Brief introduction of atmospheric environment remote sensing detection system:
With the development of society and economy, the increase of industrial automation, accompanied by the increasing number of motor vehicles and various industrial enterprises on the road, has led to serious emissions of various harmful gases. The environmental pollution caused by various harmful gases and smog PM2.5 has already appeared very intuitively to everyone, causing great harm to human travel and physical health. Therefore, the governance of the atmospheric environment is urgent. In order to improve the level of air pollution detection and improve detection methods, as early as the 1980s, drones have already shown their initial application in industries such as environmental protection, industrial security and forest fire prevention. With the continuous updating and development of related technologies, its flexibility, easy accessibility, safety and rapidity play an increasingly important role in these areas, and it is the most important and efficient method for air pollution monitoring.
The system is mainly a system combining a drone and a gas monitor. It can monitor: SO2, NO2, O3, CO, CO2 and particulate matter PM2.5, PM10, VOCs, etc., and transmit it back to the ground in real time to display the detection data of the environment where the drone is flying and generate the corresponding trend curve. At the same time, it can expand the detection of hundreds of gas parameters such as NH3, HCN, HCL and methane / non-methane hydrocarbons through the configuration of a high-precision, small and lightweight intelligent gas sensor. It can be perfectly mounted on a drone to detect and Man-machine flight has no effect. It also has the advantages of strong portability and high cost performance, which is very suitable for multi-point placement.
First, fast and efficient
For emergencies, drones can immediately monitor a large area of the monitoring area, and the daily monitoring capacity of a single drone can reach a maximum of 200 ~ 320 square kilometers. Monitoring results can generate a variety of thematic data such as high-resolution image data and gas concentration trend curves in a short time. After the occurrence of a pollution accident, it can quickly provide estimates of the changes in pollution status and release them for decision-making.
Intuitive and comprehensive
The high-definition images generated by the drone can visually identify pollution sources, polluted mouths, visible floating objects, etc., and generate distribution maps to provide a basis for environmental assessment and environmental monitoring. The generated multispectral image can monitor the quality of the atmospheric environment intuitively and comprehensively, thereby achieving the purpose of monitoring atmospheric pollutants. The results can demonstrate the state of the atmospheric environment intuitively and comprehensively, and monitor and warn the extent and scope of the impact of pollutants, so as to provide support for the treatment and disposal of atmospheric pollution accidents.
3. Large-scale and macroscopic
UAVs can achieve high-space and large-area monitoring through different flight heights, as well as low-space and small-area accurate monitoring. It can also monitor multiple tens of thousands of square kilometers at the same time. Through multi-spectral analysis, various monitoring data of large-area measurement areas are obtained, and surface information is combined with traditional point information to provide a basis for macro-environment assessment of the entire measurement area. Through comprehensive display of the environmental status of the survey area, the extent and scope of pollutants in the survey area, it provides a demonstration for relevant departments' decision-making.

7. Simultaneously display latitude and longitude, altitude, aircraft status, temperature, humidity, PM1, PM2.5, PM10, real-time concentration values of thousands of gases.
System structure and working principle:
This system mainly includes unmanned aerial vehicle, gas detection, data transmission / GPRS, ground station / server, data processing software and other components. The main role is to detect the atmospheric air quality AQI and emergency detection of toxic and harmful gases, and its accuracy can reach 1PPB. Changing the traditional fixed point detection makes gas detection flexible, fast, accurate and convenient.
The software for gas concentration data acquisition has rich gas types, ranges, and precisions for gas detection. In order to simplify the user's operation and cost, the company specially designed a set of imported high-precision series gas sensors. With a complete set of software information system, it can effectively separate all the detected gas types to achieve all intelligent identification systems. Customers can match different sensors according to different detection scenarios; making the drone gas detection flexible and not affected by the load.
According to the communication method of the imported gas sensor, analog voltage, analog current, TTL, and RS485 can be used. Standard products use two communication modes: RS485 and TTL.
