Abstract

The present invention relates to an electrostatic topping device and method for precisely regulating the output voltage according to different growth conditions of cotton. The device mainly consists of an image self-identification and processing device, a discharge control device, and a high-voltage electrostatic generator. Its characteristic lies in that the upper computer divides the growth conditions of cotton into three grades, namely good, medium, and poor, designated as A, B, and C, according to the area of the cotton top leaf. During operation, the image self-identification and processing device at the top of the cotton plant automatically identifies and measures the area of the cotton top leaf. The upper computer divides the growth grade of the cotton plant according to the area of the cotton top leaf and transmits an output voltage command to the discharge control device according to the growth condition of the cotton plant. When the growth grade of the cotton plant is A, the discharge control device adjusts the high-voltage electrostatic generator to output a high voltage; when the growth grade is B, a medium voltage is applied; when the growth grade is C, a low voltage is applied. The present invention realizes precise output voltage regulation according to the growth grade of cotton, and while achieving electrostatic topping, reduces the harm of the high-voltage electrostatic field to cotton plants with poor growth.
