MYUAV water flow velocity measurement system: remote real-time data monitoring of water environment

1. Application background of MYUAV water flow velocity meter

MYUAV water flow velocity measurement technology has been widely used in fields such as hydrology, oceanography, and environmental monitoring. It can be used not only to measure water velocity in rivers, lakes and oceans, but also to monitor glacier melt, flood warning and water quality monitoring.

MYUAVs can be equipped with current meters, water temperature meters and water quality monitoring equipment for monitoring and researching ocean currents, marine environments and ecosystems. The measurement of water flow speed and direction by drones can help scientific researchers better understand changes in the marine environment and the dynamics of ecosystems; in the construction and operation of water conservancy projects, drones can be used to monitor rivers, reservoirs and waterways. Water flow conditions, timely detection of water flow abnormalities and diseases, to ensure the safe and stable operation of water conservancy projects; MYUAVs can be equipped with water flow monitoring equipment for rapid response to water rescue missions, and monitor and evaluate water flow conditions during flood disasters, providing Provide data support for rescue and disaster prevention.

2. System composition

The MYUAV water flow velocity measurement system consists of two parts: the air terminal and the ground terminal: including the MYUAV flying platform, water flow velocity meter, ground station and web control terminal.

Monitoring principle of MYUAV water flow velocity meter

When there is relative motion between a wave source and an observer, a change occurs between the frequency of the wave received by the observer and the frequency of the wave emitted by the source. In the application of MYUAV water flow velocity measurement, Doppler radar equipment will be equipped. Doppler radar detects water velocity by emitting high-frequency electromagnetic waves (such as radio waves or microwaves) into the water flow and receiving the reflected waves back. Doppler radar calculates the speed of water flow by calculating the difference between the frequency of the reflected wave and the frequency of the emitted wave. When the MYUAV is close to the water flow, the frequency of the reflected wave will be higher than the frequency of the emitted wave; when the MYUAV is far away from the water flow, the frequency of the reflected wave will be lower than the frequency of the emitted wave. By measuring the frequency difference, the speed of the water flow is calculated.

3. MYUAV water flow velocity meter monitoring process

1. Mission planning and preparation: Determine the water area and target area that need to be measured, and understand the specific requirements and purposes of water flow velocity measurement. Prepare drone equipment, including drone platform, water flow velocity meter, ground terminal, etc.

2. Flight path planning: Plan the flight path of the drone based on the characteristics of the target area and water flow conditions. Ensure that the flight path covers the entire measurement area while avoiding obstacles and flight restricted areas.

3. MYUAV take-off: Start the MYUAV and conduct a pre-flight inspection to confirm that the MYUAV and water flow velocity meter equipment are in good condition.

4. Measurement data collection: As the drone flies along the planned flight path, the water flow velocimeter starts to work, sending high-frequency signals to the water body and receiving echoes to obtain data on the water flow velocity.

5. Data processing and real-time monitoring: The collected data is processed internally to calculate the water flow speed information. The data is transmitted to ground stations or monitoring centers to monitor changes in water flow velocity in real time.

6. Data analysis and result output: Analyze and organize the collected data to form a report or chart of water flow velocity, and output it as a visual result.

7. End of flight mission: After the drone inspection mission is completed, it will land according to the preset safety procedures and end the flight mission.

8. Data post-processing: Conduct subsequent in-depth analysis of the large amount of collected data, including correction and error correction, to ensure the accuracy of the measurement results.

4. Web page monitoring function

Connect the water flow velocity meter to the software, and the flight can be controlled through the software platform.

1. Supports arbitrary switching of 2D maps or video base maps, supports selecting points and drawing lines on the map to plan routes, and aircraft fixed points.

2. Implement customized flow measurement tasks. The flow control mode supports automatic and manual tasks.

3. Monitor water flow data in real time. During the flow measurement process, check whether the cross-section flow velocity distribution map is reasonable and the real-time flow measurement data of aerial measurement points.

4. View flow measurement data, cross-section diagrams, and cross-section flow velocity comparison diagrams to calculate flow in real time. By importing cross-section data and inputting coefficients, the flow calculation results table can be calculated and exported.

5. Supports data recording, historical data, video review, and export of hydrological flow reports.
