Circumference alarm system intrusion signal identification signal based on capacitance disturbance

Abstract

The invention discloses a circumference alarm system intrusion signal identification signal based on capacitance disturbance, and relates to the technology of capacitance disturbance signal processingand identification. The method comprises the following steps: firstly performing de-noising processing on an acquired capacitance disturbance signal; and then extracting a training sample feature value by using intrinsic time scale decomposition algorithm ITD and HT transform; and finally constructing a PNN probability neural network, and providing effective characteristic quantity for the PNN neural network to train, training so as to adjust parameters of the PNN probability neural network, and then providing the adjusted parameters for a probability neural network classification module to use. The method disclosed by the invention has the advantages of being high in identification precision, good in efficiency, high in sensitivity, and high in security.

Description

technical field [0001] The invention relates to capacitive disturbance signal processing and identification technology, in particular to a method for identifying capacitive disturbance enclosure intrusion signals. Background technique [0002] With the development of society, the airport perimeter alarm system is the top priority of the airport security system. "Civil Transport Airport Safety and Security Facilities" (MH / T 7003-2017) clearly stipulates that the flight area enclosures of Class I and II airports with an annual passenger throughput of more than 2 million passengers should be equipped with an enclosure alarm system and a video surveillance system. Class III airports with 500,000 to 2 million passengers should be equipped with intrusion alarm systems and video surveillance systems. The system should be able to form a complete coverage of the physical enclosure, be able to judge the intrusion behavior of the enclosure, and classify the targets. It should be able ...

AI Technical Summary

Problems solved by technology

[0004] At present, there are few studies on the capacitance disturbance perimeter alarm. The patent document CN104851226A disclosed a capacitance disturbance perimeter alarm system and alarm method on August 19, 2015. It only provides an airport coupling capacitive alarm system, which can meet the Airport intrusion detection needs, but there is still a certain rate of false alarms and false alarms, the existing system lacks the optimization of signal processing
