Abstract
PURPOSE: To prevent the system-down for the fault of a substation, by providing an OR gate, through which the signal from the preceding station passes to the succeeding station, in each substation.
CONSTITUTION: Receiving data from a transmission line 40a is not only transmitted to a transmission line 40b through an OR gate 52 but also converted to parallel data by an P-S converter 48 and is taken into a terminal IN1 of a microprocessor 60. Serial data from a P-S converter 62 is transmitted to the transmission line 40b through the OR gate 52 also. Consequently, even if the microprocessor 60 is faulty, data from the transmission line 40a is transmitted to the transmission line 40b through the OR gate 52, and other stations transmit data normally. Since the same data as that on the transmission line 40a comes to a transmission line 42a, a transmission error is detected by checking the coincidence or the dissidence between both data.
