VEHICLE SECURITY ANTITHEFT SYSTEM

FIELD: transport engineering. ^ SUBSTANCE: invention relates to equipment designed for preventing unauthorized use or high-jacking of vehicles. According to invention, central control unit is connected with remote reading unit, radiomodem, security alarms warning units and units to interlock functional members of vehicle. Transponder is made possibility of inductive coupling with antenna of remote reading unit. Transceiver is coupled with radiomodem and is made for radio communication with dispatcher center. System includes also series-connected heart beats reading unit, preliminary filtering and amplification unit and digital processing unit. Central control unit is provided with additional input to which output of digital processing unit is connected. Heart beats reading unit contains antenna made for remote reception of electric signals caused by human heart beating. Digital processing unit includes series-connected analog-to-digital converter whose input is input of digital processing unit, digital filtering unit and decision making unit whose output is output of digital processing unit. Decision making unit includes series-connected detector of QRS cardiogram complex whose input is input pf decision making unit and heart beats detector whose output is output of decision making unit. Invention makes it possible to state the fact of presence of criminal in vehicle interior by heart beating electric signals. Thanks to it video camera in vehicle is required, wide-band video information transmission channel can be dispensed with and possibility of transmission of information to reduce possibility of false alarm by standard radio channel used for transmission of voice and short text messages is provided. ^ EFFECT: improved reliability of protection. ^ 5 cl, 3 dwg
