Description

Technical Field

[0001] The present invention relates to the technical field of stirring control, and in particular to an intelligent speed-regulating stirring control method, system and computer equipment. Background Art

[0002] In thermal power plants, the tumbling or stirring of combustion materials is critical, as it directly affects combustion efficiency, power generation efficiency, and safety. During the combustion process, fuel (such as pulverized coal) needs to be in full contact with oxygen in the air to completely burn. Stirring can enhance the dispersion and uniformity of fuel particles, thereby increasing the contact area between fuel and oxygen and promoting the combustion reaction. Therefore, in thermal power plants, the stirring of combustion materials is a key step to ensure full combustion of fuel and optimize power generation efficiency.

[0003] Traditional mixing control often relies on manual adjustment of the mixing speed, which presents problems such as high labor costs, low efficiency, and imprecise control. This is especially true under complex working conditions, where dynamic adjustment is required based on a variety of factors, such as the properties of the fuel used in the mixing process, the shape of the mixing vessel, temperature, and viscosity. Manual control is unable to dynamically adjust the speed based on real-time mixing process information, making it impossible to achieve accurate and efficient mixing control. Traditional mixing control methods lack real-time monitoring and feedback mechanisms, making it impossible to understand the mixing process in real time, resulting in an inability to dynamically adjust the speed based on actual conditions. The root cause is the lack of intelligent control algorithms and information collection, processing, and feedback mechanisms.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0078] like Figure 1-Figure 3 As shown, the present application provides an intelligent speed-regulating stirring control method, comprising:

[0079] S1. Obtaining the stirring process requirements of the combustion furnace and determining the target control value of the stirring control according to the stirring process requirements;

[0080] S2.

[0084] S6. Establishing a mathematical model of the combustion furnace stirring process based on the key characteristics for prediction and control;

[0085] S7. Adjust the stirring speed of the combustion furnace according to the real-time monitoring data. According to the real-time parameter changes during the stirring process, dynamically adjust the stirring speed to adapt to different working conditions.

[0086] As described in steps S1-S7 above, the stirring or agitation of the combustion materials is crucial in thermal power plants, directly impacting combustion efficiency, power generation efficiency, and safety. During the combustion process, the fuel needs to be in full contact with the oxygen in the air for complete combustion to occur. Stirring can enhance the dispersion and uniformity of the fuel particles, thereby increasing the contact surface between the fuel and oxygen and promoting the combustion reaction. Therefore, in thermal power plants, the stirring of the combustion materials is a key step in ensuring full fuel combustion and optimizing power generation efficiency. Traditional stirring control often relies on manual adjustment of the stirring speed, which has problems such as high labor costs, low efficiency, and imprecise control. Especially under complex operating conditions, dynamic adjustment is required based on multiple factors such as the properties of the stirring thermal power generation combustion materials, the shape of the stirring vessel, temperature, and viscosity. Manual control is difficult to dynamically adjust the speed based on real-time stirring process information, making it impossible to achieve accurate and efficient stirring control. Traditional stirring control methods lack real-time monitoring and feedback mechanisms, making it impossible to understand the stirring process in real time, resulting in an inability to dynamically adjust the speed based on actual conditions. The root cause is the lack of intelligent control algorithms and information collection, processing, and feedback mechanisms. The present invention obtains the stirring process requirements of the combustion furnace, determines the target control value of the stirring control according to the stirring process requirements, calculates the mixing uniformity, production efficiency and energy consumption according to the targets, and obtains the architecture of the entire intelligent stirring control system. By dynamically adjusting the stirring speed according to real-time stirring process information (such as mixing uniformity, temperature, viscosity, etc.), the intelligent stirring control system can optimize the stirring effect in real time to ensure that the uniformity of the mixture meets the expected standard. This dynamic adjustment not only improves the stirring accuracy, but also avoids over-stirring or under-stirring, reduces the waste of combustion materials and process deviations in thermal power generation, and through real-time monitoring and feedback mechanisms, the system can automatically adjust the stirring conditions such as speed, time, etc. according to real-time data, thereby reducing the intervention of manual operation and shortening the production cycle. The intelligent control system can adjust the process parameters in real time according to the actual mixing state, thereby increasing production speed without reducing quality and increasing production The efficiency of the line is improved by accurately calculating and dynamically adjusting the speed, avoiding excessive or low energy consumption and improving the energy efficiency of the mixing process. By integrating sensors, data acquisition modules and feedback mechanisms, comprehensive monitoring of the mixing process is achieved. This real-time monitoring can not only provide process data, but also timely alarm and adjustment when abnormalities occur, avoiding quality problems caused by human negligence or equipment failure in the production process. Through the feedback mechanism, the system can continuously optimize various parameters in the mixing process, thereby maintaining the long-term stability of the process. By installing various sensors on the mixing equipment and collecting key parameters in the mixing process in real time, setting the data collection frequency, ensuring that the dynamic changes in the mixing process are captured, filtering the collected sensor data, removing noise interference, and correcting the sensor data to ensure data accuracy, the system can dynamically adjust the mixing speed according to real-time data through the feedback mechanism.Ensure that the mixing process is always carried out under the best working conditions, thereby improving the mixing efficiency and quality. By filtering the collected data, these noises can be removed to ensure the smoothness and accuracy of the data, which is crucial for dynamically adjusting the mixing parameters, because only with the support of accurate data can the intelligent control algorithm make effective adjustments. By collecting data in real time and applying intelligent control algorithms, the mixing system can achieve a high degree of intelligence. Intelligent algorithms (such as machine learning, deep learning, etc.) can predict the changing trends in the mixing process based on historical data and real-time data, and automatically adjust the key parameters of the mixing. This intelligent control not only improves the accuracy of the mixing process, but also can effectively respond to different production batches, different thermal power generation combustion characteristics, etc. Changes, automatic optimization of the stirring process, through real-time dynamic adjustment of the stirring speed, the intelligent control system can select the optimal speed according to the actual state of the stirring thermal power combustion material, which not only avoids the waste caused by excessive stirring, but also improves the stirring efficiency and shortens the production cycle. By optimizing the speed and stirring parameters, the system can also reduce energy consumption and reduce unnecessary energy waste. The key features of the stirring process of the combustion furnace are extracted through data analysis methods, and a mathematical model of the stirring process is established based on the key features for prediction and control. The stirring speed of the combustion furnace is adjusted according to the real-time monitoring data. According to the real-time parameter changes in the stirring process, the stirring speed is dynamically adjusted to adapt to different working conditions. Through real-time monitoring data (such as temperature, pressure, viscosity, state of the stirring material), the stirring speed is adjusted according to the real-time monitoring data. By extracting key features from the stirring process (such as state, etc.), the stirring speed can be dynamically adjusted under different working conditions, making the stirring process more precise and ensuring the best stirring quality. Real-time adjustment of the stirring speed can reduce unnecessary energy waste or over-stirring, avoiding low production efficiency caused by improper speed setting in traditional methods, thereby improving overall production efficiency. The algorithm automatically analyzes data and dynamically adjusts the stirring speed according to actual conditions, reducing interference from human factors and the possibility of operational errors. By collecting various parameters in the stirring process in real time (such as temperature, viscosity, pressure, rheological properties of the stirred material, etc.), the dynamic changes of the stirring process can be fully understood. These data provide a sufficient basis for dynamically adjusting the stirring speed, avoiding the low production efficiency caused by the lack of real-time stirring in traditional methods. In order to solve the problem of inability to accurately adjust due to timely feedback, real-time monitoring data can be fed back to the control system to form a closed-loop control. By comparing the data deviation between the prediction model and the actual mixing process, the system can quickly adjust the rotation speed to ensure that the process control is within the expected range, thereby improving the stability and reliability of mixing. In the actual production process, factors such as raw material quality and external environment often change. Traditional control methods are often unable to adapt to these changes quickly. Intelligent control systems based on data analysis can quickly respond to these changes, automatically adjust the mixing speed, and ensure the smooth operation of the production process. By real-time monitoring of the system status and key features of the mixing process, the intelligent control system can identify potential faults or anomalies, issue early warnings, and avoid system failures.This improves the reliability and maintainability of the equipment. Based on the system characteristics, appropriate control algorithms, such as PID control, fuzzy control, adaptive control, and neural network control, are selected. The parameters of the selected control algorithm are tuned to achieve optimal control performance. A closed-loop control system is established to adjust the mixing speed of the combustion furnace based on real-time monitoring data. The mixing speed is dynamically adjusted based on real-time parameter changes during the mixing process to adapt to different operating conditions. A user-friendly interface is designed to facilitate operator monitoring and control of the mixing process. Key parameters during the mixing process are displayed in graphical form, allowing operators to understand the mixing status in real time. All hardware and software components are integrated to ensure coordinated operation. System testing verifies whether it can achieve the desired control objectives. Control algorithms and system parameters are continuously optimized based on actual operating data. Long-term stable operation of the system is ensured through regular maintenance of sensors and equipment. Safety protection mechanisms are designed to prevent abnormal conditions such as overload and overheating. A fault diagnosis system is established to promptly detect and address system faults. The above approach effectively addresses the problems existing in traditional mixing control and achieves more accurate, efficient, and reliable mixing control.

[0087] In one embodiment, the step S3 of installing various sensors on the stirring device includes:

[0088] S31. Set up a speed sensor to monitor the speed of the stirrer and ensure that the stirring speed meets the set requirements. Install it on the stirring shaft or motor;

[0089] S32. Setting a temperature sensor to monitor the temperature of the stirred thermal power generation combustion material to prevent overheating or overcooling from affecting the stirring effect. The temperature sensor is immersed in the thermal power generation combustion material or installed on the wall of the stirring container;

[0090] S33, setting a viscosity sensor to measure the viscosity of the thermal power generation combustion product and help adjust the stirring speed to adapt to the thermal power generation combustion product of different viscosities, and the sensor is installed inside the stirring container and directly contacts the thermal power generation combustion product;

[0091] S34. A liquid level sensor is provided to monitor the liquid level in the mixing container to prevent overflow or lack of material. The sensor is installed on the side wall or bottom of the mixing container;

[0092] S35. Set up a torque sensor to measure the torque of the stirring shaft and reflect the load during the stirring process. Install it between the stirring shaft and the motor.

[0093] S36. Install a pressure sensor to monitor the pressure in the mixing vessel to ensure safe operation. Install the sensor on the side wall or other pressure-sensitive point of the mixing vessel.

[0094] S37. A flow sensor is provided to monitor the flow of feed or discharge, control the input and output of combustion materials for thermal power generation, and is installed on the feed pipe or discharge pipe;

[0095] S38. A density sensor is provided to measure the density of the combustion products of the thermal power generation and assist in controlling the stirring process. The sensor is installed inside the stirring vessel or on related pipes.

[0096] S39. Setting a pH sensor to monitor the pH value of the thermal power generation combustion product is particularly important for the stirring process that requires pH control. Directly immerse the sensor in the thermal power generation combustion product.

[0097] S310. Set up a component analysis sensor to monitor the composition ratio of thermal power generation combustion products in real time to ensure uniform mixing. Install it inside the stirring container or at relevant sampling points.

[0098] As described in the above steps S31-S310, the rotation speed of the agitator is monitored by a rotation speed sensor to ensure that the stirring speed meets the set requirements, the temperature of the stirred thermal power generation combustion material is monitored by a temperature sensor to prevent overheating and overcooling from affecting the stirring effect, the viscosity of the thermal power generation combustion material is measured by a viscosity sensor to help adjust the stirring speed to adapt to thermal power generation combustion materials with different viscosities, the liquid level in the stirring container is monitored by a liquid level sensor to prevent overflow and lack of material, the torque of the stirring shaft is measured by a torque sensor to reflect the load conditions during the stirring process, the pressure in the stirring container is monitored by a pressure sensor to ensure safe operation, the flow rate of feed and discharge is monitored by a flow sensor to control the input and output of the thermal power generation combustion material, and the sealing The density sensor measures the density of the thermal power generation combustion material and assists in controlling the stirring process. The pH sensor monitors the pH value of the thermal power generation combustion material, which is particularly important for the stirring process that needs to control the acidity and alkalinity. The component analysis sensor monitors the component ratio of the thermal power generation combustion material in real time to ensure uniform mixing. Through the monitoring of the speed sensor, viscosity sensor and other key parameters, the system can adjust the speed, temperature and other variables of the agitator in real time to ensure that they are always within the optimal range. By monitoring various parameters (such as temperature, viscosity, pressure, density, etc.) in real time, the system can intelligently adjust the stirring conditions according to the real-time status of the thermal power generation combustion material to ensure that each stirring achieves the best effect. Dynamic adjustment can avoid over-stirring or under-stirring. Stirring, reducing invalid working time during the stirring process, thereby improving efficiency. Temperature sensors, pressure sensors and liquid level sensors can detect abnormal conditions that may occur during the stirring process (such as overheating, overcooling, overflow or excessive pressure, etc.) in real time, and take timely measures, such as automatic shutdown or adjustment of operating parameters, to prevent equipment damage or loss of thermal power generation combustion materials. Through the real-time data of viscosity, pH, density and component analysis sensors, it is possible to ensure the uniform mixing of thermal power generation combustion materials, avoid uneven composition, and ensure the quality of the final product. For the stirring process that requires strict control of pH or the proportion of thermal power generation combustion materials, pH sensors and component analysis sensors provide accurate monitoring data and support dynamic adjustment to ensure each All batches meet the quality standards. Through the application of these sensors, the system can automatically collect and process data, conduct real-time feedback and adjustments, greatly improving the intelligent level of operation. Automatic adjustment not only reduces errors caused by human intervention, but also responds more quickly to changing production needs and adapts to the characteristics of different thermal power generation combustion materials. Precise speed control and real-time feedback mechanism help avoid excessive stirring, thereby saving energy. Reasonable temperature, pressure and flow control also help reduce waste of thermal power generation combustion materials, reduce energy consumption and improve resource utilization efficiency. Real-time monitoring of sensors such as pressure, temperature and liquid level can ensure that the mixing container operates within a safe range, prevent dangerous situations such as overflow and overpressure, and ensure the safety of operators and equipment.

[0099] In one embodiment, in order to capture the dynamic changes during the stirring process, it is necessary to set an appropriate data acquisition frequency. The setting of the data acquisition frequency should consider the following factors:

[0100] Agitation speed: Higher agitation speeds require more frequent data acquisition to capture rapid changes.

[0101] Characteristics of thermal power generation combustibles: Different thermal power generation combustibles have different reaction speeds. Thermal power generation combustibles with high viscosity or slow reaction can adopt a lower collection frequency.

[0102] Control accuracy: Higher control accuracy requires more frequent data collection.

[0103] System response time: The response time of the control system will also affect the setting of data collection frequency.

[0104] Typically, the data collection frequency can range from several to dozens of times per second, depending on actual needs. By rationally arranging these sensors and setting a suitable data collection frequency, comprehensive monitoring and control of the mixing process can be achieved, thereby improving the mixing effect and production efficiency.

[0105] The step S4 of filtering the collected sensor data to remove noise interference includes:

[0106] S41. Filter the data collected by the sensor to remove noise interference in the sensor data and retain useful signals. The data curve is smoothed by taking the average value of a certain number of consecutive data points. The calculation formula is as follows:

[0107]

[0108] Among them, y(t) is the filtered data, x(ti) is the data at time (ti), and n is the size of the translation window;

[0109] S42. Perform data correction on the collected data to eliminate the inherent error of the sensor and improve the accuracy of the data. In the absence of an input signal, adjust the sensor output to zero. Measure the output value of the sensor in the zero input state and use it as an offset to subtract from subsequent measurements. The calculation formula is as follows:

[0110] x1=x0-x;

[0111] Among them, x1 is the correction data, x0 is the measurement data, and x' is the zero point offset;

[0112] S43. First, eliminate the zero offset of the sensor and adjust the sensitivity of the sensor so that its output matches the actual value. According to the characteristics of the sensor, perform linear or nonlinear correction and filter the corrected data to remove noise interference.

[0113] As described in steps S41-S43 above, sensor output is affected by temperature. Temperature compensation is used to eliminate temperature drift. The temperature sensor collects temperature data. A relationship model between temperature and sensor output is established. The sensor output is corrected based on the temperature data. Statistical methods, such as z-score and IQR, are used to identify and remove outliers. For removed outliers, interpolation is performed using the previous and next data. Data range is checked to ensure that the data is within a reasonable range. Data trends are analyzed to determine if the data trends meet expectations. Through the above steps, the sensor data can be effectively filtered and corrected to improve the accuracy and reliability of the data, providing a solid foundation for subsequent control and analysis. The sensor data is filtered to remove noise interference in the sensor data and retain useful signals. By taking the average of a certain number of consecutive data points, the data curve is smoothed, and the collected data is corrected to eliminate the inherent error of the sensor and improve the accuracy of the data. The sensor output is adjusted to zero, and the output value of the sensor under zero input state is measured and subtracted from subsequent measurements as an offset. By taking the average of a certain number of consecutive data points, the noise and interference in the sensor data can be effectively removed. In practical applications, random fluctuations caused by environmental factors, equipment vibration, external disturbances, etc. can be reduced to obtain a more stable and reliable signal. Data smoothing and filtering not only make the signal more stable, but also improve the response speed and accuracy of the system in real-time control, thereby avoiding over-adjustment due to data fluctuations. By correcting the sensor output and removing its inherent bias, the accuracy of the data can be improved.For example, by adjusting the zero point of the sensor and subtracting the zero drift of the sensor, the accuracy of the measured value in the no-input state is ensured. Through correction, the error of sensor measurement is reduced and the overall measurement accuracy of the system is improved, thereby providing more reliable data support for subsequent intelligent control decisions. By acquiring and processing sensor data in real time, the system can dynamically adjust the speed of the agitator to adapt to different mixing environments and needs. Intelligent real-time adjustment can make the mixing process more efficient, avoid over-mixing or under-mixing, and help improve product consistency and quality. The introduction of intelligent control algorithms and real-time monitoring systems can build a closed-loop feedback mechanism to monitor and adjust various parameters in real time during the mixing process. This feedback mechanism enables the system to automatically adjust parameters such as speed, mixing time, and feeding amount according to the current mixing state, forming an adaptive control strategy. By collecting and processing data in real time, it can respond quickly to various changes in the mixing process (such as temperature, pressure, concentration of thermal power generation combustion products, etc.), thereby optimizing control decisions and making each operation more in line with current actual needs. Through data correction and filtering processing, the system can make full use of the external environment or the sensor's own errors. It has stronger adaptability. Through real-time monitoring and intelligent control, the system can not only detect abnormal situations, but also perform self-correction according to the set feedback rules. Intelligent control improves the degree of automation of the production process, reduces manual intervention and monitoring costs, improves overall production efficiency, and thus reduces production costs. It eliminates the zero offset of the sensor and adjusts the sensitivity of the sensor so that its output is consistent with the actual value. According to the sensor characteristics, linear and nonlinear corrections are performed, and the corrected data is filtered to remove noise interference. The sensor may have deviations in the initial state. By eliminating the zero offset, the baseline value of the sensor output can be guaranteed to be accurate, thereby ensuring the accuracy of subsequent data. Sensitivity adjustment helps ensure that the sensor can provide accurate output within different measurement ranges, so that the system can reflect the actual state of the mixing process and avoid errors caused by insensitive or oversensitive sensor response. The output of many sensors is not completely linear with the actual physical quantity. Therefore, through linear or nonlinear correction, the difference between the sensor output and the actual value can be minimized to ensure that the control system makes decisions based on accurate data. Sensors are usually interfered with by noise, which affects the accuracy of the data. Through the filtering algorithm, noise can be effectively removed to ensure the clarity and availability of input data. By introducing real-time data acquisition and feedback mechanisms, the control system can be dynamically adjusted according to the information during the actual mixing process. By combining intelligent control algorithms, the speed of the agitator can be dynamically adjusted according to real-time monitoring data to achieve more accurate and efficient mixing control. Through intelligent algorithms and real-time data feedback, the system can adjust the speed and mixing mode according to the real-time environment and operating status.For example, in different stirring stages (such as mixing, dissolving, dispersing, etc.), the stirring speed can be adjusted specifically to ensure the best effect. Accurate real-time adjustment can not only ensure the stirring effect, but also avoid excessive or insufficient stirring, improve energy efficiency and material utilization, and reduce unnecessary waste.

[0114] Before step S5 of extracting key features of the combustion furnace stirring process by a data analysis method, the method includes:

[0115] S51. Use statistical methods to remove abnormal data points, scale the data to the same range for subsequent processing, interpolate missing data, and fill in gaps. Feature extraction is to extract parameters that can reflect the key characteristics of the mixing process from the original data. Based on the extracted features, a mathematical model is established for prediction and control. For linear data, the calculation is as follows:

[0116] y=β0+β1x1+β2x2+…+β n x n +ε;

[0117] Among them, y is the target variable, β n is the model parameter, x n is the characteristic parameter, ε is the error term;

[0118] S52. The calculation for nonlinear data is as follows:

[0119] y=f(W2·g(W1·x+b1)+b2);

[0120] Where W1 and W2 are weight matrices, y is the target variable, f is the activation function of the output layer, b1 and b2 are biases, and g is the activation function;

[0121] S53. Divide the dataset into a training set and a test set for model training and validation. Use the training set data to fit the model parameters, and use the test set data to evaluate the performance of the model.

[0122] As described in the above steps S51-S53, the dynamic characteristics of the system are described by nonlinear relationships. Data are mapped to high-dimensional space through kernel functions to construct classification or regression models. Complex nonlinear relationships are fitted through multi-layer neural networks. The uncertainty of the data is described through Gaussian processes, which is suitable for small sample data sets. Cross-validation: The generalization ability of the model is evaluated through cross-validation. Error analysis: Calculate model prediction errors, such as mean square error (MSE), mean absolute error (MAE), etc. Hyperparameter tuning: Adjust model hyperparameters through grid search, random search or Bayesian optimization. Model integration: Improve the prediction performance of the model through integrated learning methods (such as Bagging, Boosting). The above methods can effectively preprocess and extract features of the collected data, and establish mathematical models to achieve prediction and control of the mixing process. Statistical methods are used to remove abnormal data points and scale the data to the same range for subsequent processing. Missing data are interpolated to fill in the gaps. Feature extraction is to extract parameters that can reflect the key characteristics of the mixing process from the original data. According to the extracted features, a mathematical model is established. For prediction and control, the data set is divided into a training set and a test set for model training and verification. The training set data is used to fit the model parameters, and the test set data is used to evaluate the performance of the model. Removing abnormal data through statistical methods can effectively reduce noise interference, ensure data quality, and improve the accuracy of model predictions. Abnormal data may be caused by sensor failure, environmental changes, or data collection errors. Removing these data points helps to improve the reliability of subsequent processing and model training. Interpolation methods for missing data (such as linear interpolation, interpolation method, etc.) can maintain data continuity, avoid inaccurate or invalid models due to missing values, and further improve the stability of the model. Scaling the data to the same range can avoid certain features affecting the results during model training due to dimensional differences.For example, the numerical range of some features is very large, while others are smaller. After standardization, the influence of all features on the model is relatively balanced, which helps the algorithm converge better. After the data is scaled, the model training will become more efficient and can find the optimal solution in a shorter time. By extracting key features from the original data and providing real-time feedback, it can help the control system adjust the speed according to the current state of the mixing process. The introduction of this intelligent control algorithm can improve the accuracy and efficiency of the mixing process and realize dynamic adjustment to adapt to different working conditions and environmental changes. By establishing a mathematical model and using training set data for training, the system can learn the mixing process based on historical data. When the model is continuously verified and optimized in practical applications, it can continuously improve its accuracy and robustness. This autonomous learning ability makes the mixing process control more intelligent. Through precise prediction and control, the rotation speed can be dynamically adjusted according to the real-time mixing process data to reduce over-mixing or under-mixing, thereby improving production efficiency and product quality. By dividing the data set into a training set and a test set, the generalization ability of the model can be tested to ensure the performance of the model in practical applications. Therefore, it can not only improve the quality and efficiency of the mixing process, but also reduce human intervention, reduce operational risks, and ultimately improve the automation level and stability of the production process.

[0123] The step S7 of adjusting the stirring speed of the combustion furnace according to the real-time monitoring data includes:

[0124] S71. Adjust the stirring speed by using the control signal calculated by the control algorithm. The actuator receives the control signal, adjusts the speed of the stirring device, and feeds back the actual speed to the controller. The adjusted actual stirring speed is fed back to the controller to form a closed-loop control.

[0125] S72. Dynamically adjust the control signal based on the actual speed feedback to ensure that the mixing process is always in the best state; optimize the controller parameters through experiments and simulations to improve the control accuracy and stability of the system; debug the closed-loop control system under actual working conditions to ensure that it can adapt to different working conditions; and use the monitoring system to view the key parameters and control effects of the mixing process in real time;

[0126] S73. When the system is abnormal, the alarm mechanism is triggered to remind the operator to intervene.

[0127] The step S7 of dynamically adjusting the stirring speed according to the real-time parameter changes during the stirring process includes:

[0128] S74. Use the PID control algorithm to adjust the three parameters of proportion, integration, and differentiation to achieve precise control of the system. The calculation is as follows:

[0129]

[0130] Among them, u(t) is the control signal, that is, the adjusted stirring speed, e(t) is the error signal, K p , K i With K d are proportional, integral and derivative gains respectively, is the integral term, is the differential term.

[0131] As described in the above steps S71-S74, the present invention calculates a control signal according to the control algorithm and adjusts the stirring speed according to the control signal. The actuator receives the control signal, adjusts the speed of the stirring equipment, and feeds back the actual speed to the controller. The adjusted actual stirring speed is fed back to the controller to form a closed-loop control. Traditional stirring control methods usually use a preset speed value and cannot dynamically adjust the speed according to the real-time stirring process. After introducing control signal feedback and closed-loop control, the system can dynamically adjust the speed according to the data information collected in real time during the stirring process (such as the viscosity, temperature, stirrer load, etc. of the thermal power generation combustion material). This means that the stirring process can be accurately controlled according to the actual working conditions, avoiding the problem of over-stirring or under-stirring. Through closed-loop control and intelligent algorithms, the system can realize real-time The system monitors the stirring effect and automatically adjusts it based on the feedback signal. This precise feedback regulation mechanism can significantly improve the efficiency of the stirring process and avoid waste or uneven stirring caused by excessively fast or slow speeds in traditional methods. By dynamically adjusting the stirring speed, the system can optimize the use of energy. Under traditional control methods, the speed of the stirrer is often fixed, which may waste a lot of energy. However, through intelligent control algorithms, the system will adjust the speed according to actual conditions, reducing unnecessary energy waste. Energy conservation and emission reduction not only reduce production costs, but also conform to the trend of green production. The introduction of intelligent control algorithms and real-time monitoring mechanisms can make the entire stirring process more automated and intelligent. Through real-time monitoring of equipment status and the stirring process, the system can detect abnormal conditions early and issue fault warnings. For example, when the stirrer load is abnormal or the speed fluctuates, the system will automatically remind maintenance personnel to inspect and maintain it. This early warning mechanism can avoid production stoppages and losses caused by equipment failure, improve the operating reliability and service life of the equipment, dynamically adjust the control signal according to the actual stirring speed, and ensure that the stirring process is always in the best state. Through experiments and simulations, optimize the controller parameters, improve the control accuracy and stability of the system, and debug the closed-loop control system under actual working conditions to ensure that it can adapt to different working conditions. By real-time monitoring of the stirring process, the intelligent control system can adjust the stirring speed according to real-time feedback to ensure that the stirring is always in the best state. By dynamically adjusting the control signal, the closed-loop control system can respond to changes in the external environment or process conditions in real time, ensuring that the stirring system maintains a stable working state under variable working conditions and reducing instability or system oscillations. By optimizing the controller parameters through experiments and simulations, the system can automatically adjust the control strategy to adapt to different working conditions without manual intervention. This can significantly improve the adaptability and flexibility of the stirring system under various working conditions. Through the application of intelligent control algorithms, the stirring system can autonomously obtain and process real-time data, automatically adjust the speed or other control parameters, reduce the need for manual operation, improve the degree of automation, and reduce the impact of human factors on stirring quality. By intelligently adjusting the stirring speed,It can ensure the optimization of energy consumption during the mixing process. Compared with the fixed speed control method, dynamic speed adjustment helps to avoid over-mixing or under-mixing, thereby reducing unnecessary energy consumption and mechanical wear, and improving the energy efficiency and overall production efficiency of the mixing process. Traditional mixing control methods often lack real-time monitoring and feedback mechanisms, resulting in the inability to accurately understand the real-time situation of the mixing process. The intelligent control method collects data during the mixing process in real time (such as speed, temperature, pressure, uniformity of the mixture, etc.), and provides feedback and adjustments based on these data, so that the mixing process is always in the best state. This real-time feedback can not only improve the mixing accuracy, but also monitor the equipment status and detect potential faults in advance. Through the monitoring system, the key parameters and control effects of the mixing process can be viewed in real time. When the system is abnormal, the alarm mechanism is triggered to remind the operator to intervene. The three parameters of proportion, integration and differentiation are adjusted through the PID control algorithm. To achieve precise control of the system, by real-time monitoring of key parameters in the mixing process (such as temperature, pressure, viscosity, flow, etc.), the system can dynamically adjust the mixing speed according to the current situation. This flexible control method makes the mixing process more precise and can adapt to different process requirements and raw material changes without relying on fixed, preset speeds. The PID control algorithm can make high-precision adjustments to the mixing system based on real-time feedback to ensure process stability and avoid over-mixing or under-mixing. The proportional part adjusts the proportional relationship between output and deviation, the integral part eliminates continuous deviation, and the differential part makes predictive adjustments based on the deviation change rate, thereby achieving refined control. Through real-time monitoring and data acquisition, the system can monitor and record key parameters in the mixing process, reflect the system status in real time, and ensure the stability and consistency of the mixing process. Traditional mixing systems often rely on manually set fixed parameters or manually adjust the speed, and lack flexible adaptive capabilities. After introducing PID control algorithms and real-time data feedback, the system can automatically adjust the speed and other key parameters without human intervention, optimize production efficiency, and reduce human errors. By analyzing real-time data, the system can not only respond to abnormal situations, but also predict mixing needs based on historical data and trends, further optimize the mixing process, and improve overall production efficiency. Accurately controlling the mixing speed can reduce over-mixing or under-mixing and avoid unnecessary energy waste. At the same time, a reasonable mixing speed can improve production efficiency and make the production process more efficient. Through PID control, the system can reduce wear on equipment due to excessive mixing or improper operation, thereby extending the service life of the equipment and reducing maintenance costs. Through the integrated monitoring system, operators can remotely view key parameters and control effects in the mixing process, conduct real-time monitoring and fault diagnosis, which helps to improve the efficiency of the overall production process, product quality, and long-term maintainability of the equipment, while reducing production costs and equipment losses.
