Equipment for automatically and precisely controlling spraying of crop chemical treatment agent based on unmanned aerial vehicle

Abstract

The invention discloses equipment for automatically and precisely controlling spraying of a crop chemical treatment agent based on an unmanned aerial vehicle. The equipment comprises a chemical treatment control spraying machine, a visible-near infrared crop nitrogen photoelectric measuring instrument, a chemical treatment agent flow self-air-conditioning adjusting instrument, a chemical treatment agent storage box, a piezoelectric radar distance monitoring instrument, a self-control system, an accumulator and an unmanned aerial vehicle control signal receiver; output ends of the visible-near infrared crop nitrogen photoelectric measuring instrument, the unmanned aerial vehicle control signal receiver and the piezoelectric radar distance monitoring instrument are all electrically connected with an input end of the self-control system; an output end of the self-control system is electrically connected with an input end of the chemical treatment agent flow self-air-conditioning adjusting instrument; the chemical treatment agent in the chemical treatment agent storage box is uniformly sprayed through the chemical treatment agent spraying machine after passing through the chemical treatment agent flow self-air-conditioning adjusting instrument; and the accumulator supplies power to the equipment. The equipment achieves such purposes as high yield, agent saving and protection of farmland ecological environment through realization of automatic and precise area-spraying of the chemical treatment agent.

Description

Technical field [0001] The invention relates to the field of agricultural machinery, and in particular to a drone-based device for automatically and accurately regulating and spraying crop chemical control agents. Background technique [0002] At present, with the development and application of the drone industry in the field of agricultural technology, it has become an inevitable trend in the development of modern agriculture to control the growth of crops with chemical reagents in order to increase the yield and adjust the physiological status of crops during the planting process. . In the process of spraying chemical control agents by drones, uneven planting density, soil nutrient fertility and uneven fertilization in the later period caused by crop growth and human factors during the planting process caused uneven crop growth and fertility. Problems such as uneven nutrient supply. The main purpose of drones to spray chemical control agents on crops is to spray chemical cont...

AI Technical Summary

Problems solved by technology

[0004] (1) Most of the existing UAV plant protection applications are used in image information collection, pest crop identification instruments, etc. to complete some flight operations, and manually complete some decisions through the collected pest picture information, which can only play a role A monitoring function, but cannot achieve real-time monitoring and feedback, and requires manual manipulation to confirm crop information, and it is difficult to meet the level of automation requirements

[0005] (2) Most of the existing UAV plant protection applications are based on human experience to control the spraying of chemical control agents. During the operation process, regional real-time monitoring and feedback of crop information cannot be carried out, and the entire process is uniform. As a result, it is impossible to realize regional precise variable spraying

The actual application cannot meet the requirements of the current crop growth status, and the UAV developed by us is equipped with equipment for automatic and precise control of spraying crop chemical control agents, which is used in the automatic and precise control of crops. Real-time detection and feedback to complete the precise spraying of chemical control agents

[0006] (3) At present, most of the UAVs used in plant protection use gasoline engine power systems. Due to the weight of the body itself, it is difficult to meet the requirements of UAV flight. The impact of the weight of the airframe greatly shortens the flight efficiency and endurance time, the reaction time is too long, the expected work efficiency cannot be achieved, and the work progress will be affected
