Abstract
With the advancement of Industry 4.0, automated production lines have become a critical factor in the transformation and upgrading of modern manufacturing. This paper addresses the limitations of traditional production line control systems and proposes a design scheme for an automated production line control system based on PLC (Programmable Logic Controller), aiming to enhance production efficiency, reduce failure rates, and optimize resource allocation. The study adopts a modular design approach, utilizing Siemens S7-300 PLC as the core controller and integrating fieldbus technology to construct a distributed control system architecture. By incorporating an intelligent sensor network and real-time data acquisition system, comprehensive monitoring and precise control of the production process are achieved. A key innovation lies in the development of an adaptive scheduling algorithm that can dynamically adjust production parameters according to actual operating conditions, significantly improving system flexibility and response speed. Additionally, a robust fault diagnosis expert system has been established to rapidly identify and resolve potential faults. Experimental results demonstrate that this system surpasses traditional solutions in terms of stability, reliability, and intelligence, with average production efficiency increasing by 25% and equipment utilization improving by 18%. This research provides a practical technical pathway for the smart manufacturing domain and is of significant importance for advancing China's manufacturing industry towards higher-end and smarter directions.
