RADIO-SEARCH SYSTEM FOR INTERCEPTING HI-JACKED VEHICLES Russian patent published in 2005 - IPC

FIELD: transport engineering; security systems.

SUBSTANCE: proposed invention relates to security systems providing search, detection and finding of current location of vehicle and possibility of interception of hi-jacked vehicles security hazard express vehicle. Subscriber's complex with receiver installed on vehicle is connected by radio with mobile communication network, microcontroller connected to alarm units and actuating devices, satellite navigation unit and subscriber's signaling device radiating code messages on carrier frequency in form of hopping-signal with information of category of message and codes of identification symbols of vehicle. Retransmission network receives code messages from subscriber's signaling devices and transmits them to security hazard express vehicle furnished with radio-search complexes. Each of said complexes contains communication and data transmission unit connected to mobile communication network, unit to store information from external sources, unit to receiver code messages from retransmission network or subscriber's signaling devices, processing, displaying and coordinate finding unit, operator's personal computer, satellite navigation unit and electronic magnetic compass.

EFFECT: improved accuracy of determination of relative location of hi-jacked vehicle and security hazard express vehicle taking part in interception.
