[0020] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0021] Please see Figure 1 This utility model provides an intelligent inspection system for power transmission lines using unmanned aerial vehicles (UAVs), including a multi-mode communication unit, an airborne control unit, and a camera module, wherein the airborne control unit is signal-connected to the camera module;

[0022] The multi-mode communication unit is used to provide data transmission services to a single station, to control multiple local detection devices wirelessly or wiredly, and to provide low-bandwidth but high-coverage communication support for remote or extreme environments where terrestrial networks cannot cover.

[0023] It should be noted that the multi-mode communication unit includes a MESH communication module, a 4G public network module, and a narrowband satellite communication module. The MESH communication module supports MESH networking and can adopt a MESH module + wireless router module + switch equipment solution to enable a single station to provide data transmission services and has local wired / wireless (WiFi) control (PC or mobile phone) functions.

[0024] The narrowband satellite module is configured as the Tiantong IoT terminal QX-M1;

[0025] By using a multi-mode communication unit, during routine drone inspections, the MESH communication module is prioritized for point-to-point image and data transmission, providing real-time feedback of images, videos, drone position, and attitude. If the MESH communication module signal is lost, it can automatically switch to the 4G public network module with a switching time of no less than 500ms to continue transmitting data. If both the 4G public network module and the MESH communication module signal are lost, narrowband satellite will transmit the aircraft's position and attitude in real time. This multi-network switching capability ensures that the drone can maintain real-time communication with the ground station APP, effectively preventing signal loss.

[0026] The airborne control unit is used to execute instructions and control the camera module to take pictures.

[0027] In this embodiment, the camera module can support high-resolution imaging, high dynamic range imaging, and precise positioning and navigation;

[0028] The camera module also includes a gimbal, which is configured as a controllable gimbal. The gimbal is compatible with multiple drone platforms and has a built-in high-precision GPS and IMU unit, which can provide geographical location information and seamlessly integrate with image data. The gimbal is fixedly installed on the drone.

[0029] It should be noted that the camera module is a Phase One P3.

[0030] The use of a camera module can provide accurate geographic location information, which, when combined with images, facilitates subsequent data processing and analysis. It supports high dynamic range imaging technology, enabling the acquisition of high-quality images under various conditions, ensuring the reliability and accuracy of the data.

[0031] In this embodiment, the airborne control unit is connected to a ground station APP via a multi-mode communication unit signal. The ground station APP can operate and manage the camera module, and is used for image preview, image capture and gimbal control, as well as log output.

[0032] In this embodiment, the airborne control unit is equipped with sky-end software. The ground station APP transmits data information to the sky-end software of the airborne control unit through a multi-mode communication unit. The airborne control unit communicates with the gimbal and camera module through the MAVLink protocol according to the data instructions received by the sky-end software, and controls the gimbal to rotate up, down, left, and right and the camera module to take pictures.

[0033] The ground station app allows for real-time preview of images and drone status, FTP access, photo taking, log downloading, focus settings, image preview, camera status, mesh status, and gimbal control. Through the app interface, users can preview high-resolution images captured by the camera module in the sky, ensuring image quality and accurate shooting angles. The app also supports one-click capture, allowing users to quickly obtain the desired images. Furthermore, it allows gimbal control, enabling users to flexibly adjust camera shooting angles for precise multi-angle and multi-directional shooting. The app also features powerful log output capabilities, comprehensively recording the operation process and system status, providing strong support for subsequent data analysis and troubleshooting.

[0034] Specifically, the working principle of this UAV-based intelligent power line inspection system is as follows: Control signals are transmitted through the ground station APP interface, data is received through the multi-mode communication unit, and command information is transmitted to the airborne control unit. The airborne control unit controls the camera module and gimbal to perform corresponding command operations, and the data is transmitted back to the ground station APP by the multi-mode communication unit. Users can preview images and UAV status in real time, receive data via FTP, take photos, download logs, and set focus, image preview, camera status, MESH status, and gimbal control.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
