FIELD: physics, communications.
SUBSTANCE: invention deals with a serial data bus containing an electric signal transfer line and is of relevance for mobile systems providing for exchange of messages between master subscribers. Serial data bus contains a data transfer line for transfer of electric signals represented by bit statuses of multiple subscribers capable of acting in the master subscriber capacity, event-driven exchange of messages between them carried out by way of broadcast addressing via the data transfer lines with at least two subscribers having transmitting-and-receiving heads inductively connected to the data transfer lines which enables noncontact takeoff of electric signal from the data transfer lines and equally noncontact transmission of the signals referred to into the data transfer lines, and an amplifier that receives the electric signals to have been transmitted into the data transfer line via inductive connection by at least two subscribers and re-transmits the signals having undergone amplification into the data transfer line.
EFFECT: operational reliability improvement.
