Technical Field
[0001] This utility model relates to the field of device access control technology, specifically a device access control management device. Background Technology
[0002] Against the backdrop of rapid development in industrial automation, intelligent manufacturing, and the Internet of Things, device access management, as a core component to ensure the safe operation of industrial systems, is becoming increasingly important. With the increasing intelligence of industrial equipment, the number of connected devices is surging and the interaction scenarios are becoming more complex, which places higher demands on the security, flexibility, and real-time performance of access management. However, traditional device access management devices have gradually revealed many limitations in practical applications.
[0003] Traditional devices often employ an integrated hardware design with highly integrated functional modules (such as permission verification, data storage, and communication interfaces), making it difficult to flexibly adjust functions according to actual needs. When industrial scenarios require the addition of new permission types (such as temporary authorization or multi-level permission subdivision) or adaptation to new equipment, the entire device must be replaced, resulting in high upgrade costs and long cycles. This fails to meet the dynamic needs of diverse scenarios. Furthermore, some devices rely on software encryption to protect permission data, lacking hardware-level protection mechanisms. In industrial environments, permission data is easily leaked due to attacks such as physical disassembly and chip reading, leading to security risks such as unauthorized operations and equipment malfunction. In addition, data transmission during the permission verification process is not hardware encrypted, posing a risk of interception or tampering. To address these issues, we propose a device permission management device. Utility Model Content

[0055] Working Principle: When this utility model is needed, the core functions of the device are implemented by modular components. The main control module 4 acts as the central hub, coordinating the work of the permission verification module 5, storage module 6, and communication module 7. The permission verification module 5 receives external permission requests and verifies them quickly through the high-speed processor 9. The storage module 6 stores permission data and operation records in real time, and the encryption chip 8 performs hardware-level encryption on the data to prevent leakage. The communication module 7 adapts to different industrial equipment through multiple interfaces, realizing cross-device synchronization of permission information. The hardware fixing components fix each module in the supporting protective shell 2 through the module mounting fixing plate 10 and the elastic snap-fit block 11, while supporting the individual disassembly and replacement of modules to meet the needs of functional upgrades. At the same time, the device achieves physical security protection through the closed self-locking component. When the sealing plate 3 is closed, the locking snap-fit protrusion 12 on its front side contacts the rotating support sleeve 17, the locking spring 13 pushes the locking rotating block 14, and the rotating locking rotating block 14 contacts, realizing the initial self-locking. In the limiting assembly, the limiting spring 16 pushes the limiting slide bar 15 into the groove of the locking rotating block 14, further restricting its rotation. When opening, a specific key needs to be inserted into the rotating hole of the sealing plate 3 of the cover. The groove of the key matches the triangular boss of the locking rotating block 14. When rotating, the limiting slide bar 15 is compressed and the locking rotating block 14 is disengaged from the locking latch boss 12, ensuring that only authorized personnel can access the internal module and resisting physical disassembly attacks. When an external device initiates an authorization request, the communication module 7 receives the signal and transmits it to the main control module 4. The authorization verification module 5 calls the authorization data in the storage module 6 and completes the comparison and verification in the high-speed processor 9. The encryption chip 8 encrypts the transmitted data in real time. After the verification is successful, the main control module 4 sends an authorization command to the device through the communication module 7 and simultaneously encrypts and stores the operation record. The device authorization management display screen 1 displays the authorization status, operation log and other information in real time, which is convenient for management personnel to monitor. If the verification fails, the system automatically records the abnormal request and triggers an early warning.
