Abstract
With the advancement of Industry 4.0, automated production lines are increasingly widely used in the manufacturing industry, but their energy efficiency problems are also gradually prominent. The purpose of this study is to explore the energy efficiency optimization strategy of automated production line in order to improve production efficiency and reduce energy consumption. The research background shows that as a global manufacturing power, China's industrial electricity consumption accounts for the proportion of total electricity consumption in the country is increasing year by year, so improving the energy efficiency of automated production lines has important economic and environmental significance. The purpose of this study is to systematically analyze the energy efficiency bottleneck of the existing automated production line and propose a feasible optimization scheme. To this end, this study adopted a multi-layered methodology: First, through field research and data collection, to identify the key factors affecting energy efficiency; Secondly, the simulation model is used to simulate and analyze different optimization strategies. Finally, the optimization effect is verified by a practical case. It is found that the energy efficiency optimization of automated production line mainly focuses on three aspects: equipment renewal, process improvement and intelligent control system. In terms of equipment renewal, the use of high-efficiency motors and frequency converters can significantly reduce energy consumption; In terms of process improvement, energy efficiency can be increased by up to 15% by optimizing production processes and reducing idling time; In terms of intelligent control systems, the introduction of Internet of Things technology and big data analysis has achieved real-time monitoring and dynamic adjustment, further improving energy efficiency. The main contribution of this study is to propose a comprehensive energy efficiency optimization fr amework, which is not only applicable to a single production line, but also can be extended to the whole plant and even the industry level. In addition, the intelligent control system proposed in the research innovatively combines machine learning and artificial intelligence technology, providing a new idea for the development of automated production lines in the future.
