Abstract

PURPOSE:To secure a correct transmission even in case some fault may occur to the data circuit, by multiplying the alarm state display signal and the action state display signal within each subordinate station and transmitting the multiplied signals to the master station by the subordinate station and then analyzing the signals at the master station to perform a centralized monitor for the transmission network.
