Abstract

PURPOSE:To place the information processor in operation by supplying necessary information even if information on a storage device which is backed up by a battery is lost. CONSTITUTION:The storage device 3 is stored with the information required for the operation of the information processor and backed up by a battery backup part 4. A trouble detection part 9 detects the loss of the information on the storage device 3 by making a parity check on the information stored on the storage device 3 or from the battery voltage of the backup part 4 and sends the result to a communication control part 5. When the fault detection part 9 detects the information loss, the communication control part 5 sends a specific signal out to a communication line 8 and receives information from the communication line 8. The storage device 7 in a maintenance center 2 is stored with the backup information of the information stored on the storage device 3. The communication control part 6 once receiving a specific signal from the communication control part 5 through the communication line 8 reads the backup information out of the storage device 7 and sends it out to the communication control part 5.

[Example] Next, an example of the present invention will be described. Figure 1
An example of a failure handling method for an information processing device according to the present invention is shown in FIG. The storage device 3 of the information processing device 1 stores information necessary for the operation of the information processing device 1, and the storage device 3 is backed up by a battery backup unit 4. The failure detection unit 9 checks whether the information in the storage device 3 is lost by checking the parity of the information stored in the storage device 3 or by checking the battery voltage of the backup unit 4, and provides the result to the communication control unit 5. . The communication control unit 5 sends a predetermined signal to the communication line 8 when the failure detection unit 9 detects information loss, and receives information sent through the communication line 8 .
