Title:
MICROWAVE INDUCTIVE DETECTION METHOD AND DEVICE FOR SECURITY PROTECTION
Document Type and Number:
WIPO Patent Application WO/2015/085486
Kind Code:
A1
Abstract:
A microwave inductive detection method and device, relating to the technical field of microwave sensor application. By means of a microwave inductive detection device, the method utilizes the Doppler effect and analyses the peak value and the frequency of a received signal so as to judge whether there is a person effecting an intrusion behaviour in a protection deployment region, and then starts an alarm action. By introducing an anti-interference judgement link to a microwave sensing detector, the method avoids frequent false reports caused by non-human body effected intrusion behaviours and thus improves the reliability of the microwave sensing detector; meanwhile, since the improvement made by the method to the prior art can be implemented by only writing a program into a single chip microcomputer without additionally needing to add hardware apparatuses, the complexity brought about by the integration of other types of sensing technologies is avoided and the cost of installation is reduced.
