Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of metallurgical plant pollutant monitoring and processing, and particularly relates to a metallurgical intelligent plant full-process dynamic optimization simulation and data interaction control method. BACKGROUND
[0002] At present, the steel industry has insufficient multi-source heterogeneous data fusion and sharing capability, and the pollutant emission prediction accuracy and over-standard traceability efficiency are insufficient. In the process of intelligent prediction and control of pollutants, the multi-source heterogeneous data of the whole process of industrial production has format barriers and semantic differences, and the data island problem is prominent, which restricts the construction of intelligent models driven by data, and it is necessary to establish a cross-platform data governance framework to realize full-process data penetration and efficient collaborative analysis. Traditional statistical models are difficult to handle the complex nonlinear and time-dependent relationship of pollutant emission data, and manual investigation of over-standard reasons is time-consuming and lacks quantitative means, so it is necessary to build a prediction model and an automatic traceback mechanism to improve the timeliness and accuracy of environmental protection supervision. The intelligent sensing and collaborative control capability of the dust removal system is insufficient, resulting in unstable smoke dust capture effect and difficulty in improving the control of unorganized emissions. Traditional dust removal relies on manual experience control, lacks real-time sensing of dust production scenes and quantitative methods for air volume, resulting in uneven dust collection, high energy consumption, and pipeline safety risks, and it is necessary to integrate machine vision, mechanism model and reinforcement learning technology to realize adaptive control of dust removal equipment and balance of energy saving goals.
[0003] Carbon emission accounting and data traceability are difficult. Enterprise carbon emission data is scattered in EMS, MES, ERP and other heterogeneous systems, and the data format and time granularity are not unified, resulting in difficulty in data integration, and the material flow data between processes have fuzzy boundaries, so it is necessary to build a dynamic correlation model of cross-system heterogeneous data to realize the spatio-temporal alignment of multi-source data (such as matching of EMS energy consumption data and MES process time sequence); domestic and foreign carbon accounting standards are updated frequently, enterprises need to meet multiple accounting rules at the same time, manual adjustment of accounting logic is inefficient, and carbon verification requires data traceability. Therefore, a metallurgical intelligent plant full-process dynamic optimization simulation and data interaction control method is needed to solve the problems of uneven dust collection, high energy consumption and low efficiency of manual adjustment of accounting logic of existing systems.

[0040] The technical solutions in the embodiments of the application will be further clearly, completely and specifically explained in combination with the drawings in the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the application.
[0041] As shown in Figure 1 , a metallurgical intelligent factory full-process dynamic optimization simulation and data interaction control method comprises the following steps:
[0042] 1. Build a pollutant monitoring module and a carbon footprint tracking module on the management platform, and establish the association between the pollutant monitoring module and the carbon footprint tracking module.
[0043] 2、Pollutant monitoring module monitors the factory's pollutant emissions through video images and sensor data collection, including the emissions inside the factory and the exhaust chimney. Video images are obtained through multiple angle monitoring cameras distributed inside the production factory, which are numbered on the management platform, such as LT001. When the image number of the monitoring camera is added, the time number is added to the back of the monitoring camera number according to the monitoring camera number, and a random number is added, such as LT0010711001.
[0044] The sensor uses MH-Z40A infrared gas sensor integrated smoke concentration sensor, which can monitor smoke concentration to determine particulate matter emissions, and can monitor gas types including but not limited to carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen oxides.
[0045] 3、The working factory area is intercepted by the installed fixed-point camera at regular intervals, and the picture is intercepted from the video during the non-production period as a comparison image, and the picture is intercepted from the video during the production period as a collection image. The comparison image and the collection image are uploaded to the pollutant monitoring module for comparison to determine the particulate matter emission situation.
[0046] The non-production time and production time are calculated according to the shift time on the production scheduling system connected by the management platform. During the non-production period, the image processing software set in the pollutant monitoring module intercepts three 30-second videos at intervals, and the image analysis software set in the pollutant monitoring module processes the middle frame of the video to intercept comparison images and store them in the memory. The image analysis software first compares and analyzes the three comparison images, and discards the unclear images and keeps one comparison image; the unclear images are deleted directly.
[0047] The collection during the production time is processed by the same operation process as the comparison image, and then the collection images obtained at different time nodes during the production time are respectively compared and analyzed with the comparison image of the last non-production time. Images exceeding one month are deleted to maintain the speed of memory and software processing. The diffusion of dust pollutants is determined, and when the similarity between the collection image and the comparison image is less than 80%, a pre-alarm is given to indicate that the dust pollutants in the production area exceed the standard, and the workers perform protective work, turn on the standby dust removal equipment and increase the power of the dust removal equipment.
[0048] The process of image matching and comparison analysis by the image analysis software is as follows:
[0049] 1) Feature detection: automatic feature detection is used, closed boundary, edge, contour, line intersection, corner and representative point such as barycenter or line end as special.
[0050] 2) Feature matching: Establishes correspondence between features detected in the acquired image and in the contrast image, using different feature descriptors and similarity measures to determine the accuracy of the registration.
[0051] 3) Evaluation of the image transformation model: To register the acquired image with the contrast image, the parameters of the mapping function need to be estimated, using the corresponding features obtained from step 2).
[0052] 4) Image transformation: The acquired image is transformed using the mapping to register, measuring the effectiveness by correlation.
[0053] Correlation is essentially a similarity measure to understand how similar the acquired image and the contrast image are, if the two images are identical, the correlation is equal to 1; if the two images are completely unrelated, the correlation value is equal to 0; if the correlation value is equal to -1, it means that the images are completely inversely related, one is the negative of the other. By using correlation as an evaluation criterion, monomodal registration obtains satisfactory results. By optimizing the similarity criterion between the two images, the transformation parameters are estimated, mainly the translation and rotation of the rigid body. Correlation is mainly limited to single-mode image registration, especially for comparing a series of images, from which small changes caused by changes in dust concentration are found.
[0054] The correlation formula is represented as:
[0055] where x i , y i are the intensities of the i-th pixel of the acquired image and the contrast image, respectively.
[0056] x m , y m are the average intensities of the acquired image and the contrast image.
[0057] 4. A flue gas monitoring sensor is installed in the flue, and the flue gas monitoring sensor collects the emission of pollution gases and particulate matters in the flue gas. The data collected by the flue gas monitoring sensor is uploaded to the pollutant monitoring module, and the emission of pollutants is predicted by the CNN-LSTM model, which provides data support for automatic calculation of carbon emissions and data traceability.
[0058] As shown in Figure 2 , the CNN-LSTM model includes:
[0059] 1) Input layer: First, the data is input into the CNN, including the data collected by the flue gas monitoring sensor and the comparison result data of the contrast image and the acquired image.
[0060] 2) Convolution layer: CNN extracts local features of data through convolution and pooling operations to generate feature maps.
[0061] 3) Flatten layer: flatten the feature map output by CNN into a one-dimensional vector.
[0062] 4) LSTM layer: input the flattened vector into LSTM, which processes sequence data through input gate, forget gate and output gate mechanism, capturing long-time dependencies.
[0063] 5) Output layer: output the prediction result of pollutant emission through fully connected layer and activation function.
[0064] The specific operation steps of CNN-LSTM model building: import the necessary libraries (image contrast of dust particle emission in factory area, collector collected smoke emission in chimney), load and prepare data, define data processing function, data set division and normalization processing, define and train the built CNN-LSTM model, draw training and validation loss curve, model prediction and inverse normalization processing, evaluate prediction performance, draw prediction results, form contrast analysis legend.
[0065] The convolution formula of CNN is represented as two-dimensional discrete convolution operation, which slides the convolution kernel on the input data and calculates the weighted sum of local area, the mathematical expression is:
[0066] Z(x,y) = i∑j∑I(x-1,y-1)·K(i,j);
[0067] Where I is the input data, K is the convolution kernel, and Z is the output feature map.
[0068] The calculation formula of forget gate of LSTM is: t = σ(W f ·[h t-1 ,x t ]+b f ); Where σ is the range function, W f is the weight matrix, b f is the bias term, and [h t-1 ,x t ] represents the concatenation of h t-l and x t .
[0069] The forget gate determines the discarded information, and the level of the forget gate takes the current input x t and the hidden state h t-1 of the last time as input, and outputs a vector f t with a value range between (0, 1), each element in the vector represents the degree of retention or discard of the corresponding data, 0 means completely discard, and 1 means completely retain.
[0070] The calculation formula of input gate is: Among them, ⊙ represents element-by-element multiplication, C t-1 The status at the previous moment.
[0071] The input gate is responsible for deciding what new information to add to the state. Part of this is done by using the range layer to decide which values need to be updated, which is called input gating. t , and the other part is to generate possible new information through the tanh layer.
[0072] The calculation formula of the output gate is:
[0073] The output gate controls the output of the state. The output gate is generated by the range layer. t Determines the degree of output; then, the state is transformed by the tanh layer and multiplied by the output gate to obtain the hidden state at the current moment.
[0074] 5. The pollutant monitoring module and the carbon footprint tracking module share data in the same database. The carbon footprint tracking module processes and analyzes data based on the collected information to complete automatic carbon emission accounting and data traceability.
[0075] The carbon footprint tracking module forms a dataset based on data collected from the database. The dataset is divided into four parts: X and Y. X is a set of factors most relevant to energy consumption, obtained through preliminary screening, and Y is the output of carbon energy consumption to be predicted. The change value dX of X is normalized, and the value of dX is distributed between -1 and 1. The same process is performed on Y. DTW clusters X and uses the cluster label as a feature. The original value of Y is an increasing quantity, which increases like a linear function, while dY is a jumping value. A sparse feature extracts key features through a sequence of time-equivalent pulse events, converting discrete data into continuous data.
[0076] After completing the preliminary preparations, make predictions and select GRU and large language models. Figure 3As shown, the specific operation consists of three steps. First, the time intervals within each hour are extracted. The red line in the upper left graph represents the time intervals where Y remains constant. Second, the hourly time intervals are averaged to produce the graph in the upper right. The averaged value is inversely proportional to the original discrete value. Third, the inverse of the average is directly taken to produce data that fits the original data, as shown in the figure below. The blue figure represents the original discrete data. The yellow figure represents the data after the second averaging operation, and the red figure represents the data after the inverse ratio is taken and aligned. Compared with the blue figure, the red and blue figures not only fit the trend but also convert the discrete data into continuous data. The processed red Y is used as the new output for prediction. The next step is feature selection, selecting the features most relevant to the three selected Y factors (for example, the three energy consumption features: Y1 particulate matter, Y2 carbon dioxide, and Y3 carbon monoxide). One method is correlation analysis, and the other is XGBoost. First, the correlation analysis is performed, using Y2, 1.0 MPa carbon dioxide. By calculating the correlation between each X and Y2, the 40% most relevant features are selected. Specifically, we first calculate a score function between each X and Y, as shown in the figure in the lower left corner. We then perform a statistical analysis, selecting the top 40% of factors, and then performing a final screening. In addition to calculating the correlation between X and Y, we also calculate the correlation between Y and Y. Y also has a strong autocorrelation with itself. Therefore, we also use past Y as input to predict future Y. Using XGBoost, we also screened for the same number of factors. The overlap between the two methods was approximately 50%. Finally, we used the previous year's data for prediction and found a relatively good fit for carbon traceability.
[0077] The present invention forms a pollutant precise prediction and low-carbon coordinated control technology, realizes the online prediction of environmental emission data, and traces the reasons for exceeding the standard in minutes; forms a dust removal intelligent control technology, realizes the improvement of particulate matter capture efficiency and on-demand intelligent regulation of the dust removal system; forms an accounting rule engine based on multi-source heterogeneous data, realizes the enterprise carbon emission accounting, online analysis management, dynamic tracking of carbon flow and precise data tracing, and effectively assists post personnel in formulating practical emission reduction plans.
[0078] Direct Economic Benefits: Reduced Carbon Compliance Costs: This will improve companies' real-time tracking and analysis of production emissions, combined with carbon pricing consulting to assist in the deployment of targeted carbon reduction pathways, effectively improving corporate carbon management and reducing their carbon trading compliance costs. Indirect Economic Benefits: The development of standardized, intelligent environmental management and control technologies will provide technical services to the industry, enhance corporate competitiveness, and potentially help companies achieve "Environmental Performance Grade A" and "Ultra-Low Emissions" ratings.
