[0024] The drift calibration module includes: The temperature difference detection submodule uses a temperature sensor to acquire data on the fluctuation trends of the sample injection chamber temperature and the ambient temperature, analyzes the trajectory of their changes, calculates the direction of temperature difference change, and establishes the temperature difference change range by combining the amplitude and direction of temperature difference change within each detection cycle. The temperature difference detection submodule uses a temperature sensor to collect the temperature values inside the sample injection chamber and the external environment during the electrolysis process. The collection interval is set to once every 10 seconds, and 6 sets of data are collected continuously in each cycle, denoted as . ( (Representing the acquisition time), for example, the injection chamber temperature during the first acquisition cycle is recorded as follows: , , , , , The ambient temperatures were recorded as follows: , , , , , Based on the above data, trend analysis was performed on the temperature change trajectory. Using the acquisition time as the x-axis and temperature as the y-axis, temperature change curves for the injection chamber and the environment were plotted. By observing the trend of these curves and comparing the temperature change trajectories of the two, it was determined that the overall temperature trajectory of the injection chamber showed an upward trend. For example... If similar calculated values are continuously positive, then the trend is upward. Simultaneously, analyze the ambient temperature curve to identify the upward trend of the ambient temperature trajectory, such as... The continuous value is positive. Further calculations are performed to determine the direction of temperature difference change between the injection chamber and the ambient temperature. Calculation, for example If the continuous temperature difference value changes All are positive values, for example Multiple consecutive positive values indicate a continuously widening temperature difference trend. Continuous calculations determine the trend of change, and combine each The range of temperature difference variation is established as described above. If the temperature range within this collection period is 1.8℃-2.1℃, then 1.8℃ and 2.1℃ are used as the endpoints of the interval to generate the temperature difference range.
[0025] The synchronization determination submodule evaluates the trend of temperature synchronization deviation within a continuous sampling period based on the temperature difference change range. Combining the duration and direction of deviation, it judges the delayed response behavior of the injection chamber, analyzes the continuity and consistency of the synchronization deviation, and generates synchronization deviation parameters. The specific formula for determining the delayed response behavior of the injection chamber is as follows: ; Calculate the trend index of synchronization deviation; in, As a trend indicator of synchronization deviation, This represents the normalized value of the injection chamber temperature collected during the i-th period. The normalized value of the ambient temperature collected during the i-th period is... This represents the normalized value of the injection chamber temperature collected during the (i-1)th cycle. The normalized value of the ambient temperature collected during the (i-1)th period. Let be the temperature-normalized stability constant. For symbolic functions, Let be the directional weight corresponding to the direction of temperature change within the i-th period. The total number of sampling periods. This is the index number of the current sampling period. This is the index number of the previous sampling period.
[0026] formula: ; Detailed explanation of the formula and its calculation derivation: The formula is used to calculate the continuous consistency trend of temperature synchronization deviation, and the results are used to determine the continuity and significance of the influence of temperature drift trend on manganese electrolysis concentration measurement. Parameter meanings and settings: The normalized value of the injection chamber temperature collected in the i-th cycle is obtained by collecting actual injection chamber temperature data in real time and then normalizing it. The monitoring temperature in the second cycle is set to 35.6 degrees Celsius, and the normalization interval is set to the lowest actual monitoring value of 20 degrees Celsius and the highest actual monitoring value of 40 degrees Celsius. After normalization... ; The normalized value of the ambient temperature collected in the i-th period is calculated by monitoring the actual ambient temperature, which is 30.4 degrees Celsius in the same period. ; To prevent the denominator from being zero, the normalized value of the temperature stability constant is set to 0.01. This is a sign function used to determine whether the direction of the temperature difference in the current cycle is consistent with that in the previous cycle; The weight is the direction of temperature change in the i-th period. The weight standard is graded according to the magnitude of the absolute value of the temperature difference change. The weight value is set by the fluctuation range detected on site. The weight is 0.8 for below 0.2, 1.0 for 0.2-0.5, and 1.2 for above 0.5. Here, the absolute value of the temperature difference in the second period is |0.78-0.52|=0.26, corresponding to a weight of 1.0. To represent the total number of sampling periods, we set n=4; The monitoring sampling data is set as follows (all are normalized values): Period 1: , Weight 0.8; Second period: , Weight 1.0; 3rd period: , Weight 1.0; 4th period: , Weight 1.2; Substitute the parameters into the formula to calculate: Cycle 2: ; ; ; 3rd cycle: ; ; ; 4th cycle: ; ; ; The formula is to take the average: ; The result of 0.1820 indicates that the temperature synchronization deviation of the current cycle is relatively consistent. A value greater than 0 indicates that the temperature drift direction is consistent for most cycles and the change range is within the normal monitoring range. This trend value is used to generate the synchronization deviation parameter, which can provide a quantitative reference for subsequent automatic compensation or warning logic.
[0027] The response correction submodule calculates the correspondence between the degree of deviation and the difference in ion response in the concentration curve based on the synchronization deviation parameter, and corrects the current period concentration reading by the ratio between temperature difference change and concentration fluctuation, generating a concentration calibration value. The response correction submodule analyzes the correspondence between the synchronization deviation parameter and the ion concentration curve based on the synchronization deviation parameter, using the actual measured ion concentration data as the analysis object, such as the concentration data points of nickel ions continuously measured during the injection process. ( Representing the Using the detection time points as the analysis data, assuming that the concentration was measured at each of the 5 sampling points, the data is analyzed at each of the 5 detection time points. , , , , The synchronization deviation parameters of the temperature difference changes at each concentration point and the corresponding time point are calculated accordingly, such as the time point. The corresponding temperature difference is 2.1℃. A pre-set concentration correction reference value is invoked. When the temperature difference is between 2.0℃ and 2.2℃, the corresponding concentration correction coefficient is set to 0.95. This coefficient is pre-set based on actual production process experience. This correction coefficient is multiplied by the measured concentration point, for example, to obtain the corrected concentration. Similar calculations are performed sequentially for all concentration points to obtain the corrected concentration values for each point. A corrected concentration curve is then established. The corrected concentration curve data for the current period is retrieved, and the average correction magnitude for each concentration point is calculated. For example... The average correction margin is the current periodic concentration calibration value.
[0028] The structure matching module includes: The period comparison submodule obtains the concentration calibration value, collects the period of lattice spacing change during the deposition process, obtains the time frequency of impurity ion concentration fluctuation, compares the lattice spacing period and the frequency difference of each impurity ion concentration fluctuation, analyzes the consistency of period changes, and generates period matching differences. The periodic comparison submodule acquires concentration calibration values, specifically corrected concentration data of multiple impurity ions during electrolysis. Real-time data of the crystal lattice spacing during deposition is continuously acquired using an X-ray diffractometer; for example, the lattice spacing measured in six consecutive measurements is... , , , , , Calculate the change in lattice spacing between every two consecutive measurement points. For example, calculate the change from the first measurement to the second measurement. The process involves sequentially calculating the changes in lattice spacing to establish periodic data. A mass spectrometer is used to simultaneously measure the concentration fluctuation frequency of impurity ions, such as nickel ions. The interval between the highest concentration points within a period is defined as one fluctuation cycle. For example, the intervals between concentration peaks are 3 minutes, 3.2 minutes, and 3.1 minutes. The lattice cycle is compared with the nickel ion fluctuation cycle one by one. The cycle matching ratio is obtained by dividing the lattice cycle by the impurity ion cycle. A cycle matching is considered to occur when the matching ratio is between 0.95 and 1.05. For example, the matching ratio between a lattice cycle of 3.05 minutes and a nickel ion cycle of 3 minutes is 3.05 ÷ 3 = 1.017, satisfying the cycle matching condition. Multiple matching ratios are summarized and analyzed to calculate the matching difference. If the matching difference is between 0.95 and 1.05, the cycle matching difference is considered small; if it exceeds this range, the difference is considered large, generating a cycle matching difference.
[0029] The synchronization analysis submodule determines the temporal synchronization correlation between the structural period and the fluctuation of impurity ion concentration based on the period matching difference, filters period segments with consistent changing trends, and establishes the correlation between the structural period and the fluctuation of ion concentration by combining the structural period synchronization parameters, thereby generating structural synchronization parameters. The synchronous analysis submodule analyzes data based on period matching differences, using period groups with matching differences close to 1 as the base data. For example, it selects three data groups with period matching differences of 1.017, 0.998, and 1.004, and sequentially calls up the period data of lattice spacing and the fluctuation frequency of impurity ion concentration within the corresponding period group. Using the time coordinates corresponding to the start and end points of lattice changes within the period data as a benchmark, it determines whether the peak occurrence time of impurity ion concentration fluctuation falls within the start and end time range of the lattice period data. If the start and end time of the lattice period is 0 to 3.05 minutes, and the peak occurrence time of impurity ion concentration is 2.95 minutes, then it is judged... If the fluctuation time of impurity ion concentration is within the lattice period range, repeat the above steps to judge each set of data one by one, record the results of each set of judgments, and screen out the period groups in which the occurrence time of all impurity ion peaks falls within the lattice period range. For example, in a group with a period difference of 1.004, the lattice period range is 0 to 3.10 minutes, and the impurity ion peak is at 3.05 minutes, which falls completely within the lattice period range. Determine the structural period synchronization parameter by the proportion of the number of screened period groups to the total number of period groups. When this proportion exceeds 80%, it is confirmed that the structural period and impurity ion fluctuations have strong synchronization, and the structural synchronization parameter is established.
[0030] The influence identification submodule analyzes the trend of impurity ion concentration fluctuations on crystal deposition configuration changes based on structural synchronization parameters, identifies the influence relationship of each impurity ion concentration fluctuation on the deposition structure, and generates impurity response information. The specific formula for identifying the influence of concentration fluctuations of each impurity ion on the deposition structure is as follows: ; Calculate the impact intensity value; in, Let be the intensity value of the influence of the k-th impurity ion on the crystal deposition configuration. This is the normalized value of the concentration variation of the k-th impurity ion in the j-th lattice period. Let be the difference between the frequency of the concentration fluctuation of the k-th impurity ion and the frequency of the spacing fluctuation in the j-th lattice period. This is the normalized value of the spacing offset of the structurally stable region caused by the k-th impurity within the j-th lattice period. This is the normalized value of the grain arrangement perturbation value in the lattice distortion region caused by the k-th impurity within the j-th lattice period. The lattice period number, Number the impurity types. This represents the total number of cycles.
[0031] formula: ; Detailed explanation of the formula and its calculation derivation: The formula is used to calculate the intensity of the influence of each impurity ion on the crystal deposition configuration, and the results are used to determine the effect of impurity fluctuations on the deposition structure. Parameter meanings and settings: Let be the intensity value of the influence of the k-th impurity ion on the crystal deposition configuration. This is the normalized value of the concentration variation of the k-th impurity ion in the j-th lattice period. The value is obtained by normalizing the original value of the impurity concentration collected in real time by the ion concentration monitor and the value of the normalized value with the maximum concentration variation range in the same period. It is the difference between the concentration fluctuation frequency of the k-th impurity ion and the structural spacing fluctuation frequency in the j-th lattice period. The impurity fluctuation frequency is obtained by extracting the main peak from the high-frequency sampled concentration time series signal. This is the normalized value of the spacing shift of the structurally stable region caused by the k-th impurity within the j-th lattice period. The data is obtained by quantitatively measuring the lattice spacing change using an X-ray diffractometer. The normalized value of the grain arrangement perturbation value in the lattice distortion region caused by the k-th impurity in the j-th lattice period is obtained by statistical analysis of grain rearrangement in the distortion region using high-resolution electron microscopy. The total number of cycles is set to 5 cycles for lattice structure sampling and monitoring records. The lattice period number is taken from 1 to 5. Impurity types are numbered, with copper impurities numbered 1; the first cycle is defined as follows: , , , Second cycle: , , , , 3rd cycle: , , , , 4th cycle: , , , , 5th cycle: , , , ; Substitute the parameters into the formula to calculate: ; ; ; The results show that the influence intensity of copper impurities in the lattice structure deposition process of this batch is 0.0436, which represents the combined normalized influence of copper impurity fluctuations and structural disturbances. Corresponding to the impurity response information, it can be used to assess the risk contribution of copper impurities to the deposited structure in the quality prediction system.
[0032] The process parameter inversion module includes: The periodic analysis submodule calls the impurity response information, analyzes the element concentration trend in the residual liquid at the end of each period, obtains the time position of each raw material addition, statistically analyzes the concentration change range of impurities within the period span, calculates the concentration fluctuation range within each period, and generates the periodic concentration range. The cycle analysis submodule calls the impurity response information, which is the data on the influence of different impurity ions on the crystal lattice established in the previous steps. It selects the concentrations of multiple impurity ions, such as nickel and copper ions, as the analysis objects. At the end of each electrolysis cycle, it collects the concentration data of nickel and copper ions in the residual liquid. For example, at the end of a certain cycle, the nickel ion concentration is measured to be 3.8 mg / L and the copper ion concentration is 2.4 mg / L. It also records the concentration values of the same ions from the previous cycle, which are 3.2 mg / L for nickel ions and 1.9 mg / L for copper ions. It calculates the changing trend of each impurity ion concentration, specifically by subtracting the concentration from the previous cycle from the current cycle concentration. For example, nickel ion concentration is 3.8 mg / L - 3.2 mg / L = 0.6 mg / L, and copper ion concentration is 2.4 mg / L - 1.9 mg / L = 0.5 mg / L. It then calls the raw material addition control system to obtain the raw material addition time and records the corresponding electrolytic voltage. The starting point and position of the feed addition in the tank are determined, for example, the feed addition starts at the 10th minute and ends at the 15th minute of this cycle. This clarifies the temporal range of the cycle span. Based on the impurity concentration data of two consecutive cycles, the concentration fluctuation range of each ion within each cycle is statistically analyzed. Specifically, it is calculated by the difference between the maximum and minimum concentration values measured in each cycle. For example, in the current cycle, the maximum nickel ion concentration is 4.0 mg / L and the minimum is 3.0 mg / L, with a fluctuation range of 4.0 mg / L - 3.0 mg / L = 1.0 mg / L. Based on this, the fluctuation range of copper ions is calculated to be 0.8 mg / L. The fluctuation range of each ion is recorded. Based on the data recording of the concentration fluctuation range in multiple cycles, the concentration fluctuation range of each ion in this cycle is determined. For example, the fluctuation range of nickel ions is 3.0 mg / L - 4.0 mg / L, and the fluctuation range of copper ions is 1.9 mg / L - 2.7 mg / L, thus generating the cycle concentration range.
[0033] The interval filtering submodule filters concentration segments with consistent fluctuation directions based on the periodic concentration interval. Combining the impurity concentration change trend parameter, it identifies concentration change segments consistent with the periodic fluctuation, extracts fluctuation consistency markers, and generates consistent concentration segments. The interval filtering submodule, based on the periodic concentration intervals and the concentration data of multiple recorded periods, calls the periodic concentration interval data of impurity ions such as nickel ions and copper ions, and determines the direction of concentration fluctuation of impurity ions period by period, using the order in which the maximum and minimum concentration values occur as the basis. For example, if the maximum concentration value of nickel ions in period 1 occurs in the later part of the period, while the minimum concentration value occurs in the earlier part of the period, then the fluctuation trend of nickel ions in that period is determined to be an upward trend. Similar judgments on the fluctuation trend are performed for each ion in multiple periods, comparing whether the ion concentration fluctuation trend is consistent across multiple consecutive periods. To ensure consistency, the standard for consistent fluctuation direction is that the fluctuation direction of impurity ions is exactly the same within three consecutive periods. For example, if the concentration of nickel ions increases in consecutive periods 1, 2, and 3, and the concentration of copper ions increases in periods 1 and 2 but decreases in period 3, then nickel ions meet the standard for consistent fluctuation direction, while copper ions do not. All concentration fluctuation data segments that meet the standard for consistent fluctuation direction are filtered, and the concentration values in each segment are marked. For example, the concentration segment of nickel ions from period 1 to period 3 is recorded as the consistent concentration segment. This marked segment is associated with the impurity concentration change trend parameter to generate the consistent concentration segment.
[0034] The path determination submodule calls the consistency concentration segment, combines the raw material addition time, current change direction and temperature change area, performs path determination on the initial concentration behavior of impurities in the concentration change segment, analyzes the ratio and trend of each parameter, establishes the concentration value corresponding to the diffusion path start point, and generates the diffusion start point concentration. The path determination submodule calls the consistency concentration segment, using the recorded raw material addition time period, current change direction, and temperature change area as a basis to compare the initial concentration behavior of impurity ions in the consistency concentration segment one by one. First, taking the raw material addition time period as a reference, it records the correspondence between the initial concentration data of each concentration segment and the starting time of raw material addition. For example, the initial concentration of nickel ions in the consistency concentration segment is 3.0 mg / L at the 10th minute, which is consistent with the starting time of raw material addition. It further analyzes the direction of current change in the electrolytic cell at that moment. For example, if the current is on an upward trend at that moment, it uses the actual electrolytic cell measured current data as a basis, such as 550A at the 10th minute and 550A at the 11th minute. The minute current is 560A, and the current rise rate is 560A-550A=10A / minute, confirming an upward trend in the current. Then, the temperature change data recorded by the temperature sensor is used to determine the temperature change trend in the electrolysis region at the starting moment. For example, if the temperature rises from 28℃ to 29℃ at that moment, the temperature change shows an upward trend. The above parameters are compared one by one. The standard is that the three parameters of the raw material addition start time, the current rise trend, and the temperature rise trend are all met simultaneously. The concentration at the starting point of the diffusion path is determined, and the initial concentration data is used as the concentration value corresponding to the starting point of the diffusion path. For example, if the initial concentration of nickel ions is 3.0mg / L, the diffusion starting point concentration is generated.
[0035] The path correction module includes: The retention determination submodule calls the diffusion initiation concentration, calculates the direction of ion retention time change at each detection point within the boundary region, detects ion retention data at multiple detection points, determines the ion migration delay phenomenon, and generates migration delay parameters by combining the retention time trend. The retention determination submodule calls the diffusion initiation concentration and uses multiple detection points set in the boundary area of the electrolytic cell as the implementation objects. For example, if the detection points are A, B, and C, it records the time data of nickel ion concentration arriving at each detection point from the diffusion initiation. For instance, if the nickel ion arrives at detection point A at minute 8, at B at minute 10, and at C at minute 13, it calculates the retention time of nickel ions between each pair of adjacent detection points. For example, the retention time of nickel ions between A and B is 10 minutes minus 8 minutes, which is 2 minutes; the retention time between B and C is 13 minutes minus 10 minutes, which is 3 minutes. The retention times of each segment are then compared. The direction of change in residence time for each segment is calculated. For example, if the residence time from segment AB to segment BC increases from 2 minutes to 3 minutes, the direction of change is an increasing trend. The trend of change in multiple similar sampling data is statistically analyzed. If the residence time trend is increasing in three consecutive measurements, it is judged as a migration delay phenomenon. The residence data from multiple detection points are combined, and the residence trend of each segment obtained from each sampling is recorded and marked as either an increasing trend or a decreasing trend. The frequency of the trend between each detection point is statistically analyzed. An increasing trend accounting for more than 70% of the total trend frequency is used as the standard for judging migration delay. The proportion of the ion residence time increasing trend is calculated by combining the results of multiple measurements to clarify the degree of migration delay and generate migration delay parameters.
[0036] The distribution comparison submodule compares the distribution differences of loitering behavior in multiple regions based on the migration delay parameter, analyzes the spatial distribution trend of loitering phenomenon, and generates loitering distribution coefficient; The distribution comparison submodule, based on the migration delay parameter, retrieves detection point data from different locations within the electrolytic cell boundary region. For example, regions I, II, and III each contain multiple detection points; detection points A1 and A2 in region I, B1 and B2 in region II, and C1 and C2 in region III. It calculates the average residence time of each detection point within each region. For instance, if detection points A1 in region I have a residence time of 2 minutes and A2 has a residence time of 2.5 minutes, the average residence time for this region is calculated as (2 + 2.5) / 2 = 2.25 minutes. Similarly, it calculates the average residence time for regions II and III. The module then compares the average residence times for each region. For example, if region I has a residence time of 2.25 minutes, region II has a residence time of 3 minutes, and region III has a residence time of 3.5 minutes, the comparison is complete. By direct comparison, the differences in retention behavior among different regions were confirmed, and region III was found to have the longest average retention time. Statistical calculations were performed on the average retention time data of different regions. The difference between the maximum and minimum average retention time between regions was calculated. For example, 3.5 minutes in region III minus 2.25 minutes in region I equals 1.25 minutes. This time difference was used as the basis for assessing the differences in retention distribution among different regions, and was divided by the regional average to determine the retention distribution coefficient, i.e., 1.25 minutes divided by (2.25+3+3.5) / 3, resulting in a retention distribution coefficient of approximately 0.43. The distribution trend of retention phenomena in the electrolytic cell space was confirmed based on the magnitude of the retention distribution coefficient, thus generating the retention distribution coefficient.
[0037] The behavior correction submodule calls the retention distribution coefficient to analyze the retention behavior of the boundary path and the migration trend of the ion continuous sampling segment, corrects the behavior offset parameters of the path segment, adjusts the flow rate rhythm in the current path prediction, and generates the path delay coefficient. The behavior correction submodule calls the retention distribution coefficient to record the migration path data of ions continuously sampled within the electrolyzer boundary area. For example, the starting point of the sampling path is the location corresponding to the diffusion initiation concentration, and the continuous sampling points along the path are detection points X, Y, and Z. It calculates the ion migration velocity between two adjacent sampling points. For instance, the migration velocity of ions from X to Y is the spatial distance (time of peak concentration at position Y minus time of peak concentration at position X) divided by the time difference. If the spatial distance from X to Y is 20 cm and the time difference between the peak concentrations is 2 minutes, then the migration velocity is 20 cm / 2 minutes = 10 cm / minute. Similarly, the migration velocity from Y to Z is calculated. If the velocity decreases segment by segment, such as from X to Y at 10 cm / minute... If the velocity decreases to 7 cm / min in the YZ segment, the migration trend is determined to be deceleration. The influence of the retention distribution coefficient on the ion migration trend in the boundary path is analyzed. This is done by multiplying the retention distribution coefficient by the actual measured migration velocity. For example, if the retention distribution coefficient is 0.43 and the actual migration velocity in the XY segment is 10 cm / min, the corrected velocity is 10 cm / min × (1 - 0.43) = 5.7 cm / min. The original flow rate rhythm in the path prediction is adjusted accordingly. For example, if the original predicted path velocity was 8 cm / min, the adjusted velocity is 5.7 cm / min. Through the above operations, all path segments are corrected one by one, ultimately generating the path hysteresis coefficient.
[0038] The deviation verification module includes: The flow rate deviation submodule calls the path delay coefficient, analyzes the target feed flow rate and the actual execution flow rate in the feed instruction, calculates the degree of difference, determines the deviation range, and generates the flow rate deviation range by combining the periodic flow rate data. The flow rate deviation submodule calls the path delay coefficient, using the target feed flow rate given by the electrolytic cell feeding command as a benchmark. For example, if the target feed flow rate is 20 liters per minute, the actual feed flow rate is measured in real time by a flow sensor. For instance, the measured actual flow rates are 18 liters in the first minute, 17 liters in the second minute, and 19 liters in the third minute. The difference between the target feed flow rate and the actual flow rate is calculated for each minute. For example, the flow rate deviation in the first minute is the target flow rate of 20 liters minus the actual flow rate of 18 liters, which is 2 liters. The deviations at multiple measurement moments are statistically analyzed, and the average flow rate deviation within each cycle is recorded. For example, averaging the deviations of 2 liters, 3 liters, and 1 liter at three measurement moments yields the average deviation within the cycle as (2 + 3). +1) ÷ 3 = 2 liters; Further, the aforementioned path delay coefficient is called, for example, the path delay coefficient is 0.3. By multiplying this coefficient by the average deviation within the cycle, i.e., 2 liters × 0.3 = 0.6 liters, the product value of 0.6 liters is used as the correction amount for the degree of flow velocity deviation. The percentage relationship between the correction amount and the target flow velocity is analyzed. For example, the proportion of 0.6 liters to the target flow velocity of 20 liters is 0.6 ÷ 20 = 3%. Based on this proportion, the degree of flow velocity deviation exceeding 5% is set as a high deviation range, and less than or equal to 5% is set as a normal deviation range. The 3% calculated in this cycle is included in the normal deviation range. The deviation range data of multiple cycles are determined by this method. The statistical data of the deviation range of each cycle are summarized to generate the flow velocity deviation range.
[0039] The viscosity analysis submodule, based on the flow rate deviation range, calls upon the current flow characteristics and standard flow state of the feeding medium to analyze the impact of viscosity changes on the flow rate during the execution phase and generates a viscosity influence coefficient. The viscosity analysis submodule, based on the flow rate deviation range, retrieves the flow characteristic data of the feeding medium in its current state. For example, if the medium is electrolyte, and the current viscosity is measured to be 5.5 mPa·s using a viscometer, it also retrieves the viscosity value of the electrolyte under standard flow conditions set in the standard process, for example, a standard viscosity value set to 5.0 mPa·s. The module records the viscosity values of the current state and the standard state respectively. It calculates the difference between the current viscosity and the standard viscosity, specifically by subtracting the standard viscosity value from the current viscosity value. For example, the calculation result is 5.5 mPa·s - 5.0 mPa·s = 0.5 mPa·s. The module then analyzes the impact of this viscosity difference on the feeding flow rate during the actual execution phase, retrieving data from multiple cycles. The actual flow rate of the material is measured, and the deviation between the actual flow rate and the target flow rate in each cycle is calculated. For example, in the aforementioned actual flow rate measurement data, the deviation in the first cycle is 2 liters. The deviation data for each cycle are recorded as 2 liters, 3 liters, and 1 liter, respectively. The viscosity difference of 0.5 mPa·s is correlated with the actual flow rate deviation data. Specifically, the average value of the flow rate deviation in multiple cycles is calculated. For example, the average value is (2+3+1)÷3=2 liters. The viscosity difference is divided by the average flow rate deviation, i.e., 0.5 mPa·s÷2 liters=0.25 mPa·s / liter. This value is defined as the viscosity influence coefficient. This coefficient is used to quantify the degree of influence of viscosity change on the actual flow rate in the feeding execution stage, and the viscosity influence coefficient is generated.
[0040] The signal adjustment submodule calls the viscosity influence coefficient to adjust the flow rate control parameter range of the control signal, establishes the feedback relationship between viscosity and execution response offset, and generates the feeding compensation configuration. The signal adjustment submodule calls the viscosity influence coefficient, using the original feed flow rate control parameter range in the control signal as the adjustment basis. For example, if the original flow rate control parameter range was set to 18 to 22 liters per minute, the viscosity influence coefficient of 0.25 mPa·s / L is used to calculate the flow rate parameter adjustment corresponding to the viscosity change. Specifically, this is the product of the viscosity influence coefficient and the viscosity change, i.e., 0.25 mPa·s / L × 0.5 mPa·s = 0.125 liters. This adjustment amount is used to adjust the upper and lower limits of the original flow rate control parameter range separately. For example, the upper limit flow rate of 22 liters minus the adjustment amount of 0.125 liters results in an adjusted flow rate of 21.875 liters, and the lower limit flow rate of 18 liters minus the adjustment amount of 0.125 liters results in an adjusted flow rate of 21.875 liters. The flow rate was then adjusted to 17.875 liters, completing the adjustment of the flow rate control parameter range. Further, based on the adjusted flow rate control parameter range, the actual measured viscosity and flow rate data were retrieved, and the data correlation between the measured viscosity change and the actual executed flow rate deviation was compared one by one. For example, a viscosity deviation of 0.5 mPa·s corresponds to an actual flow rate deviation of 2 liters. This establishes a feedback data relationship between viscosity and the executed response deviation. Specifically, a viscosity change of 0.1 mPa·s corresponds to an actual flow rate deviation of 0.4 liters. Multiple similar viscosity-flow rate data records were recorded and summarized to form a corresponding relationship dataset. Finally, the adjusted flow rate control parameter range and the corresponding relationship dataset were used to generate the feeding compensation configuration.
