DSC-DVS Distributed Fiber vibrometer (Perimeter)
DSC-DVS Distributed Fiber Optic Vibration Meter (Perimeter): This system is a distributed fiber optic vibration sensing system based on scattered light interference technology. It continuously and real-time monitors various disturbances directly acting on the fiber optic or transmitted to the fiber optic through load-bearing objects such as soil cover and fences.
technical parameter

1. The detection distance can reach 50km and accurately locate intrusion and leakage points;

2. Can achieve simultaneous monitoring of multiple points and events without affecting each other;

3. The system can directly use standard communication optical cables according to the environment configuration, and the monitoring area is divided according to the site;

4. Background pattern recognition, accurately determining intrusion events through pattern analysis;

5. Can be used in dangerous and harsh environments such as wind, rain, lightning, etc., with strong resistance to false alarms;

6. Open design facilitates data management and on-site control.

Application areas:

1. Monitoring of theft prevention and construction damage prevention for oil, gas, and coal pipelines;

2. Monitoring of urban underground gas, heating, and water pipeline leaks and prevention of construction damage;

3. Long distance fence intrusion prevention system, such as airports, warehouses, military restricted areas, border lines, etc;

4. Geological and structural change alarms, such as mine tunnel vibration and displacement, mountain and slope collapse warnings;

5. Accurate positioning of trapped personnel in mine accidents;

6. Other vibration alarm applications.
