Abstract

PURPOSE:To realize an information transmitting system which is highly resistant to the noise and also capable of transmitting a large amount of data at a low cast, by carrying out a digital transmission by the optical data bus line using the optical fiber. CONSTITUTION:The information signals sent from terminal unit groups 7 and 8 which transmit various types of detection information of the roads and others and then receive various types of control information are connected to control center 13 via the optical function device consisting of electrooptical converter 9, photoelectric converter 14, optical fiber transmission line 4, optical data bus line 12, optical multiplexer 11, optical isolator 6 and others. Then the electric signals, i.e., the detection information of each detector of groups 7 and 8, which are supplied via converter 9 are processed. And then the electric signals, i.e., the control information of each controller of groups 7 and 8 are dilivered to electrooptical converter 9c connected to the terminal of other optical data bus line 12.
