[0015] Embodiment 1

[0016] The present invention provides a method for optimizing the control of a beer fermentation device. Figure 1 Illustratively, the method comprises:

[0017] The method provided in the embodiment of the present disclosure includes:

[0018] Obtaining product design indicators of beer, wherein the product design indicators include alcohol content, wort concentration, and color;

[0019] Specifically, obtain the product design indicators of beer. Among them, the product design indicators include alcohol content, wort concentration, and chromaticity. Furthermore, the alcohol content is the volume percentage of ethanol in beer, expressed as a volume ratio at 20 degrees Celsius. For example, 50-degree beer means that at 20 degrees Celsius, 100 milliliters of beer contains 50 milliliters of ethanol. Wort concentration is used to measure the content of fermentable sugars before fermentation, and the wort concentration is the sugar content of malt in the raw materials when fermentation begins. Chromaticity is used to describe the color of beer, ranging from 1 to 40, and the higher the value, the darker the beer color.

[0020] Determine the yeast variety and expected fermentation time according to the product design index, and divide the expected fermentation time into fermentation stages according to preset time nodes to generate N fermentation stages, where N is an integer greater than 3;

[0021] Specifically, according to the alcohol content, wort concentration and chromaticity of the product design indicators, the yeast variety is determined, and the expected fermentation time of the yeast is determined. Among them, the yeast variety is the yeast variety used for brewing wine. The expected fermentation time is the time for yeast fermentation to make wine. Further, according to the preset time node, the expected fermentation time is divided into fermentation stages to generate N fermentation stages, wherein at least 3 fermentation stages are divided, and N is an integer greater than 3. For example, if the expected fermentation time is 12 hours, every 4 hours is divided into a preset time node. Furthermore, the preset time node is obtained by a technician in this field according to the actual situation.

[0022] Based on the product design indicators, the N fermentation stages are traced for expected products to generate an expected indicator sequence, wherein the expected indicator sequence includes N expected indicators, wherein the expected indicators include expected alcohol content, expected wort concentration, and expected color;

[0023] Specifically, a historical beer fermentation data set that meets the product design indicators is obtained. The historical beer fermentation data set is matched with N fermentation stages in sequence to obtain N historical fermentation stage data sets. Mean processing is performed on the N historical fermentation stage data sets respectively, and each mean calculation result is obtained as the expected indicator of each corresponding fermentation stage, thereby obtaining N expected indicators. An expected indicator sequence is constructed for the N expected indicators in the order of the fermentation stages. Among them, the expected indicators include expected alcohol content, expected wort concentration and expected color.

[0024] Acquire fermentation control parameters of a beer fermentation device and determine parameter adjustment thresholds, wherein the fermentation control parameters include temperature, pH value, and yeast quantity;

[0025] Specifically, according to the historical fermentation records, the fermentation control parameters of the beer fermentation device are obtained, and the parameter adjustment threshold is determined. Among them, the fermentation control parameters include temperature, pH value, and yeast quantity. The parameter adjustment threshold includes a temperature parameter adjustment threshold, a pH parameter adjustment threshold, and a yeast quantity parameter adjustment threshold. For example, the temperature parameter adjustment threshold is 28 to 30 degrees Celsius, the pH parameter adjustment threshold is 3 to 6, and the yeast quantity parameter adjustment threshold is 20 million to 30 million per milliliter.

[0026] According to the expected indicator sequence, the fermentation control parameters are optimized in sequence in the parameter adjustment thresholds to generate an optimal fermentation control parameter sequence;

[0027] Specifically, N beer quality evaluation functions are constructed according to the N expected indicators of the expected indicator sequence. The fermentation control parameters are randomly selected in each fermentation stage in the parameter adjustment threshold, and the fermentation control parameters are input into the beer fermentation predictor as input data to predict the fermentation situation, that is, the fermentation index. The fermentation index is evaluated by the beer quality evaluation function corresponding to the fermentation stage to obtain the evaluation result. The input data fermentation index when the evaluation result that meets the output is the highest is obtained, and the corresponding fermentation control parameter is obtained as the optimal fermentation control parameter. The N optimal fermentation control parameters of the N fermentation stages are used to construct the optimal fermentation control parameter sequence in the order of the fermentation stages.

[0028] Based on the yeast variety and the optimal fermentation control parameter sequence, the beer fermentation device is controlled to perform beer fermentation, and index data of the wort solution is collected according to the preset monitoring nodes to obtain a real-time stage index data set, wherein the real-time stage index data includes real-time alcohol content, real-time wort concentration and real-time chromaticity;

[0029] Specifically, based on the yeast variety and the optimal fermentation control parameter sequence, the optimal fermentation control parameter sequence is input to control the beer fermentation device to perform beer fermentation. N preset monitoring nodes for N fermentation stages are set, that is, the actual monitoring time is set, and the wort solution is subjected to index data collection through the corresponding sampling instrument to obtain N real-time stage index data. Then, a set of real-time stage index data for N fermentation stages is obtained, wherein the real-time stage index data includes real-time alcohol content, real-time wort concentration, and real-time chromaticity.

[0030] Generate a stage indicator deviation value based on the expected indicator sequence and the real-time stage indicator data set, and obtain stage compensation data according to the stage indicator deviation value;

[0031] Specifically, extract the real-time stage indicator data set of N fermentation stages in the real-time stage indicator data set. Extract the expected indicator sequence of N fermentation stages in the expected indicator sequence. Perform a difference comparison between the expected indicator sequence and the real-time stage indicator data set to obtain N stage indicator deviation values. Among them, the N stage indicator deviation values ​​include N alcohol content deviation values, N wort concentration deviation values, and N chromaticity deviation values. Further, obtain a preset indicator deviation threshold. Among them, the preset indicator deviation threshold is set based on the quality requirement accuracy and the indicator weight coefficient. When the quality requirement accuracy is greater, the preset indicator deviation threshold is smaller. When the indicator weight coefficient is greater, the preset indicator deviation threshold is smaller. Further, according to the alcohol content deviation threshold, wort concentration deviation threshold, and chromaticity deviation threshold of the preset indicator deviation threshold, the N alcohol content deviation values, the N wort concentration deviation values, and the N chromaticity deviation values ​​are judged to obtain a judgment result. Further, when there are N alcohol content deviation values ​​that do not meet the alcohol content deviation threshold or N wort concentration deviation values ​​that do not meet the wort concentration deviation threshold or N chromaticity deviation values ​​that do not meet any one of the chromaticity deviation thresholds, or when there are N alcohol content deviation values ​​that do not meet the alcohol content deviation threshold and N wort concentration deviation values ​​that do not meet the wort concentration deviation threshold and N chromaticity deviation values ​​that do not meet all of the chromaticity deviation thresholds, then the index deviation values ​​that do not meet the deviation thresholds are saved to obtain the stage index deviation values. Further, the historical index deviation values ​​and historical qualified compensation data in the historical beer fermentation control records are obtained, the compensation analysis model is trained, and the stage index deviation values ​​are input into the compensation analysis model for stage data compensation to obtain stage compensation data.

[0032] The optimal fermentation control parameter sequence is compensated and optimized according to the stage compensation data, and beer fermentation control is performed according to the optimal compensation fermentation control parameter sequence.

[0033] Specifically, when there is stage compensation data, the optimal fermentation control parameters of the adjacent stages in the optimal fermentation control parameter sequence are compensated according to the stage compensation data to generate the stage optimal compensation fermentation control parameters. The adjacent stage is the optimal fermentation control parameters of the next fermentation stage corresponding to the fermentation stage with the stage compensation data, so as to avoid the indicator deviation value of the previous fermentation stage from having too great an impact on the next fermentation stage. Furthermore, the indicator deviation value of each next fermentation stage of the optimal fermentation control parameter sequence is compensated according to the stage optimal compensation fermentation control parameter, and the same stage is replaced after compensation to generate the optimal compensation fermentation control parameter sequence.

[0034] Among them, this embodiment can solve the technical problem of insufficient control accuracy of beer fermentation in the prior art, resulting in poor beer fermentation effect, and achieve the technical effect of improving the accuracy and adaptability of beer fermentation control and improving the quality of beer fermentation.

[0035] The method provided in the embodiment of the present disclosure also includes:

[0036] Acquire a historical beer fermentation data set that meets the product design index;

[0037] Dividing the historical beer fermentation data set into stages according to the N fermentation stages to obtain N historical fermentation stage data sets;

[0038] The N historical fermentation stage data sets are processed in turn by averaging, and the mean calculation results are used as the expected index of each fermentation stage to obtain N expected indexes, and the expected index sequence is constructed according to the order of the fermentation stages.

[0039] like Figure 2 As shown, specifically, based on big data, a search is performed with product design indicators as constraints to obtain a historical beer fermentation data set that meets the product design indicators.

[0040] Furthermore, the historical beer fermentation data set is matched with the N fermentation stages in sequence to complete the stage data division of the historical beer fermentation data set, and obtain N historical fermentation stage data sets.

[0041] Furthermore, the data of each historical fermentation stage data set in the N historical fermentation stage data sets are processed by averaging, and each mean calculation result is obtained as the expected index of each corresponding fermentation stage, thereby obtaining N expected indexes. An expected index sequence is constructed for the N expected indexes according to the order of the fermentation stages.

[0042] Among them, based on the product design indicators, the expected product traceability is carried out for N fermentation stages to generate an expected indicator sequence. The indicators of each stage are met according to the expected indicator sequence to accurately achieve the expected indicators.

[0043] The method provided in the embodiment of the present disclosure also includes:

[0044] Selecting a first expected indicator of the first fermentation stage from the expected indicator sequence, and constructing a first beer quality evaluation function according to the first expected indicator, wherein the first expected indicator includes a first expected alcohol content, a first expected wort concentration, and a first expected chromaticity;

[0045] Randomly selecting a first fermentation control parameter from the parameter adjustment threshold, the first fermentation control parameter including a first temperature, a first pH value, and a first yeast quantity, and performing a stage index prediction on the first fermentation control parameter by a beer fermentation predictor to obtain a first fermentation index, the first fermentation index including a first predicted alcohol content, a first predicted wort concentration, and a first predicted chromaticity;

[0046] randomly selecting a second fermentation control parameter from the parameter adjustment threshold again, and obtaining a second fermentation index;

[0047] Evaluate the first fermentation index and the second fermentation index according to the first beer quality evaluation function to obtain a first evaluation result and a second evaluation result;

[0048] When the first evaluation result is greater than the second evaluation result, the first fermentation control parameter is used as the current optimal fermentation control parameter; when the first evaluation result is less than or equal to the second evaluation result, the second fermentation control parameter is used as the current optimal fermentation control parameter according to probability, wherein the probability decreases as the number of optimization searches increases;

[0049] Iterate the optimization in sequence until the current optimization times meet the preset optimization times threshold, and then output the current optimal fermentation control parameter as the first optimal fermentation control parameter;

[0050] The optimal fermentation control parameter sequence is obtained based on the first optimal fermentation control parameter.

[0051] Specifically, the first fermentation stage is the first fermentation stage in the N fermentation stages arranged in order of the fermentation stages. The first expected indicator of the first fermentation stage is selected from the expected indicator sequence. The first expected indicator includes a first expected alcohol content, a first expected wort concentration, and a first expected chromaticity. Further, a first beer quality evaluation function is constructed according to the first expected indicator.

[0052] Further, a first fermentation control parameter is randomly selected from the parameter adjustment threshold. The first fermentation control parameter includes a first temperature, a first pH value, and a first yeast quantity. Further, the beer fermentation predictor is used to predict the predicted fermentation condition of the fermentation stage through the fermentation control parameter. The first fermentation control parameter is obtained through the beer fermentation predictor, and the fermentation condition is predicted as a first fermentation index. The first fermentation index includes a first predicted alcohol content, a first predicted wort concentration, and a first predicted chromaticity.

[0053] Furthermore, a second fermentation control parameter is randomly selected from the parameter adjustment threshold again, and the second fermentation control parameter is input into the beer fermentation predictor to predict the fermentation situation and obtain a second fermentation index, wherein the second fermentation index includes a second predicted alcohol content, a second predicted wort concentration and a second predicted chromaticity.

[0054] Furthermore, the first fermentation index and the second fermentation index are evaluated respectively according to the first beer quality evaluation function of the first fermentation stage to determine whether the first fermentation index and the second fermentation index meet the requirements of the first fermentation stage, thereby obtaining a first evaluation result and a second evaluation result.

[0055] Furthermore, when the first evaluation result is greater than the second evaluation result, it means that for the first fermentation stage, the first fermentation index of the first evaluation result is better than the second fermentation index of the second evaluation result, and the first fermentation control parameter is used as the current optimal fermentation control parameter of the first fermentation stage. When the first evaluation result is less than or equal to the second evaluation result, it means that the second fermentation index of the second evaluation result is better than the first fermentation index of the first evaluation result, and the second fermentation control parameter is used as the current optimal fermentation control parameter according to probability. Among them, the probability is to improve the global search ability of the optimization in the early stage and to improve the accuracy of the optimization in the later stage. The probability decreases with the increase of the number of optimizations.

[0056] Furthermore, a fermentation control parameter is randomly selected from the parameter adjustment threshold, and the optimal fermentation control parameter is iteratively optimized in sequence, until the current optimization number meets the preset optimization number threshold, and the current optimal fermentation control parameter is output as the first optimal fermentation control parameter of the first fermentation stage. The preset optimization number threshold is obtained by a technician in this field according to the actual situation.

[0057] Furthermore, based on the method for obtaining the first optimal fermentation control parameter in the first fermentation stage, N optimal fermentation control parameters corresponding to the N fermentation stages are obtained, and the N optimal fermentation control parameters are used to construct an optimal fermentation control parameter sequence in the order of the fermentation stages.

[0058] Among them, according to the expected indicator sequence, the fermentation control parameters are optimized in turn in the parameter adjustment threshold value to generate the optimal fermentation control parameter sequence to improve the accuracy of fermentation control and improve the fermentation quality.

[0059] The method provided in the embodiment of the present disclosure also includes:

[0060] The first beer quality evaluation function expression is:

[0061] ;

[0062] in, is the beer quality of the i-th fermentation control parameter, , , is the weight coefficient of alcohol content, wort concentration and color, The first expected alcohol content, is the predicted alcohol content of the ith fermentation control parameter, is the first expected wort concentration, is the predicted wort concentration of the ith fermentation control parameter, is the first expected chromaticity, is the predicted color of the ith fermentation control parameter.

[0063] Specifically, the first beer quality evaluation function expression is:

[0065] in, is the beer quality of the i-th fermentation control parameter, , , is the weight coefficient of alcohol content, wort concentration and color, The first expected alcohol content, is the predicted alcohol content of the ith fermentation control parameter, is the first expected wort concentration, is the predicted wort concentration of the ith fermentation control parameter, is the first expected chromaticity, is the predicted color of the i-th fermentation control parameter. Further, when the first expected alcohol content Prediction of alcohol content with the i-th fermentation control parameter The smaller the difference, the higher the first expected wort concentration. Prediction of wort concentration with the i fermentation control parameters The smaller the difference, the first expected chromaticity Prediction of chromaticity with the i fermentation control parameters The smaller the difference is, the better the beer quality of the i-th fermentation control parameter is. The smaller it is, the better the fermentation control parameters are, the more the beer quality meets the standards, and the better the beer quality is.

[0066] Among them, constructing the first beer quality evaluation function according to the first fermentation index can improve the efficiency and accuracy of judging the beer quality.

[0067] The method provided in the embodiment of the present disclosure also includes:

[0068] Setting preset monitoring nodes based on the N fermentation stages to obtain N preset monitoring nodes;

[0069] At N preset monitoring nodes, the wort solution is sampled and tested by an alcohol measurement kit, a pH meter, and a colorimeter to obtain N real-time stage indicator data, and the real-time stage indicator data set is generated based on the N real-time stage indicator data.

[0070] Specifically, the actual monitoring time is set based on the N fermentation stages, that is, the preset monitoring nodes are set, and N preset monitoring nodes are obtained.

[0076] When the first alcohol content deviation value does not satisfy the alcohol content deviation threshold value and / or the first wort concentration deviation value does not satisfy the wort concentration deviation threshold value and / or the first chromaticity deviation value does not satisfy the chromaticity deviation threshold value, the indicator deviation value that does not satisfy the deviation threshold value is saved to obtain a first indicator deviation value;

[0077] The stage data is compensated according to the first indicator deviation value to obtain the stage compensation data.

[0078] Specifically, the first real-time stage indicator data of the first fermentation stage is selected from the real-time stage indicator data set, wherein the first real-time stage indicator data includes a first real-time alcohol content, a first real-time wort concentration and a first real-time chromaticity.

[0079] Further, the first expected indicator of the first fermentation stage in the expected indicator sequence is obtained. Further, the first stage indicator deviation value is obtained by performing a difference comparison between the first real-time stage indicator data and the first expected indicator. The first stage indicator deviation value includes a first alcohol content deviation value, a first wort concentration deviation value, and a first chromaticity deviation value.

[0080] Further, a preset indicator deviation threshold is obtained. The preset indicator deviation threshold is set based on the quality requirement accuracy and the indicator weight coefficient. When the quality requirement accuracy is greater, the preset indicator deviation threshold is smaller. When the indicator weight coefficient is greater, the preset indicator deviation threshold is smaller. Further, the first alcohol deviation value, the first wort concentration deviation value, and the first chromaticity deviation value are judged according to the alcohol deviation threshold, the wort concentration deviation threshold, and the chromaticity deviation threshold of the preset indicator deviation threshold to obtain a judgment result.

[0081] Further, when there is a first alcohol content deviation value that does not satisfy the alcohol content deviation threshold or the first wort concentration deviation value that does not satisfy the wort concentration deviation threshold or the first chromaticity deviation value that does not satisfy any one of the chromaticity deviation threshold, or when there is a first alcohol content deviation value that does not satisfy the alcohol content deviation threshold and the first wort concentration deviation value does not satisfy the wort concentration deviation threshold and the first chromaticity deviation value does not satisfy all of the chromaticity deviation thresholds, the indicator deviation value that does not satisfy the deviation threshold is saved to obtain the first indicator deviation value.

[0086] Constructing a compensation analysis model based on a BP neural network, and using the multiple historical indicator deviation values ​​and the multiple historical qualified compensation data as training data to perform supervised training on the compensation analysis model, so as to obtain a compensation analysis model in a converged state;

[0087] The first indicator deviation value is input into the compensation analysis model to obtain first compensation data, and the stage compensation data is obtained based on the first compensation data.

[0088] Specifically, according to the historical beer fermentation records, multiple historical indicator deviation values ​​and multiple historical qualified compensation data are obtained, and the historical indicator deviation values ​​and the historical qualified compensation data have a corresponding relationship.

First, a first historical indicator deviation value is randomly selected from multiple historical indicator deviation values ​​and multiple historical qualified compensation data as the first training data to perform supervised training on the compensation analysis model, and the first output result of the compensation analysis model, the first historical qualified compensation data, is obtained. Then, the first historical qualified compensation data of the first output result is compared with the first historical indicator deviation value of the first training data. When the comparison results are consistent, supervised training of the second set of training data is performed. When the comparison results are inconsistent, the data deviation between the first output result and the first training data is calculated, and the weight parameter of the compensation analysis model is optimized according to the data deviation, and then supervised training of the second training data is performed. Iterative supervised training is performed through the training data until the output result of the compensation analysis model tends to converge, and then the output of the compensation analysis model is verified through the verification data set to obtain a preset verification accuracy index. For example: the verification accuracy index is set to an output result accuracy of 95%. When the accuracy of the output result of the compensation analysis model is greater than the preset verification accuracy index, a trained compensation analysis model is obtained.

[0090] Furthermore, the first indicator deviation value is input into the compensation analysis model, the first compensation data is obtained through the output of the compensation analysis model, and multiple compensation data are obtained based on the method for obtaining the first compensation data, and the multiple compensation data are combined in the order of fermentation stages to obtain stage compensation data.

[0091] Among them, stage data compensation is performed according to the first indicator deviation value to obtain stage compensation data, which can improve the accuracy of beer fermentation control.

[0092] The method provided in the embodiment of the present disclosure also includes:

[0093] When there is stage compensation data, the optimal fermentation control parameters of adjacent stages in the optimal fermentation control parameter sequence are compensated according to the stage compensation data to generate the stage optimal compensated fermentation control parameters;

[0094] The optimal fermentation control parameter sequence is updated according to the optimal compensatory fermentation control parameter of the stage to generate an optimal compensatory fermentation control parameter sequence.

[0095] Specifically, when there is stage compensation data, the optimal fermentation control parameters of the adjacent stages in the optimal fermentation control parameter sequence are compensated according to the stage compensation data to generate the stage optimal compensated fermentation control parameters. The adjacent stage is the optimal fermentation control parameters of the next fermentation stage corresponding to the fermentation stage with the stage compensation data, and the compensation is performed to avoid the indicator deviation value of the previous fermentation stage from having too great an impact on the next fermentation stage. Furthermore, the compensation method is to add the values ​​to the optimal control parameters of the original stage to generate the stage optimal compensated fermentation control parameters.

[0096] Furthermore, the index deviation value of each next fermentation stage of the optimal fermentation control parameter sequence is compensated according to the optimal compensatory fermentation control parameter of the stage, and after compensation, the index deviation value is replaced in the same stage to generate the optimal compensatory fermentation control parameter sequence.

[0097] Among them, the optimal fermentation control parameter sequence is compensated and optimized according to the stage compensation data to improve the accuracy of beer fermentation control.
