Description

Technical Field

[0001] The invention belongs to the field of temperature control, and relates to a temperature control method and a system for a chemical storage cabinet. Background Art

[0002] The quality and effectiveness of chemical drugs, especially those that are temperature-sensitive, such as certain biological agents, vaccines, enzymes, antibodies, etc., largely depend on the stability and accuracy of storage temperature. Too high or too low a temperature may cause the drug to deteriorate, become ineffective, or even produce harmful side effects. Therefore, for the storage of such drugs, a system that can precisely control the temperature is required to ensure its safety and effectiveness during long-term storage.

[0003] For example, the Chinese invention with publication number CN118585011A discloses an artificial intelligence-based temperature control method for an electric control cabinet, which includes: collecting temperatures at different locations at different times, obtaining the importance of each temperature sensor inside the electric control cabinet through the correlation between the temperature sensors inside the electric control cabinet, the correlation with the target control temperature, the abnormality of the temperature sensor, and the temperature distribution characteristics and significant characteristics of the temperature sensor; determining the importance of obtaining external temperature sensors through the temperature difference and correlation between the outside and inside of the electric control cabinet, selecting sensors with high importance based on the importance of the inside and outside, and determining the target control temperature based on this, and controlling the equipment through the target control temperature. This application controls the temperature of the temperature control equipment to the final target control temperature, thereby ensuring the safety of the electric control cabinet.

[0004] The above existing technologies have the following problems: 1. It is often difficult for existing technologies to monitor the temperature conditions in chemical storage cabinets in real time and respond in a timely manner. When the temperature in the storage cabinet does not meet the requirements, it is impossible to immediately detect and initiate corresponding control measures according to the dynamic changes in the external environment, resulting in the drugs being exposed to inappropriate temperatures for too long, increasing the risk of drug deterioration and failure.

[0005] 2. The existing technology is unable to monitor the temperature unevenness in the chemical storage cabinet in real time, and then adjust the distance from the internal partition to the cabinet wall to improve air circulation to achieve the temperature control effect, resulting in uneven heating of some drugs, affecting their stability and shelf life. In addition, drugs that are exposed to unsuitable temperatures for a long time may undergo chemical changes, resulting in reduced efficacy or the production of harmful substances.

[0013] Temperature compliance determination module: used to determine whether the temperature inside the chemical storage cabinet complies based on the temperature compliance inside the chemical storage cabinet.

[0014] External environment control module: when the temperature inside the chemical storage cabinet does not meet the requirements, it collects the temperature of the external environment where the chemical storage cabinet is located, analyzes the temperature deviation coefficient of the external environment where the chemical storage cabinet is located, and sets the target control temperature inside the chemical storage cabinet.

[0015] Temperature uniformity analysis module: used to collect the temperature of each temperature-uniformly distributed area in the chemical storage cabinet at each set collection point, analyze the influence coefficient of the temperature corresponding to a set unit distance of each temperature-uniformly distributed area in the chemical storage cabinet, and then analyze the target control distance between the internal partition and the cabinet wall of each temperature-uniformly distributed area in the chemical storage cabinet for adjustment.

[0016] Temperature uniformity adjustment module: used to collect the temperature of each temperature-uniformly distributed area in the chemical storage cabinet at each set collection point, analyze the temperature influence coefficient of each temperature-uniformly distributed area in the chemical storage cabinet, and then analyze the target control distance between the internal partition and the cabinet wall of each temperature-uniformly distributed area in the chemical storage cabinet for adjustment.

[0017] Database: for the suitable temperature range and specific heat capacity of each chemical, and for storing the thermal conductivity, total surface area and thickness of the walls of the chemical storage cabinets.

The temperature conditions of various areas in the chemical storage cabinet can be accurately understood. For areas with uneven temperature distribution, timely measures can be taken to analyze them to ensure that each area can provide a suitable and stable temperature environment for the drugs. This helps to maintain the chemical stability of the drugs and prevent the occurrence of quality problems such as drug deterioration, decomposition or reduced efficacy due to local temperature abnormalities.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1As shown, the present invention provides a temperature control method for a chemical storage cabinet, the method comprising: S1, temperature compliance analysis: dividing the chemical storage cabinet into various areas based on internal partitions in the chemical storage cabinet, collecting the temperature of each area in the chemical storage cabinet, and analyzing the temperature compliance in the chemical storage cabinet.

[0027] The suitable temperature range of each chemical is extracted from the database, the type of chemical is identified according to the barcode of the chemical stored in the chemical storage cabinet, and the suitable temperature range of the chemical is screened out from the suitable temperature ranges of each chemical based on the type of the chemical.

[0029] The present invention divides the chemical storage cabinet into various areas based on the internal partitions in the chemical storage cabinet, collects the temperature of each area in the chemical storage cabinet, and analyzes the temperature compliance in the chemical storage cabinet. It can realize refined monitoring of the temperatures at different positions in the storage cabinet, which helps to more accurately understand whether the temperature environment of each area meets the appropriate temperature range for storing corresponding drugs, thereby ensuring that the drugs are always under the optimal storage temperature conditions and reducing the occurrence of quality problems such as drug deterioration and failure due to inappropriate temperature.

[0030] S2. Temperature compliance determination: Determine whether the temperature in the chemical storage cabinet complies based on the temperature compliance in the chemical storage cabinet.

[0031] Furthermore, the specific process of determining whether the temperature inside the chemical storage cabinet complies is: comparing the temperature compliance inside the chemical storage cabinet with a preset temperature compliance threshold; if the temperature compliance inside the chemical storage cabinet is less than the preset temperature compliance threshold, then the temperature inside the chemical storage cabinet does not comply.

[0032] The present invention determines whether the temperature in the chemical storage cabinet complies based on the temperature compliance in the chemical storage cabinet, thereby providing a basis for determining the temperature in the chemical storage cabinet based on the temperature of the environment in which the chemical storage cabinet is located, thereby minimizing the adverse temperature effects on the drugs during storage, thereby extending the shelf life of the drugs, reducing the situation where the drugs are scrapped due to expiration, and reducing the storage costs of the drugs.

[0033] S3. External environment control: When the temperature inside the chemical storage cabinet does not meet the requirements, the temperature of the external environment where the chemical storage cabinet is located is collected, the temperature deviation coefficient of the external environment where the chemical storage cabinet is located is analyzed, and the target control temperature inside the chemical storage cabinet is set.

[0034] Furthermore, the specific process of analyzing the temperature and humidity influencing factors of the external environment of the chemical storage cabinet is as follows: the temperature of the external environment of the chemical storage cabinet is collected by a temperature sensor, and the temperature of each area in the chemical storage cabinet is substituted into the average calculation formula to obtain the temperature in the chemical storage cabinet, which is recorded as T inside .

[0035] The thermal conductivity, total surface area and thickness of the cabinet wall of the chemical storage cabinet are extracted from the database and denoted as k, A and Δx respectively.

[0036] The specific heat capacity of each chemical is extracted from the database, and the specific heat capacity of the chemical is screened out from the specific heat capacity of each chemical based on the type of the chemical.

[0037] Count the number of chemicals in the chemical storage cabinet, multiply the specific heat capacity of the chemicals by the number of chemicals, and obtain the total specific heat capacity of the chemicals in the chemical storage cabinet, recorded as C.

[0038] The mass of each chemical in the chemical storage cabinet is measured by an electronic balance, and the mass is summed up to obtain the total mass of the chemicals in the chemical storage cabinet, which is recorded as M.

[0039] Analyze the temperature deviation coefficient χ of the external environment of the chemical storage cabinet. Where ΔT′ represents the temperature change of the external environment of the chemical storage cabinet on the internal environment. Q represents the heat transferred from the external environment of the chemical storage cabinet to the internal environment. T max and T min Respectively represent the maximum and minimum temperature values ​​in the suitable temperature range of chemicals, T out Indicates the temperature of the environment where the chemical storage cabinet is located.

[0040] Furthermore, the specific formula for setting the target control temperature in the chemical storage cabinet is:

[0041]

[0042] The present invention collects the temperature of the external environment in which the chemical storage cabinet is located, analyzes the temperature deviation coefficient of the external environment in which the chemical storage cabinet is located, and sets the target control temperature in the chemical storage cabinet when the temperature in the chemical storage cabinet does not meet the requirements. The present invention can respond in real time and accurately control the temperature to ensure that the chemical drugs are stored under optimal temperature conditions, thereby reducing the risk of drug deterioration and failure. This helps to improve the safety and efficacy of patients' medication, and can significantly reduce the operating costs of hospitals by reducing drug losses caused by temperature non-compliance. At the same time, intelligent temperature control can also reduce manual intervention and reduce management costs.

[0043] S4. Temperature uniformity analysis: Collect the temperatures of various temperature-uniform distribution areas in the chemical storage cabinet at the set collection points, analyze the influence coefficient of the temperature corresponding to a set unit distance of each temperature-uniform distribution area in the chemical storage cabinet, and then analyze the target control distance between the internal partition and the cabinet wall of each temperature-uniform distribution area in the chemical storage cabinet for adjustment.

[0044] Furthermore, the specific process of analyzing the temperature distribution uniformity index of each area in the chemical storage cabinet after temperature control is as follows: the temperature of each area in the chemical storage cabinet after temperature control at each set collection point is collected by a temperature sensor, which is recorded as Ctem qi , where i represents the number corresponding to the i-th collection point, i=1, 2, 3, ...I.

[0045] The distance between the center point of each area in the chemical storage cabinet and the center point of the temperature control device and the distance between the center point of the temperature control device and the center point of the bottom of the chemical storage cabinet are obtained by a laser rangefinder.

[0046] The distance influence factor of each area in the chemical storage cabinet is obtained by dividing the distance from the center point of each area in the chemical storage cabinet to the center point of the temperature control device by the distance between the center point of the temperature control device and the center point of the bottom of the chemical storage cabinet.

[0047] Multiply the distance influence factor of each area in the chemical storage cabinet by the target control temperature in the chemical storage cabinet to obtain the target temperature of each area in the chemical storage cabinet, which is recorded as Ztem q .

[0048] Analyze the temperature distribution uniformity index of each area in the chemical storage cabinet after temperature control q , Where I represents the total number of collection points in the area of ​​the chemical storage cabinet, and t0 represents the set temperature.

[0049] As a preferred embodiment, the t0 can be set to 0.5.

[0050] Furthermore, the specific process of judging whether the temperature of each area in the chemical storage cabinet after temperature control is uniformly distributed is: comparing the temperature distribution uniformity index of each area in the chemical storage cabinet after temperature control with the preset temperature distribution uniformity index; if the temperature distribution uniformity index of a certain area in the chemical storage cabinet after temperature control is less than the preset temperature distribution uniformity index, the temperature distribution of the area in the chemical storage cabinet after temperature control is uneven, and then the uneven temperature distribution areas in the chemical storage cabinet are screened out.

[0051] The present invention collects the temperatures of various areas in the chemical storage cabinet after temperature control at various set collection points, analyzes the temperature distribution uniformity index of various areas in the chemical storage cabinet after temperature control, determines whether the temperatures of various areas in the chemical storage cabinet are evenly distributed, and then screens out various areas with uneven temperature distribution in the chemical storage cabinet. The temperature conditions of various areas in the chemical storage cabinet can be accurately understood, and for areas with uneven temperature distribution, timely measures can be taken to analyze to ensure that each area can provide a suitable and stable temperature environment for the drugs, which helps to maintain the chemical stability of the drugs and prevent the occurrence of quality problems such as drug deterioration, decomposition or reduced efficacy due to local temperature abnormalities.

[0052] S5. Temperature uniformity adjustment: Collect the temperatures of various temperature-uniform distribution areas in the chemical storage cabinet at the set collection points, analyze the temperature influence coefficients of various temperature-uniform distribution areas in the chemical storage cabinet, and then analyze the target control distance between the internal partitions and the cabinet wall of various temperature-uniform distribution areas in the chemical storage cabinet for adjustment.

[0053] Furthermore, the specific process of analyzing the temperature influence coefficient of each temperature-unevenly distributed area in the chemical storage cabinet is as follows: traverse the temperature of each temperature-unevenly distributed area in the chemical storage cabinet at each set collection point, obtain the highest temperature and the lowest temperature of each temperature-unevenly distributed area in the chemical storage cabinet at the set collection point, make a difference between the highest temperature and the lowest temperature, and obtain the maximum temperature difference of each temperature-unevenly distributed area in the chemical storage cabinet, recorded as ΔW u , where u represents the number corresponding to the u-th temperature uneven distribution area in the chemical storage cabinet, u = 1, 2, 3, ... U;

[0054] The length and width of each temperature-uneven distribution region in the chemical storage cabinet are obtained by a laser rangefinder, and the length and width are multiplied to obtain the area of ​​each temperature-uneven distribution region in the chemical storage cabinet;

[0055] The number of drugs in each temperature-uneven distribution area in the chemical storage cabinet is counted, and the number of drugs in each temperature-uneven distribution area in the chemical storage cabinet is divided by the area of ​​the corresponding area to obtain the distribution density of drugs in each temperature-uneven distribution area in the chemical storage cabinet, which is recorded as ψ u ;

[0056] Analyze the temperature influence coefficient of each area with uneven temperature distribution in the chemical storage cabinet. Among them, ΔW′ and ψ′ represent the maximum allowable temperature difference of the area in the chemical storage cabinet and the allowable distribution density of the drugs, respectively, θ1 and θ2 represent the weights corresponding to the maximum temperature difference of the area in the chemical storage cabinet and the distribution density of the drugs, respectively, and θ1+θ2=1.

[0057] As a preferred embodiment, θ1 and θ2 can be set to 0.7 and 0.3 respectively. For many chemical drugs, their stability often has strict requirements on the storage temperature. Slight changes in temperature may cause the drugs to deteriorate, fail, etc., seriously affecting the quality and safety of the drugs. In contrast, although the distribution density of drugs will also have a certain impact on the storage environment, its impact may be slightly less than that of temperature factors. Therefore, the weight corresponding to the maximum temperature difference of the area in the chemical storage cabinet is greater than the weight corresponding to the distribution density of the drugs.

[0058] Furthermore, the specific process of analyzing the target control distance between the internal partitions and the cabinet walls of each area with uneven temperature distribution in the chemical storage cabinet is: setting a relationship function between the control distance between the internal partitions and the cabinet walls of the area in the chemical storage cabinet and the temperature influence coefficient, substituting the temperature influence coefficient of each area with uneven temperature distribution in the chemical storage cabinet into the relationship function between the control distance between the internal partitions and the cabinet walls of the area in the chemical storage cabinet and the temperature influence coefficient, and obtaining the target control distance between the internal partitions and the cabinet walls of each area with uneven temperature distribution in the chemical storage cabinet.

[0059] As a preferred embodiment, the preset relationship function is manually entered and set by the chemical storage management personnel into the database for storage. The larger the temperature influence coefficient, the longer the control distance between the internal partition of the area and the cabinet wall needs to be adjusted, thereby improving the air circulation in the area inside the chemical storage cabinet, and further regulating the temperature of the area inside the chemical storage cabinet.

[0060] The relationship function between the set control distance between the internal partition and the cabinet wall in the area inside the chemical storage cabinet and the temperature influence coefficient is a linear function.

[0061] The specific process of the adjustment is: if the distance between the internal partition and the cabinet wall in the area inside the chemical storage cabinet is the same as the target control distance, no adjustment is performed; if the distance between the internal partition and the cabinet wall in the area inside the chemical storage cabinet is different from the target control distance, the distance between the internal partition and the cabinet wall in the area inside the chemical storage cabinet is adjusted to the target control distance.

[0062] The present invention collects the temperatures of various temperature-unevenly distributed areas in the chemical storage cabinet at various set collection points, analyzes the temperature influence coefficients of various temperature-unevenly distributed areas in the chemical storage cabinet, and further analyzes the target control distances between the internal partitions and the cabinet walls of various temperature-unevenly distributed areas in the chemical storage cabinet. Adjustment is performed to improve the air circulation in the chemical storage cabinet, prevent uneven heating of some medicines, ensure that the chemicals are always in a suitable storage temperature environment, extend their shelf life, and reduce the occurrence of drug failure due to temperature factors.
