[0054] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings.

[0055] In the description of this specification, the description with reference to the terms "certain embodiments", "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiments or examples are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0056] The present application embodiment discloses an ultra-low temperature refrigerator sample intelligent management system, referring to Figure 1 , including personnel and organizational structure management module, refrigerator space planning management module, refrigerator space allocation management module, refrigerator space usage tracking management module, refrigerator security access management module and refrigerator security status management module.

[0057] Personnel and organizational structure management module, refer to Figure 2 , used to receive architecture setting request information, create a research group based on the architecture setting request information, and configure the permissions corresponding to the researcher roles in the research group.

[0058] Refrigerator space planning and management module, refer to Figure 3 , used to link the refrigerators for sample storage, and divide and quantify the structure of each refrigerator in terms of layers, freezing racks and freezing boxes; it is clear how many freezing boxes each refrigerator can store. The refrigerator provides a visual interface to display the internal structure of the refrigerator and the current usage.

[0059] The refrigerator space allocation management module is used to receive the sample registration information of the researchers currently using it, and is based on the structure divided by the refrigerator space planning management module. According to the sample registration information, the cryopreservation boxes are allocated according to the preset allocation rules; after the allocation is completed, the refrigerator space planning management module updates the sample storage information; wherein, the sample registration information includes the storage of the cryopreservation boxes.

[0060] The refrigerator space usage tracking management module is used to receive the cryobox application information of the researcher currently using it, and determine whether to execute the request corresponding to the cryobox application information based on the usage status of the previously allocated cryoboxes and according to the preset judgment rules. The cryobox application information includes depositing, taking out or taking away the cryoboxes.

[0061] The refrigerator security access management module is used to verify the identity information of the researcher currently using it and determine whether the refrigerator currently stores the cryopreservation boxes associated with the researcher. If so, the refrigerator is unlocked after verification; otherwise, the refrigerator is locked.

[0062] The refrigerator safety status management module is connected to the intranet server and is used to monitor the working parameters in the refrigerator, such as temperature, humidity, voltage, current, etc. If the working parameters are abnormal, an alarm will be issued.

[0063] Reference Figure 2 , the researcher roles include platform administrator, project group administrator and ordinary student. The platform administrator's permissions include the permission to create a project group and the permission to set the permissions of the project group administrator. The permissions of the project group administrator include the permission to add a refrigerator and plan the internal structure of the refrigerator, and the permission to set the permissions of ordinary students to operate the refrigerator. The permissions of ordinary students include the permission to apply for cryoboxes and register sample information. The refrigerator is equipped with a card swiping device or a face swiping device, and researchers can access cryoboxes by swiping cards or face swiping on the refrigerator.

[0064] As the owner of the highest authority, the platform administrator can create research groups and set the authority of the research group administrator. However, they are not directly involved in the operation of the refrigerator or the storage and access of samples. The research group administrator is responsible for managing a specific research group, including adding refrigerators, planning the internal structure of the refrigerator, and setting the authority of ordinary students to operate the refrigerator. That is, only students authorized by the research group administrator can access the cryoboxes in the refrigerator by swiping a card or scanning a face. The authority of ordinary students is relatively low, mainly limited to applying for cryoboxes and registering sample information. However, with the authorization of the research group administrator, they can access the refrigerator by swiping a card or scanning a face.

[0065] Reference Figure 3 and Figure 4 , where the allocation rules in the refrigerator space allocation management module are as follows:

[0066] The first method: The allocation rules include allocation according to the active application method of the current researcher (user): obtain the application information added by the current researcher, and the application information includes the application quantity of cryopreservation boxes. The user submits the application through the mobile terminal or the web terminal, and the application information includes the required number of cryopreservation boxes.

[0067] The project administrator of the project group to which the current researcher belongs reviews the researcher's application information; if the application information is approved, the corresponding numbered refrigerator is selected first, and then the location of the cryobox is selected. The method of selecting the corresponding numbered refrigerator includes automatically and randomly assigning a refrigerator with any number or a refrigerator with a specified number. The system is provided with a one-key automatic assignment operation to automatically complete the entire process from refrigerator selection to cryobox location assignment. The method of selecting the location of the cryobox includes randomly assigning the location of the cryobox in the selected refrigerator, or specifying the layer or cryorack of the cryobox in the selected refrigerator, and then randomly assigning the location of the cryobox.

[0068] After the user's project group administrator reviews and approves the application, the cryobox location can be automatically allocated with one click, or a specific refrigerator can be specified to automatically allocate the cryobox location, or a specific refrigerator or refrigerator layer can be specified to automatically allocate the cryobox location. This allocation method fully considers the actual needs of researchers and the management authority of the project group administrator. Through flexible refrigerator and cryobox location selection methods and convenient allocation operations, the efficiency of refrigerator space utilization and the convenience of management can be effectively improved. At the same time, the review mechanism of the project group administrator also ensures the rationality of allocation and the effective use of resources.

[0069] Reference Figure 5 and Figure 6 The refrigerator includes a display touch screen for displaying relevant data of the frozen boxes in the refrigerator.

[0070] The second method: the allocation rules include the allocation method in which the research group administrator actively allocates the cryobox: the research group administrator selects a single unused cryobox on the display touch screen according to the display results of the display touch screen, and adds the researcher's information. The research group administrator can view all the free positions on the refrigerator visualization page, and then add the cryobox user information to the position of the designated cryobox, and allocate the cryobox individually. The research group administrator can intuitively view all the free cryobox positions through the refrigerator visualization page of the system.

[0071] The third method: Allocation rules include batch allocation of cryoboxes: The project group administrator imports a table that stores refrigerator location information and matching researchers into the system. The system automatically recognizes and parses the imported table content. This includes reading refrigerator location information, researcher information, and the matching relationship between them. The system recognizes the table with one click and allocates cryoboxes in batches according to the matching relationship between cryoboxes and researchers.

[0072] The project administrator first organizes the refrigerator location and user information in an Excel spreadsheet, then imports it into the system with one click to batch allocate cryoboxes. The batch allocation of cryoboxes greatly improves the allocation efficiency, especially when a large number of cryoboxes need to be allocated. By preparing a simple spreadsheet, the project administrator can quickly complete the allocation work without having to manually select refrigerator locations and add researcher information one by one. In addition, this method reduces the possibility of human error and improves the accuracy of allocation.

[0073] When the user applies for a cryopreservation box again, whether the administrator needs to issue or allocate space requires a judgment rule. This judgment rule includes: judging whether the cryopreservation box allocated based on the sample registration information is in use and whether the cryopreservation box is effectively utilized; if it is in use or effectively utilized, the request corresponding to the cryopreservation box application information is executed; otherwise, the request corresponding to the cryopreservation box application information is not executed.

[0074] How to obtain the usage status of the cryopreservation box? The system designs a tracking mechanism for the usage status of the cryopreservation box, which mainly collects information from two aspects.

[0075] Reference Figure 5 The first aspect is whether the cryopreservation boxes are stored in the refrigerator, the refrigerator is locked, and a touch panel is installed; some new refrigerators have touch screens that can install programs on the panel, and install customized programs to achieve interactive functions. Every time a user uses the refrigerator, he first swipes his card or face on the panel for personnel authentication, and then selects the purpose of using the refrigerator this time, whether to deposit a cryopreservation box, take out a cryopreservation box, or take away a cryopreservation box. Then select the cryopreservation box that needs to be operated, and the system will graphically display the location of the cryopreservation box on the panel. The user deposits or takes out the cryopreservation box according to the specific location given.

[0076] Reference Figure 6 , Secondly, the storage status of samples in the cryopreservation box is recorded. The system provides a sample registration function. When the user clicks on a cryopreservation box in the list of cryopreservation boxes used, the system will give a graphical display page. Clicking on a location can quickly register the sample in the cryopreservation box.

[0077] The system supports barcode management of cryopreservation boxes. You can attach barcodes to cryopreservation boxes and quickly select cryopreservation boxes by scanning the barcodes with the barcode scanner on the refrigerator. This greatly simplifies work efficiency and makes the use of cryopreservation boxes more convenient and efficient.

[0078] Reference Figure 7 and Figure 8 The samples stored in the refrigerator are important assets of each research group. There are many laboratory personnel, and it is a problem that must be considered to ensure that the samples are not damaged or taken by mistake. For refrigerators with locks, during production, a security access module is installed in the system to implement security measures for identity recognition. Old refrigerators do not have locks, and the system has developed an electronic lock that can realize card swiping operation, thereby realizing identity recognition.

[0079] First, each research group can only open its own refrigerator to prevent samples from being taken away and lost by members outside the research group. Within the research group, the refrigerator can only be unlocked if there are samples of the user. After unlocking, the location of the user's cryopreservation box will be marked on the screen to prevent the problem of taking the wrong one.

[0080] Reference Fig. 9 A barcode with information about the associated researcher is set on the freezing box, and a barcode scanner is set on the refrigerator; when the freezing box application information is received, the barcode scanner on the refrigerator scans the barcodes on the freezing boxes in turn, selects the freezing boxes associated with the freezing box application information, and displays the corresponding positions through the touch screen.

[0081] Since a large number of frozen boxes and samples are stored in the refrigerator, if the refrigerator fails, the samples will become invalid, which is an immeasurable loss for the laboratory. There are many reasons for refrigerator failure, and there are three common situations. One is that the load is heavy and the voltage is unstable in summer. The second is the short circuit and the circuit breaker trips. The third is the failure of the refrigerator equipment. The problem that causes the failure cannot be completely avoided. The refrigerator has an on-site alarm function. If the experimenter is not in the refrigerator room, it is difficult to find the problem. The new refrigerator will provide an alarm function, but the refrigerator needs to be connected to the external network. For data security, scientific research institutions cannot connect the equipment to the external network, so the laboratory usually adopts the paper inspection method. The paper inspection method is cumbersome, and personnel cannot conduct 24-hour inspections.

[0082] In addition, a local alarm forwarding device can be designed, which can receive the alarm signal of the refrigerator and send the alarm information to the designated laboratory manager or on-duty personnel through SMS, phone or other wireless communication methods (such as internal communication system). In this way, even if the refrigerator cannot be connected to the external network, the remote transmission of alarm information can be realized.

[0083] In this application, all refrigerators in the institute can also be connected to the server of the intranet. If the refrigerator has an interface and supports docking, the refrigerator voltage, current, door open and close status, and temperature inside the box will be transmitted to the platform in real time. For refrigerators without interfaces, an external collection terminal will be provided to collect the temperature inside the refrigerator. By setting a threshold, when it exceeds the range, the server will send a text message alarm to the refrigerator manager.

[0084] Among them, the working parameters include voltage parameters, current parameters, door opening and closing status, compressor status, and temperature inside the box.

[0085] Among them, abnormal working parameters include:

[0086] The fluctuation value of the voltage parameter is greater than the corresponding set threshold; the voltage fluctuation value is mainly calculated by analyzing the voltage waveform data, that is, the difference between the maximum and minimum values ​​of the voltage within a period of time. At the same time, it is also necessary to pay attention to the rate of voltage change, that is, the degree of rapid voltage change. According to the degree and rate of voltage fluctuation, it can be judged whether the voltage is stable and whether it exceeds the set threshold.

[0087] Or, the current parameter suddenly changes to zero, such as when a power outage or other fault occurs.

[0088] Or, the refrigerator door is open when the frozen boxes are not being taken out; if an abnormal opening is found, an alarm will be issued immediately. The manager should quickly check and close the refrigerator door to prevent temperature fluctuations and damage to the samples.

[0089] Or, the operating noise of the compressor is greater than the corresponding set threshold; the system should issue an alarm to prompt the management staff to check whether the compressor is loose, whether the lubrication is sufficient, or whether parts need to be replaced.

[0090] Or, the temperature inside the box exceeds the corresponding set threshold. When the temperature inside the box rises abnormally, the system should immediately issue an alarm and initiate emergency cooling measures (if available). At the same time, the manager should check whether the refrigerator refrigeration system is working properly, adjust the temperature setting or take other measures to ensure the safety of the samples.

[0091] Compared with other similar products in the embodiments of the present application, the characteristics of the present technical solution are manifested in three aspects:

[0092] First, this application belongs to a platform product, which is suitable for unified management of refrigerators in all laboratories within the institute.

[0093] Second, the system focuses on the space usage and utilization rate of the refrigerator, and pays attention to the management of cryoboxes rather than the management of samples. This not only frees users and teachers, that is, researchers, from complicated work, but also meets the business needs of project team managers to understand the utilization rate of each refrigerator at a glance.

[0094] Third, with the help of smart hardware and Internet of Things technology, authorized access and storage security management of refrigerators are achieved without increasing the burden on users.

[0095] In other embodiments, there is also the following alternative method 1 for the safe access method of the cryopreservation box:

[0096] The cryobox is equipped with passive NFC, which is used to store and transmit the unique identification information of the cryobox. The refrigerator is equipped with a cabinet gun (or barcode scanner) for scanning barcodes, and a touch screen for display and indication. The researchers use a bracelet with NFC and a display screen to pick up and put down the cryobox, which is used for NFC connection with the cabinet gun and transmission of barcode information. A prompt light is set at each cryobox to provide visual instructions during the picking and placing process. The system background terminal is responsible for processing registration information, sending identity barcode information and NFC information, and performing information comparison and verification.

[0097] Pick and place methods include:

[0098] S1, first, register the wristband to the background terminal as a researcher.

[0099] S2, after successful registration, the background terminal sends the identity barcode information associated with the registration information to the bracelet, and sends NFC information to the cabinet gun.

[0100] S3, the identity barcode information on the bracelet is paired with the cabinet gun through NFC connection.

[0101] S4, after successful pairing, the cabinet gun compares the identity barcode information with the NFC information sent to the cabinet gun by the background terminal to ensure the validity of the researcher's identity.

[0102] S5, if the wristband is successfully matched, the wristband sends the barcode information corresponding to the access cryogenic box A to the cabinet gun.

[0103] S6, the cabinet gun scans the freezing box in the refrigerator. When the barcode information sent by the bracelet to the cabinet gun matches the passive NFC on the freezing box A, the area corresponding to the freezing box A on the display touch screen is marked; or, the prompt light corresponding to the freezing box A is on.

[0104] S7, after taking away the cryobox A indicated by the prompt, the barcode information on the wristband is scanned again by the passive NFC on the cabinet gun; if the scan matches successfully, it is determined that the cryobox A taken and placed is correct; if the scan matches fail, the wristband vibrates to remind the researcher of the operation error.

[0105] S8, if the number of the cryoboxes to be taken in and out is greater than or equal to two, after taking in and out cryobox A, the process returns to step S5, and the wristband sends the barcode information corresponding to the access cryobox B to the cabinet gun.

[0106] The above method first authenticates the user through the bracelet to ensure the user's identity is correct. Then, the bracelet is paired with the cabinet gun on the refrigerator for the first time using Bluetooth pairing technology to facilitate the transmission of information. Then, the relevant information of the frozen box that the bracelet user needs to access is sent to the cabinet gun, so that the cabinet gun can quickly prompt the location information of the frozen box; in order to avoid taking the wrong box, especially when multiple users take it at the same time, when the user takes out the frozen box, due to the wearing of the bracelet, the NFC technology can be used to re-check whether the taken out frozen box and the bracelet are correct. If correct, there is no vibration; if there is an error, a vibration reminder will be sent.

[0107] In other embodiments, there is also the following alternative method 2 for accessing the cryopreservation box:

[0108] The cryobox is equipped with passive NFC, and the refrigerator is equipped with a cabinet gun for scanning barcodes. The researchers use a wristband with NFC and a display to take and put the cryobox; the taking and putting methods include:

[0109] s1, register the bracelet to the background terminal as a researcher.

[0110] s2. After successful registration, the background terminal sends the identity barcode information associated with the registration information to the bracelet, and sends NFC information to the cabinet gun.

[0111] s3, the identity barcode information on the bracelet is paired with the cabinet gun through NFC connection.

[0112] s4. After pairing is successful, the cabinet gun compares the identity barcode information with the NFC information sent to the cabinet gun by the background terminal.

[0113] s5. If the wristband is successfully matched, the wristband displays the barcode information corresponding to the cryo box a to be taken out.

[0114] s6, after the wristband is scanned by the cabinet snatcher, the cabinet snatcher sends the NFC information corresponding to the frozen storage box a information corresponding to the taking and placing to the wristband.

[0115] s7, the wristband scans the cryopreservation boxes in turn. When the wristband matches the cryopreservation box a successfully, the wristband vibrates to remind the researchers of the operation error.

[0116] s8, if the number of the cryopreservation boxes to be taken out is greater than or equal to two, after taking out the cryopreservation box a, return to step s5, and the wristband displays the barcode information corresponding to the cryopreservation box b to be taken out.

[0117] The above method first authenticates the identity through the wristband to ensure the correct identity of the user. Then, using Bluetooth pairing technology, the wristband is paired with the cabinet gun on the refrigerator for the first time to facilitate the transmission of information. The information of the frozen box is then presented on the wristband in the form of a barcode. When taking the frozen box, the cabinet gun scans the code. If the code is successfully scanned, it means that the frozen box is indeed stored in the refrigerator. Then the cabinet gun sends the NFC information corresponding to the frozen box a information corresponding to the taking and placing to the wristband. The user moves the wristband to pair the frozen box in the refrigerator using NFC radio frequency. If the pairing is successful, the wristband vibrates, indicating that the frozen box is matched correctly. Otherwise, it does not vibrate and continues to move the wristband to search.

[0118] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
