[0020] Reference Figure 1 The utility model provides a hydrological flow measurement device combining thunder and vision, including a thunder and vision fusion flow meter 1.

[0021] Specifically, the radar-visual fusion flowmeter 1 includes a fuselage 11, and the fuselage 1 is equipped with a radar monitoring module and a visual monitoring module. The radar monitoring module is used to collect basic water flow data through a radar sensor, and the visual monitoring module is used to collect visual water flow data; the fuselage also includes a fusion module, and the fusion module is used to fuse the basic water flow data and the visual water flow data; the fusion module is electrically connected to the radar monitoring module and the visual monitoring module.

[0022] The basic water flow data include water level data and flow rate data; and the water flow visual data include water body surface image data.

[0023] Specifically, the radar monitoring module includes a radar water level sensor 12 for monitoring the water level and a radar flow measurement sensor 14 for monitoring the flow velocity of the water body.

[0024] The radar water level sensor 12 and the radar flow measurement sensor 14 are both radar sensors, which can monitor the height of the water body or the flow rate of the water body by sending radar waves and obtaining echoes and performing calculations through the Doppler effect.

[0025] In order to achieve a good water level monitoring effect, the radar wave emission direction of the radar water level sensor 12 is set vertically downward.

[0026] In order to achieve accurate monitoring of water flow rate and avoid the monitored target flow out of the measurement range, the radar wave emission direction of the radar flow measurement sensor 14 is set to be tilted downward to expand the monitoring sampling area.

[0027] In the present invention, the visual flow measurement sensor 13 adopts a high-precision camera or a high-precision camera. In order to adapt to different lighting environments such as day and night or cloudy and sunny, the visual flow measurement sensor 13 can adopt an all-day visual sensor.

[0029] The fusion module is used to collect and process the data from the radar monitoring module and the visual monitoring module. Specifically, a conventional publicly available edge fusion algorithm can be used for data fusion.

[0030] In one embodiment, the hydrological flow measurement device with thunder and vision fusion may include a plurality of thunder and vision fusion flow meters 1, and the thunder and vision fusion flow meters 1 are installed at equal intervals on the upper facilities of the external water body.

[0031] Exemplary, reference Figure 2 As shown, when the width of the water body to be monitored is large, such as a river water body with a width of more than 100 meters, multiple radar-vision fusion flow meters 1 can be installed at equal intervals on upper facilities of the water body such as bridges, such as setting a radar-vision fusion flow meter 1 at intervals of 30 to 50 meters, to achieve hydrological monitoring of wide water areas.

[0032] The radar-vision fusion current measuring instruments 1 are installed at equal intervals below the bridge 7 and above the water area.

[0033] In another embodiment, the hydrological flow measurement device with thunder and vision fusion includes a bracket 10, and the thunder and vision fusion flow meter 1 is installed on the upper end of the bracket 10. The bracket 10 can be set on the shore of the water body to achieve hydrological monitoring.

In specific use, the radar fusion current meter 1 monitors the water level data and flow rate data of the current water area through the radar water level sensor 12 and the radar flow sensor 14, and fuses the data through the fusion module in the controller 2. After fusion, the surface flow rate and flow of the water area are calculated. It is wirelessly transmitted to the base station through the transmission module 5, and can be viewed through the cloud and APP.
