An ultrasonic sensor-based device and method for precise target application of crops with wide plant spacing

Abstract

The present invention disclosed a wide -plant -based large -distance crop for target appliances and methods based on ultrasonic sensors. The applied device includes crop detection modules, spray rack height adjustment modules, spray modules, vehicle speed sensors and control modules.The sensor is used to detect the crops; the spray rack height adjustment module is used to adjust the vertical height of the entire spray frame; the spray module includes the pipeline, the medicinal liquid box, the diaphragm pump, the nozzle, and the solenoid valve.The position adjustment can be adjusted by the nozzle adjustment device; the speed sensor is used to monitor the walking speed of the device, and it is connected to the detection module to the control module respectively; the control module uses single chip machines such as STM32.The ultrasonic sensor of the present invention is low, the installation operation is wide, and the range of use is wide. It is especially suitable for seedling crops that are planted far away, which can reduce the amount of pesticides in large quantities;Wide range of applications.

Description

technical field [0001] The invention relates to the technical field of agricultural pesticide application machinery, in particular to a device and method for precise target pesticide application in farmland. Background technique [0002] Pesticide spraying is an important means of crop pest control. The traditional uniform spraying method wastes pesticides and causes a large amount of pesticides to be sprayed onto the surface of the soil around the crops by mistake. High, environmental pollution, food safety and other issues. [0003] In order to solve the above problems, targeted drug application technology has been developed and partially applied. On the basis of identifying the application target, the target application technology adopts an economical and reliable application plan to spray the target area on demand. The method can effectively reduce pesticide waste, reduce environmental pollution and reduce pesticide residues. At present, the target detection methods o...

Problems solved by technology

[0005] The existing technology involves a mechanical device of a field-to-target spraying machine, the height and row spacing of which can be automatically adjusted according to the real-time crop information obtained, but the mechanical structure is complicated, the control is cumbersome, the cost is high, and there is no target detection function. It is impossible to achieve selective targeted application of pesticides; in addition, under normal circumstances, the row spacing of the same crop is basically fixed, and there is no need for automatic real-time adjustment during operation, just adjust it manually before operation

The prior art also relates to a differential boom spray accurate target alignment device and a target detection method, including the use of a ditch ranging sensor and a row ranging sensor, so that the boom sprayer can accurately identify the target during field spraying. And only spray pesticides or liquid fertilizers on the target; but it can only detect the presence or absence of the target, and cannot automatically adjust the height of the nozzle according to the height of the target, and cannot spray accurately on the target
