In this paper, the researchers built a three-dimensional air pollution monitoring system based on a multi-rotor UAV platform, and did research on the system integration technology. (1) Anti-outflow Field interference measures. We used adjustable speed ducted fans to stabilize the airflow, and set the airway to further improve the intake stability and reduce the interference of the flow field around the drone to the measurement equipment. Optimizing the installation location of the equipment according to the CFD simulation results; (2) Anti-electromagnetic interference treatment. By wrapping the electromagnetic shielding cloth (silver fiber fabric) on the measurement module, the electromagnetic interference generated by the UAV’s own device on the sensor module is reduced; (3) Data preprocessing. Before the regional measurement, an airborne control test was carried out, and the data collected by the airborne equipment was corrected using data processing methods. The equipment was equipped with an Internet of Things module and a GPS positioning module, so that the measurement data could be transmitted to the background for analysis in real time. (4) Based on the uniform experimental design method, the UAV inspection points are arranged, and the measurement path of the measurement system is optimized. And carried out on-site measurements in Xi’an, China. |
