Embodiment 1

[0025] see figure 1 , in an embodiment of the present invention, a drone system for precise spraying, including a drone controller 100 for sending, receiving and processing information, collecting steering gear information, and controlling the corresponding actions of the steering gear according to the instructions of the drone controller 100 The steering gear information module 101, the wireless communication module 106 for realizing communication with the remote controller 107 and the background command center 108, here, the steering gear information collected by the steering gear information module 101 includes the gyro signal 1011, the course signal 1012, the course deviation Angle signal 1013 and motor signal 1014, according to the above information, the drone can maintain a stable and precise flight, which is also a prerequisite for precise spraying. In this embodiment, the remote controller 107 can realize the process operation of the drone through the wireless communic...

Embodiment 2

[0027] see figure 1 , in the embodiment of the present invention, on the basis of embodiment 1, an unmanned aerial vehicle system for precise spraying also includes a GPS positioning system for locating the current position of the unmanned aerial vehicle, which can be used with a pre-made job prescription Maps are compared to guide the UAV to fly at the starting position or along the set route. Of course, in order to improve the accuracy of positioning, the drone controller 100 is also connected with a panoramic camera 104, which can photograph the current environment of the drone and compare it with the terrain information in the operation prescription map. Yes, at the same time, with the GPS positioning system, it can accurately locate the position of the drone.

Embodiment 3

[0029] see figure 1 , in the embodiment of the present invention, on the basis of embodiment 2, an unmanned aerial vehicle system for precise spraying also includes a liquid level for detecting the liquid level in the medicine barrel electrically connected with the unmanned aerial vehicle controller 100 Sensor 112, which can accurately detect the liquid level in the medicine tank and feed back the medicine dose in time. Of course, after the medicine dose is used up, it can send a signal to the UAV controller 100, and the UAV controller 100 can mark the position Then return to the voyage to add medicine.

Abstract

The invention discloses an unmanned aerial vehicle system capable of accurately spraying, and belongs to the technical field of crop plant protection. The system comprises an unmanned aerial vehicle controller used for receiving, transmitting and processing information, a steering engine information module used for collecting steering engine information and controlling corresponding motions of a steering engine according to commands of the unmanned aerial vehicle controller, and a wireless communication module used for being in communication with a remote control device and a background command center. Before pesticide spraying operation, the system can determine the pesticide applying amounts of corresponding areas according to states of crops on the ground, the pesticide applying amountsare associated with areas needing to be applied with pesticide, and an operation prescription map comprising areas, terrains and pesticide applying amounts is generated and taken as the guidance of later spraying operations. In the spraying process, the flight height, the air line, the flight speed, the switching quantity of an electromagnetic valve of a pesticide outlet pipe and the like can becorrected by the system according to the scene state, images of a panorama camera and a built-in GPS locating system are cooperatively utilized for achieving accurate locating of an unmanned aerial vehicle, and accurate spraying of the unmanned aerial vehicle is achieved in the operation process.

Description

technical field [0001] The invention relates to the technical field of plant protection, in particular to an unmanned aerial vehicle system for precise spraying and a control method thereof. Background technique [0002] With the development of science and technology, the traditional agricultural production mode is gradually replaced by mechanization and informatization. The use of drones for low-altitude operations has the characteristics of flexible use, small size, and low cost, which can greatly improve the efficiency of agricultural and forestry vegetation flying operations. efficiency and precision. At present, the domestic unmanned light and small aircraft industry for agricultural use is in the research and preliminary trial stage, and my country's agricultural aviation technology is still in its infancy. [0003] The use of drones for pesticide spraying has gradually gained more and more attention. However, due to the complexity of the operation and the variabilit...
