DVS
The DVS (Distributed Vibration Monitoring System) is an advanced fiber-optic sensing solution purpose-engineered to achieve high-efficiency, long-distance, real-time, and high-precision monitoring of critical assets including oil & gas pipelines, perimeters of secure facilities, and various large-scale critical infrastructure.
By utilizing standard communication optical fiber as the core sensing medium, DVS enables full-range, uninterrupted detection and in-depth analysis of micro-vibrations along the entire fiber length. This capability allows the system to accurately identify abnormal disturbance signals in a timely manner, thereby providing stable, highly reliable early warning for potential intrusion attempts, pipeline leakage accidents, and a wide range of unauthorized or anomalous activities.
Product Features
Core Performance & Precision
Long distance measurement: detection distance up to 40km, precise localization of intrusion points and leakage points.
High-precision and sensitive: system parameters are configured according to the environment, standard communication fiber optic cable can be used directly, and the monitoring area is divided according to the site.
Rapid response: scanning cycle as low as 0.1s.
Monitoring Capability
Real-time: 7×24 hours real-time monitoring, micro-vibration in the area to be measured to locate temperature anomalies, real-time early warning.
Distributed Measurement: Multi-point and multi-event monitoring at the same time, without affecting each other.
Environmental Adaptability & Stability
Strong stability: wind and rain, lightning, ice-covered and other dangerous and harsh environments to use, anti-false alarms.
Safety & Intelligence
Quality and safety: the average power of laser pulse transmitted by fiber is low, even if the fiber is broken, it will not produce any danger.
Intelligent without guarding: the system detects anomalies and sends reports to the direct person in charge via SMS and Internet. Easy data management on-site control.
Pipeline Vibration Detection
Feel the vibration around the pipeline through DVS, and analyze and judge the information to exclude general interference, and finally generate an alarm.
