Perimeter Security System Of Composite Fiber Optic And High-voltage Pulse

With the rapid progress of society, and the continuous improvement of quality of life, People’s security requirements are constantly increased, and thus the perimeter intrusion alarm system to become the first line of defense for people security. The protection of the perimeter monitoring alarm system applications, mainly infrared on the radio detection systems, laser beam detection system, microwave detection system, electromagnetic leakage cable systems and electronic fence system, etc. these alarm systems currently in use have their own characteristics and use, but has its limitations, such as the installation of complex equipment concealment, false positive rate and other shortcomings. It has an outdoor passive, any address of sensing area, can field the laying of anti-electromagnetic interference, anti-lightning strike lightning, etc. In modern times, based on the monitoring of the fiber grating sensing technology, the measurement has been applied to many fields, such as coal, oil tanks, oil pipelines, bridge and other sensitive facilities. It has great significance that based on fiber Bragg grating, perimeter intrusion alarm system research and development. This article from theory, combined with the experimental fiber grating sensing technology in the fiber grating perimeter intrusion alarm system. This paper details the social power class and fiber class of anti-intrusion alarm system, to identify their strengths and weakness by analyzing research and development of a fiber grating vibration sensor-based perimeter intrusion alarm system. Effectively compensate for lack of previous anti-intrusion alarm system, implementation of all-weather, with high immunity, science addressing, outdoor passive and able to meet the requirements of the present perimeter intrusion alarm system.
