Distributed Fiber Optic Pipeline Leakage Vibration Monitoring System

Characteristics of distributed fiber optic pipeline leakage vibration monitoring system:

1. The system can perform full range detection over long distances, and each fiber optic signal processor can monitor a distance of 30 kilometers.

2. The system is capable of precise vibration monitoring over long distances.

3. Good reliability and strong anti-interference ability. Due to the use of distributed fiber Raman scattering principle for detection, it is not affected by system losses caused by factors such as light source power fluctuations and fiber bending. Therefore, distributed fiber sensors have very good reliability and stability.

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

5. The leakage vibration monitoring system can record the normal operation data and accident record files, in order to improve the operating environment and prevent accidents through analysis, which traditional alarm monitoring systems cannot achieve.

6. The leakage vibration monitoring system is not affected by the environment in which the pipeline is located. Whether it is installed underground in noisy cities or industrial areas, or in quiet wilderness areas, it is not affected by external interference such as electromagnetic waves. It is corrosion-resistant and can work in harsh chemical environments.

7. The leakage vibration monitoring system uses ordinary communication optical cables, consisting of core optical fibers, which are low-cost. Compared to 1-core optical cables, it has greater advantages in intelligent analysis and false alarm prevention.

8. The system mainly includes: the pipeline fiber optic warning system is composed of fiber optic warning host, fiber optic warning terminal, on-site warning unit (substation), etc. In this system, the on-site warning unit (substation) is composed of fiber optic vibration detectors, communication optical cables, front-end and back-end optical processing modules, and auxiliary equipment. Reasonably priced, easy to install, and compatible with other security technology equipment such as video transmission systems, sound alarms, and other configurations. Damaged optical fibers only need to be fused to work normally. Optical fibers are non oxidizing, non rusting, highly flexible, corrosion-resistant, and have a service life of several decades.

Advantages of Distributed Fiber Optic Pipeline Vibration Monitoring System:

The front-end of the system does not require power supply.

The system adopts passive sensors, and the front-end of the system does not require power supply. It is suitable for places that are flammable, explosive, and inconvenient to lay power lines, as well as the perimeter of strong electromagnetic interference environments.

Reduce construction and maintenance costs.

Because there is no need to lay power signal lines at the front end of the defense zone, construction costs are reduced, and system failures caused by line aging are also avoided, reducing maintenance costs.

The detection rate is 100%.

Using optical cables as sensing units and utilizing computers to collect and identify data, achieving long-distance and large-scale detection of defense zones with a detection rate of 100%.

Avoid lightning strikes.

The front-end sensor uses vibration sensing fiber optic cables, which are not affected by electromagnetic interference or radiation, effectively avoiding damage to the system and the impact on other systems caused by lightning strikes.

Effective control of false alarm rate.

The system is embedded with intelligent algorithms that compare intrusion signals with the system's built-in signal database to analyze and determine whether they are real intrusion signals. This has made a qualitative breakthrough in solving the problem of product false alarms and can effectively block interference signals such as bird drops and tree branch shaking.

Reduce intrusion and damage.

Due to the fact that the main systems are all centralized in the control room, intrusion and damage to the main systems are avoided, greatly reducing the cost of system damage and maintenance, while also increasing the service life of the system.

Support simultaneous alarm for multiple defense zones.

This system analyzes signals independently for each defense zone and operates independently. When someone invades from different defense zones at the same time, the invaded zones can alarm simultaneously without affecting each other.(Each defense zone can set its own defense zone parameters based on the different environments it belongs to.)

Excellent material selection for front-end systems.

The relay box and terminal box, as front-end systems, are made of engineering plastic for their shells, which have the characteristics of waterproof, anti-corrosion, pressure resistant, and impact resistant.(Based on the characteristics of the laying environment, change the appearance of the equipment color, etc., for personalized design. Beautiful and concealed)

Suitable for harsh environments such as heavy rain, low temperatures, etc.

Due to the use of optical cables as sensing media and powerful embedded intelligent algorithms for parameter setting of the surrounding environment, the system has the ability to adapt to changes in the external environment.

Single zone sensitivity adjustment

The sensitivity and other alarm parameters of each defense zone in the system can be adjusted separately without affecting each other to adapt to different perimeter environments, such as weather changes, plant growth, animal activities, vehicles on nearby highways, etc.

Alarm device linkage is convenient and fast

This system implements linkage alarm function in the control room, which can process alarm information in real time and activate linkage devices.
