Description

Technical Field

[0001] This invention relates to the field of bio-cold chain technology, specifically to an ultra-low temperature bio-intelligent warehousing and logistics system. Background Technology

[0002] In the fields of life sciences, medical pharmaceuticals, etc., the storage and transportation of cryogenic biological samples is crucial. These samples are extremely sensitive to temperature and humidity, and even slight environmental fluctuations can affect sample activity, leading to biased research results or damage to the quality of medical products. At the same time, with the rapid development of biotechnology, the number and types of samples are constantly increasing. Cryogenic biological intelligent warehousing and logistics creates a safe, efficient, and intelligent warehousing and transportation environment for cryogenic biological samples, promoting the steady progress of the biotechnology industry. Traditional transfer technologies mostly rely on manual opening of transfer containers.

[0003] However, with current technology, it takes a long time for manual opening of the transfer container to complete the transfer each time, which not only increases the sample exposure time but also affects the overall work efficiency. At the same time, when the opening and closing work is carried out, a large amount of hot air from the outside rushes in and undergoes strong heat exchange with the ultra-low temperature environment. Moisture condenses into frost on the surface of the container and the transfer channel, which has an adverse effect on the sample quality. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an ultra-low temperature biological intelligent warehousing and logistics system, which solves the problems of long time from opening the lid to completing the transfer, affecting overall work efficiency, and non-sealed transmission channels causing excessive influx of external hot air, resulting in frost condensation on the surfaces of containers and transmission channels.

[0013] Preferably, the inner wall of the transfer container is slidably connected to a support frame, the inside of which is provided with a sample placement slot for placing a sample storage box. The inner wall of the support frame is rotatably connected to a connecting rod, the outer wall of the connecting rod is rotatably connected to a support plate, the outer wall of the support plate is fixedly connected to a guide plate, the outer wall of the guide plate is slidably connected to the outer wall of the transfer container, the outer wall of the guide plate is fixedly connected to a magnetic component, the upper surface of the guide plate is fixedly connected to a composite plate, and the lower surface of the composite plate is slidably connected to the upper surface of the transfer container.

[0014] Preferably, a return spring is fixedly connected to the outer wall of the support plate, and the outer wall of the return spring is fixedly connected to the inner wall of the transfer container.

The clamping plate is used to position the sample storage box on the inner wall of the sample placement slot.

[0016] Preferably, the transfer container has a push rod slidably connected inside, one end of the push rod is fixedly connected to a support frame, and the other end of the push rod is fixedly connected to a fixing block. The outer wall of the fixing block is set on the inner wall of the fully enclosed transmission channel.

[0017] Preferably, the intelligent temperature and humidity coordinated control module includes an independent temperature control unit, an intelligent humidity regulation unit, and a prediction and adaptive regulation unit;

[0018] The independent temperature control unit is used to control and collect data independently of each cooling plate and digital temperature sensor.

[0019] The intelligent humidity control unit is used to continuously monitor the humidity inside the storage module through a dew point sensor, and to reduce the humidity inside the chamber through a molecular sieve when the humidity is greater than 30%.

[0020] The prediction and adaptive control unit is used to collect humidity and temperature data as a dataset, and train a long short-term memory network model based on the dataset to predict the trend of temperature and humidity changes, and dynamically adjust the cooling power of the cooling plate and the working time of molecular sieve adsorption.

[0021] Preferably, the intelligent temperature and humidity coordinated control module further includes a fault diagnosis unit, which is used to determine the operating faults of the cooling plate and molecular sieve by the temperature and humidity change trend and the operating status of the cooling plate and molecular sieve, and to report the faults.

[0022] Working principle: When storing or retrieving biological samples, the motor inside the transfer container is first turned on. The motor drives the gears to rotate, which in turn moves the entire transfer container along the inner wall of the fully enclosed transmission channel via a rack and pinion. At the same time, the low-temperature nitrogen circulation pipe conducts heat from the cold source to the interior of the transfer container through a heat-conducting plate. When the transfer container moves to the position of the sealing plate, the fixing block contacts the inner wall of the fully enclosed transmission channel, squeezing the push rod. The push rod can push the support frame to slide. At this time, the positioning plate slides outward through the movable plate, pulling open the sealing plate and opening the sampling slot. The sample storage box can be placed on the inner wall of the sample placement slot. Then, the sampling slot is closed, the return spring rebounds, and the support plates at both ends move in the middle, thereby pushing the support frame to slide through the connecting rod. The movable plate then positions the sample storage box by driving the clamp on the upper surface of the positioning plate, ensuring the stability of subsequent transportation.

[0023] Then, as the transfer container is transported to one side of the fully enclosed transmission channel inside the storage device, the electromagnetic coil generates a repulsive force on the magnetic components, which can drive the guide plates at both ends of the transfer container to slide outward, thereby causing the connecting plate to slide outward on the upper surface of the transfer container to open the inner wall of the transfer container. Then, the sample storage box is placed on the inner wall of the sample placement slot through the through groove in the inner wall of the storage device for transfer, realizing the rapid opening and closing of the transfer container, shortening the operation time, and reducing the risk of heat exchange and frost formation.

[0024] This invention provides an ultra-low temperature biological intelligent warehousing and logistics system. It has the following beneficial effects:

[0025] 1. This invention uses an electromagnetic coil to generate a repulsive force, which drives the guide plates at both ends of the transfer container to slide outward, thereby causing the composite plate to slide outward synchronously on the upper surface, thus opening the inner wall of the transfer container. Combined with a fully enclosed transmission channel, the transfer is completed, thereby achieving the effects of quickly opening and closing the transfer container, shortening the operation time, reducing heat exchange, and reducing the risk of frost formation.

[0026] 2. In this invention, after the transfer container leaves the storage device, the return spring rebounds, causing the guide plates at both ends to close, and then the transfer container is closed by the closing plate. At the same time, the connecting rod pushes the support frame to slide in the opposite direction on the inner wall of the transfer container. When the positioning plate moves, the movable plate drives the clamping plate to slide on the inner wall of the sample placement slot, positioning the sample storage box in the slot. This effectively avoids excessive shaking of the sample during transfer and ensures the stability and quality of the transfer.

[0027] 3. This invention collects temperature and humidity data and trains a long short-term memory network model. The trained model receives data in real time, predicts temperature and humidity trends, and dynamically adjusts the power of the cooling plate and the working time of the molecular sieve adsorption system based on the prediction, thereby improving the timeliness, energy efficiency, and stability of regulation.

[0036] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] Please see the appendix Figure 1 This invention provides an ultra-low temperature biological intelligent warehousing and logistics system, which includes a storage module, a rail transportation system, a transfer module, and an intelligent temperature and humidity coordinated control module.

[0038] The storage module is used to store samples;

[0039] The rail transport module is used to transfer the transfer module, and a refrigeration module is installed to continuously provide a cooling source for the transfer module during transportation.

[0040] The transit module is used to store the retrieved samples, awaiting further transportation of the samples;

[0041] The intelligent temperature and humidity control module is used to independently control the temperature and humidity of the six sides of the storage compartment of the storage module through a cooling plate, a temperature sensor, and a dew point sensor.

[0042] Specifically, the storage module uses multi-layer thermal insulation materials and vacuum technology to construct the chamber, reducing heat conduction, and is equipped with automated shelves inside, making it easy for staff to access samples and ensuring proper preservation of samples in an ultra-low temperature environment;

[0043] The rail transport system is used to regulate the cooling capacity of the transfer module to ensure that the temperature fluctuation of the transfer module does not exceed ±1℃ during transportation, thereby reducing the damage to the sample caused by temperature changes. At the same time, the fully enclosed transmission channel 3 can prevent the sample from being exposed to the open environment.

[0044] The transfer module uses a rail transport system to deliver the transfer container 6 to the designated location, completing the loading and unloading of samples. This avoids prolonged exposure of samples during the transfer process and improves the flexibility of the warehousing and logistics system in responding to different transportation needs.

[0045] The intelligent temperature and humidity coordinated control module installs cooling plates and digital temperature sensors on the six sides of the storage compartment. It collects temperature data from different locations in the compartment in real time, monitors humidity through a built-in dew point sensor, and controls the temperature of each side individually based on humidity and temperature, achieving the dual goals of high efficiency and energy saving and precise temperature control.

[0046] Reference Figure 2 and Figure 5 The storage module includes a warehouse 1, and a storage device 2 is installed inside the warehouse 1. A sample rack 28 is fixedly connected to the inner wall of the storage device 2. A sample storage box is installed on the upper surface of the sample rack 28. Biological samples are placed in the sample storage box for preservation. An electromagnetic coil 18 is installed on the inner wall of the storage device 2. A track transport system is installed on the inner wall of the storage device 2.

[0047] Specifically, warehouse 1 provides physical space for storage device 2, ensuring the space for storage device 2 to be placed. Storage device 2 also provides fixed support for sample rack 28, ensuring proper preservation and placement of samples in sample storage box. Storage device 2 also provides fixed support for electromagnetic coil 18, and controls the opening and closing of subsequent assembly plate 16 through the magnetic field generated by electromagnetic coil 18.

[0048] Reference Figures 2-5 The rail transport module includes a fully enclosed transmission channel 3. The outer wall of the fully enclosed transmission channel 3 is set inside the storage device 2. The outer wall of the fully enclosed transmission channel 3 is set inside the warehouse 1. The inner wall of the fully enclosed transmission channel 3 is provided with a guide rail 4. A rack 5 is fixedly connected to the inner wall of the guide rail 4. The inner wall of the fully enclosed transmission channel 3 is provided with a low-temperature nitrogen circulation pipe 9. A through groove 25 is opened inside one side of the fully enclosed transmission channel 3. A sampling groove 26 is opened inside the other side of the fully enclosed transmission channel 3. A sealing plate 27 is set on the upper surface of the fully enclosed transmission channel 3. The lower surface of the sealing plate 27 is set inside the sampling groove 26. The transfer module is located on the inner wall of the fully enclosed transmission channel 3.

[0049] Specifically, the fully enclosed transmission channel 3 is located on the inner wall of the storage device 2, enabling the retrieval of samples within a sealed, temperature-controlled buffer operating space, preventing samples from being exposed to an open environment. Simultaneously, the fully enclosed transmission channel 3 allows samples to be transferred outside the warehouse 1. The fully enclosed transmission channel 3 provides fixed support for the guide rail 4, which in turn supports the position of the rack 5, facilitating subsequent transfer by the transfer module. The fully enclosed transmission channel 3 also supports the position of the low-temperature nitrogen circulation pipe 9, which stabilizes the transfer temperature within the fully enclosed transmission channel 3. A through-slot 25 at one end of the fully enclosed transmission channel 3 facilitates the retrieval and storage of samples within the storage device 2. A sampling slot 26 on the other side of the fully enclosed transmission channel 3 allows the transfer module containing samples placed within the fully enclosed transmission channel 3 to transfer samples to the storage device 2, and also facilitates sample retrieval. A sealing plate 27 allows the sampling slot 26 to be opened and closed, ensuring the airtightness of the fully enclosed transmission channel 3 during transfer.

[0050] Reference Figure 6 and Figure 7 The transfer module includes a transfer container 6, with a gear 7 installed on the inner wall of the transfer container 6. The gear 7 is driven by an internal motor of the transfer container 6. The outer wall of the gear 7 is meshed with the upper surface of the rack 5. A heat-conducting plate 8 is fixedly connected to the lower surface of the transfer container 6. The lower surface of the heat-conducting plate 8 is connected to the upper surface of the low-temperature nitrogen circulation pipe 9.

[0051] Specifically, the transfer container 6 provides fixed support for the gear 7, and the transfer container 6 is equipped with a motor. The motor drives the gear 7 to rotate, thereby generating a reverse force through the meshing connection with the rack 5, which drives the entire transfer container 6 to move along the inner wall of the fully enclosed transmission channel 3. At the same time, the transfer container 6 provides fixed support for the heat-conducting plate 8. Through the transfer of cold source between the heat-conducting plate 8 and the low-temperature nitrogen circulation pipe 9, the constant low temperature inside the transfer container 6 can be fully contained, reducing temperature fluctuations during transmission.

[0052] Reference Figure 6 The inner wall of the transfer container 6 is slidably connected to a support frame 10. The inside of the support frame 10 is provided with a sample placement slot 11 for placing a sample storage box. The inner wall of the support frame 10 is rotatably connected to a connecting rod 12. The outer wall of the connecting rod 12 is rotatably connected to a support plate 13. The outer wall of the support plate 13 is fixedly connected to a guide plate 14. The outer wall of the guide plate 14 is slidably connected to the outer wall of the transfer container 6. The outer wall of the guide plate 14 is fixedly connected to a magnetic component 15. The upper surface of the guide plate 14 is fixedly connected to a composite plate 16. The lower surface of the composite plate 16 is slidably connected to the upper surface of the transfer container 6.

[0053] Specifically, the transfer container 6 can support the sliding position of the support frame 10, and the support frame 10 is provided with a sample placement slot 11 to provide space for placing the sample storage box. The support frame 10 can support the rotation position of one end of the connecting rod 12, while the support plate 13 can support the rotation position of the other end of the connecting rod 12. When the transfer container 6 moves into the storage device 2 through the fully enclosed transmission channel 3, the magnetic repulsion force generated by the electromagnetic coil 18 in the storage device 2 can push the magnetic components 15 at both ends of the transfer container 6 to move outward, thereby driving the magnetic components 15 to move outward synchronously. The interior of the transfer container 6 is opened by the connecting plate 16, and the support frame 10 can be pulled to move by the connecting rod 12, thereby positioning it in the vertical position of the through slot 25, which is convenient for taking out and placing the sample.

[0054] Reference Figure 4 and Figure 6 A return spring 17 is fixedly connected to the outer wall of the support plate 13, and the outer wall of the return spring 17 is fixedly connected to the inner wall of the transfer container 6. A positioning plate 19 is slidably connected to the inner wall of the support frame 10, and a movable plate 21 is rotatably connected to the inner wall of the positioning plate 19. A connecting frame 22 is rotatably connected to the outer wall of the movable plate 21, and the outer wall of the connecting frame 22 is fixedly connected to the inner wall of the transfer container 6. A clamping plate 20 is fixedly connected to the upper surface of the positioning plate 19, and the clamping plate 20 is used to position the sample storage box on the inner wall of the sample placement slot 11.

[0055] Specifically, the support plate 13 provides fixed support for the return spring 17. After the transfer container 6 leaves the storage device 2, the return spring 17 rebounds, which can drive the guide plates 14 at both ends to close. The connecting plate 16 closes the transfer container 6, and the connecting rod 12 pushes the support frame 10 to slide in the opposite direction on the inner wall of the transfer container 6. When the positioning plate 19 moves, it drives the clamping plate 20 to slide in the inner wall of the sample placement slot 11 through the movable plate 21, thereby positioning the sample storage box in the sample placement slot 11. This ensures the stability of the sample during the transfer process, avoids excessive shaking, and improves the transfer quality.

[0056] Reference Figure 6 The transfer container 6 has a sliding connection to a push rod 23. One end of the push rod 23 is fixedly connected to a support frame 10, and the other end of the push rod 23 is fixedly connected to a fixing block 24. The outer wall of the fixing block 24 is set on the inner wall of the fully enclosed transfer channel 3.

[0057] Specifically, when the transfer container 6 moves to the position corresponding to the sampling slot 26, the fixing block 24 contacts the inner wall of the fully enclosed transmission channel 3, and pushes the support frame 10 to slide through the push rod 23, thereby causing the clamping plate 20 to detach from the outer wall of the sample storage box for easy retrieval. At the same time, after leaving the position of the sampling slot 26, it rebounds through the return spring 17, which can drive the clamping plate 20 to reposition the placed sample storage box again.

[0058] Reference Figure 1 The intelligent temperature and humidity coordinated control module includes an independent temperature control unit, an intelligent humidity control unit, and a predictive and adaptive control unit.

[0059] An independent temperature control unit is used to control and acquire data from each cooling plate and digital temperature sensor.

[0060] The intelligent humidity control unit is used to continuously monitor the humidity inside the storage module through a dew point sensor, and to reduce the humidity inside the chamber through a molecular sieve when the humidity is greater than 30%.

[0061] The prediction and adaptive control unit uses the collected humidity and temperature data as a dataset, and trains a long short-term memory network model based on the dataset to predict the trend of temperature and humidity changes, and dynamically adjusts the cooling power of the cooling plate and the working time of molecular sieve adsorption.

[0062] Specifically, the independent temperature control unit has cooling plates and digital temperature sensors installed on the six sides of the storage compartment, and they are connected to independent control circuits and data acquisition channels. Each cooling plate is controlled by a dedicated pulse width modulation controller, which adjusts the cooling power precisely by changing the duty cycle of the input voltage.

[0063] The intelligent humidity control unit monitors the humidity in the storage chamber in a comprehensive and real-time manner by evenly distributing dew point sensors inside the chamber. The collected humidity data is then used by the prediction and adaptive control unit to control the air intake and regeneration gas flow of the molecular sieve adsorption system, ensuring the high efficiency and stability of the dehumidification process.

[0064] The prediction and adaptive control unit organizes the temperature and humidity data collected over a period of time into a dataset in chronological order and normalizes the data to eliminate dimensional differences. Subsequently, this dataset is used to train a long short-term memory network model. By continuously adjusting the model parameters, the model performance is optimized. The trained model receives the latest temperature and humidity data in real time and predicts the temperature and humidity change trends in the future. Based on the prediction results, the system dynamically adjusts the cooling power of the cooling plate and the working time of the molecular sieve adsorption system, improving the timeliness of temperature and humidity control. Compared with traditional control methods, this significantly improves the system's energy efficiency and stability.

[0065] The intelligent temperature and humidity coordinated control module also includes a fault diagnosis unit, which is used to determine the operating faults of the cooling plate and molecular sieve by measuring the temperature and humidity change trends and the operating status of the cooling plate and molecular sieve, and to report the faults.

[0066] Specifically, the fault diagnosis unit continuously collects temperature and humidity data, as well as the operating current and voltage of the cooling plate, and the air intake and regeneration cycle operating parameters of the molecular sieve adsorption system. Once abnormal fluctuations occur in temperature and humidity, or the operating parameters of the cooling plate and molecular sieve deviate from the preset threshold, the fault location is located through six sides, and the fault information is reported to the maintenance personnel. This improves the reliability and stability of the entire intelligent temperature and humidity collaborative control module, ensuring the safety and stability of the ultra-low temperature biological storage environment.

[0067] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
