Long distance distributed Brillouin optical fiber sensing monitoring system
The long distance distributed Brillouin optical fiber sensing monitoring system uses the differential pulse pair technology, which has a higher signal to noise ratio and precision.
1mor2mMeasurements of the spatial resolution of the strain and temperature. It has the advantages of high insulation, anti electromagnetic radiation, corrosion resistance and long measurement distance.
It has a wide range of applications and can be used for on-line monitoring of power cables, monitoring of oil and gas pipelines, monitoring of underground pipelines, and the junction of large buildings.
Health monitoring, substation monitoring and so on.
(1) optical fiber cable. According to the actual situation of the measured objects, the optical cable and the measured object are laid out accordingly, and the temperature of the measured object is carried out through the optical fiber cable.
2. Sensing host. The laser emission, reception, data acquisition, data analysis and processing are completed to form the temperature, strain, and position of the measured object.
Information, and local graphical display, analysis, alarm.
3. Comprehensive monitoring and management platform. All kinds of applications for safety early warning of measured objects are completed.
