INFORMATION-NAVIGATION SYSTEM FOR INTERCEPTING HI-JACKED VEHICLES Russian patent published in 2005 - IPC

FIELD: transport engineering; security systems.

SUBSTANCE: invention relates to security system providing search, detection, location and interception of hi-jacked vehicles by means of direct action vehicles. Subscriber complex is mounted on vehicle under protection. Said complex includes subscriber transmit-receive module connected by radio with cellular mobile communication network, microcontroller connected with subscriber transmit-receive module and made for reception of messages from security alarm unit and transmission of orders to actuating devices of vehicle under protection to interlock the vehicle functional units and subscriber transmitter which is connected to output of microcontroller and is made for radiating coded messages on hopping carrier frequency containing information on category of message and codes of identification signs of vehicle under protection. Search complexes are installed on direct action vehicle. Each said complex contains search transmit-receive module connected to cellular mobile communication network and coded messages reception unit made for reception by radio of coded messages from subscriber transmitter on hopping carrier frequency. Moreover, each subscriber complex is furnished with satellite navigation subscriber unit whose output is connected to additional input of microcontroller. The latter is made for converting satellite navigation data into coded message format for radiating by subscriber transmitter and into coded message format for radiating by transmit-receive module. Each search complex includes data format converter unit whose first input is connected to output of coded messages reception unit and second input, to output of search transmit-receive module, and personal navigator made for reception and processing of global satellite navigation signals, determination of direction of movement and distance to chosen point of route and displaying said parameters on indicator screen. Input of personal navigator is connected to output of data format converter unit.

EFFECT: provision of concealed interception of hi-jacked vehicle using convenient personal navigation pointer-and-scale instruments widely used in practice.
