Description

[0002] At present, the production of cementitious filling shows a trend of increasingly higher filling mortar concentration. On the one hand, it brings the advantages of reducing the drainage pressure of the empty area, improving the filling connection effect, improving the filling body strength and the safety of the empty area, but it also brings the disadvantage of the difficulty of preparing the filling mortar, which is mainly manifested in the poor workability of the mortar, the high consistency of the mortar, and the easy adhesion to the mixing equipment. Long-term adhesion will cause agglomeration. The blocks formed by the condensation of the mortar are at risk of peeling off during the mixing process. After falling into the mortar, they will flow into the pipeline together with the mortar, which is one of the main reasons for the blockage of the filling pipeline.

[0003] In the prior art, when the water vapor vibration method is used to prevent the mortar from adhering to the wall of the mixing barrel, the high-pressure water vapor impacting the mortar will produce a large amount of foam, and the foam will carry solid particles and overflow from the installation gaps, etc., which will increase the cleaning burden and may also cause damage to the device.

[0049] Application of neural network in intelligent anti-sticking system for high-concentration tailings mortar

[0050] In order to realize the intelligent prediction and dynamic optimization of the adhesion risk of high-concentration tailings mortar, the present invention designs an intelligent control system based on neural network. The system realizes the quantitative prediction of adhesion risk by real-time analysis of multi-dimensional data, and provides optimized water-gas shock vibration parameters for dynamic adjustment of the device operation status. The following is a detailed description of data acquisition, network functions, operation mechanism and innovative advantages.

[0051] 1. Data collection and input mechanism

[0052] The effective operation of the neural network depends on accurate data input. This system has designed a complete multi-parameter real-time acquisition system, covering the physical properties of the mortar, operating conditions and environmental factors:

[0053] (1) Mortar physical performance parameters: Concentration C, viscosity V and lime-sand ratio R are key variables affecting adhesion risk. These data can be continuously monitored by online ultrasonic concentration meter and rotational viscometer and used as the basic input of the neural network.

[0054] (2) Operating condition parameters: The stirring temperature T, the rotation speed Sr and the amount of mortar in the bucket Ms are real-time operating variables that have a direct impact on the fluidity and adhesion risk of the mortar. These data are collected and updated in real time by the corresponding temperature, rotation speed and weight sensors.

[0055] (3) Environmental factor parameters: Ambient humidity H and air temperature Te are important external influencing factors. Through high-precision environmental sensors, these data are quantified as model inputs to enhance the network's ability to adapt to complex environmental changes.

[0056] After preprocessing, these data are used as input vector X and standardized uniformly: X = [C, V, R, T, Sr, Ms, H, Te]

[0057] The normalization formula is:

[0058] Where Xmin and Xmax are the minimum and maximum values ​​of each parameter respectively.

[0059] 2. Functions and architecture of neural networks

[0060] The main function of the neural network is to predict the adhesion risk Ra and output the optimal water-vapor shock parameters P = [Pw, Pq, F].

[0061] Ra∈[0,1]: represents the adhesion risk score, the higher the value, the greater the adhesion risk;

[0062] Pw: water vapor injection pressure, in kPa;

[0063] Pq: water vapor injection flow rate, unit is L / min;

[0064] F: vibration frequency, in Hz.

[0065] The neural network architecture includes an input layer, a hidden layer, and an output layer. It adopts standardized deep learning design logic and has strong adaptability and scalability.

[0066] Input layer: receives normalized multi-dimensional input data X

[0067] Hidden layer: contains several nonlinear activation function nodes, which are used to extract complex features. The output of each layer is calculated by ReLU activation function: i =ReLU(W i h i-1 +b i )

[0068] where h i-1 is the output of the previous layer, W i and b i are the weight matrix and bias vector respectively.

[0069] Output layer: consists of two parts:

[0070] 1) Adhesion risk score: R a =s(W risk h L +brisk ), where s(x) is the Sigmoid activation function.

[0071] 2) Optimization parameter output: P = P w ,P q ,F=ReLU(W params h L +b params )

[0072] 3. Data processing and dynamic adjustment mechanism

[0073] In order to ensure the real-time performance and accuracy of the model, a dynamic data processing and adjustment mechanism is designed. First, after the real-time data is input, the network calculates the adhesion risk score under the current conditions through the feature extraction module and compares it with the preset risk threshold. If the score exceeds the threshold, the system immediately triggers the adjustment mechanism to dynamically adjust the water vapor injection pressure, flow rate and vibration frequency. In addition, the system will continue to monitor the effect of the adjustment and fine-tune the model parameters to gradually improve the accuracy of the prediction and the effectiveness of the control. The specific logic is as follows:

[0074] 1) Adhesion risk detection: Calculate Ra in real time. If Ra>Rthreshold (risk threshold), the adjustment mechanism is triggered.

[0075] 2) Parameter optimization: According to P = [Pw, Pq, F], the operating status of the water vapor injection and vibration system is dynamically adjusted.

[0076] 3) Feedback update: The system monitors the effect of the adjustment, re-inputs the new data into the network, and uses the optimization results as input for the next cycle.

[0077] Through this mechanism, the network can complete risk prediction and parameter adjustment within milliseconds, ensuring the stability and efficiency of the mixing process.

[0078] 4. Model training and optimization

[0079] In order to improve the applicability and generalization ability of the model, the training data of the neural network comes from a wide range of sources, including historical operation records, simulation experiment results and real-time acquisition data. Through the supervised learning method, the loss function of the model is defined as the weighted sum of the adhesion risk prediction error and the operation parameter optimization error. During the optimization process, the adaptive gradient descent algorithm is used to dynamically adjust the weights to quickly converge to the global optimal solution.

[0080] 5. Network type and flexibility

[0081] The present invention does not limit the specific type of neural network to ensure the versatility and adaptability of the model. The network structure can be adjusted according to actual needs, including but not limited to:

[0082] 1) Multilayer Perceptron (MLP): Suitable for processing small-scale, fixed-dimensional data.

[0083] 2) Convolutional Neural Network (CNN): If you need to process input data with strong temporal and spatial correlation (such as time series or images).

[0084] 3) Recurrent Neural Network (RNN): Suitable for continuous time series prediction.

[0085] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
