Design and Implementation of Automatic Sorting Control System for Melon and Fruit Products

Abstract

Melon and fruit sorting system is mainly used in the agricultural field, can be sorted according to the size of melon and fruit, thus improving the efficiency of melon and fruit sorting. The system is mainly composed of controller, conveyor belt conveyor system, weight measurement system, fruit position detection system, fruit selection system and so on. In the system, the SCM STM32F103C8T6 is used as the main controller, and the M1 card is brushed on the reader to identify the kinds of fruits. After confirmation, the corresponding fruits are put on the tray of the weighing sensor to measure. The processor processes and judges the measured values, completes the classification of large, medium and small, controls the corresponding LED indicator lights, indicating that the melons and fruits belong to the same category. Which kind of size, at this time the conveyor belt motor start, and then pick up the analog melon and fruit on the conveyor belt, after infrared probe detection object trajectory, to the melon and fruit transmission to the size of the corresponding position, DC motor stopped running, the corresponding LED indicator lights, complete the transmission of melon and fruit classification. Repeat execution to achieve the purpose of sorting. The experimental results show that the automatic sorting system can distinguish the size of melons and fruits according to the weight of melons and fruits, achieve more accurate sorting effect, fast speed, small error, and can be applied to actual production.
