Design and development of intelligent citrus grading system

Abstract

In order to reduce the production cost of small-scale farms in China and improve work efficiency, an intelligent grading system for citrus grading was designed. The system combines the synchronous belt with the fruit pallet to realize the rotation and turnover function of Citrus in the conveying process. The control system scheme of the grading system is introduced in detail. Programmable Logic Controller (PLC) is used as the control core and NVIDIA Jetson tx2 (TX2) is used as the visual core. Finally, a small intelligent grading equipment integrating the functions of loading sequencing, transportation identification and grading unloading is built.
