DATA TRANSMISSION SYSTEM

摘要

local networks for data transmission among spatially distributed stations. SUBSTANCE: system designed for data transmission among spatially distributed stations interconnected by transmission lines in any way so that maximal probability of data transmission among stations is ensured in case of transmission failure of any kind has spatially distributed stations connected via transmission lines to interface units each being connected to respective change-over device in the form of system status switch; input/output buses of interface units are connected to transmission lines; respective input of system status switch is coupled through bus with output of system status switch locking unit one of whose inputs is connected to timer output and other, to one of outputs of transmission direction analyzing unit also through bus; inputs of the latter are connected through bus to respective outputs of interface unit; other output of transmission direction analyzing unit is connected to one of timer inputs; clock signal is applied to other input of timer. EFFECT: simplified functional circuit arrangement; enhanced operating reliability. 3 dwg
