principle of operation


The precise optical fiber intrusion detection system realizes the sensing and transmission of disturbance signals through a single optical cable. The light path subsystem and signal processing subsystem of the system perform vibration detection and vibration positioning functions respectively. The system adopts high-speed data acquisition and processing technology, so the signal processing subsystem can collect and locate the vibration signal point by point at high speed, so as to realize the real-time accurate positioning function of the intrusion vibration on the perimeter of the full-sensing optical cable. The alarm response time of the system is ≤2s, and the current positioning accuracy is at least 2m.



Function introduction


◆ The system can effectively provide immediate alarm and accurate positioning for intrusion or illegal entry and exit behaviors such as perimeter destruction, climbing over the perimeter, shearing the sensing optical cable, etc. The positioning accuracy is 2-10m according to the detected length;


◆ The front-end perimeter on-site sensing detection part (all outdoor parts) can work completely without electricity, without energy consumption and loss, which is intrinsically safe, does not pose any safety threat to any human and livestock, and realizes 100% safety monitoring;


◆ The system has multi-point simultaneous intrusion/destruction detection function, and multiple intrusion events (around the perimeter) occur at the same time, so the system can accurately alarm and locate each other;


◆ The system is intrinsically explosion-proof, electromagnetic insulation, high sensitivity, electromagnetic interference resistance, chemical stability and high reliability;


◆ The front-end sensing optical cable only needs to be laid directly or S-shaped on the perimeter fence/wall (one core optical fiber can realize the system function), and there is no need to separate the fortification zones along the perimeter (there is no need to install a large number of defense zone isolators/optical modules on the perimeter site to separate the defense zones, there is no need to use multi-core optical cables, and a large number of cutting, welding, etc. of optical cables). There is no need to interrupt the connection artificially, and there is no need to lay communication optical cables in the same way. The project is simple, beautiful and maintenance-free.


◆ The system has advanced pattern recognition technology based on adaptive signal processing of BRF neural network and feature vector pattern recognition algorithm, which achieves high pattern recognition accuracy and stable shielding effect against harmless disturbance intrusion, and reduces the false alarm rate of the system. Compared with various existing perimeter alarm products in China, the distributed optical fiber (precise positioning) perimeter monitoring and warning system has better false alarm control, and the system can achieve the design goal of no false alarm and low false alarm.


◆ The anti-interference ability of the system is strong, and adverse weather conditions, nearby transit trains, cars, pedestrians and other potential factors will not affect it;


◆ The system supports interconnection with various perimeter security devices, such as video linkage, and provides standard interfaces;


◆ The system has its own equipment fault detection and alarm functions;


◆ The system software has the functions of hierarchical authority management such as administrators and operators;


◆ The monitoring center can intuitively manage and view the perimeter of the unit on the computer, and the monitoring center can give the monitoring staff an intrusion warning through various alarms such as warning lights, alarm numbers and electronic maps;


◆ The system software has detailed information statistics, and supports functions such as event query and report statistics;


◆ Outdoor equipment has good waterproof, dustproof and ultraviolet protection functions;


◆ The system has long service life and is basically maintenance-free.
