[0059] See attached Figure 2 , which shows a flow chart of a monitoring and analysis method for preparing a marine peptide provided by an embodiment of the present invention, the method comprising the following steps:

[0060] S1. Collect the original production parameter data in the production process, perform intelligent processing on the original production parameter data, and obtain the production parameter data after intelligent processing; perform intelligent analysis on the production parameter data after intelligent processing to obtain the status analysis results;

[0061] In the marine peptide preparation equipment, the original production parameter data in the production process is collected in real time based on a variety of sensors deployed by professional technicians. The sensors include temperature sensors, pH sensors, pressure sensors, flow meters, spectrometers, redox potential sensors, dissolved oxygen sensors, etc.;

[0062] The original production parameter data is intelligently processed. The specific process is as follows:

[0063] The original production parameter data is subjected to Gaussian filtering to remove random noise in the original production parameter data, and the denoised production parameter data is obtained. Then, the denoised production parameter data is subjected to an outlier detection algorithm with an adaptive threshold to remove extreme data that may appear in the production process, thereby realizing outlier detection and removal. The adaptive threshold is defined as follows:

[0064]

[0065] in, Is an adaptive threshold used to determine the time Whether the production parameter data after denoising is an abnormal value, changes over time, and is dynamically adjusted; It's time The mean of the denoised production parameter data at the moment reflects the central trend of the denoised production parameter data at the moment; is the weight coefficient of the standard deviation, which controls the influence of the standard deviation on the threshold; It's time The standard deviation of the denoised production parameter data at the time instant indicates the degree of fluctuation of the denoised production parameter data. The larger the standard deviation, the more drastic the fluctuation of the production parameter data. is the skewness adjustment coefficient, which is used to control the effect of skewness on the threshold correction and increase the sensitivity of asymmetric data distribution; It's time The skewness coefficient at time is used to describe the symmetry of the data distribution. , It is the expected value operator, which is used to calculate the third-order moment of the data and reflect the distribution form of the data; It's time The denoised production parameter data at each moment; is the time decay coefficient, which changes with time As increases, the adjustment amount for anomaly detection is gradually reduced.

[0066] When the difference between the denoised production parameter data and the mean of the denoised production parameter data is greater than the adaptive threshold, the denoised production parameter data is an abnormal value and is removed.

[0067] The production parameter data that has been detected and eliminated for outliers are standardized to obtain production parameter data of the same magnitude, thereby realizing intelligent processing of the production parameter data and obtaining production parameter data after intelligent processing.

[0068] Furthermore, the dynamic hierarchical feature mapping and time domain offset transformation analysis method are combined with the production characteristics after historical time domain offset transformation to perform intelligent analysis on the production parameter data after intelligent processing to obtain the state analysis results. The specific implementation process is as follows:

[0069] The dynamic hierarchical feature mapping and time domain offset transformation analysis method can capture subtle changes in production parameter data after intelligent processing in a multi-dimensional dynamic environment through dynamic hierarchical feature mapping, time domain offset transformation and feature interaction analysis, form an accurate assessment of the current production status, and provide a data basis for adaptive adjustment suggestions.

[0070] The production parameter data after intelligent processing is processed by dynamic hierarchical feature mapping. The purpose of dynamic hierarchical feature mapping is to map the matrix , projecting different production parameter data into independent feature spaces. Each feature space independently reflects the internal characteristics of a type of production parameter, which helps to further separate the impact of various production parameters on the production process. The mapping formula is defined as:

[0071]

[0072] in, Representative The mapping result of the feature layer reflects the moment Production features after dynamic hierarchical feature mapping; It is a dynamic mapping matrix that converts the current intelligently processed production parameter data set Mapping to a specific feature space; It's time The intelligently processed production parameter data set contains production parameter data in multiple dimensions;

[0074] is the dynamic mapping matrix The Line The elements of the column represent the time No. How to map the production parameter data to the feature dimensions, and transform the intelligently processed production parameter data into data in the feature space through a mapping matrix for subsequent analysis and optimization; It is The standard deviation of the intelligently processed production parameter data is used to standardize the fluctuation of the production parameter data; It is The production parameters after intelligent processing are The value of the moment; It is feature dimension in time The expected value (mean) at the moment; is the periodic adjustment coefficient, used to control the The time periodic fluctuation of production parameter data after intelligent processing;

[0075] In order to further capture the time-varying characteristics of the data, the time domain offset transformation is introduced. By performing the time domain offset transformation operation on the mapped production features, a new feature space is constructed. The time domain offset transformation formula is as follows:

[0076]

[0077] in, Indicates The production characteristics of each feature layer after time domain migration transformation; is the time shift coefficient, which controls the delay effect of the time domain shift transform; It is The rate of change of production characteristics of a feature layer over time.

[0078] Furthermore, after dynamic hierarchical feature mapping and time domain shift transformation, feature interaction analysis is performed on data from different feature layers to evaluate the intrinsic connection between data in each dimension. By introducing feature cross terms, the feature interaction strength between different feature layers is calculated. The feature interaction strength is calculated using the following formula:

[0079]

[0080] in, It is Layer and The feature interaction strength between the feature layers indicates the feature interaction strength between the data of two feature layers. ; is the characteristic cross term; is a small positive number used to prevent the denominator from being zero; It is The production features of each feature layer after time domain migration transformation.

[0081] After obtaining the feature interaction strength between feature layers, in order to give priority to the feature layers that have a greater impact on production and ensure that important production parameters can be focused on during analysis, weights are assigned to different feature layers according to the feature interaction strength. The allocation formula is as follows:

[0082]

[0083] in, Indicates the total number of feature layers;

[0084] Furthermore, the weighted feature results of different feature layers are comprehensively evaluated to calculate the production state deviation. The production state deviation is used to evaluate the difference between the current production state and the historical best production state. The formula is as follows:

[0085]

[0086] in, It is the current moment The production state deviation indicates the degree of deviation between the current production state and the historical optimal production state. change; It is the current moment No. Layer characteristic layer's production characteristics after historical best time domain migration transformation; is the weighted feature result;

[0087] After calculating the production state deviation, the production conditions are adjusted according to the production state deviation. The state correction model is introduced to adjust the production conditions in real time, and multi-dimensional nonlinear adjustment items are also introduced to make the state correction model more sensitive to abnormal situations. The mathematical formula of the state correction model is as follows:

[0088]

[0089] in, It is the correction value of the production condition, indicating how to adjust the first Data on production parameters over time Change, the characteristics of each layer correspond to a production parameter; It is a multidimensional nonlinear adjustment term; It is the correction sensitivity coefficient that controls the response intensity to production status deviations.

[0090] Finally, the correction values ​​of all production conditions are combined to form the state analysis result , including all Provide data basis for adaptive assessment.

[0091] S2. Perform adaptive evaluation on the state analysis results through the multi-dimensional dynamic state adaptive evaluation algorithm of marine peptide preparation to generate state evaluation results; generate adjustment suggestions based on the state evaluation results; convert the adjustment suggestions into control instructions to automatically regulate the marine peptide preparation equipment.

[0092] The state analysis results are adaptively evaluated using the multi-dimensional dynamic state adaptive evaluation algorithm for marine peptide preparation to evaluate whether there are abnormalities in the production process and obtain the state evaluation results; the specific implementation process is as follows:

[0093] Firstly, the state analysis results are dynamically nonlinearly combined by introducing time transformation and dynamic weight to capture the dynamic performance of the state analysis results in different time periods and under different production conditions. The specific formula is:

[0094]

[0095] in, It is the state analysis result after dynamic nonlinear combination, and the correction value of each production condition is The complex nonlinear behaviors of the production process are combined together and the cumulative effect over time is added to describe the dynamic changes of the entire production process. is the nonlinear regulation coefficient, which is used to control the intensity of the sinusoidal regulation function; It is a nonlinear trigonometric function, reflecting the correction value of production conditions Dynamic behavior of is the smoothing factor, which is used to control the sensitivity of this term to small deviations; is the amplification factor of the correction rate of change of production conditions; is the historical cumulative weight factor, which is used to control the contribution of the correction value of production conditions in the historical cumulative effect; is the corrected rate of change of production conditions.

[0096] Furthermore, the state analysis results after dynamic nonlinear combination are adaptively evaluated to detect whether there are abnormalities in the production process and to evaluate whether the current production state needs to be adjusted. State analysis results after combining with historical best dynamic nonlinearity By comparison, the degree of deviation of the current production status can be evaluated. The adaptive evaluation formula is:

[0097]

[0098] in, It is the production state deviation evaluation value, which is used to measure the deviation degree of the state analysis result after the current dynamic nonlinear combination relative to the state analysis result after the historical best dynamic nonlinear combination, and integrates the cumulative effect over time and the nonlinear behavior of the current production state; is an integral variable, representing the time point between the start of production and the current moment; is the adaptive adjustment coefficient, which controls the nonlinear adjustment sensitivity to the current production status and is used to balance the contribution of the sinusoidal term in the overall production status evaluation; It is the nonlinear adjustment coefficient, which controls the response amplitude of the sine function to the current production status and is used to balance the impact of nonlinear adjustment on production status evaluation.

[0099] Finally, the production status deviation assessment value is compared with the threshold value preset according to the expert experience method. If the production status deviation assessment value exceeds the threshold value, the monitoring and analysis system for the preparation of marine peptides determines that there is an abnormality in the current production process. According to the difference between the production status deviation assessment value and the preset threshold value, a status assessment result is generated. The status assessment results are divided into slight deviations, moderate deviations and severe deviations. Adjustment suggestions are generated based on the status assessment results. For example, for slight deviations, it is recommended to lower or raise the temperature by 0.1-0.5 degrees through fine adjustment to keep it within the optimal range. It is recommended to use trace amounts of acid and alkali solutions for slow adjustment to gradually adjust the pH value to the optimal range, and the adjustment range should not exceed 0.1. It is recommended to moderately adjust the pump speed or valve opening to adjust the flow rate to the predetermined optimal value. For moderate deviations, it is recommended to quickly adjust the temperature to the set target range, with an adjustment range of about 0.5-2 degrees, which varies appropriately according to the current environment and process requirements. It is recommended to quickly add acid and alkali solutions to quickly restore the pH value to a reasonable range, but it is necessary to avoid adding too much solution at one time to prevent over-adjustment and keep it within the range of 0.1-0.3. It is recommended to adjust the pump speed or increase or decrease the valve opening according to production needs, and the adjustment range should be within the range of 10%-20% to ensure that the material flow rate adapts to the current production status. For severe deviations, it is recommended to immediately force the temperature to return to a safe range. At this time, it is recommended to suspend some production operations and continue production after the temperature returns to normal; it is recommended to take emergency measures immediately to quickly neutralize excess acid or alkali, and accelerate uniform mixing through stirring to avoid excessive concentration in local areas.

[0100] After the adjustment suggestions are generated, the above suggestions are converted into specific control instructions to achieve automatic regulation of the marine peptide preparation equipment.

[0101] The production parameter data after intelligent processing in the production process, the production characteristics after time domain offset transformation, the state analysis results, the state assessment results, the state analysis results after dynamic nonlinear combination, and the adjustment suggestions are stored and used as historical data.
