SIGNALLING WIRE ENTANGLEMENT Russian patent published in 2017 - IPC E04H17/04 

FIELD: physics, control and signalling.

SUBSTANCE: invention relates to detection means used for engineering protective structures, specifically for signalling wire entanglements, used for creating a secure perimeter of a protected area from unauthorised access by individuals, equipment, animals etc, and can be used in protecting local territories (enterprises, military bases or environmentally hazardous facilities, etc) and extended areas, for example state borders. The disclosed signalling wire entanglement, comprising a wire line placed along a security fence and mounted on fence posts consecutively between first and last posts, wherein a parametric measuring device is placed on one side of the wire line. The novelty lies in that at the end of the line, opposite the side where the parametric measuring device is installed, beyond the last fence post, there is a parametric transponder connected to the line, the response signal of which matches the format of the signal measured by the parametric measuring device.

EFFECT: invention eliminates the shortcomings of existing devices associated with the security function, while maintaining a simple design.
