Abstract
PURPOSE:To reduce the effect caused by the fault of the circuit, by connecting in links between the master station and plural slave stations with a circuit and then connecting the matching impedance to the slave station near the faulty area by the command given from the master station when the fault occurs to the circuit. CONSTITUTION:A link-type connecting is given between master station 31 and slave stations 321, 322...32N with circuit 33. And input Z to be matched with the characteristic impedance Z of the circuit is secured for terminal slave station 32N, and input Z higher than characteristic Z is secured for other slave stations. Receiving circuit 34i of slave station 32i (i=1,2...N-1) possesses the function to receive the connection command and the connection cancel command sent from master station 31 and then open and close switch 35i in addition to the normal signal receiving function. When the master station detects the circuit disconnection during the fault of the circuit, the master station closes switch 35i successively in the order of the slave stations nearer the naster station. Then matching Z36i equal to characteristic Z of circuit 33 is connected and then cancelled, and finally matching Z is connected to the slave station near the faulty area. In such way, the reception unsteady state caused by the reflected wave at the position near the faulty area of the circuit can be avoided.
