Distributed vibration optical fiber system, as an innovative technology in the field of modern security, with its unique distributed perception ability and high-precision positioning characteristics, is gradually becoming an important choice in many fields such as perimeter security, oil and gas pipeline monitoring, and smart grid.
The system is based on optical fiber sensing technology, using ordinary multi-core optical cables as sensors to realize real-time monitoring of the perimeter or pipeline by sensing vibration signals generated by the outside world. Compared with traditional point sensors, the distributed vibration fiber optic system has higher sensitivity and longer monitoring distance, which can achieve continuous monitoring without dead angles in the true sense.
In a distributed vibrating fiber optic system, the fiber optic cable is laid in the area that needs to be monitored, and once an intruder or abnormal event occurs, the generated vibration signal will propagate along the fiber optic cable and be captured by the system. Through the analysis and processing of vibration signals, the system can accurately locate the location of the intrusion point and send out an alarm signal. This technology, with a positioning accuracy of up to 2 meters, makes the system extremely useful in the field of perimeter security.
In addition to high sensitivity and high-precision positioning, the distributed vibrating optical fiber system also has the advantages of anti-electromagnetic interference, good concealment, and intrinsic safety. It is not subject to the interference of external environments such as lightning and electromagnetic fields, and can work stably under harsh climatic conditions. At the same time, because the fiber optic cable itself is as thin as a hair, soft and easy to bend, it makes the system more convenient in the installation and maintenance process.
In terms of application fields, distributed vibration optical fiber systems are widely used in long-distance perimeter security, oil and gas pipeline safety monitoring, smart grid, railway safety monitoring and other fields. In oil and gas pipeline monitoring, the system can monitor the vibration along the pipeline in real time, and timely detect and warn possible abnormal events such as leakage, punching and oil theft, so as to ensure the safe operation of the pipeline. In smart grids, systems can be used to monitor the vibration of transmission lines and prevent line failures caused by external forces or natural disasters.
In addition, the distributed vibrating optical fiber system also has a high level of scalability and intelligence. The system can be flexibly configured and expanded according to actual needs to meet the needs of users of different scales and needs. At the same time, by introducing advanced signal processing algorithms and artificial intelligence technology, the system can realize the intelligent identification and analysis of vibration signals, and further improve the accuracy and reliability of alarms.
