Description

Technical Field

[0001] The present invention relates to the field of temperature control systems, and more particularly to a temperature control system for storing sterile instrument packs. Background Art

[0002] Sterile instrument packs, such as surgical instruments, implants, etc., usually need to be stored and transported under strict temperature conditions. Cold chain transportation controls environmental factors such as temperature and humidity during transportation to prevent the reproduction and contamination of microorganisms, thereby ensuring the quality and safety of sterile instrument packs. This is of great significance for ensuring the success rate of surgeries and reducing the risk of infection. Generally, the storage temperature of sterile instrument packs should be maintained within the range below 24°C.

[0003] Chinese Patent Publication No.: CN109085868A discloses an automatic storage temperature control system for cold chain transportation. The system includes a temperature measurement tag, a data terminal, and a host computer provided with a database. Data interaction is realized between the data terminal and the temperature measurement tag and the host computer through NFC wireless communication technology. The temperature measurement tag is used to monitor the preservation temperature value of cold chain transportation items in real time and transmit the temperature value to the data terminal. The data terminal is used to receive the temperature value and process the temperature value. The host computer processes and evaluates all temperature values and provides data support for the evaluation; the temperature measurement tag includes a temperature measurement module, a first control processing module, and a first communication module; the data terminal includes a second communication module and a second control processing module, and data interaction is carried out between the second communication module and the first communication module. It can be seen that the above technical solution has high energy consumption due to the lack of an intelligent adjustment strategy, thus increasing the transportation cost. Summary of the Invention

[0004] Therefore, the present invention provides a temperature control system for storing sterile instrument packs to overcome the problem of high energy consumption in the cold chain transportation of sterile instrument packs in the prior art.

[0005] To achieve the above object, the present invention provides a temperature control system for storing sterile instrument packs, including:

[0006] A storage part, which is in a box structure and is arranged on the frame of an automobile, including an outer structure layer, an intermediate heat insulation layer, and an inner structure layer;

[0007] A temperature control part, including a first temperature control unit arranged on the top surface and the rear wall of the storage part and a second temperature control unit arranged on the front wall of the storage part. Among them,

[0008] The first temperature control unit includes a number of heat dissipation channels that penetrate through the top surface and the middle insulation layer between the rear wall of the storage part and the inner structure layer in parallel at equal intervals, a deflector plate provided at the inlet of each heat dissipation channel, an electric actuator connected to the deflector plate to control the opening and closing of the deflector plate, and an outlet of each heat dissipation channel provided at the bottom end of the rear wall of the storage part. The bottom end of the deflector plate is hinged to the outer structure layer of the storage part;

[0009] The second temperature control unit is a refrigeration unit, including a compression external machine provided on the outer side of the front wall of the storage part and an air outlet internal machine provided inside the storage part;

[0010] The power supply unit is connected to the temperature control unit, including the first power supply unit powered by the vehicle fuel system and the second power supply unit powered by an external battery;

[0011] The information collection module includes a path collection unit for collecting path information and a temperature collection unit for collecting the external temperature and the internal temperature of the storage part;

[0012] The control module is respectively connected to the temperature control unit, the power supply unit and the information collection module, and is used to determine the power supply strategy of the temperature control unit according to the power supply evaluation value, to determine the corresponding temperature control strategy for the next time period according to the average external temperature within the historical duration, and to determine whether the operation of the system meets the preset standard according to the temperature change inside the storage part within the preset time period.

[0013] Furthermore, spray heads are provided on the inner walls of each heat dissipation channel near the inlet, and each spray head is connected to a water tank respectively.

[0014] Furthermore, the control module determines the power supply strategy of the temperature control unit according to the power supply evaluation value, where

[0015] if the power supply evaluation value is less than the preset power supply evaluation value, only the first power supply unit is turned on to supply power to the temperature control unit;

[0016] if the power supply evaluation value is greater than or equal to the preset power supply evaluation value, the first power supply unit and the second power supply unit are jointly turned on to supply power to the temperature control unit.

[0017] Furthermore, the power supply evaluation value is jointly determined according to the length of the total path of a single transportation of the sterile instrument package obtained by the path collection unit and the number of traffic signal intersections on the path.

[0018] Furthermore, when the stagnation duration within the preset driving time period is greater than the preset stagnation duration, the control module corrects the preset power supply evaluation value.

[0019] Further, the correction amplitude of the preset power supply evaluation value is positively correlated with the difference in stagnation duration, where the difference in stagnation duration is the difference between the stagnation duration and the preset stagnation duration.

[0020] Further, the control module determines the temperature control strategy corresponding to the next time period according to the average external temperature within the historical duration, where

[0021] if the average external temperature is less than the first preset temperature threshold, the control module determines that the temperature control strategy corresponding to the next time period is not to turn on the first temperature control unit and the second temperature control unit;

[0022] if the average external temperature is greater than or equal to the first preset temperature threshold and less than the second preset temperature threshold, the control module determines that the temperature control strategy corresponding to the next time period is to only turn on the first temperature control unit;

[0023] if the average external temperature is greater than or equal to the second preset temperature threshold and less than the third preset temperature threshold, the control module determines that the temperature control strategy corresponding to the next time period is to turn on the first temperature control unit and the second temperature control unit;

[0024] if the average external temperature is greater than or equal to the third preset temperature threshold, the control module determines that the temperature control strategy corresponding to the next time period is to only turn on the second temperature control unit.

[0025] Further, the control module determines whether the operation of the system meets the preset standard according to the temperature change inside the storage unit within the preset time period under the first preset condition, where

[0026] if the temperature decreases, the control module determines that the operation of the system meets the preset standard and continues to operate the system according to the current temperature control strategy;

[0027] if the temperature rises and is less than the preset warning temperature, the control module determines that the operation of the system does not meet the preset standard and determines the adjustment method of the temperature control strategy according to the average vehicle speed within the preset time period;

[0028] if the temperature rises and is greater than or equal to the preset warning temperature, the control module determines that the operation of the system does not meet the preset standard and switches the temperature control strategy to turn on the first temperature control unit and the second temperature control unit together;

[0029] The first preset condition is to only turn on the first temperature control unit.

[0030] Further, the control module determines the adjustment method of the temperature control strategy according to the average vehicle speed within the preset time period, where

[0031] If the average vehicle speed is less than the preset average vehicle speed, the temperature control strategy is switched to only turn on the second temperature control unit;

[0032] If the average vehicle speed is greater than or equal to the preset average vehicle speed, the spraying amount of each spray head is increased according to the difference between the average vehicle speed and the preset average vehicle speed.

[0033] Furthermore, the control module is provided with several spray amount adjustment methods for the increase of the spray amount, and each spray amount adjustment method has a different increase amplitude for the spray amount.

[0034] Compared with the prior art, the beneficial effects of the present invention are as follows: The temperature control part of the present invention includes two temperature control units, and the temperature control strategy can be adjusted according to the actual transportation situation, improving the flexibility and adaptability of the temperature control system and ensuring the quality stability of the transported items during the whole transportation process.

[0035] Furthermore, the power supply part of the present invention includes two power supply units, and the power supply strategy can be adjusted according to the actual transportation situation, minimizing energy consumption to reduce transportation costs.

[0036] Furthermore, the first temperature control unit of the present invention uses the water atomization cooling method to greatly reduce energy consumption and carbon emissions, meeting the environmental protection concept of green and low carbon.

[0037] Furthermore, the present invention jointly determines the power supply evaluation value according to the length of the total path obtained by the path acquisition unit and the number of intersections on the path, and then flexibly adjusts the power supply strategy according to the power supply evaluation value, improving the energy utilization efficiency.

[0038] Furthermore, based on the fact that the stagnation duration during the driving process is greater than the preset stagnation duration, the present invention makes a correction to reduce the preset power supply evaluation value, which can further reduce energy consumption.

[0039] Furthermore, the control module of the present invention determines the corresponding temperature control strategy for the next time period according to the average outdoor temperature within the historical duration, improving the stability of the system.

[0040] Furthermore, the control module of the present invention determines whether the system operation meets the preset standard according to the temperature change inside the storage part under the first preset condition, and adjusts the temperature control strategy according to the average vehicle speed, improving the reliability of the system.

[0076] Specifically, turning on the first temperature control unit means turning on the deflector and the spray head.

[0077] Specifically, turning on the second temperature control unit means turning on the compressor external unit and the air outlet internal unit.

[0078] Specifically, under the first preset condition, the control module determines whether the operation of the system meets the preset standard according to the temperature change inside the storage unit within the preset time period, where
