Plc-based production data acquisition and management system for integrated production lines

Abstract

This new patent relates to a production line integrated programmable logic controller (PLC) production data acquisition and management system. The main innovation lies in using a single programmable logic controller (PLC) as the core to centrally acquire and integrate the operating signals of multiple production line equipment, and converting the processing actions of each equipment into digital signals through sensors, which are then input into the internal program of the programmable logic controller (PLC) for logical judgment and calculation. This system can integrate and display production data that was originally scattered across various machines and required manual aggregation, including processing cycles, processing time, and output information, in real time. It treats the entire production line as a single management unit for data acquisition and analysis. Compared to traditional methods of building systems on a machine-by-machine basis or relying on equipment communication protocols, this invention has better applicability to low-automation equipment and system scalability. This new system effectively reduces system setup costs and equipment integration complexity through a centralized architecture design, shortens data transmission and processing paths, improves the timeliness and consistency of production data, and reduces manual workload. Overall, it can improve production line management efficiency and space utilization flexibility.
