SYSTEM FOR SEARCHING AND INTERCEPTING HIGH-JACKED VEHICLES Russian patent published in 2005 - IPC

FIELD: transport engineering; centralized radio security systems.

SUBSTANCE: vehicle is provided with carry-on security set made for receiving signals of global satellite radio navigation system and determining real-time location of high-jacked vehicle, and for transmitting and receiving signals from standard cellular mobile communication network and radiating signals with hopping carrier frequency-hopping signals with code messages containing identification signs of vehicle and its current location. Balloon subsystems are distributed within the limits of observed territory, each consisting of air observation complex connected by variable-length cable and including retransmitter of hopping signals and flight parameters check unit, and ground complex with winch for variable-length cable to supply power to balloon carrier, receive flight parameters check signals from balloon complex and control winch. Data acquisition and processing center is made for receiving retransmitted hopping signals, selection and processing of code messages and presenting results of processing in form of vehicle marks moving on street-road chart, finding real-time location of vehicle and forming and transmitting coded messages containing identification signs of vehicle and its real-time location in the street to centralized security system stations to form orders to hazard express teams and to transmit by radio, or by wire communication channels, flight parameters control commands for balloon carrier and receive flight parameters control, signals from ground complex. Air observation complex includes video camera, video camera control unit, video image compression unit and video image transmitter made for transmitting compressed video images to data acquisition and processing center by radio from balloon carrier. Said data acquisition and processing center provides geometric and amplitude transformations of video images and registration of images with corresponding fragments of street-road chart and searching and identification of vehicle by received coded messages, verification of location of vehicle relative to elements of street-road network and correction of data transmitted to centralized security system station of form order to hazard express teams.

EFFECT: improved accuracy of location of high-jacked vehicle at violation of stable reception of signals of global satellite radio navigations system.
