As shown in FIG. 6, the microcomputer 351 of the store computer 301 reads the scheduled power outage data stored in the planned power outage data file F5 at intervals of N minutes (for example, N = 1) (step S1: first data). Read means 111), the execution flag is “execution” (“0: execution”), and there is scheduled power outage data in which the start date and time of the planned power outage (rotary power outage) is set within 30 minutes from the current date and time (Yes in step S2), a warning message (a warning that a planned power outage will be executed soon) is displayed on the LCD 311 (step S3: notification means 112). Here, within 30 minutes from the current date and time is a first time during which the operation being processed and the shutdown process for the OS (Operating System) can be executed from the current date and time.

  FIG. 7 is a front view showing an example of a warning message. As shown in FIG. 7, as an example, a warning message M “There is a possibility that a power failure may occur after 30 minutes. Please close the job.” Is displayed. Note that the notification is not limited to display, but may be notification by voice or the like.

  When the warning message M is displayed on the LCD 311 in this way, the operator presses the “OK key” K displayed together with the warning message M by operating the mouse 313 or the like, and is operating by operating the mouse 313 or the like. Terminate the business.

  The microcomputer 351 of the store computer 301 has a predetermined time (e.g., a second time in which the shutdown process for the OS (Operating System) can be executed is shorter than the first time from the start of displaying the warning message M). , 20 minutes) (Yes in step S4), the display of the warning message M is terminated, and the power failure scheduled data stored in the power failure scheduled data file F5 is read again (step S5: second data reading means) 113), it is determined that there is a power outage scheduled data in which the execution flag is “executed” (“0: execution”) and the start date and time of the planned power outage (rotary power outage) is set within 10 minutes from the current date and time. If this occurs (Yes in step S6), a shutdown command is sent to the OS (Operating System) to shut down the system. (Step S7: shutdown start means 114). Here, “within 10 minutes from the current date and time” is a second time during which shutdown processing for an OS (Operating System) can be executed from the current date and time.

  In addition, when the planned power outage (rotary power outage) is canceled, the execution flag is changed to “1: not yet executed”, so the microcomputer 351 of the store computer 301 has the execution flag “ 1: “Not implemented” (No in step S2), display of the warning message M and shutdown processing are not performed.

  In addition, the planned power outage (rotary power outage) is scheduled to be implemented at the beginning, and the execution flag is implemented ("0: Implemented") in step S1, and the planned power outage (rotary power outage within 30 minutes from the current date and time) ) If the power outage scheduled data determined to have a start date / time set is canceled just before implementation, the implementation flag of the power outage scheduled data is changed to “1: Not implemented”. Therefore (No in step S6), the process returns to step S1 without performing the shutdown process in step S7.

  In this embodiment, the display start time (first time) of the warning message M is 30 minutes before the start date and time of the planned power failure (rotary power failure), and the time until the shutdown start (second time) is the planned power failure. Although it is 10 minutes before the start date of (rotary power failure), the present invention is not limited to this, and the display start time (first time) of the warning message M and the time until the shutdown start (second time) are appropriately set. Can be changed.

  As described above, according to the present embodiment, the planned power outage (rotary power outage) is performed within the first time when the operation being processed and the shutdown processing for the OS can be executed from the current date and time. When the warning message is displayed and the warning is given, the operator can take sufficient time to finish the operation being processed, and the OS shutdown process is performed shorter than the first time from the start of warning notification. After the elapse of a predetermined time that can secure the second time that can be executed, a shutdown command is sent to the OS within the second time during which the shutdown process for the OS can be executed from the current date and time. By starting the shutdown, the database can be saved and the OS can be shut down sufficiently. Conductive even when the (rotation outages) is performed, it is possible to complete reliably operator operation, it is possible to reliably prevent a hard failure, the DB failure or the like.
