[0030] Please refer to Figures 1-5 as shown, an intelligent power grid inspection terminal provided by an embodiment of the present invention includes: a mounting bracket 1, a guide rail 2, a driving device 3, a data connector 4 and a camera 5; The driving device 3 is movably arranged on the guide rail 2, and the data connector 4 is fixed below the driving device 3 and electrically connected to the camera 5; The data connector 4 integrates a communication module 27 and a network optimization module 28. The communication module 27 is used to transmit inspection data through heterogeneous communication links; the network optimization module 28 is used to realize dynamic switching of communication modes, transmission fault tolerance control and link state monitoring.

[0031] Specifically, in the embodiment of the present invention, a groove 9 is formed at the top of the driving device 3. Two support plates 10 are symmetrically and fixedly connected inside the groove 9. A driving wheel 11 is connected to the inside of the support plate 10 through a rotating shaft. The driving wheel 11 is in contact with the bottom of the guide rail 2. A driving motor 12 is fixedly connected to the outside of one of the support plates 10. The driving motor 12 is connected to the rotating shaft.

[0032] Fixing sleeve plates 13 are symmetrically and fixedly connected to the driving device 3. A cover plate 30 is connected to the fixing sleeve plates 13 through screws. Protruding limiting strips 14 are provided on the sides of the cover plate 30 and the fixing sleeve plates 13 close to each other. Moving rods 15 are symmetrically and slidably connected inside the fixing sleeve plates 13 and the cover plate 30. Limiting grooves 16 are formed on both sides of the moving rods 15. The limiting grooves 16 cooperate with the protruding limiting strips 14. One end of the moving rod 15 extends to the outside of the fixing sleeve plate 13. Teeth are provided at one end of the moving rod 15. Half-tooth rings 19 are symmetrically and rotatably connected inside the fixing sleeve plates 13. The half-tooth rings 19 are meshed with the corresponding moving rods 15 through the teeth. Connecting rods 20 are rotatably connected to one ends of the moving rods 15.

[0035] During use, the mounting frame 1 is installed and fixed. Then, the guide rail 2 is pushed to move through the first electric push rod 8 to adjust the height of the guide rail 2. After that, the driving rod 17 is pushed to move through the second electric push rod 22, driving the half-tooth ring 19 to rotate, so that the half-tooth ring 19 meshes with the moving rod 15 to drive the moving rod 15 to move.

Finally, the driving motor 12 drives the driving wheel 11 to rotate, so that the driving wheel 11 contacts the bottom of the guide rail 2, thereby driving the camera 5 to perform mobile inspection.

[0036] Another example is Figure 6As shown, the Power Harmony operating system module 23 is also integrated inside the data connector 4. The Power Harmony operating system module 23 specifically includes a distributed task scheduling unit 2301, a power consumption optimization unit 2302, and a device adaptation unit 2303, where: The distributed task scheduling unit 2301 is mainly responsible for collaborative scheduling and management of tasks in a multi-device environment.

For example, in the application scenario of multi-device collaborative inspection in the power system, multiple inspection robots or sensors need to work together to comprehensively inspect and monitor power equipment. The distributed task scheduling unit 2301 can ensure reasonable task allocation among these devices, avoid duplicate labor and resource waste, and improve the inspection efficiency.

[0037] The power consumption optimization unit 2302 optimizes the power consumption of the device by dynamically adjusting the operating state of the device, thereby extending the battery usage time. It can intelligently adjust the operating mode of the device according to the actual workload and environmental conditions of the device, such as reducing the CPU frequency, turning off unnecessary hardware modules, etc.

[0038] The device adaptation unit 2303 is mainly responsible for supporting the special protocols and interfaces in the power system to ensure that the device can seamlessly access and run in the Power Harmony operating system. It can identify and adapt the communication protocols and data formats of various power devices, provide a unified interface and standard, and simplify the integration and management of devices.

[0039] Please refer to Figure 7 As shown, the security module 24 is also integrated inside the data connector 4. The security module 24 specifically includes: a data encryption unit 2401, an identity authentication unit 2402, and a permission management unit 2403, where: The data encryption unit 2401 encrypts the data using the TLS / SSL protocol to ensure the security and confidentiality of the data during transmission; The identity authentication unit 2402 supports two-factor authentication (2FA) and confirms the user identity by combining two different verification methods to improve the security of the system; The permission management unit 2403 assigns corresponding operation permissions according to the roles and responsibilities of users to ensure that users can only access and operate resources related to their roles. The permission management unit prevents unauthorized operations and data leakage through fine-grained permission control.

[0040] Please refer to Figure 5 As shown, the data processing module 25 and the data caching module 26 are also integrated inside the data connector 4. Again, Figure 8 As shown, the data processing module 25 specifically includes: an image processing unit 2501 and an AI analysis unit 2502, where: The image processing unit 2501 is used for image compression and noise reduction, specifically: reducing the size of the image file through algorithms, reducing the storage and transmission costs, while trying to maintain the image quality; and removing the noise in the image through algorithms to improve the clarity and usability of the image.

[0041] The AI analysis unit 2502 integrates a deep learning model and can perform intelligent analysis on the status of power equipment, automatically identifying potential faults or anomalies. Through learning a large amount of historical data, the deep learning model can accurately identify abnormal patterns during equipment operation and give early warnings or diagnostic results.

[0042] Please refer to Figure 9 as shown, the communication module 27 specifically includes: a mobile network unit 2701, a WIFI module 2702, and a power line carrier module 2703, where: The mobile network unit 2701 uses the mobile network for remote data transmission, supporting communication between the device and a remote server or other devices. The mobile network unit 2701 can cover a wide area, ensuring the stability and reliability of data transmission over long distances; The WIFI module 2702 supports wireless communication within a local area network and uses WIFI technology to achieve fast data transmission between devices. The WIFI module 2702 has the characteristics of high bandwidth and low latency, and is suitable for efficient data exchange within a local area; The power line carrier module 2703 uses the power line as a communication medium to achieve direct communication between power equipment. The power line carrier technology realizes data transmission by superimposing high-frequency signals on the power line without the need for additional communication lines.

[0043] Please refer to Figure 10 as shown, the network optimization module 28 specifically includes: a multi-channel communication switching unit 2801, a resume interrupted transfer unit 2802, and a heartbeat data transmission unit 2803, where: The multi-channel communication switching unit 2801 supports automatic switching between multiple communication methods such as 4G / 5G, WiFi, and power line carrier, ensuring the continuity and stability of data transmission. When the signal of the current communication method is weak or interrupted, the multi-channel communication switching unit can automatically switch to other available communication methods to avoid data loss or transmission interruption.

[0044] The resume interrupted transfer unit 2802 can cache the data that has not been completely transmitted when the network is interrupted and automatically resume transmission from the breakpoint when the network resumes, ensuring the integrity and continuity of the data. The resume interrupted transfer technology can effectively avoid data loss or repeated transmission caused by network fluctuations.

[0045] The heartbeat data transmission unit 2803 detects the network connection status by periodically sending heartbeat packets. A heartbeat packet is a small data packet used to confirm whether the connection between the device and the server is normal. If the heartbeat packet fails to respond in time, the unit will trigger a network status detection or switching mechanism.

[0046] Compared with the prior art, the beneficial effects brought by the embodiments of the present invention are as follows: Through the multi-modal communication dynamic switching mechanism and network optimization technology, the present invention significantly improves the stability of data transmission in complex electromagnetic environments. Among them, the adaptive communication link switching strategy based on channel quality, combined with the function of resume interrupted transfer and real-time link monitoring, effectively reduces the risk of data packet loss and ensures the integrity and continuity of inspection data. At the same time, the device status analysis engine driven by deep learning and the multi-level image processing algorithm work together to achieve high-precision identification of device surface defects and intelligent classification of typical faults, greatly improving the accuracy of fault detection. And a prediction model is constructed through time series feature analysis to early warn potential device anomalies. In addition, the modular decoupling architecture separates the communication, computing, and mechanical control functions, while optimizing the system response efficiency, supports multi-terminal collaborative task scheduling, significantly improves the inspection coverage efficiency, reduces the operation and maintenance costs, and provides high-reliability and multi-dimensional device status perception and diagnosis capabilities for the smart grid.
