Our Distributed Acoustic Sensing (DAS) system leverages the high sensitivity of narrow-linewidth single-frequency lasers to strain-induced coherent Rayleigh scattering in optical fibers. By integrating the principles of optical time-domain reflectometry (OTDR), our DAS solution enables long-range, high spatial and temporal resolution sensing of environmental vibrations and acoustic fields that interact with the fiber.
We also provide a professional DAS data analysis software platform. Utilizing AI algorithms and precise DAS-based localization, it delivers highly reliable monitoring performance across various applications.
Key Features
Our Distributed Acoustic Sensing (DAS) solutions are divided into two main categories: oil well logging applications and pipeline monitoring applications.
The iDAS series is specifically designed for pipeline monitoring, offering three configurations based on sensing distance: 5 km, 20 km, and 50 km. These options allow flexible deployment for various pipeline lengths and environments, enabling real-time detection of leaks, intrusions, and other anomalies with high accuracy and reliability.
1. Real-time vibration signal phase curve display
Real-time display of the phase demodulation signal at each vibration point.
2. Real-time sound signal display at any point in the time domain
By selecting any point on the vibration optical cable, the real-time sound signal at that point can be monitored.
3. Spectrum analysis
Frequency analysis of any selected point on the vibration optical cable, used to analyze signal spectrum and signal type.
4. Pattern recognition
Precise analysis and identification of excavators, electric drills, iron picks, iron hammers, vehicles, etc.
5. Full-fiber length waterfall diagram
Clearly displays sound signals collected at different locations, providing an intuitive view of monitoring conditions along the entire fiber length.
6. Signal Filtering
Select signal filtering types and cutoff frequencies to easily obtain effective data.
7. Data Storage
Choose real-time storage, time-segment storage, or other methods as needed.
8. Data Playback
Playback stored sound data.
