Abstract

The method and the system can be applied for operative control and building of security warning complexes on territorially scattered objects for the exchange of information beetween a stationary relay station, a mobile operative intervention board and controlled stationary and mobile objects. By the method, the data from the controled object are coded, modulate a high frequency signal and are transmitted. They are received by at least one relay station where they are demodulated, decoded and logically processed. When satisfying the criterion for belonging of the object to the respective zone, the data are coded, modulate a high frequency signal and are transmitted to the receiver. The system contains a stationary control desk (12) and a mobile board for operative intervention (13) each of which contains a transceiver (9), coder-decoder (10) and end receiver (11) and is connected by a radio channel to a stationary relay station (14). The relay station (14) contains a transceiver (4 & 8), coder-decoder (5 & 7) and a logic element )6) and is connected to a controlled object (15) by a radio channel, including a data source (1), coder-decoder (2) and tranceiver (3).
