Smart Parcel Sorting Control System Based on QR Code Recognition

A smart parcel sorting control system has been designed for logistics parcel sorting business. The system adopts STM32F103C8T6 microcontroller as the main control, based on infrared sensing and serial communication technology, combined with Qt software on the upper computer to achieve functions such as package infrared sensing, QR code recognition, and robotic arm control. The system includes two modes: manual control and automatic control. In manual control mode, users can directly control the robotic arm to sort packages through the buttons in the Qt software UI interface; In automatic control mode, when the package enters the system's sensing range, the system automatically takes photos and recognizes the package's QR code, and controls the robotic arm to sort the package based on destination information. The system operates stably and reliably, and can accurately and efficiently complete the automated sorting of logistics packages.
