主　　题：Automation Single Chip Microcomputer Apple Grading Convolutional Neural Network Air Jets 

摘      要：The grading judgment for apples is related to a variety of factors including,size,shape,color,texture,and *** manual sorting methods are time consuming and labor *** addition,the accuracy of the method is easily subjective,not repeatable,error-prone,and affected by the sorting *** paper presents a complete and automated grading system for *** system uses a single-chip microcomputer as the controller of the system,and a PC as the graphics processing *** also includes a conveyor,drive motor,frequency converter for motor control,photoelectric sensors,air compressor,and air jets for ejecting the graded *** classification algorithm is implemented by using a convolutional neural network(CNN).In order to eliminate contact damage of apples,the system specifically uses air jets as actuators to eject the graded apples into the corresponding *** the same time,in order to ensure that an apple triggers the correct ejecting actuator,this paper designs a jet controller with proper logic.
