Description

technical field [0001] The embodiments of the present invention relate to the technical field of aerial pesticide application, and more specifically, relate to a monitoring system and method for the drift trend of aerial pesticide liquid mist cloud clusters. Background technique [0002] In the process of aerial spraying, the atomization degree of the chemical liquid directly affects the effect of the spraying operation and the drift of the droplet cloud. The spray drift is the phenomenon that the spray exceeds the spraying area due to the action of the airflow during the spraying process. The drift of fog droplets and clouds directly affects the pesticide pollution in the surrounding environment of the spraying area. During aerial spraying, the fog droplet cloud is easily affected by environmental factors such as crosswinds and drifts, which becomes a potential way of environmental pollution, destroys water resources and ecosystems, and poses a certain threat to the health ...

Problems solved by technology

Among them, the design of the fog droplet cloud deposition sensor can quickly obtain the amount of fog droplet cloud deposition during the spraying process. Compared with the traditional method of using water-sensitive paper, it can greatly reduce manpower and material resources. However, only through the deposition detection is still unable to respond The overall drift of the fog droplet cloud during the spraying process; and the use of infrared radiation for spray distribution and drift telemetry can realize long-distance spatial monitoring and reflect the overall drift of the fog droplet cloud. However, due to the relatively complicated operation of the equipment used and High environmental requirements are not conducive to the widespread use of this technology

[0005] Therefore, in the current process of real-time monitoring of the drift and diffusion of aerial spraying liquid, there are problems that the overall drift of the fog droplet cloud during the spraying process cannot be reflected in real time or the operation of the equipment is relatively complicated and has high environmental requirements.
