<p>PROBLEM TO BE SOLVED: To forcibly turn off the power source only when there is no the possibility that the stopping process of a processor is not completed when the power source is turned off. SOLUTION: When a power source controller 3 indicates the start of a power source disconnection, the processor 1 starts the stopping process by a stopping process part 12. The state of the stopping process is reported from a state information part 1A to the power source controller 3. The power source controller 3 diagnoses whether or not the stopping process is smoothly advanced by a processor diagnostic part 3B. When the stopping process is smoothly performed, the state is diagnosed repeatedly, but if abnormality occurs, a power source forcible disconnection is reported to the processor 1. The processor 1 stores its state in an external storage device 2 by a state saving part IC. The power source controller 3 forcibly disconnects the power source a specific time later.</p> |
