摘要

FIELD: radio engineering, communication.SUBSTANCE: control station for receiving and transmitting paths of a decametre-range radio communication node, comprising wire communication equipment, having L groups of inputs/outputs, wherein each group of inputs/outputs can be connected by wire links to a corresponding group of outputs/inputs of one of the NL receiving paths of the radio receiving centre or to a corresponding group of outputs/inputs of one of the N transmitting paths of the radio transmitting centre; the outputs/inputs of the wire communication equipment are connected to corresponding inputs/outputs of a control signal generator-distributor, each of the two outputs/inputs of which is connected to the input/output of the corresponding radio relay communication transceiver, the output/input of which is connected to the input/output of the corresponding radio relay communication antenna; said control station also includes a first signal converter and a second signal converter, the first and second outputs/inputs of which are connected to corresponding first and second additional inputs/outputs of the control signal generator-distributor, the third additional inputs/outputs of which are connected to corresponding outputs/inputs of the first signal converter, the inputs/outputs of which are connected to corresponding additional outputs/inputs of the wire communication equipment, the other additional outputs/inputs of which are connected to corresponding first inputs/outputs of the second signal converter, the second inputs/outputs of which are connected to corresponding additional outputs/inputs of the control signal generator-distributor.EFFECT: facilitating duplex and simplex telephone sessions between two radio communication nodes or between a radio communication node and another radio subscriber with the elimination of undesirable delays of the transmitted speech signal, which is converted to digital form when passing through two radio communication node control stations, performing, in a controlled radio communication node, on-line prediction of characteristics of ionospheric propagation of radio waves by performing vertical sounding or backscatter sounding of the ionosphere using pulsed signals, which improves the reliability of communication sessions conducted by the radio communication node, by selecting the optimum working frequency based on the results of sounding the ionosphere, performed before the beginning of each communication session without using additional equipment in the radio communication node; improved functional capabilities of the control station and high reliability of transmitting control signals between interacting composite parts of the radio communication node by backing up control channels, which in turn improves the efficiency of control and reliability of operation of the radio communication node overall.2 cl, 1 dwg
