Description

technical field [0001] The invention relates to the technical field of flow measurement, in particular to a radar for accurate measurement of river surface flow field based on computational intelligence. Background technique [0002] The real-time flow of rivers is the most important data in hydrology, water resources management and water conservancy projects, and is an important content in the construction of smart hydrology. Traditional hydrology, limited by climate, measurement methods and safety, response time, etc., flow test has always been a difficult point in today's hydrology measurement. The traditional contact flow measurement scheme often has the following shortcomings and cannot be arranged or measured normally: the river flow in high flood season 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; low water flow in dry season , the water depth of some rivers is...

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
