DFOS Infrastructure
Safety Solution
![]() | The DFOS-based infrastructure safety solution is an integrated monitoring system that utilizes distributed fiber optic sensors to detect anomalies such as vibration, temperature, and strain in real time. It is linked with an AI video analysis system to identify and respond to potential hazards at an early stage. It can be applied to a wide range of infrastructures such as roads, tunnels, bridges, pipelines, and industrial complexes. The system automatically detects various risk factors—including intrusion, flooding, cracking, leakage, and displacement—enhancing infrastructure stability and maintenance efficiency. |
