An indoor test platform and detection method for plant protection drone spraying

Abstract

The invention discloses a plant protection unmanned aerial vehicle indoor test platform. The plant protection unmanned aerial vehicle indoor test platform comprises a base frame, a rotating shaft, a fixed bracket, sliding frames, distance measuring instruments and a liquid level collecting device; the base frame comprises a base block and supporting rods which are fixedly arranged on the base frame; the rotating shaft is detachably arranged on the supporting rods of the base frame, and is provided with a body; the body is arranged on the rotating shaft in a sleeving manner to form a whole body; the fixed bracket is arranged on the base frame through the rotating shaft; the sliding frames are arranged on the body at equal intervals; a sliding groove is formed in the bottom of each sliding frame; the distance measuring instruments are arranged in the sliding grooves; the liquid level collecting device is arranged at the top of the base frame and is connected with the supporting rods through the rotating shaft and a hanging rope; the height of a plant protection unmanned aerial vehicle can be adjusted; the pitch angle of the unmanned aerial vehicle can be adjusted precisely, so that the pitch angle of the unmanned aerial vehicle is consistent with that in actual flight; a better detecting result is obtained; a plant protection unmanned aerial vehicle indoor test method is also provided; the position and azimuth angle information of the plant protection unmanned aerial vehicle are measured through the distance measuring instruments; through the liquid level connecting device, the plant protection unmanned aerial vehicle spraying droplet distribution data are acquired, the error introduced by the liquid level collecting device is calculated and corrected, and the spraying droplet distribution probability is obtained.

Description

technical field [0001] The invention relates to the field of agricultural plant protection drones, in particular to a spraying test platform for plant protection drones and a spraying detection method for drones. Background technique [0002] Rotary-wing plant protection UAV is a new plant protection device in recent years. There are few reports on the indoor test platform and equipment of plant protection UAV. The speed and the height of the drone are used to simulate the actual flight process of the plant protection drone, but because the plant protection drone is fixed on the guide rail, its pitch angle cannot be adjusted, and the actual flight process of the plant protection drone cannot be completely simulated. Secondly, there is no The droplet deposition detection is described, and in the existing data, there is no mention of how to reduce the impact of the ground effect of the plant protection drone on the test results during the detection process.
