Patent JP-H0421233-A (JP)
Title: Bus type network system
Inventor: IMAI MITSUO
IPC: H04L12/40
Filed: 1990-05-16
Abstract: PURPOSE:To attain always stable communication by interrupting the connection of both transmission lines on the occurrence of a broken transmission line or the like or sending a signal disabling to send a signal to the faulty transmission line. CONSTITUTION:When a broken line takes place at a point 10a in the vicinity of a station 3B, a reflection signal level of a signal sent from stations 3A, 3C is high and the stations 3A, 3C are connected to a standby transmission line 20 through the changeover of switching levers 4A, 4C thereby. Simultaneously since a reflection signal level in a branched signal of directional couplers 31A, 31B reaches a reference level or over, a relay control circuit 32 discriminates the presence of a fault in the transmission line and gives a relay interrupt command signal to a repeater 30. The repeater 30 opens a switching member 38 based on the command signal to interrupt the active system transmission line 10 and the standby system transmission line 20. Thus, the station 3B detects the fault and selects the transmission system from the active system into the standby system.
