Description

Technical Field

[0001] The present invention relates to the field of pot still, and in particular to a pot still abnormality early warning method, system and intelligent terminal. Background Art

[0002] The pot still is a traditional distillation equipment, which is widely used in the production of whiskey, cognac and other spirits. The pot still includes a heating container, a steam outlet pipe, a condenser and a preheater for preheating the heating container. The heating container outlets steam to the condenser through the steam outlet pipe.

[0003] When the pot still needs to distill the fermented liquid, the heating container is preheated by the preheater, the fermented liquid is placed in the heating container and heated, so that the fermented liquid forms alcohol vapor which is transported to the condenser through the steam outlet pipe and condensed into liquid in the condenser and then collected in the receiving container, thereby separating the alcohol and other volatile components.

[0004] Since the fermented liquid contains surfactants with foaming properties, these substances will produce a lot of foam after heating during the distillation process. It is not easy for the administrator to understand the foam situation in time, resulting in a lot of foam on the liquid, which can easily reduce the distillation efficiency. Summary of the invention

[0005] In order to improve the efficiency of pot still, the present invention provides a pot still abnormality warning method, system and intelligent terminal.

[0006] In a first aspect, the present invention provides a pot distillation abnormality warning method, which adopts the following technical solution:

[0007] A pot distillation abnormality early warning method, comprising:

[0008] Acquire image detection information and liquid information of the distilled liquid;

[0009] Determine the foam height value according to the image detection information and the preset foam characteristics;

[0010] The foam rising speed is calculated based on the foam height value and the preset unit time analysis;

[0011] Retrieving the reference existence time based on the liquid information;

[0012] When the foam height value exceeds a preset reference height value, the existence time of the foam is obtained;

[0013] Calculate the difference between the existence time and the reference existence time and use it as the time deviation value;

[0014] Calculate the product of the foam rising speed and the time deviation value and use it as the moving distance;

[0015] When the moving distance exceeds the preset reference moving distance, a preset prompt message is output to the terminal held by the administrator.

[0016] By adopting the above technical solution, the existence of foam is determined through image detection information, and when the foam height exceeds the reference height value without bursting and the foam movement distance exceeds the reference movement distance, a prompt message is output to the terminal held by the manager, thereby prompting the manager to deal with the generation of foam in time, thereby reducing the probability that the manager will not be able to understand the foam situation in time, resulting in a decrease in the efficiency of pot distillation.

[0017] Optionally, a pot distillation abnormality warning method further includes:

[0018] When the foam height value does not exceed the reference height value, obtaining the current atmospheric pressure value of the environment where the distilled liquid is located;

[0019] Determine the reference temperature value according to the liquid information and the current atmospheric pressure value;

[0020] Get the actual temperature value of the distilled liquid;

[0021] Calculate the difference between the actual temperature value and the reference temperature value and use it as the temperature deviation value;

[0022] When the temperature deviation value exceeds the preset reference temperature deviation value, the difference between the foam height value and the reference height value is calculated and used as the height deviation value;

[0023] Determine the temperature rise time according to the temperature deviation value and the preset heating temperature;

[0024] Calculate the product of the temperature rise time and the foam rise speed and use it as the estimated foam rise distance;

[0025] When the estimated rising distance of the foam exceeds the height deviation value, the total amount of oil dripping is determined based on the image detection information and the foam characteristic analysis, and the total amount of oil dripping is used as the oil dripping control parameter;

[0026] The oil dripping control parameters are output to the preset oil dripping device, and the prompt information is output to the terminal held by the administrator.

[0027] By adopting the above technical solution, when the temperature of the liquid has not reached the reference temperature value, the foam still tends to increase, then the rising distance of the foam is estimated, and when the estimated rising distance of the foam exceeds the height deviation value, the foam generated on the liquid is eliminated through the oil dripping device, so that it is not easy for the foam to insulate the distillation of the liquid to reduce the efficiency of the liquid distillation, thereby improving the efficiency of the pot distillation.

[0028] Optionally, the method for determining the total amount of oil dripping includes:

[0029] Based on the foam features, the foam estimated circle center, the foam coverage area corresponding to the foam estimated circle center, and the number of foam circle centers are identified from the image detection information;

[0030] Determine the initial total amount of oil dripping based on the number of bubble circle centers and the bubble coverage;

[0031] Based on the foam coverage, the estimated foam center corresponding to the uncovered foam is selected and used as the marked foam center;

[0032] According to the number of bubble circle centers, the number of marked bubbles corresponding to the marked bubble circle centers is retrieved;

[0033] Calculate the adjustment coefficient based on the number of marked bubbles and the number of bubble circle centers;

[0034] The total amount of oil dripping is determined based on the initial total amount of oil dripping and the adjustment factor.

[0035] By adopting the above technical solution, the total amount of oil drops is determined by the parameters of the foam on the liquid and the corresponding coverage of the foam, so that the foam can be eliminated with the minimum total amount of oil drops, thereby reducing energy consumption and improving the efficiency of foam elimination.

[0036] Optionally, the method further includes the following steps after taking the total amount of oil dripping as the oil dripping control parameter:

[0037] Calculate the quotient of the total amount of oil drops and the marked foam quantity and use it as the benchmark oil drops;

[0038] Calculate the corresponding correction coefficient according to the foam coverage corresponding to the marked foam center and the preset reference coverage;

[0039] The adjusted oil dripping amount corresponding to the center of the marked foam circle is calculated according to the correction coefficient and the reference oil dripping amount, and the total oil dripping amount is re-determined according to the adjusted oil dripping amount;

[0040] Determine the position of the marking foam corresponding to the center of the marking foam circle according to the image detection information;

[0041] Determine the oil dripping sequence based on the foam coverage, marked foam position and liquid information;

[0042] The oil dripping sequence is combined with the updated total amount of oil dripping to form new oil dripping control parameters and output to the oil dripping device.

[0043] By adopting the above technical solution, the foam coverage range of the foam circle centers with different marks is analyzed to obtain the corresponding adjusted oil dripping amount and oil dripping sequence and output them to the oil dripping device, so that the foam with a large coverage range and stronger heat insulation ability can be eliminated first, thereby improving the efficiency of pot distillation.

[0044] Optionally, the method further includes forming new oil dripping control parameters and outputting the parameters to the oil dripping device, which are specifically as follows:

[0045] Determine the density of the dripping oil according to the liquid information and the reference temperature value;

[0046] Update and adjust the oil dripping amount according to the oil dripping density;

[0047] Determine the oil drip height according to the liquid information and the updated adjusted oil drip amount;

[0048] Obtain the steam rising direction and steam rising speed in the preset heating container;

[0049] Update the steam rising direction according to the marked foam position, the preset distillation internal shape and the preset liquid center position;

[0050] Update the oil drip height according to the steam rising speed;

[0051] Determine the oil dripping position according to the updated steam rising direction and the updated oil dripping height;

[0052] The oil dripping control parameter is added to the oil dripping control parameter according to the oil dripping position to update the oil dripping control parameter, and the updated oil dripping control parameter is output to the oil dripping device.

[0053] By adopting the above technical solution, the oil dripping position is determined by the steam conditions in the pot still, so that the oil dripping device is not prone to data deviation in the oil dripping position under the influence of steam.

[0054] Optionally, the method further includes the following specific steps after the updated oil dripping control parameter is output to the oil dripping device:

[0055] The base viscosity value of the oil corresponding to the drop oil density is obtained when the center of the liquid does not fall into the foam coverage area corresponding to the marked foam circle center;

[0056] Retrieve the liquid viscosity value according to the liquid information;

[0057] When the reference viscosity value is greater than the liquid viscosity value, the corresponding straight-line distance is calculated based on the marked foam center and the liquid center position and used as the reference offset distance;

[0058] Arrange in reverse order based on the benchmark offset distance, and select the marked foam circle center corresponding to the smallest benchmark offset distance as the priority oil dripping circle center;

[0059] According to the liquid viscosity value, the oil drop height corresponding to the center of the preferential oil drop circle and the oil drop amount, the preferential diffusion range is determined;

[0060] The reference offset distance of the center of the priority oil dripping circle falls into the diffusion range, and the oil dripping adjustment sequence is determined according to the reference offset distances arranged in reverse order;

[0061] The oil dripping sequence in the oil dripping control parameter is replaced according to the oil dripping adjustment sequence to form a new oil dripping control parameter, and the new oil dripping control parameter is output to the oil dripping device.

[0062] By adopting the above technical solution, when the center position of the liquid does not fall into the foam coverage range corresponding to the marked foam center, the liquid cannot be suppressed from generating bubbles. The oil drip adjustment sequence is readjusted by comparing the liquid and the oil and the reference offset distance and the falling within the diffusion range, so that the oil can be diffused to cover the center of the liquid, thereby making it difficult for the liquid to re-generate bubbles in the process of reducing the foam.

[0063] Optionally, the step of outputting the new oil dripping control parameter to the oil dripping device is further included, which is as follows:

[0064] Determine the oil dripping time according to the updated oil dripping height;

[0065] Determine the liquid distillation amount per unit time according to the reference temperature value and liquid information;

[0066] Calculate the product of the dripping time and the liquid distillation amount and use it as the total liquid distillation amount;

[0067] Calculate the difference between the total amount of liquid distillation and the preset reference liquid amount and use it as the remaining distillation amount;

[0068] Determine the oil drop information according to the oil drop density;

[0069] Determine the maximum total amount of oil dripping according to the remaining distillation volume and oil dripping information;

[0070] Calculate the difference between the maximum total amount of oil dripping and the updated total amount of oil dripping and use it as the oil amount deviation value;

[0071] When the oil volume deviation value does not fall within the preset reference deviation range, the amount of liquid increase is determined according to the oil volume deviation value;

[0072] Determine the preheating temperature value according to the reference temperature value;

[0073] According to the increase in liquid volume, the preset preheating device is controlled to preheat at the preheating temperature value, and the preheated increase in liquid volume is transported to the heating container;

[0074] Calculate the difference between the preheating temperature value and the reference temperature value and use it as the temperature deviation value;

[0075] Calculate the quotient of the temperature deviation value and the heating temperature and use it as the heating time;

[0076] The adjustment time is updated according to the heating time, and the updated adjustment time is added to the oil dripping control parameter to form a new oil dripping control parameter and output to the oil dripping device.

[0077] By adopting the above technical scheme, the reduction of liquid during distillation within the dripping time is analyzed to obtain the increase in liquid, and the dripping time of the oil dripping device is readjusted according to the increase in liquid. When the liquid is input into the pot distiller, the liquid needs to be reheated, and the amount of steam generated by heating the liquid is reduced, so that it is not easy for the dripping data to deviate when the steam amount is reduced.

[0078] Optional method to determine the diffusion range:

[0079] , is the diffusion range, is the diameter corresponding to the diffusion range, is the gravitational acceleration of the oil drop, Adjust the oil dripping amount corresponding to the center of the priority oil dripping circle. To adjust the oil drop radius corresponding to the oil drop amount, is the viscosity of the liquid, It is the oil dripping height corresponding to the center of the priority oil dripping circle.

[0080] In a second aspect, the present application provides a pot distillation abnormality warning system, which adopts the following technical solution:

[0081] A pot distillation abnormality early warning system, comprising:

[0082] An acquisition module is used to acquire image detection information, liquid information, existence time, current atmospheric pressure value, actual temperature value, steam rising direction, steam rising speed and reference viscosity value;

[0084] The program in the processor memory can be loaded and executed by the processor to implement a pot distillation abnormality warning method.

[0085] In a third aspect, the present application provides a smart terminal, which adopts the following technical solution:

[0086] An intelligent terminal comprises a memory and a processor. The memory stores a computer program which can be loaded by the processor and executes a pot distillation abnormality early warning method.

[0087] In summary, the present application includes at least one of the following beneficial technical effects:

[0088] 1. Determine the existence of foam through image detection information, and if the foam height exceeds the reference height value but does not break and the foam movement distance exceeds the reference movement distance, output prompt information to the terminal held by the manager, so that the manager can deal with the generation of foam in time, and it is not easy for the foam to affect the efficiency of distillation, thereby improving the efficiency of liquid distillation;

[0089] 2. By analyzing the foam coverage of different marked foam centers, the corresponding adjustment of oil dripping amount and oil dripping sequence is obtained and output to the oil dripping device, so that the foam with a large coverage and stronger heat insulation ability can be eliminated first, thereby improving the efficiency of pot distillation;

[0090] 3. When the center position of the liquid does not fall within the foam coverage range corresponding to the marked foam circle center, the liquid cannot be suppressed from generating bubbles. The oil drip adjustment sequence is readjusted by comparing the liquid with the oil and the fall of the reference offset distance within the diffusion range, so that the oil can be diffused to cover the center of the liquid, thereby preventing the liquid from re-generating bubbles in the process of reducing the foam.

[0096] The following is combined with Figures 1 to 5 The present invention is further described in detail with examples.

[0097] A method for abnormal warning of pot stills, when a large amount of foam is generated and stacked on the liquid surface, causing the foam to rise continuously, the foam situation in the pot still is detected and analyzed to output warning information, and further adjustments are made according to the temperature of the pot still distilled liquid, the type of liquid, the foam parameters and the steam parameters, so that the foam is not likely to insulate the distilled liquid and cause low distillation efficiency, thereby improving the efficiency of the pot still.

[0098] Reference Figure 1 The present application embodiment discloses a pot distillation abnormality warning method, comprising the following steps:

[0099] Step S100: Acquire image detection information and liquid information of the distilled liquid.

[0100] Image detection information refers to the image of liquid taken when the pot still is distilling the liquid, and the image of the liquid distillation is taken by a camera preset on the pot still as image detection information. Liquid information refers to the relevant parameters corresponding to the liquid preset in the pot still for fermentation, and the liquid information is obtained by combining the parameters such as liquid density, liquid viscosity value and bubble existence time corresponding to the fermentation liquid input in advance by the operator.

[0101] Step S101: determining a foam height value according to image detection information and preset foam features.

[0102] The foam feature refers to the feature corresponding to the foam on the surface of the liquid in the pot still, which is set and stored in advance by the operator. The foam height value refers to the height between the foam generated on the surface of the liquid in the pot still and the liquid surface. The outline size corresponding to the foam feature is selected from the image detection information, and the size parameter of the foam is calculated through the outline size, and then the corresponding height parameter is retrieved from the size parameter as the foam height value.

[0103] Step S102: Calculate the foam rising speed according to the foam height value and the preset unit time.

[0104] The foam rising speed refers to the speed at which the foam on the liquid surface rises. The difference between the two foam height values ​​before and after the update in a preset unit time is calculated, and then the quotient of the difference and the unit time is calculated and used as the foam rising speed. The unit time refers to the time corresponding to the speed of detecting the rise of a single bubble. The unit time is preset by a person skilled in the art and will not be described in detail here.

[0105] Step S103: Retrieve the reference existence time based on the liquid information.

[0106] The reference existence time refers to the maximum time that the foam generated by the liquid information during the distillation process can exist, and the parameters corresponding to the bubbles generated are retrieved from the liquid information as the reference existence time.

[0107] Step S104: when the foam height value exceeds a preset reference height value, obtaining the existence time of the foam.

[0108] The reference height value refers to the maximum height that the foam is allowed to rise, which is set in advance by the operator and stored. The existence time refers to the time that the foam has existed on the liquid surface. When the foam height value exceeds the reference height value, it means that the foam will reduce the distillation effect of the liquid. The time is marked when the foam appears, and the difference between the current time and the marked time is calculated and used as the existence time.

[0109] Step S105: Calculate the difference between the existence time and the reference existence time and use it as the time deviation value.

[0110] The time deviation value refers to the deviation value between the existence time and the reference existence time, and is calculated as the time deviation value by the difference between the existence time and the reference existence time.

[0111] Step S106: Calculate the product of the foam rising speed and the time deviation value and use it as the moving distance.

[0112] The moving distance refers to the distance that the foam can move within the time deviation value, and is calculated by calculating the product of the foam rising speed and the time deviation value as the moving distance.

[0113] Step S107: When the moving distance does not exceed the preset reference moving distance, continue to determine the foam height value.

[0114] The reference moving distance refers to the maximum distance that the foam can move on the reference height value, which is set and stored by the operator in advance. When the moving distance exceeds the reference moving distance, it means that the foam breaks within the unit time and does not reduce the distillation effect of the liquid, and then the process continues to jump to step S101.

[0115] Step S108: When the moving distance exceeds the preset reference moving distance, a preset prompt message is output to the terminal held by the administrator.

[0116] The prompt information refers to the information that reminds the manager that there are too many bubbles that affect the distillation effect. It is set and stored in advance by the operator. When the moving distance exceeds the reference moving distance, it means that the foam will reduce the distillation effect of the liquid, and the prompt information is output to the terminal held by the manager, so as to remind the manager to deal with the generation of foam in time, thereby reducing the probability that the manager is not easy to understand the foam situation in time, resulting in a decrease in the efficiency of pot distillation.

[0117] Reference Figure 2 , a pot distillation abnormality early warning method, further comprising:

[0118] Step S200: When the foam height value does not exceed the reference height value, the current atmospheric pressure value of the environment where the distilled liquid is located is obtained.

[0119] The current atmospheric pressure value refers to the atmospheric pressure value of the environment in which the pot still is located when the liquid is distilled. When the foam height value does not exceed the reference height value, it means that the current foam will not provide insulation for the distillation effect of the liquid, resulting in low distillation efficiency. Therefore, the GPS preset on the pot still is used for positioning, and the atmospheric pressure value corresponding to the positioned position is queried through the network as the current atmospheric pressure value.

[0120] Step S201: determining a reference temperature value according to liquid information and a current atmospheric pressure value.

[0121] The reference temperature value refers to the maximum temperature value of the liquid corresponding to the liquid information when distilling under the current atmospheric pressure value. The reference temperature value is matched from the preset liquid database through the liquid information and the current atmospheric pressure value. The liquid database stores the maximum distillation temperature values ​​corresponding to different liquid information and the current atmospheric pressure value, and also stores the total amount of oil drops corresponding to the area covered by different bubbles on the liquid. The liquid database is set manually and will not be described in detail here.

[0122] Step S202: Acquire the actual temperature value of the distilled liquid.

[0123] The actual temperature value refers to the actual temperature value of the liquid during distillation, and the parameter obtained by detecting the temperature sensor preset on the pot still is used as the actual temperature value.

[0124] Step S203: Calculate the difference between the actual temperature value and the reference temperature value and use it as the temperature deviation value.

[0125] The temperature deviation value refers to the deviation value between the actual temperature value and the reference temperature value. The difference between the actual temperature value and the reference temperature value is calculated and used as the temperature deviation value.

[0126] Step S204: When the temperature deviation value does not exceed the preset reference temperature deviation value, continue to obtain the real-time temperature value.

[0127] The reference temperature deviation value refers to the minimum temperature deviation value required for the liquid to start to generate bubbles during the distillation process. It is set and stored by the operator in advance. When the temperature deviation value does not exceed the reference temperature deviation value, it means that the liquid will not generate bubbles as the temperature rises, and the real-time temperature value continues to be obtained.

[0128] Step S205: When the temperature deviation value exceeds a preset reference temperature deviation value, a difference between the foam height value and the reference height value is calculated and used as the height deviation value.

[0129] The height deviation value refers to the deviation value between the foam height value and the reference height value. When the temperature deviation value exceeds the reference temperature deviation value, it means that the liquid will generate bubbles as the temperature rises. The difference between the foam height value and the reference height value is calculated and used as the height deviation value.

[0130] Step S206: determining the temperature rise time according to the temperature deviation value and the preset heating temperature.

[0131] The heating temperature refers to the temperature that rises when the pot still is heated per unit time, which is set and stored by the operator in advance. The temperature rise time refers to the time required for the real-time temperature value to reach the reference temperature value, which is calculated by dividing the temperature deviation value by the heating temperature and used as the temperature rise time.

[0132] Step S207: Calculate the product of the temperature rise time and the foam rise speed and use it as the estimated foam rise distance.

[0133] The estimated foam rising distance refers to the distance the foam is estimated to rise during the temperature rising time. The product of the temperature rising time and the foam rising speed is calculated and used as the estimated foam rising distance.

[0134] Step S208: When the estimated foam rising distance does not exceed the height deviation value, continue to determine the foam height value.

[0135] When the estimated rising distance of the foam does not exceed the height deviation value, it means that the foam will not provide insulation for the liquid distillation during the temperature rising process, resulting in low distillation efficiency, and then continue to jump to execute step S101.

[0136] Step S209: when the estimated rising distance of the foam exceeds the height deviation value, the total amount of oil dripping is determined according to the image detection information and the foam characteristic analysis, and the total amount of oil dripping is used as the oil dripping control parameter.

[0137] The total amount of oil dripping refers to the total amount of oil that needs to be added to the foam produced when the oil dripping device is used to control the liquid distillation. When the estimated rising distance of the foam exceeds the height deviation value, it means that the foam will cause heat insulation to the liquid distillation, resulting in low distillation efficiency. The image detection information and foam characteristics are analyzed to obtain the total amount of oil dripping. The specific analysis process refers to steps S300 to S305. The oil dripping control parameter refers to the parameter for controlling the oil dripping device to drip oil into the liquid distilled in the pot still. The parameter corresponding to the total amount of oil dripping is used as the oil dripping control parameter. The oil dripping device refers to a straw that is preset on the pot still and is used to reduce the foam produced by the distilled liquid. In this embodiment, the oil can be edible oil or other oil that does not react with the fermented liquid.

[0138] Step S210: outputting the oil dripping control parameters to the preset oil dripping device, and outputting prompt information to the terminal held by the administrator.

[0139] By outputting the oil dripping control parameters to the preset oil dripping device, the oil dripping device can be controlled to drip oil to reduce the foam generated by the distilled liquid of the kettle rectifier, and the prompt information is output to the terminal held by the administrator.

[0140] Reference Figure 3 , the method for determining the total amount of oil dripping includes:

[0141] Step S300: Identifying the estimated foam center, the foam coverage corresponding to the estimated foam center, and the number of foam centers from the image detection information based on the foam features.

[0142] The estimated center of the foam refers to the estimated center of the irregular foam generated when the pot still distills the liquid. The foam coverage refers to the coverage area corresponding to the foam with the estimated center of the foam as the center. The number of foam centers refers to the number of estimated foam centers appearing in the image detection information. The foam features are framed out from the image detection information, and the smallest circle is matched with the framed shape. The center of the smallest circle is used as the estimated center of the foam, and the foam coverage is calculated using the diameter parameter corresponding to the smallest circle. The number of foam centers appearing in the image detection information is then counted to obtain the number of foam centers.

[0143] Step S301: Determine the initial total amount of oil dripping according to the number of bubble circle centers and the bubble coverage.

[0144] The initial total amount of oil dripping refers to the total amount of oil dripping initially controlled by the oil dripping device. The product of the foam coverage range and the number of foam circle centers is calculated and used as the total coverage amount. The initial total amount of oil dripping is matched from the liquid database through the total coverage amount.

[0145] Step S302: based on the foam coverage range, the estimated foam center corresponding to the uncovered foam is selected and used as the marked foam center.

[0146] The marked bubble center refers to the estimated bubble center corresponding to the uncovered bubble. The estimated bubble center that does not fall into the bubble coverage range is selected as the marked bubble center based on the falling condition of the estimated bubble center in the bubble coverage range corresponding to other estimated bubble centers.

[0147] Step S303: according to the number of bubble circle centers, retrieve the number of marked bubbles corresponding to the marked bubble circle centers.

[0148] The number of marked bubbles refers to the number of the centers of the marked bubbles in the image detection information, and the number corresponding to the centers of the marked bubbles is retrieved from the number of bubble centers as the number of marked bubbles.

[0149] Step S304: Calculate the adjustment coefficient according to the number of marked bubbles and the number of bubble circle centers.

[0150] The adjustment coefficient is used to adjust the initial total amount of oil dripping. The quotient of the number of marked bubbles and the number of bubble center points is calculated and used as the adjustment coefficient.

[0151] Step S305: determining the total amount of oil dripping according to the initial total amount of oil dripping and the adjustment coefficient.

[0152] By calculating the product of the initial total amount of oil dripping and the adjustment coefficient and taking it as the total amount of oil dripping, the foam can be eliminated with the minimum total amount of oil dripping, thereby reducing energy consumption and improving the efficiency of foam elimination.

[0153] Reference Figure 4 , and further includes the following steps after the total amount of oil dripping is used as the oil dripping control parameter:

[0154] Step S400: Calculate the quotient of the total amount of oil drops and the marked foam amount and use it as the reference oil drop amount.

[0155] The reference oil drop volume refers to the average oil drop volume when oil is dropped on the center of each marked bubble circle. The quotient of the total oil drop volume and the number of marked bubbles is calculated and used as the reference oil drop volume.

[0156] Step S401: Calculate the corresponding correction coefficient according to the foam coverage area corresponding to the marked foam circle center and the preset reference coverage area.

[0157] The reference coverage range refers to the foam coverage range corresponding to the reference oil drop volume, which is formed by the operator's pre-setting and storage. The correction coefficient refers to the coefficient used to correct the reference oil drop volume, which is calculated by calculating the quotient of the foam coverage range corresponding to each marked foam circle center and the reference coverage range and using it as the correction coefficient corresponding to the marked foam circle center.

[0158] Step S402: Calculate the adjusted oil dripping amount corresponding to the center of the marked bubble circle according to the correction coefficient and the reference oil dripping amount, and redetermine the total oil dripping amount according to the adjusted oil dripping amount.

[0159] The adjusted oil dripping amount refers to the oil dripping amount corresponding to each marked bubble circle center after adjustment of the correction coefficient. The product of the base oil dripping amount and the correction coefficient corresponding to the marked bubble circle center is calculated as the adjusted oil dripping amount, and the sum of the adjusted oil dripping amounts corresponding to each marked bubble circle center is calculated as the new total oil dripping amount.

[0160] Step S403: determining the position of the mark bubble corresponding to the center of the mark bubble according to the image detection information.

[0161] The marked foam position refers to the position corresponding to the center of the marked foam circle. The marked point corresponding to the center of the marked foam circle is marked through image detection information, and the marked foam position is obtained through the preset reference marked point and the marked point. The reference marked point refers to the reference point used to calculate the corresponding center of the marked foam circle, which is set and stored in advance by the operator.

[0162] Step S404: Determine the oil dripping order according to the foam coverage, the marked foam position and the liquid information.

[0163] The oil dripping sequence refers to the order in which the oil dripping device is controlled to drip oil to each marked foam position. The oil dripping sequence is determined by analyzing the foam coverage, marked foam position and liquid information. For specific analysis steps, refer to steps S4041 to S404C.

[0164] Step S405: combining the oil dripping sequence with the updated total amount of oil dripping to form a new oil dripping control parameter and outputting it to the oil dripping device.

[0165] By combining the oil dripping sequence with the parameters corresponding to the updated total amount of oil dripping to form new oil dripping control parameters and outputting them to the oil dripping device, the foam with a large coverage area and stronger heat insulation ability can be eliminated first, thereby improving the efficiency of pot distillation.

[0166] Further, the method for determining the oil dripping sequence includes:

[0167] Step S4041: Arrange in positive order according to the foam coverage area corresponding to the center of the marked foam circle, and determine the oil dripping path according to the positive order and the marked foam position.

[0168] The oil dripping path refers to the path for controlling the oil dripping device to drip oil to each marked foam center. The oil dripping path is obtained by arranging the foam coverage areas corresponding to the marked foam centers from large to small and by the straight lines between the marked foam positions corresponding to the marked foam centers after arrangement.

[0169] Step S4042: Determine whether there is a marked bubble circle whose center is located in the oil dripping path.

[0170] By determining whether there is a marking bubble center located on the oil dripping path, it is possible to determine whether there are other marking bubble centers on the straight line between the two marking bubble centers.

[0171] Step S4043: If there is no bubble circle with the center of the bubble marked on the oil dripping path, then continue to execute step S405.

[0172] When there is no marked bubble circle center located in the oil dripping path, it means that there is no other marked bubble circle center on the straight line between the two marked bubble circle centers, and then continue to execute step S405.

[0173] Step S4044: There is a marked foam center on the oil dripping path, and the foam center and the diffused foam center are determined according to the foam coverage.

[0174] Selecting the foam center refers to selecting the marked foam center on the oil dripping path. The diffusion foam center refers to the marked foam center that preferentially drips oil and diffuses the oil. When there is a marked foam center located on the oil dripping path, it means that there are other marked foam centers on the straight line between the two marked foam centers. The marked foam center with the largest foam coverage on the oil dripping path is used as the diffusion foam center, and the other marked foam centers on the oil dripping path are used as the selected foam centers.

[0175] Step S4045: Determine the oil drop density according to the liquid information and the reference temperature value, and obtain the reference viscosity value of the oil corresponding to the oil drop density.

[0176] The oil dripping density refers to the density of the oil used by the oil dripping device, and the reference viscosity value refers to the viscosity of the oil corresponding to the total amount of oil dripping. The information of the oil used is matched from the preset oil dripping database through the liquid information and the reference temperature value, and the density of the oil is retrieved from the oil information as the oil dripping density, and the viscosity value of the oil is retrieved from the oil information as the reference viscosity value. The oil dripping database stores the information of the oil corresponding to different liquid information and reference temperature values, and also stores the height of the oil dripping corresponding to different liquid information and the adjusted oil dripping amount, and the time of the oil dripping corresponding to different oil dripping heights. The oil dripping database is set manually and will not be elaborated here.

[0177] Step S4046: Retrieve the liquid viscosity value according to the liquid information.

[0178] The liquid viscosity value refers to the viscosity value corresponding to the liquid information, and the viscosity value of the liquid is retrieved from the liquid information as the liquid viscosity value.

[0179] Step S4047: When the reference viscosity value is greater than the liquid viscosity value, determine the oil dripping height according to the liquid information and the updated adjusted oil dripping amount.

[0180] The oil dripping height refers to the height at which the oil dripping device drips oil. The oil dripping height is matched from the oil dripping database through the liquid information and the updated adjusted oil dripping amount.

[0181] Step S4048: Determine the diffusion range according to the liquid viscosity value, the oil drop height and the oil drop amount.

[0182] The diffusion range refers to the range of horizontal diffusion of oil droplets falling on the liquid. The diffusion range is calculated in the preset calculation database through the liquid viscosity value, oil drop height and adjustment of oil drop amount. The calculation method of the calculation database is:

[0183] , is the diffusion range, is the diameter corresponding to the diffusion range, is the gravitational acceleration of the oil drop, Adjust the oil dripping amount corresponding to the center of the priority oil dripping circle. To adjust the oil drop radius corresponding to the oil drop amount, is the viscosity of the liquid, It is the oil dripping height corresponding to the center of the priority oil dripping circle.

[0184] For example: the gravitational acceleration of an oil droplet for , adjust the oil dripping amount corresponding to the center of the oil dripping circle for , adjust the oil drop radius corresponding to the oil drop amount for , the oil drop height corresponding to the center of the oil drop circle is preferred 0.1m, liquid viscosity value for ,but

[0185] .

[0186] Step S4049: When the reference viscosity value is greater than the liquid viscosity value, the difference between the diffusion range and the foam coverage range corresponding to the center of the diffusion foam circle is calculated and used as the diffusion deviation value.

[0187] The diffusion deviation value refers to the deviation value of the straight line between the diffusion range and the foam coverage range corresponding to the center of the diffusion foam circle. When the benchmark viscosity value is greater than the liquid viscosity value, it means that the oil diffusion range is greater than the corresponding foam coverage range. In this case, half of the difference between the diameter corresponding to the diffusion range and the diameter of the foam coverage range corresponding to the center of the diffusion foam circle is calculated and used as the diffusion deviation value.

[0188] Step S404A: Determine the diffusion distance according to the selected bubble center and the diffused bubble center.

[0189] The diffusion distance refers to the distance that can be diffused between the center of the selected foam circle and the center of the diffusion foam circle. The straight-line distance between the center of the selected foam circle and the center of the diffusion foam circle is calculated, and then the sum of the radii of the foam coverage range corresponding to the center of the selected foam circle and the center of the diffusion foam circle is calculated. The difference between the sum and the straight-line distance is calculated and used as the diffusion distance.

[0190] Step S404B: when the diffusion deviation value is not greater than the diffusion distance, determining the oil dripping sequence according to the oil dripping path and the marked bubble position.

[0191] When the diffusion deviation value is not greater than the diffusion distance, it means that the oil dripping corresponding to the center of the diffusion foam circle will not cause the foam at the selected foam center to break, then the order of dripping oil on the marked foam positions along the oil dripping path is used as the oil dripping order.

[0192] Step S404C: When the diffusion deviation value is greater than the diffusion distance, the oil dripping path is updated according to the selected bubble circle center, and the oil dripping sequence is determined according to the updated oil dripping path and the marked bubble position.

[0193] When the diffusion deviation value is greater than the diffusion distance, it means that the oil dripping corresponding to the center of the diffusion foam circle will cause the foam at the selected foam center to burst. In this case, the path corresponding to the selected foam center in the oil dripping path will be cancelled to form a new oil dripping path. The order of dripping oil on the remaining marked foam positions using the updated oil dripping path will be used as the oil dripping order.

[0194] Reference Figure 5 , and also includes the steps of forming new oil dripping control parameters and outputting them to the oil dripping device, which are as follows:

[0195] Step S500: Determine the oil drop density according to the liquid information and the reference temperature value.

[0196] The oil dripping density refers to the density of the oil used by the oil dripping device. The information of the oil used is matched from a preset oil dripping database through liquid information and a reference temperature value, and the density of the oil is retrieved from the oil information as the oil dripping density.

[0197] Step S501: updating and adjusting the oil dripping amount according to the oil dripping density and the oil dripping amount.

[0198] By calculating the quotient between the oil dripping density and the preset reference density, the product value between the quotient and the adjusted oil dripping amount is calculated as the new adjusted oil dripping amount. The reference density refers to the density of the oil used in the reference setting of the oil dripping device, which is preset and stored by the operator.

[0199] Step S502: determining the oil dripping height according to the liquid information and the updated adjusted oil dripping amount.

[0200] The oil dripping height refers to the height at which the oil dripping device drips oil. The oil dripping height is matched from the oil dripping database through the liquid information and the updated adjusted oil dripping amount.

[0201] Step S503: Obtain the rising direction and rising speed of the steam in the preset heating container.

[0202] The steam rising direction refers to the rising direction of the steam generated when the pot still distills liquid. The steam rising speed refers to the speed at which the steam generated when the pot still distills liquid. The wind speed and direction sensor preset on the pot still detects the obtained parameter as the steam rising speed, and the steam rising direction is determined by the positive and negative conditions of the parameter.

[0203] Step S504: Update the steam rising direction according to the marked foam position, the preset distillation internal shape and the preset liquid center position.

[0204] The internal shape of the distillation refers to the shape of the interior of the pot still for placing and distilling the liquid. The operator pre-queries the internal dimensions corresponding to the specifications of the pot still to obtain the internal shape of the distillation. The straight-line distance between the center positions of the liquids is calculated by marking the foam position, and the correction vector distance is matched from the preset correction database through the internal shape of the distillation and the straight-line distance. The direction parameter obtained after the marked foam position is offset by the correction vector distance is used as the new steam rising direction. The correction database stores the correction vector distances corresponding to the offset distances of different internal shapes of the distillation and the marked foam position on the center position of the liquid, and also stores the correction values ​​of the oil drip heights corresponding to different steam rising speeds. The correction database is set manually and will not be described in detail here.

[0205] Step S505: Update the oil dripping height according to the steam rising speed.

[0206] The corresponding correction value is matched from the correction database through the steam rising speed, and the product value between the oil dripping height and the correction value is calculated and used as the new oil dripping height.

[0207] Step S506: determining the oil dripping position according to the updated steam rising direction and the updated oil dripping height.

[0208] The oil dripping position refers to the position where the oil dripping device drips oil. The lateral position point is obtained by marking the foam position and offsetting it laterally with the updated steam rising direction. The position parameter obtained after vertical offsetting the lateral position point with the updated oil dripping height is used as the oil dripping position.

[0209] Step S507: adding the oil dripping control parameter according to the oil dripping position to update the oil dripping control parameter, and outputting the updated oil dripping control parameter to the oil dripping device.

[0210] By adding the oil dripping position to the oil dripping control parameter to form a new oil dripping control parameter, and outputting the oil dripping control parameter to the oil dripping device, the oil dripping device is not prone to data deviation in the oil dripping position under the influence of steam.

[0211] The invention also includes the specific steps after outputting the updated oil dripping control parameters to the oil dripping device:

[0212] Step S600: When the center position of the liquid does not fall into the foam coverage area corresponding to the marked foam circle center, a reference viscosity value of the oil corresponding to the oil drop density is obtained.

[0213] The reference viscosity value refers to the viscosity of the oil corresponding to the total amount of oil dripping. When the center position of the liquid falls into the foam coverage range corresponding to the center of the marked foam circle, it means that the oil diffusion range corresponding to the oil dripping device dripping covers the center position of the liquid, and the oil dripping control parameters continue to be output. When the center position of the liquid does not fall into the foam coverage range corresponding to the center of the marked foam circle, it means that the oil diffusion range corresponding to the oil dripping device dripping is not the center position of the liquid, then the information of the oil used is matched from the preset oil dripping database through the liquid information and the reference temperature value, and the viscosity value of the oil is retrieved from the oil information as the reference viscosity value.

[0214] Step S601: Retrieve the liquid viscosity value according to the liquid information.

[0215] The liquid viscosity value refers to the viscosity value corresponding to the liquid information, and the viscosity value of the liquid is retrieved from the liquid information as the liquid viscosity value.

[0216] Step S602: When the reference viscosity value is greater than the liquid viscosity value, the corresponding straight line distance is calculated according to the marked foam circle center and the liquid center position and used as the reference offset distance.

[0217] The reference offset distance refers to the straight-line distance between the center of the marked foam circle and the center position of the liquid. When the reference viscosity value is not greater than the liquid viscosity value, it means that the oil diffusion range is not greater than the foam coverage range, and the oil drip control parameters continue to be output. When the reference viscosity value is greater than the liquid viscosity value, it means that the oil diffusion range is greater than the foam coverage range, and the straight-line distance between each marked foam circle center and the liquid center position is calculated as the reference offset distance.

[0218] Step S603: Arrange in reverse order based on the reference offset distance, and select the marked foam circle center corresponding to the smallest reference offset distance as the priority oil dripping circle center.

[0219] The priority oil dripping center refers to the marked foam center for priority oil dripping, which is arranged from small to large by various reference offset distances, and the marked foam center corresponding to the smallest reference offset distance is selected as the priority oil dripping center.

[0220] Step S604: determining a priority diffusion range according to the liquid viscosity value, the oil drop height corresponding to the priority oil drop circle center, and adjusting the oil drop amount.

[0221] The priority diffusion range refers to the diffusion range of the oil after oil is dripped from the priority oil dripping circle center. The diffusion range corresponding to the priority oil dripping circle center is calculated from the calculation database through the liquid viscosity value, the oil dripping height corresponding to the priority oil dripping circle center and the adjusted oil dripping amount as the priority diffusion range.

[0222] Step S605: When the reference offset distance of the center of the priority oil dripping circle falls within the diffusion range, the oil dripping adjustment sequence is determined according to the reference offset distances arranged in reverse order.

[0223] The oil drip adjustment sequence refers to the oil drip sequence after adjustment. When the reference offset distance of the priority oil drip center does not fall within the diffusion range, it means that the oil drip device cannot suppress the generation of foam in the process of reducing foam, and the oil drip control parameters continue to be output. When the reference offset distance of the priority oil drip center falls within the diffusion range, it means that the oil drip device can suppress the generation of foam in the process of reducing foam, and the order of oil dripping at the marked foam positions corresponding to the reference offset distances from small to large is used as the oil drip adjustment sequence.

[0224] Step S606: replacing the oil dripping sequence in the oil dripping control parameter according to the oil dripping adjustment sequence to form a new oil dripping control parameter, and outputting the new oil dripping control parameter to the oil dripping device.

[0225] By replacing the oil dropping sequence in the oil dropping control parameter with the oil dropping adjustment sequence to form a new oil dropping control parameter, and outputting the new oil dropping control parameter to the oil dropping device, the oil can be dropped from the center of the liquid to the outside. After the oil diffuses, the center of the liquid can be covered, thereby reducing the foam and preventing the liquid from re-generating foam.

[0226] The step of outputting the new oil dripping control parameters to the oil dripping device is also included, which is as follows:

[0227] Step S700: Determine the oil dripping time according to the updated oil dripping height.

[0228] The oil dripping time refers to the time interval between oil dripping by the oil dripping device at the updated oil dripping height. The oil dripping time is matched from the oil dripping database through the updated oil dripping height.

[0229] Step S701: Determine the liquid distillation amount per unit time according to the reference temperature value and liquid information.

[0230] The liquid distillation volume refers to the amount of liquid reduced after distillation. The liquid distillation volume per unit time is matched from the preset distillation database through the reference temperature value and liquid information. The distillation database stores the liquid distillation volume per unit time corresponding to different reference temperature values ​​and liquid information, and also stores the maximum total amount of oil dripping corresponding to the liquid volume in different pot stills and the type of oil, as well as the amount of liquid in the pot still corresponding to the deviation value of different oils. The distillation database is set manually and will not be described in detail here.

[0231] Step S702: Calculate the product of the oil dripping time and the liquid distillation amount and use it as the total liquid distillation amount.

[0232] The total amount of liquid distillation refers to the total amount of liquid reduced after distillation during the dripping time. The product of the dripping time and the liquid distillation amount is calculated and used as the total amount of liquid distillation.

[0233] Step S703: Calculate the difference between the total amount of liquid distillation and the preset reference liquid amount and use it as the remaining distillation amount.

[0234] The remaining distillation volume refers to the total amount of liquid remaining in the pot still after the liquid is distilled during the dripping time. The difference between the total amount of liquid distillation and the preset reference liquid volume is calculated and used as the remaining distillation volume. The reference liquid volume refers to the amount of liquid in the pot still after initial fermentation, which is set and stored by the operator in advance.

[0235] Step S704: determining the oil drop information according to the oil drop density.

[0236] The oil dripping information refers to the type of oil used in the oil dripping device. The corresponding oil type information is queried from the network through the oil dripping density as the oil dripping information.

[0237] Step S705: Determine the maximum total amount of oil dripping according to the remaining distillation amount and the oil dripping information.

[0238] The maximum total amount of oil dripping refers to the maximum value of the remaining distillation volume that can drip oil. The maximum total amount of oil dripping is matched from the distillation database by the remaining distillation volume and the oil dripping information.

[0239] Step S706: Calculate the difference between the maximum total amount of oil dripping and the updated total amount of oil dripping and use it as the oil amount deviation value.

[0240] The oil quantity deviation value refers to the deviation value between the maximum total amount of oil dripping and the updated total amount of oil dripping. The difference between the maximum total amount of oil dripping and the updated total amount of oil dripping is calculated and used as the oil quantity deviation value.

[0241] Step S707: when the oil volume deviation value does not fall within the preset reference deviation range, determining the liquid increase amount according to the oil volume deviation value.

[0242] The benchmark deviation range refers to the deviation range of the oil corresponding to the liquid that does not need to be added in the pot still, and is formed by pre-setting and storage by the operator. The amount of liquid increase refers to the liquid that needs to be added in the pot still. When the oil amount deviation value falls into the benchmark deviation range, it means that there is no need to increase the liquid in the pot still, and no adjustment is made. When the oil amount deviation value does not fall into the benchmark deviation range, it means that the liquid in the pot still needs to be increased, and the amount of liquid increase is matched from the distillation database through the oil amount deviation value.

[0243] Step S708: determining a preheating temperature value according to a reference temperature value.

[0244] The preheating temperature value refers to the temperature value of the liquid preheated corresponding to the amount of liquid increase. The preheating temperature value is matched from the preset temperature database through the reference temperature value. The temperature database stores the preheating temperature values ​​corresponding to different reference temperature values, and also stores the oil dripping height corresponding to different heating times. The temperature database is set manually and will not be described in detail here.

[0245] Step S709: controlling the preset preheating device to preheat at a preheating temperature value according to the increased amount of liquid, and delivering the preheated increased amount of liquid to the heating container.

[0246] The preheating device refers to a device that is pre-installed on the pot still and is used to preheat the liquid corresponding to the increased amount of liquid. The preheating device can be a container equipped with a semiconductor heating plate, and the preheating device is connected to the pot still through a pipeline. The preheating device is controlled to preheat the liquid corresponding to the increased amount of liquid at a preheating temperature value, and the preheated increased amount of liquid is transported to the heating container, so that the pot still can continue to distill after the liquid is added.

[0247] Step S710: Calculate the difference between the preheating temperature value and the reference temperature value and use it as the temperature deviation value.

[0248] The temperature deviation value refers to the deviation value between the preheating temperature value and the reference temperature value. The difference between the preheating temperature value and the reference temperature value is calculated and used as the temperature deviation value.

[0249] Step S711: Calculate the quotient of the temperature deviation value and the heating temperature and use it as the heating time.

[0250] Heating time refers to the time required to heat the liquid corresponding to the increased amount of liquid to the reference temperature value. The quotient of the temperature deviation value and the heating temperature is calculated as the heating time.

[0251] Step S712: updating the adjustment time according to the heating time, and adding the updated adjustment time to the oil dripping control parameter to form a new oil dripping control parameter and output it to the oil dripping device.

[0252] By using the parameter corresponding to the heating time as the new adjustment time, and adding the updated adjustment time to the oil dripping control parameter to form a new oil dripping control parameter and outputting it to the oil dripping device, it is not easy for the steam amount to decrease when heating the liquid to cause oil dripping data deviation.
