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 invention relates to a spraying flow control system, in particular to an automatic spraying flow control system and belongs to the technical field of planting. Background technique [0002] With the deepening of agricultural mechanization and modernization, more and more high-tech technologies are used in agricultural planting technology, especially with the development of drone technology, large-scale planting will choose drone spraying technology more , this spraying technology can effectively reduce the impact of topography and other objective factors on the spraying effect, improve planting efficiency, and reduce labor intensity of workers. However, due to the fixed spraying flow rate of the plant protection drone, the flying speed and flying height of the drone are changing, especially for different complex terrains, which will cause uneven spraying density, which will affect the control effect to a certain extent, and the economical use of pe...
