Description

Technical Field

[0001] This invention relates to the field of medicine management cabinets, specifically to an internal environment monitoring and early warning system for medicine management cabinets. Background Technology

[0002] The efficacy and safety of pharmaceuticals, especially vaccines, biological agents, and precision chemicals, are highly dependent on the stability of the storage environment. As the core storage equipment in medical institutions, laboratories, pharmacies, and other places, the precise control of the internal environment of the medicine management cabinet is crucial, mainly including multiple parameters such as temperature, humidity, and light.

[0003] Currently, the technology of medicine management cabinets on the market has evolved from passive insulation to active control. Most advanced medicine management cabinets are equipped with built-in temperature and humidity sensors, which can monitor the environment inside the cabinet in real time and issue alarms or activate cooling / dehumidification equipment to intervene when parameters exceed preset fixed thresholds.

[0004] Therefore, although certain safeguards are provided for drug storage, conventional systems mainly adopt a passive response mode of "monitoring-exceeding limits-regulation". When cabinet doors are frequently opened, the external environment changes drastically, or a large number of new drugs are stored, the internal environment will first experience a fluctuation process, and the system will then make compensation adjustments. This lag may cause drugs to be exposed to unsuitable environments in a short period of time, which may pose a quality risk.

[0005] At the same time, it lacks foresight and initiative, and cannot predict the changes in heat load and moisture load caused by frequent access to medicines or the quantity and characteristics of medicines accessed at one time based on historical data. Therefore, it is impossible to start the adjustment system in advance to counteract these disturbances. For this reason, the present invention proposes a solution. Summary of the Invention

[0006] This invention utilizes a multi-dimensional comprehensive analysis of internal environmental parameters, drug storage parameters, and external environmental parameters to enable the drug management cabinet to formulate more precise and dynamic adjustment strategies, providing a continuous, stable, and high-quality storage environment for drugs. Simultaneously, by analyzing interference from drug access behavior and combining it with external environmental parameters, it predicts potential future environmental disturbances and generates pre-adjustment instructions. This allows the drug management cabinet to proactively adjust before environmental fluctuations occur, reserving a fluctuation range for the environmental parameters within the cabinet and preventing drugs from being frequently exposed to unsuitable environments for short periods. This addresses the technical deficiencies of the prior art and proposes an internal environmental monitoring and early warning system for drug management cabinets.

[0007] The objective of this invention can be achieved through the following technical solution: an internal environment monitoring and early warning system for a medicine management cabinet, including an internal environment monitoring module, wherein the internal environment monitoring module is used to collect internal environment information of the medicine management cabinet and obtain internal environment parameters;

[0008] The internal material management module can scan the medicine materials stored in the medicine management cabinet, obtain medicine information, and search the database based on the medicine information to obtain the corresponding storage parameters.

[0009] An external environment detection module is used to detect the external environment of the medicine management cabinet, obtain the ambient temperature and humidity, and record them as external environment parameters.

[0010] The integrated control module obtains internal environmental parameters through the internal environment management module and storage parameters through the internal material management module. It then compares the internal environmental parameters with the storage parameters to generate internal environment adjustment instructions and adjust the internal environment.

[0011] The dynamic pre-adjustment module analyzes stored parameters to obtain the interference frequency and environmental interference amount, records them as pre-adjustment amounts, and sends the pre-adjustment amounts to the integrated control module.

[0012] The integrated control module obtains external environmental parameters through the external environment detection module and obtains pre-adjustment amounts through the dynamic pre-adjustment module. Based on the external environmental parameters and pre-adjustment amounts, it performs interference prediction and generates pre-adjustment instructions.

[0013] In a preferred embodiment of the present invention, the internal environment monitoring module collects internal environment information including internal temperature and internal humidity, and dynamically records the internal temperature and internal humidity acquired at different times to obtain the temperature dynamics and humidity dynamics that change over time.

[0014] In a preferred embodiment of the present invention, the internal environment monitoring module records the points where the temperature changes from rising to falling and the points where the temperature changes from falling to rising as temperature inflection points, and calculates the temperature difference between adjacent temperature inflection points. The group of temperature inflection points with a temperature difference less than a set threshold is deleted. After deletion, the above process is repeated until the temperature difference between all adjacent temperature inflection points is greater than or equal to the set threshold. The number of deleted inflection points is used as the frequency of temperature fluctuation.

[0015] The internal environment monitoring module analyzes the standard deviation and frequency of temperature fluctuations in temperature dynamics using formulas to obtain temperature fluctuation indicators.

[0016] In a preferred embodiment of the present invention, the internal environment monitoring module calculates the standard deviation of humidity dynamics and uses the standard deviation calculation result as a humidity fluctuation index. The internal environment monitoring module uses internal temperature, internal humidity, temperature fluctuation index and humidity fluctuation index as internal environment parameters.

[0017] In a preferred embodiment of the present invention, the internal material management module obtains the storage temperature and humidity corresponding to the medicines from the database, compares the storage temperature and humidity of all medicines stored in the medicine management cabinet, obtains the temperature range that can meet the storage temperature of all medicines, records it as the storage temperature range, and the humidity range that can meet the storage humidity of all medicines, records it as the storage humidity range, and records it in the storage parameters.

[0018] The internal material management module can also obtain the drug inventory warning via the network and compare the drugs in the drug management cabinet with the drug inventory warning of the same category. If the drug quantity is less than the drug inventory warning, a drug inventory warning is triggered, and the internal material management module also records the drug inventory warning in the storage parameters.

[0019] In a preferred embodiment of the present invention, the integrated control module compares the internal temperature and internal humidity with the storage temperature range and storage humidity range in the storage parameters. If the internal temperature exceeds the storage temperature range, a corresponding heating / cooling command is generated. If the internal humidity is outside the storage humidity range, a corresponding humidification / drying command is generated.

[0020] In a preferred embodiment of the present invention, after acquiring the temperature fluctuation index and the humidity fluctuation index, the integrated control module performs threshold judgment on the temperature fluctuation index and the humidity fluctuation index respectively, and determines that the temperature fluctuation is too large and the humidity fluctuation is too large based on the judgment result.

[0021] The integrated control module calculates the ambient temperature and internal temperature from the external environmental parameters to obtain the temperature difference ratio. If the temperature difference ratio is greater than the set threshold, a temperature control power boost signal is generated. If the temperature difference ratio is less than the set threshold, a pre-adjustment enhancement signal is generated. The module also calculates the ambient humidity and internal humidity to obtain the humidity difference ratio. If the humidity difference ratio is greater than the set threshold, a humidity control power boost signal is generated. If the humidity difference ratio is not greater than the set threshold, a pre-adjustment enhancement signal is generated.

[0022] After generating a temperature control power boosting signal, the integrated control module increases the heating / cooling power of the medicine management cabinet; after generating a humidity control boosting signal, it increases the drying / humidifying power of the medicine management cabinet.

[0023] In a preferred embodiment of the present invention, after the dynamic pre-adjustment module obtains the drug inventory warning, it generates an interference event. At the same time, the dynamic pre-adjustment module obtains the average number of times the drug management cabinet is opened within a day through historical data to obtain the basic interference frequency. The dynamic pre-adjustment module sums the basic interference frequency with the interference event to obtain the final interference frequency.

[0024] The dynamic pre-adjustment module calculates the difference between the ambient temperature and the storage temperature range, and the difference between the ambient humidity and the storage humidity range, to obtain the temperature interference difference and the humidity interference difference, and then sums them by weight allocation to obtain the environmental interference amount.

[0025] The dynamic pre-adjustment module records the amount and frequency of environmental interference as pre-adjustment values.

[0026] In a preferred embodiment of the present invention, after obtaining the pre-adjustment amount, the integrated control module generates pre-adjustment parameters through formula analysis. The two ends of the temperature range in the stored parameters are recorded as T1 and T2 respectively, and the final temperature control value Tb is obtained through the formula. Similarly, the two ends of the humidity range in the stored parameters are recorded as R1 and R2 respectively, and the final humidity control value Rb is obtained through the formula. The integrated control module uses the final humidity control value Rb and the final temperature control value Tb as pre-adjustment instructions.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. In this invention, by adding a dynamic pre-adjustment module, the system can analyze the interference of drug storage and retrieval behavior, and predict possible environmental disturbances in the future by combining external environmental parameters. Based on this, a pre-adjustment instruction is generated, so that the comprehensive control module can actively adjust before environmental fluctuations occur, stabilize environmental parameters within the target range, and reserve a fluctuation range in environmental parameter control in advance according to the interference of the drug management cabinet, thereby reducing the impact of drug storage and retrieval operations on the environment inside the drug management cabinet.

[0029] 2. In this invention, internal environmental parameters, drug-specific storage parameters, external environmental parameters, and predicted pre-adjustment amounts are comprehensively analyzed from multiple dimensions. The integrated control module can formulate more accurate and dynamic adjustment strategies, which greatly suppresses the fluctuation range and duration of environmental parameters, providing a continuous, stable, and high-quality storage environment for drugs.

[0030] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0031] Figure 1 This is a system block diagram of the present invention;

[0032] Figure 2 This is a system flowchart of the present invention. Detailed Implementation

[0033] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1 - Figure 2 As shown, the internal environment monitoring and early warning system of the medicine management cabinet includes an internal environment monitoring module, an internal material management module, an external environment detection module, a comprehensive control module, and a dynamic pre-adjustment module. The internal environment monitoring module obtains the internal temperature and humidity of the cabinet through multiple sensors located inside the medicine management cabinet, and dynamically records the internal temperature and humidity obtained at different times, thereby obtaining the temperature dynamics and humidity dynamics that change over time.

[0035] The internal environment monitoring module analyzes temperature dynamics and obtains the temperature fluctuation index TJ. Where F is the standard deviation of temperature fluctuation, f is the frequency of temperature fluctuation, and q is a preset weighting coefficient. The specific method for calculating the standard deviation F of temperature fluctuation is as follows: , where Ti is the temperature at different times in the temperature dynamic, t is the average of all temperatures in the temperature dynamic, and n is the number of temperature samples in the temperature dynamic;

[0036] The method for the internal environment monitoring module to obtain the frequency of temperature fluctuations is as follows: The internal environment monitoring module records the points in the temperature dynamics that change from heating to cooling and the points that change from cooling to heating as temperature inflection points, and deletes the micro inflection points. The number of inflection points after deletion is taken as the frequency of temperature fluctuations.

[0037] Specifically, the method for deleting micro inflection points is as follows: calculate adjacent temperature inflection points. If the temperature difference between adjacent temperature inflection points is less than the set threshold, then delete the latter group of the two adjacent temperature inflection points. After deletion, repeat the above process until the temperature difference between all adjacent temperature inflection points is greater than or equal to the set threshold.

[0038] The internal environment monitoring module dynamically acquires the humidity fluctuation index RJ based on humidity. , where Ry is the humidity value of different samples in the humidity dynamic, r is the average humidity in the humidity dynamic, and m is the number of samples;

[0039] The internal environment monitoring module sends internal temperature, internal humidity, temperature fluctuation indicators, and humidity fluctuation indicators to the integrated management and control module;

[0040] After obtaining the latest internal temperature and humidity, the integrated control module compares the internal temperature and humidity with the storage temperature range and storage humidity range in the storage parameters. If the internal temperature is within the storage temperature range, no response is made. If the internal temperature exceeds the storage temperature range, a corresponding heating / cooling command is generated. If the internal humidity is within the storage humidity range, no response is made. If the internal humidity is outside the storage humidity range, a corresponding humidification / drying command is generated.

[0041] The internal materials management module manages internal medicines through the barcode scanning device for entering and leaving the medicine management cabinet. After obtaining the medicine information, it searches the database to obtain the corresponding storage temperature and humidity for each medicine. The internal materials management module compares the storage temperature and humidity of all medicines stored in the medicine management cabinet to obtain the temperature range that meets the storage requirements of all medicines, and records the humidity range that meets the storage requirements of all medicines, which is recorded as the storage temperature range. Both are recorded in the storage parameters.

[0042] After acquiring the stored parameters, the integrated control module compares them with the latest internal temperature and internal humidity.

[0043] After acquiring the temperature fluctuation index and humidity fluctuation index, the integrated control module performs threshold judgment on the temperature fluctuation index and humidity fluctuation index respectively. If the temperature fluctuation index is greater than the set temperature fluctuation threshold, the temperature fluctuation is judged to be too large. If the temperature fluctuation index is not greater than the set temperature fluctuation threshold, the temperature fluctuation is judged to be normal. If the humidity fluctuation index is greater than the set humidity fluctuation threshold, the humidity fluctuation is judged to be too large. If the humidity fluctuation index is not greater than the set humidity fluctuation threshold, the humidity fluctuation is judged to be normal.

[0044] After receiving results indicating excessive humidity or temperature fluctuations, the integrated control module acquires external environmental parameters through the external environment detection module. It then calculates the temperature difference between the ambient and internal temperatures, and calculates the ratio of this temperature difference to the internal temperature to obtain the temperature difference ratio. If the temperature difference ratio is greater than a set threshold, a temperature control power boost signal is generated; if the temperature difference ratio is less than the set threshold, a pre-adjustment enhancement signal is generated. Similarly, the module calculates the humidity difference between the ambient and internal humidity, and calculates the humidity difference ratio by comparing the temperature difference with the internal humidity. If the humidity difference ratio is greater than a set threshold, a humidity control power boost signal is generated; if the humidity difference ratio is not greater than the set threshold, a pre-adjustment enhancement signal is generated.

[0045] After generating a temperature control power increase signal, the integrated control module increases the heating / cooling power of the medicine management cabinet; after generating a humidity control increase signal, it increases the drying / humidifying power of the medicine management cabinet.

[0046] Example 2: Please refer to Figure 1 - Figure 2 As shown, the internal material management module can also obtain the drug inventory warning via the network and compare the drugs in the drug management cabinet with the drug inventory warning of the same category. If the drug quantity is less than the drug inventory warning, a drug inventory warning is triggered. If the drug quantity is greater than the drug inventory warning, no reaction is made. The internal material management module also records the drug inventory warning in the storage parameters.

[0047] The external environment detection module acquires the ambient temperature and humidity outside the medicine management cabinet through temperature and humidity sensors, records them as external environment parameters, and sends the external environment parameters to the integrated control module.

[0048] After obtaining the drug inventory warning from the stored parameters through the internal material management module, the dynamic pre-adjustment module generates an interference event. At the same time, the dynamic pre-adjustment module obtains the number of times the drug management cabinet is opened in a day through historical data, and calculates the average of the data over multiple days to obtain the basic interference frequency. The dynamic pre-adjustment module sums the basic interference frequency with the interference events to obtain the final interference frequency.

[0049] The dynamic pre-adjustment module compares external environmental parameters with storage parameters, calculates the difference between the ambient temperature and storage temperature range, and the ambient humidity and storage humidity range, obtains the temperature interference difference and humidity interference difference, and sums them through weight allocation to obtain the environmental interference amount.

[0050] The dynamic pre-adjustment module records the amount and frequency of environmental interference as pre-adjustment values;

[0051] After obtaining the pre-adjustment amount, the integrated control module generates the pre-adjustment parameter Adv through formula analysis. Where adj is the pre-adjustment amount, after the integrated control module obtains the pre-adjustment parameter Adv, it records the two extreme values ​​of the temperature range stored in the parameter as T1 and T2 respectively, and then uses the formula... To obtain the final temperature control value Tb, similarly, record the two ends of the humidity range in the stored parameters as R1 and R2, respectively, and then obtain the final humidity control value Rb using the formula. The integrated control module uses the final humidity control value Rb and the final temperature control value Tb as pre-adjustment instructions.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation.
