1. Bagaimana Teknologi Penderiaan Getaran Gentian Optik Teragih Powers Pemantauan Infrastruktur Moden
1.1 Asas Pengesanan Getaran Teragih DVS
DVS (Penderiaan Getaran Teragih) teknologi beroperasi pada prinsip hamburan belakang Rayleigh dalam gentian optik. Apabila denyutan laser merambat sepanjang gentian, ketidakhomogenan mikroskopik menjana cahaya berselerak belakang. Getaran luaran menyebabkan perubahan kecil dalam indeks biasan gentian dan panjang, mengubah fasa cahaya yang tersebar. Sistem mengesan perubahan fasa ini untuk membina semula maklumat getaran pada setiap titik di sepanjang gentian, menjadikannya amat berkesan untuk mengesan getaran mekanikal frekuensi rendah dan gangguan tanah.

4. Soalan Lazim Mengenai Distributed Fiber Optic Vibration Analyzers
4.1 What is the maximum monitoring distance for DVS and DAS systems?
Standard DVS systems pantau 50 kilometer, with enhanced configurations reaching 80 kilometer. sistem DAS biasanya meliputi 30-40 kilometers in standard configurations, with high-end units extending to 50 kilometer. There’s an inherent trade-off between monitoring distance and spatial resolution: high-resolution configurations (1-2 meter) limit distance to 20-30 kilometer, while lower resolution settings (10 meter) enable 80-kilometer monitoring ranges.
4.2 How accurate is the localization capability of distributed fiber optic vibration monitoring?
DVS systems achieve localization accuracy of ±10-20 meters with spatial resolutions of 5-10 meter, sementara sistem DAS deliver ±5-10 meter accuracy with 1-5 meter spatial resolution. Localization precision depends on fiber length measurement accuracy (±0.1%), laser pulse width stability (±5%), and sampling clock precision (±10ppm).
4.3 Are there special requirements for fiber optic cable types?
Standard G.652 single-mode fiber satisfies most applications. Special environments may require: high-temperature fiber (-40 to 200°C), metal-armored cable (tensile strength >2000N), PE-sheathed cable (compression >3000N/100mm), or ADSS self-supporting aerial cable (span 50-300 meter).
