FIELD: radio engineering, communication.
SUBSTANCE: proposed downhole system of signals transmitting to transmit data along the downhole components string, containing the plurality of interconnected downhole components, contains: one or more communication lines, that carry the radio frequency signals along the string of downhole components; at least one master communication means selected from the group: the surface interface, the downhole interface and unit; and the plurality of fault-secure transponders, disposed within the drill pipe joints, spaced along the mentioned downhole component string, at that the fault-secure transponders is being susceptible to the radio frequency signals received on one or more communication lines, at that the transponders have the operating mode and the failure mode. Moreover, the mentioned at least one master communication means provide connection via one or more communication lines by modulating the data into impulses of radio-frequency energy, at that the radio frequency energy has the frequency range from 10 MHz to 3 GHz. The RF energy impulses are transmitted over one or more communication lines, available to the fault-secure transponders, so that to bypass or pass through the fault-secure transponder at least along one or more communication lines. Electronic means in the fault-secure transponder are connected to one or more communication lines in parallel with one or more RF keys to provide the fault-secure operation on communication lines. In this case, when the fault-secure transponder is in the failure mode, then the electronic means in the transponder are disconnected from the communication lines by means of the radio frequency key, which is in closed position provides a continuous passive signal path through these communication lines, and when the fault-secure transponder is in operation mode, the electronic means in the transponder are connected to the communication lines by means of the radio frequency key in the open position. The RF energy impulses, that passed or went through the fault-secure transponder, is repeatedly generated by other fault-secure transponder along the communication lines independent on the communication line, at which the impulses are detected.
EFFECT: provision of the high data rate and uninterrupted operation of the communication channel.
