Example Embodiment

[0026] The technical scheme of the present invention will be further explained below in conjunction with the drawings;

[0027] Such as figure 1 , figure 2 , image 3 As shown, the intelligent spray system based on the pressure nozzle of the plant protection drone is composed of a spray device and a control system;

[0028] The spraying device is composed of a medicine box 1, a water pump 2, a medicine pipe and a spray head. The medicine box 1 is provided with two partitions 2 dividing the medicine box 1 into three independent medicine distribution boxes, and the medicine box 1 is arranged in the middle. The volume of the medicine distribution box at the site is several times the volume of the two ends of the medicine distribution box. The lower ends of the medicine distribution box are respectively connected to the inlet of the water pump through a pipe, and the outlet of the water pump is respectively connected to the three nozzles of the four-way pipe 4, The remaining nozzle o...

Abstract

The invention relates to an intelligent sprinkling system and method based on plant-protecting unmanned aerial vehicle pressure-type spray heads. The intelligent sprinkling system comprises a sprayingdevice and a control system. The spraying device consists of a pesticide tank, a water pump, a pesticide pipe and spraying heads. The control system consists of an inertial measurement unit, a mastercontrol circuit and a water pump driving circuit. The inertial measurement unit comprises an attitude sensor U1 for measuring the acceleration speed of a plant-protecting unmanned aerial vehicle, themaster control circuit comprises a master control chip U2, and the flight speed of the aerial vehicle is obtained by receiving the acceleration speed data of the attitude sensor U1 through time integration. The water pump driving circuit consists of a relay group RE1 and a water pump set. The intelligent sprinkling system and method based on plant-protecting unmanned aerial vehicle pressure-typespray heads achieves liquid pesticide concentration control by spraying different concentrations of pesticide at an acceleration stage, makes pesticide spraying uniform and improves the operating efficiency.

Description

Technical field [0001] The invention relates to a spraying system of a plant protection drone, in particular to an intelligent spraying system based on a pressure spray head of a plant protection drone, and the invention also relates to a spraying method. Background technique [0002] Through countless field and ground flight control operations, it has been found that the spraying of liquid medicine during the acceleration and deceleration phases of the aircraft is extremely uneven. At the same time, referring to the existing solutions, most of the existing solutions are to turn off the pump during these two phases, and finally complete the sweep. side. Although this scheme controls the damage caused by pesticides to crops, it increases time costs and reduces operating efficiency. [0003] The spraying speed of the existing plant protection drones cannot be effectively adjusted with the speed of the aircraft during the acceleration and deceleration phases, resulting in a large inc...
