Abstract
PURPOSE: To perform a relief processing by a central processing unit, which is operated normally, by interrupting a central processing unit of a queuing system to report a fault when the fault of a central processing unit of a real time processing system is found due to a time-out signal of a monitor timer provided for every central processing unit.
CONSTITUTION: Operation states of central processing unit 21 in a real time processing and queuing central processing unit 22 are checked by themselves, and in case of normal operations, central processing unit normal state line signals 311 and 312 are transmitted to fault detection unit 20 at every fixed time. These signals are accepted by input control parts 25 and 26 in unit 20, and counter reset signal 106 is given to monitor timers 27 and 28 to return the value of timers 27 and 28 to the initial value. Then, when unit 21 in the real time processing is stopped due to some fault to transmit no signal 311, timer 27 of unit 20 is counted over after a fixed time, and the fault of unit 21 itself is detected, and interrupt is caused to queuing unit 22, and warning report signal 34 is transmitted.
