Computers used in offices and factories are powered through uninterruptible power supplies. This uninterruptible power supply device has a built-in battery and usually supplies power to a computer from a commercial power supply, and automatically switches to battery power supply in the event of a power failure. In the event of a power failure, power supply does not stop at all.

Backup is performed. And the uninterruptible power supply
Notify nearby workers with a buzzer. Thereafter, the worker stores the data currently being processed in the magnetic storage device and performs a process of shutting down the system. Then, the power of the computer device and the uninterruptible power supply is turned off, and the process at the time of the power failure ends.

た。In the case of the above-mentioned prior art, since data is evacuated manually at the time of a power failure, for example, when a large number of computer devices are arranged in a factory, one operation is required. There was a problem that the above-mentioned work had to be performed for each stand. In addition, with the progress of FA in recent years, there are many unmanned production lines and factories, and it is extremely time-consuming for only a small number of administrators to perform data evacuation work for all computer devices during a power outage. There is also a problem that data may be lost due to the above. Also, if power is continuously supplied to the computer device by the battery of the uninterruptible power supply without performing the data evacuation work and the work of stopping the power supply of the uninterruptible power supply, the battery of the uninterruptible power supply may be completely discharged during the power outage. As a result, there is also a problem that the voltage drops and the data being processed disappears. Furthermore, even if the power failure state is released after a long battery power supply, if the power failure occurs again before the uninterruptible power supply battery is charged, the remaining battery power is low and the data evacuation work is delayed. There was a problem that the situation of the disappearance of the event occurred.
