In other words, each device is equipped with a power supply that exceeds the power capacity required by the device itself. At this time, normally, the redundant power supply is configured to include a plurality of AD / DC conversion devices, and is configured by adding one redundant power supply device. The apparatus must be equipped with a power supply having an excessive power supply capacity, and as described above, there are problems of increased cost and increased power consumption.

  A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a block diagram illustrating a configuration of the entire information processing system including a plurality of devices according to the present embodiment, and FIGS. 2 to 3 are functional block diagrams illustrating a configuration of each device. 4 to 6 are a flowchart and a sequence diagram showing an operation during power control in the information processing system.

[Constitution]
As shown in FIG. 1, the information processing system according to the present embodiment includes three devices A, B, and C (component devices and electronic devices), and each device A, B, and C is a computer. And its peripheral devices. The information processing system operates based on the functions of the devices A, B, and C, and also operates as a power supply control system to control the power sources of the devices A, B, and C.

  Each of the devices A, B, and C includes service processors 1, 4, and 6 that are control devices (control means) that control the operation and power supply status of the devices themselves, and power supply devices 2, 5, and 7, respectively. ing. In particular, the device A is equipped with a redundant power supply device 3 in addition to the power supply device 2, and is connected to the power supply device 2 via the power supply bus 100. The power supply device 2 of the device A and the power supply device 5 of the device B are connected by a power supply bus 101, and the power supply device 5 of the device B and the power supply device 7 of the device C are connected by a power supply bus 102. Further, the service processor 1 of the device A and the service processor 4 of the device B are connected by a signal line 201, and the service processor 4 of the device B and the service processor 6 of the device C are connected by a signal line 202. As a result, as will be described later, the service processors 1, 4 and 6 of the devices A, B and C are connected to each other, and data communication can be performed between the service processors 1, 4 and 6. Further, the redundant power supply device 3 provided in the device A is connected to the power supply devices 2, 5, and 7 provided in the devices A, B, and C, and the device A and the other device B are connected. , C can be incorporated into each of the devices A, B, C. Hereinafter, each of the devices A, B, and C will be described in detail.

  FIG. 2 shows a configuration of the device A. As shown in this figure, in the service processor 1 of the apparatus A, a predetermined program is incorporated, so that an abnormality detection processing unit 11, a power supply built-in control processing unit 12, a number management processing unit 13, and a number information The storage unit 14 is constructed. The power supply device 2 includes four AC / DC conversion devices 21, 22, 23, and 24, and all the AC / DC conversion devices are used when the device A operates. The redundant power supply 3 is composed of four AC / DC converters 31, 32, 33, and 34. When the devices A, B, and C are operating normally, they are on standby (not used). It is in a state. Note that the number of AC / DC converters constituting the power supply device 2 and the redundant power supply device 3 is not limited to that described above.

  And the said abnormality detection process part 11 (abnormality detection means) monitored the state of the power supply device 2 with which the apparatus A which is itself was equipped, and abnormality, such as a failure, generate | occur | produced in the AC / DC converters 21-24 Is detected. Then, the AC / DC converter in which an abnormality has occurred is specified, and this is notified to the power supply built-in control processing unit 12.

  When receiving a notification that an abnormality has occurred in the power supply device 2, the power supply incorporation control processing unit 12 (power supply incorporation means) first reads the number information stored in the number information storage unit 14. This number information is information representing the number of AC / DC converters 31 to 34 of the redundant power supply 3 that are not used (standby) and are incorporated in the devices A, B, and C and are not used as redundant power supplies. It is. For example, in the initial state, since none of the AC / DC converters 31 to 34 of the redundant power supply device 3 is used, “4” is stored as the number information. When the read unit number information is “0”, the power supply built-in control processing unit 12 is a device equipped with the AC / DC converter in which an abnormality has occurred, in this case, the device A that is itself. Is issued to stop the device A.

  Further, the power supply built-in control processing unit 12 reads the number information, and if the number information is not “0”, unused AC / DC converters 31 to 34 that can be used as redundant power sources remain. Therefore, instead of the AC / DC converters 21 to 24 in which an abnormality has occurred, the power supply bus 100 is set so that one of the AC / DC converters 31 to 34 in the redundant power supply device 3 functions in the device A. Incorporate through. Thereby, the power supply of apparatus A can be restored and normal operation can be continued. At this time, since the power supply built-in control processing unit 12 uses one of the AC / DC conversion devices of the redundant power supply device 3, the power management control processing unit 12 notifies the number management processing unit 13 to that effect.

  The power supply built-in control processing unit 12 causes an abnormality in the AC / DC converters (for example, reference numerals 51 to 54) of the other devices B and C that are not equipped with the redundant power supply device 3, and the other devices B and C When there is a request for incorporation of a redundant power supply, the other devices B and C are controlled to incorporate one of the AC / DC power supply devices of the redundant power supply device 3 through the power supply buses 101 and 102.

  When the number management processing unit 13 (conversion device number management means) receives a notification using one of the AC / DC conversion devices of the redundant power supply device 3 from the power supply built-in control processing unit 12, the number management processing unit 13 stores it in the number information storage unit 14. The number information being updated is reduced by 1 and stored. For example, as described above, when one of the four AC / DC converters is incorporated in the device A, “4-1 = 3” and “3” is updated and stored as the number information. The number management processing unit 13 has a function of notifying the updated number information to the other apparatuses B and C when the number information is updated. Further, the number management processing unit 13 may receive a notification of updating the number information from the number management processing unit 43 or the like of another device B or C. In this case, the number management processing unit 13 is already stored in the number information storage unit 14. The updated number information is stored in the notified new number information. By having the above-described function, the number information of the same value is held in all apparatuses A, B, and C.

  Next, the configuration of the apparatuses B and C will be described. Since the devices B and C have almost the same configuration, the configuration of only the device B will be described with reference to FIG.

  As shown in FIG. 3, the device B has substantially the same configuration as the device A described above, and is different in that the redundant power supply device 3 is not installed. Then, by incorporating a predetermined program into the service processor 4 of the device B, an abnormality detection processing unit 41, a power supply incorporation control processing unit 42, a number management processing unit 43, a number information storage unit 44, Has been built. The power supply device 5 includes four AC / DC conversion devices 51, 52, 53, and 54, and all the AC / DC conversion devices are used when the device B operates. Note that the number of AC / DC converters constituting the power supply device 5 is not limited to that described above.

  Then, the abnormality detection processing unit 41 (abnormality detection means) monitors the state of the power supply device 5 installed in the device B that is itself, and the AC / DC conversion devices 51 to 54 that constitute the power supply device 5 fail. Detect that an abnormality such as Then, the AC / DC converter in which an abnormality has occurred is specified, and this is notified to the power supply built-in control processing unit 42.

  When receiving a notification that an abnormality has occurred in the power supply device 5, the power supply incorporation control processing unit 42 (power supply incorporation means) first reads the number information stored in the number information storage unit 44. This number information is in an unused (standby) state that is incorporated in the devices A, B, and C and is not used as a redundant power source among the AC / DC conversion devices 31 to 34 of the redundant power supply device 3 of the device A described above. This is information representing the number of objects, and has the same value in all apparatuses A, B, and C as described above. When the read number information is “0”, the power supply built-in control processing unit 42 is a device equipped with the AC / DC conversion device in which an abnormality has occurred, in this case, the device B that is itself. Is issued to stop the apparatus B.

  Further, the power supply built-in control processing unit 42 reads the number information, and if the number information is not “0”, an unused AC / DC converter that can be used as a redundant power supply is included in the redundant power supply 3. Since it can be determined that the remaining AC / DC converters 51 to 54 in which an abnormality has occurred, one of the AC / DC converters 31 to 34 in the redundant power supply device 3 of the device A functions as the device B. Then, control is performed so as to be incorporated into the apparatus B via the power supply buses 100 and 101. For example, the device A is requested to incorporate the AC / DC conversion device of the redundant power supply device 3, and in response to this, the service processor 1 of the device A uses the device B of the AC / DC conversion device of the redundant power supply device 3. Embedded processing for is executed. Thereby, instead of the AC / DC converters 51 to 54 in which an abnormality has occurred in the device B, one of the AC / DC converters of the redundant power supply device 3 is incorporated in the device B, and the power supply of the device B is restored. Normal operation can be continued. At this time, since the power supply built-in control processing unit 42 uses one of the AC / DC conversion devices of the redundant power supply device 3, the power supply control processing unit 42 notifies the number management processing unit 43 to that effect.

  When the number management processing unit 43 (conversion device number management means) receives a notification using one of the AC / DC conversion devices of the redundant power supply device 3 from the power supply built-in control processing unit 42, the number management processing unit 43 stores it in the number information storage unit 44. The number information being updated is reduced by 1 and stored. The number management processing unit 43 has a function of notifying the updated number information to the other apparatuses A and C when the number information is updated due to an abnormality in the apparatus B. Further, the number management processing unit 43 of another device A or C may receive a notification of updating the number information. At this time, the number management processing unit 43 may receive the number information already stored in the number information storage unit 44. Is updated and stored in the new number information received.

[Operation]
Next, operation during power control in the system having the above configuration will be described with reference to FIGS. FIG. 4 shows the operation at the time of power control in one device (reference numerals A, B, C), and FIGS. 5 to 6 show the operation at the time of power control in the entire system. In particular, FIG. 5 shows an operation when a power supply abnormality occurs in apparatus A, and FIG. 6 shows an operation when a power supply abnormality occurs in apparatus B.

  First, with reference to FIG. 4 to FIG. 5, an operation when a power supply abnormality occurs in the device A will be described. Here, FIG. 4 shows the operation of the device A.

  First, in the device A, the number information storage unit 14 stores in advance the number information “4” indicating the unused number of AC / DC converters constituting the redundant power supply device 3. The number information is notified from the device A to the devices B and C, and the number information “4” is stored in the number information storage unit 44 in the devices B and C.

  When the power source of the device A is turned on, the AC / DC conversion devices 21 to 24 of the power supply device 2 are used and are in an operating state, and the AC / DC conversion devices 21 to 24 constituting the power supply device 2 are always in operation. Whether or not an abnormality such as a failure has occurred is monitored (step S1 in FIG. 4). Similarly, the other devices B and C also monitor whether or not an abnormality such as a failure has occurred in the AC / DC converters constituting the power supply devices 5 and 7 provided in the devices B and C, respectively. Here, in the device A, when a failure occurs in one AC / DC conversion device (for example, one indicated by reference numeral 21) and an abnormality is detected (Yes in step S2 in FIG. 4, step S11 in FIG. 5, abnormality). Detection step), the number information n indicating the number of unused AC / DC converters of the redundant power supply device 3 is read from the number information storage unit 14 to check whether or not the number information n = 0 (step S3 in FIG. 4). Step S12 in FIG. Since the number n of unused AC / DC converters is “4” (No in step S3 in FIG. 4), one of the AC / DC converters 31 to 34 of the redundant power supply 3 (for example, (Indicated by reference numeral 31) is incorporated in place of the AC / DC converter 21 in which the abnormality of the power supply device 2 has occurred (step S4 in FIG. 4, step S13 in FIG. 5, power supply incorporation step). Thereby, the AC / DC conversion device 31 of the redundant power supply device 3 is incorporated into the power supply device 2 via the power supply bus 100, and the operation of the device A is continued.

  At this time, since the device A uses one (reference numeral 31) of the AC / DC converters of the redundant power supply 3, the remaining three AC / DC converters (reference numerals 32, 33, and 34) remain. The number information n is reduced by 1 (step S5 in FIG. 4), and the number information n = “3” is updated and stored in the number information storage unit 14 with “4-1 = 3” (step S6 in FIG. 4, FIG. 4). 5 step S14, conversion device number management step). The device A notifies the updated number information n to the other devices B and C via the signal lines 201 and 202 (step S7 in FIG. 4 and step S15 in FIG. 5). Then, the devices B and C that have received the notification of the updated number information n update and store the notified number information n = “3” in their own number information storage unit 44 or the like (step of FIG. 5). S16, S17). As a result, all the devices A, B, and C are stored in a state in which the unused number (n = 3) of the AC / DC conversion devices of the redundant power supply device 3 is matched.

  Next, a case where an abnormality has occurred in the power supply device 5 of the device B will be described with reference to FIGS. Here, FIG. 4 shows the operation of the apparatus B.

  First, all the devices A, B, and C are in a state where they are monitored for abnormality such as a failure in the AC / DC converters constituting their own power supply devices 2, 5, and 7 (FIG. 4 step S1). Here, in the device B, when a failure occurs in one AC / DC conversion device (for example, one indicated by reference numeral 51) and an abnormality is detected in the service processor 4 of the device B (Yes in step S2 in FIG. 4). , Step S21 in FIG. 6, abnormality detection step), the number information n indicating the number of unused AC / DC converters of the redundant power supply device 3 installed in the device A is read from the number information storage unit 44, and the number information n Whether or not = 0 is checked (step S3 in FIG. 4 and step S22 in FIG. 6). Since the number n of unused AC / DC converters is “3” (No in step S3 in FIG. 4), one of the AC / DC converters 32 to 34 of the redundant power supply 3 (for example, (Indicated by reference numeral 32) is incorporated in place of the AC / DC converter 51 in which the abnormality of the power supply device 5 has occurred (step S4 in FIG. 4, power supply incorporation step). At this time, for example, the device B issues a request for incorporating the redundant power supply device 3 to the device A (step S23 in FIG. 6), and in response to this, the device A responds to one of the redundant power supply devices 3 (reference numeral 32). ) Is incorporated into the apparatus B (step S24 in FIG. 6). As a result, the AC / DC conversion device 32 of the redundant power supply device 3 of the device A is incorporated into the power supply device 5 of the device B via the power supply buses 100 and 101, and the operation of the device B is continued.

  At this time, since one of the AC / DC converters (reference numeral 32) of the redundant power supply device 3 is used, the remaining two AC / DC converters (reference numerals 33 and 34) remain. Accordingly, the device B reduces the number information by 1 (step S5 in FIG. 4), updates the number information n = “2” to “3-1 = 2” and stores it in the number information storage unit 44 (FIG. 4). Step S6, Step S25 of FIG. 6, conversion device number management step). Then, the device B notifies the updated number information n to the other devices A and C via the signal lines 201 and 202 (step S7 in FIG. 4 and step S26 in FIG. 6). Then, the devices A and C that have received the notification of the updated number information n update and store the notified number information n = “2” in their own number information storage unit 14 or the like (step of FIG. 6). S27, S28). As a result, all the devices A, B, and C store the unused number (n = 2) of the AC / DC converters of the redundant power supply device 3 in a matched state.

  After that, if an abnormality occurs in any of the devices A, B, and C in the AC / DC converters constituting the power supply devices 2, 5, and 7, the AC / DC converters in which an abnormality has occurred are replaced as described above. The AC / DC converter of the redundant power supply device 3 is incorporated, and the number information n, which is the number of unused units, is decreased by 1, and the same value n is stored in all the devices A, B, and C. Here, an operation when an abnormality occurs in the apparatus B after the number information n becomes “0” will be described with reference to FIG. 4. When an abnormality occurs in the AC / DC conversion device (for example, reference numeral 52) constituting the power supply device 5 in the device B (step S2 in FIG. 4, an abnormality detection step), the number information from the number information storage unit 44 in the device B. Although n is read, since the number information n = “0” (Yes in step S3), the process proceeds to step S8. Then, the service processor 4 of the device B instructs the degeneration of the device B itself, and stops the operation of the device B (step S8 in FIG. 4, power supply incorporation step). As a result, in the case where the power supply for abnormality has occurred but the redundant power supply is insufficient and cannot be recovered, the apparatus B in which the abnormality has occurred can be quickly disconnected, and adverse effects on the system can be suppressed. be able to. In the above description, the case where the device to be degenerated is of the code B has been described, but the same applies to the devices A and C.

  As described above, according to the present invention, the redundant power supply device 3 is installed in one device A constituting the system, and this can be shared by all the devices A, B, and C. Low cost and low power consumption Thus, the power supply redundancy function can be realized, and the reliability of the system can be improved. In particular, since the number of AC / DC converters constituting the redundant power supply device 3 is matched and managed in all the devices A, B, and C, it is possible to take quick action when a power supply abnormality occurs. it can. For example, when an unused redundant AC / DC converter remains, the restoration process can be executed, and when it does not remain, it can be quickly degenerated.

  Here, in the above, the case where each of the service processors 1, 4 and 6 of all the devices A, B and C constituting the system is equipped with the above-described processing units 11 to 13 and the storage unit 14 is exemplified. However, only one device or another device is equipped with the above processing units 11 to 13 and the like, and the power supply state of all the devices A, B, and C can be monitored and a redundant power supply can be incorporated. May be.

  The power supply control system according to the present invention can be applied when an information processing system is constructed by a plurality of electronic devices, and has industrial applicability.
