Abstract

PURPOSE: To obtain a reliable multisystem switching control system which is made to make a check on a change-over switch as a rationality check.
CONSTITUTION: This is composed of multiplexed central processors 1 and 2, multiplexed process input-output devices 3 and 4 corresponding to them, multiplexed control methods (control command circuits 5 and 6) operated by outputs of input-output devices 3 and 4, multiplexed change-over switches 7 and 8 provided at the output sides of methods and turned ON by turns, and system 10 controlled by outputs of switches 7 and 8. Then, multiplexed processors 1 and2, input-output devices 3 and 4, and control methods 5 and 6 at the prior stages of switches 7 and 8 are put in a run state in parallel at any time, and input-output signals of switches 7 and 8 and status signals attending on the control of controlled system 10 are all fed back. On the basis of those signals, respective central processors 1 and 2 make a check on the operation of the whole system and the operation check of switches and perform the switching control of change-over switches 7 and 8.
