METHOD FOR PREVENTING UNAUTHORISED ACCESS TO FACILITIES UNDER PROTECTION Russian patent published in 2022 - IPC G08B13/19 

FIELD: signalling.

SUBSTANCE: invention relates to the field of security alarms. The technical result of the claimed technical solution is achieved by placing vibroseis and acoustic sensors on the inside of the facilities under protection directly on the entrance engineering structures and locking equipment thereof, pre-recording the background characteristics of vibroseis and acoustic effects thereon, and using the corresponding dependence pre-stored in the memory of the controllers, forming basic images of the facilities under protection based on the background characteristics of the signals; recording the changes in signals on the entrance engineering structures in case of attempts of unauthorised access to the facilities under protection, and based on the characteristics of signals, on the basis of the basic images of the facilities under protection, selecting signals and determining the degree of threat.

EFFECT: provided possibility of preventing unauthorised access to facilities under protection through entrance engineering structures.
