Abstract
PURPOSE: To improve the reliability of the system by empolying a double monitoring system in which the operating state of the other party is monitored from each electronic computor constituting the multiple system as well as the operating state is monitored by itself in performing a multiple operation.
CONSTITUTION: The side of arithmetic control part 1a is placed in all-function operation mode, and that of arithmetic control part 2a in stand-by mode. In this monitoring operation, when no response signal is sent from data link device 1i, a monitor signal is sent from data link device 2i again and if no response is made even at a prescribed frequency or if the response signal has error, the system of control part 1a is considered to be faulty and control part 1a is stopped by stopping device 2h in ordr to stop the computer of the other system. Information on the stop of control part 1a is inputted to control part 2a by annunciating device 1e that informs the other system of the stop of its own system and interrupting input device 2g. Thus, control part 2a detects the stop of control part 1a and takes charge of all functions, improving the reliability of the system.
