Vibrating-optical-fiber-technology-based perimeter intrusion monitoring system

Abstract

The invention relates to the field of perimeter protection safety technologies, and discloses a vibrating-optical-fiber-technology-based perimeter intrusion monitoring system. The perimeter intrusion monitoring system comprises multiple protective zone processing modules and an integrated alarm platform, wherein the multiple protective zone processing modules are arranged in a protective zone, and each protective zone processing module comprises a light emission end, a light receiving end, an optical fiber loop, a comparator and an optical terminal; one end of the optical fiber loop is connected with the light emission end, the other end of the optical fiber loop, after being folded and bent, is connected with the light receiving end, an optical signal sent by the light emission end is fed back to the light receiving end along the optical fiber loop, the comparator compares whether an optical signal received by the light receiving end is consistent with the optical signal sent by the light emission end or not, and transmits an obtained result to the optical terminal, and the optical terminal converts the result, and transmits the obtained result to the integrated alarm platform by a communication optical fiber; and when receiving that the comparison results are inconsistent, the integrated alarm platform gives a prompt alarm, so that the technical problem of not high protection safety existing in perimeter protection measures in the prior art is solved, and then the security of perimeter protection is improved.

Description

technical field [0001] The invention relates to the technical field of perimeter protection and safety, in particular to a perimeter intrusion monitoring system based on vibrating optical fiber technology. Background technique [0002] At present, the passenger dedicated lines operated in China mainly rely on the cement fence installed on both sides of the line to prevent intrusion on both sides of the line. This method has passive protection. Intruders can intrude into the railway boundary by cutting off the wire thorn cage or destroying the cement fence. At the same time, when an intrusion event occurs, it is impossible to give an audible and visual alarm to the intrusion or form any deterrent. [0003] Traditional perimeter protection solutions (infrared radiation solutions, video surveillance solutions, microwave radiation solutions, leaky cable solutions, vibrating cable solutions, electronic fences, power grids, etc.) have made due contributions to social security, but...
