Abstract
With the continuous improvement of industrial automation level, the intelligence and efficiency of mechanical equipment control system has become an important trend in the development of the industry. The design of mechanical equipment control system based on programmable logic controller (PLC) is designed to meet this demand. This study focuses on building a stable, reliable and easily maintained PLC control system, aiming to improve the operation efficiency and precision of mechanical equipment. Through the thorough analysis of the existing mechanical equipment control problems, such as the high complexity of the traditional relay control system, a new control scheme based on PLC is proposed. This scheme adopts the modular design concept, which divides the whole system into three main parts: signal acquisition, logical processing and execution output, and introduces the redundant design to ensure the stability of the system. In terms of hardware selection, PLC models suitable for specific application scenarios are selected considering performance index and cost factors; software programming follows IEC 61131-3 standard to accurately control the flow of mechanical equipment by using trapezoidal diagram language. The experimental results show that the designed PLC control system can effectively improve the equipment response speed, reduce the error rate, and realize the expected functional requirements.
