Design of Multifunctional Piecework Display System Based on QT

In modern industry, visual management of production lines and accurate counting of products are important. This paper designs a set of multi-functional production line piecework display system based on QT, aiming to solve the problems of low efficiency and prone to errors in traditional piecework statistics methods. The system is divided into two parts: the lower computer and the upper computer. The lower computer takes the STC89C52 single-chip microcomputer as the control center, uses the infrared sensor for accurate piecework counting, and displays the piecework quantity, ambient temperature and other related data in real time through the OLED display screen. The upper computer can perform management of multiple production lines and receive piecework data in real time for analysis and processing to ensure the stable operation and product quality of the production line, which can effectively improve production efficiency and management level.
