[0066] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0067] See also Figure 1 , is a schematic flow chart of a method for drying nuts provided by an embodiment of the present invention, Figure 1 The execution subject of the method shown may be a software and / or hardware device. The execution subject of the present application may include but is not limited to at least one of the following: user equipment, network equipment, etc. Among them, the user equipment may include but is not limited to computers, smart phones, personal digital assistants (Personal Digital Assistant, referred to as: PDA) and the electronic devices mentioned above. The network equipment may include but is not limited to a single network server, a server group consisting of multiple network servers, or a cloud based on cloud computing consisting of a large number of computers or network servers, wherein cloud computing is a type of distributed computing, a super virtual computer composed of a group of loosely coupled computers. This embodiment does not limit this. It includes steps S1 to S4, as follows:

[0068] S1, obtaining a captured image of nuts to be screened based on a capture device in a screening area, and determining the nuts to be screened that meet a drying reference condition as a reference nut group according to nut image data corresponding to the captured image.

[0069] Among them, the screening area refers to an area where nuts for drying reference can be screened, and images of nuts can be taken in the screening area. The acquisition device refers to a device that can take images, such as a camera. The nuts to be screened refer to the nuts in the screening area. The acquired image refers to the image obtained by photographing the nuts to be screened. The nut image data refers to the image data corresponding to the nuts to be screened in the acquired image. The drying reference condition refers to the condition that the shape of the nuts selected for drying reference is regular and the total weight is within a pre-configured weight range. The reference nut group refers to a reference group composed of multiple nuts to be screened that meet the drying reference condition.

[0070] In the processing of nuts, ensuring that the nuts are dried to an appropriate degree is a key step to improve product quality, taste and extend shelf life. In order to achieve more accurate and efficient drying, this solution can monitor the drying process of nuts and adjust the relevant parameters of drying accordingly based on the monitoring data during the drying process. This can accurately control the moisture content of nuts, avoid the deterioration of nut quality caused by insufficient drying, reduce unnecessary drying time and improve the efficiency of drying.

[0071] It is understandable that when monitoring the nut drying process, since nuts in the same batch usually have high similarity in drying characteristics, in order to reduce the workload of data processing and improve data processing efficiency, this solution does not monitor every nut in detail, but selects representative nuts with relatively regular shapes in the same batch as samples, monitors their drying conditions, and combines the monitoring results of the samples to make a more accurate prediction of the drying conditions of the entire batch of nuts, and can make corresponding adjustments to the drying parameters based on the monitoring data of the sample nuts.

[0072] Specifically, before drying the nuts, a specific area can be set up, which can be used to select nuts for drying reference. The area can be determined as a screening area. In actual operation, the same batch of nuts can be carefully divided into multiple groups, and each group is assigned a dedicated tray to neatly place the corresponding nuts. The user can flexibly select a group of nuts from multiple groups and move them to the screening area. In the screening area, representative samples can be selected from the selected nut group. These samples can be used as monitoring objects during the drying process to ensure that the effect of the entire drying process meets the user's expected standards.

[0073] In order to automatically screen the nuts in the screening area, a collection device capable of taking images of the nuts, such as a camera, can be arranged above the screening area. The collection device can be controlled to take images of all the nuts to be screened in the screening area, and a corresponding collection image can be obtained. In the collection image, there are image data corresponding to multiple nuts to be screened. According to the corresponding multiple nut image data, it can be determined whether the nuts to be screened in the screening area meet the drying reference conditions. If the drying reference conditions are met, the corresponding nuts to be screened can be screened out as samples for monitoring, so that the corresponding reference nut group can be obtained.

[0074] In some embodiments, the specific implementation of step S1 may be:

[0075] S11, extracting a plurality of nut contours from the collected image, wherein the nut image data includes the nut contours.

[0076] It is understandable that in order to obtain more accurate monitoring data, when determining the reference nut group, the nuts in the screening area can first be screened according to their appearance to select nuts with more regular shapes. Nuts with more regular shapes have a more uniform drying effect during drying. Therefore, monitoring the drying conditions of nuts with more regular shapes can improve the accuracy of obtaining monitoring data.

[0077] Specifically, when performing a screening based on the appearance, contour extraction technology such as edge detection algorithm can be used to extract contours corresponding to multiple nuts to be screened, i.e., nut contours, from the captured image, and corresponding screening can be performed based on the differences between the contours. The nut contour refers to the contour corresponding to the nut to be screened.

[0078] S12, obtaining the appearance similarity between each nut outline and a standard nut outline based on an appearance similarity calculation model, and determining the nut outline whose appearance similarity is greater than or equal to an appearance similarity threshold as a screening outline.

[0079] Among them, the appearance similarity calculation model refers to a model that can calculate the similarity between nut contours, the standard nut contour refers to the regular contour corresponding to the pre-configured standard nut size, the appearance similarity refers to the degree of similarity between the nut contour and the standard nut contour, the appearance similarity threshold refers to the pre-set similarity threshold that can be used to measure whether the shape of the nut is regular, if the appearance similarity is greater than or equal to the appearance similarity threshold, it can be considered that the shape of the nut corresponding to the nut contour is relatively regular, and the corresponding nut contour can be used as a screening contour, if the appearance similarity is less than the appearance similarity threshold, it can be considered that the shape of the nut corresponding to the nut contour is irregular, and the screening contour refers to the nut contour whose appearance similarity is greater than or equal to the appearance similarity threshold.

[0080] Specifically, a pre-trained shape similarity calculation model can be retrieved, and the shape similarity between each nut outline and the standard nut outline can be obtained by inputting the nut outline of each nut to be screened and the standard nut outline into the shape similarity calculation model. When the shape similarity is greater than or equal to the shape similarity threshold, it can be considered that the corresponding nut outline is almost the same as the standard nut outline and is relatively regular. At this time, the corresponding nut outline can be determined as the screening outline, see Figure 2 , which is a schematic diagram of determining a screening profile provided by an embodiment of the present invention, such as Figure 2As shown in , by comparing the contours of each nut in the captured image with the standard nut contour, it is obvious that nut contour 1 is almost consistent with the standard nut contour and is relatively regular. Nut contour 1 can be determined as the screening contour. The difference between nut contour 2 and the standard nut contour is large, and nut contour 2 cannot be determined as the screening contour. By determining the screening contour, it can be ensured that the nuts corresponding to the reference nut group have very small differences in appearance, which can reduce errors when obtaining monitoring data later.

[0081] S13, obtaining the mean value of the contour area of ​​each screening contour, calculating the contour area difference between the contour area of ​​each screening contour and the mean value of the contour area, and arranging the nuts to be screened corresponding to each screening contour from small to large according to the contour area difference to obtain a screening sequence.

[0082] After obtaining multiple screening contours, the contour areas corresponding to the multiple screening contours can be averaged to obtain the corresponding contour area averages, and the contour area averages can be used as the basis for subsequent comparison and sorting. According to the contour areas corresponding to the various screening contours, the difference between the contour areas of the various screening contours and the contour area averages can be calculated, that is, the contour area difference. The contour area difference can intuitively reflect the degree of deviation of the area of ​​each screening contour from the overall average. According to the size of the contour area difference, the nuts to be screened corresponding to the various screening contours are arranged to obtain a screening sequence, through which nuts that meet the requirements can be selected more accurately.

[0083] Among them, the mean contour area refers to the average value of the contour areas corresponding to multiple screening contours, the contour area difference refers to the difference between the contour area of ​​the screening contour and the mean contour area, and the screening sequence refers to the sequence obtained by arranging the nuts to be screened.

[0084] S14, according to the screening sequence statistics, the total nut weight of the corresponding nuts to be screened is counted in sequence, it is determined that the nuts to be screened whose total nut weight is within the reference weight range meet the drying reference condition, and the corresponding nuts to be screened are obtained as a reference nut group.

[0085] After obtaining the screening sequence, in order to make a more accurate prediction of the drying conditions of other nut groups in the same batch based on the monitoring data of the screened nuts, the nuts to be screened in the screening sequence can be screened for the second time according to their weight, so that the corresponding reference nut group can be obtained. In order to ensure the accuracy of the subsequent acquisition of drying reference data, the weight of the nuts to be screened can be counted in sequence according to the screening sequence to obtain the corresponding total nut weight.

[0086] In order to obtain a reference nut group with a weight that is relatively consistent with other groups and improve the accuracy of obtaining monitoring data, the present scheme can pre-configure a weight range interval, and the weight of other nut groups is within this range interval, and this range interval can be determined as a reference weight interval. When the total nut weight is within the reference weight interval, it can be considered that the total weight of the corresponding nuts to be screened is almost consistent with the weight of other nut groups, and the corresponding nuts to be screened meet the drying reference conditions. Therefore, the corresponding nuts to be screened can be determined as the reference nut group. By monitoring the drying condition of the reference nut group, it is convenient to make corresponding adjustments to the drying parameters of nuts of other groups based on the monitoring data of the reference nut group.

[0087] Among them, the total nut weight refers to the total weight of the nuts to be screened selected for drying reference, the reference weight range refers to a pre-configured range range, and the weight of the reference nut group and the weights of other nut groups are within the reference weight range.

[0088] Through the above implementation, it can be ensured that the reference nut group has a high degree of similarity and can more accurately reflect the drying conditions of nuts in the same batch.

[0089] In some embodiments, the step S14 of "counting the total nut weights of the nuts to be screened in sequence according to the screening sequence statistics, and determining that the nuts to be screened whose total nut weights are within the reference weight range meet the drying reference conditions" includes the following steps:

[0090] S141, obtaining the first nut to be screened in the screening sequence as a reference nut, and obtaining the nut weight of the reference nut based on a weighing device in the screening area.

[0091] Specifically, when obtaining the total weight of nuts, if the weight of each nut to be screened in the screening sequence is obtained in turn, the efficiency is low. In order to reduce the amount of data processing and improve data processing efficiency, the first nut to be screened can be selected from the screening sequence as a reference nut, and the weight of other nuts to be screened can be predicted based on the difference between the area of ​​the reference nut and other nuts. When obtaining the weight of the reference nut, a weighing device capable of obtaining the weight can be configured in the screening area, such as a pressure sensor. The automatic control device, such as a robotic arm, places the selected reference nut on the weighing device. The weight of the reference nut can be obtained through the weighing device, and the weight of the reference nut can be used as a reference weight to predict the weight of other nuts.

[0092] Among them, the reference nuts refer to the nuts to be screened that can predict the weight of other nuts to be screened, the weighing device refers to the device that can obtain the weight of the reference nuts, such as a pressure sensor, and the nut weight refers to the weight of the reference nuts.

[0093] S142, determining the sub-area difference between the screening profile of the first nut to be screened in the screening sequence and the screening profiles of the remaining nuts to be screened, and obtaining a weight adjustment coefficient according to a ratio of the sub-area difference to a reference weighing area difference.

[0094] Specifically, the area difference between the contour area of ​​the screening contour of the first nut to be screened in the screening sequence and the screening contours of the remaining nuts to be screened, that is, the sub-area difference, can be obtained. By calculating the ratio of the sub-area difference to the pre-configured benchmark weighing area difference, the corresponding weight adjustment coefficient can be obtained, and the weight of other nuts can be predicted based on the weight adjustment coefficient.

[0095] Among them, the sub-area difference refers to the difference between the area of ​​the screening contour corresponding to the first nut to be screened and the contour area of ​​the remaining nuts to be screened, the weighing area difference refers to the pre-configured benchmark area difference, and the weight adjustment coefficient refers to the coefficient that can predict the weight of the remaining nuts to be screened.

[0096] S143, multiplying the weight adjustment coefficient and the nut weight of the reference nut to obtain the predicted weight of the remaining nuts to be screened.

[0097] After obtaining the weight adjustment coefficients corresponding to the remaining nuts to be screened in the screening sequence, the weight adjustment coefficients can be multiplied by the weight of the reference nut to obtain the predicted weights corresponding to the remaining nuts to be screened in the screening sequence. The predicted weight refers to the weights predicted for the remaining nuts to be screened based on the weight of the reference nut.

[0098] S144, based on the screening sequence, the predicted weight of each nut to be screened and the nut weight of the reference nuts are statistically analyzed in turn to obtain the total nut weight, the nut to be screened whose total nut weight is within the reference weight range is determined as the reference nut, and the reference nut is determined to meet the drying reference condition.

[0099] Specifically, after obtaining the predicted weight corresponding to each nut to be screened, the predicted weight of each nut to be screened and the nut weight of the reference nuts can be added in sequence according to the screening sequence to obtain the corresponding total nut weight. If the total nut weight is within the reference weight range, the corresponding multiple nuts to be screened can be determined as reference nuts, and it can be determined that the corresponding multiple reference nuts meet the drying reference conditions.

[0100] Based on the above embodiment, the specific implementation of step S144 may be:

[0101] S1441, continue to determine the next nut to be screened in the screening sequence as a determined nut, and perform statistics on the predicted weight of the determined nut and the nut weight to obtain a total nut weight.

[0102] Specifically, after obtaining the predicted weight of each nut to be screened in the screening sequence, the next nut to be screened after the reference nut in the screening sequence can be determined as the judgment nut, and the predicted weight of the judgment nut is added to the nut weight of the reference nut to obtain the corresponding total nut weight.

[0103] S1442: When the total nut weight is less than the minimum value of the reference weight interval, determine that the determined nut is the next reference nut.

[0104] When the total nut weight is less than the minimum value of the reference weight range, it can be considered that the sum of the weight of the determined nuts and the weight of the reference nuts is insufficient to meet the drying reference conditions, and it is necessary to continue to add nuts to increase the total weight. At this time, the corresponding determined nuts can be determined as the next reference nuts. When the total nut weight is obtained later, the weights of all the reference nuts need to be counted.

[0105] S1443, continue to obtain the next determination nut, repeat the above step of determining the reference nut, and stop obtaining the reference nut until the total nut weight is within the reference weight range.

[0106] Specifically, continue to use the newly determined reference nut as a benchmark, determine the next nut to be screened as the next judgment nut, add the weight of the judgment nut to the nut weight of all the reference nuts determined previously, and get a new total nut weight. If the newly acquired total nut weight is still less than the minimum value of the reference weight interval, then the next judgment nut can also be determined as a reference nut, and then use the reference nut as a benchmark to obtain the next judgment nut, and calculate its total nut weight with all the reference nuts, and determine whether the newly acquired total nut weight is within the reference weight interval. Repeat the step of determining the reference nut until the acquired total nut weight is within the reference weight interval, and then stop the step of obtaining the reference nut.

[0107] S1444, when the total nut weight is greater than the maximum value of the reference weight interval, a first weight difference is obtained according to the difference between the current total nut weight and the maximum value, and a second weight difference between the minimum value of the reference weight interval and the previous total nut weight is obtained.

[0108] In practical applications, each time a reference nut is determined, the total reference weight can be obtained, but the total nut weight obtained may be greater than the maximum value of the reference weight range. At this time, by comparing the weight difference before and after adding the last nut, the reference nut group corresponding to the total reference weight with the smallest difference from the reference weight range can be found, thereby achieving weight control while minimizing the error as much as possible.

[0109] Specifically, the difference between the current total nut weight and the maximum value of the reference weight interval can be obtained and determined as the first weight difference, and the difference between the total reference weight before the last reference nut was determined and the minimum value of the reference weight interval can be obtained and determined as the second weight difference. By comparing the first weight difference with the second weight difference, the total reference weight with the smallest difference from the reference weight interval can be obtained, which can reduce the error when the drying parameters are adjusted later.

[0110] S1445, if the first weight difference is smaller than the second weight difference, the determined nut is determined to be the last reference nut; if the first weight difference is greater than the second weight difference, the previous reference nut is determined to be the last reference nut.

[0111] If the first weight difference is smaller than the second weight difference, it can be considered that the difference between the current total nut weight and the reference weight interval is the smallest, so the corresponding determined nut can be retained as the last reference nut. If the first weight difference is greater than the second weight difference, it can be considered that the difference between the previous total nut weight and the reference weight interval is the smallest. At this time, the corresponding determined nut can be removed and the previous reference nut can be determined as the last reference nut.

[0112] See also Figure 3 , is a schematic diagram of a screening sequence provided by an embodiment of the present invention, such as Figure 3 As shown in , the weights of the nuts to be screened in the screening sequence increase from left to right. The current total nut weight is the total weight of reference nut 1, reference nut 2 and the determined nut. The previous total nut weight is the total weight of reference nut 1 and reference nut 2. When the first weight difference is less than the second weight difference, the determined nut can be retained as the last reference nut. When the first weight difference is greater than the second weight difference, the determined nut can be removed and reference nut 2 can be used as the last reference nut.

[0113] Through the above implementation, it is possible to control the weight while reducing the error as much as possible and improving the accuracy of data acquisition.

[0114] S2, controlling the transport device to place the reference nut group in the detection area of ​​the drying device, and placing the nut group to be baked from the same batch as the reference nut group in the drying area of ​​the drying device.

[0115] Among them, the transporting equipment refers to equipment that can transport the nut group to the corresponding area, such as an intelligent robot, and the drying equipment refers to equipment that can dry the nuts, such as a hot air circulation baking oven. The drying equipment contains a detection area for monitoring the drying conditions and a drying area for drying the remaining nut groups. The detection area refers to the area for monitoring the drying conditions of the reference nut group, and the drying area refers to the area for drying the nut group to be baked.

[0116] After obtaining the reference nut group, other nuts from the same batch as the reference nut group can be identified as the nut group to be baked, and the corresponding weight of each nut group to be baked is within the reference weight range, so that the drying condition of the nut group to be baked can be more accurately predicted based on the drying condition of the reference nut group. Then, the conveying equipment can be controlled to place the reference nut group in the detection area of ​​the drying equipment, and the nut group to be baked in the drying area of ​​the drying equipment. Subsequently, the drying condition of the nuts in the detection area can be monitored, and the drying condition of the nut group to be baked in the drying area can be inferred based on the monitoring data.

[0117] S3, obtaining measurement change data of the detection area, and determining drying parameters of the drying equipment according to the measurement change data.

[0118] In practical applications, during the drying process, corresponding measurement change data can be obtained from the detection area. Since the drying process is essentially a process of gradually reducing the moisture content of the nuts, there is a close correlation between the weight of the nuts and their moisture content. According to the change in the weight of the nuts, the corresponding change in moisture content can be indirectly inferred. After obtaining the measurement change data, the corresponding drying parameters can be determined by analyzing the measurement change data, and the drying parameters can be adjusted accordingly based on the actual drying conditions of the nuts.

[0119] The measured change data refers to the weight change data of the nuts obtained from the detection area during the drying process, and the drying parameters refer to the drying time, drying temperature and other parameters corresponding to the drying equipment.

[0120] In some embodiments, the specific implementation of step S3 may be:

[0121] S31, counting the initial nut weight of the reference nut group in the detection area, and determining the initial moisture content corresponding to the initial nut weight.

[0122] In actual applications, a pressure sensor capable of measuring weight can be configured in the detection area of ​​the drying equipment. The weight corresponding to the reference nut group in the detection area, that is, the initial nut weight, can be obtained through the pressure sensor. Since the weight of the nuts is closely related to the water content, the larger the weight, the higher the corresponding water content. Therefore, based on the initial nut weight, the corresponding water content, that is, the initial water content, can be determined. This scheme can use an instrument for measuring the moisture content of foods such as nuts, such as a nut moisture meter, to determine the initial moisture content of the reference nut group.

[0123] Among them, the initial nut weight refers to the weight corresponding to the reference nut group in the detection area that has not been dried, and the initial moisture content refers to the moisture content corresponding to the initial nut weight.

[0124] S32, obtaining the target moisture content input by the user, and determining the target nut weight corresponding to the target moisture content.

[0125] Specifically, the user can input the expected moisture content of the nuts through the user terminal, that is, the moisture content desired to be achieved after drying, and the corresponding moisture content can be determined as the target moisture content. According to the initial moisture content and the target moisture content, the change in moisture content can be determined. Since the drying process is essentially a process of gradually reducing the moisture content of the nuts, the weight will decrease accordingly as the moisture content decreases. Therefore, the change in moisture content can be inferred based on the weight change of the nuts. According to the initial weight of the nuts and their corresponding weight change, the weight that the nuts should reach after drying, that is, the target nut weight, can be calculated.

[0126] Among them, the target moisture content refers to the moisture content that the user expects to achieve after drying, and the target nut weight refers to the weight of the nuts corresponding to the target moisture content when the nuts are dried to the target moisture content.

[0127] S33, retrieving historical drying data of multiple dried nuts of the same type as the nuts to be screened, and determining the predicted time corresponding to the target nut weight according to the historical drying data.

[0128] In practical applications, the time required for the drying process of the nuts can be determined based on the weight change data of the nuts during the drying process. Specifically, nuts of the same type as the nuts to be screened can be divided into multiple batches for drying. The drying time for each batch is different. Therefore, the historical drying data of multiple dried nuts of exactly the same type as the nuts to be screened can be retrieved. These data usually include the weight change data of the nuts during the drying process and the corresponding drying time. Using the historical drying data, combined with the initial weight of the nuts to be screened, the time required to dry them to the target nut weight can be predicted.

[0129] Among them, dried nuts refer to nuts that have been dried, historical drying data refers to data corresponding to the drying process of the dried nuts, including weight change data and drying time data, and predicted time refers to the time required to dry the nuts to the target weight predicted based on historical drying data.

[0130] In some embodiments, step S33 includes S331 to S334, which are specifically as follows:

[0131] S331, obtaining the historical drying time of each of the dried nuts, and calculating the average drying time of each of the historical drying times.

[0132] Specifically, the drying time corresponding to each dried nut, that is, the historical drying time, can be obtained, and the average drying time can be obtained by averaging multiple historical drying times. The historical drying time refers to the drying time corresponding to the dried nuts, and the average drying time refers to the average value corresponding to multiple historical drying times.

[0133] S332, determining the historical initial weight and the historical target weight of each of the dried nuts, obtaining the historical change difference between the historical initial weight and the historical target weight, and calculating the average change difference of each of the historical change differences.

[0134] In actual applications, based on the historical drying data corresponding to the dried nuts, the initial weight of the dried nuts before drying, that is, the historical initial weight, can be obtained, and the weight of the dried nuts after drying, that is, the historical target weight, can also be obtained. Based on the historical initial weight and historical target weight corresponding to each dried nut, the difference between the two, that is, the historical change difference, can be obtained. By averaging multiple historical change differences, the corresponding average change difference can be obtained.

[0135] Among them, the historical initial weight refers to the weight of the dried nuts before drying, the historical target weight refers to the weight of the dried nuts after drying, the historical change difference refers to the difference between the historical initial weight and the historical target weight, and the average change mean refers to the average value corresponding to multiple historical change differences.

[0136] S333, obtaining the current change difference between the initial nut weight and the target nut weight, and calculating the difference between the current change difference and the average change difference.

[0137] In practical applications, the drying time required for the reference nut group can be inferred based on the corresponding weight changes of the reference nut group. Specifically, the difference between the initial nut weight and the target nut weight, that is, the current change difference, can be obtained, and the difference between the current change difference and the average change difference can be calculated. The difference value can reflect the degree of deviation between the current data and historical data of the reference nut group. Subsequently, the predicted time corresponding to the reference nut group can be determined based on the difference value.

[0138] Among them, the current change difference refers to the difference between the initial nut weight corresponding to the reference nut group and the target nut weight, and the difference value refers to the difference between the current change difference and the average change difference.

[0139] S334, obtaining a difference ratio according to the ratio of the difference value to the benchmark difference value, obtaining an adjustment coefficient based on the product of the difference ratio and the difference weight, and obtaining a predicted duration corresponding to the target nut weight according to the product of the adjustment coefficient and the average change difference.

[0140] Specifically, the corresponding difference ratio can be obtained by calculating the ratio of the difference value to a pre-configured benchmark difference value, and the difference weight that can be used to adjust the difference ratio is retrieved. By multiplying the difference ratio with the difference weight, the difference ratio can be appropriately adjusted to obtain the corresponding adjustment coefficient. By multiplying the adjustment coefficient with the average change difference, the average change difference can be adjusted accordingly to obtain the predicted time corresponding to the target nut weight, thereby more accurately predicting the drying time required for the current nut group.

[0141] Among them, the benchmark difference value refers to a pre-set standard value, which can be used to evaluate the size of the difference value. The difference ratio refers to the value obtained by calculating the ratio of the difference value to the standard difference value, which can reflect the relative deviation of the difference value corresponding to the reference nut group from the standard value. The difference weight refers to the value that can be used to adjust the difference ratio. The adjustment coefficient refers to the coefficient obtained after adjusting the difference ratio by the difference weight.

[0142] Through the above implementation, the time required for drying the current nut group to the target weight can be predicted more accurately.

[0143] S34, obtaining the changed nut weight of the reference nut group in the detection area according to the predicted duration, and updating the predicted duration to obtain the changed duration based on a comparison result between the changed nut weight and the target nut weight.

[0144] The measured change data include the initial nut weight and the changed nut weight, and the drying parameters include the predicted duration and the changed duration.

[0145] Specifically, after obtaining the predicted duration, the reference nut group is dried according to the predicted duration, and the weight change during the drying process is measured to obtain the corresponding weight of the reference nut group after drying, that is, the changed nut weight. The changed nut weight after drying is compared with the target nut weight. If the reference nut group is dried within the predicted duration and still does not reach the target nut weight desired by the user, it can be considered that the predicted duration may be insufficient, and the predicted duration needs to be adjusted and updated accordingly to obtain the corresponding changed duration, thereby more accurately reflecting the actual drying needs and ensuring that the nuts can be dried to the target weight within an appropriate duration.

[0146] The changed nut weight refers to the weight after drying corresponding to the reference nut group, and the changed duration refers to the duration obtained after adjusting and updating the predicted duration.

[0147] Through the above implementation, accurate control of the drying process can be achieved and the drying efficiency can be improved.

[0148] In some embodiments, the specific implementation of step S34 may be:

[0149] S341, obtaining the initial drying time and the current drying time of the drying device, and obtaining the current drying time according to the time interval between the initial drying time and the current drying time.

[0150] Specifically, during the drying process, the moment when the drying equipment starts the drying operation, i.e., the initial drying moment, and the current corresponding moment, i.e., the current drying moment, can be obtained. According to the time interval between the initial drying moment and the current drying moment, the corresponding current drying time can be obtained. The current drying time can reflect the time that the drying process has lasted.

[0151] The initial drying time refers to the time point at which the drying process starts, the current drying time refers to the current time point, and the current drying time refers to the time interval between the initial drying time and the current drying time.

[0152] S342: When the current drying time is equal to the predicted time, obtain the current changed nut weight of the reference nut group.

[0153] Specifically, when the current drying time is equal to the predicted time, it can be considered that the drying process is completed according to the predicted time. At this time, the weight corresponding to the reference nut group can be measured to obtain the changed nut weight corresponding to the reference nut group.

[0154] S343, comparing the changed nut weight with the target nut weight, and when the changed nut weight is greater than the target nut weight, obtaining the weight difference between the changed nut weight and the target nut weight.

[0155] Specifically, by comparing the changed nut weight with the target nut weight, if the changed nut weight is greater than the target nut weight, it can be considered that the moisture content of the nuts has not reached the target moisture content expected by the user, and the drying time needs to be adjusted. At this time, the weight difference between the changed nut weight and the target nut weight can be calculated, and the predicted time can be subsequently updated accordingly based on the weight difference.

[0156] The weight difference refers to the difference between the weight of the changed nuts and the target nut weight.

[0157] S344: When the weight difference is greater than or equal to a weight difference threshold, obtain an offset difference between the weight difference and the weight difference threshold.

[0158] Among them, the weight difference threshold refers to a preset threshold, which can be used to determine the deviation between the weight of the dried nuts and the target weight. If the weight difference is greater than or equal to the weight difference threshold, it can be considered that the deviation between the weight of the dried nuts and the target weight is too large. If the weight difference is less than the weight difference threshold, it can be considered that the deviation between the weight of the dried nuts and the target weight is not large. The offset difference refers to the difference between the weight difference and the weight difference threshold.

[0159] Specifically, when the weight difference is greater than or equal to the preset weight difference threshold, it can be considered that the deviation between the weight of the dried nuts and the target weight is too large, and the predicted duration needs to be adjusted. At this time, the difference between the weight difference and the weight difference threshold can be obtained, that is, the offset difference. Subsequently, the predicted duration can be offset accordingly according to the offset difference. The larger the offset difference, the greater the degree of offset of the predicted duration.

[0160] S345, obtaining an offset coefficient according to the ratio of the offset difference to the reference offset difference, obtaining a delayed duration based on the product of the offset coefficient and the predicted duration, and obtaining a changed duration based on the sum of the delayed duration and the current drying duration.

[0161] Specifically, the offset coefficient can be obtained by calculating the ratio of the offset difference to a preset benchmark offset difference. The predicted duration can be adjusted by multiplying the offset coefficient by the predicted duration to obtain the corresponding delayed duration. The corresponding drying operation can be continued according to the delayed duration. The corresponding changed duration can be obtained by adding the delayed duration to the current drying time.

[0162] The offset coefficient refers to a coefficient that can be used to adjust the predicted duration, and the delayed duration refers to the drying time that is increased after the current drying time is adjusted.

[0163] Through the above implementation, the accuracy of obtaining the drying time can be improved, and it can be ensured that the nuts can be dried to the target weight within a suitable time.

[0164] S4, updating the drying parameters according to the feedback data of the drying parameters from the user end to obtain adjustment parameters, and controlling the drying device to complete the drying operation based on the adjustment parameters.

[0165] In actual applications, during the drying process, the user may adjust the drying parameters of the drying process according to actual needs. For example, the temperature during drying can be increased or decreased, and the corresponding drying time will also increase or decrease accordingly. Combined with the user's feedback data on the drying parameters, that is, the data for adjusting the temperature, the drying time is updated accordingly to obtain the updated adjustment parameters. The drying time may be the initial predicted time, or it may be the changed time after the predicted time is adjusted. The drying equipment is controlled to complete the drying operation according to the adjustment parameters, thereby ensuring that the drying process is both efficient and meets the needs of users.

[0166] The feedback data refers to the data of the temperature adjustment by the user, and the adjustment parameter refers to the parameter after the prediction duration or the change duration is adjusted.

[0167] In some embodiments, the step S4 of "updating the drying parameter to obtain the adjustment parameter according to the feedback data of the drying parameter from the user terminal" includes the following steps:

[0168] S41, obtaining a feedback temperature input by the user end, wherein the feedback data includes the feedback temperature.

[0169] Specifically, the user can adjust the temperature of the drying equipment accordingly according to his / her needs, obtain the feedback temperature input by the user at the user end, and adjust the drying parameters of the drying equipment accordingly according to the feedback temperature.

[0170] Among them, the feedback temperature refers to the temperature input by the user based on his or her own needs.

[0171] S42: if the feedback temperature is greater than the set temperature of the drying device, then shortening adjustment information is generated; if the feedback temperature is less than the set temperature, then lengthening adjustment information is generated.

[0172] Specifically, if the feedback temperature input by the user is greater than the set temperature of the drying equipment, since a higher temperature usually means a faster drying speed, it can be considered that the user wants to speed up the drying progress, and thus shortening adjustment information can be generated; if the feedback temperature is lower than the set temperature, it can be considered that the user wants to slow down the drying progress, and thus extending adjustment information can be generated.

[0173] The set temperature refers to the preset temperature of the drying device for the drying operation, the shortening adjustment information refers to the information for shortening the duration of the drying operation, and the extending adjustment information refers to the information for extending the duration of the drying operation.

[0174] S43, in response to the shortening adjustment information, adjusting the predicted duration or the changed duration corresponding to the drying parameter according to the temperature difference between the feedback temperature and the set temperature to obtain an adjustment parameter.

[0175] Specifically, when the feedback temperature is greater than the set temperature of the drying device, the shortening adjustment information can be responded to, and the predicted duration or change duration corresponding to the drying parameter can be adjusted according to the temperature difference between the feedback temperature and the set temperature, so as to obtain the corresponding adjustment parameter. The temperature difference refers to the difference between the feedback temperature and the set temperature.

[0176] Based on the above embodiment, the specific implementation of step S43 may be:

[0177] S431, in response to the shortening adjustment information, determining a shortening duration corresponding to the temperature difference between the feedback temperature and the set temperature, and obtaining an adjustment parameter according to the difference between the predicted duration or the changed duration and the shortening duration.

[0178] According to the temperature difference between the feedback temperature and the set temperature, an appropriate shortening time can be determined. In practical applications, in order to achieve precise adjustment, a list containing multiple temperature difference intervals can be pre-configured, each temperature difference interval contains a series of temperature difference value ranges, and each interval corresponds to a specific adjustment time. The calculated temperature difference is compared with each temperature difference interval in this list to determine the interval to which it belongs. After determining the interval in which the temperature difference is located, the adjustment time corresponding to the interval can be directly read, and the corresponding adjustment time can be determined as the shortening time. For example, the larger the temperature difference, the longer the shortening time may be, and the smaller the temperature difference, the shorter the shortening time may be.

[0179] After obtaining the shortened time, the predicted time or the changed time can be subtracted from the determined shortened time to obtain a new adjustment parameter, which can be used as a new drying time to guide the subsequent drying process, thereby achieving precise adjustment of temperature control during the drying process.

[0180] S44, or, in response to the extension adjustment information, adjusting the predicted duration or the changed duration corresponding to the drying parameter according to the temperature difference between the set temperature and the feedback temperature to obtain an adjustment parameter.

[0181] Specifically, when the feedback temperature is lower than the set temperature of the drying equipment, the extended adjustment information can be responded to, and the predicted duration or change duration corresponding to the drying parameter can be adjusted according to the temperature difference between the feedback temperature and the set temperature to obtain the corresponding adjustment parameter.

[0182] Based on the above embodiment, the specific implementation of step S44 may be:

[0183] S441, in response to the extended adjustment information, determining an extended time corresponding to the temperature difference between the set temperature and the feedback temperature, and obtaining an adjustment parameter according to the extended time or the sum of the changed time and the extended time.

[0184] According to the temperature difference between the set temperature and the feedback temperature, an appropriate extension time can be determined. Specifically, a list containing multiple temperature difference intervals can also be pre-configured. The calculated temperature difference is compared with each temperature difference interval in the list to determine the interval to which it belongs. After determining the interval in which the temperature difference is located, the adjustment time corresponding to the interval can be directly read, and the corresponding adjustment time can be determined as the extension time. For example, the larger the temperature difference, the longer the extension time may be, and the smaller the temperature difference, the shorter the extension time may be.

[0185] After obtaining the extended time, the predicted time or the changed time plus the determined extended time can be used to obtain a new adjustment parameter, which can be used as a new drying time to guide the subsequent drying process.

[0186] Through the above implementation, the drying time can be dynamically adjusted according to the actual temperature feedback of the user, thereby ensuring that the drying process can be carried out efficiently and in accordance with user needs, and the drying efficiency can be improved by precise control of the temperature.
