される。The recovery method for a computer according to the present invention includes a main power supply that receives power from outside, an auxiliary power supply that receives power inside the system, a power supply switching function that switches between the main power supply and the auxiliary power supply, and a power supply switching function that switches between the main power supply and the auxiliary power supply. In an electronic computer system including a power supply voltage monitoring function for monitoring the power supply voltage of a power supply and the auxiliary power supply, a timer function that starts operation according to a power outage and restoration of the voltage power supply and issues an instruction after a predetermined time; It is configured to include an external storage device, a system save function that writes information on the CPU and memory of the computer system to the external storage device according to instructions from the timer function, and a system load function that reads information.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

電源切替機能７により補助電源５から主電源４へ電源を
切替え通常状態に戻る。FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. The power supply voltage monitoring function 6 detects whether a power outage has occurred by constantly monitoring whether the voltage of the main power supply 4 has dropped. If the voltage of the main power supply 4 drops here,
When the power supply voltage monitoring function 6 detects that a power outage has occurred, the power supply switching function 7 instantly switches the main power supply 4 to the auxiliary power supply 5.
At the same time, the timer function 8 counts the duration of the power outage. When the voltage of the main power supply 4 returns to a normal value before the power outage continues for a certain period of time, and the power supply voltage monitoring function 6 detects that the power outage has been restored,
The power source switching function 7 switches the power source from the auxiliary power source 5 to the main power source 4 and returns to the normal state.
しかし、補助電源５のバッテリ容量には限りがあるので

及びメモリ２内の情報を、外部記憶装置３からロードし
、システムを再起動する。However, since the battery capacity of the auxiliary power supply 5 is limited, if the duration of the power outage counted by the timer function 8 exceeds a certain period of time, the system save function 9 saves the information in the CPUI and the information in the memory 2. The information is saved in the external storage device 3, and the system is stopped. After this, the voltage of the main power supply 4 returns to the normal value, the power supply voltage monitoring function 6 detects that the power outage has been restored, and the timer function 8 counts from this point for a predetermined time (this is the time after the power outage is restored). (This is to check the stability of the main power supply.) When the system load function 10 loads the information in the CPUI and the information in the memory 2 from the external storage device 3, the system is restarted.
このようにして本実施例は、停電のあった場合これが長

いう効果がある。As explained above, the present invention uses a timer function to count the duration of a power outage, uses a system save function to save system information to an external storage device when a certain period of time is exceeded, and uses a system load function to save system information to an external storage device when the power is restored. By loading system information from an external storage device and restarting the system, there is an advantage that even if a long power outage occurs, the system can automatically resume operation.
