[0005] In view of the above problems, this application provides a method, system and medium for intelligent speed regulation of mixers based on hydraulic stability.

[0006] The first aspect of this application provides an intelligent speed regulation method for a hydraulically stable mixer.

It should also be noted that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings, not all of them.

[0025] Example 1, as Figure 1 As shown, this application provides a hydraulically stable intelligent speed control method for mixers, which includes:

[0026] The fluid at the mixer inlet is monitored in real time to obtain a set of real-time fluid parameters. The real-time rotational speed of the mixer is then used to calculate the load on the mixer and determine the real-time load torque parameters.

[0027] Furthermore, the fluid at the mixer inlet is monitored in real time to obtain a real-time fluid parameter set. The real-time rotational speed of the mixer is then used to calculate the load on the mixer to determine the real-time load torque parameter. The method includes: continuously acquiring fluid pressure fluctuation signals through a pressure transmitter installed on the mixer inlet pipeline; performing mean filtering on the fluid pressure fluctuation signals to obtain the fluid pressure value; continuously acquiring fluid temperature fluctuation signals through a temperature sensor installed on the mixer inlet pipeline; calibrating and compensating the fluid temperature fluctuation signals to obtain the fluid temperature value; performing fluid physical property analysis based on the fluid temperature value to calculate the fluid viscosity value; and real-time sensing of the mixer's drive shaft to obtain the real-time rotational speed of the mixer. The load is then calculated based on the real-time rotational speed of the mixer combined with the fluid pressure value, the fluid temperature value, and the fluid viscosity value to obtain the real-time load torque parameter.

[0028] Specifically, a mixer typically consists of three parts: an inlet pipe, a mixing chamber, and an outlet pipe. Its working principle is based on fluid mechanics and mass and heat transfer principles. The rotation of the impeller generates shear force and turbulence, achieving thorough mixing of different fluid components. A pressure transmitter is installed at the mixer inlet pipe. This pressure transmitter is a sensor that converts fluid pressure signals into electrical signals. It continuously acquires fluid pressure fluctuation signals, obtaining real-time information on fluid pressure changes. The acquired fluid pressure fluctuation signals are then subjected to mean filtering. Mean filtering is a common signal processing technique that calculates the average value of the fluid pressure fluctuation signal within a certain time window to remove noise and interference, resulting in a more stable and accurate fluid pressure value. For example, the arithmetic mean of fluid pressure fluctuation signals acquired from 10 consecutive sampling points can effectively suppress periodic noise. After mean filtering, the obtained fluid pressure value accurately reflects the pressure state of the fluid at the mixer inlet. Simultaneously, a temperature sensor installed in the mixer inlet pipe continuously acquires the fluid temperature in the inlet pipe, obtaining fluid temperature fluctuation signals. Because temperature sensors are affected by changes in ambient temperature during actual use, leading to deviations in measurement results, calibration and compensation are performed on the collected fluid temperature fluctuation signals. For example, a high-precision ambient temperature reference sensor can be added near the temperature sensor's installation location to collect ambient temperature data in real time. Simultaneously, a temperature-error mapping table for the fluid temperature sensor is established using historical data. The measurement error correction amount for the fluid temperature in the current inlet pipe is then retrieved based on the real-time ambient temperature value and, combined with the fluid temperature fluctuation signal, is calculated using formula T. 校准 =T 原始 −ΔT(T 环境), where ΔT is the correction amount obtained from the lookup table, achieving dynamic compensation to obtain the final fluid pressure value. A standardized physical property database of common fluids, such as water, oil, and polymer solutions, is pre-constructed, storing viscosity-temperature experimental data of each fluid within a specific temperature range. By inputting the fluid medium in the current mixer inlet pipe, based on the fluid temperature value as input, the corresponding viscosity benchmark value is queried from the standardized physical property database. If the fluid is a non-Newtonian fluid, such as a shear-thinning fluid, a shear rate correction term calculated based on the real-time rotational speed is further superimposed. By analyzing the fluid physical properties of the corrected fluid temperature value, the corresponding fluid viscosity value is calculated, reflecting the magnitude of the fluid's internal resistance. The collected and calculated fluid pressure data, fluid temperature data, and fluid viscosity value are integrated to obtain a real-time fluid parameter set. The rotational speed of the mixer drive shaft is collected in real time by a speed sensor installed on the drive shaft to obtain the real-time mixer rotational speed. Then, the obtained real-time mixer rotational speed is combined with the fluid pressure value, fluid temperature value, and fluid viscosity value to perform load calculation, thereby determining the real-time load torque parameter. By monitoring the inlet fluid and calculating the load in real time, the current operating status and load of the mixer can be accurately obtained, thus providing accurate and reliable data support for the adaptive speed regulation of the mixer and improving mixing quality and production efficiency.

[0029] Furthermore, the real-time load torque parameter is obtained by calculating the load based on the real-time rotational speed of the mixer combined with the fluid pressure, fluid temperature, and fluid viscosity values. The method includes: cross-fusion of the real-time rotational speed of the mixer with the fluid pressure, fluid temperature, and fluid viscosity values; constructing a multi-dimensional operating condition feature vector based on the fusion result; introducing a historical multi-dimensional operating condition parameter set for multi-condition load calculation to obtain a calibration dataset; identifying the operating condition based on the multi-dimensional operating condition feature vector to determine the target operating condition category data; and using the target operating condition category data as an index to retrieve the calibration dataset to obtain the real-time load torque parameter.

[0030] Specifically, a data fusion algorithm is employed to cross-fuse the real-time mixer speed, fluid pressure, fluid temperature, and fluid viscosity values ​​obtained from the collected calculations. For example, by using a synchronization signal, the sampling timestamps of the real-time mixer speed, fluid pressure, fluid temperature, and fluid viscosity values ​​are aligned to the same time baseline. Then, fusion algorithms such as Kalman filtering and particle filtering are used to integrate multiple data of different types to obtain the fusion result. The fused dataset is represented as a vector form, forming a multi-dimensional operating condition feature vector. This multi-dimensional operating condition feature vector contains information from multiple dimensions, such as the real-time mixer speed, fluid pressure, fluid temperature, and fluid viscosity values, which can comprehensively reflect the operating status of the mixer under the current operating conditions. Historical multi-dimensional data of the mixer under different operating conditions is collected to form a historical multi-dimensional operating condition parameter set. This historical multi-dimensional operating condition parameter set includes mixer speed, fluid pressure, fluid temperature, and fluid viscosity values. Through experimental or simulation methods, the mixer is run under different operating conditions, and the corresponding load torque data is calculated to form a calibration dataset. Historical feature data is divided into multiple typical operating condition categories using K-means clustering, such as high viscosity-high speed and low pressure-variable temperature. Based on the constructed multi-dimensional operating condition feature vector, the Mahalanobis distance between the multi-dimensional operating condition feature vector and the center of each operating condition cluster is calculated in real time to determine the target operating condition category data. Then, using the target operating condition category as an index, the most similar historical feature vector is found by searching and matching from the calibration dataset using a nearest neighbor search algorithm. The corresponding operating condition load is directly output as the real-time load torque parameter, enabling fast and accurate acquisition of the real-time load torque parameter corresponding to the current operating condition category, thereby improving the accuracy and effectiveness of the mixer's adaptive speed control.

[0031] Set a target mixing quality index, perform mixing analysis on the real-time fluid parameter set, and determine the target mixing efficiency.

[0032] Furthermore, a target mixing quality index is set, and a mixing analysis is performed on the real-time fluid parameter set to determine the target mixing efficiency. The method includes: setting a target mixing quality index, where the target mixing quality index is the component uniformity or particle size distribution of the fluid at the mixer outlet; performing pressure and temperature fluctuation analysis based on the component uniformity, and setting pressure uniform fluctuation thresholds and temperature uniform fluctuation thresholds; performing viscosity analysis based on the particle size distribution, and setting a fluid viscosity threshold; comparing the fluid pressure value with the pressure uniform fluctuation threshold to calculate the pressure fluctuation amplitude; comparing the fluid temperature value with the temperature uniform fluctuation threshold to calculate the temperature fluctuation amplitude; comparing the fluid viscosity value with the fluid viscosity threshold to calculate the fluid viscosity state parameter; performing a mixing analysis based on the pressure fluctuation amplitude, the temperature fluctuation amplitude, and the fluid viscosity state parameter to obtain a mixing difficulty analysis result; and matching the mixer performance spectrum according to the mixing difficulty analysis result to determine the target mixing efficiency.

[0033] Specifically, based on the mixing process requirements, target mixing quality indicators are set. These indicators refer to the mixing quality standards that the fluid exiting the mixer should achieve, including component uniformity or particle size distribution. Component uniformity reflects the evenness of the distribution of each component in the mixed fluid, while particle size distribution reflects the size distribution of particles in the mixed fluid. When using component uniformity as the target mixing quality indicator, pressure fluctuations can cause changes in fluid turbulence intensity, thus affecting the component diffusion rate. Temperature fluctuations can change fluid density and surface tension, indirectly interfering with mixing uniformity. Therefore, pressure and temperature fluctuations are analyzed, and based on historical data analysis results and the mixer's process requirements, pressure uniformity fluctuation thresholds and temperature uniformity fluctuation thresholds are set as boundary conditions for stable operation. When using particle size distribution as the target mixing quality indicator, fluid viscosity analysis is performed. Since fluid viscosity affects particle dispersion, excessively high viscosity can hinder particle movement and lead to agglomeration. Therefore, a fluid viscosity threshold is set to ensure effective particle dispersion. The fluid pressure, temperature, and viscosity values ​​are then compared with preset pressure uniform fluctuation thresholds, temperature uniform fluctuation thresholds, and viscosity thresholds, respectively, to calculate the pressure fluctuation amplitude, temperature fluctuation amplitude, and fluid viscosity parameters. A mixing analysis is then performed based on these parameters to assess the difficulty encountered during mixing, yielding a mixing difficulty analysis result. This result reflects the ease with which the mixer achieves the target mixing quality under current operating conditions. For example, the pressure fluctuation amplitude, temperature fluctuation amplitude, and fluid viscosity parameters are normalized and mapped to a unified numerical range. Then, weighting coefficients are assigned based on the influence of each parameter on the mixing difficulty. The normalized parameters are multiplied by their corresponding weights and summed to obtain the mixing difficulty analysis result. A result closer to 1 indicates higher mixing difficulty, while a result closer to 0 indicates ideal mixing conditions, meaning that multiple parameters do not exceed the thresholds. Using real-time fluid parameter sets and mixing difficulty analysis results as query criteria, a matching search is performed in a pre-built mixer performance map database. By calculating the Euclidean distance or cosine similarity between the real-time fluid parameters and mixing difficulty and the historical operating condition records in the mixer performance map database, all historical mixing efficiency values ​​that can achieve the target mixing quality index under the same or similar fluid parameters and mixing difficulty are found. From all historical mixing efficiency values ​​that meet the conditions, the efficiency value with the smallest value is selected and determined as the target mixing efficiency. The mixer performance map is a collection of mixer performance data under different operating conditions, reflecting the mixing efficiency of the mixer under different operating conditions.By setting target mixing quality indicators and conducting mixing analysis, the degree of difficulty encountered in the mixing process can be accurately assessed, thereby determining the target mixing efficiency. This provides an accurate and reliable basis for the speed control of the mixer, enabling the mixer to automatically adjust to the optimal operating state under different working conditions in order to achieve or approach the target mixing efficiency.

[0034] Speed ​​regulation calculations are performed based on the real-time load torque parameters and the target mixing efficiency to generate a speed regulation control signal, which includes the target speed value.

[0035] Furthermore, a speed regulation strategy database is constructed. The real-time load torque parameter and the target mixing efficiency are used as input conditions and synchronized to the speed regulation strategy database for multi-condition matching queries to generate a recommended speed value. The recommended speed value is converted into a standard electrical signal, and the mixer is speed-regulated using the standard electrical signal to generate an initial speed regulation signal. Based on the initial speed regulation signal, historical speed values ​​of adjacent cycles are retrieved according to the speed cycle. The difference between the recommended speed value and the historical speed value is compared to verify whether the speed difference exceeds a preset speed limit. When the speed difference exceeds the preset speed limit, the recommended speed value is restricted to within the historical speed value to generate a target speed value. When the speed difference does not exceed the preset speed limit, the recommended speed value is used as the target speed value.

[0036] Specifically, the mixer is operated under various operating conditions, collecting multiple load torque parameters and mixing efficiency values, and recording the stable operating speed point for each condition. The load torque parameters and target mixing efficiency are used as a joint primary key to construct raw data pairs. After cleaning and classification, a speed control strategy database is built. This database contains a set of data on the mixer's load torque parameters, target mixing efficiency, and corresponding speed values ​​under different operating conditions. Real-time load torque parameters and the target mixing efficiency are used as input conditions and synchronized to the speed control strategy database for multi-condition matching queries to obtain recommended speed values. These recommended speed values ​​are then converted into standard electrical signals according to the PWM duty cycle versus speed calibration curve. These standard electrical signals are signals that can be recognized and executed by the mixer's speed control driver, and are either voltage or current signals. The standard electrical signals are input to the mixer's speed control driver to adjust the mixer's speed, generating an initial speed control signal. Based on this initial speed control signal, historical speed values ​​from adjacent cycles are retrieved according to the speed cycle, where the speed cycle refers to the time interval for adjusting the mixer's speed, for example, recording a speed value once per minute. Then, the difference between the recommended speed value and the historical speed value is compared. The calculation results verify whether the speed difference exceeds the preset speed limit. The preset speed limit is the maximum allowable speed variation range set according to the mechanical characteristics and process requirements of the mixer, used to prevent damage to the mixer caused by excessively rapid speed changes. When the difference does not exceed the preset speed limit, the recommended speed value is directly output as the target speed value. When the speed difference exceeds the preset speed limit, speed limiting processing is used to restrict the recommended speed value to within the historical speed value, generating the target speed value. For example, if the preset speed limit is 2 rad / s, the historical speed value is 9 rad / s, the recommended speed value is 10 rad / s, and the speed difference is 1 rad / s, which does not exceed the preset speed limit. The recommended speed value is directly set as the target speed value, and the target speed value is 10 rad / s. If the recommended speed value is 12 rad / s, the historical speed value is 8 rad / s, and the preset speed limit is 2 rad / s, then the target speed value should be limited to 10 rad / s.

[0037] By constructing a speed regulation strategy database and using multi-condition matching queries, suitable recommended speed values ​​can be found quickly and accurately. By retrieving historical speed values ​​and comparing the differences, it is ensured that speed changes are within a safe range, preventing damage to the mixer. Furthermore, the generated target speed value can drive the mixer to perform precise speed regulation, ensuring that the mixer achieves the target mixing efficiency under different operating conditions, thereby improving mixing quality and production efficiency.

[0038] Furthermore, the method for constructing the speed regulation strategy database, using the real-time load torque parameters and the target mixing efficiency as input conditions, and synchronizing them to the speed regulation strategy database for multi-condition matching queries to generate recommended speed values, includes: retrieving multiple load torque parameters and multiple mixing efficiencies of the mixer under different operating conditions; conducting operational tests based on the multiple load torque parameters and multiple mixing efficiencies to extract stable operating speed points; integrating the multiple load torque parameters and multiple mixing efficiencies according to the stable operating speed points to construct original data pairs; cleaning and classifying the original data pairs, using the multiple load torque parameters and multiple mixing efficiencies as joint primary keys to construct the speed regulation strategy database; using the real-time load torque parameters and the target mixing efficiency as input conditions to form a query vector; traversing the speed regulation strategy database according to the query vector to compare the joint primary keys and obtain comparison results; calculating Euclidean distance based on the comparison results, and determining the recommended speed value based on the distance parameter.

[0039] Specifically, the mixer is operated under various operating conditions to collect multiple load torque parameters and mixing efficiency values. The stable operating speed point for each operating condition is recorded. The stable operating speed refers to the speed at which the mixer can operate stably and achieve the target mixing efficiency under a specific operating condition. Based on the collected data, the stable operating speed point, load torque parameters, and mixing efficiency are integrated to construct raw data pairs. Each data pair contains a load torque value, a mixing efficiency value, and a corresponding stable operating speed value. The raw data pairs are cleaned to remove outliers, ensuring data accuracy and consistency. Then, the K-means clustering algorithm is used to merge and classify the cleaned data according to similar operating conditions. The load torque parameters and mixing efficiency are used as a joint primary key to construct a speed regulation strategy database. The joint primary key ensures that each combination of load torque and mixing efficiency corresponds to a recommended speed value. After the speed regulation strategy database is constructed, real-time load torque parameters and target mixing efficiency are used as input conditions to form a query vector. This query vector contains the load torque parameters and mixing efficiency under the current operating condition and is used to query the speed regulation strategy database. The speed regulation strategy database is traversed according to the query vector, and the composite primary key is compared to obtain the comparison results. If a record in the database completely matches the query vector, the corresponding recommended speed value is directly obtained. If no record completely matches, Euclidean distance is calculated based on the comparison results. Euclidean distance is a method used to measure the distance between two points and can be used to evaluate the similarity between the query vector and the records in the database. By calculating the Euclidean distance between the query vector and each record, the record with the closest distance is found, thereby determining the recommended speed value.

[0040] By constructing a speed regulation strategy database and using multi-condition matching queries, suitable recommended speed values ​​can be found quickly and accurately. Simultaneously, through Euclidean distance calculation, the closest recommended speed value can be found even when no perfectly matching record exists. This allows the mixer to automatically adjust to its optimal operating state under different working conditions, improving the accuracy and reliability of the mixer's speed control, thereby enhancing mixing quality and production efficiency.

[0041] The target speed value is executed to drive the mixer to adjust its speed. The speed control result is then used to verify the speed of the real-time fluid parameter set. Dynamic speed control commands are then formulated to adaptively adjust the speed of the mixer.

[0042] Furthermore, the target speed value is used to drive the mixer to adjust its speed, and the speed control result is used to verify the speed of the real-time fluid parameter set. A dynamic speed control command is then formulated. The method includes: executing the target speed value to drive the mixer to adjust its speed; collecting data at the mixer inlet based on the speed control result to obtain a speed-adjusting fluid parameter set; comparing the speed-adjusting fluid parameter set with the real-time fluid parameter set, verifying the speed based on the comparison result, and generating speed adjustment effect data; evaluating the effectiveness of the target speed value based on the speed adjustment effect data, performing scheduling analysis based on the evaluation result, and setting a recommended speed adjustment step size; performing a reciprocating speed adjustment analysis according to the recommended speed adjustment step size to determine the speed adjustment cycle; decomposing the target speed value and the recommended speed adjustment step size according to the speed adjustment cycle to obtain a continuous speed adjustment command; and associating and integrating the continuous speed adjustment commands to formulate the dynamic speed control command.

[0043] Specifically, the target rotational speed is converted into a corresponding electrical signal by a speed-regulating driver. The speed-regulating driver adjusts the motor speed according to the target rotational speed to ensure the mixer operates at the target speed. After the target rotational speed is achieved, parameters such as fluid pressure, fluid temperature, and fluid viscosity are monitored and collected in real time in the mixer inlet pipeline to obtain a speed-regulating fluid parameter set. This set refers to the real-time parameter set of the fluid in the mixer inlet pipeline at the target rotational speed, reflecting the mixer's operating state at that speed. Then, the speed-regulating fluid parameter set is compared and analyzed with the real-time fluid parameter set to calculate the changes in fluid pressure, temperature, and viscosity, obtaining a comparison result. The mixer's rotational speed is verified based on the comparison result, generating speed regulation effect data. This data reflects the changes in fluid parameters after speed regulation. Based on the parameter changes in the speed regulation effect data, a weighted scoring algorithm is used to quantitatively evaluate the effectiveness of the target rotational speed. In the weighted scoring algorithm, different weights are assigned to each parameter according to their importance to the mixing effect; for example, if fluid pressure has a greater impact on mixing quality, it is given a higher weight. By calculating the deviations of each parameter's change from a preset threshold and multiplying them by their respective weights, a comprehensive score is obtained. If the comprehensive score exceeds the preset threshold, the speed regulation is deemed effective, and the current speed is maintained. If the score is below the preset threshold, it indicates that the speed regulation effect has not met expectations. Using a fuzzy inference engine, based on the evaluation results and considering factors such as the mixer's operating status, historical data, and process requirements, a recommended speed regulation step size is dynamically set. The recommended speed regulation step size refers to the suggested speed adjustment range under the current operating conditions. The fuzzy inference engine handles uncertainty and fuzziness through fuzzy logic, enabling flexible adjustment of the recommended speed regulation step size according to different operating conditions. This achieves adaptive speed regulation of the mixer, ensuring efficient and stable operation of the mixer under various conditions. Speed ​​regulation reciprocating analysis is performed according to the recommended speed regulation step size. By simulating the speed regulation process under different step sizes, the mixer response is analyzed, including the smoothness of speed change, the time required to reach the target speed, and the vibration of the mixer during the speed regulation process. A comprehensive analysis of the speed regulation response speed and mixer stability is conducted to determine an optimal speed regulation cycle. The speed regulation cycle refers to the time interval for speed regulation verification at different speeds, used to control the frequency of the speed regulation process and prevent parameter fluctuations due to an excessively short cycle. After determining the speed regulation cycle, the target speed value is decomposed into continuous speed regulation commands according to the recommended step size. For example, if the speed regulation cycle is 1 second, the target speed is 10 rad / s, the current speed is 9 rad / s, and the recommended speed regulation step size is 0.5 rad / s, then the speed regulation process can be decomposed into the following steps: 1st second: Adjust the speed from 9 rad / s to 9.5 rad / s. 2nd second: Adjust the speed from 9.5 rad / s to 10 rad / s. After each adjustment, wait 1 second to ensure speed stability. Continuous speed control commands refer to a sequence of commands that gradually adjust the speed within a speed control cycle.By integrating various instructions through timestamp association, a dynamic speed control command containing rotational speed, execution time, and step size is generated to guide the mixer's speed adjustment process. This dynamic speed control command enables adaptive speed regulation of the mixer, achieving precise matching between the mixer's rotational speed and the fluid state.

[0044] By executing target speed values ​​to drive the mixer through speed regulation and verifying the speed regulation effect, it is possible to evaluate in real time whether the speed regulation has achieved the expected mixing effect. Based on the speed regulation effect data, effectiveness evaluation and scheduling analysis can be performed to dynamically adjust the speed regulation step size and speed regulation cycle, ensuring that the mixer achieves optimal operating conditions under different operating conditions. By generating continuous speed regulation commands and formulating dynamic speed regulation commands, smooth adaptive speed regulation of the mixer can be achieved, thereby improving the mixing quality and production efficiency of the mixer.

[0045] Furthermore, the speed-regulating fluid parameter set is compared and analyzed against the real-time fluid parameter set in reverse. Speed ​​verification is performed based on the comparison results to generate speed regulation effect data. The method includes: retrieving the speed-regulating fluid pressure, temperature, and viscosity values ​​based on the speed-regulating fluid parameter set; retrieving the fluid pressure, temperature, and viscosity values ​​based on the real-time fluid parameter set; calculating the absolute value of the change by comparing the speed-regulating fluid pressure, temperature, and viscosity values ​​with the fluid pressure, temperature, and viscosity values; setting an expected threshold for the change; comparing the absolute value of the change with the expected threshold; if the absolute value of the change is less than or equal to the expected threshold, the speed regulation control result is determined to meet the expected parameters, and the speed-regulating fluid parameter set is verified for stability to generate the speed regulation effect data; if the absolute value of the change is greater than the expected threshold, the speed regulation control result is determined to have failed to meet the expected parameters, and the speed-regulating fluid parameter set is verified for abnormal fluctuations to generate the speed regulation effect data.

[0046] Specifically, after setting the target speed, data is collected at the mixer inlet to obtain a set of speed-regulating fluid parameters. Based on this set, the speed-regulating fluid pressure, temperature, and viscosity values ​​are retrieved. Simultaneously, the fluid pressure, temperature, and viscosity values ​​from the real-time fluid parameter set are retrieved. These values ​​are then compared with those from the real-time set, and the absolute value of the change in each parameter is calculated—the absolute difference between the parameter value after speed regulation and the parameter value before speed regulation. For example, the absolute value of the difference between the speed-regulating fluid pressure and the real-time fluid pressure is represented as |ΔP|, the absolute value of the difference between the speed-regulating fluid temperature and the real-time fluid temperature is represented as |ΔT|, and the absolute value of the difference between the speed-regulating fluid viscosity and the real-time fluid viscosity is represented as |Δη|. Based on the mixer's process requirements and speed regulation target, the expected threshold for the change in each parameter is determined. For example, set the pressure change threshold to P. th The threshold for temperature change is T. th The viscosity change threshold is η th The expected threshold for the change in parameters is used to determine whether the parameter changes after speed regulation are within the allowable range. The absolute value of the change is compared with the expected threshold. If the absolute value of the change in all parameters is less than or equal to the corresponding expected threshold, the speed regulation control result is determined to meet the expected parameters. Simultaneously, the stability of the speed regulation fluid parameter set is verified by continuously monitoring changes in fluid parameters to ensure that the fluid parameters remain stable over a period of time, generating speed regulation effect data. If the absolute value of the change in any parameter is greater than the corresponding expected threshold, the speed regulation control result is determined to have failed to meet the expected parameters. Statistical analysis methods, such as moving average and standard deviation, are used to verify abnormal fluctuations in the speed regulation fluid parameter set, analyze whether abnormal fluctuations exist, and generate speed regulation effect data. This data includes information such as the parameter changes after speed regulation, whether they meet the expected parameters, and whether abnormal fluctuations exist.

[0047] By comparing the fluid parameters before and after speed regulation, calculating the absolute value of the change, and comparing it with the expected threshold of the change, we can accurately assess whether the speed regulation has achieved the expected mixing effect, thereby improving the accuracy and reliability of mixer speed regulation control, ensuring that the mixer can achieve the best operating state under different working conditions, improving mixing quality and production efficiency, while ensuring hydraulic stability.
