FIELD: transport engineering. ^ SUBSTANCE: invention relates to devices protecting vehicles from unauthorized use. Use is made of data processing center and subscriber's complex mounted on vehicle. Each electronic module which controls functional units of vehicle is connected by common multiplex bus with microprocessor control unit. First and second subscriber's transceivers are made for reception and transmission of signals through standard movable communication cellular network and specialized movable communication cellular network and are connected with microprocessor control unit through said networks controllers-format converters. Unit is provided to analyze intentional interferences in standard cellular network whose output is connected with microprocessor control unit. Data processing center exchangers data through standard cellular communication network with first subscriber's transceivers. In case of reception of intentional interferences from analyzer unit of standard cellular communication network, microprocessor control unit sends alarm signal by means of second subscriber's transceivers into specialized cellular communication system which interlocks functional units of vehicle. In proposed system, specialized cellular movable communication network is made in form of microcellular network for transmission of data with possibility of transmission of alarm signal from second subscriber's transceiver installed on one of vehicles in zone of its action to second subscriver's transceiver installed on other vehicle. If alarm signal is received by second subscriber's transceiver by specialized cellular communication system channel from second subscriber's transceiver installed on any other vehicle and reception of data from intentional interference analyzer unit of standard cellular communication system, stating the fact that no intentional interference are present, microprocessor control unit transmits alarm signal to data processing center through standard cellular communication network by means of first subscriber's transceiver. ^ EFFECT: simplified design of system, preservation of serviceability and functional reliability in case of intentional interferences in standard cellular communication networks. ^ 2 cl, 2 dwg |
