MULTICHANNEL SEISMIC DEVICE OF DETECTION AND CLASSIFICATION OF INTRUDERS Russian patent published in 2016 - IPC G08B21/22 G01V1/00 G01S3/80 

FIELD: safety systems.

SUBSTANCE: invention relates to facilities for detection of a person, determination of his location in the controlled area by seismic vibrations created by him. Technical result consists in that proposed device allows with the probability of 0.97 at the confidence probability of 0.8 to detect an object and with the probability of 0.85 to classify an intruder in controlled area within the radius of 25 m. Experimental studies have shown, that the disclosed device enables to determine the location of a person with accuracy of up to 1 metre range and up to 3 degrees in direction, as well as to determine the direction of his motion. Novelty is the introduction of Q seismic receivers 1, J detectors 2 of an intruder, control 3 panel, classification 8 unit, seismic receiver monitoring 9 device, delays 10 measurer, memory 12 of calculating position device data, device 13 for measuring the location, first transceiver 14, control 15 device by an intruder detector, second transceiver 16, control panel 19 control members, decision-maker device 26 with corresponding links.

EFFECT: increase in probability of an object detection and possibility of classification of an intruder in controlled area within the radius of 25 m.
