Description

Technical Field

[0001] The present invention relates to the technical field of storage monitoring, and in particular to a Chinese medicinal material storage monitoring system and method based on scene analysis. Background Art

[0002] As an important part of traditional medicine, the quality of Chinese medicinal materials directly affects the efficacy of the medicine, so the storage and management of Chinese medicinal materials are widely valued. The nature and quality of Chinese medicinal materials are often affected by storage conditions, especially environmental factors such as temperature and humidity, light, and air quality. These factors will have a significant impact on the effective ingredients, efficacy, and appearance of the medicinal materials. For example, excessive temperature and humidity can easily cause Chinese medicinal materials to absorb moisture, volatilize, and mildew, reducing their medicinal value. Therefore, ensuring that Chinese medicinal materials are stored in a reasonable environment is the key to maintaining their efficacy and extending their shelf life.

[0003] Traditional storage management methods for Chinese herbal medicines are usually manual inspection and empirical judgment, which evaluates the preservation of Chinese herbal medicines through visual inspection, olfactory perception, weighing, etc. This method relies more on the work experience and professional skills of managers. Manual inspection may not fully cover the storage environment of all herbal medicines, making it difficult to monitor herbal medicines in a timely manner, resulting in certain losses of herbal medicines.

[0004] With the development of technologies such as the Internet of Things and artificial intelligence, intelligent monitoring and management systems have gradually become the direction for improving storage management efficiency. The Internet of Things technology can realize real-time monitoring of the storage environment, automatically collect environmental data such as temperature, humidity, and light, and remotely transmit it to the cloud platform or local server, so that managers can view and analyze it at any time.

[0005] In view of the above technical solutions, the existing monitoring systems usually perform unified analysis and environmental control of environmental parameters such as temperature, humidity and light, and are unable to make precise adjustments based on the characteristics of different Chinese medicinal materials, thereby increasing the loss of Chinese medicinal materials. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a Chinese medicinal material storage monitoring system and method based on scene analysis, which can be accurately adjusted according to the characteristics of different Chinese medicinal materials, meet the efficiency and accuracy requirements of modern Chinese medicinal material storage management, and help reduce the loss of Chinese medicinal materials.

[0007] In the first aspect, the present invention provides a Chinese medicinal material storage monitoring system based on scene analysis, which adopts the following technical solutions to achieve the purpose of the invention:

[0008] The Chinese herbal medicine storage monitoring system based on scenario analysis includes the following modules:

[0009] Acquisition module I: The output end is connected to the input end of the analysis module I. The storage area is provided with N units in total, which are used to acquire the type and storage requirements of the Chinese medicinal materials entered in each unit, and set the optimal storage conditions of the corresponding unit. The optimal storage conditions include the optimal temperature and humidity, ventilation cycle, and ventilation duration;

[0010] Analysis module I: the input end is connected to the output end of acquisition module I and the output end of judgment module II respectively, and the output end is connected to the input end of judgment module I, and is used to monitor and obtain the temperature and humidity data in the storage environment of N units, and compare the temperature and humidity data of N units with the optimal temperature and humidity in turn, and analyze whether the current environment meets the storage requirements of Chinese medicinal materials;

[0011] Judgment module I: the input end is connected to the output end of the analysis module I, and the output end is connected to the input end of the adjustment module I and the input end of the judgment module II respectively, and is used to judge if the temperature and humidity data of the nth unit does not meet the optimal temperature and humidity, and execute the adjustment module I, otherwise, execute the judgment module II, wherein n=1, 2, ..., N;

[0012] Adjustment module I: the input end is connected to the output end of the judgment module I, and is used to adjust the temperature and humidity in the storage environment of the nth unit to the optimal temperature and humidity;

[0013] Judgment module II: the input end is connected to the output end of the judgment module I, and the output end is connected to the input end of the analysis module I and the input end of the analysis module II respectively, and is used to obtain the difference between the last ventilation time and the current time in the storage environment of the nth unit. If the difference of the unit is greater than or equal to one ventilation cycle, the analysis module II is executed, otherwise, the analysis module I is executed;

[0014] Analysis module II: the input end is connected to the output end of the judgment module II, and the output end is connected to the input end of the adjustment module II, and is used to obtain the temperature and humidity change curve in the outdoor environment, and adjust the current ventilation time of the nth unit according to the temperature and humidity change curve;

[0015] Adjustment module II: The input end is connected to the output end of the analysis module II, and is used to ventilate the unit according to the adjusted ventilation time. After the ventilation time is reached, the ventilation is stopped and the ventilation time is recorded.

[0016] By adopting the above technical solution, Chinese medicinal materials are classified and stored according to storage units. The acquisition module I sets the optimal storage conditions of each storage unit by acquiring the storage requirements of the Chinese medicinal materials in each storage unit. The analysis module I monitors and acquires the storage environment of each unit, and real-time grasps and records the environmental data such as temperature and humidity of each unit. The judgment module I compares the temperature and humidity data with the optimal storage conditions, and can dynamically identify which units' environments do not meet the requirements, and warn of potential environmental problems in advance; when the judgment module I monitors that the temperature and humidity data of one of the units do not meet the optimal temperature and humidity, the adjustment module I adjusts the temperature and humidity in the storage environment of the unit to the optimal temperature and humidity, and accurately adjusts according to the storage requirements of the Chinese medicinal materials in the unit, and can selectively adopt humidification, dehumidification, insulation or low-temperature drying for the unit. Dry operations, thereby effectively reducing the loss of medicinal materials and improving the efficiency and accuracy of modern Chinese medicinal materials storage management; when the judgment module II monitors that the difference between the last ventilation time and the current time of one of the units is greater than or equal to one ventilation cycle, that is, when the unit reaches this ventilation time, the temperature and humidity change curve in the outdoor environment is obtained by analyzing the module II, and the ventilation time of the nth unit is flexibly adjusted according to the temperature and humidity change curve. This method has strong dynamic adaptability, can comprehensively consider different environmental factors, and automatically adjust and optimize according to different storage conditions and medicinal materials characteristics. It can cope with changeable storage conditions, accurately control the ventilation process, and reduce unnecessary waste of resources, thereby effectively reducing the loss of medicinal materials and improving the efficiency and accuracy of modern Chinese medicinal materials storage management.

[0017] As a further limitation of the technical solution, it also includes an analysis module III, a feedback module I and a calculation module;

[0018] Analysis module III: the input end is connected to the output end of the analysis module II, and the output end is connected to the input end of the feedback module I, and is used to obtain the corresponding upper limit of the mold content according to the type of the Chinese medicinal materials entered in the nth unit, obtain the mold content in the storage environment of the nth unit, and record it as the first mold content;

[0019] Feedback module I: the input end is connected to the output end of the analysis module III, and the output end is connected to the input end of the adjustment module II, and is used to send an alarm to the management end if the first mold content of the nth unit is greater than or equal to the upper limit of the mold content;

[0020] Calculation module: The input end is connected to the output end of the regulation module II, and is used to obtain the mold content in the storage environment of the nth unit after ventilation is stopped, recorded as the second mold content, and calculate the mold loss rate = (first mold content-second mold content) / this ventilation time, and add a certain amount of mildew inhibitor to the storage environment of the nth unit according to the mold loss rate.

[0021] By adopting the above technical solution, the analysis module III obtains the first mold content of the unit. If it is higher than the upper limit of the mold content, an alarm is issued to the management end. Since special types of Chinese medicinal materials carry molds or emit spores, the upper limit of the mold content is flexibly set according to the type of Chinese medicinal materials entered. The feedback module I dynamically identifies which units have abnormal storage environments or which units of Chinese medicinal materials have deteriorated, thereby improving the efficiency and accuracy requirements of Chinese medicinal materials storage management, which is conducive to reducing the loss of Chinese medicinal materials; the calculation module obtains the second mold content in the storage environment of the unit after ventilation is stopped, and analyzes the failure of the anti-mold agent in the storage environment by calculating the mold loss rate of the unit, so as to timely remind the staff to add a certain amount of anti-mold agent to the storage environment, thereby effectively reducing the loss of medicinal materials and reducing unnecessary waste of resources; such a setting can comprehensively consider different environmental factors, automatically adjust and optimize according to different storage conditions and medicinal material characteristics, can cope with variable storage conditions, is conducive to early identification and early warning of potential environmental safety problems, reduce unnecessary waste of resources, thereby effectively reducing the loss of medicinal materials, and improving the efficiency and accuracy of modern Chinese medicinal materials storage management.

[0022] As a further limitation of the technical solution, it also includes a feedback module II;

[0023] In the analysis module III, it is also used to obtain the carbon dioxide content in the storage environment of the nth unit;

[0024] The feedback module I is updated as follows: the input end is connected to the output end of the analysis module III, and the output end is connected to the input end of the feedback module II, so as to send an alarm to the management end if the first mold content of the nth unit is greater than or equal to the upper limit of the mold content, and vice versa, execute the feedback module II;

[0025] Feedback module II: the input end is connected to the output end of the feedback module I, and the output end is connected to the input end of the adjustment module II, and is used to perform secondary adjustment on the current ventilation time of the nth unit according to the carbon dioxide content.

[0026] By adopting the above technical solution, since some Chinese medicinal materials still have biological activity during storage, they can release or absorb carbon dioxide in the storage unit, and too high or too low carbon dioxide content has different effects on the growth of different types of molds. Therefore, the carbon dioxide content is obtained through the analysis module III, and the feedback module II further adjusts the ventilation time according to the carbon dioxide content. By comprehensively monitoring the changes in environmental factors such as temperature and humidity, mold content, and carbon dioxide content, the adjustment module II flexibly adjusts the ventilation time. This method has strong dynamic adaptability, can comprehensively consider different environmental factors, and automatically adjust and optimize according to different storage conditions and medicinal material characteristics. It can cope with variable storage conditions, is conducive to early identification and early warning of potential environmental safety issues, accurately control the ventilation process, and reduce unnecessary waste of resources, thereby effectively reducing the loss of medicinal materials and improving the efficiency and accuracy of modern Chinese medicinal materials storage management.

[0027] As a further limitation of the present technical solution, the analysis module II is updated as follows: the input end is connected to the output end of the judgment module II, and the output end is connected to the input end of the adjustment module II, and is used to obtain the temperature and humidity change curve in the outdoor environment. If the ventilation time of the nth unit is not zero, the ventilation time of the nth unit is adjusted according to the temperature and humidity change curve.

[0028] By adopting the above technical solution, if the ventilation time of the unit is not zero, by obtaining the temperature and humidity change curve in the outdoor environment, the current ventilation time of the nth unit is adjusted according to the temperature and humidity change curve; if the ventilation time of the unit is zero, it means that the Chinese medicinal materials in the unit are usually sealed and packaged, so ventilation is not required. Such a setting can accurately control the ventilation process, reduce unnecessary waste of resources, improve the efficiency and accuracy of modern Chinese medicinal materials storage management, and help reduce cross contamination, thereby effectively reducing the loss of medicinal materials.

[0029] As a further limitation of the technical solution, it also includes a damage detection module;

[0030] The analysis module II is updated as follows: the input end is connected to the output end of the judgment module II, and the output end is connected to the input end of the adjustment module and the input end of the damage detection module respectively, so as to obtain the temperature and humidity change curve in the outdoor environment. If the ventilation time of the nth unit is not zero, the ventilation time of the nth unit is adjusted according to the temperature and humidity change curve. Otherwise, the damage detection module is executed.

[0031] Damage detection module: The input end is connected to the output end of the analysis module II, and the detection cycle is set to T. It is used to obtain the temperature and humidity change curve of the storage environment of the nth unit in a detection cycle, and calculate the Pearson correlation coefficient with the temperature and humidity change curve of the previous detection cycle. If the absolute value of the correlation coefficient is less than 0.5, an alarm is issued to the management end.

[0032] By adopting the above technical solution, if the ventilation time of the unit is zero, it means that the Chinese medicinal materials in the unit are usually sealed and packaged, so ventilation is not required. Only package damage detection is required. The temperature and humidity change curves of the unit in one detection cycle and the previous detection cycle are obtained through the damage detection module, and the Pearson correlation coefficient is calculated. If the absolute value of the correlation coefficient is less than 0.5, it means that the temperature and humidity changes in the unit environment are abnormal, which is usually caused by packaging failure or damage. At this time, an alarm is sent to the management end to remind the staff to check the storage situation of the Chinese medicinal materials in the unit in time and replace the packaging in time. Such a setting can accurately control the ventilation process, reduce unnecessary waste of resources, reduce cross contamination, and thus effectively reduce the loss of medicinal materials.

[0033] In a second aspect, the present invention provides a method for monitoring storage of Chinese medicinal materials based on scene analysis, which uses the following technical solutions to achieve the purpose of the invention:

[0034] The Chinese medicinal materials storage monitoring method based on scenario analysis includes the following steps:

[0035] Obtaining data I: There are N units in the storage area. Obtain the types and storage requirements of the Chinese medicinal materials entered in each unit, and set the optimal storage conditions of the corresponding unit. The optimal storage conditions include the optimal temperature and humidity, ventilation cycle, and ventilation duration;

[0036] Scenario Analysis I: Monitor and obtain the temperature and humidity data in the storage environment of N units, compare the temperature and humidity data of N units with the optimal temperature and humidity in turn, and analyze whether the current environment meets the storage requirements of Chinese medicinal materials;

[0037] Judgment I: If the temperature and humidity data of the nth unit do not meet the optimal temperature and humidity, execute the adjustment step I, otherwise, execute the judgment step II, where n = 1, 2, ..., N;

[0038] Adjustment I: Adjust the temperature and humidity in the storage environment of the nth unit to the optimal temperature and humidity;

[0039] Judgment II: Obtain the difference between the last ventilation time and the current time in the storage environment of the nth unit. If the difference of the unit is greater than or equal to one ventilation cycle, execute the scene analysis II step; otherwise, execute the scene analysis I step;

[0040] Scenario analysis II: Obtain the temperature and humidity change curve in the outdoor environment, and adjust the ventilation time of the nth unit according to the temperature and humidity change curve;

[0041] Adjustment II: Ventilate the unit according to the adjusted ventilation time. When the ventilation time is reached, stop ventilation and record the ventilation time.

[0042] By adopting the above technical solution, Chinese medicinal materials are classified and stored according to storage units. By obtaining the storage requirements of Chinese medicinal materials in each storage unit, the optimal storage conditions of the unit are set. By monitoring and obtaining the storage environment of each unit, the environmental data such as temperature and humidity of each unit can be mastered and recorded in real time. By comparing the temperature and humidity data with the optimal storage conditions, it is possible to dynamically identify which units' environments do not meet the requirements, and give early warning of potential environmental problems. When it is monitored that the temperature and humidity data of one of the units do not meet the optimal temperature and humidity, the temperature and humidity in the storage environment of the unit are adjusted to the optimal temperature and humidity, and accurately adjusted according to the storage requirements of the Chinese medicinal materials in the unit. The unit can be selectively humidified, dehumidified, kept warm or dried at low temperature, thereby effectively reducing the loss of medicinal materials and improving the efficiency and accuracy of modern Chinese medicinal materials storage management; when it is monitored that the difference between the last ventilation time and the current time of one of the units is greater than or equal to one ventilation cycle, that is, when the unit reaches the current ventilation time, the temperature and humidity change curve in the outdoor environment is obtained to flexibly adjust the ventilation time. This method has strong dynamic adaptability, can comprehensively consider different environmental factors, and automatically adjust and optimize according to different storage conditions and medicinal materials characteristics. It can cope with changing storage conditions, accurately control the ventilation process, and reduce unnecessary waste of resources, thereby effectively reducing the loss of medicinal materials and improving the efficiency and accuracy of modern Chinese medicinal materials storage management.

[0043] As a further limitation of the present technical solution, a scene analysis III step and a feedback I step are further provided between the scene analysis II step and the adjustment II step;

[0044] Scenario Analysis III: Obtain the corresponding upper limit of mold content according to the type of Chinese medicinal materials entered in the nth unit, obtain the mold content in the storage environment of the nth unit, and record it as the first mold content;

[0045] Feedback I: If the first mold content of the nth unit is greater than or equal to the upper limit of the mold content, an alarm is sent to the management end;

[0046] A calculation step is also provided after the adjustment II step;

[0047] Calculation: Obtain the mold content in the storage environment of the nth unit after ventilation is stopped, record it as the second mold content, calculate the mold loss rate = (first mold content - second mold content) / duration of this ventilation, and add a certain amount of mildew inhibitor to the storage environment of the nth unit according to the mold loss rate.

[0048] By adopting the above technical solution, the first mold content of the unit is obtained. If it is higher than the upper limit of the mold content, an alarm is issued to the management end. Since special types of Chinese medicinal materials carry molds or emit spores, the upper limit of the mold content is flexibly set according to the type of Chinese medicinal materials entered, so as to dynamically identify which units have abnormal storage environments or which units of Chinese medicinal materials have deteriorated, improve the efficiency and accuracy of Chinese medicinal materials storage management, and help reduce the loss of Chinese medicinal materials; obtain the second mold content in the storage environment of the unit after stopping ventilation, calculate the mold loss rate of the unit, analyze the failure of the anti-mold agent in the storage environment, and timely remind the staff to add a certain amount of anti-mold agent to the storage environment, thereby effectively reducing the loss of medicinal materials and reducing unnecessary waste of resources; such a setting can comprehensively consider different environmental factors, automatically adjust and optimize according to different storage conditions and medicinal material characteristics, can cope with variable storage conditions, and is conducive to early identification and early warning of potential environmental safety issues, reduce unnecessary waste of resources, thereby effectively reducing the loss of medicinal materials and improving the efficiency and accuracy of modern Chinese medicinal materials storage management.

[0049] As a further limitation of the technical solution, a feedback II step is further provided between the feedback I step and the adjustment II step;

[0050] In the scenario analysis III step, the carbon dioxide content in the storage environment of the nth unit is also obtained;

[0051] The feedback step I is updated as follows: if the first mold content of the nth unit is greater than or equal to the upper limit of the mold content, an alarm is issued to the management end; otherwise, the feedback step II is executed;

[0052] Feedback II: Secondary adjustment of the ventilation duration of the nth unit according to the carbon dioxide content.

[0053] By adopting the above technical scheme, since some Chinese medicinal materials still have biological activity during storage and can release or absorb carbon dioxide in the storage unit, and too high or too low carbon dioxide content has different effects on the growth of different types of mold, the ventilation duration is further adjusted by detecting the carbon dioxide content, and the ventilation duration is flexibly adjusted by comprehensively monitoring the changes in environmental factors such as temperature and humidity, mold content, and carbon dioxide content. This method has strong dynamic adaptability, can comprehensively consider different environmental factors, and automatically adjust and optimize according to different storage conditions and medicinal material characteristics. It can cope with changing storage conditions, is conducive to early identification and warning of potential environmental safety issues, accurately control the ventilation process, and reduce unnecessary waste of resources, thereby effectively reducing the loss of medicinal materials and improving the efficiency and accuracy of modern Chinese medicinal materials storage management.

[0054] As a further limitation of the present technical solution, the scene analysis II step is updated as follows: obtaining the temperature and humidity change curve in the outdoor environment, and if the ventilation time of the nth unit is not zero, adjusting the current ventilation time of the nth unit according to the temperature and humidity change curve.

[0055] By adopting the above technical solution, if the ventilation time of the unit is not zero, by obtaining the temperature and humidity change curve in the outdoor environment, the current ventilation time of the nth unit is adjusted according to the temperature and humidity change curve; if the ventilation time of the unit is zero, it means that the Chinese medicinal materials in the unit are usually sealed and packaged, so ventilation is not required; such a setting can accurately control the ventilation process, reduce unnecessary waste of resources, improve the efficiency and accuracy of modern Chinese medicinal materials storage management, and help reduce cross contamination, thereby effectively reducing the loss of medicinal materials.

[0056] As a further limitation of the technical solution, a damage detection step is also provided after the scene analysis II step;

[0057] The scene analysis II step is updated as follows: obtaining the temperature and humidity change curve in the outdoor environment, and if the ventilation time of the nth unit is not zero, adjusting the current ventilation time of the nth unit according to the temperature and humidity change curve, otherwise, executing the damage detection step;

[0058] Damage detection: Set the detection cycle to T, obtain the temperature and humidity change curve of the storage environment of the nth unit in a detection cycle, and calculate the Pearson correlation coefficient with the temperature and humidity change curve of the previous detection cycle. If the absolute value of the correlation coefficient is less than 0.5, an alarm is issued to the management end.

[0059] By adopting the above technical solution, if the ventilation time of the unit is zero, it means that the Chinese medicinal materials in the unit are usually sealed and packaged, so ventilation is not required. Only packaging damage detection is required. By obtaining the temperature and humidity change curves of the unit in one detection cycle and the previous detection cycle, and calculating the Pearson correlation coefficient, if the absolute value of the correlation coefficient is less than 0.5, it means that the temperature and humidity changes in the unit environment are abnormal, which is usually caused by packaging failure or damage. At this time, an alarm is sent to the management end to remind the staff to check the storage situation of the Chinese medicinal materials in the unit in time and replace the packaging in time. Such a setting can accurately control the ventilation process, reduce unnecessary waste of resources, reduce cross contamination, and thus effectively reduce the loss of medicinal materials.

[0060] Compared with the prior art, the advantages and positive effects of the present invention are:

[0061] 1. By monitoring and obtaining the storage environment of each unit, the temperature and humidity and other environmental data of each unit can be mastered and recorded in real time, and the temperature and humidity data can be compared with the optimal storage conditions to dynamically identify which units' environments do not meet the requirements, and to warn of potential environmental problems in advance. It can be precisely adjusted according to the storage requirements of the Chinese medicinal materials in the unit, and can selectively take humidification, dehumidification, insulation or low-temperature drying operations on the unit, thereby effectively reducing the loss of medicinal materials and improving the efficiency and accuracy of modern Chinese medicinal materials storage management; when the unit is monitored to reach the current ventilation time, the temperature and humidity change curve in the outdoor environment is obtained to flexibly adjust the ventilation time. This method has strong dynamic adaptability, can comprehensively consider different environmental factors, and automatically adjust and optimize according to different storage conditions and medicinal materials characteristics. It can cope with variable storage conditions, accurately control the ventilation process, and reduce unnecessary resource waste, thereby effectively reducing the loss of medicinal materials and improving the efficiency and accuracy of modern Chinese medicinal materials storage management.

[0062] 2. Since special types of Chinese medicinal materials contain mold or emit spores, the upper limit of mold content can be flexibly set according to the type of Chinese medicinal materials entered, so as to dynamically identify which units have abnormal storage environments or which units of Chinese medicinal materials have deteriorated, thereby improving the efficiency and accuracy of Chinese medicinal materials storage management, which is conducive to reducing the loss of Chinese medicinal materials; by calculating the mold loss rate of the unit and analyzing the failure of the mildew inhibitor in the storage environment, it is convenient to promptly remind the staff to add a certain amount of mildew inhibitor to the storage environment, thereby effectively reducing the loss of medicinal materials and reducing unnecessary waste of resources. It can automatically adjust and optimize according to different storage conditions and medicinal material characteristics, reduce unnecessary waste of resources, thereby effectively reducing the loss of medicinal materials and improving the efficiency and accuracy of modern Chinese medicinal materials storage management.

[0063] 3. Since some Chinese medicinal materials are still biologically active during storage and can release or absorb carbon dioxide in the storage unit, and too high or too low carbon dioxide content has different effects on the growth of different types of mold, the ventilation duration is further adjusted by detecting the carbon dioxide content. By comprehensively monitoring the changes in environmental factors such as temperature and humidity, mold content, and carbon dioxide content, the ventilation duration can be flexibly adjusted. It can comprehensively consider different environmental factors, automatically adjust and optimize according to different storage conditions and medicinal material characteristics, identify and warn of potential environmental safety issues in advance, accurately control the ventilation process, and reduce unnecessary waste of resources, thereby effectively reducing the loss of medicinal materials and improving the efficiency and accuracy of modern Chinese medicinal materials storage management.

[0064] 4. If the ventilation time of the unit is zero, it means that the Chinese medicinal materials in the unit are usually sealed and packaged, so ventilation is not required. Only packaging damage detection is required. By obtaining the temperature and humidity change curves of the unit in one detection cycle and the previous detection cycle, and calculating the Pearson correlation coefficient, if the absolute value of the correlation coefficient is less than 0.5, it means that the temperature and humidity changes in the unit environment are abnormal, which is usually caused by packaging failure or damage. At this time, an alarm is sent to the management end to remind the staff to check the storage situation of the Chinese medicinal materials in the unit in time and replace the packaging in time. This setting can accurately control the ventilation process, reduce unnecessary waste of resources, and reduce cross-contamination, thereby effectively reducing the loss of medicinal materials and improving the efficiency and accuracy of modern Chinese medicinal materials storage management.

[0085] The Chinese medicinal materials are classified and stored according to the storage units. The acquisition module I obtains the storage requirements of the Chinese medicinal materials in each storage unit and sets the optimal storage conditions of the unit. The analysis module I monitors and obtains the storage environment of each unit, and grasps and records the environmental data such as temperature and humidity of each unit in real time. The judgment module I compares the temperature and humidity data with the optimal storage conditions, and can dynamically identify which units' environments do not meet the requirements, and warn of potential environmental problems in advance.

[0086] When the judgment module I monitors that the temperature and humidity data of one of the units do not meet the optimal temperature and humidity, the judgment module I transmits a signal to the adjustment module I, and the adjustment module I adjusts the temperature and humidity in the storage environment of the unit to the optimal temperature and humidity, and makes precise adjustments according to the storage requirements of the Chinese medicinal materials in the unit. The unit can selectively undergo humidification, dehumidification, insulation or low-temperature drying operations, thereby effectively reducing the loss of medicinal materials and improving the efficiency and accuracy of modern Chinese medicinal materials storage management.

[0087] When the judgment module II monitors that the difference between the last ventilation time and the current time of one of the units is greater than or equal to one ventilation cycle, that is, after the unit reaches the current ventilation time, if the ventilation time of the unit is not zero, the temperature and humidity change curve in the outdoor environment is obtained by the analysis module II, and the current ventilation time of the nth unit is adjusted according to the temperature and humidity change curve;

[0088] The analysis module III obtains the first mold content of the unit. If it is higher than the upper limit of the mold content, an alarm is issued to the management end. Since special types of Chinese medicinal materials carry molds or emit spores, the upper limit of the mold content is flexibly set according to the type of Chinese medicinal materials entered. The feedback module I dynamically identifies which units have abnormal storage environments or which units have deteriorated Chinese medicinal materials, thereby improving the efficiency and accuracy of Chinese medicinal materials storage management, which is conducive to reducing the loss of Chinese medicinal materials.

[0089] Since some Chinese medicinal materials still have biological activity during storage and can release or absorb carbon dioxide in the storage unit, and too high or too low carbon dioxide content has different effects on the growth of different types of molds, the carbon dioxide content is obtained through the analysis module III, and the feedback module II further adjusts the ventilation time according to the carbon dioxide content. By comprehensively monitoring the changes in environmental factors such as temperature and humidity, mold content, and carbon dioxide content, the adjustment module II flexibly adjusts the ventilation time. This method has strong dynamic adaptability, can comprehensively consider different environmental factors, and automatically adjust and optimize according to different storage conditions and medicinal material characteristics. It can cope with changing storage conditions, is conducive to early identification and early warning of potential environmental safety issues, accurately control the ventilation process, and reduce unnecessary waste of resources, thereby effectively reducing the loss of medicinal materials and improving the efficiency and accuracy of modern Chinese medicinal materials storage management.

[0090] The calculation module obtains the second mold content in the storage environment of the unit after ventilation is stopped, and analyzes the failure of the anti-mold agent in the storage environment by calculating the mold loss rate of the unit, so as to promptly remind the staff to add a certain amount of anti-mold agent to the storage environment, thereby effectively reducing the loss of medicinal materials and reducing unnecessary waste of resources.

[0091] If the ventilation time of the unit is zero, it means that the Chinese medicinal materials in the unit are usually sealed and packaged, so ventilation is not required. Only package damage detection is required. The temperature and humidity change curves of the unit in one detection cycle and the previous detection cycle are obtained through the damage detection module, and the Pearson correlation coefficient is calculated. If the absolute value of the correlation coefficient is less than 0.5, it means that the temperature and humidity changes in the unit environment are abnormal, which is usually caused by packaging failure or damage. At this time, an alarm is sent to the management end to remind the staff to check the storage situation of the Chinese medicinal materials in the unit in time, replace the packaging in time, reduce cross contamination, and effectively reduce the loss of medicinal materials.

[0092] Embodiment 2: A method for monitoring storage of Chinese medicinal materials based on scene analysis, comprising the following steps:

[0093] S1. Obtaining data I: There are N units in the storage area. Obtain the type and storage requirements of the Chinese medicinal materials entered in each unit, and set the optimal storage conditions of the corresponding unit. The optimal storage conditions include optimal temperature and humidity, ventilation cycle, and ventilation duration;

[0094] S2, scenario analysis I: monitor and obtain the temperature and humidity data in the storage environment of N units, compare the temperature and humidity data of N units with the optimal temperature and humidity in turn, and analyze whether the current environment meets the storage requirements of Chinese medicinal materials;

[0095] S3, judgment I: if the temperature and humidity data of the nth unit do not meet the optimal temperature and humidity, perform adjustment step I, otherwise, perform judgment step II, where n = 1, 2, ..., N;

[0096] S4, adjustment I: adjusting the temperature and humidity in the storage environment of the nth unit to the optimal temperature and humidity;

[0097] S5, judgment II: obtain the difference between the last ventilation time and the current time in the storage environment of the nth unit, if the difference of the unit is greater than or equal to one ventilation cycle, execute the scene analysis II step, otherwise, execute the scene analysis I step;

[0098] S6, scene analysis II: obtaining a temperature and humidity change curve in the outdoor environment. If the ventilation time of the nth unit is not zero, the current ventilation time of the nth unit is adjusted according to the temperature and humidity change curve. Otherwise, the damage detection step is performed.

[0099] S7, scenario analysis III: according to the type of Chinese medicinal materials entered in the nth unit, obtain the corresponding upper limit of mold content, obtain the mold content and carbon dioxide content in the storage environment of the nth unit, and record them as the first mold content;

[0100] S8, feedback I: if the first mold content of the nth unit is greater than or equal to the upper limit of the mold content, an alarm is sent to the management end, otherwise, feedback II step is executed;

[0101] S9, Feedback II: Make a secondary adjustment to the ventilation time of the nth unit according to the carbon dioxide content.

[0102] S10, Adjustment II: Ventilate the unit according to the adjusted ventilation time. When the ventilation time is reached, stop ventilation and record the ventilation time.

[0103] S11. Calculation: Obtain the mold content in the storage environment of the nth unit after ventilation is stopped, record it as the second mold content, calculate the mold loss rate = (first mold content - second mold content) / duration of this ventilation, and add a certain amount of mildew inhibitor to the storage environment of the nth unit according to the mold loss rate.

[0104] S12, damage detection: set the detection cycle to T, obtain the temperature and humidity change curve of the storage environment of the nth unit in a detection cycle, and calculate the Pearson correlation coefficient with the temperature and humidity change curve of the previous detection cycle. If the absolute value of the correlation coefficient is less than 0.5, an alarm is issued to the management end.

[0105] The working principle of this embodiment is:

[0106] Chinese medicinal materials are classified and stored according to storage units. By obtaining the storage requirements of Chinese medicinal materials in each storage unit, the optimal storage conditions of the unit are set. By monitoring and obtaining the storage environment of each unit, the environmental data such as temperature and humidity of each unit can be mastered and recorded in real time. By comparing the temperature and humidity data with the optimal storage conditions, it is possible to dynamically identify which units' environments do not meet the requirements and provide early warning of potential environmental problems.

[0107] When the temperature and humidity data of one of the monitored units do not meet the optimal temperature and humidity, the temperature and humidity in the storage environment of the unit will be adjusted to the optimal temperature and humidity, and precise adjustments will be made according to the storage requirements of the Chinese medicinal materials in the unit. The unit can be selectively humidified, dehumidified, kept warm or dried at low temperatures, thereby effectively reducing the loss of medicinal materials and improving the efficiency and accuracy of modern Chinese medicinal materials storage management.

[0108] When it is monitored that the difference between the last ventilation time and the current time of one of the units is greater than or equal to one ventilation cycle, that is, after the unit reaches the current ventilation time, if the ventilation time of the unit is not zero, by obtaining the temperature and humidity change curve in the outdoor environment, the current ventilation time of the nth unit is adjusted according to the temperature and humidity change curve;

[0109] The first mold content of the unit is obtained. If it is higher than the upper limit of the mold content, an alarm is sent to the management end. Since special types of Chinese medicinal materials carry mold or emit spores, the upper limit of the mold content is flexibly set according to the type of Chinese medicinal materials entered, so as to dynamically identify which units have abnormal storage environments or which units have deteriorated Chinese medicinal materials, thereby improving the efficiency and accuracy of Chinese medicinal materials storage management, which is conducive to reducing the loss of Chinese medicinal materials.

[0110] Since some Chinese medicinal materials are still biologically active during storage and can release or absorb carbon dioxide in the storage unit, and too high or too low carbon dioxide content has different effects on the growth of different types of mold, the ventilation duration is further adjusted by detecting the carbon dioxide content. By comprehensively monitoring the changes in environmental factors such as temperature and humidity, mold content, and carbon dioxide content, the ventilation duration can be flexibly adjusted. This method has strong dynamic adaptability, can comprehensively consider different environmental factors, and automatically adjust and optimize according to different storage conditions and medicinal material characteristics. It can cope with changing storage conditions, is conducive to early identification and warning of potential environmental safety issues, accurately control the ventilation process, and reduce unnecessary waste of resources, thereby effectively reducing the loss of medicinal materials and improving the efficiency and accuracy of modern Chinese medicinal materials storage management.

[0111] The second mold content in the storage environment of the unit after ventilation is stopped is obtained, and the mold loss rate of the unit is calculated to analyze the failure of the anti-mold agent in the storage environment, so as to promptly remind the staff to add a certain amount of anti-mold agent to the storage environment, thereby effectively reducing the loss of medicinal materials and reducing unnecessary waste of resources.

[0112] If the ventilation time of the unit is zero, it means that the Chinese medicinal materials in the unit are usually sealed and packaged, so ventilation is not required. Only packaging damage detection is required. By obtaining the temperature and humidity change curves of the unit in one detection cycle and the previous detection cycle, and calculating the Pearson correlation coefficient, if the absolute value of the correlation coefficient is less than 0.5, it means that the temperature and humidity changes in the unit environment are abnormal, which is usually caused by packaging failure or damage. At this time, an alarm is sent to the management end to remind the staff to check the storage situation of the Chinese medicinal materials in the unit in time, replace the packaging in time, reduce cross contamination, and effectively reduce the loss of medicinal materials.

[0113] The above disclosure is only a specific embodiment of the present invention, but the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
