DISASTER SAFETY AI SOLUTION

e-DAS

Acoustic vibration data detection through Rayleigh scattering

Distributed optical sensors (optical cables for communications) are installed in measurement sections to continuously measure acoustic vibrations,
temperature, and other parameters. These collected data are analyzed and monitored in real time to detect any anomalies.

e-DAS, a new beginning of safety

e-DAS uses an optical fiber cable as sensors to measure the distribution forms of physical quantities (acoustic vibrations, temperature, deformation, etc.) across the entire sections of the optical cable (sensor). Based its generated optical signals, the system receives and analyzes backscattered light signals generated by the optical cable (sensor) to measure physical quantities at different points along the cable.

Reasons to choose e-DAS

By measuring physical quantities such as acoustic and vibration changes over long distances and continuous or specific sections, this product overcomes the limitations of traditional monitoring systems. It helps to prevent safety accidents by detecting abnormal vibrations in real time across various facilities and structures.
