Description

Technical Field

[0001] The present invention relates to the technical field of biological cold chain, and specifically to an ultra-low temperature biological intelligent warehousing and logistics system. Background Art

[0002] In the fields of life science, medical pharmaceuticals, etc., the storage and transportation of ultra-low temperature biological samples are of utmost importance. These samples are extremely sensitive to temperature and humidity, and even minor environmental fluctuations can affect the sample activity, leading to deviations in research results or damage to the quality of medical products. At the same time, with the rapid development of biotechnology, the quantity and variety of samples are increasing continuously. Ultra-low temperature biological intelligent warehousing and logistics creates a safe, efficient, and intelligent warehousing and transportation environment for ultra-low temperature biological samples, promoting the steady progress of the biotechnology industry. Traditional transfer technologies mostly rely on manual opening of transfer containers.

[0003] However, in current technologies, the time taken for manual opening of the transfer container to complete the transfer each time is relatively long, which not only increases the sample exposure time but also affects the overall work efficiency. At the same time, during the opening and closing operations, a large amount of external hot air rushes in, causing strong heat exchange with the ultra-low temperature environment, and moisture condenses into frost on the surfaces of the container and the transmission channel, having an adverse impact on the sample quality.

[0015] Working principle: When storing or taking out a biological sample, first start the internal motor of the transfer container. The motor drives the gear to rotate, and drives the whole transfer container to move on the inner wall of the fully enclosed transfer channel through the rack. At the same time, the low-temperature nitrogen circulation pipe conducts the cold source to the inside of the transfer container through the heat conduction plate. At this time, when the transfer container moves to the position of the sealing plate, the fixed block contacts the inner wall of the fully enclosed transfer channel, squeezes the push rod, and the push rod can push the support frame to slide. At this time, the positioning plate slides outwards through the movable plate, pulls open the sealing plate, opens the sampling slot, and the sample storage box can be placed on the inner wall of the sample placement slot. Then close the sampling slot, and the return spring rebounds, driving the two end support plates to move towards the middle, thereby pushing the support frame to slide through the connecting rod, and the movable plate drives the clamping plate on the upper surface of the positioning plate to position the sample storage box, ensuring the stability of subsequent transportation; After that, when the transfer container is transported to one side of the fully enclosed transfer channel on the inner wall of the storage device, the electromagnetic coil generates a repulsive force on the magnetic component, which can drive the guide plates at both ends of the transfer container to slide outwards, thereby driving the closing plate to slide outwards 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 slot in the inner wall of the storage device for transfer, realizing the quick opening and closing actions of the transfer container, shortening the operation time, and reducing the risk of heat exchange and frosting.

[0016] The present invention provides a cryogenic biological intelligent warehousing and logistics system, which has the following beneficial effects: 1. In the present invention, an electromagnetic coil generates a repulsive force to drive the guide plates at both ends of the transfer container to slide outward, so that the composite plate slides outward synchronously on the upper surface, thereby opening the inner wall of the transfer container. Combined with a fully enclosed transmission channel, the transfer is completed, so as to quickly open and close the transfer container, shorten the operation time, reduce heat exchange, and reduce the risk of frosting.

[0017] 2. In the present invention, after the transfer container leaves the inside of the storage device, the return spring rebounds to drive the guide plates at both ends to close, and then the transfer container is closed through the composite plate. At the same time, the connecting rod pushes the support frame to slide reversely on the inner wall of the transfer container. When the positioning plate moves, the clamping plate is driven by the movable plate to slide on the inner wall of the sample placement groove to position the sample storage box in the groove, effectively avoiding excessive shaking of the sample during transfer and ensuring the stability and quality of transfer.

[0018] 3. The present invention collects temperature and humidity data and trains a long short-term memory network model. The trained model receives data in real time, predicts the change trend of temperature and humidity, and dynamically adjusts the power of the refrigeration plate and the working duration of the molecular sieve adsorption system according to the prediction, so as to improve the timeliness, energy saving and stability of regulation.

The transfer module is arranged on the inner wall of the fully enclosed transmission channel 3.

[0027] Specifically, the fully enclosed transfer channel 3 is arranged on the inner wall of the storage device 2, which can realize the operation of taking samples in a hermetically sealed temperature-controlled buffer space, avoiding the exposure of samples to the open environment. At the same time, the samples to be transferred can be transported outside the warehouse 1 through the fully enclosed transfer channel 3. The fully enclosed transfer channel 3 plays a role in fixedly supporting the guide rail 4, and at the same time, the guide rail 4 can support the position of the rack 5, facilitating the subsequent transfer work of the transfer module. At the same time, the fully enclosed transfer channel 3 can support the position of the low-temperature nitrogen circulation pipe 9. Through the low-temperature nitrogen circulation pipe 9, the transfer temperature inside the fully enclosed transfer channel 3 can be stabilized. The through groove 25 at one end of the fully enclosed transfer channel 3 facilitates the work of taking and storing samples inside the storage device 2.

At the same time, the sampling groove 26 can be opened and closed by the sealing plate 27 to ensure the sealing performance during the transfer inside the fully enclosed transfer channel 3.

[0028] Refer to Figure 6 and Figure 7 , the transfer module includes a transfer container 6. A gear 7 is arranged on the inner wall of the transfer container 6.

The lower surface of the transfer container 6 is fixedly connected to a heat conduction plate 8, and the lower surface of the heat conduction plate 8 is in contact with the upper surface of the low-temperature nitrogen circulation pipe 9.

[0029] Specifically, the transfer container 6 plays a role in fixedly supporting the gear 7, and a motor is embedded in the transfer container 6. The motor drives the gear 7 to rotate, so as to drive the whole transfer container 6 to carry out transfer work on the inner wall of the fully enclosed transfer channel 3 through the reverse force generated by the meshing connection with the rack 5. At the same time, the transfer container 6 plays a role in fixedly supporting the heat conduction plate 8. Through the transfer of the cold source between the heat conduction plate 8 and the low-temperature nitrogen circulation pipe 9, the constant low temperature inside the transfer container 6 can be maintained, reducing the temperature fluctuation during the transfer process.

[0030] Refer to Figure 6 , a support frame 10 is slidably connected to the inner wall of the transfer container 6. A sample placement groove 11 is opened inside the support frame 10 for placing a sample storage box. A connecting rod 12 is rotatably connected to the inner wall of the support frame 10. A support plate 13 is rotatably connected to the outer wall of the connecting rod 12. A guiding plate 14 is fixedly connected to the outer wall of the support plate 13.

[0031] 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 groove 11, providing a placement space for the sample storage box, and the support frame 10 can support the rotation position of one end of the connecting rod 12, and the support plate 13 can support the rotation position of the other end of the connecting rod 12. When the transfer container 6 moves to the inside of the storage device 2 through the fully enclosed transmission channel 3, the magnetic field 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, and the interior of the transfer container 6 is opened by the closing plate 16. At the same time, the support frame 10 can be pulled to move by the connecting rod 12, so as to be positioned to the vertical position of the through slot 25, which is convenient for taking and placing samples.

After the transfer container 6 leaves the interior of the storage device 2, the return spring 17 rebounds, which can drive the guide plates 14 at both ends to close, and the transfer container 6 is closed by the closing plate 16, 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 on the inner wall of the sample placement groove 11 through the movable plate 21, so as to position the sample storage box in the sample placement groove 11, thereby ensuring the stability of the sample during the transportation process, avoiding excessive shaking, and improving the transportation quality.

[0034] Specifically, when the transfer container 6 moves to the position corresponding to the sampling slot 26, the fixed block 24 contacts the inner wall of the fully enclosed transmission channel 3, and the support frame 10 is pushed to slide by the push rod 23, thereby driving the splint 20 to separate from the outer wall of the sample storage box for easy picking. At the same time, after leaving the position of the sampling slot 26, the reset spring 17 rebounds, and can drive the splint 20 again to position the placed sample storage box.

[0035] Referring to Figure 1 , the intelligent temperature and humidity collaborative control module includes an independent temperature control unit, an intelligent humidity regulation unit, and a prediction and adaptive regulation unit; The independent temperature control unit is used to respectively and independently control and collect data of each refrigeration plate and digital display temperature sensor through the refrigeration plate and the digital display temperature sensor; The intelligent humidity regulation unit is used to continuously monitor the humidity in the storage module through the dew point sensor, and when the humidity is greater than 30%, reduce the humidity in the warehouse through the molecular sieve; The prediction and adaptive regulation unit is used to take the collected humidity data and temperature data as a data set, and based on the data set, train a long short-term memory network model to predict the change trend of temperature and humidity, and dynamically adjust the refrigeration power of the refrigeration plate and the adsorption working duration of the molecular sieve.

[0036] Specifically, the independent temperature control unit installs a refrigeration plate and a digital display temperature sensor on six sides of the storage warehouse, and connects them to an independent control circuit and data acquisition channel. Each refrigeration plate is regulated by a dedicated pulse width modulation controller, and the accurate regulation of refrigeration power is achieved by changing the duty cycle of the input voltage; The intelligent humidity regulation unit uniformly arranges dew point sensors in the storage warehouse to comprehensively and real-time monitor the humidity in the warehouse. The collected humidity data is used to control the intake air volume and regeneration gas flow of the molecular sieve adsorption system through the prediction and adaptive regulation unit to ensure the efficiency and stability of the dehumidification process; The prediction and adaptive regulation unit sorts the temperature and humidity data collected within a period of time into a data set in chronological order, and normalizes the data to eliminate the dimension difference. Subsequently, these data sets are used to train the long short-term memory network model. By continuously adjusting the model parameters and optimizing the model performance, the trained model receives the latest temperature and humidity data in real time, predicts the change trend of temperature and humidity in the future period of time, and the system dynamically adjusts the refrigeration power of the refrigeration plate and the working duration of the molecular sieve adsorption system according to the prediction results, improving the timeliness of temperature and humidity regulation.

[0037] The intelligent temperature and humidity collaborative control module also includes a fault diagnosis unit. The fault diagnosis unit is used to judge the operation faults of the refrigeration plate and the molecular sieve through the change trend of temperature and humidity and the operation states of the refrigeration plate and the molecular sieve, and report the faults.

[0038] Specifically, the fault diagnosis unit continuously collects temperature and humidity data, obtains the working current and voltage of the refrigeration plate, as well as the intake air volume and regeneration cycle operation parameters of the molecular sieve adsorption system. Once abnormal fluctuations occur in the temperature and humidity changes, or the operation parameters of the refrigeration plate and molecular sieve deviate from the preset thresholds, the fault location is determined through six surfaces, and the fault information is reported to the operation and maintenance personnel, thereby improving the reliability and stability of the entire intelligent temperature and humidity collaborative control module and ensuring the safety and stability of the ultra-low temperature biological storage environment.
