Description

Technical Field

[0001] The present invention relates to the technical field of port locks, and more particularly to a passive intelligent RJ45 port lock structure for supporting an intelligent pole-mounted circuit breaker. Background Art

[0002] As a key device in the distribution network, the pole-mounted circuit breaker undertakes the important tasks of controlling and protecting power lines. With the development of the intelligentization and informatization of the power system, the pole-mounted circuit breaker has an increasing dependence on network connection, and the security protection of its network ports has become a key link to ensure the stable operation of the power system. At present, the network port protection of the pole-mounted circuit breaker faces many challenges, as follows: Failure of traditional protection means: Traditional network port security protection methods, such as posting "Do not access" seal stickers, have almost no practical protection effect for pole-mounted circuit breakers. Pole-mounted circuit breakers are usually installed outdoors with a complex environment, and the seals are easily damaged and fallen off. Moreover, this method can only play a warning role and cannot prevent illegal access by external personnel. It has no defensive ability against malicious attacks and is difficult to ensure the security of the network ports of pole-mounted circuit breakers.

[0003] Obvious limitations of mechanical protection: Although the mechanical network port plug enhances the protection to a certain extent, it has prominent problems when applied to pole-mounted circuit breakers. On the one hand, it can only protect idle network ports, and in the actual operation of pole-mounted circuit breakers, many ports are in use, and the mechanical network port plug cannot protect them. On the other hand, its unlocking tool is simple and easy to imitate, and it is easily cracked by violence. One key can open multiple network port plugs, which poses a great security risk to outdoor pole-mounted circuit breakers and may lead to easy access by illegal devices, disrupting the normal operation of the power system.

[0004] Shortcomings of software protection: Software security protection means, such as MAC address binding and port access control systems, also have deficiencies in the network port protection of pole-mounted circuit breakers. Due to the harsh working environment of pole-mounted circuit breakers, they may face contact-based network attacks on ports. The software protection lacks effective port-level hardware protection support and cannot fundamentally solve problems such as contact-based attacks, unauthorized external connections, and accidental network cable unplugging. When network anomalies occur, it is difficult to quickly locate and solve problems, affecting the reliability and stability of the power system.

[0005] Insufficient existing hardware protection: Currently, the hardware protection technology for network ports has serious defects when applied to pole-mounted circuit breakers. These hardware protections are simply mechanical locks, lacking the capabilities of directional unlocking and intelligent traceability, and unable to meet the complex management requirements of pole-mounted circuit breakers. They can still only act on idle network ports, unable to achieve full coverage protection for the network ports of pole-mounted circuit breakers. Moreover, there is no linkage defense mechanism between the mechanical lock and the system, unable to detect and respond to security threats in a timely manner, and it is difficult to ensure the safe and stable operation of the power system. Summary of the Invention

[0006] The purpose of the present invention is to provide a passive intelligent RJ45 port lock structure for supporting intelligent pole-mounted circuit breakers, which can achieve port-level anti-violence protection design, provide plug-in protection and anti-violence protection, and enhance targeted hardware protection capabilities. And it can achieve enhanced intelligent lock control protection based on internal network key distribution, which not only improves the security protection capabilities but also enhances the management levels of refined operation and maintenance and precise operation, and provides zero-trust control capabilities.

[0007] To achieve the above purpose, the present invention provides a passive intelligent RJ45 port lock structure for supporting intelligent pole-mounted circuit breakers, including a lock body, a lock core, and a lock control.

A working indicator light, a key, and a charging indicator light are respectively provided on the upper surface of the housing.

[0009] Preferably, the network end interface device includes an external network cable crimping terminal, and a network cable fixing buckle is provided at the port of the external network cable crimping terminal.

[0022] Embodiment As Figures 1-3 shown, the present invention provides a passive intelligent RJ45 port lock structure for supporting an intelligent pole-mounted circuit breaker, including a lock body 3, a lock core 4 and a lock control 5. One end of the lock body 3 is connected to the lock core 4. A lock tongue 6 is provided at the center of the upper surface of the lock core 4. A TYPE-C data interface 7 is provided at the center of the other end of the lock body 3. The TYPE-C data interface 7 is inserted and connected to the lock control 5. An indicator light 8 is provided above the TYPE-C data interface 7. The lower part of the TYPE-C data interface 7 is connected to the network terminal interface device 4 through a circuit.

[0023] The lock control 5 includes a housing 51. One end of the housing 51 has a front cover 52, and a TYPE-C data plug 53 is provided at the center of the outer surface of this side. A charging interface 54 is provided at the center of the other end of the housing 51. A working indicator light 55, a button 56, and a charging indicator light 57 are respectively provided on the upper surface of the housing 51.

[0024] The network interface device 4 includes an external network cable crimping terminal 1, and a network cable fixing buckle 2 is provided at the port of the external network cable crimping terminal 1.

[0025] As Figure 4 shown, a control system is provided inside the lock control 5. The control system is based on an integrated asynchronous event-driven framework. The integrated asynchronous event-driven framework includes a microprocessor, a multi-time-base software timer, a memory, and other built-in components, which will not be elaborated here. The microprocessor, the multi-time-base software timer, and the memory are all connected to a drive interface, and the drive interface is connected to the underlying hardware devices.

[0026] Based on a lightweight embedded framework, it provides a unified underlying device driver model and basic service functions, featuring modular design, configurability, and scalability, and supporting basic kernel functions such as mutex locks and object management. It integrates services such as an asynchronous event-driven framework (event) and a multi-time-base software timer (soft-timer). It accesses the underlying hardware devices through a unified drive interface (open, close, ioctl, read, write), decoupling the underlying driver and the application.

[0027] It adopts a passive design, with a high-speed intelligent chip built-in. It uses a portable electronic key to unlock, so it has a very low power consumption design requirement. The microprocessor generally supports the sleep mode. The sleep mode of the microprocessor based on the Cortex-M series is enhanced, supporting the sleep mode, the attempt-to-sleep mode, and the deep sleep mode, and it is determined by the special bit of the system control register inside the processor.

[0028] For different device driver libraries, the access mode can be configured. The power consumption design depends on the chip system design. Different power consumption design processing methods may affect the clock signal processing, the voltage change of the memory block, etc. At the same time, the portability of multiple microcontrollers also needs to be considered to achieve the power consumption optimization design of the comprehensive performance.

[0029] As Figure 5 shown, the microprocessor executes the SM2 elliptic curve public key cryptography algorithm. The SM2 elliptic curve public key cryptography algorithm includes the SM2-1 elliptic curve digital signature algorithm, the SM2-2 elliptic curve key exchange protocol, and the SM2-3 elliptic curve public key encryption algorithm, which are respectively used to implement the functions of digital signature, key negotiation, and data encryption.

[0030] The SM2 elliptic curve public key cryptography algorithm is a public key cryptography algorithm independently designed in China, including the SM2-1 elliptic curve digital signature algorithm, the SM2-2 elliptic curve key exchange protocol, and the SM2-3 elliptic curve public key encryption algorithm, which are respectively used to implement functions such as digital signature, key negotiation, and data encryption. Different from the RSA algorithm, the SM2 algorithm is based on the discrete logarithm problem of the point group on the elliptic curve. Compared with the RSA algorithm, the cryptographic strength of 256-bit SM2 is already higher than that of 2048-bit RSA.

[0031] The present invention adopts a combined protection improvement method of an intelligent network port lock (hard isolation) + switch software shutdown (soft isolation). The intelligent network port lock is used as the smallest unit for the refined management of the power private network port-level security protection. Each intelligent network port lock has a unique ID, and it is impossible to pull out the intelligent network port lock from the network port without system authorization.

[0032] Through the intelligent network port lock key distribution system, remote unlocking applications and unlocking record traceability can be carried out, the protection status of all ports of the current device can be displayed, each port can be monitored, and the whole process of network security port-level protection can be controlled, realizing physical isolation of the in-use network ports and idle network ports with network cables plugged in, and carrying out refined, standardized, and visual management, eliminating the network security hidden dangers brought about by the intrusion of the switch body itself, rather than the traditional network port plug that can only be used for dust prevention and cannot prevent intrusion and lacks refined management means.

[0033] The intelligent key distribution and visual lock state management system can perform port-level precise operation and maintenance authorization, provide traceability records by technical means, and the information security prevention and control will be upgraded from "device-level protection" to "port-level protection", greatly improving the refined operation and maintenance management level.

[0034] The pole-mounted circuit breaker needs to rely on the network to realize functions such as remote monitoring and data transmission during the operation of the power system, which depends on various network ports. The passive intelligent RJ45 port lock structure in the text is precisely for the protection of the RJ45 network port of the pole-mounted circuit breaker. Through the coordinated work of the lock body, lock core, and lock control, illegal access can be effectively prevented. In the power private network environment, it can prevent unauthorized personnel from randomly plugging and unplugging network cables and prevent external malicious devices from accessing the network port of the pole-mounted circuit breaker, thus ensuring the security of data transmission and the stable operation of the device.

[0035] The lock tongue design on the lock core is an important protection mechanism. In the application scenario of the pole-mounted circuit breaker, the lock tongue can cooperate with the network port structure. When the lock core is locked, the lock tongue blocks the network port, preventing the network cable from being accidentally pulled out or illegally inserted. This design can ensure that during the operation of the pole-mounted circuit breaker, the network connection is stable and reliable, avoiding problems such as data transmission interruption and network attacks caused by network cable loosening or illegal plugging and unplugging.

[0036] The control system inside the lock control is based on an integrated asynchronous event-driven framework, and the microprocessor executes the SM2 elliptic curve public key cryptography algorithm. In the management of pole-mounted circuit breakers, this system can achieve intelligent lock control protection based on intranet key distribution. Through the key distribution system, managers can remotely apply for unlocking and record the unlocking operations for easy traceability. It can also monitor the port protection status in real time, realizing refined and visual management of the ports of pole-mounted circuit breakers, and improving the security and operation and maintenance management level of the power private network.

[0037] The external network cable crimping terminals and network cable fixing buckles of the network-side interface device can ensure a firm connection between the network cable and the port in the usage scenario of pole-mounted circuit breakers. It can prevent the network cable from loosening due to external factors such as wind blowing and vibration, ensuring the stability of the network connection and providing a reliable physical connection basis for the data transmission of pole-mounted circuit breakers.

[0038] Therefore, the present invention adopts the above-mentioned passive intelligent RJ45 port lock structure for a supporting intelligent pole-mounted circuit breaker, implements the concept of "hard isolation protection, zero trust management", prevents social engineering intrusion, improves technical defense capabilities, alleviates the pressure on human defense, and greatly improves the security of the power private network; realizes the transformation from "coarse equipment-level operation and maintenance to fine port-level operation and maintenance", avoids accidental network cable plugging and unplugging events, reduces the accident probability, saves emergency repair costs and labor costs, and improves the stability and reliability of the power private network.

[0039] The present invention can build a port-level and hardware-level security protection system reinforcement, strengthen the company's network security defense line, and promote the transformation and upgrading of social engineering intrusion prevention means from human defense to technical defense.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present invention, and these modifications or equivalent replacements do not make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present invention.
