The invention discloses a
water level-flow speed-flow rate monitoring integrated device, a
water level-flow speed-flow rate
monitoring system and a
water level-flow speed-flow rate monitoring method. The device comprises a
radar water level measuring module, a
radar flow speed measuring module, a
wind speed measuring module and a flow rate calculating module, wherein the
radar water level measuring module, the radar flow speed measuring module and the
wind speed measuring module are connected with the flow rate calculating module respectively; the radar water level measuring module is used for measuring the real-time water
level data of a river course / channel in a non-contact form; the radar flow speed measuring module is used for measuring the real-time surface flow speed data of the river course / channel in the non-contact form; the
wind speed measuring module is used for measuring real-time wind speed data to correct a flow speed of a water surface; the flow rate calculating module is used for calculating to obtain the size of the flow rate of a controlled section of the river course / channel at a current moment by combining with an input relevant parameter of the controlled section of the river course / channel according to the water
level data, the flow speed data and the wind speed data. The device can be used for monitoring the water level and the flow speed of the river course / channel in real time, and moreover, can be used for realizing monitoring the flow rate in real time.
