Features:

oil and gas pipeline, natural gas pipeline, heating and water supply pipeline and other application environment distributed optical fiber vibration sensor monitoring system, long-distance detection.

System features:

1. The system can detect the whole process for a long distance, and each optical fiber signal processor can monitor the distance of 30 km.

2. The system can carry out accurate vibration monitoring in a long distance.

3. Due to the principle of distributed optical fiber Raman scattering, it is not affected by the power fluctuation of light source and the system loss caused by fiber bending and other factors, so the distributed optical fiber sensor has very good reliability and stability.

4. The intelligent vibration analysis system can detect and analyze whether the pipeline operation of each section of monitoring section encounters excavation, drilling and other actions. It can provide accident report in real time continuously and report the correct position of infringement. The sensitive analysis system can provide the nature of pipeline damage.

5. The leakage vibration monitoring system can record the normal operation data and accident records, so as to improve the operation environment and prevent the occurrence of accidents through analysis, which is not achieved by the traditional alarm monitoring system.

6. The leakage vibration monitoring system is not affected by the environment where the pipeline is located, whether it is laid under the noisy city or industrial area, or under the quiet wilderness, and is not subject to external interference such as electromagnetic wave. It is corrosion-resistant and can work in harsh chemical environment.

7. The leakage vibration monitoring system uses common communication optical fiber cable, which is composed of core optical fiber, with low cost.

Compared with 1-core optical cable, it has more advantages in intelligent analysis and false alarm prevention.

8. The system mainly includes: the pipeline optical fiber early-warning system is composed of optical fiber early-warning host, optical fiber early-warning terminal, on-site early-warning unit (substation), etc. in this system, the field early-warning unit (substation) is composed of optical fiber vibration detector, communication optical cable, front and rear end optical processing module and auxiliary equipment.The price is reasonable, the installation is simple, and can be compatible with other security technology equipment, such as video transmission system, sound alarm, etc.The damaged optical fiber can work normally only by welding. The optical fiber is not oxidized and rusty. It has high flexibility and corrosion resistance, and its service life can reach several decades.Product advantages: the front end of the system does not need power supply, the system adopts passive sensor, and the front end of the system does not need power supply. It is suitable for places with inflammable, explosive and inconvenient power supply lines and the perimeter of strong electromagnetic interference environment.

Reduce the construction and maintenance costs, because the front-end of the defense zone does not need to lay power signal lines, which reduces the construction cost, but also avoids the system failure caused by the aging of the line, and reduces the maintenance cost.

Detection rate 100%

The optical cable is used as the sensing unit, and the computer is used to collect and identify the data, and realize the detection of long-distance and large-scale defense area. The detection rate is 100%.

The front-end sensor to avoid lightning stroke uses vibration sensing optical cable, which is not subject to electromagnetic interference and electromagnetic radiation, and effectively avoids the damage of lightning to the system and the impact on other systems.

The system has built-in intelligent algorithm to effectively control the false alarm rate. The intrusion signal is compared with the signal database of the system to analyze and judge whether it is the real intrusion signal. It has a qualitative breakthrough in solving the problem of product false alarm, and can effectively shield interference signals such as bird dropping and tree branch shaking.

The main system is concentrated in the control room to avoid the damage to the main system by intrusion damage, which greatly reduces the maintenance cost of system damage and increases the service life of the system.

It supports multiple defense zones to alarm at the same time. Each defense zone independently analyzes the signal and operates independently. When someone invades from different defense areas at the same time, the invaded defense area can alarm at the same time without affecting each other.(the parameters of each defense area can be set separately according to the different environment of each defense area.)Excellent relay box and terminal box are selected as the front-end system material, and its shell is made of engineering plastic, which has the advantages of waterproof, anticorrosion, pressure resistance, high-performance, high-performance, high-performance, low-cost and low-cost

Impact resistance.(combined with the characteristics of the laying environment, change the appearance of the equipment color, carry out personalized design.Beauty and concealment)

It is suitable for severe environment such as heavy rain, low temperature and so on. Because the system uses optical cable as the sensing medium, it is equipped with powerful embedded intelligent algorithm to set the parameters of the surrounding environment, so that the system has the self adaptability to the changes of the external environment.

Single defense area sensitivity adjustment the sensitivity and other alarm parameters of each defense area in the system can be adjusted separately without mutual influence, so as to adapt to different surrounding environment, such as weather change, plant growth, animal activities, vehicles near the highway, etc.

The system realizes linkage alarm function in the control room, which can process the alarm information and start the linkage equipment immediately.
