FASTENING MEANS FOR DETECTING INTRUSION Russian patent published in 2015 - IPC G08B21/00 F16B31/02 G09F3/03 G08B13/06 

FIELD: physics, signalling.

SUBSTANCE: invention relates to electronic engineering, particularly to alarm systems, and is used as a device for controlling access to a facility. The fastening means has a housing which consists of two electrodes, one of which has a shaped end part for connecting to a reciprocal shaped part of the application object, separated by a dielectric insert, which form a capacitive sensitive element which is electrically connected to a power supply, an inductive communication interface coil and an electronic unit for measuring capacitance of the sensitive elements, processing and storing information, said components being located inside the housing and connected to each other, and a safety cap made of dielectric material, which is installed on the housing of the device for protecting the sensitive element from interference.

EFFECT: preventing unauthorised replacement of the fastening means with identical means and storing information on accessing attempts while reducing temperature dependence by excluding movable parts in the structure of the sensitive element.
