Spraying flow automatic control system

Abstract

The invention discloses a spraying flow automatic control system. The spraying flow automatic control system comprises a GPS module, an IMU module, an ultrasonic module, an air pressure gauge module and an electronic magnetic compass module. Data collected by the GPS module, the IMU module, the ultrasonic module, the air pressure gauge module and the electronic magnetic compass module are fused into inertial navigation data through an inertial navigation correction module. The inertial navigation correction module works out rotation speed data and horizontal speed data for unmanned aerial vehicle running according to the inertial navigation data. The fuselage coordinate system serves as a reference for the rotation speed data and the horizontal speed data. The rotation speed data and the horizontal speed data are input into a flow automatic control module. Spray nozzle spraying output quantity data are generated by the flow automatic control module in a PID control mode and are input into a controllable flow spraying system body. The controllable flow spraying system body controls output connecting spray nozzles. According to a spraying flow automatic control method and the spraying flow automatic control system, the self-adaption problem between the spraying flow and the flying speed is mainly solved, the spraying concentration per unit area is kept to be fixed in real time, and meanwhile, other monitoring functions are achieved for users to refer to.

Description

Technical field [0001] The present invention involves a spray flow control system, which is particularly involved in a spray traffic automatic control system. Background technique [0002] With the deepening of agricultural mechanization and modernization, more and more high -tech technology uses agricultural planting technology, especially with the development of drone technology, large -scale plants will choose more drone spraying technologyThis spray technology can effectively reduce the effects of objective factors such as terrain on spraying effects, improve planting efficiency, and reduce the labor intensity of workers.However, due to the fixed traffic of the plant protection drone spraying flow, the flying speed and flight height of the drone are changed, especially for different complex terrain, which will cause uneven spray density, resulting in a certain extent affecting the prevention and treatment effect.The pesticide residues indicators are unqualified and other cons...
