Description

Technical Field

[0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to an intelligent unmanned aerial vehicle. Background Art

[0002] Plant protection drones are unmanned aircraft used for agricultural and forestry plant protection operations. Compared with traditional manual plant protection methods, plant protection drones can complete large-scale farmland spraying operations in a short period of time, greatly improving work efficiency. For example, a plant protection drone can complete the spraying tasks of hundreds or even thousands of acres of farmland every day, while manual spraying may only be able to complete a few acres to more than ten acres a day. In addition, drones are equipped with advanced sensors and nozzle control systems, which can achieve precise pesticide and fertilizer spraying. The dosage and range of spraying can be adjusted according to different crop types, growth stages and pest and disease conditions, reducing pesticide waste and environmental pollution. For example, the plant protection drone proposed in patent announcement number CN107054658B.

[0003] When operating, existing plant protection drones usually carry pre-mixed pesticides and fly over farmland for spraying. However, affected by factors such as terrain, soil conditions and vegetation coverage, the distribution of pests in farmland is often uneven. For example, areas close to water sources, in low-lying areas or in grassy areas beside fields are more likely to breed pests, and their pest density is relatively high; while in places with higher terrain and drier soil, the number of pests may be relatively small, but the concentration of pesticides sprayed by plant protection drones is fixed, which may lead to insufficient pesticide dosage in places with high pest density, thus failing to effectively kill pests; while in places with low pest density, fixed concentrations of pesticides may lead to excessive use, which will not only waste pesticide resources, but also cause unnecessary pollution to the environment.

[0025] The operating principle of the present invention is now explained as follows: the aqueous solution and the drug solution are respectively injected into the water storage chamber 10 and the drug storage chamber 11 through the infusion tube 13, and then the operator controls the rotation of the rotor 2 of the body 1 through the control handle, thereby controlling the body 1 to take off and making the body 1 fly above the farmland. Then the operator transmits a control signal to the PLC controller 3 on the surface of the body 1 through the control handle. After receiving the electrical signal, the PLC controller 3 first controls the high-resolution camera 6 to work. The high-resolution camera 6 can take clear images of crops, and analyze the color, shape, texture and other characteristics of the leaves through image recognition technology to identify possible signs of pests and diseases. For example, leaves bitten by pests will have gaps, discoloration, etc., and leaves infected with diseases may have spots, withering, etc. The drone transmits the collected images to the ground control station or the cloud in real time. Server (the ground control station or cloud server uses artificial intelligence and machine learning algorithms to train a large amount of pest and disease data in advance, establishes a pest and disease identification model, inputs the data collected by the drone into the model, conducts rapid analysis and judgment, and determines the type and severity of the pest and disease. The ground control station or cloud server establishes a rich pesticide formula database in advance, which includes the types, concentrations and proportioning methods of pesticides required for different types of pests and diseases. According to the pest and disease results analyzed by the drone, the appropriate pesticide formula is automatically selected from the database. This is an existing mature technology and will not be repeated in this article), the ground control station or cloud server transmits the formula of the appropriate pesticide ratio to the PLC controller 3, and the PLC controller 3 controls the water pump 55 and the drug pump 16 to work simultaneously. The water pump 55 and the drug pump 16 are both metering pumps, so that an appropriate amount of aqueous solution and drug solution can be delivered to the mixing chamber 12; Then the PLC controller 3 controls the stirring motor 35 to work, and the stirring motor 35 drives the stirring frame 54 to rotate, and the stirring frame 54 is used to mix and stir the aqueous solution and the liquid medicine, and then the PLC controller 3 controls the UAV to fly in the area photographed by the high-resolution camera 6 (for example, the high-resolution camera 6 has a single shooting range of ten meters, and the high-resolution camera 6 has an angle adjustment function, which can shoot pests in a certain range. The PLC controller 3 will control the UAV to fly ten meters and continue to repeat the above steps, detect the pests in another ten-meter length range, and mix pesticides of different concentrations), and at the same time, the PLC controller 3 controls the high-pressure pump 7 to work, and the high-pressure pump 7 transports the stirred pesticide in the mixing chamber 12 to the square tube 172, and transports it to the vertical pipe 20 through the rotating pipe 19, and then sprays it out through the nozzle 21; When the body 1 is flying at high altitude and the wind sensor 18 detects strong wind, the wind sensor 18 will transmit an electrical signal to the PLC controller 3. After receiving the electrical signal, the PLC controller 3 will detect the wind direction through the wind direction sensor 171. Then, the PLC controller 3 drives the control motor 27 to rotate to a set angle according to the electrical signal transmitted by the wind direction sensor 171. The control motor 27 drives the sliding plate 25 to move through the mutual engagement of the driving gear 28 and the tooth plate 26. The sliding plate 25 controls the simultaneous rotation of multiple rotating tubes 19 through the mutual engagement of the lower tooth plate 26 and the gear ring 22. The rotating tube 19 will drive the vertical tube 20 and the nozzle 21 to rotate, so that the vertical tube 20 and the nozzle 21 rotate to a set angle (for example, if the wind force is level three and the wind direction is north wind, the PLC controller 3 will control the vertical tube 20 and the nozzle 21 to rotate thirty degrees toward the wind direction, and the PLC controller 3 will control the UAV to fly along the wind direction), so that the pesticides are sprayed in the farmland as much as possible to reduce pesticide pollution elsewhere; When the nozzle 21 is clogged, the spraying speed of the nozzle 21 will be greatly reduced, so that the hydraulic pressure in the side vertical pipe 20 will rise rapidly, and the water pressure in the elastic waterproof bag 33 will rise rapidly. The elastic waterproof bag 33 will drive the lifting plate 32 to overcome the elastic force of the upper spring and move upward, so that the lifting plate 32 squeezes the trigger switch 34 above, and the trigger switch 34 will send an electrical signal to the PLC controller 3. After receiving the electrical signal, the PLC controller 3 will control the micro-electric push rod 56 to reciprocate three times, and the micro-electric push rod 56 will continuously squeeze the lifting plate 32 below, and the lifting plate 32 will drive the pin 30 to move downward and insert into the nozzle 21, and use the bristles 31 to clean the impurities accumulated in the inner hole of the nozzle 21; When the fuselage 1 collides with a bird during flight and loses balance and falls, the gyroscope inside the fuselage will detect this situation, and the gyroscope will send an electrical signal to the PLC controller 3. After receiving the electrical signal, the PLC controller 3 immediately controls the solenoid valve 43 to open, and the compressed gas inside the high-pressure gas tank 41 will be transported to the annular cavity 40 through the connecting pipe 42, and then transported to the storage box 361 through the short pipe 44. The gas transported to the annular cavity 40 will push the guide plate 37 upward, so that the connecting rod 39 under the guide plate 37 is disconnected (the connecting rod 39 is made of plastic and has a diameter of The guide plate 37 is thinner), and the guide plate 37 will rotate upward along the hinge to open under the impact of the airflow, and the direction of the guide plate 37 is limited under the push of the top rod 45, and the guide plate 37 is adsorbed by the magnet 46 to keep the guide plate 37 in a vertical state, and the small parachute 362 inside the storage box 361 will detach from the storage box 361 under the impact of the airflow, and will open under the action of the airflow, and under the action of the small parachute 362, the body 1 will slowly descend, thereby avoiding the problem of damage to components caused by the excessive descent speed of the body 1, and extending the service life of the body 1.
