Indoor test device and test method for dynamic spray deposition measurement of plant protection unmanned aerial vehicle

Abstract

The invention discloses an indoor test device and a test method for dynamic spray deposition measurement of a plant protection unmanned aerial vehicle, and solves the problem of low precision of droplet deposition test data in the prior art. According to the indoor test device for dynamic spray deposition measurement of the plant protection unmanned aerial vehicle, a lifting frame is arranged on a test bed, a sliding mechanism is arranged on the lifting frame, an adjustable nozzle assembly is arranged on the sliding mechanism, and a flow sensor is arranged on the adjustable nozzle assembly; the adjustable spray head assembly is connected with a liquid storage tank arranged on the test bed through a hose; a pushing bedplate used for containing crops is arranged in the test bed, and a laser radar is arranged on the pushing bedplate. According to the dynamic spray deposition measurement indoor test method, not only can the spray width and spray field distribution data of the plant protection unmanned aerial vehicle at different speeds be obtained, but also the influence data of the environment (wind power and temperature) on the spray deposition amount can be obtained, the test is simpler and more visual, and accurate data support is provided for spray of the plant protection unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the technical field of indoor spray testing of unmanned aerial vehicles, in particular to an indoor testing device and a testing method for dynamic spray deposition measurement of unmanned aerial vehicles for planting and protection. Background technique [0002] Multi-rotor plant protection drones have been widely used in the field of agricultural pesticide application. In order to ensure the spraying effect, the multi-rotor plant protection UAV needs to properly adjust the nozzle spacing and select appropriate operating parameters (working height and working speed) before the spraying operation. However, the evaluation of the spray system structure, the uniformity of spray width and droplet distribution, and the selection of operating parameters of multi-rotor plant protection UAVs have always been the hot and difficult research points. Therefore, the accurate evaluation of the performance indicators related to the applicati...
