In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0029] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through other components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0030] Based on the existing storage devices pointed out in the background technology, there is a risk of sample damage when biological samples are taken out of the warehouse and there is a problem of increasing the humidity in the storage device. The sample entry and exit control method for the storage device of the present invention, after executing the door opening operation, first determines whether the cryopreservation box has been taken away within the first preset time after the door is opened. If it has not been taken away, the cryopreservation box is transferred to the temporary storage position of the buffer area, and the door is closed to close the entrance and exit. Then it is determined whether a warehouse exit instruction is received within the second preset time. According to the judgment result, it is determined whether the cryopreservation box is taken out of the warehouse again or transferred to the freezing area for temporary storage. On the one hand, the sample can be damaged due to long-term exposure to the external environment. On the other hand, it can avoid the increase of humidity in the storage device caused by the long-term opening of the entrance and exit, which affects the temperature and humidity environment of the buffer area. On the third hand, if the sample has not performed the warehouse exit operation in the buffer area for a long time, it is transferred to the freezing area for temporary storage, which can effectively ensure the safety of the sample and prevent the inactivation of the sample.
[0031] Specifically, the storage device in the present invention includes a box body, which is divided into a buffer area and a frozen storage area. The buffer area is connected to the external environment through an entrance and exit, and the entrance and exit are opened and closed by an automatic door control. The storage temperature of the frozen storage area is lower than the storage temperature of the buffer area. Generally, the storage temperature of the buffer area is -10°C to -30°C.
[0032] The buffer area is equipped with tube picking equipment, in-and-out transfer equipment, code scanning equipment, and temporary storage racks for freezing boxes. The in-and-out transfer equipment is used to transfer freezing boxes, thereby driving the movement of samples. The tube picking equipment is used to transfer sample tubes to new freezing boxes. The code scanning equipment is used to scan the information codes of freezing boxes and samples to verify sample information. The temporary storage rack for freezing boxes is used to temporarily store freezing boxes in the buffer area. The freezing area is equipped with storage racks and transfer manipulators. The storage racks are used to place freezing boxes, and the transfer manipulators are used to take freezing boxes and put them on the storage racks.
[0033] Among them, the above-mentioned tube picking equipment, in-and-out storage transfer equipment, code scanning equipment, freezing box temporary storage rack, storage rack and transfer robot can respectively adopt conventional structures in the field, and their specific structures will not be repeated here.
[0034] In addition, the storage device of the present invention further includes a controller, and the controller is configured to be able to execute the sample storage access control method for the storage device of the present invention.
[0035] Specifically, see Figure 1 The sample access control method for a storage device of the present invention comprises the following steps:
[0036] S1: When it is necessary to remove the sample from the warehouse, the freezing box containing the sample to be removed from the warehouse is transferred to the entrance and exit, and the door opening operation is performed to open the entrance and exit.
[0037] When the sample needs to be shipped out of the warehouse, the freezing box containing the sample to be shipped out is transferred to the entrance and exit, and the door is opened to open the entrance and exit so that the user or staff can take out the freezing box or the sample tube in the freezing box through the entrance and exit.
[0038] S2: Determine whether the freezing box is taken away within a first preset time after the door is opened.
[0039] In order to prevent the sample from being exposed to the air for a long time and to prevent excessive moisture from being introduced into the storage device to affect the storage environment, it is determined whether the cryopreservation box is taken away within the first preset time after the door is opened, so as to perform the next operation.
[0040] In one embodiment, an image detection device is provided on the front side of the entrance and exit, and the image detection device detects the image of the entrance and exit in real time, so as to determine whether the frozen storage box is taken away within the first preset time after the door is opened based on the detected image.
[0041] In another embodiment, an infrared detection light curtain is provided at the front side of the entrance and exit, and sensing information of the infrared detection light curtain is used to determine whether the frozen storage box is taken away within a first preset time after the door is opened.
[0042] S31: When the judgment result is "No", the first waiting-for-delivery mode is executed. The first waiting-for-delivery mode is specifically: performing a door closing operation to close the entrance and exit, transferring the frozen box to the temporary storage position of the buffer area to wait for delivery, and displaying the confirmation of the box to be taken on the operation screen of the storage device, so that the user can directly execute the one-key delivery mode after clicking.
[0043] When the judgment result is "no", it means that the cryopreservation box has not been taken away within the first preset time, and the first waiting-for-delivery mode is executed. The cryopreservation box is transferred to the temporary storage position of the buffer area, waiting for delivery, and the door closing operation is performed to close the entrance and exit, thereby preventing external moisture from entering the buffer area, keeping the storage environment in the storage device stable, and also preventing the sample from contacting the external environment to prevent the sample from being damaged.
[0044] When executing the first waiting-to-be-released mode, the operation screen of the storage device displays confirmation of the box to be taken out so that the user or staff knows that there are samples that need to be released from the warehouse.
[0045] S4: Determine whether a dispatch instruction is received within a second preset time of executing the first dispatch mode.
[0046] When in the first waiting-to-be-outgoing mode, it is further determined whether an outgoing instruction is received within the second preset time of executing the first waiting-to-be-outgoing mode, so as to outgoing samples or transfer them to the frozen storage area for storage, so as to avoid the situation where samples are inactivated due to being in the cache area for a long time, and effectively ensure the safety of samples.
[0047] Specifically, when in the first waiting-for-out mode, when the user clicks the button corresponding to the confirmation of the box to be picked up on the operation screen of the storage device, the outbound instruction is received; if the button corresponding to the confirmation of the box to be picked up is not clicked within the second preset time of the first waiting-for-out mode, the outbound instruction is not received.
[0048] S5: According to the judgment result, selectively execute the one-key outgoing mode or the second waiting outgoing mode. The one-key outgoing mode specifically includes: transferring the frozen storage box at the temporary storage position to the entrance and exit, and performing the door opening operation to open the entrance and exit so that the user can take out the frozen storage box.
[0049] The second waiting-to-be-released mode is specifically as follows: the frozen storage box located at the temporary storage position is transferred to the freezing area for temporary storage to wait for subsequent release from the warehouse, and the problem box is displayed as waiting to be released from the warehouse on the operation screen of the storage device so that the user can release the frozen storage box after clicking it.
[0050] When executing the second waiting-to-be-released mode, the operation screen of the storage device displays that there are problem boxes waiting to be released, so that the user or staff knows that there are samples that need to be released.
[0051] The sample entry and exit control method for storage equipment of the present invention first determines whether the cryobox has been taken away within the first preset time after the door is opened after executing the door opening operation. If not, the cryobox is transferred to the temporary storage position of the buffer area, the door is closed to close the entrance and exit, and then it is determined whether a warehouse exit instruction is received within the second preset time. According to the judgment result, it is determined whether the cryobox is to be taken out of the warehouse again or transferred to the cryobox for temporary storage. On the first hand, it can prevent the sample from being damaged due to being exposed to the external environment for a long time. On the second hand, it can prevent the humidity in the storage device from increasing due to the long-term opening of the entrance and exit, thereby affecting the temperature and humidity environment of the buffer area. On the third hand, if the sample has not executed the warehouse exit operation in the buffer area for a long time, it is transferred to the cryobox for temporary storage, which can effectively ensure the safety of the sample and prevent the sample from inactivation.
[0052] It should be noted that when the outbound operation in the outbound process of the one-key outbound mode is executed, the sample in and outbound control method of the present invention is also applicable, and the process returns to step S1 to continue the judgment.
[0053] Preferably, please refer to Figure 2Step S5 "selectively executing the one-key outbound mode or the second outbound mode according to the judgment result" specifically includes:
[0054] S51: Execute one-key outbound mode.
[0055] When the judgment result is "yes", that is, the outbound instruction is received within the second preset time of executing the first waiting outbound mode, it means that there is someone waiting outside the entrance and exit to receive the sample. Then the one-key outbound mode is executed, the frozen storage box at the temporary storage position is transferred to the entrance and exit, and the door opening operation is performed to open the entrance and exit so that the user can take out the frozen storage box.
[0056] S52: Execute the second waiting-for-delivery mode.
[0057] When the judgment result is "no", that is, no outbound instruction is received within the second preset time of executing the first waiting-for-outbound mode, indicating that there is no one outside the entrance and exit, the second waiting-for-outbound mode is executed, and the frozen storage box located at the temporary storage position is transferred to the freezing area for temporary storage to wait for subsequent outbound delivery. In addition, the operation screen of the storage device displays the problem box waiting for outbound delivery, so that the user can click to deliver the frozen storage box.
[0058] Preferably, please continue to see Figure 2 After executing "determining whether the freezing box is taken away within the first preset time after opening the door", the sample entry and exit control method also includes: S32: when the judgment result is "yes", the door closing operation is executed to close the entrance and exit.
[0059] After the freezing box is taken away within the first preset time, the door closing operation is performed to close the entrance and exit, and the entrance and exit are closed in time to prevent external moisture from continuing to enter the storage device.
