Technical Field
[0001] The present application relates to the field of cold chain transportation technology, and in particular to a temperature monitoring method, product, equipment and medium during the transportation of medicines. Background Art
[0002] In the field of pharmaceutical transportation, it is crucial to ensure the temperature stability of the drugs throughout the transportation process, because many drugs are very sensitive to temperature, and exceeding a certain temperature range may cause the drugs to lose effectiveness, deteriorate, or even become ineffective.
[0003] The relevant technology monitors and adjusts the temperature through preset temperature control equipment such as refrigerated trucks and insulated boxes. Although it can maintain temperature stability to a certain extent, it lacks flexibility and dynamic adjustment capabilities and cannot adapt to various changes that may occur during transportation, such as ambient temperature fluctuations, extended transportation time, etc., resulting in inaccurate temperature monitoring during transportation. Summary of the invention
[0004] In order to improve the accuracy of temperature monitoring during drug transportation, the present application provides a temperature monitoring method, product, equipment and medium during drug transportation.
[0005] In the first aspect, the present application provides a method for temperature monitoring during drug transportation, which adopts the following technical solution: A method for monitoring temperature during drug transportation, comprising: Obtain the category of medicines transported in the cold chain turnover box at the current moment, as well as multiple temperatures at different locations in the cold chain turnover box; Determine a transportation temperature range corresponding to the drug category, and compare the multiple temperatures with the transportation temperature range respectively; If the multiple temperatures do not exceed the transport temperature range, calculating an average value of the multiple temperatures as the target temperature; The target temperature data containing the target temperature in the cold chain turnover box during this transportation process is obtained, and the refrigeration power of the refrigeration system of the cold chain turnover box is adjusted according to the target temperature data.
[0006] By adopting the above technical solution, the drug category and the temperature of different positions in the box can be obtained in real time. Multi-point temperature monitoring can provide more comprehensive temperature data, which is helpful to more accurately evaluate the temperature distribution in the box and reduce the error that may be caused by a single monitoring point. Comparing the measured temperature with the temperature range required for drug transportation can ensure that the drug is always within the specified temperature range during the entire transportation process, thereby ensuring the quality and safety of the drug. The use of average values can reduce misjudgments caused by single-point temperature fluctuations and improve the stability and reliability of temperature control. The refrigeration power of the refrigeration system is dynamically adjusted according to the target temperature data obtained in real time, which can ensure that the temperature in the cold chain turnover box is always maintained at the optimal state. Dynamic adjustment of the refrigeration power can not only ensure the quality of the drug, but also effectively reduce energy consumption and improve the energy efficiency of cold chain transportation. It realizes the automatic management and control of the temperature of the cold chain turnover box, reduces manual intervention, and improves management efficiency and accuracy.
[0007] In a preferred example, the present application may be further configured as follows: adjusting the refrigeration power of the refrigeration system of the cold chain turnover box according to the target temperature data includes: Determining a target temperature range according to the transport temperature range, wherein a lower limit temperature of the target temperature range is higher than a lower limit temperature of the transport temperature range, and an upper limit temperature of the target temperature range is lower than an upper limit temperature of the transport temperature range; comparing the target temperature with the target temperature range; If the target temperature reaches the upper limit temperature or the lower limit temperature of the target temperature range, the refrigeration power of the refrigeration system of the cold chain turnover box is adjusted according to the target temperature data.
[0008] By adopting the above technical solution, a target temperature range narrower than the transportation temperature range is set, which provides an additional safety buffer for drug transportation and helps ensure that the drugs can be kept within the ideal temperature range even under slight temperature fluctuations. Once the target temperature is found to be close to or reaches the boundary of the target temperature range, the system can respond immediately to prevent the temperature from exceeding the transportation temperature range. When the target temperature approaches the upper limit, the refrigeration power is increased to prevent overheating; when it approaches the lower limit, the refrigeration power is reduced to prevent overcooling.
[0009] In a preferred example, the present application may be further configured as follows: adjusting the refrigeration power of the refrigeration system of the cold chain turnover box according to the target temperature data includes: Determine the comprehensive change in heat in the cold chain turnover box per unit time according to the target temperature data; Acquire a current refrigeration power of the refrigeration system, and determine a first refrigeration capacity of the refrigeration system per unit time at the current refrigeration power; Determine the amount of heat absorption according to the comprehensive change in heat and the first refrigeration capacity, where the amount of heat absorption represents the amount of heat absorbed by the cold chain turnover box from the external environment per unit time; The refrigeration power of the refrigeration system of the cold chain turnover box is adjusted according to the heat absorption and the target temperature.
[0010] By adopting the above technical solution and measuring the comprehensive change in heat in the cold chain turnover box per unit time, we can accurately understand the source and destination of the heat of the temperature change in the box, determine the first cooling capacity of the refrigeration system per unit time at the current refrigeration power, and understand the refrigeration capacity of the refrigeration system at the current power. By calculating the amount of heat absorbed, we can analyze the heat balance of the cold chain turnover box under specific conditions, that is, the heat exchange between the heat generated in the box and the external environment. By adjusting the refrigeration power based on the amount of heat absorbed and the target temperature, we can ensure that the temperature in the cold chain turnover box is always maintained within the target range, thereby improving the accuracy of temperature control.
[0011] In a preferred example, the present application may be further configured as follows: determining the comprehensive change in heat in the cold chain turnover box per unit time according to the target temperature data includes: Acquire the historical target temperature at a time that is a unit time away from the current time from the target temperature data; Calculating a target temperature difference between the target temperature and the historical target temperature; Obtaining the volume and specific heat capacity of the medicine transported in the cold chain turnover box; The comprehensive change in heat in the cold chain turnover box per unit time is calculated based on the target temperature difference, the volume and the specific heat capacity.
[0012] By adopting the above technical solution, the historical target temperature at the moment with a unit time distance from the current moment is obtained, so that the temperature change history of the cold chain turnover box in a short period of time can be traced, and basic data can be provided for calculating the comprehensive change in heat. By calculating the difference between the target temperature and the historical target temperature, the temperature change of the cold chain turnover box in unit time can be quantified. According to the target temperature difference, volume and specific heat capacity, the comprehensive change in heat in the cold chain turnover box in unit time is calculated using the principles of thermodynamics, and the calculation process is scientific and accurate.
[0013] In a preferred example, the present application may be further configured as follows: if the target temperature reaches the upper limit temperature of the target temperature range; The step of adjusting the refrigeration power of the refrigeration system of the cold chain turnover box according to the heat absorption and the target temperature includes: Calculating the average of the upper limit temperature and the lower limit temperature of the transport temperature range, and determining the heat difference that needs to be discharged to reduce the target temperature to the average value; Acquire the maximum refrigeration power of the refrigeration system, and determine a second refrigeration capacity of the refrigeration system per unit time at the maximum refrigeration power according to the current refrigeration power and the first refrigeration capacity; Determine the cooling time required to reduce the target temperature to the average value according to the heat absorption, the second cooling capacity and the heat difference; Based on the cooling time and the amount of heat absorbed, the refrigeration power of the refrigeration system of the cold chain turnover box is adjusted.
[0014] By adopting the above technical solution, the heat difference required to reduce the target temperature to the average value of the transportation temperature range is calculated, and the excess heat that needs to be removed by the refrigeration system is clarified, which can ensure the accuracy and effectiveness of the adjustment measures and avoid over-refrigeration or under-refrigeration. The cooling time is calculated based on the heat absorption, the second cooling capacity and the heat difference, which provides a time plan for system adjustment and helps to achieve a smooth transition of temperature control. The refrigeration power is adjusted based on the cooling time and the heat absorption, so that the output of the refrigeration system can dynamically adapt to the temperature changes in the cold chain turnover box, thereby achieving more precise temperature control.
[0015] In a preferred example, the present application may be further configured as follows: adjusting the refrigeration power of the refrigeration system of the cold chain turnover box based on the cooling time and the amount of heat absorbed includes: determining a target cooling power according to the amount of heat absorbed; adjusting the current cooling power to the maximum cooling power; When the temperature drop time has passed since the current moment, the maximum cooling power is adjusted to the target cooling power.
[0016] By adopting the above technical solution, the target cooling power can be accurately calculated and determined, providing a clear goal for system adjustment. The cooling power can be adjusted to the maximum to quickly respond to temperature changes and ensure the quality of medicines. After the predetermined cooling time, the system can smoothly transition to the target cooling power to achieve smooth and energy-efficient operation.
[0017] In a preferred example, the present application may be further configured as follows: if the target temperature reaches the lower limit temperature of the target temperature range; The step of adjusting the refrigeration power of the refrigeration system of the cold chain turnover box according to the heat absorption and the target temperature includes: Calculating the average of the upper limit temperature and the lower limit temperature of the transport temperature range, and determining the target heat difference value that needs to be absorbed to increase from the target temperature to the average value; Determining the heating time required to increase the temperature from the target temperature to the average value according to the difference between the heat absorption and the target heat; shutting down the refrigeration system; A target cooling power is determined according to the heat absorption, and after the temperature rise time has elapsed from the current moment, the refrigeration system is turned on and the operating power of the refrigeration system is adjusted to the target cooling power.
[0018] By adopting the above technical solution, when the target temperature reaches the lower limit, the refrigeration system is turned off to prevent the temperature from being too low, and the subsequent heating process is planned according to the heating time and the target heat difference. When the heating time is over, the refrigeration system is turned on again and adjusted to the target refrigeration power to ensure that the temperature in the cold chain turnover box can smoothly return to the target range, thereby improving the accuracy and stability of temperature control.
[0019] In a second aspect, the present application provides a computer program product, which adopts the following technical solution: A computer program product includes a computer program.

If sensitive information is involved, the separate consent of the information subject needs to be obtained. The embodiments also need to be implemented with the authorization and consent of the object.
[0029] The present application provides a method for monitoring the temperature of a drug during transportation. Figure 1 As shown, the method provided in the embodiment of the present application is executed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, which is not limited in the embodiment of the present application. The method includes steps S101 to S104, wherein: S101. Obtain the category of medicines transported in the cold chain turnover box at the current moment, and multiple temperatures at different locations in the cold chain turnover box.
[0030] In this embodiment, multiple temperature sensors are arranged at different positions inside the cold chain turnover box. Optionally, temperature sensors can be arranged at the upper, middle and lower parts of the cold chain turnover box respectively. The cold chain turnover box is also provided with a positioning device and a refrigeration system. The positioning device sends the position information of the cold chain turnover box to the electronic device in real time. The refrigeration system receives the temperature control instruction sent by the electronic device and refrigerates the inside of the cold chain turnover box according to the temperature control instruction, so that the medicines inside the cold chain turnover box are in a specific low temperature environment.
[0031] Before the cold chain transfer box is transported, the transport personnel can set a unique number for the cold chain transfer box. During the transportation process, the location information sent by the positioning device and the temperature sent by the temperature sensor contain this number. The refrigeration system and the drug category are also bound to this number, so that the corresponding refrigeration system can be found by the number and the temperature can be adjusted according to the transportation temperature range of the drug category. Among them, the transportation temperature range corresponding to each drug category can be set by the transport personnel based on medical knowledge.
[0032] S102, determining the transportation temperature range corresponding to the drug category, and comparing multiple temperatures with the transportation temperature range respectively.
[0033] S103: If the multiple temperatures do not exceed the transportation temperature range, the average value of the multiple temperatures is calculated as the target temperature.
[0034] The transport temperature range is the temperature requirement for drug transportation. If any of the multiple temperatures exceeds the transport temperature range, it indicates that the temperature at a certain location in the cold chain transport box is too high or too low, that is, the temperature in the cold chain transport box is uneven. As a result, the electronic device can generate an alarm signal and send it to the terminal device of the transport personnel to prompt the transport personnel to check and determine the cause of the temperature imbalance. For example, the cause may be an abnormal refrigeration system, damage to the cold chain transfer box, or improper placement of drugs resulting in poor cold air circulation, which in turn affects the uniformity of temperature distribution in the cold chain transfer box.
[0035] S104. Obtain target temperature data containing the target temperature in the cold chain turnover box during this transportation process, and adjust the refrigeration power of the refrigeration system of the cold chain turnover box according to the target temperature data.
[0036] If multiple temperatures during transportation do not exceed the transportation temperature range, the average temperature of multiple temperatures at each time is calculated as the target temperature, and a series of target temperatures including timestamps, namely target temperature data, are obtained. The refrigeration power of the refrigeration system at the start time can be set by the transportation personnel based on actual experience. During transportation, the purpose of adjusting the refrigeration power of the refrigeration system is to make the target temperature as close to and stable as possible near the middle value of the transportation temperature range to reduce the impact of temperature fluctuations on drug quality.
[0037] Specifically, the target temperature range can be set based on the transport temperature range, and when the target temperature reaches the upper limit temperature of the target temperature range or the lower limit temperature is about to exceed the target temperature range, the refrigeration power of the refrigeration system is adjusted. The lower limit temperature of the target temperature range is higher than the lower limit temperature of the transport temperature range, and the upper limit temperature of the target temperature range is lower than the upper limit temperature of the transport temperature range. Optionally, the average temperature of the upper limit temperature and the lower limit temperature of the transport temperature range is calculated, and then the average value of the average temperature and the upper limit temperature of the transport temperature range is used as the upper limit temperature of the target temperature range, and the average value of the average temperature and the lower limit temperature of the transport temperature range is used as the lower limit temperature of the target temperature range.
[0038] The embodiment of the present application obtains the drug category and the temperature of different positions in the box in real time. Multi-point temperature monitoring can provide more comprehensive temperature data, which helps to more accurately evaluate the temperature distribution in the box and reduce the error that may be caused by a single monitoring point. The measured temperature is compared with the temperature range required for drug transportation to ensure that the drug is always within the specified temperature range during the entire transportation process, thereby ensuring the quality and safety of the drug. The use of average values can reduce misjudgments caused by single-point temperature fluctuations and improve the stability and reliability of temperature control. The refrigeration power of the refrigeration system is dynamically adjusted according to the target temperature data obtained in real time to ensure that the temperature in the cold chain turnover box is always maintained at the optimal state. Dynamic adjustment of the refrigeration power can not only ensure the quality of the drug, but also effectively reduce energy consumption, improve the energy efficiency of cold chain transportation, and realize the automatic management and control of the temperature of the cold chain turnover box, reduce manual intervention, and improve management efficiency and accuracy.
[0039] A possible implementation of the embodiment of the present application is to adjust the refrigeration power of the refrigeration system of the cold chain turnover box according to the target temperature data, including: The target temperature range is determined according to the transportation temperature range, the lower limit temperature of the target temperature range is higher than the lower limit temperature of the transportation temperature range, and the upper limit temperature of the target temperature range is lower than the upper limit temperature of the transportation temperature range; Compare the target temperature to the target temperature range; If the target temperature reaches the upper limit or lower limit of the target temperature range, the refrigeration power of the refrigeration system of the cold chain turnover box is adjusted according to the target temperature data.
[0040] The embodiment of the present application provides an additional safety buffer for drug transportation by setting a target temperature range that is narrower than the transportation temperature range, helping to ensure that the drugs are kept within the ideal temperature range even under slight temperature fluctuations. Once the target temperature is found to be approaching or reaching the boundary of the target temperature range, the system can respond immediately to prevent the temperature from exceeding the transportation temperature range. When the target temperature approaches the upper limit, the refrigeration power is increased to prevent overheating; when it approaches the lower limit, the refrigeration power is reduced to prevent overcooling.
[0041] A possible implementation of the embodiment of the present application is to adjust the refrigeration power of the refrigeration system of the cold chain turnover box according to the target temperature data, including: Determine the comprehensive change in heat in the cold chain turnover box per unit time based on the target temperature data; Acquire the current cooling power of the refrigeration system, and determine the first cooling capacity of the refrigeration system per unit time at the current cooling power; The heat absorption is determined based on the comprehensive change heat and the first cooling capacity. The heat absorption represents the heat absorbed by the cold chain turnover box from the external environment per unit time. Adjust the refrigeration power of the cold chain turnover box's refrigeration system according to the amount of heat absorbed and the target temperature.
[0042] In this embodiment, the unit time can be flexibly set by the transport personnel according to actual needs, and optionally, the unit time can be 30 minutes. The unit time represents the time period from the moment that is the unit time away from the current moment to the current moment, and the refrigeration power of the refrigeration system is constant during the time period. If the time from the start time of the transport process to the current moment is less than the unit time, the time from the start time of the transport process to the current moment is taken as the unit time.
[0043] The comprehensive change in heat Q0 represents the change in heat inside the cold chain turnover box per unit time when the cold chain turnover box absorbs heat from the external environment and receives the first cooling capacity of the refrigeration system at the same time. It can be estimated based on the specific heat capacity and volume of the medicines in the cold chain turnover box. When the target temperature in the cold chain turnover box increases per unit time, the obtained comprehensive change in heat Q0 is a positive number. When the target temperature in the cold chain turnover box decreases per unit time, the obtained comprehensive change in heat Q0 is a negative number.
[0044] The first cooling capacity Q1 represents the total amount of heat removed from the cold chain transfer box by the refrigeration system per unit time, which can be determined by the transport personnel according to the characteristics of the refrigeration system. If the refrigeration system is a water cooling system, the water flow rate per unit time and the water temperature difference between the inlet water temperature and the outlet water temperature of the refrigeration system are obtained, and the product of the water flow rate, the water temperature difference and the specific heat capacity of water is calculated as the first cooling capacity Q1 of the refrigeration system per unit time.
[0045] Furthermore, the sum of the comprehensive change heat amount Q0 and the first cooling amount Q1 is calculated as the heat absorption amount Q2.
[0046] The embodiments of the present application can accurately understand the source and destination of the heat of the temperature change in the box by measuring the comprehensive change in heat in the cold chain turnover box per unit time, determine the first cooling capacity of the refrigeration system per unit time at the current refrigeration power, and understand the refrigeration capacity of the refrigeration system at the current power. By calculating the amount of heat absorbed, the heat balance of the cold chain turnover box under specific conditions can be analyzed, that is, the heat exchange between the heat generated in the box and the external environment. The refrigeration power can be adjusted based on the amount of heat absorbed and the target temperature to ensure that the temperature in the cold chain turnover box is always maintained within the target range, thereby improving the accuracy of temperature control.
[0047] A possible implementation of the embodiment of the present application is to determine the comprehensive change in heat in the cold chain turnover box per unit time according to the target temperature data, including: Obtain the historical target temperature at a time that is a unit time away from the current time from the target temperature data; Calculate a target temperature difference between the target temperature and the historical target temperature; Obtain the volume and specific heat capacity of the medicines transported in the cold chain turnover box; Based on the target temperature difference, volume and specific heat capacity, calculate the comprehensive change in heat in the cold chain turnover box per unit time.
[0048] In this embodiment, the target temperature difference = target temperature - historical target temperature. A positive target temperature difference indicates that the target temperature in the cold chain turnover box increases within a unit time, and a negative target temperature difference indicates that the target temperature in the cold chain turnover box decreases within a unit time. Comprehensive change heat = target temperature difference × volume × specific heat capacity. The specific heat capacity can be set by the transporter according to the type of medicine.
[0049] The embodiment of the present application can trace the temperature change history of the cold chain turnover box in a short period of time by obtaining the historical target temperature at a moment with a unit time distance from the current moment, provide basic data for calculating the comprehensive change in heat, and calculate the difference between the target temperature and the historical target temperature to quantify the temperature change of the cold chain turnover box in unit time. According to the target temperature difference, volume and specific heat capacity, the comprehensive change in heat in the cold chain turnover box in unit time is calculated using the principles of thermodynamics, and the calculation process is scientific and accurate.
[0050] A possible implementation of the embodiment of the present application is that if the target temperature reaches the upper limit temperature of the target temperature range; According to the amount of heat absorbed and the target temperature, adjust the refrigeration power of the refrigeration system of the cold chain turnover box, including: Calculate the average of the upper and lower temperatures of the transport temperature range, and determine the heat difference that needs to be removed to reduce the target temperature to the average value; Acquire the maximum cooling power of the refrigeration system, and determine the second cooling capacity of the refrigeration system per unit time at the maximum cooling power according to the current cooling power and the first cooling capacity; Determine the cooling time required to reduce the target temperature to the average value according to the heat absorption, the second cooling capacity and the heat difference; Adjust the refrigeration power of the refrigeration system of the cold chain turnover box based on the cooling time and the amount of heat absorbed.
[0051] In one possible scenario, the target temperature reaches the upper limit of the target temperature range, and the refrigeration power of the refrigeration system needs to be increased. Average value = (upper limit of the target temperature range + lower limit of the target temperature range) / 2, first temperature difference = average value - target temperature, the first temperature difference is a negative number, indicating that cooling is required. Heat difference = first temperature difference × volume × specific heat capacity, the volume and specific heat capacity are the volume and specific heat capacity of the medicines transported in the cold chain turnover box. The sum of the heat removed from the cold chain transfer box per unit time by the refrigeration system at the current refrigeration power is the first refrigeration capacity Q1, the current refrigeration power is expressed as P1, and the second refrigeration capacity Q3 under the maximum refrigeration power Pm is determined according to the first refrigeration capacity Q1 and the current refrigeration power P1, Q3=Pm×Q1 / P1. In the process of cooling the target temperature of the cold chain transport box, the cold chain transport box will absorb heat from the external environment, and the heat absorbed per unit time is the heat absorption Q2. The cooling time Δt = heat difference / (Q2-Q3). Among them, the heat difference is a negative number, indicating the heat that needs to be dissipated, and Q2 is less than Q3, which means that the refrigeration effect of the refrigeration system can further dissipate the heat of the cold chain transport box while offsetting the absorbed heat Q2 to reduce the internal temperature to the average value.
[0052] The embodiment of the present application calculates the heat difference required to reduce the target temperature to the average value of the transportation temperature range, clarifies the excess heat that needs to be removed by the refrigeration system, ensures the accuracy and effectiveness of the adjustment measures, avoids over-refrigeration or under-refrigeration, and calculates the cooling time based on the heat absorption, the second cooling capacity and the heat difference, which provides a time plan for system adjustment and helps to achieve a smooth transition of temperature control. The refrigeration power is adjusted based on the cooling time and the heat absorption, so that the output of the refrigeration system can dynamically adapt to the temperature changes in the cold chain turnover box, thereby achieving more precise temperature control.
[0053] A possible implementation of the embodiment of the present application is to adjust the refrigeration power of the refrigeration system of the cold chain turnover box based on the cooling time and the amount of heat absorbed, including: Determine the target cooling power based on the amount of heat absorbed; Adjust the current cooling power to the maximum cooling power; When the temperature drop time has elapsed after the current moment, the maximum cooling power is adjusted to the target cooling power.
[0054] In this embodiment, the target refrigeration power = current refrigeration power × Q2 / Q1, and the refrigeration capacity of the refrigeration system under the target refrigeration power per unit time just offsets the amount of heat absorbed by the cold chain turnover box from the external environment per unit time.
[0055] When the target temperature reaches the upper limit of the target temperature range, the current refrigeration power is adjusted to the maximum refrigeration power. After the refrigeration system runs at the maximum refrigeration power for a cooling time of Δt, the refrigeration effect of the refrigeration system can further dissipate heat from the cold chain transport box while offsetting the heat absorption Q2, so that the internal temperature is reduced from the target temperature to the average value. After the cooling time Δt after the current moment, the internal temperature of the cold chain transport box is reduced to the average value, and the maximum refrigeration power is adjusted to the target refrigeration power.
[0056] The embodiment of the present application determines the target cooling power through precise calculation, provides a clear target for system adjustment, adjusts the cooling power to the maximum to quickly respond to temperature changes, ensures the quality of medicines, and smoothly transitions to the target cooling power after a predetermined cooling time, thereby achieving smooth and energy-efficient system operation.
[0057] A possible implementation of the embodiment of the present application is that if the target temperature reaches the lower limit temperature of the target temperature range; According to the amount of heat absorbed and the target temperature, adjust the refrigeration power of the refrigeration system of the cold chain turnover box, including: Calculate the average of the upper and lower temperatures of the transport temperature range, and determine the target heat difference required to increase the target temperature to the average value; According to the difference between the heat absorption and the target heat, determine the heating time required to increase the temperature from the target temperature to the average value; Turn off the refrigeration system; The target cooling power is determined according to the amount of heat absorbed, and after a temperature rise period has elapsed since the current moment, the refrigeration system is turned on and the operating power of the refrigeration system is adjusted to the target cooling power.
[0058] In another possible situation, the target temperature reaches the lower limit of the target temperature range, and the refrigeration power of the refrigeration system needs to be reduced. Average value = (upper limit temperature of the target temperature range + lower limit temperature of the target temperature range) / 2, the second temperature difference = average value - target temperature, the second temperature difference is a positive number, indicating that the temperature needs to be raised. Target heat difference = second temperature difference × volume × specific heat capacity, the volume and specific heat capacity are the volume and specific heat capacity of the medicines transported in the cold chain turnover box. In the process of cooling the target temperature of the cold chain transport box, the cold chain transport box will absorb heat from the external environment, and the heat absorbed per unit time is regarded as the heat absorption Q2. Heating time ΔT = target heat difference / Q2. Among them, the target heat difference is a positive number, indicating the heat that needs to be absorbed. When the target temperature reaches the lower limit temperature of the target temperature range, the refrigeration system is turned off, and the cold chain transport box absorbs heat from the external environment to make the target temperature reach the average value as soon as possible.
[0059] When the target temperature reaches the lower limit of the target temperature range, the current refrigeration system is turned off. Due to the heat absorbed by the cold chain turnover box from the external environment per unit time, the internal temperature of the cold chain transport box will rise. After a heating period of ΔT, the internal temperature of the cold chain transport box rises to the average value. The refrigeration system is turned on and the operating power is set to the target refrigeration power.
[0060] In the embodiment of the present application, when the target temperature reaches the lower limit, the refrigeration system is turned off to prevent the temperature from being too low, and the subsequent heating process is planned according to the heating time and the target heat difference. When the heating time is over, the refrigeration system is turned on again and adjusted to the target refrigeration power to ensure that the temperature in the cold chain turnover box can smoothly return to the target range, thereby improving the accuracy and stability of temperature control.
[0061] In summary, after a cooling period of Δt or a heating period of ΔT, the operating power of the refrigeration system is the target refrigeration power. The cooling capacity of the refrigeration system under the target refrigeration power per unit time just offsets the heat absorbed by the cold chain turnover box from the external environment per unit time, so that the internal temperature of the cold chain transport box is stabilized near the average value.
