Device and method for detecting spray droplet deposition uniformity of agricultural drone

Abstract

The invention relates to a device and method for detecting spray droplet deposition uniformity of an agricultural drone. The device comprises one machine frame, an X-directional movement mechanism, aY-directional movement mechanism, a Z-directional movement mechanism, an objective table, a laser ranging module, an array cavity tray container and the other machine frame; in the field of pesticidespraying, the flight height and speed of the drone and the influence of a rotor wing wind field on drifting and depositing of droplets in air can be researched indoors by adopting the detecting deviceand a spray droplet deposition uniformity detecting method provided by the invention; moreover, test space can be saved, and the device and the method have the characteristics of rapidness and intuitiveness.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicle spraying, and in particular relates to a device and method for detecting the deposition uniformity of agricultural unmanned aerial vehicle spray droplets. technical background [0002] Agricultural UAVs are not restricted by geographical factors, and can complete tasks smoothly and efficiently. UAV spraying of medicines and fertilizers is effective and safe, and can reduce the risk of pesticide poisoning of operators. The degree of automation is high, and the operating crew is relatively Less, low labor intensity, so drones have been widely used in agriculture. [0003] In the process of pesticide spraying by UAV, the particle size and coverage density of pesticide droplets have a significant impact on the efficacy of insecticides and fungicides, and the uniformity of droplet deposition affects the efficacy of pesticides. The coverage density can achieve the ideal control effect, and it is ...

Problems solved by technology

[0004] At present, in the field of agricultural drone spraying, the water-sensitive paper detection method is mainly used to detect the droplet density and droplet coverage. The method is to paste the water-sensitive paper on the slide, and place the slide on the crops at a certain distance. In this method, after a period of time after spraying, the slides are collected and sealed in a slide box filled with silica gel particles. After the droplets are fixed, they are scanned and input into the computer. However, this method needs to be carried out in the outdoor field, and the detection error is relatively large. Moreover, the test environment is uncontrollable, resulting in different test results and low repeatability
