Natural disaster protection and early warning: MYUAV water flow velocity meter helps flood prevention and rescue operations
Application overview
The natural flood peak period and flood season are the periods when river water levels and flow rates change most dramatically, so monitoring water flow rates is of extremely important significance.
When a flood occurs, the rapid increase in water flow velocity is one of the important indicators for flood warning. Through real-time monitoring of water flow, flood warnings can be issued in a timely manner, providing residents and relevant departments in downstream areas with valuable time for evacuation and flood prevention and disaster reduction.
The monitoring of flow rate is also crucial for the management and scheduling of water conservancy projects. Monitoring data helps to accurately analyze the evolution of floods, predict the impact range and possible damage of floods, and thus more effectively guide the deployment of flood control work; during the flood season, hydrological stations will decide whether to open based on data such as water flow speed and rainfall. Reservoir gates release floods to ensure the safety of the reservoir and the safety of downstream areas.
MYUAV YF-CL30 water flow velocity meter
The MYUAV YF-CL30 series UAV hydrological detector has the characteristics of high sensitivity, high measurement accuracy, fast response speed, and does not require maintenance and calibration of on-site measurements.
Compared with traditional detection methods, it can achieve non-contact measurement and is not affected by environmental factors such as temperature, humidity, and pressure. It has very high stability and can conduct accurate and real-time hydrographic and video monitoring of the area to be measured in the air, thus safely and accurately Reflecting water body conditions and providing water flow information improves the efficiency of handling emergency warnings, emergencies and disasters, and solves the shortcomings of slow manual operations and high risk factors.
The YF-CL30 UAV hydrological detector can currently be mounted on DJI M300 and M350 UAVs. The methane concentration data collected by the sensor can be transmitted to the remote control APP through various transmission methods such as 4G module and DJI SDK. Or web page display.
Application scenarios
MYUAV UAV hydrological monitor can be widely used in rivers and lakes, water resources monitoring, flood control command, mountainous rainstorm flood monitoring, geological disaster early warning monitoring and other fields. It is not affected by temperature, pressure, air density, wind or other meteorological environmental conditions. , can work stably around the clock and around the clock. Cooperate with web-based data software monitoring to monitor water speed changes in real time.
Web functionality
Automatically record and generate a flow statistics table for each measurement task, including key information such as time, location, starting point distance, water level, flow velocity, cross-sectional area, and flow rate.
1. Create cross-section data: basic cross-section information, route generation information, cross-section measurement point information, and cross-section export.
2. Section view: You can view the status information of the drone during flight and the raw data information measured by the sensor. After clicking it, you can drag the bottom progress bar to view the data at different times.
3. Real-time data: When the drone test data is not received, the vertical line measurement point is yellow. After the drone data is received and successfully compared with the current measurement point, the vertical line measurement point will turn green, and Display calculated data in section data.
Precautions for use
1. The detection angle of the radar flow velocity sensor is 40 to 60 degrees. The detection angle refers to the angle between the radar antenna plane of the flow velocity sensor and the horizontal plane. In some environments with uneven water flow in rivers, large angles are easy to jump, and the installation angle is too high. The smaller, the better the suppression of rainfall interference. DJI's Polit software provides a one-click positioning button to restore the gimbal detection angle to 45°.
2. The flight height is recommended to be within 10-20 meters from the water surface for optimal detection accuracy.
3. If there are strong reflective obstructions such as water and metal in the radar emission direction, it will affect the radar test effect.
