Abstract

PURPOSE:To reduce a recovery time to simplify trouble maintenance by a connecting one automatic raising circuit for one-side system trouble to corresponding CPU at a trouble time. CONSTITUTION:CPU 10 and 11 are connected to automatic raising circuits 30 and 31 for one-side system trouble which output system designation signals to switch circuit 40 at the trouble time of each other. Then, double control circuit 20 includes switch control circuit 22 which sends a switching signal to circuit 40 on a basis of the output of circuit 30 or 31 and disconnects individual circuits 30 and 31 when circuit 20 is operated normally and connects only circuit 30 or 31 to CPU 10 or 11 when circuit 20 becomes faulty. As a result, in case of the trouble recovery of the double control circuit, this circuit 50 is connected to only a CPU which is in a standby state, so that the recovery time can be reduced to simplify trouble maintenance.
