Abstract

PURPOSE: To prevent system down in analogue control system by effecting off-line operation if abnormal condition is detected from signal unbalance, by means of deviding the whole of control system into two groups, in which one of them being main part that is indispensable for control duty while the other being one part which can be dead during a short time of emergency, than duplexing is effected on the former, while paralleling is effected on the latter.
