Problems solved by technology

[0002] When plant protection drones spray pesticides on crops, uneven spraying of pesticides often occurs
It is mainly due to three reasons. First, the flight altitude, flight speed and water pump output will all affect the amount of medicine attached to the crops. However, many drones do not integrate the three when operating. Consider, therefore, when the altitude and speed of the aircraft change during acceleration, deceleration or turning, the drug dosage will be uneven
Second, during the spraying process, some nozzles may be blocked, if not found in time, it will cause the crops in blocks to be missed
Third, when the amount of pesticides is low or the airborne pesticides are exhausted, the stop points of pesticides are not recorded in time or are not recorded, resulting in small pieces of crops being missed
These methods cannot make the spraying effect of plant protection drones in a better state when facing different crops

Embodiment Construction

[0044] The preferred technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0045] Such as figure 1 As shown, the control management system and control method of a kind of intelligent plant protection drone of the present invention are used to solve the problem of uneven spraying of plant protection drones when spraying pesticides, and poor consistency of spraying effects when changing job objects question;

[0046]It is mainly composed of two modules: flight control system and intelligent spraying management system. The flight control system includes main control chip A, attitude sensor, differential GPS, barometer, radio data transmission, power and electricity detection module, etc.; the intelligent spraying management system includes: auxiliary control chip B, flow meter, power module, water pump and normally closed electromagnetic Valve (normally closed solenoid valve is divided into six water inle...

Abstract

The invention discloses a control management system for an intelligent plant protection unmanned aerial vehicle and a control method thereof. The system comprises a flight control system for controlling flight of the unmanned aerial vehicle and an intelligent spraying management system for controlling a spraying device. According to a spraying area and a dosage, the number of working nozzles in a sprayer, the pressure of a water pump and the cruising speed are calculated. In comparison with the prior art, the drug in a farmland is more uniformly sprayed, and a drug drip leakage phenomenon is not caused.

Description

technical field [0001] The invention relates to a control management system and a control method of an intelligent plant protection unmanned aerial vehicle, belonging to the technical field of navigation positioning and control. Background technique [0002] When plant protection drones spray pesticides on crops, uneven spraying of pesticides often occurs. It is mainly due to three reasons. First, the flight altitude, flight speed and water pump output will all affect the amount of medicine attached to the crops. However, many drones do not integrate the three when operating. Consider, therefore, at acceleration, deceleration or turning, after the altitude and speed of the aircraft change, the drug dosage will be uneven. Second, during the spraying process, some nozzles may be blocked. If not found in time, it will cause clumps of crops to be missed. Third, when the amount of pesticides is low or the airborne pesticides are exhausted, the stop points of pesticides are not ...
