[0033] With the rapid development of drone technology, spraying drones have begun to appear for spraying pesticides on crops. These drones are not only used for spraying pesticides but can also perform various tasks such as firefighting and defogging, meeting diverse needs and improving production efficiency. However, compared to manned aircraft, agricultural spraying drones cannot manually control the timing and amount of pesticides applied. Excessive or insufficient pesticide application is detrimental to crop growth and fails to improve agricultural production efficiency.

[0034] The drone spraying system in the relevant technology has a technical problem that the spraying volume cannot be adjusted during use.

[0035] Please refer to Figures 1-2 This embodiment provides a drone, which includes a fuselage and a drone spraying control system, the latter being mounted on the fuselage. This drone effectively improves upon the aforementioned technical problems, enabling automatic adjustment of the spraying volume and making spraying more convenient and intelligent.

[0036] Please refer to Figures 1-2 This embodiment provides a drone spraying control system including an air source module 10, a spraying module 20, a first solenoid valve 30, and a control module. The spraying module 20 is connected to the air source module 10 and is filled with liquid medicine. The first solenoid valve 30 is located in the spraying module 20 and is used to connect or disconnect the spraying module 20. The control module is connected to the air source module 10, the spraying module 20, and the first solenoid valve 30. The control module is used to control the start and stop of the air source module 10 and the first solenoid valve 30 according to the drone's flight information, thereby adjusting the spraying volume of the spraying module 20.

[0037] Specifically, existing drone spraying systems cannot adjust the spray volume during use; too much or too little spray will affect the final production results. Therefore, to solve this technical problem, the drone spraying control system provided in this embodiment provides the necessary air supply medium to the spraying module 20 via the air source module 10. The control module controls the opening and closing of the first solenoid valve 30 of the spraying module 20 based on the drone's flight information, thereby adjusting the spray volume and achieving automatic adjustment of the spray volume. This makes spraying more convenient and intelligent.

[0038] In this embodiment, the control module can detect the latitude, longitude, speed, and altitude of the UAV, and control the operation of the spraying module 20 based on the flight information such as latitude, longitude, speed, and altitude, thereby realizing automated spraying operations.

[0039] Specifically, there are multiple spraying modules 20, and the first solenoid valve 30 is connected to multiple spraying modules 20 simultaneously. Each spraying module 20 is filled with a different liquid pesticide. This allows the drone to complete multiple spraying tasks during a single flight. In this embodiment, there are three spraying modules 20. In other embodiments, the number of spraying modules 20 can be increased or decreased according to actual conditions, and no specific limitation is made here.

[0040] It should be noted that the spraying module 20 includes a spraying mechanism 21, a medicine tank 22, and a nozzle 23. The spraying mechanism 21 is connected to both the first solenoid valve 30 and the nozzle 23, while the medicine tank 22 is connected to the spraying mechanism 21. The medicine tank 22 can be filled with different liquid medicines, and the spraying mechanism 21 can output a proportional amount of liquid medicine to the nozzle 23, which then sprays the medicine outwards.

[0041] In this embodiment, the nozzle 23 is an atomizing nozzle 23. The atomizing nozzle 23 can disperse the sprayed liquid, thereby expanding the spraying area and achieving more efficient spraying operations.

[0042] It should also be noted that the spraying module 20 further includes a flow sensor 26, which is connected to the nozzle 23 and the control module. The flow sensor 26 is used to detect the spraying flow rate of the nozzle 23. The control module uses the flow rate information of the nozzle 23 fed back by the flow sensor 26 to determine the spraying volume of the spraying module 20.

[0043] Furthermore, the drone spraying control system also includes a pressure control valve 25, which is located on the spraying mechanism 21 and is used to regulate the pressure of the cold air entering the spraying mechanism 21.

[0044] Furthermore, the spraying module 20 also includes a one-way valve 27, which is located in the medicine tank 22. The one-way valve 27 ensures that the medicine in the medicine tank 22 enters the spraying mechanism 21 in one direction, thereby preventing the medicine in the spraying mechanism 21 from flowing back into the medicine tank 22.

[0045] In this embodiment, the UAV spraying control system further includes a pressure reduction module 50, which is connected to the air source module 10 and used to adjust the pressure of the air source module 10. Specifically, the pressure reduction module 50 is a pressure reducing valve, which adjusts the pressure of the air source module 10 to the rated working pressure of the spraying system.

[0046] Furthermore, the drone spraying control system also includes a first pressure sensor 40, which is disposed in the air source module 10 and is used to detect the pressure of the air source module 10. This allows the system to determine whether the pressure of the air source module 10 has reached the rated operating pressure of the spraying system.

[0047] In this embodiment, the gas source module 10 is a cold air cylinder.

[0048] Furthermore, the drone spraying control system provided in this embodiment also includes a second solenoid valve 24. Each spraying module 20 is equipped with a second solenoid valve 24, and the control module controls multiple spraying modules 20 individually through the second solenoid valve 24.

[0049] The drone spraying control system provided in this embodiment also includes a second pressure sensor 28 and a third pressure sensor 60. The second pressure sensor 28 is disposed in the spraying module 20 and is used to detect the overall pressure of the spraying module 20. The third sensor is disposed in the spraying mechanism 21 and can detect the pressure of the spraying mechanism 21.

[0050] The drone spraying control system and drone provided in this embodiment have at least the following advantages:

[0051] Existing drone spraying systems cannot adjust the spray volume during use; excessive or insufficient spraying will affect the final production results. Therefore, to solve this technical problem, the drone spraying control system provided in this embodiment provides the necessary air supply medium to the spraying module 20 via the air source module 10. The control module controls the opening and closing of the first solenoid valve 30 of the spraying module 20 based on the drone's flight information, thereby adjusting the spray volume and achieving automatic adjustment of the spray volume. This makes spraying more convenient and intelligent.

[0052] In summary, this utility model embodiment provides a drone spraying control system and a drone. The drone spraying control system includes an air source module 10, a spraying module 20, a first solenoid valve 30, and a control module. The air source module 10 and the spraying module 20 are connected. The spraying module 20 is filled with liquid pesticide. The first solenoid valve 30 is located in the spraying module 20 and is used to connect or disconnect the spraying module 20. The control module is connected to the air source module 10, the spraying module 20, and the first solenoid valve 30. The control module controls the start and stop of the air source module 10 and the first solenoid valve 30 based on the drone's flight information, thereby adjusting the spraying volume of the spraying module 20. In use, the air source module 10 provides the necessary air source working medium to the spraying module 20. The control module controls the start and stop of the first solenoid valve 30 of the spraying module 20 based on the drone's flight information, thereby adjusting the spraying volume of the spraying module 20 and achieving automatic adjustment of the spraying volume. This makes spraying more convenient and intelligent.

[0053] The drone includes a fuselage and a drone spraying control system, with the control system mounted on the fuselage. During operation, the air supply module 10 provides the necessary air medium to the spraying module 20. The control module uses the drone's flight information to control the opening and closing of the first solenoid valve 30 of the spraying module 20, thereby adjusting the spray volume and achieving automatic adjustment of the spray volume. This makes spraying more convenient and intelligent.
