Description

Technical Field

[0001] This application relates to the field of temperature and humidity detection and quality monitoring technology, and in particular to a method and apparatus for adjusting the thermal capacity coefficient of a temperature and humidity sensor. Background Technology

[0002] Most temperature and humidity loggers on the market currently consist of a logger plus an external temperature and humidity probe. The external sensor's packaging varies. The temperature and humidity probe's structure involves an internal electronic sensor soldered onto a printed circuit board, with an external plastic shell holding the circuit board in place. Therefore, when collecting ambient temperature and humidity data, instantaneous fluctuations occur due to ventilation, air convection, or temperature differences between indoors and outdoors during door opening and closing. Furthermore, the stored items, such as liquid preparations, reagents, biological samples, and blood, exhibit heat capacity due to their different materials and physical properties, preventing instantaneous changes in their internal temperature and humidity. Therefore, traditional temperature and humidity loggers cannot accurately reflect the actual internal temperature and humidity of different items.

[0003] Currently, most temperature and humidity loggers use sensors soldered onto circuit boards of equal volume, made of materials such as epoxy resin, phenolic resin, and polyimide. Therefore, their heat capacity differs significantly from that of pharmaceuticals, reagents, biological samples, and blood. The ambient temperature and humidity detected, or the temperature and humidity of a refrigerator, are actually the temperature and humidity of the logger itself within the storage environment or a specific area of ​​the refrigerator. Since storage environments can range from ultra-low temperatures below -40℃, to freezing temperatures from -40℃ to 0℃, or refrigeration temperatures from 0 to 10℃, cooling is achieved through air convection using fans. In addition, occasional opening and closing of the door, due to the temperature difference between indoors and outdoors, causes the sensors to detect instantaneous temperature and humidity changes. For pharmaceuticals, reagents, vaccines, and blood, which have high storage requirements, these instantaneous changes may lead to the storage temperature conditions being deemed unacceptable. Consequently, the batch of pharmaceuticals, reagents, vaccines, and blood may be scrapped under quality management requirements. This approach fails to meet the practical needs of the medical industry, which demands precision, high quality, and zero error. Summary of the Invention

[0004] In view of this, this application proposes a method for adjusting the thermal capacity coefficient of a temperature and humidity sensor, comprising the following steps: The adjustment screw is driven by a drive motor, and the adjustment screw moves the carrier plate away from or closer to the temperature and humidity sensor to obtain the heat capacity coefficient. By adjusting the lever to slide the baffle left and right, the number of multiple vent holes on the outer shell is changed, thus obtaining the amount of air intake from outside into the outer shell. Based on the thermal capacity coefficient and air intake volume, combined with a preset algorithm to simulate the thermal capacity of different items or materials, the temperature rise rate of the temperature and humidity sensor is adapted to the temperature rise rate of the target item, thereby simulating the internal temperature rise of the target item.

[0005] In one possible implementation, the heat capacity coefficient is obtained by driving an adjusting screw with a drive motor, which moves the carrier plate away from or towards the temperature and humidity sensor. This includes the following steps: Set the forward or reverse direction of the drive motor to determine the direction of movement of the support plate; The drive motor drives the adjusting screw to rotate, and the adjusting screw converts the rotational motion into linear motion, pushing the carrier plate along a preset trajectory to move closer to or away from the temperature and humidity sensor. Based on the actual moving distance of the bearing plate and the gradual thickness parameter of the bearing plate from thin to thick, the thermal capacity coefficient matching the current contact state is calculated.

[0006] In one possible implementation, the baffle is slid left and right by an adjusting rod to change the number of multiple vents on the outer casing, thereby obtaining the amount of external air entering the casing. This includes the following steps: Determine the number of vent openings and closings corresponding to the target air intake volume, and mark the target position where the baffle needs to slide. Applying external force to the protruding adjusting rod causes the baffle to move left and right along the sliding track inside the outer shell; When the baffle moves to the target position, the external force is stopped, and the number of vents that are currently open is counted to obtain the amount of air intake from outside into the shell.

[0007] In one possible implementation, based on the heat capacity coefficient and air intake volume, and combined with a preset algorithm simulating the heat capacity of different items or materials, the temperature rise rate of the temperature and humidity sensor is adapted to the temperature rise rate of the target item to obtain a simulation of the internal temperature rise of the target item, including the following steps: Input the heat capacity coefficient and air intake volume into a database of preset algorithms that simulate the heat capacity of different items or materials; The algorithm for simulating the heat capacity of different items or materials calls the basic temperature and humidity test data of the corresponding target items stored in the database and matches and calculates them with the input heat capacity coefficient and air intake volume; Based on the calculation results, the temperature rise rate parameter of the temperature and humidity sensor is adjusted to match the temperature rise rate of the target item, and finally the simulation of the internal temperature rise of the target item is collected and displayed.

[0008] In one possible implementation, the method of adjusting the baffle to slide left and right by adjusting the lever to change the number of multiple vents on the outer casing, thereby obtaining the intake volume of external air into the outer casing, further includes the following steps: During the sliding process of the baffle, the opening and closing status of the vents is monitored in real time, and the change in the number of vents opening and closing corresponding to each preset sliding distance of the baffle is recorded. Based on the curve of the change in the number of vent openings and closings, and combined with the internal space volume parameters of the outer shell, the calculation results of the air intake volume are corrected.

[0009] In one possible implementation, obtaining the heat capacity coefficient by driving an adjusting screw with a drive motor, and the adjusting screw moving the carrier plate away from or towards the temperature and humidity sensor, further includes the following steps: During the movement of the support plate, the real-time distance between the support plate and the temperature and humidity sensor is collected in real time through the position sensor; The real-time distance is compared with the preset safe distance threshold. If the real-time distance is less than the safe distance threshold, the drive motor is controlled to stop running.

[0010] In one possible implementation, based on the heat capacity coefficient and air intake volume, and combined with a preset algorithm simulating the heat capacity of different items or materials, the temperature rise rate of the temperature and humidity sensor is adapted to the temperature rise rate of the target item to obtain a simulation of the internal temperature rise of the target item. This also includes the following steps: Experiments are conducted on the confirmed simulated objects or materials to obtain experimental data; The target heat capacity coefficient is obtained based on experimental data. The motor is driven by remote command to adjust the position of the support plate and change the heat capacity coefficient of the temperature and humidity sensor, thereby simulating the internal temperature rise of the simulated object or material.

[0011] This application also provides a device for adjusting the thermal capacity coefficient of a temperature and humidity sensor, comprising: a housing, a temperature and humidity sensor, an adjustment component, a baffle, and an adjustment rod; The outer shell has a rectangular structure, with multiple ventilation holes on one side and a through hole on the front. The temperature and humidity sensor is mounted on a circuit board inside the housing; The adjustment component is located on one side of the temperature and humidity sensor, and is suitable for adjusting the heat capacity coefficient of the temperature and humidity sensor. The baffle is located inside the housing, which is adapted to multiple ventilation holes; One end of the adjusting rod is connected to the baffle, and the other end of the adjusting rod protrudes through the through hole and out of the front of the outer shell, with the protruding part having a preset length.

[0012] In one possible implementation, the adjustment assembly includes a drive motor, an adjustment screw, and a support plate; An internal mounting bracket is provided, located on the side of the temperature and humidity sensor, and the drive motor is mounted on the mounting bracket. One end of the adjusting screw is coaxially connected to the output shaft of the drive motor via a coupling; The support plate is connected to the other end of the adjusting screw, and the support plate is suitable for contacting the temperature and humidity sensor.

[0013] One possible implementation also includes a display screen, LED indicators, and a buzzer; A display area is provided on the top surface of the casing, and the display area extends through the interior of the casing. The size of the display screen matches the size of the display area. The LED indicator and buzzer are located inside the casing.

[0014] The beneficial effects of this invention are: By adjusting the contact area between the sensor soldered on the circuit board and the heat-capacity material, the size of the vent holes in the sensor housing, and combining this with a pre-stored heat-capacity algorithm, the temperature rise rate of the sensor can be precisely controlled to simulate the temperature rise rate of different items. Based on the adjustable temperature and humidity sensor heat capacity coefficient method described in this application, the problem of traditional temperature and humidity recorders being prone to misjudging items as unqualified due to the large difference between the sensor heat capacity and the target items such as liquid preparations, reagents, biological samples, and blood, and being easily affected by instantaneous temperature and humidity fluctuations, can be effectively solved. This method accurately reflects the actual internal temperature and humidity of the target item, meeting the stringent requirements of precise, high-quality, and zero-error temperature and humidity monitoring in fields such as drug clinical trials, pharmaceuticals, vaccines, and blood, and avoiding resource waste and cost losses caused by the misjudgment and scrapping of qualified items.

[0022] The method and apparatus for adjusting the heat capacity coefficient of the temperature and humidity sensor disclosed in this application is an optimized temperature and humidity monitoring technology that uses mechanical structure to adjust the contact area between the sensor and the heat capacity material, the size of the vent holes in the outer shell, and an algorithm to pre-store the heat capacity coefficient algorithm. This achieves precise control of the sensor's temperature rise rate and simulates the heat capacity state of different items. Applied to the field of temperature and humidity detection and quality monitoring technology, it solves the problem that traditional temperature and humidity recorders are prone to misjudging items as unqualified due to the large difference between the sensor's heat capacity and the target items such as liquid preparations, reagents, biological samples, and blood. This is because such recorders are easily affected by instantaneous temperature and humidity fluctuations in the environment (such as fan convection in refrigerated environments and temperature differences when opening and closing doors). The device accurately reflects the actual internal temperature and humidity of the target items, meeting the stringent requirements of precise, high-quality, and zero-error temperature and humidity monitoring in fields such as drug clinical trials, pharmaceuticals, vaccines, and blood. It also avoids resource waste and cost losses caused by the misjudgment and scrapping of qualified items.

[0023] Specific references Figures 1-2As a specific embodiment of the adjustable temperature and humidity sensor 120 heat capacity method and apparatus of this application, the adjustable temperature and humidity sensor 120 heat capacity method includes the following steps: 100. The adjusting screw 132 is driven by the drive motor 131, and the adjusting screw 132 moves the bearing plate 133 away from or closer to the temperature and humidity sensor 120 to obtain the heat capacity coefficient.

[0024] Specifically, the thermal properties of the target item are matched by changing the physical contact state. The drive motor 131 serves as the power source. Remote commands are sent from the server via manual sliding or remote control. Upon receiving the command, the drive motor 131's rotation direction (forward / reverse) determines the movement direction of the support plate 133. Forward rotation pushes the support plate 133 closer to the temperature and humidity sensor 120, while reverse rotation moves it away, ensuring flexible adjustment of the contact level as needed. The key function of the adjusting screw 132 is motion conversion, transforming the rotational motion output by the motor into linear motion of the support plate 133 along a preset trajectory, preventing the support plate 133 from shifting and causing adjustment failure. The support plate 133 employs a gradually increasing thickness design, and its contact area with the temperature and humidity sensor 120 changes with the moving distance: a larger contact area allows the temperature and humidity sensor 120 to absorb more heat from the thermally variable material, resulting in a higher thermal capacity coefficient. Conversely, a smaller contact area results in a lower thermal capacity coefficient. Finally, by combining the moving distance with the parameters of the gradually increasing thickness, the thermal capacity coefficient matching the current contact state can be accurately obtained.

[0025] 200. By adjusting the lever 150, the baffle 140 is slid left and right to change the number of multiple vent holes 001 on the outer shell 110, thereby obtaining the amount of external air entering the interior of the outer shell 110.

[0026] Specifically, the microenvironment of the sensor is stabilized by controlling the amount of external air exchange. The adjusting rod 150 serves as the operating mechanism; one end is fixedly connected to the baffle 140, and the other end protrudes from the outer shell 110 for easy manual application. Operators can directly move the baffle 140 left and right along the sliding track inside the outer shell 110 by pushing the adjusting rod 150, making operation convenient and precise. The core function of the baffle 140 is to block or expose the vents 001: when the baffle 140 slides to the right, it gradually blocks the vents 001 on one side of the outer shell 110, reducing the number of open vents 001 and thus reducing the rate at which external air enters the outer shell 110. When the baffle 140 slides to the left, it gradually exposes the vents 001, increasing the number of open vents and improving the air intake rate. Finally, by counting the number of open vents 001, the amount of external air entering the outer shell 110 can be determined. The smaller the air intake, the weaker the influence of external convection and temperature differences caused by opening and closing the door on the internal temperature and humidity of the outer shell 110. The larger the air intake, the better it can adapt to storage environments with strong ventilation, thus balancing anti-interference and environmental adaptability, and avoiding instantaneous data fluctuations caused by the uncontrollable air intake of traditional recorders.

[0027] 300. Based on the heat capacity coefficient and air intake volume, combined with the preset heat capacity algorithm for simulating different items or materials, the temperature rise rate of the temperature and humidity sensor 120 is adapted to the temperature rise rate of the target item, thereby simulating the internal temperature rise of the target item.

[0028] Specifically, firstly, the heat capacity coefficient and air intake volume obtained in the first two steps are input into the database of the heat capacity algorithm simulating different items or materials, providing the algorithm with real-time operating parameters. Next, the algorithm calls upon the pre-stored "target item temperature and humidity test baseline data" in the database. This data is obtained through prior temperature rise curve tests on different items such as liquid preparations, blood, and vaccines under standard environments, containing key information such as the item's own heat capacity characteristics and temperature rise rate. Subsequently, the algorithm matches the real-time parameters with the baseline data, analyzes the difference between the current sensor's temperature rise rate and the target item, and then automatically adjusts the sensor's temperature rise rate parameters to ensure that the sensor's temperature rise rate is completely consistent with the target item. Ultimately, the sensor no longer collects the temperature and humidity of its own environment, but rather temperature and humidity data synchronized with the internal changes of the target item. After processing, this data is output and displayed, completely solving the core problem that "traditional recorder data cannot reflect the actual internal state of an item," and meeting the precise temperature and humidity monitoring requirements of the medical field.

[0029] Furthermore, such as Figure 1As shown, the adjustable temperature and humidity sensor 120 heat capacity method of this application obtains the heat capacity coefficient through step 100, "drive motor 131 to drive adjustment screw 132 to move support plate 133 away from or near temperature and humidity sensor 120", and obtains the air intake volume of external air by step 200, "adjustment rod 150 drives baffle 140 to slide left and right to change the number of vent holes 001 of outer shell 110". Then, through step 300, "based on heat capacity coefficient and air intake volume combined to simulate heat capacity algorithm of different items or materials", the temperature rise rate of temperature and humidity sensor 120 is adapted to the target item, and finally the simulation of internal temperature rise of target item is obtained.

[0030] In one possible implementation, the adjustment screw 132 is driven by the drive motor 131, and the adjustment screw 132 moves the support plate 133 away from or towards the temperature and humidity sensor 120. The heat capacity coefficient is obtained by the following steps: Set the forward or reverse rotation direction of the drive motor 131 to determine the moving direction of the support plate 133.

[0031] The drive motor 131 drives the adjusting screw 132 to rotate, and the adjusting screw 132 converts the rotational motion into linear motion, pushing the carrier plate 133 to move closer to or away from the temperature and humidity sensor 120 along a preset trajectory.

[0032] Based on the actual moving distance of the bearing plate 133 and the gradual thickness parameter of the bearing plate 133 from thin to thick, the thermal capacity coefficient matching the current contact state is calculated.

[0033] Specifically, first, the object or material to be simulated is determined. Then, based on the thermal capacity coefficient or thermal conductivity rate obtained from the experimental data, the motor 131 is driven by a remote command to adjust the support plate 133, thereby changing the thermal capacity coefficient or thermal conductivity rate of the temperature and humidity sensor, thus simulating the internal temperature rise of the actual object or material.

[0034] Furthermore, the carrier plate and the temperature and humidity sensor are tightly attached. Due to the different contact points, the temperature rise of the temperature and humidity sensor is conducted to the carrier plate, so that the temperature of the contact points of the carrier plate and the temperature and humidity sensor are the same. Different temperature rise times are required, thereby calculating the heat capacity coefficient or heat conduction rate.

[0035] In one possible implementation, the baffle 140 is slid left and right by adjusting the rod 150 to change the number of multiple vent holes 001 on the outer casing 110, thereby obtaining the intake volume of external air into the outer casing 110, including the following steps: Determine the number of vents 001 that open and close corresponding to the target air intake volume, and mark the target position where the baffle 140 needs to slide.

[0036] An external force is applied to the protruding adjusting rod 150, causing the baffle 140 to move left and right along the sliding track inside the outer casing 110.

[0037] When the baffle 140 moves to the target position, the external force is stopped, the number of vents 001 that are currently open is counted, and the amount of air intake from outside into the housing 110 is obtained.

[0038] In one possible implementation, based on the thermal capacity coefficient and air intake volume, combined with a preset algorithm simulating the thermal capacity of different items or materials, the temperature rise rate of the temperature and humidity sensor 120 is adapted to the temperature rise rate of the target item, thereby simulating the internal temperature rise of the target item.

[0039] The thermal capacity algorithm adapts the temperature rise rate of the temperature and humidity sensor 120 to the temperature rise rate of the target item, resulting in a simulation of the internal temperature rise of the target item. This simulation includes the following steps: Input the heat capacity coefficient and air intake volume into a database of preset heat capacity algorithms that simulate different items or materials.

[0040] The algorithm for simulating the heat capacity of different items or materials calls the basic temperature and humidity test data of the corresponding target item stored in the database and matches and calculates it with the input heat capacity coefficient and air intake volume.

[0041] Based on the calculation results, the temperature rise rate parameter of the temperature and humidity sensor 120 is adjusted to match the temperature rise rate of the target item, and finally the simulation of the internal temperature rise of the target item is collected and displayed.

[0042] In one possible implementation, the method of adjusting the baffle 140 by moving the adjusting rod 150 to slide left and right, thereby changing the number of multiple vent holes 001 on the outer casing 110 and obtaining the intake volume of external air into the outer casing 110, further includes the following steps: During the sliding process of the baffle 140, the opening and closing status of the vent 001 is monitored in real time, and the change in the number of vent 001 opening and closing corresponding to each preset sliding distance of the baffle 140 is recorded.

[0043] Based on the curve of the change in the number of opening and closing of the vent 001, and combined with the internal space volume parameters of the outer shell 110, the calculation result of the air intake volume is corrected.

[0044] In one possible implementation, the process of obtaining the heat capacity coefficient by driving the adjusting screw 132 with the drive motor 131, and the adjusting screw 132 moving the support plate 133 away from or towards the temperature and humidity sensor 120, further includes the following steps: During the movement of the carrier plate 133, the real-time distance between the carrier plate 133 and the temperature and humidity sensor 120 is collected in real time by the position sensor.

[0045] The real-time distance is compared with the preset safe distance threshold. If the real-time distance is less than the safe distance threshold, the drive motor 131 is controlled to stop running.

[0046] In one possible implementation, based on the heat capacity coefficient and air intake volume, and combined with a preset algorithm simulating the heat capacity of different items or materials, the temperature rise rate of the temperature and humidity sensor 120 is adapted to the temperature rise rate of the target item to obtain a simulation of the internal temperature rise of the target item. This also includes the following steps: Experiments are conducted on the confirmed simulated objects or materials to obtain experimental data; The target heat capacity coefficient is obtained based on experimental data. The motor 131 is driven by a remote command to adjust the position of the support plate 133 and change the heat capacity coefficient of the temperature and humidity sensor 120, thereby simulating the internal temperature rise of the simulated object or material.

[0047] This application also provides an adjustable temperature and humidity sensor 120 thermal capacity device, including: a housing 110, a temperature and humidity sensor 120, an adjustment component 130, a baffle 140, and an adjustment rod 150.

[0048] Specifically, the adjustable temperature and humidity sensor 120 thermal capacity device is mainly composed of a housing 110, a temperature and humidity sensor 120, an adjustment component 130, a baffle 140, and an adjustment rod 150, which realizes precise control of the working state of the temperature and humidity sensor 120 and effective shielding against environmental interference.

[0049] Furthermore, such as Figure 2 As shown, the overall structure of the adjustable temperature and humidity sensor 120 thermal capacity device is composed of multiple components working together. Among them, the outer shell 110 is the carrier of the entire device, providing installation space and physical protection for the internal temperature and humidity sensor 120, adjustment component 130, etc. The temperature and humidity sensor 120 is the core sensing element used to collect temperature and humidity data. The adjustment component 130 is the key to realizing thermal capacity adjustment. The baffle 140 is used to control the opening and closing of the vent 001. The adjustment rod 150 is the medium for operating the baffle 140. These components together form the complete structure of the adjustable temperature and humidity sensor 120 thermal capacity device.

[0050] The outer casing 110 has a rectangular structure. Multiple ventilation holes 001 are provided on one side of the outer casing 110, and a through hole is provided on the front of the outer casing 110.

[0051] Specifically, the housing 110 adopts a rectangular structure design, possessing good stability and spatial regularity, adaptable to various installation scenarios, and convenient for both flat mounting and hanging installation. Multiple ventilation holes 001 are provided on one side of the housing 110. These ventilation holes 001 are key channels for the exchange of external air with the interior of the housing 110. By changing the number of ventilation holes 001, the airflow entering the housing 110 can be flexibly adjusted, thereby controlling the ventilation of the microenvironment surrounding the temperature and humidity sensor 120. For example, in environments with large temperature and humidity fluctuations and strong ventilation, the number of ventilation holes 001 can be appropriately increased to allow for faster air renewal around the sensor, reducing the impact of local temperature and humidity anomalies on measurements; while in relatively stable environments sensitive to temperature and humidity changes, the number of ventilation holes 001 can be reduced to minimize external interference. The through hole on the front of the outer casing 110 provides a space for the installation and operation of the adjustment rod 150. The through hole design allows the adjustment rod 150 to be connected to the internal baffle 140 at one end and to protrude through the front of the outer casing 110 at the other end, making it convenient for the user to operate the baffle 140 from the outside. The preset length of the protruding part fully considers ergonomics, making it convenient for the user to apply force to push the adjustment rod 150 to achieve convenient control of the opening and closing state of the vent 001.

[0052] Furthermore, such as Figure 2 As shown, the outer casing 110 is rectangular, a structure that facilitates installation and adaptability to different usage scenarios. Multiple vents 001 are provided on one side of the outer casing 110. These vents 001 serve as channels for gas exchange between the external air and the internal environment. The air intake can be adjusted by controlling the number of vents opening and closing. The through hole at the front of the outer casing 110 provides a path for the adjusting rod 150 to pass through, allowing the user to operate the adjusting rod 150 from outside the outer casing 110 to control the movement of the baffle 140.

[0053] The temperature and humidity sensor 120 is mounted on the circuit board 160 inside the housing 110.

[0054] Specifically, the temperature and humidity sensor 120 is mounted on a circuit board 160 inside the housing 110. The circuit board 160 provides a stable electrical connection and signal transmission path for the sensor. On one hand, the various circuit components integrated on the circuit board 160, such as filtering circuits and amplification circuits, can preprocess the raw temperature and humidity signals collected by the sensor, remove noise interference, enhance signal strength, and ensure the accuracy and stability of the signal, making the temperature and humidity data output by the sensor more reliable. On the other hand, the housing 110 provides good physical protection for the circuit board 160 and the sensor, preventing damage to the sensor from external dust, moisture, collisions, and other factors, thus extending the sensor's service life. Furthermore, concentrating the sensor on the circuit board 160 facilitates the modular design and production of the entire device, making later maintenance and repair easier. In the event of a sensor failure, the corresponding circuit board 160 module can be quickly located and replaced, improving the repair speed.

[0055] Furthermore, such as Figure 2 As shown, the temperature and humidity sensor 120 is mounted on the circuit board 160 inside the housing 110. On the one hand, the circuit board 160 can provide stable electrical connection and signal processing support for the sensor. On the other hand, the housing 110 can protect the sensor from dust and moisture, ensuring that it can work stably in various environments.

[0056] Preferably, the internal circuit board 160 is simultaneously injected with silicone or industrial waterproof paint to protect the power board circuitry, and the various components of the housing 110 are sealed with waterproof adhesive strips to achieve an IP67 (or other level) waterproof rating.

[0057] The adjustment component 130 is located on one side of the temperature and humidity sensor 120, and the adjustment component 130 is suitable for adjusting the heat capacity coefficient of the temperature and humidity sensor 120.

[0058] Specifically, the adjustment component 130 is positioned adjacent to the temperature and humidity sensor 120 on one side, enabling precise adjustment of the sensor's thermal capacity coefficient. This adjustment component 130 primarily drives the adjustment screw 132 to rotate via the drive motor 131, thereby causing the support plate 133 to move closer to or away from the temperature and humidity sensor 120. The support plate 133 employs a gradually thickening structure design. When the support plate 133 approaches the sensor, the contact area increases, allowing the sensor to absorb more heat from the thermal capacity material on the support plate 133, thus increasing the thermal capacity coefficient. Conversely, when the support plate 133 moves away from the sensor, the contact area decreases, and the thermal capacity coefficient decreases. This mechanical adjustment method allows for flexible adjustment of the sensor's thermal capacity coefficient based on the thermal characteristics of different target items. This ensures that the sensor's temperature change characteristics are closer to those of the target item when measuring temperature and humidity, effectively avoiding the problem of inaccurate measurement results due to significant differences in the sensor's thermal capacity compared to the target item, thereby significantly improving the accuracy of temperature and humidity measurements.

[0059] Furthermore, such as Figure 2 As shown, the adjustment assembly 130 is disposed on one side of the temperature and humidity sensor 120. The adjustment assembly 130 includes a drive motor 131, an adjustment screw 132, and a support plate 133. The drive motor 131 drives the adjustment screw 132 to rotate, thereby pushing the support plate 133 closer to or further away from the temperature and humidity sensor 120. Because the support plate 133 has a gradually increasing thickness, its contact area with the temperature and humidity sensor 120 changes as the support plate 133 moves, thereby adjusting the thermal coefficient of the temperature and humidity sensor 120 to match the thermal characteristics of different target items.

[0060] The baffle 140 is disposed inside the housing 110 which is adapted to the multiple vents 001.

[0061] Specifically, the baffle 140 is installed inside the housing 110 and is adapted to multiple vent holes 001 opened on one side of the housing 110, and its function is crucial. When the adjusting rod 150 moves the baffle 140 left and right along the sliding track inside the housing 110 under the action of external force, the baffle 140 can block or expose the vent holes 001. For example, when the baffle 140 slides to the right, it will gradually cover part of the vent holes 001, reducing the number of vent holes 001 that are open, thereby reducing the flow of external air into the housing 110. Conversely, when the baffle 140 slides to the left, it will expose more vent holes 001, increasing the air intake. By precisely controlling the position of the baffle 140, the number of opening and closing of the vent 001 can be accurately adjusted, thereby flexibly adjusting the rate at which external air enters the interior of the housing 110. This effectively reduces the instantaneous interference of factors such as environmental ventilation, air convection, and temperature difference when opening and closing doors on the temperature and humidity sensor 120, ensuring that the sensor can collect more stable temperature and humidity data that is closer to the actual microenvironment of the target item.

[0062] Furthermore, such as Figure 2 As shown, the baffle 140 is located inside the housing 110 and is adapted to these vent holes 001. When the adjusting rod 150 moves the baffle 140 left and right, the baffle 140 can expose or block part of the vent holes 001, thereby changing the number of vent holes 001 that are open or closed, and thus controlling the amount of external air entering the housing 110, reducing the instantaneous interference of environmental factors on the temperature and humidity sensor 120.

[0063] Specifically, the baffle 140 is located inside the housing 110. By pushing a protruding adjusting rod 150, the opening and closing size of the vent 001 can be adjusted. With one baffle 140 and multiple vents 001, the number of vents 001 opening and closing can be adjusted by adjusting the left and right sliding of the baffle 140, thereby adjusting the amount of air intake.

[0064] One end of the adjusting rod 150 is connected to the baffle 140, and the other end of the adjusting rod 150 protrudes through the through hole and out of the front of the outer shell 110, and the protruding part has a preset length.

[0065] Specifically, the adjusting rod 150, as a key component of the operating baffle 140, is firmly connected to the baffle 140 at one end, ensuring stable movement of the baffle 140 during adjustment. The other end protrudes through a through hole on the front of the housing 110, and the pre-set length of the protrusion has been carefully considered. From an operational convenience perspective, the sufficient length allows the user to easily grasp the adjusting rod 150 and apply force to slide it left or right to change the position of the baffle 140. Simultaneously, the protruding design makes the adjusting rod 150 clearly visible outside the housing 110, facilitating user identification and operation. Even in low light or concealed installation locations, the user can quickly locate and operate the adjusting rod 150 by touch. This design extends the adjustment function of the internal baffle 140 to the outside of the housing 110, greatly improving user convenience and allowing the user to adjust the air intake of the vent 001 promptly and accurately according to actual environmental needs, optimizing the working environment of the temperature and humidity sensor 120.

[0066] Furthermore, such as Figure 2 As shown, one end of the adjusting rod 150 is connected to the internal baffle 140, and the other end protrudes through the through hole at the front of the outer casing 110 to the outside of the outer casing 110, with the protruding part having a preset length. This design allows the user to easily push the adjusting rod 150 from the outside of the outer casing 110, thereby causing the baffle 140 to slide and adjusting the number of opening and closing vent holes 001. The operation is simple and intuitive.

[0067] In one possible implementation, the adjustment assembly 130 includes a drive motor 131, an adjustment screw 132, and a support plate 133. A mounting bracket is provided inside the housing 110, located on one side of the temperature and humidity sensor 120. The drive motor 131 is mounted on the mounting bracket. One end of the adjustment screw 132 is coaxially connected to the output shaft of the drive motor 131 via a coupling. The support plate 133 is connected to the other end of the adjustment screw 132 and is adapted to contact the temperature and humidity sensor 120.

[0068] Specifically, by adjusting the contact area between the sensor soldered on the circuit board 160 and the heat-capacity material, as well as the size of the vent 001 in the sensor housing 110, and using an algorithm for the heat capacity coefficient, the temperature rise rate of the sensor can be adjusted to simulate the temperature rise rate of different items. A drive motor 131 is connected to an adjusting screw 132, which in turn is connected to a support plate 133. The drive motor 131 drives the adjusting screw 132 to rotate forward and backward, causing the support plate 133 to move closer to or further away from the temperature and humidity sensor 120, thereby changing the contact area between the heat-capacity material block and the temperature and humidity sensor 120. The support plate 133 can be structured from thin to thick, thus changing the heat capacity coefficient accordingly.

[0069] In one possible implementation, a display screen, LED indicator lights, and a buzzer are also included. A display area 002 is provided on the top surface of the housing 110, and the display area 002 extends through the interior of the housing 110. The size of the display screen matches the size of the display area 002, and the LED indicator lights and buzzer are located inside the housing.

[0070] Preferably, the casing 110 should be designed to accommodate the replacement of the battery 170 and the screen display. The screen display can adopt a modular and replaceable structure to achieve multiple display methods (LCD screen display, e-reader screen display, LED indicator display). Different display methods can cope with different temperature ranges, which can achieve the purpose of long-term use or long battery life.

[0071] Furthermore, the bottom of the outer casing 110 has a built-in strong magnet, which allows the device to be installed magnetically onto a metal surface. At the same time, an adjustable U-shaped bracket 180 is provided on both sides of the outer casing 110, which can also be placed vertically or suspended.

[0072] Furthermore, an external sensor is provided on the outer wall of the housing 110. The external sensor is used to calibrate the built-in temperature and humidity sensor 120 or to collect the temperature and humidity of the external environment.

[0073] Specifically, the external sensor is calibrated by a legal metrology institute and then connected to a temperature and humidity meter. The calibration is performed by comparing data from multiple temperature and humidity monitoring points.

[0074] Specifically, the feature of this application is that it adjusts the heat capacity of the sensor through a mechanical structure and develops a set of simulated heat capacity algorithms based on a large amount of internal temperature and humidity test data of different items. The two are combined to simulate the internal temperature and humidity changes of different items in the storage environment, so as to accurately determine whether the items meet the quality standards for temperature and humidity requirements. This application has great practical value, especially in drug clinical trials, pharmaceuticals, vaccines, blood and other industries where there are strict requirements for temperature and humidity.

[0075] The method and apparatus for adjusting the heat capacity coefficient of the temperature and humidity sensor disclosed in this application can drive an adjusting screw via a drive motor to move a support plate closer to or further away from the temperature and humidity sensor, and calculate the heat capacity coefficient in conjunction with the gradually changing thickness of the support plate. A position sensor monitors the distance in real time to ensure safety. An adjusting rod moves a baffle to change the number of opening and closing vents, and the opening and closing status of the vents is monitored in real time. The air intake is corrected based on the volume of the outer shell. Then, based on the heat capacity coefficient and air intake, the method calls upon the temperature and humidity test data of the target item from a database of heat capacity algorithms simulating different items or materials. After matching and calculation, the sensor's temperature rise rate is adjusted to adapt to the target item. It stores temperature and humidity data logs in real time and compares them with qualified standards to generate anomaly warnings. It can accurately simulate the internal temperature and humidity changes of target items such as liquid preparations, reagents, biological samples, and blood. It completely solves the problems of temperature and humidity sensors being too sensitive or too sluggish in environments with changing temperatures, and the problems of traditional temperature and humidity recorders misjudging qualified items as unqualified due to the large difference between the sensor's heat capacity and the target item, and the susceptibility to interference from instantaneous environmental fluctuations. It meets the stringent requirements of the medical field for precise, high-quality, and zero-error temperature and humidity monitoring, and avoids the waste of resources and cost losses caused by the scrapping of qualified items due to misjudgment.
