Abstract
PURPOSE: To improve the reliablity of the control of proper reliability equipment with no necessary of high control reliability, and to utilize the electronic computers effectively in a system thereat the equipment different in the reliability degree of controlling is controlled by three electronic computers.
CONSTITUTION: Memories 3 in electronic computers 1aW1c provided with micro- processors 2, memories 3 and input and output circuits 4, 5 etc. are so installed as to memorize control signals for the purpose of controlling a high reliability equipment 6, and as to memorize the control signals for the purpose of controlling a proper reliablity equipment 7aW7c. The input/ output circuts 4 are connected to the high reliablity equipment 6 via change-over switches 8aW8c and a majority decision circuit 9, and the equipment 6 is controlled by a majority signal. The input/ output circuits 5 are connected to the proper reliability euqipment 7aW7c via OR circuits 10aW10c and coinciding circuits 11aW11c, and the equipment is so consitituted as to be controlled by a coincided signal of each output signals two computers.
