[0007] The intelligent prediction module: comprehensively collects historical oxygen supply and demand data from the data center, which covers real-time monitoring information of oxygen flow, pressure, and temperature, as well as steelmaking production plan and equipment operation log related data, cleans and integrates the collected data, and pre-processes the integrated data to lay a solid foundation for subsequent data analysis, so as to better adapt to the input requirements of the prediction model according to the characteristics of the data;

[0008] In-depth analysis of historical data to identify key factors affecting oxygen demand, Among them, S ot represents the oxygen supply and demand state value at time t, g(X) represents a function with input data X as the independent variable, F i (t) is the function of the i-th influencing factor with respect to time t, D i (x) is the data characteristic value of the i-th influencing factor, x represents the relevant data point, w i is the weight coefficient of the i-th influencing factor, E(t) is the error correction term, which is a function of time t. Based on these factors, valuable features are extracted from the data as input variables of the prediction model.

[0029] After the data is uploaded, the uploaded data is verified, such as checking the integrity and accuracy of the data. For data that fails the verification, it is retransmitted or marked to ensure the reliability of the data. The uploaded data is compared and analyzed with historical data to verify the rationality and consistency of the data. For abnormal data or data that does not meet expectations, further analysis and processing are performed to ensure the accuracy and reliability of the data.

The uploaded data is used for training and verification of intelligent prediction models to improve the accuracy of predictions. The data is used to monitor and optimize the production process to improve production efficiency and product quality. The data is used for fault warning and diagnosis to improve the reliability and safety of equipment.

[0030] Comprehensively collect historical oxygen supply and demand data from the data center. These data cover real-time monitoring information of oxygen flow, pressure, and temperature, as well as steelmaking production plans and equipment operation log-related data. Clean and integrate the collected data, remove duplicate, erroneous or invalid data, and pre-process the integrated data to lay a solid foundation for subsequent data analysis, so as to better meet the input requirements of the prediction model according to the characteristics of the data;

[0031] In-depth analysis of historical data to identify key factors affecting oxygen demand, Among them, S ot represents the oxygen supply and demand state value at time t, g(X) represents a function with input data X as the independent variable, F i (t) is the function of the i-th influencing factor with respect to time t, D i (x) is the data characteristic value of the i-th influencing factor, x represents the relevant data point, w i is the weight coefficient of the i-th influencing factor, E(t) is the error correction term, which is a function of time t. Based on these factors, valuable features are extracted from the data as input variables of the prediction model.

The model's prediction ability is improved by adjusting the model parameters and algorithm structure;

[0032] Use cross-validation, hold-out method or online learning method to verify the trained model and evaluate its prediction performance. According to the verification results, make necessary adjustments and optimizations to the model to improve its accuracy and generalization ability. Apply the optimized model to new data to predict oxygen demand in the future. σ(t)·Z, where O future (t) represents the predicted oxygen demand at future time t, The M in it represents a mapping function, which transforms the optimized parameter vector New data X new and the future time point t as input, f(t) is the time adjustment function, is the kth parameter obtained after model optimization, B k (X new ) is based on the new data X new The kth characteristic function, g k (t) is a time-dependent uncertainty measurement function, Z is a random variable that obeys a standard normal distribution, and the prediction result should include the predicted value and its confidence interval to reflect the uncertainty of the prediction;

[0033] Conduct in-depth analysis of the forecast results to understand the supply and demand changes and trends behind them, apply the forecast results to actual production scheduling and decision-making, guide the operation adjustment of air separation equipment and oxygen storage systems, and achieve a dynamic balance between oxygen supply and demand. As time goes by and new data is generated, the forecast model is regularly updated and maintained, new features and data sources are introduced, and the model structure and parameters are optimized to adapt to the ever-changing production environment and needs.

[0034] The dynamic scheduling module first receives the forecast data from the intelligent prediction module. These data include the expected oxygen demand in the future. The received forecast data are analyzed to clarify the oxygen demand and demand trend in different time periods. According to the analyzed forecast data, the dynamic scheduling module automatically adjusts the operating parameters of the oxygen production equipment to ensure that the oxygen production can match the predicted oxygen demand. The adjustment process may involve the coordinated control of multiple oxygen production equipment to achieve the optimal oxygen production efficiency. The current reserve information of the oxygen storage tank is obtained in real time through sensors or other monitoring means. The monitoring data is compared with the preset safety inventory standard to evaluate the adequacy of oxygen reserves.

[0035] According to the real-time monitored oxygen reserve data, the dynamic scheduling module optimizes the oxygen release strategy to avoid waste when there is excess oxygen. At the same time, it formulates and implements an oxygen replenishment plan to ensure that the reserve can be replenished in time when the oxygen demand peaks to avoid shortages. The dynamic scheduling module uniformly manages and schedules all equipment in the air substation area, and optimizes the overall resource allocation and improves resource utilization efficiency by coordinating the operation of various equipment. According to real-time demand and equipment status, the dynamic scheduling module automatically adjusts the operation mode and sequence of each device to ensure that they can work together to meet oxygen demand. Collaborative operation may involve load balancing and fault switching strategies between equipment to improve system reliability and stability;

[0036] Through the comprehensive implementation of the above steps, the dynamic scheduling module can significantly improve the reliability and efficiency of oxygen supply. Real-time monitoring and dynamic adjustment can ensure the timeliness and accuracy of oxygen supply to meet the actual needs of users.

[0037] The human-computer interaction module should first design an intuitive and easy-to-use user interface to ensure that operators can easily understand and operate. The interface should include a display area for real-time oxygen supply and demand data, forecast results, and dispatch instruction information, so that operators can check the system status at any time and obtain real-time oxygen supply and demand data from the system, including the current oxygen flow, pressure, temperature, and storage tank reserves. These data should be dynamically updated on the user interface so that operators can understand the system's operating status in real time.

[0038] Receive the output results of the intelligent prediction module, including the oxygen demand forecast for a period of time in the future, receive the dispatch instructions of the dynamic dispatch module, and clearly display these prediction results and dispatch instructions on the user interface so that operators can understand the future status and dispatch plan of the system. Provide an operation interface to allow operators to modify and optimize the system prediction and dispatch results according to actual conditions. Operators can adjust the operation of the system by entering new parameters or selecting different strategies;

[0039] After completing the correction and optimization, the operator confirms the modified content through the interface. The human-computer interaction module passes the confirmed modified content to the intelligent prediction module and the dynamic scheduling module so that the system can adjust according to the new instructions. The operator can provide feedback through the user interface. The human-computer interaction module collects this feedback and passes it to other modules of the system for continuous optimization and improvement.

[0040] Embodiment 2

[0041] A series of high-precision sensors have been carefully installed at key locations of air separation equipment, oxygen storage tanks and steelmaking equipment. These sensors can monitor key parameters such as oxygen flow, pressure, temperature, etc. in real time to ensure the accuracy and real-time nature of the data. Professional data acquisition equipment is configured to receive signals transmitted by sensors and convert them into data formats that can be used for analysis. At the same time, reasonable communication parameters are set to ensure stable communication between the data acquisition equipment and the data center. The data acquisition equipment automatically collects and stores data according to the set cycle and frequency. Before the data is uploaded to the data center, format conversion and encryption verification will be performed to ensure data compatibility and security. After uploading, the data will undergo further verification and validation and will eventually be stored in the data warehouse, providing strong support for subsequent intelligent prediction, production monitoring optimization, and fault warning diagnosis.

[0042] Using the historical oxygen supply and demand data stored in the data center, we conducted in-depth data cleaning, integration and preprocessing. By removing duplicate, erroneous or invalid data, we improved the quality and availability of the data. Based on the preprocessed data, we built an oxygen demand forecasting model. Among them, O pred (t) represents the predicted oxygen demand at time t, h represents a mapping function, θ j is the parameter vector related to the jth algorithm, A j (X, t) is the jth algorithm basis function based on data X and time t, ∈(t) is the error term. The model uses a machine learning algorithm to deeply explore the potential laws and trends in the data.

[0043] The forecasting model not only takes into account historical oxygen supply and demand data, but also combines real-time production data and equipment operation record information to achieve accurate forecasts of oxygen demand in the future. Among them, O future (t) represents the predicted oxygen demand at future time t, The M in it represents a mapping function, which transforms the optimized parameter vector New data X new and the future time point t as input, f(t) is the time adjustment function, is the kth parameter obtained after model optimization, B k (X new ) is based on the new data X new The kth characteristic function, g k (t) is a time-related uncertainty measurement function, Z is a random variable that obeys the standard normal distribution, and the prediction result includes the predicted value and its confidence interval, providing a reliable basis for subsequent dynamic scheduling.

[0044] According to the output results of the intelligent prediction module, the dynamic scheduling module can automatically adjust the operating parameters of the oxygen production equipment to match the predicted oxygen demand. This function ensures the timeliness and accuracy of the oxygen supply and effectively avoids the problem of insufficient or excessive oxygen supply. At the same time, the dynamic scheduling module also monitors the reserves of oxygen storage tanks in real time and compares them with the safety inventory standards. According to the comparison results, the module can optimize the oxygen release and replenishment strategy to ensure that the reserves of oxygen storage tanks always remain within a reasonable range. In addition, the dynamic scheduling module also integrates the overall resources of the air separation station area, realizes the coordinated operation of equipment, and improves the reliability and efficiency of oxygen supply through unified management and scheduling of all equipment.

[0045] An intuitive and easy-to-use user interface is designed to display real-time oxygen supply and demand data, forecast results and future scheduling instructions. The interface is dynamically updated, allowing users to clearly understand the current status and future needs of the system. An operation interface is provided to support manual intervention. Operators can correct and optimize system forecasts and scheduling results according to actual conditions. After completing the correction, the modification content is confirmed through the interface. The human-computer interaction module will pass the update to related modules to ensure continuous optimization and improvement of the system.
