COMPLEX AND SIGNALING DEVICE FOR DETECTION OF MOVABLE SECURITY OBJECTS Russian patent published in 2020 - IPC B60R25/00 G08B25/00 

FIELD: physics.

SUBSTANCE: disclosed is a system for detecting movable security objects (e.g. automobiles), comprising detection device (3), control unit (4). Detection device (3) is made in the form of a transceiver with the possibility of transmitting and receiving signals in order to detect in the zone of its operation signaling device (1) installed on a security object. Detection device (3) is also configured to receive a signal from signaling device (1) installed on security object (2), with information on the presence in the coverage area of the device of the means preventing the normal passage of the signal. Signal device (1) installed on the monitored security object (2) is made in the form of a transceiver with the possibility to interact with detection device (3), to receive signals indicating presence in the coverage area of signal device (1) of means preventing normal passage signal and transmit information on presence of said means to detection device (3). Detection device (3) is configured to receive signals indicating presence in its coverage area of means preventing normal signal passage. Signal device (1) and detection device (3) are configured to apply algorithms based on the fuzzy logic principle, which enable to overcome noise preventing the normal passage of the signal.

EFFECT: enabling transmission of an alarm signal, even if there are means in the coverage area of the signal device preventing the signal from passing normally.
