Abstract

PURPOSE: To ensure the accelerated switching as well as to increase the control reliability for the general reliable apparatus through automatic selection of the processor to be used to control the intermediate or low reliability apparatus by utilizing the coincident decision result of the control output of each processor.
CONSTITUTION: Decision-by-majority circuit 10 supplies the decision-by-majority signals of processor 1, 2 and 3 to high reliability apparatus 4. Coincidence deciding circuit 11 receives 1st control output 7a, 8a and 9a for apparatus 4 from processor 1, 2 and 3, and then delivers the coincidence signal via lead wire 12 in case output 7a is in agreement with the 1st control output and via wire 13 and 14 when output 8a or 9a coincides with another 1st control output respectively. Selector circuit 15 delivers the coincidence signal of two output corresponding to each other among 2nd control output 8b, 9b and 9c given from processor 1, 2 and 3 to intermediate reliability apparatus 5 when the signals are transmitted from all or two of wires 12, 13 and 14. Selector circuit 16 selects one of 3rd control output 7c, 8c and 9c and supplies it to low reliability apparatus 6 wit supply of the input signal through either two of wires 12, 13 and 14.
