Core functions of the all-optical perimeter monitoring and warning system

1. Long-distance intrusion monitoring

The entire process along the optical fiber laying area is monitored in real time at any point around the clock without interruption.

2. intrusion locating

When detecting the threat of intrusion, the system can locate the intrusion occurrence point in real time based on optical signal modulation analysis, so that security personnel can take effective measures in a timely and clear manner, stop subsequent intrusion events.

3. Pattern Recognition

Identifies non-harmful environmental interference such as thunder, firecrackers, automobile sounds, and rain, and makes harmless judgments. It can also identify intrusions such as walking, crawling, touch, and mining and trigger alarms.

4. Voice listening for important parts

For high-risk areas, the system supports voice Monitoring and recording. This function can be achieved with only optical fiber without using electric or metal sensors. It enriches the functions and protection levels of the monitoring system with a single optical fiber.

5. Linkage with sound/Optical alarms of other monitoring systems

System Structure of Full-fiber perimeter monitoring and warning system

The full-fiber perimeter monitoring and warning system consists of the monitor, main controller, guide optical cable, sensor optical cable, and external components. The system monitor and controller are located in the central monitoring room. The Guiding Optical Cable, sensor optical cable, and external components are installed outdoors. You can set the control center as needed, as shown in ).

Typical application of Full-fiber perimeter monitoring and warning system

The system can use different cable laying methods based on different needs in various perimeter: concealed burial, fencing, and wall laying, and explicit and concealed laying.

1. Long-distance border Alert System

Important border lines, bonded area isolation belts, customs ports, and other long-distance and large-range anti-intrusion or cross-border places, especially in chongshan junling, desert wilderness, and manual patrol inspection are not easy to lay Optical Fiber corns.

2. Perimeter security defense for important facilities

Military locations and defense facilities: such as troops, airports, military ports, missile/rocket launch bases, radars, and communication sites;

Important national economic facilities: power stations, substations, Wenbo pavilions, financial warehouses, and stadiums;

Defense of inflammable and explosive places: oil depots, gas depots, Oil and Gas Storage Tank areas, and explosives depots;

Important defense sites: prisons, schools, reservoirs, industrial plants and mines, and important residential areas.

3. Protection against excavation, theft, and destruction of oil and gas pipelines)

4. Protection of Communication Power Cables

The perimeter security protection system based on optical fiber sensing technology has been successfully applied in Europe and America with the continuous development of optoelectronic and optical fiber sensing technologies, it has implemented alarm functions such as mobile, vibration sensing, micro-strain detection and positioning, and has been widely used in military bases, command centers, National Defense, aerospace bases, and other places, and has been rapidly promoted to civilian use.

At present, foreign products are gradually entering China, but because these products have just been switched from military to civil use, they are expensive and cannot be effectively used in China. At the same time, for perimeter protection systems that are important to the country and important places, the operation and maintenance of their systems must be real-time and cannot be interrupted. Equipment and products that adopt foreign monopoly technologies bring a lot of inconvenience in product debugging, installation guidance, post-maintenance, and performance upgrade, and even bring potential threats to confidentiality.

Therefore, security measures in important places require both advanced equipment and confidentiality to ensure that the monitoring technology used is original and unique, this satisfies the needs of China's current security technology defense system for developing proprietary intellectual property rights, advanced international standards, and unique technical performance that can improve China's perimeter defense technology level. the Intelligent Optical Fiber security defense system puts forward urgent demands.

The wide-fiber perimeter intrusion warning product is widely used in China. The wide-fiber perimeter monitoring and warning system will usher in a broader development space.
