Description

TECHNICAL FIELD

[0001] The present application relates to the sorting of single-piece articles in high-end equipment manufacturing, mechanical hands / container equipped with manipulation devices, storage devices, artificial intelligence systems in the production field, image recognition and understanding in the field of new generation information technology, and in particular to an intelligent storage device for plug-in electronic keys. BACKGROUND

[0002] Currently, UKEY (full name "USB KEY", an electronic key device based on a USB interface) is widely used in many fields as a common identity authentication and data encryption tool. For example, when conducting business, UKEY devices need to be used for login and identity verification. The staff needs to find the corresponding UKEY device for the business under the company entity in advance and connect it. After use, it needs to be disconnected and returned. When conducting business on site, the staff needs to carry the UKEY.

[0003] For an HR SaaS service enterprise that provides comprehensive shared service solutions for enterprise entities, the UKEYs it manages are often thousands, and the types include bank UKEYs, social security UKEYs, tax UKEYs, etc. The existing technology is to manually insert each UKEY into the corresponding socket, and then record the UKEY number and its socket in the database. When the UKEY needs to be replaced or taken down for on-site business, the UKEY needs to be removed. At this time, it is more cumbersome to query the UKEY socket position and remove the UKEY, which needs to be checked one by one to ensure that it cannot be pulled out incorrectly. Because if the important UKEY being run is pulled out incorrectly, it may cause immeasurable trouble and loss. And after the business is completed, the UKEY is inserted back into the corresponding socket. These processes need a large number of personnel to participate, and the error probability is very high.

[0004] Although the existing technology has an electronic UKEY management method, when the UKEY position is inserted incorrectly, the system and the socket cannot correctly identify the identity of the UKEY, which will cause the electronic management means to fail, and the management personnel cannot find the UKEY, and the manual search is time-consuming and laborious, thereby causing great difficulty in business handling and causing customer complaints.

[0005] In summary, in the scenario of using a large number of UKEYs, the existing technology needs manual insertion and maintenance, which is not only inefficient but also prone to errors in scenarios where UKEYs need to be frequently replaced. And due to the particularity of UKEYs, the existing electronic management means will fail in some situations. SUMMARY

[0040] III. Beneficial Effects

[0041] From the above technical solutions, the present application has at least one of the following beneficial effects compared with the prior art:

[0042] 1. The present application realizes accurate identification of both the electronic key and the key interface through the visual recognition large model, and realizes the automatic management of the electronic key by combining the management logic setting of the mechanical plug-in unit and the control unit, which saves a large amount of human resources on the one hand, and improves the accuracy of management on the other hand, avoids the occurrence of poor management conditions such as loss and misplug of the electronic key, and reduces the operating risk of the HR SaaS service enterprise.

[0043] 2. In the present application, the front and back of the UKEY are both pasted with a two-dimensional code indicating its own identity, and the front of the UKEY is also provided with text information indicating its own identity. Compared with text, the two-dimensional code is more conducive to identification and has higher identification accuracy. The setting of text information on the UKEY can facilitate the user to identify the UKEY when taking it down to handle business, and the convenience is better.

[0044] 3. To ensure the optical camera can successfully capture information from the U-Key, the vertical and horizontal spacing between adjacent key slots should be greater than 3cm, and the brightness at the key slot locations within the cabinet should be no less than 150 lumens per square meter. The advantage of this setup is that the optical camera can capture the U-Key's QR code more closely and clearly, improving recognition accuracy.

[0045] 4. In this invention, the UKEY transfer station is a physical UKEY transfer compartment located below the UKEY cabinet; the UKEY temporary storage station is a UKEY temporary storage compartment located below the UKEY cabinet and arranged side by side with the UKEY transfer station. To facilitate retrieval by the mechanical plug-in unit, both extend forward on the front of the cabinet. The advantage of this arrangement is that multiple UKEYs can be accommodated in both the transfer station and the temporary storage station. When a UKEY needs to be archived, the user simply places the UKEY in the transfer station, which is simple and convenient.

[0046] 5. In this invention, the transmission mechanism includes a multi-degree-of-freedom (DOF) robotic arm, which is mounted on a transverse guide rail and can move left and right via a transverse traveling device. A gripping device for grasping a U-key is located at its distal end. A control unit controls the movement of the multi-DOF robotic arm. A camera is positioned at the distal end of the multi-DOF robotic arm to facilitate capturing clearer images of the U-key's QR code label. Simultaneously, information such as the U-key's connector captured by the camera is uploaded to the control unit for controlling the multi-DOF robotic arm.

[0047] 6. Due to insufficient lighting inside the cabinet and the fact that the optical camera and the QR code cannot be directly aligned, the large-scale visual recognition model needs to be trained using QR code training data under different lighting conditions, shooting angles, and attachment surfaces.

[0048] Compared to traditional OCR technology, the large visual recognition model of this invention can adapt to the recognition of new UKEY models and has better generalization ability. According to the needs of different users, the large visual recognition model of this invention can be retrained to adapt to specific usage scenarios, and continuously learns and optimizes itself to improve performance.

[0049] 7. In this invention, the control unit internally stores a key management database. This key management database stores the identity information and specific location of all U-keys in the cabinet. The device identity of the electronic key includes: type, customer company identity, and priority. The type is one of the following: bank U-key, tax U-key, or business registration U-key; the customer company identity is one of the following: customer company name or customer company code; and the priority is the priority level of the electronic key's use of the key slot. The type, company name, and priority are stored in the key management database after being obtained via a QR code. Through the key management database, this invention can conveniently perform operations such as U-key archiving, lending, searching, priority access, and fault handling.

[0050] 8. This invention manages hundreds of USB keys within a cabinet through identification devices, mechanical plug-in / plug-out units, and control units, automating most daily USB key maintenance tasks. Daily manual work only requires adding and removing USB keys; other maintenance is only necessary in case of malfunction. Through these technical means, this invention significantly improves the operating efficiency of the USB key storage device and reduces human resource costs. Attached Figure Description

[0059] The inventive concept of this invention lies in achieving accurate identification of both electronic keys and key interfaces through a large visual recognition model. Combined with the management logic settings of the mechanical plug-in unit and control unit, it realizes automated management of electronic keys. On the one hand, it saves a lot of human resources, and on the other hand, it improves the accuracy of management, avoids the occurrence of poor management such as lost or misinserted electronic keys, and reduces the operational risks of HR SaaS service companies.

[0060] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0061] This invention provides a pluggable intelligent electronic key storage device. Figure 1 This is a schematic diagram of the pluggable electronic key intelligent storage device of the present invention. Figure 2 for Figure 1 The diagram shows the control logic of a pluggable electronic key intelligent storage device. Figure 1 and Figure 2 As shown, in this embodiment, the UKEY intelligent storage device includes:

[0062] Cabinet 10, which has N fixed expansion docks 11 inside, and each expansion dock is equipped with one or more UKEY ports 12, where N≥1;

[0063] The U-Key transfer station is located on the front of the U-Key port in the U-Key cabinet;

[0064] The UKEY temporary storage area is located on the front of the UKEY port in the UKEY cabinet;

[0065] The identification acquisition unit is used to acquire the identification of the UKEY;

[0066] Mechanical plug-in unit 40 is located on one side of the front of the UKEY port in the UKEY cabinet;

[0067] Control unit 50, whose signals are connected to the identification acquisition unit and the mechanical plug-in unit, executes the following control logic:

[0068] Receive the identifier of the UKEY uploaded by the identifier collection unit;

[0069] The device identity of the UKEY is determined by its identifier;

[0070] Control the mechanical insertion / removal unit to remove the UKEY from the UKEY transfer position and insert it into the corresponding UKEY socket; or, remove the UKEY from the corresponding UKEY socket and transfer it to the UKEY transfer position.

[0071] The following is a detailed description of each part of the pluggable electronic key intelligent storage device in this embodiment.

[0072] In this embodiment, a U-key is used as an example for illustration, but the present invention is not limited thereto. In other embodiments of the present invention, other forms of pluggable electronic keys can also be applied to the present invention and are also within the scope of protection of the present invention. Here, electronic key refers to an electronic device associated with user identity.

[0073] In this embodiment, seven expansion docks 11 are arranged vertically inside the cabinet 10. Each expansion dock has three rows of UKEY ports 12, with each row containing ten UKEY ports.

[0074] Those skilled in the art should understand that the number and arrangement of the expansion docks in the cabinet, and the number and arrangement of the UKEY ports on the expansion docks, can all be set according to the size and space of the cabinet. As long as the identification acquisition unit can acquire the identification of the corresponding UKEY and the mechanical plug-in unit can perform plug-in and plug-out operations on the corresponding UKEY, it is within the protection scope of this invention.

[0075] In this embodiment, QR codes identifying the user are affixed to both the front and back of the UKEY, and text information identifying the user is also provided on the front of the UKEY. Compared to text, QR codes are easier to recognize and have a higher recognition accuracy. Furthermore, by setting text information on the UKEY, users can easily identify the UKEY when it is removed for business transactions, thus improving convenience.

[0076] Those skilled in the art will understand that the QR code of the UKEY can also be added to the UKEY casing or accessories by means of printing or laser engraving. Furthermore, in addition to using a QR code image as the identifier of the UKEY, text identifiers can also be used. Moreover, in some embodiments of the present invention, an NFC identifier can also be used, with the identifier acquisition unit using an NFC reading device. These variations can also achieve the present invention and are also within the protection scope of the present invention.

[0077] In this embodiment, the identification acquisition unit, corresponding to image-based identifiers such as QR codes and text information, is an optical camera 30. This optical camera is positioned at the far end of the mechanical plug-in unit. Driven by the mechanical plug-in unit, the optical camera's field of view covers the UKEY transfer position and each UKEY slot. To ensure the optical camera can successfully acquire information from the UKEY, the vertical and horizontal spacing between adjacent key slots is greater than 3cm, and the brightness at the key slot locations within the cabinet is no less than 150 lumens per square meter. The advantage of this configuration is that the optical camera can capture the UKEY's QR code more closely and clearly, improving recognition accuracy.

[0078] In other embodiments of the invention, the optical camera can also be fixedly mounted on the top of the UKEY cabinet and extend forward from the front of the cabinet. The advantage of this design is that the optical camera is less prone to damage, resulting in higher system reliability.

[0079] Those skilled in the art should understand that the above is merely a specific design based on the relevant parameters of the optical camera, and the present invention is not limited thereto. In other embodiments of the present invention, the number and spacing of the UKEY ports, as well as the lighting conditions inside the cabinet, can also be set according to the specific parameters of the optical camera, and the present invention can still be achieved, and are also within the protection scope of the present invention.

[0080] In this embodiment, the UKEY transfer station is a physical UKEY transfer compartment 21 located below the UKEY cabinet; the UKEY temporary storage compartment is a UKEY temporary storage compartment 22 located below the UKEY cabinet and arranged side by side with the UKEY transfer station. Both extend forward on the front of the cabinet to facilitate retrieval by the mechanical plug-in unit. The advantage of this arrangement is that multiple UKEYs can be accommodated in both the transfer station and the temporary storage compartment. When a UKEY needs to be archived, the user simply places it in the transfer station, which is simple and convenient.

[0081] In this embodiment, the UKEY temporary storage compartment 22 is used to temporarily accommodate the UKEY when there are insufficient UKEY slots. If there is sufficient redundancy in the UKEY slots, the UKEY temporary storage compartment 22 may not be set up.

[0082] In other embodiments of the present invention, the transfer slot and temporary storage slot of the UKEY can also be blank UKEY slots. The advantage of this arrangement is that it can make full use of the rack space, the mechanical plug-in unit no longer needs to reach into the compartment to retrieve and place the UKEY, and its design is simpler and more flexible.

[0083] In this embodiment, the mechanical insertion and removal unit 40 includes: a guide mechanism; a transmission mechanism disposed on the guide mechanism; and a clamping device disposed at the distal end of the transmission mechanism; wherein, the guide mechanism transfers the transmission mechanism to a preset height; the transmission mechanism drives the clamping device to move back and forth; the clamping device performs the clamping or releasing action of the electronic key; and the drive system is responsible for providing power to the guide mechanism, the transmission mechanism, etc.

[0084] The guiding mechanism ensures the accurate positioning of the clamping mechanism during insertion and removal. The guiding mechanism can employ linear guides, guide posts, or guide sleeves. Linear guides offer advantages such as high precision and a low coefficient of friction, ensuring smooth movement of the clamping mechanism. Guide posts and guide sleeves, on the other hand, have a simpler structure and lower cost, making them suitable for applications where high precision is not required.

[0085] Please refer to Figure 1 In this embodiment, the guiding mechanism includes: longitudinal guide rails, including a left longitudinal guide rail and a right longitudinal guide rail, which are respectively disposed on the left and right sides of the UKEY cabinet frame; a crossbeam, which is vertically movable between the left and right longitudinal guide rails via a longitudinal traveling device 41; a transverse guide rail, which is disposed on the crossbeam and has a transverse traveling device disposed thereon; and a transmission mechanism, which is horizontally movable on the transverse guide rail via a transverse traveling device 42, with a clamping device for clamping the UKEY at its distal end; wherein, the control unit controls the longitudinal traveling device, the transverse traveling device, and the transmission mechanism, and the movement range of the clamping device is: up and down to the top and bottom UKEY interfaces in the UKEY cabinet respectively, and in the depth direction to the insertion position of the deepest UKEY interface in the UKEY cabinet.

[0086] The transmission mechanism is used to push the gripping device to insert / remove the UKEY into the UKEY slot after reaching the preset position. Furthermore, when the UKEY transfer position is a transfer compartment, the transmission mechanism can also be used to pick up the UKEY from within the transfer compartment.

[0087] Please refer to Figure 1 In this embodiment, the transmission mechanism includes a multi-degree-of-freedom (DOF) robotic arm 43, which is mounted on a transverse guide rail and can move left and right via a transverse traveling device. Its distal end is equipped with a gripping device for grasping the UKEY. A control unit controls the movement of the multi-degree-of-freedom robotic arm. A camera is positioned at the distal end of the multi-degree-of-freedom robotic arm to facilitate capturing clearer images of the UKEY's QR code label. Simultaneously, information such as the UKEY's connector captured by the camera is uploaded to the control unit for controlling the multi-degree-of-freedom robotic arm.

[0088] In this embodiment, the multi-degree-of-freedom robotic arm can precisely control the gripping and releasing of the U-key. For example, an electric gripper can be used, which has advantages such as adjustable force and stable gripping. When gripping the U-key, it is necessary to ensure that the U-key is not damaged, while firmly holding the U-key for insertion and removal operations.

[0089] In addition, to achieve automatic insertion and removal, sensors need to be installed in the clamping device to detect the position and status of the U-key. For example, an image sensor can be installed to detect whether the U-key is inserted correctly, and a pressure sensor can be installed to detect whether the clamping force of the clamping mechanism is appropriate. These sensors can feed back the detected signals to the control unit so that the clamping force can be adjusted accordingly.

[0090] The drive system can use actuators such as motors and cylinders. Motors have advantages such as high control precision and a wide speed range, making them suitable for applications requiring high motion accuracy. Cylinders, on the other hand, feature rapid action and high output force, meeting the needs of quick insertion and removal.

[0091] In the second embodiment of the present invention, the multi-degree-of-freedom manipulator can also be replaced by other means, for example: the transmission mechanism includes: a controlled rotating disk, the extension plane of which is perpendicular to the transverse guide rail; a telescopic transmission rod, fixed to the controlled rotating disk, the distal end of which is provided with a gripping device for gripping the UKEY, wherein the control unit is used for:

[0092] ① Control the rotation of the controlled rotating disk so that the transmission rod is aligned with the UKEY interface or the UKEY rotation position;

[0093] ② Control the extension and retraction of the telescopic transmission rod to make the gripping device move forward or backward toward the UKEY interface or the UKEY rotation position.

[0094] The telescopic transmission rod can be driven by a lead screw and nut, or by a rack and pinion mechanism. Lead screw and nut drives offer advantages such as high precision and smooth transmission, making them suitable for applications requiring high positional accuracy. Rack and pinion drives, on the other hand, feature high transmission speed and strong load-bearing capacity, meeting the needs for rapid movement.

[0095] In the third embodiment of the present invention, other types of guiding mechanisms and transmission mechanisms may also be used. Specifically, in the mechanical insertion and removal unit of the third embodiment, the guiding mechanism includes: a longitudinal guide rail, disposed on the left or right side of the UKEY cabinet frame; a mounting platform, which is fixed to the longitudinal guide rail and can be moved up and down via a longitudinal traveling device; the transmission mechanism includes: a multi-degree-of-freedom manipulator, fixed to the mounting platform, with a gripping device for gripping the UKEY at its distal end; wherein, the control unit controls the longitudinal traveling device and the multi-degree-of-freedom manipulator, and the movement range of the gripping device is: up and down to the top and bottom UKEY interfaces in the UKEY cabinet respectively, and in the depth direction to the insertion position of the deepest UKEY interface in the UKEY cabinet.

[0096] Please refer to Figure 2 In this embodiment, the control unit is the core component. It is responsible for receiving signals from the sensors and controlling the mechanical plug-in unit to perform corresponding actions based on these signals. The control unit can be implemented using a microcontroller, PLC, or other controllers. Microcontrollers have advantages such as small size, low cost, and strong programmability, making them suitable for some miniaturized applications. PLCs, on the other hand, have characteristics such as high reliability and strong anti-interference capabilities, making them suitable for some industrial control applications.

[0097] In this embodiment, the control unit internally stores a trained visual recognition model. This model, after training, can accurately identify the QR code ID graphic area pasted on the UKEY's outer shell surface. Combined with a QR code recognition algorithm, it accurately obtains the UKEY ID, thereby precisely identifying the individual UKEY and transmitting the data to the UKEY management information system for recording and management. Furthermore, the visual recognition model can also identify the UKEY port number and accurately determine the relative position of the port to the multi-degree-of-freedom robotic arm. This position is transmitted to the control unit, participating in the robotic arm's movement position control and posture control. It further participates in the control loop for the robotic arm's movement and alignment with the cabinet ports.

[0098] In this embodiment, the large-scale visual recognition model can be a GLM model with a parameter scale of 7B or 13B. This large-scale visual recognition model is trained using a large number of visual images of UKEY QR codes and UKEY shapes to achieve the ability to accurately identify the type and model of UKEY through visual images.

[0099] It should be noted that due to insufficient lighting inside the cabinet and the fact that the optical camera and the QR code cannot be directly aligned, the large visual recognition model needs to be trained using QR code training data under different lighting conditions, different shooting angles, and different attached surfaces.

[0100] Compared to traditional OCR technology, the large visual recognition model in this embodiment can adapt to the recognition of new UKEY models and has better generalization ability. According to the needs of different users, the large visual recognition model in this embodiment can be retrained to adapt to specific usage scenarios, and continuously learns and optimizes itself to improve performance.

[0101] In this embodiment, the control unit internally stores a key management database. This database stores the identity information and specific location of all U-keys in the cabinet. The device identity of the electronic key includes: type, customer company identity, and priority. The type is one of the following: bank U-key, tax U-key, or business registration U-key; the customer company identity is one of the following: customer company name or customer company code; and the priority is the priority level of the electronic key's use of the key slot. The type, company name, and priority are stored in the key management database after being obtained via QR code.

[0102] With the help of the key management database, the pluggable electronic key intelligent storage device in this embodiment can easily perform operations such as UKEY archiving, lending, searching, queue insertion, and fault handling.

[0103] Users can add or remove UKEYs from the device. Once a user initiates a command, the device responds to the customer's request and begins the response process. Users can also initiate UKEY connection and removal, change the port location, or retrieve the UKEY's port location via the control unit. The identification acquisition unit and mechanical insertion / removal unit will respond to the control unit's commands and execute the corresponding operations.

[0144] The following section, in conjunction with the hardware structure and overall process described above, will explain in detail how the pluggable electronic key intelligent storage device in this embodiment achieves various types of functions.

[0145] 1. Key search logic

[0146] The control unit executes the key search logic in the following scenarios: ① No UKEY to be searched exists in the key management database; ② The key slot corresponding to the recorded UKEY to be searched is empty; ③ The key slot corresponding to the recorded UKEY to be searched is not occupied by the UKEY to be searched.

[0147] Figure 4 for Figure 1 The flowchart shown illustrates the key search logic implemented by the control unit in the pluggable electronic key intelligent storage device. Please refer to... Figure 2 and Figure 4 In this embodiment, the control unit executes the key search logic, including:

[0148] Step S102: Receive the identity of the device whose UKEY is to be found;

[0149] Step S104: The identification acquisition unit traverses each key slot, UKEY temporary storage bit, and UKEY transfer bit in the cabinet, and determines the identity of the UKEY through the QR code identification of the UKEY until the UKEY to be found is found.

[0150] In real-world scenarios, after locating the UKEY, it can be inserted into the desired UKEY slot or placed in the UKEY transfer compartment for user use, depending on the user's needs.

[0151] Those skilled in the art will understand that this key search logic is particularly suitable for situations where the UKEY is inserted into the wrong UKEY slot, causing the device identity of the UKEY to be incorrectly recorded in the key management database, which can greatly reduce the burden of manual searching. Furthermore, by having the control unit periodically archive and organize the UKEYs in the pluggable electronic key intelligent storage device, the probability of UKEY loss can be greatly reduced.

[0152] 2. Key archiving logic

[0153] The scenario in which the control unit executes the key search logic is as follows: when a user returns the UKEY, the system needs to return the UKEY to the correct location and record it in the key management database.

[0154] Figure 5 for Figure 1 The flowchart shown illustrates the key archiving logic implemented by the control unit in the pluggable electronic key intelligent storage device. Please refer to... Figure 2 and Figure 5 In this embodiment, the identification acquisition unit first detects a new UKEY in the UKEY transfer compartment, captures the identification of the UKEY, and then uploads it to the control unit. The control unit executes the key archiving logic, including:

[0155] Step S202: Receive the identifier of the UKEY in the key transfer position uploaded by the identifier acquisition unit;

[0156] Step S204: Determine the device identity of the UKEY through its identifier;

[0157] Step S206: Through the key management database, the corresponding key slot is planned according to the device identity of the UKEY. If there is an empty UKEY slot, proceed to step S208.

[0158] Step S208: The mechanical insertion and removal unit is instructed to remove the UKEY from the key and insert it into the corresponding key slot;

[0159] Step S216: Update the management status information of UKEY in the key management database.

[0160] As can be seen, with the key archiving logic of this embodiment, maintenance personnel only need to put the new UKEY provided by the customer company into the UKEY compartment entrance in the cabinet. There are no restrictions on the posture and position of the placement. The control unit can automatically move and identify the UKEY location, model, and tag ID, and automatically plan the interface position. The multi-degree-of-freedom robotic arm picks up the UKEY from the compartment and moves it to the corresponding free port for insertion, which greatly facilitates personnel operation.

[0161] 3. Key insertion logic

[0162] The key management database stores the priorities of electronic keys. When the number of UKEY server interfaces is limited, and the number of available interfaces is less than the number of UKEYs maintained, some low-priority UKEYs that are not currently in use can be allocated to free up interfaces for urgent UKEY processing. This key queueing logic increases the number of UKEYs that can be processed, overcoming limitations imposed by the number of hardware interfaces and improving system efficiency.

[0163] Please refer to Figure 2 and Figure 5 In this embodiment, in step S206, if all key slots in the rack are occupied, the key queueing logic is executed, including:

[0164] Step S210: Query the key management database and select the second UKEY that occupies the key slot, is not currently in operation, and has a lower priority than the UKEY;

[0165] Step S212: The mechanical insertion and removal unit is instructed to remove the second UKEY from the corresponding second key socket and transfer it to the key temporary storage position.

[0166] Step S214: The mechanical insertion and removal unit removes the UKEY from the key transfer position and inserts it into the second key socket, and then executes step S216.

[0167] 4. Key lending logic

[0168] When a customer needs to retrieve their USB key for various reasons, such as needing to take it to a company office, a branch office, for periodic updates, or upon termination of cooperation, a multi-degree-of-freedom robotic arm automatically moves to the corresponding interface, removes the USB key, and moves it to the normal exit position of the USB key storage compartment for maintenance personnel to retrieve.

[0169] Figure 6 for Figure 1 The flowchart shown illustrates the key lending logic implemented by the control unit in the pluggable electronic key intelligent storage device. Please refer to... Figure 2 and Figure 6 The control unit executes the key lending logic, including:

[0170] Step S302: Receive the device identity of the UKEY to be lent out;

[0171] Step S304: Query the key management database to determine the key slot where the UKEY to be lent is located;

[0172] Step S306: Receive the identifier of the current UKEY inserted into the key slot uploaded by the identifier acquisition unit;

[0173] Step S308: Determine the device identity of the current UKEY by the identifier of the current UKEY;

[0174] Step S310: Determine whether the device identity of the UKEY to be lent out is consistent with the device identity of the current UKEY. If yes, proceed to step S312; otherwise, proceed to step S316.

[0175] Step S312: The mechanical insertion and removal unit removes the UKEY from the key slot and transfers it to the key transfer position;

[0176] Step S314: Update the management status information of UKEY in the key management database, and the process ends;

[0177] Step S316: Execute the error reporting procedure, re-determine the port for the UKEY to be lent out, and the process ends.

[0178] 5. Key Failure Handling Logic

[0179] When a communication failure is detected in a USB key during operation, a multi-degree-of-freedom robotic arm automatically moves to the corresponding location and attempts to re-insert and re-plug the USB key to repair the fault. If the fault cannot be resolved in the original location, the arm can be further tested by changing the insertion port position and re-inserting the USB key. If the fault still cannot be resolved, an alarm will be triggered and the faulty USB key will be moved to the fault exit of the USB key transfer compartment for maintenance personnel to retrieve and repair.

[0180] Figure 7 for Figure 1The flowchart shown illustrates the key fault handling logic implemented by the control unit in the pluggable electronic key intelligent storage device. Please refer to... Figure 2 and Figure 7 The control unit executes key failure handling logic, including:

[0181] Step S402: Receive device identity information of the suspected faulty UKEY;

[0182] Step S404: Query the key management database to determine the key slot where the suspected faulty UKEY is located;

[0183] Step S406: Receive the identifier of the current UKEY of the key slot uploaded by the identifier acquisition unit;

[0184] Step S408: Determine the device identity of the current UKEY by using the identifier of the current UKEY;

[0185] Step S410: Determine whether the device identity of the suspected faulty UKEY matches the device identity of the current UKEY. If yes, proceed to step S412; otherwise, proceed to step S420.

[0186] Step S412: The mechanical insertion and removal unit removes the UKEY from the key socket and inserts it into the third key socket.

[0187] Step S414: If the UKEY still does not work properly in the third key slot, proceed to step S416; otherwise, proceed to step 422.

[0188] Step S416: The mechanical insertion and removal unit is instructed to remove the UKEY from the third key socket and transfer it to the key transfer position;

[0189] Step S418: Update the management status information of UKEY in the key management database, and the process ends;

[0190] Step S420: Execute the error reporting procedure to re-identify the port of the suspected faulty UKEY, and the process ends;

[0191] Step S422: Report that the UKEY is working normally, but the key slot is suspected to be faulty. The process ends.

[0192] 6. Key socket redistribution logic

[0193] In system maintenance scenarios, the allocation of UKEY interfaces can be replanned, and a multi-degree-of-freedom robotic arm can move the UKEYs in batches to the interface positions to perform plug-in and unplug operations.

[0194] Figure 8 for Figure 1 The flowchart shown illustrates the key slot redistribution logic implemented by the control unit in the pluggable electronic key intelligent storage device. Please refer to...Figure 2 and Figure 8 The control unit executes the key socket reallocation logic, including:

[0195] Step S502: Receive the key socket redistribution scheme;

[0196] Step S504, for each key entry in the key interposer redistribution scheme:

[0197] Sub-step S504a: Instruct the identification acquisition unit to acquire the identification of the target key slot in the key slot redistribution scheme for the UKEY to be allocated.

[0198] Sub-step S504b: Determine whether the target key slot is empty based on the identifier of the target key slot. If it is not empty, execute sub-step S504c; otherwise, execute sub-step S504d.

[0199] Sub-step S504c: The mechanical insertion and removal unit removes the UKEY from the target key socket and transfers it to the key transfer position;

[0200] Sub-step S504d: Instruct the mechanical insertion and removal unit to remove the UKEY to be assigned from the current key slot and insert it into the target key slot.

[0201] Sub-step S504e: Update the management status information of the UKEYs to be assigned in the key management database.

[0202] The above lists six typical logics that the control unit in the pluggable electronic key intelligent storage device of this embodiment can implement. It can be seen that this embodiment manages hundreds of UKEYs in the cabinet through identification devices, mechanical pluggable units, and control units, automatically completing most daily UKEY maintenance tasks.

This embodiment, through the above-mentioned technical means, greatly improves the operating efficiency of the UKEY storage device and reduces human resource costs.
