The equipment is designed specifically for natural gas leak detection, integrating high-sensitivity laser methane detection, 10x optical zoom lens, and 1200m laser ranging module. It supports remote control of drones and real-time data display, and can achieve ultra long distance detection of 200m and penetrate 5 layers of glass to detect leaks in the room. By using a 5-megapixel high-definition lens and a three-axis gimbal, multiple detection modes such as Z-scan and spiral scan can be executed, synchronously transmitting high-definition images and automatically recording the precise coordinates of the leakage point. The system has real-time alarm function and automatically generates visual inspection reports containing geographic information, effectively preventing safety accidents while significantly improving detection efficiency and reducing operation and maintenance costs, providing a complete data traceability system for natural gas facility safety management.The high-altitude detection method can flexibly detect natural gas devices in areas that are difficult for personnel to reach, effectively reducing the intensity of manual inspection work and improving inspection efficiency.
