Enclosure protection system

Abstract

The invention discloses an enclosure protection system which comprises an enclosing and protecting unit and an invading monitoring unit, wherein the enclosing and protecting unit comprises a fence or a barrier which is arranged at the periphery of the area to be protected, and the invading monitoring unit comprises a passive optical fiber which is arranged on the enclosing and protecting unit in the circumference direction and/or is buried under the ground at the outer periphery of the enclosing and protecting unit. According to the design, the passive optical fiber is applied to monitor the outside invasion, and invasion mode and position are recognized to conduct systematic warning and real time alarm. Through the monitoring mode of the passive optical fiber, higher accuracy can be achieved in the large monitoring area or the long liner monitoring area, the optical fiber is excellent in environment resistance, monitoring accuracy is not affected by stormy weather and other severe environments, even cut off by an invader, the system is still capable of continuously providing effective alarm ability and will not fall into a paralyzed state, an external power, a repeater, a signal processor and other devices are not needed, and construction and maintenance are convenient and fast.

Description

technical field [0001] The invention relates to a perimeter protection system. Background technique [0002] The existing fence protection system generally includes a fence or fence unit and an intrusion monitoring unit. The intrusion monitoring unit is used to monitor whether there are intruders or damage in the surrounding area. Or vibration sensors, although they can achieve simple defense functions, there are some disadvantages. For infrared sensors, the infrared beams are arranged to delineate the perimeter to be monitored. Whenever someone passes through the perimeter, the infrared beams are triggered. The temporary interruption of the system will start the alarm signal. The false alarm rate of this system is high. Plant leaves and small animals will cause infrared alarms, and there is no function to block the intrusion of personnel. For the electronic pulse rope, the electronic pulse rope is used to delineate the perimeter to be monitored. The electronic pulse scans ...
