Device for recognizing disturbing signal of wide-area all-fiber security system in self-adapting mode

Abstract

The invention relates to a device for recognizing a disturbing signal of a wide-area all-fiber security system in a self-adapting mode. On the basis of a distributed all-fiber reflecting interfering sensing system, according to generating mechanisms and characteristics of various disturbing signals in the surroundings, a comprehensive signal processing method which integrates spectral subtractiondenoising or wavelet domain denoising, wavelet transform emerge threshold characteristic extraction, artificial intelligence SVM (support vector machine) and the like is provided to recognize the type of the signal and recognize a dangerous event accurately in real time. The implementing process of the device for recognizing the disturbing signal of the wide-area all-fiber security system in the self-adapting mode comprises the following two aspects of: 1, denoising the signal by using a signal denoising module, detecting an end point by using an end point detecting module, extracting a characteristic value by using a characteristic extracting module, and entering an SVM recognizing module and recognizing the type and characteristics of an input signal; and 2, determining whether to display the recognized type of the input signal by a main controller. The device for recognizing the disturbing signal of the wide-area all-fiber security system in the self-adapting mode can supply accurate signal recognition for establishing perimeter safety monitoring on an important facility and region and carry out safety alert.

Description

technical field [0001] The invention relates to a pattern recognition device, in particular to a wide-area all-fiber security system disturbance signal self-adaptive pattern recognition device, which belongs to the technical field of pattern recognition. Background technique [0002] With the development of science and technology and society, the competition between various countries and regions has become more and more fierce. At the same time, various dangerous and terrorist activities have become more and more intense. Therefore, for some important facilities or areas, such as military restricted areas, high-risk restricted areas, airports, nuclear power plants, etc., highly sensitive and intelligent security monitoring systems are required to ensure the safety of these facilities or areas. At present, the technologies used for perimeter security of buildings include infrared, microwave, and traditional barbed wire grid technologies, but they all have their own fatal shor...
