Distributed Acoustic Sensing (DAS)
DAS Sensing
Distributed acoustic sensing system (DAS) is a common technology in fileds of oil and gas industry to proof pilferage, detect pipeline leaks, and monitor drilling. DAS's interrogator units are connected to fiber optic cables, turning them into acoustic sensors, realizing real-time monitoring of railway lines over 50 km continuously.
It is suitable for many railway use cases, such as trains postioning, infrastructures monitoring, defective wheels detecting, and obstacles identifying.
What Are The Das Technology's Advantages?
Continuous and distributed measurement of temperature and vibration, no measurement blind area
Multi-event simultaneous detection and accurate positioning
The optical fibre is the sensor, which combines transmission and sensing in one
60km ultra-long measurement distance, rich measurement information
Fast response, an alarm within 1 second
Optical signal transmission, complete electrical insulation, anti-electromagnetic interference
Intrinsically safe, suitable for long-term work inflammable and explosive environments
The measurement is stable and reliable, and the false alarm rate is low
The optical fibre has a long service life, up to 30 years maintenance-free
