Distributed Fiber Optic Acoustic Vibration Sensing System/Pipeline Leakage Monitoring

1、 System Overview:

In smart cities and long-distance water transmission and distribution processes, leakage in smart pipeline systems is a global problem, and leakage control is a global challenge. MH-FS5000Distributed Fiber Optic Acoustic Vibration Sensing System/Pipeline Leakage MonitoringIt can effectively detect PCCP pipeline wire breakage, as well as provide early warning of possible pipe burst events, and also provide early warning of pipeline damage around the pipeline, such as excavator operations.

2、 System principle:

Developed based on the principles of coherent Rayleigh scattering and optical time-domain scattering, it has the ability to monitor multiple vibration events over long distances, in a distributed and real-time online manner, with precise positioning by colleagues. The detection distance can reach 50Km. The positioning accuracy can reach ± 5 meters, and higher accuracy can be customized. Being able to monitor vibrations along the fiber optic cable and capture sound sources, the fiber optic cable operates as if a large number of amplifiers are installed. Classification algorithms are used for monitoring sound restoration and locating intrusion activities.
