Description

Technical Field

[0001] The embodiments of the present disclosure relate to the fields of computer technology and temperature control, and more particularly to a precise temperature control method and device for a sample storage tank. Background Art

[0002] Biological samples often need to be stored in individually sealed sample tubes (specimen storage cans). Existing technical solutions use a passive cooling mode, which uses heat conduction from the can body to dissipate heat passively. This relies on the thermal conductivity of the can metal material to exchange heat with the external environment, without any active temperature control. Due to the temperature sensitivity of biological samples, when localized temperature anomalies (above a preset threshold) occur within the storage can, the passive cooling system suffers from low heat conduction efficiency and is unable to accurately control the temperature of the abnormal area.

[0003] The above information disclosed in this Background section is only for enhancement of understanding of the background of the inventive concept and therefore it may contain information that does not form the prior art that is already known to a person of ordinary skill in the art.

[0009] In a fourth aspect, some embodiments of the present disclosure provide a computer-readable medium having a computer program stored thereon, wherein when the program is executed by a processor, the method described in any implementation of the first aspect is implemented.

[0010] The above-described embodiments of the present disclosure have the following beneficial effects: The precise temperature control methods for sample storage tanks, as applied to some embodiments of the present disclosure, can improve heat conduction efficiency and precisely control the temperature of abnormal areas in a timely manner. Specifically, the passive heat dissipation system suffers from low heat conduction efficiency and is unable to precisely control the temperature of local abnormal areas because it relies on the thermal conductivity of the metal material of the tank body to exchange heat with the external environment, without an active temperature control device. Due to the temperature sensitivity of biological samples, when a local temperature abnormality (above a preset threshold) occurs within the storage tank, the passive heat dissipation system suffers from low heat conduction efficiency and is unable to precisely control the temperature of the local abnormal area. Based on this, the precise temperature control methods for sample storage tanks, as applied to some embodiments of the present disclosure, employ a matrix-arranged storage pipe and corresponding temperature sensors within the cylindrical tank body of the sample storage tank. This not only enables real-time monitoring of the storage temperature, but also creates more structured spaces through the matrix arrangement to facilitate precise temperature control. Furthermore, a fan-shaped nozzle assembly is provided at the bottom of the cylindrical tank body to spray positive pressure cold air. Specifically, first, in response to receiving pre-stored sample information, the current tank storage information of the sample storage tank is obtained. The pre-stored sample information includes a sample identifier and sample storage capacity, and the current tank storage information includes a sequence of storage channel occupancy information. Then, based on the pre-stored sample information and the current tank storage information, a storage channel of the sample storage tank is assigned to the sample to be stored corresponding to the sample identifier, thereby obtaining a target storage channel identifier group. Locating the target storage channel can be used to determine the storage location corresponding to the sample to be stored, thereby facilitating targeted temperature control. Next, the temperature values of each storage channel measured by a temperature sensor in the sample storage tank are received to obtain a sequence of channel temperature values. Based on this sequence of channel temperature values, temperature changes are predicted for the local area of the tank where the storage channel corresponding to the target storage channel identifier group is located, thereby generating a temperature change distribution matrix. This temperature change distribution matrix can be used to predict temperature changes of the sample before and after storage, thereby facilitating fine-grained temperature control. Next, based on the temperature change distribution matrix, the sample storage temperature control strategy information is generated, wherein the sample storage temperature control strategy information is information for adjusting the temperature of the storage pipeline. The sample storage temperature control strategy information includes a fan nozzle identification group and corresponding fan nozzle control information. The fan nozzle identification corresponds to the fan nozzle in the fan nozzle assembly in the sample storage tank. Here, by generating the sample storage temperature control strategy information, it can be used to accurately control the fan nozzle to spray cooling gas, so as to achieve the purpose of precise temperature control of the specified area. That is, through the sample storage temperature control strategy information, the corresponding fan nozzle is controlled to spray cooling gas into the sample storage tank to control the temperature of the area where the storage pipeline corresponding to the target storage pipeline identification group is located.This avoids the problem of poor heat dissipation in the sample storage tank due to abnormal temperatures, which can lead to low heat conduction efficiency. Furthermore, the goal of precise temperature control of the local abnormal area and various areas in the sample storage tank is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein.

[0025] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0026] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0027] Figure 1 The flowchart 100 of some embodiments of the precise temperature control method for a sample storage tank according to the present disclosure is shown. The cylindrical body of the sample storage tank is provided with storage pipes and corresponding temperature sensors arranged in a matrix, and a fan-shaped nozzle assembly is provided at the bottom of the cylindrical body.

[0028] Here, a high-density storage tube is arranged along the axis of the sample storage tank. The tubes are arranged vertically along the axis of the cylindrical tank. Considering that heat near the axis is difficult to dissipate through heat conduction, this solution uses horizontal heat conduction plates and vertical specialized storage tubes to quickly conduct heat near the axis to the outside.

[0029] As an example, Figure 2 As shown, multiple heat-conducting plates (gray elliptical areas) are arranged at equal heights within the sample storage tank. The heat-conducting plates can be made of copper, a material with high thermal conductivity. The plates are provided with holes of two different diameters. The smaller hole serves as the storage conduit 202. The larger hole serves as the reserved airflow channel 201.

[0030] Furthermore, considering that fixed air jets make it difficult to precisely control the temperature of specific areas, a fan-shaped nozzle assembly is installed at the bottom of the cylindrical tank. The fan-shaped nozzle is located at the positive pressure outlet at the bottom of the storage tank and is used to adjust the direction of the airflow. The fan-shaped nozzle assembly can include at least one fan-shaped nozzle.

[0031] For example, see Figure 3Schematic diagram of fan nozzle shown. Figure 3 It is shown in the figure that the direction of any fan-shaped nozzle can be adjusted in the working state to facilitate precise temperature control for different areas.

[0032] The precise temperature control method for a sample storage tank includes the following steps:

[0033] Step 101: In response to receiving pre-stored sample information, obtain current tank storage information of a sample storage tank.

[0034] In some embodiments, an entity (e.g., a computing device) executing a precise temperature control method for a sample storage tank can, in response to receiving pre-stored sample information, obtain the current tank storage information of the sample storage tank via a wired or wireless method. The pre-stored sample information can include a sample identifier and sample storage capacity, and the current tank storage information includes a sequence of storage channel occupancy information. The sample identifier can be a unique identifier for the sample to be stored. The sample storage capacity can be the number (or number of copies) of samples to be stored. Each piece of storage channel occupancy information corresponds to a storage channel, thereby facilitating determination of the occupancy status of each storage channel in the sample storage tank.

[0035] It should be noted that the computing device described above can be either hardware or software. When the computing device is hardware, it can be implemented as a distributed cluster consisting of multiple servers or terminal devices, or as a single server or a single terminal device. When the computing device is software, it can be installed in the hardware devices listed above. It can be implemented as multiple software or software modules, for example, to provide distributed services, or as a single software or software module. No specific limitations are given here.

[0036] Step 102 : Based on the pre-stored sample information and the current tank storage information, a sample storage tank storage pipeline is allocated to the sample to be stored corresponding to the sample identifier, and a target storage pipeline identifier group is obtained.

[0037] In some embodiments, the execution entity may allocate a sample storage tank storage pipeline to the sample to be stored corresponding to the sample identifier based on the pre-stored sample information and the current tank storage information to obtain a target storage pipeline identifier group.

[0038] In some optional implementations of some embodiments, the execution subject allocates a sample storage tank storage pipeline to the sample to be stored corresponding to the sample identifier based on the pre-stored sample information and the current tank storage information to obtain a target storage pipeline identifier group, which may include the following steps:

[0039] In the first step, based on the sample storage capacity in the pre-stored sample information, the samples to be stored corresponding to the sample identifiers are divided into storage channels to determine the number of storage channel occupancy. The sample storage capacity can be divided into multiple portions based on the sample capacity that can be stored in each storage channel. The number of portions thus divided is determined as the storage channel occupancy.

[0040] The second step is to use the storage pipe occupancy information sequence included in the current tank storage information to mark occupied storage pipes in the initial storage pipe planar array diagram, thereby obtaining a current planar array diagram. The storage pipe planar array diagram is a planar diagram corresponding to the arrangement of each storage pipe within the cylindrical tank. The storage pipe planar array diagram includes a storage pipe identification sequence and a corresponding storage pipe occupancy identification sequence. The storage pipe occupancy identification sequence indicates whether the corresponding storage pipe is occupied.

[0041] The third step is to mark the jet coverage area corresponding to each fan-shaped nozzle in the current planar array diagram, obtaining a marked planar array diagram. Each fan-shaped nozzle has a corresponding circular jet coverage area due to the jet angle restriction. Therefore, the jet coverage area corresponding to each fan-shaped nozzle can be marked in the current planar array diagram, centered on the fan-shaped nozzle location and with the nozzle's maximum deflection direction as the radius, to obtain a marked planar array diagram.

[0042] In practice, considering that the airflow coverage area of each fan nozzle is circular, and that multiple circular areas are far apart, there are areas that are difficult to reach. Therefore, the fan nozzle positions are pre-set according to their coverage radius, so that the airflow coverage areas of each fan nozzle overlap, greatly reducing the areas that are difficult to reach. This facilitates precise temperature control of the designated area.

[0043] As an example, Figure 4 Schematic diagram of fan nozzle distribution shown. Figure 4 The black dot in the cross section 403 of the storage tank indicates the center point of the fan-shaped nozzle (i.e., the positive pressure outlet 401). The circular dotted line indicates the jet coverage area (jet coverage range 402) centered on the fan-shaped nozzle. Figure 4 As can be seen, the multiple jet coverage areas in the center of the tank overlap, minimizing uncovered areas and ensuring full coverage of the central area. Furthermore, while some blank areas still exist at the edges, since these blank areas are at the tank's boundaries and the jet coverage areas of the fan-shaped nozzles at the edges extend beyond the tank, the cooling gas ejected from the fan-shaped nozzles can flow back through the tank's inner walls, diffusing into the blank areas. This achieves full coverage of each storage pipe 202. Figure 4The right sub-figure shows a schematic diagram of the structure within an air jet coverage area (the air flow pipe is not shown). The blank dots in the sub-figure represent storage pipes 202.

[0044] The fourth step is to allocate storage pipelines to the area where the unoccupied storage pipelines are located in the above-mentioned marked plane array diagram, so as to select a storage pipeline area that meets the above-mentioned storage pipeline occupation number, and determine the individual storage pipeline identifiers within the above-mentioned storage pipeline area as the target storage pipeline identifier group. In this step, the storage pipeline arrangement diagram corresponding to the samples to be stored with the above-mentioned storage pipeline occupation number is determined according to a preset arrangement method (for example, a centralized arrangement method). For example, the number of occupied storage pipelines is five. Then, according to the preset arrangement method, five adjacently arranged storage pipelines can be occupied, and thus the position box of the five storage pipelines can be determined as the storage pipeline arrangement diagram. Then, within the area of the unoccupied storage pipelines in the above-mentioned marked plane array diagram, storage pipelines are allocated to the above-mentioned storage pipeline arrangement diagram using a preset allocation algorithm to obtain a storage pipeline area. Finally, the individual storage pipeline identifiers within the above-mentioned storage pipeline area are determined as the target storage pipeline identifier group.

[0045] As examples, the allocation algorithms mentioned above may include, but are not limited to, at least one of the following: collision detection, simulated annealing, and the largest empty circle algorithm. Furthermore, if the storage pipelines are already heavily occupied and cannot be allocated to the corresponding storage pipeline areas using the pre-set arrangement, the arrangement can be adjusted and reallocated. For example, a straight-line or L-shaped arrangement can be used.

[0046] In practice, if samples are stored separately during the sample storage process, the thermal interactions during the storage process and the original temperature of the samples can easily affect the temperatures of other nearby storage pipes. This can increase the impact on other storage pipes and easily damage the samples there due to temperature fluctuations. Therefore, the allocated samples can be arranged and stored centrally according to a specific arrangement. This not only reduces the impact on other storage pipes but also allows for centralized temperature control of the storage pipe area, thereby improving temperature control accuracy. Furthermore, by pre-setting fan nozzles and corresponding jet coverage areas at different locations, the storage pipe areas of the samples to be stored can be stored within the same jet coverage area as much as possible. Therefore, precise local temperature control can be achieved by adjusting the cooling gas ejection direction and velocity solely through the fan nozzle corresponding to the jet coverage area. Furthermore, there is no need to control all fan nozzles simultaneously. This reduces the temperature control area and reduces energy consumption.

[0047] Step 103: receiving the pipe temperature values measured by the temperature sensor in the sample storage tank for each storage pipe, and obtaining a pipe temperature value sequence.

[0048] In some embodiments, the execution entity may receive pipe temperature values measured by a temperature sensor in the sample storage tank for each storage pipe, thereby obtaining a sequence of pipe temperature values. The temperature sensor may be a patch-type temperature sensor attached to the outer wall of each storage pipe. Each pipe temperature value corresponds to a storage pipe.

[0049] Step 104 : Based on the pipeline temperature value sequence, temperature variation prediction is performed on the local area of the tank where the storage pipeline corresponding to the target storage pipeline identification group is located, so as to generate a temperature variation distribution matrix.

[0050] In some embodiments, the execution entity may perform temperature change prediction on a local area of the tank where the storage pipeline corresponding to the target storage pipeline identification group is located based on the pipeline temperature value sequence to generate a temperature change distribution matrix.

[0051] In some optional implementations of some embodiments, the execution subject performs temperature change prediction on a local area of the tank where the storage pipeline corresponding to the target storage pipeline identification group is located based on the pipeline temperature value sequence to generate a temperature change distribution matrix, which may include the following steps:

[0052] The first step is to determine the heat exchange duration of the sample to be stored corresponding to the above-mentioned sample identification according to the above-mentioned target storage pipe identification group. The above-mentioned heat exchange duration represents the opening time of the sample storage tank during the storage process of the sample to be stored. Secondly, the single storage duration corresponding to the above-mentioned sample identification can be obtained from the preset storage table. The single storage duration can be the duration required to store a sample to be stored. The storage table can include single storage durations set for different samples. Therefore, the product of the number of storage pipe occupancy and the above-mentioned single storage duration can be determined as the heat exchange duration.

[0053] In practice, considering that the sample storage process can easily lead to heat exchange between the internal and external spaces of the sample storage tank, the duration of the heat exchange process can be characterized by determining the storage duration of each sample during the entire storage process.

[0054] In the second step, the temperature values of the samples to be stored and the heat exchange duration are used to determine the temperature change of the storage pipes corresponding to the target storage pipe identification group, thereby obtaining a temperature change sequence. The external ambient temperature of the sample storage tank can be obtained. The external ambient temperature, the temperature value to be stored, and the heat exchange duration can then be input into a preset temperature prediction model to determine the temperature change of the storage pipes corresponding to the target storage pipe identification group, thereby obtaining a temperature change sequence.

[0055] For example, a temperature prediction model could be the heat conduction equation. In practice, because the temperature of the sample to be stored differs from the temperature of the storage pipe, this model can be used to predict the temperature change of each storage pipe within the storage pipe area after the sample is stored. Each temperature change corresponds to a storage pipe and represents the temperature value after the change.

[0056] The third step is to mark the heat conduction area corresponding to the target storage pipe identification group in the above-mentioned marked plane array diagram, and determine the above-mentioned heat conduction area and the storage pipe area corresponding to the target storage pipe identification group as the local area of the tank body. In particular, it is taken into account that the storage pipe where the sample to be stored is stored will have temperature changes, and at the same time, the temperature changes will occur in other surrounding storage pipes. Therefore, first, the associated storage pipes after the sample to be stored is stored in the storage pipe can be determined, that is, other storage pipes that will be affected by the temperature. Then, the area where each associated storage pipe and the storage pipe corresponding to the sample to be stored are located can be determined as the heat conduction area. Here, the temperature difference between the temperature change of the storage pipe corresponding to the target storage pipe identification and the other adjacent storage pipes can be determined. If the temperature difference is greater than the first preset temperature difference threshold, the other adjacent storage pipes are determined as the associated storage pipes.

[0057] Additionally, other adjacent storage pipes can be used as first-tier pipes outside the storage pipe area. A second preset temperature difference threshold can be used to determine whether adjacent second-tier pipes should be used as associated storage pipes. Here, because the distance between the second-tier pipes and the storage pipe area is greater than the distance between the first-tier pipes and the storage pipe area, the second preset temperature difference threshold is set to be lower than the first preset temperature difference threshold.

[0058] The fourth step is to predict the temperature changes of each storage pipe in the local area of the tank body based on the above-mentioned pipeline temperature value sequence and the above-mentioned heat change sequence to generate a temperature change distribution matrix. The above-mentioned temperature change distribution matrix is used to characterize the temperature changes of each storage pipe in the local area of the tank body. Secondly, the temperature change time point to be predicted can be pre-selected. For example, the temperature change time point can be a time point after the heat exchange duration. In practice, the temperature change duration, the above-mentioned pipeline temperature value sequence and the above-mentioned heat change sequence can be input into the above-mentioned temperature prediction model to predict the temperature changes of each storage pipe in the local area of the tank body to generate a temperature change distribution matrix. Here, the temperature change distribution matrix can be a rectangular matrix. The outer frame of the rectangular matrix can be the minimum external bounding box of the local area of the tank body. The temperature change distribution matrix can characterize the temperature values corresponding to each storage pipe within the minimum external bounding box. The two-dimensional coordinate position of each matrix value in the temperature change distribution matrix corresponds to the pipe position of the storage pipe arranged in the tank body.

[0059] In practice, the temperature changes before and after sample storage are first considered, as is the difference in thermal conductivity between the sample to be stored and the storage pipes, and between the storage pipes themselves. Therefore, two temperature change predictions are performed to predict the temperature changes in local areas of the tank. This temperature prediction model then uses to predict the temperature of each storage pipe within the heat transfer area, allowing for pre-emptive adjustments to fan nozzles for local temperature control, thus avoiding significant temperature differences before and after sample storage that could damage the sample.

[0060] Step 105: Generate sample storage temperature control strategy information based on the temperature change distribution matrix.

[0061] In some embodiments, the execution entity may generate sample storage temperature control strategy information based on the temperature change distribution matrix. The sample storage temperature control strategy information is information used to adjust the storage pipeline temperature. The sample storage temperature control strategy information may include a fan nozzle identification group and corresponding fan nozzle control information, where the fan nozzle identification corresponds to a fan nozzle in the fan nozzle assembly in the sample storage tank.

[0062] In some optional implementations of some embodiments, the execution entity generates sample storage temperature control strategy information according to the temperature change distribution matrix, which may include the following steps:

[0063] In the first step, in response to the local area of the tank being within an air jet coverage area in the marked plane array diagram, a corresponding first fan-shaped nozzle identifier is determined. The local area of the tank being within an air jet coverage area in the marked plane array diagram can indicate that the local area of the tank corresponds to the air jet coverage area of only one fan-shaped nozzle.

[0064] In the second step, based on the temperature change distribution matrix, the fan nozzle corresponding to the first fan nozzle identifier is analyzed for its jet strategy to generate first sample storage temperature control strategy information, and the first sample storage temperature control strategy information is determined as the sample storage temperature control strategy information. The first sample storage temperature control strategy information includes a first circulation path and a first wind force value sequence. The first sample storage temperature control strategy information can be generated by the following steps: First, the highest temperature value can be selected from the temperature change distribution matrix, and the corresponding two-dimensional coordinates of the storage pipe can be determined as the highest temperature coordinates. Then, the storage pipes whose temperature difference from the highest temperature is a first preset temperature difference can be selected as temperature difference limit pipes. Then, the line connecting the temperature difference limit pipes can be determined as the first circulation path of the fan nozzle. Next, the width of the first circulation path to the boundary of the tank area can be determined to obtain a width value sequence. The wind force value of the fan nozzle at each position along the first circulation path can be calculated based on the width values to obtain a first wind force value sequence. Here, the first wind force value = base wind force value × (width value / base width value). Here, if the output first wind force value is less than the basic wind force value, the basic wind force value is determined as the first wind force value. Finally, the first patrol path and the first wind force value sequence can be determined as the first sample storage temperature control strategy information.

[0065] Optionally, the execution entity generates sample storage temperature control strategy information according to the temperature change distribution matrix, and may further include the following steps:

[0066] In the first step, in response to the partial area of the tank being outside of one of the jet coverage areas in the marked plane array diagram, a corresponding second fan-shaped nozzle identification group is determined. The partial area of the tank being outside of one of the jet coverage areas in the marked plane array diagram may indicate that the partial area of the tank intersects multiple jet coverage areas.

[0067] In the second step, according to the above-mentioned temperature change distribution matrix, the fan nozzles corresponding to the second fan nozzle identifiers in the above-mentioned second fan nozzle identifier group are subjected to jet strategy analysis to generate second sample storage temperature control strategy information, and the above-mentioned second sample storage temperature control strategy information is determined as the sample storage temperature control strategy information. Among them, the above-mentioned second sample storage temperature control strategy information includes a second circuit path sequence and a second wind force value sequence set. Secondly, the second sample storage temperature control strategy information can be generated in the following manner: First, the first circuit path and the first wind force value sequence can be determined through the generation process of the above-mentioned first sample storage temperature control strategy information. Then, the first circuit path can be segmented according to the nozzle coverage area corresponding to the second fan nozzle identifier to obtain a second circuit path sequence. At the same time, the first wind force value sequence can be divided according to the segmentation position of the second circuit path sequence to obtain a second wind force value sequence set. Finally, the second circuit path sequence and the second wind force value sequence set can be determined as the second sample storage temperature control strategy information. The second circuit path corresponds to the second fan nozzle identifier.

[0068] Step 106 : Control the corresponding fan-shaped nozzle to spray cooling gas toward the sample storage tank according to the sample storage temperature control strategy information, so as to control the temperature of the area where the storage pipe corresponding to the target storage pipe identification group is located.

[0069] In some embodiments, the execution entity may control the corresponding fan-shaped nozzle to spray cooling gas into the sample storage tank according to the sample storage temperature control strategy information, so as to control the temperature of the area where the storage pipe corresponding to the target storage pipe identification group is located.

[0070] In some optional implementations of some embodiments, the execution subject controls the corresponding fan-shaped nozzle to spray cooling gas into the sample storage tank based on the sample storage temperature control strategy information to control the temperature of the area where the storage pipe corresponding to the target storage pipe identification group is located, which may include the following steps:

[0071] The first step is to control the corresponding fan-shaped nozzle to rotate in direction and start to spray cooling gas according to the temperature control strategy information stored in the above sample, or to control the fan-shaped nozzle corresponding to the above second fan-shaped nozzle identification group to rotate in direction and start to spray cooling gas according to the temperature control strategy information stored in the above second sample.

[0072] As an example, the first fan-shaped nozzle identifier can be used to start the corresponding fan-shaped nozzle, adjust the jet direction of the fan-shaped nozzle according to the first patrol path in the temperature control strategy information stored in the first sample, and adjust the corresponding jet speed according to the corresponding first wind force value sequence, so as to accurately control the temperature of the local area of the tank.

[0073] As another example, the second fan-shaped nozzle identification group can be used to start the corresponding multiple fan-shaped nozzles, and the jet direction of the fan-shaped nozzle can be synchronously adjusted according to the second patrol path sequence in the second sample storage temperature control strategy information, and the corresponding jet speed can be adjusted according to the corresponding second wind force value sequence, so as to accurately control the temperature of the local area of the tank. Here, when multiple fan-shaped nozzles are adjusted at the same time, they can be controlled synchronously. The travel speed of the fan-shaped nozzle (that is, the speed of changing the jet direction) can be fixed or variable. In addition, before starting, the coordinates of the first patrol path and the second patrol path can also be converted into the jet direction of the fan-shaped nozzle. For example, determine the storage pipe identification corresponding to a certain position on the path, and then determine the direction of the bottom of the storage pipe corresponding to the identification relative to the fan nozzle as the jet direction.

[0074] The second step is to control the temperature sensor to measure the real-time temperature of the storage pipe in the local area of the tank body to obtain a real-time temperature value sequence of the storage pipe.

[0075] The third step is to adjust the control strategy information of the fan nozzle corresponding to the first fan nozzle identifier or the fan nozzle corresponding to the second fan nozzle identifier group according to the above-mentioned real-time temperature value sequence of the storage pipeline, and adjust the rotation direction of the corresponding fan nozzle according to the adjusted control strategy information, so as to control the temperature of the area where the storage pipeline corresponding to the above-mentioned target storage pipeline identifier group is located. If the difference between the real-time temperature value of the storage pipeline at the location of the first or second circuit path and the above-mentioned highest temperature value is less than the target temperature difference threshold, the first or second circuit path can be adjusted again through the above-mentioned step of generating the storage temperature control strategy information. And the rotation direction of the corresponding fan nozzle is adjusted according to the adjusted first or second circuit path. So as to accurately control the temperature of the area where the storage pipeline corresponding to the above-mentioned target storage pipeline identifier group is located.

[0076] In practice, as the dry cooling gas is ejected from the fan-shaped nozzle, the storage pipes in the local area of the tank will gradually cool down. When the temperature drops to a certain level, the spray direction of the fan-shaped nozzle can be adjusted to further bias it toward the central area with relatively higher temperature, so as to continue to perform precise temperature control.

[0077] Furthermore, considering that the gas ejected from the positive pressure outlet (i.e., fan-shaped nozzle) is unidirectional, its circulation effect is poor. Therefore, within the jet coverage area of a single fan-shaped nozzle, several storage pipes are evenly distributed along the axis. Raised spiral guide patterns are added to the exterior of these selected storage pipes. These patterns create a swirling motion in the airflow from the positive pressure outlet, creating a cyclonic effect, thereby improving temperature control efficiency.

[0078] As an example, refer to Figure 5The left side of the figure shows the area covered by the jet of a fan-shaped nozzle. The small black dots marked in the area are evenly selected storage pipes, which are provided with spiral lines 501 to form a special storage pipe 502 with spiral lines. The spiral lines can be as follows: Figure 5 As shown in the figure on the right side of the middle, the ordinary storage pipe 202 is not provided with the spiral pattern 501.

[0079] In practice, reference Figure 6 The sample storage tank shown in the figure. Positive-pressure outlets are arranged in zones at the bottom of the tank to blow out dry, low-temperature, cold air at a constant temperature. A negative-pressure intake port is located in the center of the tank lid (top of the tank), creating a one-way convection flow of the low-temperature cold air within the tank. The dashed lines in the figure are schematic indicators of the gas flow within the tank.

[0080] Optionally, the above execution entity may further perform the following steps:

[0081] The first step is to perform temperature detection on the aforementioned pipeline temperature value sequence and, in response to detecting an abnormal pipeline temperature value in the aforementioned pipeline temperature value sequence, generate sample abnormal temperature control strategy information. The temperature detection may be detecting an abnormal pipeline temperature value in the aforementioned pipeline temperature value sequence. Here, the abnormal temperature may be a difference between the pipeline temperature value and the average temperature value that is greater than a preset difference. Secondly, the sample abnormal temperature control strategy information may be generated using the aforementioned method for generating sample stored temperature control strategy information.

[0082] As an example, Figure 7 A schematic diagram of abnormal temperature inside a sample storage tank is shown. The red area in the figure indicates the abnormal temperature area.

[0083] In the second step, the abnormal temperature control strategy information of the sample is used to control the corresponding fan-shaped nozzle to spray cooling gas into the sample storage tank to control the temperature of the area where the target storage pipeline is located.

[0084] In practice, the above-mentioned horizontal (heat conduction plate) and vertical heat conduction technologies are combined to realize a three-dimensional heat dissipation network in the storage tank. Combined with the gas circulation convection technology, abnormal heat in the storage tank can be quickly discharged to maintain a constant temperature environment in the tank.

[0085] The above-described embodiments of the present disclosure have the following beneficial effects: The precise temperature control methods for sample storage tanks, as applied to some embodiments of the present disclosure, can improve heat conduction efficiency and precisely control the temperature of abnormal areas in a timely manner. Specifically, the passive heat dissipation system suffers from low heat conduction efficiency and is unable to precisely control the temperature of local abnormal areas because it relies on the thermal conductivity of the metal material of the tank body to exchange heat with the external environment, without an active temperature control device. Due to the temperature sensitivity of biological samples, when a local temperature abnormality (above a preset threshold) occurs within the storage tank, the passive heat dissipation system suffers from low heat conduction efficiency and is unable to precisely control the temperature of the local abnormal area. Based on this, the precise temperature control methods for sample storage tanks, as applied to some embodiments of the present disclosure, employ a matrix-arranged storage pipe and corresponding temperature sensors within the cylindrical tank body of the sample storage tank. This not only enables real-time monitoring of the storage temperature, but also creates more structured spaces through the matrix arrangement to facilitate precise temperature control. Furthermore, a fan-shaped nozzle assembly is provided at the bottom of the cylindrical tank body to spray positive pressure cold air. Specifically, first, in response to receiving pre-stored sample information, the current tank storage information of the sample storage tank is obtained. The pre-stored sample information includes a sample identifier and sample storage capacity, and the current tank storage information includes a sequence of storage channel occupancy information. Then, based on the pre-stored sample information and the current tank storage information, a storage channel of the sample storage tank is assigned to the sample to be stored corresponding to the sample identifier, thereby obtaining a target storage channel identifier group. Locating the target storage channel can be used to determine the storage location corresponding to the sample to be stored, thereby facilitating targeted temperature control. Next, the temperature values of each storage channel measured by a temperature sensor in the sample storage tank are received to obtain a sequence of channel temperature values. Based on this sequence of channel temperature values, temperature changes are predicted for the local area of the tank where the storage channel corresponding to the target storage channel identifier group is located, thereby generating a temperature change distribution matrix. This temperature change distribution matrix can be used to predict temperature changes of the sample before and after storage, thereby facilitating fine-grained temperature control. Next, based on the temperature change distribution matrix, the sample storage temperature control strategy information is generated, wherein the sample storage temperature control strategy information is information for adjusting the temperature of the storage pipeline. The sample storage temperature control strategy information includes a fan nozzle identification group and corresponding fan nozzle control information. The fan nozzle identification corresponds to the fan nozzle in the fan nozzle assembly in the sample storage tank. Here, by generating the sample storage temperature control strategy information, it can be used to accurately control the fan nozzle to spray cooling gas, so as to achieve the purpose of precise temperature control of the specified area. That is, through the sample storage temperature control strategy information, the corresponding fan nozzle is controlled to spray cooling gas into the sample storage tank to control the temperature of the area where the storage pipeline corresponding to the target storage pipeline identification group is located.This avoids the problem of poor heat dissipation in the sample storage tank due to abnormal temperatures, which can lead to low heat conduction efficiency. Furthermore, the goal of precise temperature control of the local abnormal area and various areas in the sample storage tank is achieved.
