A sampling control method, controller and system for unmanned aerial vehicle

Abstract

The invention discloses a UAV sampling control method, a controller and a system thereof. After receiving a first descending instruction sent by a user, the connecting device is controlled to descend, so that the sampling platform descends; wherein, the UAV communicates with the UAV through the connecting device Sampling platform connection; after receiving the first movement instruction sent by the user, read the direction data of the sampling platform according to the target image data of the sampling platform; send the first movement instruction and direction data to the sampling platform, so that the sampling platform can move according to the first The actual moving direction and distance analyzed by the moving instruction and direction data are moved to the preset sampling point position for sampling. The way of flexible control through the sampling platform enables the UAV to control the sampling process and realize safe sampling in complex environments, ensuring the safety of sampling equipment and achieving high-precision sampling.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle sampling, in particular to an unmanned aerial vehicle sampling control method, a controller and a system thereof. Background technique [0002] With the development of science and technology, agriculture and ecological environmental protection, unmanned aerial vehicles (UAVs), as a technological tool with highly adaptable data acquisition advantages, have been widely used in atmospheric environment monitoring, water body sampling monitoring, ecological monitoring, ecological emergency early warning and on-site command, etc. important areas. [0003] Unmanned aerial vehicle sampling can replace traditional manual sampling, and it is not restricted by the geographical environment. It can accurately arrive at the sampling point for sampling, which greatly improves the sampling efficiency. However, at present, UAV sampling usually adopts two methods: UAV carrying a robotic arm or hanging a samp...

AI Technical Summary

Problems solved by technology

Among them, the use of robotic arm sampling control has the advantage of high precision, but it requires the UAV to be close to the sampling target, and in a complex environment, the UAV is easy to touch the surrounding objects, which may cause the UAV to fall or be damaged.

At the same time, the method of hanging the sampling device is adopted. Although the drone does not need to be close to the target, the suspension device is affected by the environment and is easy to swing and rotate. When there is an obstacle above the sampling point, the sampling device is difficult to avoid and is prone to entanglement. The man-machine is trapped or even falls
