Commonly Used Equipment

Matrice 30T: Highly integrated body, compact storage size, easy to carry, ready to deploy quickly. It integrates wide-angle, zoom, thermal imaging, and laser rangefinder sensors, ensuring targets are captured whether near or far, day or night. The 16x optical zoom camera allows comprehensive inspection of wires, insulators, towers, and fittings from a safe distance. Equipped with six-direction obstacle avoidance, redundant design, and low-light smart photography, it ensures autonomous flight inspection.
M300 RTK: A long-endurance, highly mobile flight platform paired with hybrid sensor payloads, leveraging intelligent functions and human-machine interaction for safe and reliable operations that enhance efficiency. Often equipped with the Zenmuse L2 LiDAR, it collects "point cloud" data while flying over transmission line corridors. The data is processed through DJI Terra point cloud software to generate 3D corridor models, significantly improving inspection accuracy.
Mavic 2 Enterprise Advanced: A simple-to-operate, efficient, and portable industrial-grade flight platform. It can carry high-definition thermal and high-pixel visible light cameras, supports 32x digital zoom, and includes an RTK module for centimeter-level positioning, enabling efficient insight into job site details.

Inspection Content and Advantages

Inspection Content:
Visual Inspection: Using the drone's visible light camera, high-definition images are taken of high-voltage wires, insulators, towers, and other facilities to check for damage, deformation, corrosion, or foreign objects.
Infrared Thermal Imaging: The thermal camera detects temperature distribution at wire joints, insulators, and other parts, identifying overheating issues such as poor connections or deteriorating insulators that could lead to failures.
3D Modeling and Spatial Measurement: Using LiDAR or image-based 3D reconstruction, a 3D model of the transmission line corridor is created. Parameters like tree-line distance, sag, and conductor wind deviation are measured, providing accurate data for safety assessment and maintenance.

Equipment Advantages:
Efficiency: Compared to traditional manual inspections, drones can quickly cover large areas, greatly improving efficiency and reducing labor and time costs.
Safety: Eliminates risks for inspectors working at heights, especially in complex terrain, harsh weather, or hard-to-reach areas like rivers and valleys, allowing safe inspection missions.
Accuracy: Drones equipped with high-resolution cameras and thermal imagers capture clear, precise images and data. Close-range shooting and detection enhance fault identification accuracy.
Real-Time Capability: Through wireless communication, drones transmit images and data to ground control stations in real time, enabling prompt issue detection and decision-making, improving emergency response.
Flexibility: Drones can adjust inspection routes and tasks as needed, unrestricted by terrain or traffic conditions. They quickly reach designated locations, offering significant advantages for临时增加的巡检任务或突发情况的应急巡检.
