Problems solved by technology

However, domestic research on non-contact radar flow measurement equipment is less, and mature products have not yet been formed.
[0004] On the one hand, the radar current velocity measurement equipment measures the surface velocity of the water body, and the wind speed may affect the surface velocity, especially near coastal rivers such as estuaries, thereby affecting the radar velocity measurement results, so it is necessary to correct the velocity measurement results

Description

technical field [0001] The invention relates to a monitoring integrated device, a monitoring system and a monitoring method, in particular to a water level, velocity and flow monitoring integrated device, a monitoring system and a monitoring method, belonging to the technical field of hydrological monitoring. Background technique [0002] In hydrological monitoring, flow monitoring is the core content, and it is also the most difficult item in monitoring. Traditional monitoring methods generally need to rely on surveyors to launch into the water. Flow measurement is heavy, time-consuming, and low in efficiency. It has a lot to do with the experience and technology of personnel, and it is even more difficult to realize the flow measurement in flood period. [0003] With the advancement of water conservancy information technology, non-contact measurement technology has made great progress with the advantages of safe and efficient measurement methods and accurate measurement re...
