Abstract

PURPOSE:To realize the data communication system in which the simultaneous transmission (collision of communication) is independently detected by each transmission station, in the communication system of contention system having commonly the resource for transmission line. CONSTITUTION:The characteristic impedance of the transmission cable is 2Ra, which is one side of the bridge circuit in the trnasmission and reception stations 11,12.... In the station 11, since no balance is made to the bridge circuit for the transmitter 14 in other station and the receiver 15 of the station, the transmission signal from the transmitter 14 of other station is received without being weakened. On the other hand, the transmission signal from the transmitter 13 of the station is fed to the receiver 15 after being attenuated with the bridge circuit. The detection of collision is made by receiving the signal on the cable and comparing it with the transmission signal of the station during the transmission of the station.
