FIELD: radio engineering. ^ SUBSTANCE: invention may be used to send control and alarm signals from a control and management station to a large group of territorially distributed facilities, and also to collect information from the specified facilities for centralised management of technological processes of territorially distributed facilities (stationary and mobile ones, for instance, the ones supplying water resources to a megalopolis). Between the control and management station and territorially distributed facilities a duplex radio communication is established at two frequencies using complicated signals with a combined amplitude modulation and phase manipulation at one bearing frequency. ^ EFFECT: higher noise immunity and validity of exchanging analogue and digital information between a control and management station and territorially distributed facilities by suppression of narrowband noise. ^ 1 cl, 4 dwg |
