Embodiment Construction

[0030] The embodiment of the present invention provides a boundary intrusion detection method to reduce the influence of climate and environmental factors on the accuracy of boundary intrusion detection. This solution is implemented based on a Doppler microwave radar sensor preset on the enclosure. The enclosure intrusion detection method includes:

[0031] Collect the I / Q channel signal generated by the Doppler microwave radar sensor according to the received reflected echo, the I channel signal is the in-phase component, and the Q channel signal is the quadrature component;

[0032] Perform intrusion analysis and processing on the collected I / Q channel signals;

[0033] According to the processing result, the warning information is sent to the terminal server, and the warning information is used to instruct the terminal server to alarm or eliminate the alarm.

[0034] In the technical solution provided by the embodiment of the present invention, a Doppler microwave radar sensor is a...

Abstract

The invention discloses a perimeter intrusion detection method, device and system. The Doppler microwave radar sensor is set on the enclosure in advance, the method includes: collecting the I / Q channel signal generated by the Doppler microwave radar sensor according to the received reflection echo, the I channel signal is an in-phase component, and the Q channel signal It is an orthogonal component; the collected I / Q channel signal is analyzed and processed for intrusion; according to the processing result, a warning message is sent to the terminal server, and the warning message is used to instruct the terminal server to alarm or eliminate the alarm. In this scheme, the electromagnetic waves emitted by the Doppler microwave radar sensor are used for intrusion detection. Since the electromagnetic waves are less disturbed by climate and environmental factors, the impact of climate and environmental factors on the detection accuracy of enclosure intrusions can be effectively reduced.

Description

Technical field [0001] The present invention relates to the field of security monitoring, and in particular to a method, device and system for detecting border intrusion. Background technique [0002] With the improvement of people's safety awareness, the application fields of safety protection products have gradually moved from government departments and large enterprises to communities and families. Among them, fence intrusion detection is an important part of the field of security protection. The fence intrusion detection refers to detecting the sky above the current protective fence, such as brick walls and fences. By using the perimeter intrusion detection product, it can detect whether there are objects passing by or illegal intruders over the perimeter, so that appropriate measures can be taken based on the detection results to achieve the purpose of security protection in the perimeter. [0003] An existing detection method for border intrusion is: intelligent video analys...
