VIBROMETRIC SYSTEM FOR MONITORING EXTENDED SECURITY BOUNDARIES Russian patent published in 2015 - IPC G08B13/00 

FIELD: physics, signalling.

SUBSTANCE: invention relates to means of detecting an intruder of extended security boundaries. The technical result is faster and more accurate determination of the area of intrusion. The system consists of a central security post and a plurality of electronic units, each connected to a group of signal processors. Each signal processor is connected to a segmented vibration-sensitive element mounted on a physical enclosure. The electronic units are connected to the central security post by a first RS-485 interface line. The signal processors are connected to corresponding electronic units by other CAN interface lines.

EFFECT: improved functional reliability of the system by improving noise-immunity and accuracy of locating the point of intrusion, as well as use the principle of digital information transmission via communication lines with fewer wires.
