Description

Technical Field

[0001] The present invention relates to the technical field of data processing, and particularly to a traceability management system for the whole-process production and processing information of Chinese medicinal materials. Background Art

[0002] Under the background of the modernization and globalization development of traditional Chinese medicine, the production and processing of Chinese medicinal materials are becoming more refined, standardized and commercialized. With the development of intelligent technology, quality control in the production and processing process of Chinese medicinal materials has become increasingly important. Therefore, it is necessary to accurately trace the information of the production and processing of Chinese medicinal materials, record and trace the key information of each link in the production and processing process of Chinese medicinal materials to ensure the quality and safety of Chinese medicinal materials. Thus, effective supervision of the whole production and processing of Chinese medicinal materials can be realized, the quality and safety of Chinese medicinal materials can be improved, and the healthy development of the Chinese medicinal materials industry can be promoted.

[0003] Nowadays, the production and processing of traditional Chinese medicine tend to be more refined and deep-processed, with more complex processes and more rigorous processing (a unique process for the processing of Chinese medicinal materials). Due to the particularity of traditional Chinese medicine processing, the processing of traditional Chinese medicine is mainly to obtain more pure living organic components or make the medicinal properties of the medicinal materials milder. Therefore, temperature control in the processing process becomes particularly important. The processing process of Chinese medicinal materials usually includes multiple processing procedures arranged in sequence. In the processing process of Chinese medicinal materials, the relatively abnormal processing procedures will affect the medicinal quality of Chinese medicinal materials. Therefore, it is crucial to obtain the relatively abnormal processing procedures. However, the existing abnormal processing procedures are only judged by the comparison results of the temperatures of each processing procedure with the preset temperature, and the accuracy is relatively low. Summary of the Invention

[0050] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[0051] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0052] The present embodiment provides a traceability management system for information on the entire production and processing of Chinese medicinal materials. The system is used for information traceability management of the entire production and processing of Chinese medicinal materials, from which abnormal processing procedures in the production and processing of Chinese medicinal materials are obtained, making the processing links of Chinese medicinal materials more controllable and easier to grasp their quality, ensuring that the quality is traceable and reducing the re-inspection rate of Chinese medicinal materials.

[0053] The specific Chinese herbal medicines applicable to the traceability management system for the whole-process production and processing information of Chinese herbal medicines provided in this embodiment are set according to actual needs. In an exemplary embodiment, the Chinese herbal medicine is Polygonatum sibiricum as an example. During the processing and preparation of Polygonatum sibiricum, that is, during the processing process, it needs to be steamed multiple times. In the modern steaming process, in order to make Polygonatum sibiricum evenly heated during steaming, steam is transported through pipelines to conduct heat treatment on the medicine. In order to enhance the medicinal effect of Polygonatum sibiricum, yellow rice wine is added during the steaming process. However, because there is alcohol in yellow rice wine and alcohol is volatile when heated, it will cause the steam temperature to drop, thus affecting the heating process of Polygonatum sibiricum and making the processing process of Polygonatum sibiricum unable to reach the ideal state. Therefore, by collecting data such as the processing temperature and processing duration of Polygonatum sibiricum in the same batch during processing, a traceability process for the processing of Polygonatum sibiricum is constructed.

[0054] In an exemplary embodiment, temperature sensors are set in the medicine containers required for each processing step to detect the temperature time-series data of the Chinese herbal medicine during the processing corresponding to each processing step. It should be understood that the temperature acquisition frequency is set according to actual needs. The number of processing steps, the sequence of each processing step, and the processing time of each processing step are determined by the specific Chinese herbal medicine. At the same time, record the start time, end time of each processing step, and the time interval between two adjacent processing steps, etc.

[0055] For the convenience of processing Chinese herbal medicines, in this embodiment, the Chinese herbal medicines processed in the same batch are divided into multiple groups. The number of groups into which the Chinese herbal medicines processed in the same batch are divided is set according to the actual situation, and this embodiment does not make any limitations. During processing, each group of Chinese herbal medicines in the same batch is processed in sequence, that is, the first group of Chinese herbal medicines is processed first, and after going through all the processing steps, the processing is completed. Then the second group of Chinese herbal medicines is processed, and after going through the same all the processing steps, the processing is completed. Then the third group of Chinese herbal medicines is processed, and after going through the same all the processing steps, the processing is completed, and so on, until the processing of the last group of Chinese herbal medicines in the same batch is completed. Then, the number of processing steps, the sequence of each processing step, and the processing time of each processing step experienced by multiple groups of Chinese herbal medicines in the same batch are the same.

[0056] Normally, when multiple groups of Chinese herbal medicines in the same batch are processed, the temperature control in each processing step should be similar. Then, when multiple groups of Chinese herbal medicines in the same batch are processed and the temperature of a certain group of Chinese herbal medicines is different from that of the other groups in the same batch, and the greater the difference, the greater the possibility that there is an abnormality in this group of Chinese herbal medicines. Further, according to the degree of temperature difference between each processing step during processing, the abnormal processing step is located, so as to complete the traceability detection of abnormal information during the processing of Chinese herbal medicines.

[0057] Such as Figure 1As shown, the present embodiment provides a traceability management system for the whole process production and processing information of Chinese medicinal materials, including a temperature overall cumulative error acquisition module, a temperature overall change difference acquisition module, an abnormal degree acquisition module and a screening module. Among them, the temperature overall cumulative error acquisition module is used to obtain the temperature overall cumulative error of each group of Chinese medicinal materials for all processing processes according to the temperature difference and temperature change of multiple groups of Chinese medicinal materials in the same batch in the same processing process; the temperature overall change difference acquisition module is used to obtain the temperature overall change difference of each group of Chinese medicinal materials for all processing processes according to the temperature overall cumulative error of each group of Chinese medicinal materials for all processing processes, the temperature attenuation of each group of Chinese medicinal materials for each processing process, and the temperature difference of each group of Chinese medicinal materials in the same processing process; the abnormal degree acquisition module is used to obtain the abnormal degree of each processing process according to the temperature target error accumulated by each group of Chinese medicinal materials to the corresponding processing process, the temperature overall change difference and the temperature attenuation of each group of Chinese medicinal materials for each processing process; the screening module is used to screen out abnormal processing processes according to the abnormal degree of each processing process.

[0058] like Figure 2 As shown, it is a method flow chart corresponding to a traceability management system for the entire production and processing information of traditional Chinese medicine provided in this embodiment.

[0059] The following is a detailed description of each module of the traceability management system for the entire production and processing information of traditional Chinese medicine provided in this embodiment.

[0060] The temperature overall cumulative error acquisition module is used to obtain the overall cumulative temperature error of each group of Chinese medicinal materials for all processing processes based on the temperature differences and temperature changes of multiple groups of Chinese medicinal materials in the same batch in the same processing process.

[0061] The temperature data of each group of Chinese medicinal materials in the same batch in each processing step can be obtained according to the temperature sensor, so that the temperature data change curve of each group of Chinese medicinal materials in the same batch in each processing step can be obtained.

[0062] Taking Polygonatum sibiricum as an example, rice wine is added to the processing of Polygonatum sibiricum to enhance its efficacy and improve its taste. The alcohol contained in rice wine evaporates when it encounters heat during processing, which will cause the steam temperature during processing to drop, thereby affecting the heating process of Polygonatum sibiricum. This makes it impossible for Polygonatum sibiricum to reach the ideal state that the Polygonatum sibiricum product should reach under the corresponding processing process within the time of the processing process. Therefore, in order to ensure that the processing effect of the processing process is achieved within the predetermined time of the processing process, the processing temperature of the processing process will be increased, that is, the processing temperature of the current processing process will deviate from the temperature of the remaining groups of Polygonatum sibiricum in the same batch.

[0063] In an exemplary embodiment, the overall temperature cumulative error acquisition module includes a temperature error acquisition unit and an overall temperature cumulative error acquisition unit. Among them, the temperature error acquisition unit is used to obtain the temperature error of each group of Chinese herbal medicines in each processing step according to the temperature difference and temperature change of each group of Chinese herbal medicines in the same batch during the same processing step. The overall temperature cumulative error acquisition unit is used to obtain the overall temperature cumulative error of each group of Chinese herbal medicines for all processing steps according to the temperature error of each group of Chinese herbal medicines in each processing step.

[0064] In an exemplary embodiment, as Figure 3 shown, the specific implementation process of the temperature error acquisition unit includes:

[0065] Step 1-1: For any processing step, obtain the target temperature fluctuation degree according to the target temperature of each group of Chinese herbal medicines in the same batch during this processing step, and obtain the temperature change rate of each group of Chinese herbal medicines in the same batch during this processing step.

[0066] For ease of explanation, any processing step is set as the candidate processing step.

[0067] Obtain the target temperature of each group of Chinese herbal medicines in the same batch during the candidate processing step. Since each processing step takes a certain amount of time, then, each group of Chinese herbal medicines in the same batch will obtain a temperature curve during the candidate processing step, and the temperature curve involves multiple temperature values arranged in time sequence. Moreover, the temperature change of Chinese herbal medicines during the candidate processing step is usually: in the early stage of the candidate processing step, the temperature of Chinese herbal medicines is in a continuously increasing state, and after the temperature reaches a certain level, it remains stable until the candidate processing step ends. Therefore, the temperature after stabilization of each group of Chinese herbal medicines during the candidate processing step is used as the target temperature. In an exemplary embodiment, obtain the temperature change slope of each data point in the temperature curve, compare the size of the temperature change slope with a preset threshold, and the preset threshold is set according to actual needs. If the temperature change slope is less than the preset threshold, it means that the temperature change slope is small and the temperature change is relatively stable. Therefore, when there are consecutive preset numbers of temperature change slopes that are all less than the preset threshold, obtain the first data point where the temperature change slope is less than the preset threshold among the multiple data points corresponding to the consecutive preset numbers of temperature change slopes that are all less than the preset threshold, set this data point as the target inflection point, and obtain the average value of the temperature during the period from this target inflection point to the end of the candidate processing step as the target temperature. In this way, obtain the target temperature of each group of Chinese herbal medicines in each processing step.

[0068] The target temperature of each group of Chinese medicinal materials in the same batch during the candidate processing steps also serves as the candidate processing temperature of each group of Chinese medicinal materials in the same batch, that is, the processing temperature corresponding to the candidate processing step, so as to obtain the processing temperature of each group of Chinese medicinal materials in the same batch during each processing step.

[0069] Moreover, the temperature change rate of each group of Chinese medicinal materials in the same batch during the candidate processing step is also obtained. The temperature change rate reflects the speed of temperature change of Chinese medicinal materials during the candidate processing step. In an exemplary embodiment, for any group of Chinese medicinal materials, the time interval between the target inflection point of this group of Chinese medicinal materials during the candidate processing step and the start time of the candidate processing step corresponding to this group of Chinese medicinal materials is obtained, and this time interval is defined as the temperature change duration. Calculate the difference between the temperature value at the target inflection point of this group of Chinese medicinal materials during the candidate processing step and the temperature value at the start time of the candidate processing step corresponding to this group of Chinese medicinal materials, and this difference is used as the temperature change range of this group of Chinese medicinal materials during the candidate processing step. Then calculate the ratio of the temperature change range to the temperature change duration as the temperature change rate of this group of Chinese medicinal materials during the candidate processing step. By using the above method, the temperature change rate of each group of Chinese medicinal materials in the same batch during each processing step is obtained.

[0070] According to the target temperature of each group of Chinese medicinal materials during the candidate processing step, the target temperature fluctuation degree corresponding to the candidate processing step is obtained. In an exemplary embodiment, the standard deviation of the target temperature of each group of Chinese medicinal materials during the candidate processing step is calculated, and this standard deviation is used as the target temperature fluctuation degree.

[0071] Step 1-2: According to the target temperature of each group of Chinese medicinal materials in the same batch during this processing step and the differences from the target temperatures of other groups of Chinese medicinal materials in the same batch during this processing step, the comprehensive temperature difference of each group of Chinese medicinal materials relative to other groups of Chinese medicinal materials is obtained.

[0072] For any group of Chinese medicinal materials in the same batch, obtain the difference between the target temperature of this group of Chinese medicinal materials during the candidate processing step and the target temperatures of other groups of Chinese medicinal materials in the same batch during the candidate processing step, and this difference is specifically the absolute value of the difference.

[0073] Then, according to the difference between the target temperature of this group of Chinese medicinal materials during the candidate processing step and the target temperatures of other groups of Chinese medicinal materials in the same batch during the candidate processing step, the comprehensive temperature difference of this group of Chinese medicinal materials relative to other groups of Chinese medicinal materials is obtained. In an exemplary embodiment, the sum of the differences between the target temperature of this group of Chinese medicinal materials during the candidate processing step and the target temperatures of other groups of Chinese medicinal materials in the same batch during the candidate processing step is used as the comprehensive temperature difference of this group of Chinese medicinal materials relative to other groups of Chinese medicinal materials.

[0074] Step 1-3: Obtain the temperature difference of each group of traditional Chinese medicinal materials in the same batch during this processing step according to the target temperature fluctuation degree and the comprehensive temperature difference.

[0075] For any group of traditional Chinese medicinal materials in the same batch, if the target temperature fluctuation degree is smaller, it indicates that the stability of the processing temperature under the candidate processing step is better. Then, when the processing temperature difference between this group of traditional Chinese medicinal materials and other groups of traditional Chinese medicinal materials in the same batch is larger, it indicates that the temperature difference of this group of traditional Chinese medicinal materials during processing in the candidate processing step is larger, that is, the possibility of abnormalities in the candidate processing step is greater. Therefore, the temperature difference is inversely proportional to the target temperature fluctuation degree and directly proportional to the comprehensive temperature difference.

[0076] In an exemplary embodiment, the calculation formula for the temperature difference is given as follows:

[0077] ;

[0078] where x represents the x-th group of traditional Chinese medicinal materials in the same batch except the z-th group, X represents the number of groups of traditional Chinese medicinal materials in the same batch except the z-th group; a represents the a-th processing step; represents the temperature difference of the z-th group of traditional Chinese medicinal materials in the same batch during the a-th processing step, represents the target temperature of the z-th group of traditional Chinese medicinal materials in the same batch during the a-th processing step, that is, the processing temperature, represents the target temperature of the x-th group of traditional Chinese medicinal materials in the same batch during the a-th processing step, that is, the processing temperature.

[0079] represents the normalization function. The normalization method in this embodiment can adopt the linear normalization method, or it can be the function, or the following normalization method can also be adopted: , where n is the input data, is the exponential function with the natural constant e as the base.

[0080] represents the target temperature fluctuation degree, represents the negative correlation normalization of the target temperature fluctuation degree . The method of negative correlation normalization in this embodiment can be: .

[0081] represents the comprehensive temperature difference of the z-th group of traditional Chinese medicinal materials in the same batch with respect to other groups of traditional Chinese medicinal materials.

[0082] Steps 1-4: Obtain the temperature change rate of each group of Chinese medicinal materials in the same batch during this processing step, and the temperature change rate difference from the temperature change rates of other groups of Chinese medicinal materials in the same batch during this processing step.

[0083] During the processing and preparation of Chinese medicinal materials, different processing steps have a certain degree of continuity and stability. An abnormal increase in the processing temperature of a certain processing step will cause abnormal temperature changes in the Chinese medicinal materials under this processing step. Then, when the Chinese medicinal materials enter the next processing step and the next processing step processes the Chinese medicinal materials according to the original processing step, due to the abnormal increase in temperature in the previous processing step, it will lead to abnormal accumulation of temperature changes during its processing. The accumulation of multiple processing steps will form an abnormal accumulation and superposition of temperature changes. For example, during the processing (steaming) of Polygonatum sibiricum, due to the heat absorption of alcohol, at the beginning of processing, there is a relatively large amount of alcohol in the Polygonatum sibiricum. The alcohol volatilizes and absorbs heat when heated, which has a greater impact on the processing of Polygonatum sibiricum, resulting in a slower temperature change rate of Polygonatum sibiricum. As the processing step progresses, the residual alcohol content in the Polygonatum sibiricum decreases, and its impact on the processing of Polygonatum sibiricum gradually decreases, which will cause the temperature change rate of Polygonatum sibiricum to gradually increase, resulting in the accumulation of temperature change errors.

[0084] Then, for any group of Chinese medicinal materials in the same batch, first obtain the temperature change rate of this group of Chinese medicinal materials in the candidate processing step, and the temperature change rate difference from the temperature change rates of other groups of Chinese medicinal materials in the same batch in the candidate processing step. The temperature change rate difference is specifically the absolute value of the difference in temperature change rates.

[0085] Steps 1-5: Obtain the temperature error of each group of Chinese medicinal materials in the same batch during this processing step based on the temperature difference and the temperature change rate difference of each group of Chinese medicinal materials in the same batch during this processing step.

[0086] For any group of Chinese medicinal materials in the same batch, obtain the temperature error of this group of Chinese medicinal materials in the candidate processing step based on the temperature difference and the temperature change rate difference of this group of Chinese medicinal materials in the candidate processing step. The greater the temperature difference, the greater the temperature error; the greater the temperature change rate difference, the greater the temperature error. Therefore, the temperature error is proportional to the temperature difference and the temperature change rate difference.

[0087] In an exemplary embodiment, the calculation formula for the temperature error is as follows:

[0088] ;

[0089] Wherein, represents the temperature error of the z-th group of Chinese medicinal materials in the same batch for the a-th processing step; represents the temperature change rate of the z-th group of Chinese herbal medicines in the a-th processing step of the same batch, represents the temperature change rate of the x-th group of Chinese herbal medicines in the a-th processing step of the same batch.

[0090] As the confidence coefficient of the temperature error of the z-th group of Chinese herbal medicines for the a-th processing step, the larger it is, the higher the credibility of the temperature error.

[0091] By adopting the above process, the temperature errors of each group of Chinese herbal medicines in the same batch in each processing step are obtained.

[0092] The specific implementation process of the temperature overall cumulative error acquisition unit is as follows: for any group of Chinese herbal medicines, obtain the difference in temperature errors between two adjacent processing steps of this group of Chinese herbal medicines; fuse the differences in temperature errors between all adjacent two processing steps of this group of Chinese herbal medicines to obtain the temperature overall cumulative error of this group of Chinese herbal medicines for all processing steps.

[0093] In an exemplary embodiment, the calculation formula for the temperature overall cumulative error of this group of Chinese herbal medicines for all processing steps is as follows:

[0094] ;

[0095] where, represents the temperature overall cumulative error of the z-th group of Chinese herbal medicines in the same batch for all processing steps, and A represents the total number of processing steps; represents the temperature error of the z-th group of Chinese herbal medicines in the same batch for the (a + 1)-th processing step. Among them, the (a + 1)-th processing step is the next adjacent processing step to the a-th processing step.

[0096] Since and the magnitude relationship between them is uncertain. Therefore, is not necessarily a positive value, and it may also be 0 or a negative value. Then, is not necessarily a positive value, and it may also be 0 or a negative value. To normalize , the following method can be adopted here: obtain the corresponding to each group of Chinese herbal medicines in the same batch, then obtain the maximum value and the minimum value from them, and adopt the maximum-minimum normalization method for normalization to ensure that even if there are negative values, they can be included in the numerical range of 0 - 1.

[0097] When When it indicates that the temperature error of the z-th group of Chinese medicinal materials for the (a + 1)-th processing step is greater than the temperature error of the z-th group of Chinese medicinal materials for the a-th processing step, the cumulative error of the temperature change shows an accumulation during the processing steps. When the difference in temperature change between all processing steps is greater, that is the greater it is, the greater the cumulative error rate of the temperature change during the processing of the z-th group of Chinese medicinal materials, that is, the greater the possibility of abnormality of the z-th group of Chinese medicinal materials.

[0098] Because when performing the processing steps of Chinese medicinal materials, the time intervals between adjacent two processing steps are different, that is, the time lengths of the time intervals between the end moment of the previous processing step and the start moment of the adjacent next processing step are different. Under different time intervals, the degrees of temperature change are also different. That is, the degrees of temperature attenuation (the degrees of temperature drop) are different. Under the condition of the same temperature difference, the longer the time interval between adjacent two processing steps, the greater the temperature attenuation. Because there are time intervals between adjacent processing steps, different time intervals and different processing temperatures will affect the temperature attenuation of Chinese medicinal materials for each processing step. Therefore, it is necessary to obtain the temperature attenuation of each group of Chinese medicinal materials for each processing step. In an exemplary embodiment, as Figure 4 shown, the process of obtaining the temperature attenuation of each group of Chinese medicinal materials for each processing step includes:

[0099] Step 2-1: For any group of Chinese medicinal materials, obtain the temperature difference between each processing step of this group of Chinese medicinal materials and the adjacent next processing step, and obtain the time interval between the end moment of each processing step of this group of Chinese medicinal materials and the start moment of the adjacent next processing step.

[0100] Step 2-2: According to the temperature difference and the time interval, obtain the temperature attenuation coefficient of each group of Chinese medicinal materials for each processing step.

[0101] Among them, the greater the temperature difference between the processing steps and the longer the time interval, the greater the temperature attenuation coefficient, that is, the temperature attenuation coefficient is proportional to the temperature difference between the processing steps and the time interval.

[0102] In an exemplary embodiment, the following gives the calculation formula of the temperature attenuation coefficient:

[0103] ;

[0104] Among them, represents the temperature attenuation coefficient of the z-th group of Chinese medicinal materials for the a-th processing step in the same batch; represents the target temperature, that is, the processing temperature, of the z-th group of Chinese medicinal materials in the (a + 1)-th processing step in the same batch; It represents the time interval between the end time of the a-th processing step of the z-th group of Chinese herbal medicines in the same batch and the start time of the (a + 1)-th processing step.

[0105] It represents the difference in processing temperature between the a-th processing step and the (a + 1)-th processing step of the z-th group of Chinese herbal medicines in the same batch. The greater the difference in processing temperature, and the greater the time interval between two adjacent processing steps, the greater the temperature attenuation coefficient, that is the greater it is. Then, when the temperature attenuation coefficient is greater, it indicates a greater possibility of abnormality, and the abnormality may exist in this processing step.

[0106] It should be understood that by using the above process, the temperature attenuation coefficient corresponding to the last processing step cannot be obtained. Therefore, in this embodiment, the average value of the temperature attenuation coefficients of each group of Chinese herbal medicines from the first processing step to the penultimate processing step is used as the temperature attenuation coefficient of each group of Chinese herbal medicines in the last processing step, that is: , It represents the temperature attenuation coefficient of the z-th group of Chinese herbal medicines in the same batch for the A-th processing step (i.e., the last processing step).

[0107] The temperature overall change difference acquisition module is used to obtain the temperature overall change difference of each group of Chinese herbal medicines for all processing steps according to the temperature overall cumulative error of each group of Chinese herbal medicines for all processing steps, the temperature attenuation situation of each group of Chinese herbal medicines for each processing step, and the temperature difference situation of each group of Chinese herbal medicines in the same processing step.

[0108] In an exemplary embodiment, the calculation formula for the temperature overall change difference is as follows:

[0109] ;

[0110] Wherein, It represents the temperature overall change difference of the z-th group of Chinese herbal medicines for all processing steps.

[0111] The greater the temperature overall cumulative error, that is, the temperature curves of Chinese herbal medicines under all processing steps will have an increasing difference as the temperature overall cumulative error increases, and ultimately the abnormality significance of the temperature will be higher, that is, the greater the temperature overall change difference.

[0112] For the processing of traditional Chinese medicinal materials in each group of the same batch, the greater the difference in the processing temperature between the z-th group of traditional Chinese medicinal materials and other groups of traditional Chinese medicinal materials in the same batch, the greater the possibility of abnormality in the z-th group of traditional Chinese medicinal materials. And the temperature attenuation coefficient is used as a correction coefficient to obtain the overall temperature change difference of the z-th group of traditional Chinese medicinal materials for all processing procedures. The greater the overall temperature change difference, the greater the possibility of abnormality.

[0113] The abnormality degree acquisition module is used to obtain the abnormality degree of each processing procedure according to the temperature target error, the overall temperature change difference, and the temperature attenuation situation of each group of traditional Chinese medicinal materials for each processing procedure accumulated to the corresponding processing procedure. As Figure 5 shown, the specific implementation process of the abnormality degree acquisition module includes:

[0114] Step 3-1: Obtain the comprehensive temperature attenuation difference corresponding to each processing procedure of each group of traditional Chinese medicinal materials according to the difference in the temperature attenuation situation of each group of traditional Chinese medicinal materials for each processing procedure and other processing procedures.

[0115] Step 3-2: Obtain the abnormality degree of each processing procedure according to the temperature target error, the overall temperature change difference, and the comprehensive temperature attenuation difference corresponding to each processing procedure of each group of traditional Chinese medicinal materials accumulated to the corresponding processing procedure.

[0116] In an exemplary embodiment, the calculation formula of the abnormality degree is as follows:

[0117] ;

[0118] ;

[0119] ;

[0120] Wherein, represents the abnormal sub-degree of the z-th group of traditional Chinese medicinal materials in the same batch for the a-th processing procedure, represents the abnormal degree of the a-th processing procedure, represents the temperature attenuation coefficient of the z-th group of traditional Chinese medicinal materials in the same batch for the b-th processing procedure, and the b-th processing procedure and the a-th processing procedure are different processing procedures; A-1 represents the number of the remaining processing procedures except the a-th processing procedure; Z represents the total number of groups of traditional Chinese medicinal materials in the same batch.

[0121] represents the temperature target error of the z-th group of traditional Chinese medicinal materials in the same batch accumulated to the a-th processing procedure, represents the temperature error of the z-th group of traditional Chinese medicinal materials in the same batch for the c-th processing procedure, Denote the temperature error of the z-th group of Chinese herbal medicines in the same batch for the (c + 1)-th processing step. For example, assume that the a-th processing step is the 3rd processing step. Then, the cumulative temperature target error of the z-th group of Chinese herbal medicines in the same batch up to the a-th processing step is equal to: the temperature error of the z-th group of Chinese herbal medicines for the 1st processing step plus the temperature error of the z-th group of Chinese herbal medicines for the 2nd processing step plus the temperature error of the z-th group of Chinese herbal medicines for the 3rd processing step. It should be understood that since there is no processing step after the last processing step, that is, since the A-th processing step is the last processing step, there is no (A + 1)-th processing step after the A-th processing step, and thus there is no temperature error of the z-th group of Chinese herbal medicines in the same batch for the (A + 1)-th processing step , therefore, set: , Denote the cumulative temperature target error of the z-th group of Chinese herbal medicines in the same batch up to the A-th processing step (i.e., the last processing step), Denote the cumulative temperature target error of the z-th group of Chinese herbal medicines in the same batch up to the (A - 1)-th processing step (i.e., the penultimate processing step).

[0122] Taking and as weights, when and are larger, it indicates that the possibility of an abnormal processing step existing in the entire processing flow is greater. Moreover, if an abnormal situation occurs in a certain processing step, that is, the temperature is abnormal, then it will inevitably increase the comprehensive difference in temperature attenuation under this processing step. Therefore, the larger the temperature target error, the overall temperature change difference, and the comprehensive temperature attenuation difference, the higher the degree of abnormality of each group of Chinese herbal medicines in the same batch for the corresponding processing step, that is, the higher the degree of abnormal sub-level of each group of Chinese herbal medicines in the same batch for each processing step. Then, comprehensively consider the degree of abnormal sub-level of each group of Chinese herbal medicines in the same batch for each processing step to obtain the degree of abnormality of each processing step

[0123] Adopt the above process to obtain the degree of abnormality of each processing step

[0124] The screening module is used to screen out the abnormal processing steps according to the degree of abnormality of each processing step

[0125] In an exemplary embodiment, as Figure 6 shown, the specific implementation process of the screening module includes:

[0126] Step 4-1: Compare the degree of abnormality of each processing step with the preset abnormality degree threshold

[0127] Step 4-2: Determine the processing steps corresponding to the degree of abnormality greater than or equal to the preset abnormality degree threshold as the abnormal processing steps

[0128] The higher the degree of abnormality, the more abnormal the corresponding processing step is. Therefore, a threshold value of the degree of abnormality is preset, and the numerical range of the preset threshold value of the degree of abnormality is 0-1, and the specific value of the preset threshold value of the degree of abnormality is set according to actual judgment needs.

[0129] Compare the degree of abnormality of each processing step with the preset threshold value of the degree of abnormality, obtain the degree of abnormality greater than or equal to the preset threshold value of the degree of abnormality, and determine the processing step corresponding to the degree of abnormality greater than or equal to the preset threshold value of the degree of abnormality as an abnormal processing step. Thus, the processing steps with abnormalities are obtained. Subsequently, the abnormal processing steps can be visualized to facilitate the staff to obtain them intuitively, so as to take relevant solutions.
