Navigate：Do you know these sensors for UAV atmospheric monitoring?
How did the drone originally conduct atmospheric environmental monitoring?
As China's air pollution situation has become more and more serious in recent years, especially the proportion of smog (particulate matter PM2.5, PM10, etc.) in pollutants is getting heavier and heavy, so the task of air pollution detection and treatment in China is also More and more heavy. The state has also deployed or improved particulate matter and gas detection equipment in most cities, forming a ground pollution source detection network with a dense distribution of national control points.
However, we can also clear that there is still a big gap between the predictions made based on the ground control data of the national control points and the actual environmental pollution situation. In addition, the management methods implemented according to the ground monitoring data, such as ground sprinkling, construction Site coverage, traffic restrictions, industrial production limits, boiler renovation, desulfurization and denitrification treatment, etc., the results are not satisfactory.
As the third-generation remote sensing technology after aerial and aerospace remote sensing, the UAV remote sensing technology has the advantages of stereo monitoring, fast response, wide monitoring range and small topographic interference. It is the future identification and concentration monitoring of atmospheric emergencies. One of the important development directions.
However, due to the limited load of the drone. High-precision sensor loading is required to perform high-precision atmospheric environmental monitoring. Traditional sensors often have limited choices in terms of size and weight. therefore. Research and development of small size suitable for drones. Light sensor load to achieve UAV air pollution monitoring, drone fixed pollutants.
Second, the UAV gas detection load characteristics
● The software can support multiple drone manufacturers including all series in DJI.
● Thousands of gas sensors can be replaced at any time, and the system has automatic identification.
●The shell is waterproof, windproof, dustproof and anti-collision design
● Display monitoring data in real time and generate corresponding trend curves.
● View historical real-time data, and generate curve analysis graphs at the same time. List and chart styles display historical data for easy comparison.
● Simultaneous display of latitude and longitude, altitude, aircraft status, temperature, humidity, PM1, PM2.5, PM10, real-time concentration values of thousands of gases.
● Detection accuracy can reach ppb level.
● Real-time wireless transmission of data to the ground, or real-time transmission to the server via GPRS.
Third, the application market
The standard monitoring parameters of the UAV atmospheric monitoring system include: carbon monoxide, sulfur dioxide, nitrogen dioxide, ozone, volatile organic compounds and particulate matter PM2.5, PM10, etc.; the drone will collect data after flying to the target location, and will collect The data is transmitted to the ground data processing system for processing analysis via GPRS.
The UAV atmospheric monitoring system mainly includes unmanned aerial vehicles, gas detection sensors, digital transmission/GPRS, ground station/server, and data processing software.
The sensor component detection methods of the monitoring module mainly include electrochemical detection (measuring conventional gases such as SO2, CO, NO2, and O3), photoelectric particle detection (measuring VOCs, etc.), and laser scattering detection (measuring PM2.5, PM10, etc.).
The UK's alphansense sensor recommended by ISweek is dedicated to the introduction of ambient air quality sensors for atmospheric monitoring, including the toxic gas sensor A4/B4 series, the PID sensor PID-AH and the PM2.5, PM10 particulate sensor OPC-N3. It has been widely used in the field of atmospheric monitoring.
