The application discloses a
nuclear power KRTN16 channel in-situ processor hardware integrated
system and a hot switching method, which comprises a total power supply, a main power supply, a
backup power supply, a normal channel switch, a
backup channel switch, a switching
execution unit, a switching
control unit, a mainboard card and a
backup board card. The total power supply is connected with the input end of the normal channel switch and the input end of the backup channel switch. The main power supply is connected with the output end of the normal channel switch and the input end of the mainboard card. The
control signal output end of the mainboard card and the
control signal output end of the backup board card are connected with the input end of the switching
control unit. The output end of the switching
control unit is connected with the input end of the switching
execution unit. The output end of the switching
execution unit is connected with the execution
signal input end of the normal channel switch and the execution
signal input end of the backup channel switch. The output end of the backup channel switch is connected with the input end of the backup board card through the backup power supply. The application can realize hot switching quickly.
