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.

[0130] The period analysis submodule calls impurity response information, which is the action strength data of the influence of different impurity ions on the lattice established in the foregoing steps, selects the concentrations of multiple impurity ions such as nickel ions and copper ions as the analysis objects, and collects the concentration data of nickel ions and copper ions in the residual liquid at the end of each electrolysis period, for example, the nickel ion concentration is 3.8 mg / L and the copper ion concentration is 2.4 mg / L at the end of a certain period, and the same ion concentration values of the previous period are recorded, which are nickel ion 3.2 mg / L and copper ion 1.9 mg / L, respectively. The change trend of the concentration of each impurity ion is calculated one by one, specifically, the current period concentration is subtracted from the previous period concentration, such as nickel ion 3.8 mg / L-3.2 mg / L = 0.6 mg / L and copper ion 2.4 mg / L-1.9 mg / L = 0.5 mg / L. The raw material feeding control system is called to obtain the feeding time of the raw material, and the time position of the start of the raw material feeding in the electrolytic cell is recorded, for example, the start time of the raw material feeding in this period is the 10th minute and the end time is the 15th minute. The time sequence range of the period span is determined in this way, the concentration fluctuation amplitude of each ion in the period is counted one by one according to the impurity concentration data of two consecutive periods, specifically, the difference between the maximum and minimum values measured in each period is calculated, such as nickel ion concentration maximum 4.0 mg / L and minimum 3.0 mg / L, fluctuation amplitude 4.0 mg / L-3.0 mg / L = 1.0 mg / L. The fluctuation amplitude of copper ions is calculated as 0.8 mg / L. The fluctuation amplitude of each ion is recorded, and the concentration fluctuation interval of each ion in the period is determined according to the data record of the concentration fluctuation amplitude in multiple periods, for example, the nickel ion fluctuation interval is 3.0 mg / L-4.0 mg / L and the copper ion fluctuation interval is 1.9 mg / L-2.7 mg / L. The period concentration interval is generated.
[0131] The interval screening submodule screens the concentration segments with consistent fluctuation direction according to the period concentration interval, identifies the concentration change segments consistent with the period fluctuation in combination with the impurity concentration change trend parameter, extracts the fluctuation consistency marker, and generates the consistent concentration segment.
[0132] The interval screening submodule calls the periodic concentration interval data of impurity ions such as nickel ions and copper ions based on the recorded concentration data of multiple periods according to the periodic concentration interval, and determines the concentration fluctuation direction of the impurity ions period by period. Taking the time sequence of the maximum and minimum concentration values as the basis, for example, the maximum concentration value of nickel ions in period 1 appears at the end of the period, and the minimum concentration value appears at the beginning of the period. Therefore, it is determined that the fluctuation trend of nickel ions in the period is an upward trend. The similar judgment of fluctuation trend is performed for each ion in multiple periods. By comparing the fluctuation trend of ion concentration whether it remains consistent in multiple consecutive periods, the complete consistency of impurity ion fluctuation direction in three consecutive periods is taken as the standard of consistent fluctuation direction. For example, nickel ions in consecutive periods 1, 2 and 3 all show an upward trend in concentration, and copper ions in periods 1 and 2 show an upward trend but in period 3 show a downward trend. Therefore, nickel ions meet the consistent fluctuation direction standard, and copper ions do not. The concentration fluctuation data segments of all impurities that meet the consistent fluctuation direction standard are screened, and the concentration values in each segment are marked, such as the concentration segments of nickel ions in periods 1 to 3 are marked as consistent concentration segments. The marked segments are associated with the impurity concentration change trend parameters and recorded to generate consistent concentration segments.
[0133] The path determination submodule calls the consistent concentration segment, combines the raw material adding period, the current change direction and the temperature change region, determines the starting concentration behavior of the impurity in the concentration change segment, analyzes the matching and trend of each parameter, establishes the concentration value corresponding to the starting point of the diffusion path, and generates the starting concentration of the diffusion starting point.
[0134] The path determination sub-module calls the consistency concentration section, and compares the initial concentration behavior of impurity ions in the consistency concentration section one by one based on the recorded raw material adding period, current change direction and temperature change region. First, the raw material adding period is taken as a reference, and the corresponding relationship between the concentration data at the beginning of each concentration section and the starting time of raw material addition is recorded. For example, the time when the initial concentration of nickel ions in the consistency concentration section is 3.0 mg / L is the 10th minute, which is consistent with the starting time of raw material addition. Further analysis of the current change direction corresponding to this time is performed, for example, the current is in an upward trend at this time. Based on the actual electrolytic tank measured current data, for example, the current is 550 A at the 10th minute and 560 A at the 11th minute, and the current rising rate is 560 A-550 A=10 A / minute, confirming that the current trend is rising. Then, the temperature change data recorded by the temperature sensor is called to determine the temperature change trend in the electrolysis region at this starting time, for example, the temperature rises from 28°C to 29°C at this time, and the temperature change is in an upward trend. The above parameters are compared respectively, and the starting concentration data is called as the concentration value corresponding to the diffusion path starting point, for example, the initial concentration of nickel ions is 3.0 mg / L, and the diffusion starting point concentration is generated.
[0135] The path correction module includes:
[0136] The retention judgment sub-module calls the diffusion starting point concentration, calculates the ion retention time change direction of each detection point in the boundary region, detects the retention data of ions at multiple detection points, judges the migration delay phenomenon of ions, and generates a migration delay parameter in combination with the retention time trend.
[0137] The residence judgment submodule calls the diffusion starting point concentration, and sets multiple detection points at the boundary region of the electrolytic cell as the implementation object, such as detection points A, B, and C. The time data of nickel ion concentration from the diffusion starting point to each detection point is recorded, for example, the time of nickel ion from the diffusion starting point to detection point A is 8 minutes, to B is 10 minutes, and to C is 13 minutes. The residence time of nickel ion between each two adjacent detection points is calculated, such as the residence time of nickel ion between A and B is 10 minutes minus 8 minutes, that is, 2 minutes; the residence time between B and C is 13 minutes minus 10 minutes, that is, 3 minutes. The residence times of each section are compared one by one, and the change direction of each section of residence time is calculated, such as the residence time from A-B section to B-C section increases from 2 minutes to 3 minutes, that is, the change direction is the lengthening trend. The change trend of multiple similar sampling data is counted, and if the residence time trend is lengthened for 3 consecutive measurements, it is judged as the migration delay phenomenon. The residence data of multiple detection points are integrated, the residence trend of each sampling is recorded, and the lengthening trend or shortening trend is marked respectively. The frequency of the trend between each detection point is counted, and the lengthening trend accounts for more than 70% of the total trend number as the standard for judging the migration delay. The proportion of the lengthening trend of ion residence time is calculated combined with multiple measurement results, the degree of migration delay is determined, and the migration delay parameter is generated.
[0138] The distribution comparison submodule compares the distribution difference of the residence behavior of multiple regions according to the migration delay parameter, analyzes the distribution trend of the residence phenomenon in space, and generates a residence distribution coefficient.
[0139] The distribution comparison submodule calls the detection point data at different positions in the boundary region of the electrolytic cell according to the migration delay parameter, for example, regions I, II, and III each contain multiple detection points, such as detection points A1 and A2 in region I, B1 and B2 in region II, and C1 and C2 in region III; the average residence time of the detection points in each region is calculated, for example, the average residence time of region I is (2+2.5) / 2=2.25 minutes, and the average residence time of region II and III is calculated in the same way; the average residence time of each region is compared one by one, for example, the average residence time of region I is 2.25 minutes, the average residence time of region II is 3 minutes, and the average residence time of region III is 3.5 minutes; by direct comparison, the difference in residence behavior of each region is confirmed, and it is determined that the average residence time of region III is the longest; the average residence time data of different regions is statistically calculated, and the difference between the maximum average residence time and the minimum average residence time between regions is obtained, for example, 3.5 minutes of region III minus 2.25 minutes of region I is 1.25 minutes; the time difference is taken as the basis for evaluating the difference in residence distribution of different regions, and divided by the average value of the region to determine the residence distribution coefficient, that is, 1.25 minutes divided by (2.25+3+3.5) / 3, and the residence distribution coefficient is calculated to be about 0.43; the residence distribution coefficient value is used to confirm the distribution trend of the residence phenomenon in the electrolytic cell space, and the residence distribution coefficient is generated.
[0140] The behavior correction submodule calls the residence distribution coefficient, analyzes the residence behavior of the boundary path and the migration trend of the ion continuous sampling section, corrects the behavior offset parameter of the path line segment, adjusts the flow rate rhythm in the current path prediction, and generates the path delay coefficient;
[0141] The behavior correction sub-module calls the retention distribution coefficient, respectively records the ion continuous sampling migration path data in the electrolytic cell boundary area, such as the sampling path starting point is the position corresponding to the diffusion starting point concentration, the path continuous sampling points are detection points X, Y and Z; the ion migration speed between adjacent two sampling points is calculated, for example, the ion migration speed from X to Y is (the time difference of the position Y concentration peak value appearance time minus the position X concentration peak value appearance time) corresponding to the spatial distance divided by the time difference; such as the spatial distance from X to Y is 20 cm, the concentration peak time difference is 2 minutes, then the migration speed is 20 cm / 2 minutes=10 cm / minute; similarly, the migration speed from Y to Z is calculated, if the speed decreases gradually, such as from X-Y 10 cm / minute to Y-Z 7 cm / minute, then it is judged that the migration trend is deceleration; the influence of the retention distribution coefficient of the retention behavior in the boundary path on the ion migration trend in the path is analyzed, the retention distribution coefficient is multiplied by the actual measured migration speed, such as the retention distribution coefficient is 0.43, the actual migration speed of X-Y section is 10 cm / minute, then the corrected speed is 10 cm / minute x (1-0.43)=5.7 cm / minute; the original flow rate rhythm in the path prediction is adjusted correspondingly, such as the original set prediction path speed is 8 cm / minute, the adjusted speed is 5.7 cm / minute; all path segments are corrected one by one through the above operation, and finally the path retention coefficient is generated.
[0142] The deviation check module includes:
[0143] The flow rate deviation sub-module calls the path retention coefficient, analyzes the target feeding flow rate and the actual execution flow rate in the feeding instruction, calculates the difference degree, judges the deviation interval, combines the periodic flow rate data, and generates the flow rate deviation interval;
[0144] The flow rate deviation module calls the path delay coefficient based on the target feeding flow rate given by the electrolytic cell feeding instruction. For example, if the target feeding flow rate is 20 liters per minute, the actual feeding flow rate is measured in real time by a flow sensor, for example, the measured actual flow rates are 18 liters per minute in the first minute, 17 liters per minute in the second minute, and 19 liters per minute in the third minute. The difference between the target feeding flow rate and the actual flow rate is calculated one by one, for example, the flow rate deviation in the first minute is 20 liters (target flow rate) minus 18 liters (actual flow rate), which is 2 liters. The deviations at multiple measurement times are counted, and the average flow rate deviation in each period is recorded, for example, the average deviation in the period is calculated by averaging the deviations of 2 liters, 3 liters, and 1 liter at the three measurement times, which is (2+3+1) ÷ 3 = 2 liters. Further, the aforementioned path delay coefficient is called, for example, the path delay coefficient is 0.3, and the product of the coefficient and the average deviation in the period is calculated, which is 2 liters × 0.3 = 0.6 liters. The product value 0.6 liters is used as the correction amount of the flow rate deviation degree, and the percentage relationship between the correction amount and the target flow rate is analyzed, for example, the proportion of 0.6 liters to the target flow rate of 20 liters is 0.6 ÷ 20 = 3%. According to this proportion, it is determined that the flow rate deviation degree exceeding 5% is in the high deviation interval, and the flow rate deviation degree less than or equal to 5% is in the normal deviation interval. The 3% calculated in the current period is classified into the normal deviation interval, and the deviation interval data of multiple periods is determined by this method. The statistical data of the deviation interval of each period is summarized to generate the flow rate deviation interval.
[0145] The viscosity analysis submodule analyzes the influence of viscosity change on the flow rate in the execution stage according to the flow rate deviation interval, calls the current flow characteristics and standard flow state of the feeding medium, and generates a viscosity influence coefficient.
[0146] The viscosity analysis submodule calls the flow characteristic data of the current state of the feeding medium according to the flow rate deviation interval, such as the electrolyte, the real-time viscosity is measured as 5.5 mPa·s under the current state using the viscometer, and the viscosity value of the standard flow state of the electrolyte set by the standard process is called, for example, the standard viscosity value is set as 5.0 mPa·s, and the viscosity values of the current state and the standard state are recorded respectively; the difference between the viscosity of the current state and the standard viscosity is calculated, 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 influence direction of the viscosity difference on the feeding flow rate in the actual execution stage is analyzed, the measurement data of the actual feeding flow rate in multiple cycles is called, and the deviation amount of the actual flow rate and the target flow rate in each cycle is calculated, such as the first cycle deviation in the foregoing actual flow rate measurement data is 2 liters, the cycle deviation data is recorded as 2 liters, 3 liters and 1 liter respectively, the viscosity difference 0.5 mPa·s is associated with the actual flow rate deviation data, specifically by calculating the average value of the flow rate deviation amount in multiple cycles, for example, the average value is (2+3+1)÷3=2 liters, the viscosity difference is divided by the average flow rate deviation amount, that is, 0.5 mPa·s÷2 liters=0.25 mPa·s / liter, and the value is defined as the viscosity influence coefficient, which quantifies the influence degree of viscosity change on the actual flow rate in the feeding execution stage, and generates the viscosity influence coefficient.
[0147] 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 the viscosity and the execution response deviation, and generates the feeding compensation configuration;
[0148] 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.
