Optical fiber vibration-based railway perimeter protection method

Abstract

The invention provides an optical fiber vibration-based railway perimeter protection method. The method comprises the following steps that: a railway perimeter protection system is set, wherein the protection system includes defense area induction modules, defense area data acquisition units, an information processing host and a railway administration monitoring platform; induction head end modules and induction tail end modules are distributed at defense areas of railway perimeter along a railway, each defense area induction module forms a defense area; each defense area data acquisition unit acquires intrusion vibration signals of the plurality of defense area induction modules; the information processing host receives the intrusion vibration signals of the defense area data acquisition units and identifies the intrusion vibration signals, and distinguishes abnormal data and transmits the abnormal data in a packeted manner; and the railway administration monitoring platform is used for receiving the alarm data of the information processing host and notifying responsible personnel of the alarm data.

Description

technical field [0001] The invention relates to the field of railway safety protection, in particular to a railway perimeter protection method based on vibrating optical fibers. Background technique [0002] With the development of social economy in recent years, factors of social instability and social conflicts are on the rise, and the political pressure to maintain local social stability is increasing. Especially under the instigation and instigation of foreign extremist forces, domestic saboteurs have frequently committed violent activities against the masses and sensitive areas, and the form of anti-terrorism has become more and more intense. When railways, especially high-speed railways, are damaged, it is easy to cause a large number of casualties and heavy property losses. Since the beginning of this year, two sabotage cases such as "6.25" have occurred in succession against the Wuhan-Guangzhou high-speed railway. The high-speed railway has become a new target for vi...
