Abstract In a certain cement company, various industrial information control systems operate independently, resulting in fragmented production management data such as energy consumption indicators, cost analysis, and equipment maintenance. This necessitates multi-system, cross-disciplinary comprehensive analysis, leading to issues such as high workload, time-consuming processes, and low efficiency. By introducing an intelligent energy management system, we constructed an integrated control platform that combines energy management with production management. Using intelligent metering instruments and multiple methods to collect parameters from the cement production process, quality inspection, and energy consumption, the control center utilizes interface machines to integrate real-time energy measurement data collected from various operating control systems for statistical analysis. This achieves an intelligent management process for various types of energy, from procurement and storage, processing and conversion, to transportation and distribution, and ultimately usage, making it "visible, knowable, and controllable". After implementing the intelligent energy management system, the company can save 16,677 tons of standard coal annually, with a comprehensive energy saving rate of 7.2%; it can also increase net profits by 4.52 million yuan, achieving an input-output ratio of 1:2, with significant economic benefits.
