which is easy to cause damage to the instrument and threaten personal safety; the water flow in the dry season is small , t...

Problems solved by technology

The radio wave current meter using the point flow velocity measurement method has high requirements for the installation location. It needs to be installed above the water surface with the help of bridges or cantilever brackets. Since the radio wave current velocity instrument can only obtain single-point flow velocity data, if the river surface is wide, multiple radio waves. Velocity Simultaneous work of instruments is expensive
