Description

Technical Field

[0001] This invention relates to the technical field of tortoise shell glue bead production control, and in particular to a method for controlling the parameters of the entire tortoise shell glue bead process based on data algorithms. Background Technology

[0002] Tortoise shell glue, a precious traditional Chinese medicine, possesses significant medicinal effects such as nourishing yin and suppressing yang, tonifying the kidneys and strengthening bones, and is widely used in clinical and health care fields. In both traditional and modern processing of tortoise shell glue, the glue blocks are typically cut into cubes and then stir-fried at high temperatures with excipients such as clam powder and talc powder. This causes the glue to expand and form brittle tortoise shell glue beads, facilitating subsequent pulverization, decoction, and the dissolution of active ingredients. With the advancement of modernization in traditional Chinese medicine production, equipment such as electromagnetic stir-frying machines and automated granule packaging machines have been widely used in tortoise shell glue bead production lines. However, in actual large-scale industrial production, existing processing control methods and production line coordination mechanisms still face many technical bottlenecks that urgently need to be addressed.

[0003] First, existing technologies lack scientific quantitative assessment and adaptive adjustment mechanisms when dealing with batch variations in raw materials. The initial moisture content and particle size distribution of tortoise shell gelatin cubes are key factors affecting the frying quality. Fluctuations in moisture content directly affect the uniformity of heat transfer in the pan and the rate of thermal expansion of the gelatin cubes; while uneven particle size easily leads to the phenomenon of "small particles burning and large particles undercooked" during frying, severely restricting the improvement of the qualified bead formation rate. Currently, most manufacturers still rely on fixed process parameters or manual experience for production, failing to establish comprehensive evaluation indicators based on the multidimensional characteristics of raw materials (such as moisture content and particle size variation coefficient). This results in the selection and dosage of auxiliary materials (such as clam powder or talc) often being fixed or based solely on subjective judgment, failing to achieve precise matching for the characteristics of the current batch of materials, thus causing fluctuations in frying quality.

[0004] Secondly, existing roasting equipment lacks data-driven dynamic optimization capabilities in parameter settings. In the control of electromagnetic roasting machines, roasting temperature and stirring frequency are the core control variables determining the quality of the beads. Traditional control systems typically employ open-loop control or simple fixed threshold settings, failing to effectively combine the adaptability characteristics of the upstream materials with process data from historical high-quality batches. Due to the lack of intelligent optimization algorithms for offline calibration and online interpolation, existing methods cannot automatically recommend and distribute the optimal combination of temperature and stirring frequency based on the actual conditions of the current batch of materials. This leads to a disconnect between equipment operating parameters and actual material requirements, increasing energy consumption and making it difficult to guarantee the uniformity of each batch of tortoise shell glue beads.

[0005] Furthermore, existing production lines suffer from severe "information silos" between the roasting and packaging processes, lacking a closed-loop, integrated control system for the entire process. The discharge rate after roasting is often a non-stationary process that fluctuates over time, while existing granule packaging machines (such as the DXDK granule packaging machine) typically operate with fixed target weighing settings and gate opening / closing rhythms. Because the discharge rhythm of the roasting process cannot be predicted in advance, the packaging equipment cannot preset parameters before the material actually arrives. This mismatch between the upstream and downstream processes easily leads to large accumulations and blockages of material at the packaging station, or equipment idling and waiting, severely reducing the overall operating efficiency of the production line.

[0006] Finally, regarding dynamic control strategies, existing technologies struggle to handle complex disturbances during the material discharge process. Although some advanced production lines have introduced sensors for monitoring, these are mostly limited to single feedback control, exhibiting significant lag. When the discharge rate fluctuates drastically, simple feedback adjustment often leads to frequent gate actuation of the packaging machine or increased weighing errors. Existing methods generally lack adaptive error-driven control strategies that integrate feedforward prediction with real-time feedback adjustment, making it difficult to maintain a high-precision dynamic match between the packaging process's processing rate and the front-end roasting discharge rate.

[0007] In summary, to address the industry pain points such as the large differences in raw material characteristics, low accuracy in matching auxiliary materials and frying parameters, and poor coordination between front-end and back-end processes in the production of tortoise shell glue beads, there is an urgent need for a data algorithm-based full-process parameter control method for tortoise shell glue beads. This method would enable intelligent linkage control of the entire process from material preparation and frying to packaging, thereby effectively improving the yield of qualified beads and enhancing the automated production efficiency of the entire line. Summary of the Invention

[0008] In view of this, the present invention provides a data algorithm-based method for full-process parameter control of tortoise shell glue beads. The purpose is to achieve precise adaptive matching of auxiliary material selection and frying parameters through in-depth analysis and quantitative evaluation of material characteristics, and to establish a linkage control mechanism based on feedforward prediction and feedback adaptive fusion, thereby eliminating the cycle time barrier between the front and back processes and comprehensively improving the qualified bead formation rate and the overall automated production efficiency of tortoise shell glue beads.

[0009] To achieve the above objectives, this invention provides a method for controlling the entire process parameters of tortoise shell glue beads based on data algorithms, comprising the following steps: B1: The initial moisture content and particle size distribution of the tortoise shell glue cubes in the current batch are detected. Based on the influence of the initial moisture content of the wet base on the heat transfer uniformity of the auxiliary materials in the pot and the influence of the non-uniformity of the particle size on the qualified bead formation rate, the two types of characteristics are assigned corresponding weights and weighted fusion is performed to generate the stir-frying compatibility index of the current batch. B2: Taking the stir-fry compatibility index as input, the auxiliary material type is automatically selected based on the partition threshold rules determined by the historical batch auxiliary material selection rules, and the precise auxiliary material dosage is determined based on the piecewise linear interpolation lookup table of the auxiliary material dosage calibrated offline for each auxiliary material type. The auxiliary material type selection result and the precise auxiliary material dosage are output. B3: Using the excipient type selection result and the stir-frying compatibility index as a joint index, query the offline calibrated stir-frying parameter recommendation lookup table, output the quality verification qualified temperature setting value and stirring drive frequency setting value of the current batch through piecewise linear interpolation, and send the parameter combination to the electromagnetic stir-frying machine control system for execution; B4: Use a feedforward prediction model of discharge rhythm trained based on historical batch roasting cycle data to estimate the time sequence distribution of discharge rate in the current batch roasting process in advance, and provide parameter preset basis for packaging equipment before the material actually arrives at the packaging station. B5: Using the time-series prediction value of the discharge rate as the feedforward benchmark, the actual discharge rate measurement value collected by the packaging station sensor is synchronously integrated. Through the feedforward-feedback fusion error-driven adaptive control strategy, the target weighing set value and the opening and closing rhythm parameter vector of the DXDK granule packaging machine are continuously updated. This ensures that the processing rate of the packaging process and the discharge rate of the front-end roasting process are dynamically matched, realizing a linkage control closed loop from material preparation parameters, roasting parameters to packaging parameters with the discharge rate matching as the goal.

[0010] As a further improvement of the present invention: Optionally, step B1 further includes: The current batch of tortoise shell glue cubes was sampled and tested using a halogen moisture analyzer.

Two independent univariate standardized regression analyses were conducted on historical batch data. The initial moisture content and particle size variation coefficient of each historical batch (standardized by z-score) were used as independent variables, and the qualified bead formation rate of the corresponding batch was used as the dependent variable.

Then proceed with the next steps; Separate piecewise linear interpolation lookup tables were created for the dosage of clam powder and talcum powder; each lookup table was based on a stir-fry compatibility index.

Strictly ascending in order of increasing value; if duplicate values ​​appear in the initially determined calibration and cooking compatibility index, the average value of the actual auxiliary material usage of qualified batches within the corresponding interval will be calculated and replaced by a single calibration index point.

[0012] Optionally, step B3 further includes: Separate lookup tables for recommended stir-frying parameters were created for clam powder and talcum powder; each lookup table is based on a stir-frying suitability index. As an index variable, store The calibration index point, the first One calibration index point, Includes calibrated stir-frying compatibility index Recommended temperature calibration values Recommended calibration value for stirring drive frequency Recommended calibration value for temperature at the calibration index point.

The values ​​are arranged in a strictly ascending order. If duplicate values ​​appear in the initially determined calibration roasting compatibility index, the average of the actual temperature and frequency records of qualified batches within the corresponding interval is calculated and replaced by a single calibration index point.

The electromagnetic roasting machine control system then adjusts the heating power and stirring drive frequency according to the roasting parameter package. The control value for the stirring speed is sent to the frequency converter drive unit of the electromagnetic stir-frying machine.

[0013] Optionally, step B4 further includes: Construct a feedforward prediction model for the discharge rhythm, wherein the feedforward prediction model for the discharge rhythm uses a temperature setpoint.

With particle size variation coefficient Stir-frying suitability index and the actual amount of material fed into the current batch. The concatenated 8-dimensional feature vector serves as input. A one-dimensional convolutional layer extracts local correlation features between the components of the input parameters. A max-pooling layer compresses these local correlation features.

The time step, the first The feedforward prediction of the discharge rate at each time step is denoted as . , ; The time-series predicted value sequence , ,..., When the current batch of roasting process starts, the feedforward prediction calculation is performed and a complete time-series prediction value sequence is generated. Before the material arrives at the packaging station, the prediction value sequence is output to the DXDK granule packaging machine control unit. The control unit then uses the time-series prediction value sequence to pre-set the initial parameters of the target weighing set value and the opening and closing rhythm of the feeding gate.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: This invention innovatively constructs a frying adaptation index generation mechanism based on dynamic weighting of multi-dimensional material characteristics by deeply mining historical batch data. Unlike conventional fixed-weight evaluation or simple multivariate linear superposition, this invention utilizes univariate standardized regression analysis to extract the absolute sensitivity of the initial moisture content and particle size variation coefficient of the wet basis. Based on this, feature weights are adaptively allocated, and range normalization and truncation are performed. This improved algorithm accurately quantifies the comprehensive impact of the current batch of materials on heat transfer uniformity and bead formation rate, overcoming evaluation biases caused by extreme material characteristics. It provides a highly customized quantitative benchmark for subsequent automatic selection and dosage calculation of auxiliary materials. Furthermore, combined with a three-zone decision rule with an anomaly alarm mechanism and a piecewise linear interpolation algorithm, this invention can smoothly and safely map precise auxiliary material dosages, frying temperatures, and stirring frequencies. This interpolation optimization strategy based on boundary saturation processing and range truncation effectively avoids the risk of control quantities exceeding limits under unknown operating conditions, significantly improving the stability of equipment operation and the uniformity of bead formation quality.

[0016] Furthermore, this invention constructs a feedforward prediction and error-driven adaptive feedback control architecture for the discharge rhythm based on multi-dimensional feature fusion. Instead of simply applying conventional time-series prediction models, this invention deeply concatenates the front-end generated roasting adaptation index, auxiliary material parameters, and equipment settings into a multi-dimensional feature vector. It then uses convolution and pooling operations to extract local correlation features between parameters, thereby accurately depicting the temporal distribution of the discharge rate in advance. More importantly, in the front-end and back-end rate matching stage, this invention designs a dynamic adaptive update mechanism for the feedforward and feedback weights, using real-time normalized absolute error to drive the smooth evolution of the feedback weights. This improved fusion control strategy effectively overcomes the shortcomings of a single feedforward model being susceptible to sudden disturbances and a single feedback control exhibiting severe lag, enabling high-precision dynamic matching between the weighing settings and the discharge gate rhythm of the packaging equipment as the front-end discharge rate fluctuates.

[0017] From an overall perspective, this invention breaks through the limitations of isolated control of each process in traditional production lines, forming a highly collaborative closed-loop system. The precise quantification of material characteristics at the front end not only determines the roasting process parameters in the middle stage, but these process parameters, along with the material characteristics, serve as core prerequisites, directly driving the prediction and dynamic adjustment of the cycle time in the back-end packaging process. Each innovative link is interconnected; the output data from the previous stage is deeply integrated and guides the algorithm execution in the next stage, enabling true global optimization of material preparation, roasting, and packaging through data flow. This deep process coupling and algorithmic collaboration not only significantly reduces the risk of material accumulation or equipment idling, but also fundamentally improves the intelligence level and overall efficiency of the fully automated production of tortoise shell glue beads.

Set to 0.05, Set it to 0.25.

[0021] Optionally, in order to make the weighting coefficients and It can continuously optimize as production data accumulates, and when the number of newly added valid records in the batch historical dataset reaches the preset update trigger threshold. At that time, online recalibration was performed on the weight coefficients: two sets of standardized regression analyses were re-performed based on the latest full historical batch dataset, and the absolute sensitivity was updated. and And recalculate according to the above normalization formula. and The updated and This information is immediately used for calculating the cooking compatibility index for subsequent batches; in this embodiment, Setting it to 20 means that an online weight recalibration is triggered every time 20 new valid historical records of processing batches are added.
