As shown in table 1, the capacity of the first liquid nitrogen tank with the first difference information of-1 can only store 2 stem cells, if a plurality of current stem cells are stored in the first liquid nitrogen tank, at least two different liquid nitrogen tanks need to be opened, and at this time, liquid nitrogen in the two liquid nitrogen tanks needs to be volatilized simultaneously, so that the waste of liquid nitrogen is caused, and therefore, the optimal mode is to store a plurality of current stem cells which need to be stored in the same liquid nitrogen tank. Therefore, for the liquid nitrogen tank with the first difference information smaller than 0 or smaller than the first preset value, the present invention does not use the liquid nitrogen tank as the target liquid nitrogen tank, and uses the liquid nitrogen tank capable of storing all stem cells at one time as the target liquid nitrogen tank.
In an actual working scene, a plurality of liquid nitrogen tanks may exist to store a plurality of current stem cells at the same time, so the method preferably determines the liquid nitrogen tank with the minimum first difference information as the target liquid nitrogen tank, because the method can enable other liquid nitrogen tanks with more storage positions to be selected when used next time, if the liquid nitrogen tanks with more stem cells are stored next time, the corresponding liquid nitrogen tanks still have larger storage amount, and the method can dynamically distribute the stem cells to be stored according to the residual capacity of the liquid nitrogen tanks, so that each liquid nitrogen tank can store the stem cells which are the same as or are adaptive to the residual capacity of each liquid nitrogen tank in each stem cell storage process, further reduce the opening times of each liquid nitrogen tank in the liquid nitrogen storage system, and reduce the volatilization degree of the liquid nitrogen in the liquid nitrogen storage system.
And S140, acquiring two-dimensional data corresponding to the target liquid nitrogen tank in the stem cell position storage table at the current moment, wherein the two-dimensional data comprises layer occupation information of a basket in the target liquid nitrogen tank, and determining target layer address information based on the layer occupation information. In step S120, the data and information in the stem cell location storage table may exist in a decision tree manner, the grandchild node is a basket in the liquid nitrogen tank, at this time, the corresponding main body of the two-dimensional data is the basket, and the two-dimensional data may have layer occupation information and target layer address information of each layer in each basket. The structure of the decision tree is shown in fig. 2. The liquid nitrogen preservation system comprises S liquid nitrogen tanks, wherein T layers are arranged in a basket of each liquid nitrogen tank, and each layer can be used for placing at least one cryopreservation tube for stem cells. As shown in table 3, the stem cell location storage table may have the storage number of stem cells of the plurality of liquid nitrogen tanks at the current time, i.e., the first storage information, and the stem cell storage information of each layer in each basket in the liquid nitrogen tanks.
TABLE 3
Figure 911474DEST_PATH_IMAGE027
According to the technical scheme provided by the invention, the stem cell position storage table can be stored in the cloud server and modified based on the active control of an administrator, or the stem cell position storage table is updated and stored according to the stem cell position determination method provided by the invention, so that the stem cells of the stem cell position storage table at each moment are ensured to be corresponding to the layers of the liquid nitrogen tank and the lifting basket stored in the stem cells.
According to the technical scheme provided by the invention, after the target liquid nitrogen tank is obtained, layer occupation information of a basket in the target liquid nitrogen tank is determined, and target layer address information is determined based on the layer occupation information, wherein the layer occupation information comprises occupation conditions of all layers, for example, the storage quantity of stem cells of the layer 1 of the basket is 0, the layer 1 of the basket is not occupied at the moment, for example, the storage quantity of the stem cells of the layer E of the basket is 1, and the layer E of the basket is occupied at the moment. The layer occupation information in the invention is all the layer occupation information in the target liquid nitrogen tank, and the layer 1 of the basket and the layer E of the basket are layer addresses. The present invention will use the unoccupied layer as the target layer address information, for example, the storage number of stem cells in layer 1 of the basket is unoccupied, and the target layer address information includes layer 1, which may be a plurality of target layer address information.
In the technical solution provided by the present invention, as shown in fig. 3, step S140 specifically includes:
step S1401, layer total number information of the two-dimensional data is acquired. For example, the two-dimensional data of the basket corresponding to the target liquid nitrogen tank has 7 layers, and the layer total number information of the two-dimensional data is 7 layers, and the layer addresses corresponding to the two-dimensional data respectively include the 1 st layer, the 2 nd layer, … … and the 7 th layer.
Step S1402 determines layer occupation information of all layers occupied by stem cells at the current time. For example, when stem cells are placed on the layers 1 to 4, the layer occupancy information of all the layers at this time includes the occupancy of the layers 1 to 4.
Step S1403, obtaining unoccupied information according to the layer total number information and the layer occupation information, where the unoccupied information includes all unoccupied layer addresses. At this time, it is known that the total number of layers is from layer 1 to layer 7, the layer occupation information is from layer 1 to layer 4, and all unoccupied layer addresses included in the unoccupied information are from layer 5 to layer 7.
Step S1404, acquiring time remark information of all stem cells that need to be stored, and determining target layer address information based on the time remark information of the stem cells and label information of all unoccupied layer addresses. In the actual storage of stem cells, some stem cells are stored for a long time and are supplied to a patient after cell matching. Some stem cells are already distributed to corresponding patients, and the stem cells which are distributed to the patients can be extracted according to corresponding time when the operation date is reached, so that the transplantation operation is carried out on the patients, in the storage process of the stem cells, part of the stem cells have no fixed extraction date, and part of the stem cells have corresponding time remark information, for example, the time remark information is 1 month and 20 days 2022, and the corresponding stem cells, namely, the corresponding stem cells need to be extracted from a liquid nitrogen tank for processing on 1 month and 20 days 2022. When the target layer address information corresponding to each stem cell is selected, the target layer address information is distributed to the stem cells according to the time remark information of the stem cells, so that the stem cells with the time remark information are easier to extract in the corresponding liquid nitrogen tank, and the extraction efficiency of the stem cells is improved.
The label information may be the label of each layer in the basket, and the label information of the 1 st layer in the basket may be 1. When stem cells with time remark information appear, the invention preferentially selects the target layer address information with smaller label information, and the number of the selected target layer address information and the number of the stem cells needing to be stored are preferably the same. For example, 2 stem cells need to be stored, at this time, the layer 1, the layer 2, and the layer 5 of the basket in the target liquid nitrogen tank are not occupied, the numbers of the determined layers are 1 and 2, and the address information of the target layer is the layer 1 and the layer 2. Through the mode, in order to conveniently take the stem cells with the time remark information, the layer with the smaller label is selected, and the layer with the smaller label is closer to the opening of the liquid nitrogen tank, so that the layer with the smaller label is more beneficial to taking.
And S150, judging that a plurality of target layer address information are provided, distributing corresponding target layer address information to the stem cells needing to be stored based on the attribute information of each stem cell, and displaying the corresponding target layer address information of each stem cell. When a plurality of stem cells need to be stored, the corresponding target layer address information is also a plurality. The invention allocates the target layer address information to a plurality of stem cells respectively. Such that each stem cell has the appropriate stored target layer address information.
In the technical scheme provided by the invention, the step S150 specifically comprises the following steps:
selecting stem cells with time remark information to generate a first classification set, and sorting each stem cell in the first classification set according to the corresponding time remark information to obtain a first sorting result. When a plurality of stem cells are stored, the stem cells with time remark information are selected to generate a first classification set, for example, the total number of the stem cells needing to be stored is 3, wherein 2 stem cells have the time remark information, and the stem cells
Figure 101147DEST_PATH_IMAGE028
The time remark information is 2022 years, 1 month, 3 days, stem cells
Figure 469811DEST_PATH_IMAGE029
The time remark information is 2022, 1 month and 4 days, the first classification set at this time is the [ stem cells ]

The first sequencing result is the stem cell

。
Selecting stem cells without time remark information to generate a second classification set, and performing attribute information on each stem cell in the second classification set according to the corresponding attribute informationAnd sorting to obtain a second sorting result. Since there were only 1 stem cell without time-annotated information, the second set of classifications had only one stem cell
Figure 796363DEST_PATH_IMAGE031
. If there are a plurality of stem cells that do not have time remark information, the stem cells may be sorted according to their corresponding attribute information, where the attribute information may be attribute values configured in advance by an administrator for the stem cells, and the attribute values are, for example, 3, 4, and 5, and the attribute values corresponding to the stem cells that need to be stored at the same time are different.
And sequencing the address information of the target layers from top to bottom according to the layers of the hanging baskets corresponding to the address information of the target layers to obtain a third sequencing result. The present invention will obtain a plurality of target layer address information and then sort according to the layers, for example, the plurality of target layer address information are layer 1, layer 2 and layer 5, respectively, and then the third sorting result is layer 1-layer 2-layer 5.
And fusing the first sorting result and the second sorting result to obtain a total sorting result, wherein the last stem cell of the first sorting result is positioned in front of the first stem cell of the second sorting result in the total sorting result. The invention firstly fuses the first sequencing result and the second sequencing result, and the total sequencing result is the stem cell

And the stem cells in the total sorting result correspond to the layer address information in the third sorting result one by one according to the sorting sequence. The present invention will correlate the total ranking result with the third ranking result, at which time the stem cells are present
Figure 938445DEST_PATH_IMAGE034
That is, stem cells corresponding to layer 1

I.e. corresponding to layer 5.
Through the technical scheme, the storage layer of the corresponding stem cells in the target liquid nitrogen tank can be selected according to the time remark information of the stem cells, and the efficiency of a user in extracting the stem cells is improved.
The technical scheme provided by the invention further comprises the following steps:
and acquiring the rated capacity of each liquid nitrogen tank capable of accommodating the stem cells and the number of the stem cells with the time remark information. For example, the rated capacity of the liquid nitrogen tank for accommodating stem cells is 7, and the number of stem cells with time remark information in the liquid nitrogen tank is 2.
And obtaining the sequencing numerical value according to the rated capacity of the stem cells in the liquid nitrogen tank and the number of the stem cells with the time remark information. According to the method, sequencing numerical values can be obtained according to two dimensions of the rated capacity of the stem cells which can be contained in each liquid nitrogen tank and the number of the stem cells with time remark information, and the sequencing numerical value corresponding to each liquid nitrogen tank can be considered as a basis for sequencing the liquid nitrogen tanks.
And sequencing the traversal sequence of all the liquid nitrogen tanks based on the sequencing number to obtain a traversal sequencing result, wherein the traversal sequencing result is the sequence of traversing each liquid nitrogen tank when the storage position of any one stem cell is determined. For example, if there are 3 liquid nitrogen containers, the ranking value of the first liquid nitrogen container is 3, the ranking value of the second liquid nitrogen container is 4, and the ranking value of the third liquid nitrogen container is 5, the traversal order at this time is the third liquid nitrogen container-the second liquid nitrogen container-the first liquid nitrogen container.
When the staff need to carry out the ex-warehouse operation of the stem cells, the attribute information of the stem cells can be input into the collection equipment, and the attribute information of the stem cells can have unique identity information of each stem cell. Because the sequencing order of the liquid nitrogen tanks in the sequencing result is obtained according to the heat of the stem cells stored in the sequencing result, the probability that the liquid nitrogen tank of the stem cell with more storage time remark information is possibly selected is higher.
According to the technical scheme provided by the invention, the order number value obtained according to the rated capacity of the stem cells which can be accommodated in the liquid nitrogen tank and the number of the stem cells with the time remark information comprises the following steps:
Figure 685318DEST_PATH_IMAGE037
wherein the content of the first and second substances,
Figure 600185DEST_PATH_IMAGE012
is as follows

Figure 125341DEST_PATH_IMAGE015
in order to accommodate the nominal capacity of the stem cells,
Figure 843898DEST_PATH_IMAGE016
are the rank weight values. Because the rated capacity of each liquid nitrogen tank is different, the larger the capacity of the liquid nitrogen tank is, the more stem cells are possibly stored, the larger the capacity of the liquid nitrogen tank is during data traversal, the more corresponding stored data and information are, and therefore, when the sequencing numerical value of the liquid nitrogen tank is calculated, the method can prepare for the sequencing numerical value of the liquid nitrogen tank according to the timeThe number of the information-injected stem cells is compared with the ratio of the rated capacity capable of containing the stem cells, and the larger the ratio is, the larger the number of the stem cells with the time remark information in the liquid nitrogen tank is, the more the number of the stem cells needs to be compared and traversed first, so that the determining efficiency of the stem cell position is improved.
The target layer address information corresponding to the stem cells is displayed after being obtained, the user can check the target layer address information, and when the user thinks that the target layer address information corresponding to the stem cells is suitable for the current requirement and scene, the user can send the determined information to the equipment.
And step S160, based on the received determination information, the target layer address information and the attribute information corresponding to each stem cell are located in the stem cell position storage table for updating and storing.
