To provide an SEU countermeasure commanding device and an electrical apparatus for reducing power consumption.
In a figure 3(a), an SEU countermeasure commanding device compares a neutron level of which the SEU countermeasure commanding device is notified by a neutron sensor 100 with a preliminarily set level threshold D1, and when the neutron level exceeds the level threshold D1 (step S103), sets a neutron level flag to 1, and notifies an SEU countermeasure object device of the neutron level flag 1 (steps S104, 106), and when the neutron level is equal to or less than the level threshold D1 in the step S103, sets the neutron level flag to 0, and notifies the SEU countermeasure object device of the neutron level flag 0 (steps S105, 106). On the other hand, when the neutron level flag of which the SEU countermeasure object device has been notified in the step S203 is 1, the SEU countermeasure object device turns on an SEU countermeasure execution state (step S204), and when the neutron level flag is 0, turns off the SEU countermeasure execution state (step S205).
