METHOD FOR OPERATIONAL AND TECHNICAL PROTECTION OF BOUNDARIES OF OBJECTS AND BOUNDARIES Russian patent published in 2019 - IPC G08B13/00 G08C19/00 

FIELD: security systems.

SUBSTANCE: invention relates to telemechanics and security equipment (SE) of important objects and boundaries based on detectors, transducers or sensors using different physical principles of intruders detection. To achieve the technical result, signals generated by the detector are subjected to additional processing using adaptive nonlinear filtration (ANF) algorithms, as a result of which indirect estimates of the formation noise , which characterizes the power of the external disturbance, which is an indirect information sign of the impulse action of the intruder on the detecting element of the detector, are determined, which are used as an information feature when generating an alert signal generated in accordance with the presented logic based on comparison of the obtained estimates of the shaping noise dispersion with the selected thresholds, wherein to increase the probability of detecting an intruder from the estimated estimates of the shaping noise dispersion, different algorithms are used to compensate for interference in the generated signal, which characterizes the time variation of the shaping noise dispersion estimates.

EFFECT: high probability of detecting an intruder and reducing the probability of false triggering and generating false alarm signals.
