Description

  The present invention relates to a technique for inspecting a connection relationship between a plurality of servers and a plurality of uninterruptible power supplies that supply power to the servers.

  A UPS (Uninterruptible Power Supply) is a power supply device used for a server or the like that needs to prevent operation from being stopped when a power failure occurs. The UPS and the server are generally connected by a power line (power cable). The connection relationship between the UPS and the server (for example, the wiring connection relationship and the energized state (power supply state). The same applies hereinafter) is required to be visually confirmed by an operator during system construction and periodic inspection. As the number of UPS and servers increases, the work becomes very complicated.

  In order to solve this problem, there is a technology called power line communication (PLC) that uses a power line as a communication line. Non-Patent Document 1 discloses a control method using PLC. Note that the PLC requires a power line carrier communication device (modem) that functions as a relay on a route from a wired LAN (Local Area Network) to a power line and from the power line to the next wired LAN.

  Patent Document 1 discloses a system for managing and notifying UPS abnormalities.

  Next, an embodiment of the present invention will be described with reference to the drawings. In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. However, the drawings schematically show the configuration of the embodiment of the present invention. Furthermore, the embodiment of the present invention described below is an example, and can be appropriately changed within a range in which the essence is the same.

<First Embodiment>
(Power control system)
A configuration example of the power supply control system 100 according to the first embodiment of the present invention will be described with reference to FIG.

  A power control system 100 according to the first embodiment of the present invention includes a power control device 1, a switch unit 2, a UPS 3, servers 4, 4a, 4b, and 4c (hereinafter referred to as servers 4 to 4c), a power cable 5, and A network 6 is provided.

  In the power supply control system 100, the power supply control device 1 controls the power on and off (start and end of power supply) from the UPS 3 to the servers 4 to 4 c via the switch unit 2. When power is supplied from the UPS 3 and the servers 4 to 4 c are activated, the servers 4 to 4 c notify the power supply control device 1 via the network 6 that the servers 4 to 4 c are activated. In this embodiment, this notification is performed when the servers 4 to 4c are started. This notification includes information for identifying each of the servers 4 to 4c. Based on the received notifications, the power supply control device 1 determines whether the power is supplied between the UPS 3 and the servers 4 to 4c, that is, whether the wiring is correctly performed or whether there is an abnormality in the devices on the network 6. Inspect etc. Details of the power supply control device 1 will be described later.

  The switch unit 2 controls the start and end of power supply from the UPS 3 to the servers 4 to 4 c in accordance with an instruction from the power supply control device 1.

  The UPS 3 is a kind of power supply device, and has a built-in device for storing power, such as a secondary battery. Even if the power supply from the outside is interrupted due to a power failure or the like, the servers 4 to 4c on the network 6 are output for a certain period of time. Can be supplied with electric power.

  The UPS 3 can be controlled by an arbitrary program. As an example, a case where an SNMP (Simple Network Management Protocol) card is used will be described. In this case, the UPS 3 includes a card slot (not shown) for inserting the SNMP card. The SNMP card stores a network management program, and the UPS 3 reads the program from the SNMP card and executes network management according to the read program.

  The servers 4 to 4c are server devices that perform specific processing. The servers 4 to 4c may be general-purpose servers or servers that perform highly urgent processing. A server that performs processing with high urgency is a server that needs to be prevented from shutting down in particular because it causes serious damage to the system when the power is turned off and the system is shut down. Highly urgent processing includes, for example, processing at a medical site related to human life, processing of important data related to operations that operate for 24 hours, and the like.

  As shown in FIG. 1, the UPS 3 and the servers 4 to 4 c are connected one-to-one or one-to-many. A combination of one UPS 3 and at least one or more servers 4 to 4c connected thereto is referred to as “device combination” in the following description. For example, the three UPSs 3 on the left side of FIG. 1 and the three servers 4 (device combinations A, B, and C) are connected in series in a one-to-one relationship. On the other hand, one UPS 3 on the right side of FIG. 1 and servers 4a, 4b, and 4c (device combination D) are connected in parallel in a one-to-many manner.

  The power cable 5 is a cable for connecting between the switch unit 2 and each UPS 3 and between each UPS 3 and the servers 4 to 4c.

The network 6 is a network composed of wired, wireless, or a combination thereof for enabling data communication among the UPS 3, the servers 4 to 4 c and the power supply control device 1.
(Power control device)
As shown in FIG. 2, the power supply control device 1 includes a control unit 7a and a storage unit 1g. The control unit 7a includes a power management unit 1a, a notification reception unit 1b, a calculation unit 1c, a determination unit 1d, a result display unit 1e, and a setting unit 1f. The storage unit 1g stores a work memory 1h and a determination table memory 1i. The configuration shown in FIG. 2 is an example, and the present embodiment is not limited to this.

  The work memory 1h includes a history memory that temporarily stores the reception time each time the control unit 7a receives a notification sent from the servers 4 to 4c. Note that the data in the history memory may be deleted after a predetermined time has elapsed. The working memory 1h includes a counter memory that stores the number of times the power is turned on.

  The decision table memory 1i stores decision table data including a time (hereinafter referred to as an interval) that should be taken from one notification to the next notification as a time interval based on the device combination. FIG. 3 shows determination table data stored in the determination table memory. The determination table data includes an identifier that can identify the UPS 3, for example, 3a, 3b, 3c, and 3d, and an interval (seconds) from a certain power supply to the start of the next power supply. Each interval is stored in association with an identifier.

  The power management unit 1a controls the switch unit 2 to manage power on / off for the UPS 3. The power management unit 1a supplies power from the UPS 3 to the servers 4 to 4c at different times (timing).

  The notification receiving unit 1b receives from the servers 4 to 4c a notification notifying that it has been activated, and acquires information (for example, an IP address) that can identify the servers 4 to 4c included in the notification. The notification receiving unit 1b stores the notification reception time together with the identifiable information in the history memory in the working memory 1h. Furthermore, the notification receiving unit 1b increases the number of counter memories in the working memory 1h every time a notification is received.

  The calculation unit 1c reads the history memory in the working memory 1h, and calculates the elapsed time from the reception time of one notification to the reception time of the next notification based on the reception time stored in the history memory.

  The determination unit 1d obtains device combinations A to D of the UPS 3 and the servers 4 to 4c based on the notification received by the notification reception unit 1b, and uses the obtained combinations to connect the UPS 3 and the servers 4 to 4c. The relationship (for example, power supply state) is determined. Specifically, the determination unit 1d compares the calculated elapsed time with the interval (seconds) in the determination table data shown in FIG. 3, and determines whether there is a matching value. Accordingly, the determination unit 1d determines a device combination of the UPS 3 and the servers 4 to 4c. This is because the interval of the judgment table data has a value reflecting the device combination. Further, according to the determination result, the determination unit 1d determines the power supply state between the UPS 3 and the servers 4 to 4c in each device combination. When the determination unit 1d compares the times, it is preferable that the determination includes a certain time error (margin) in consideration of a communication delay or the like.

  The result display unit 1e displays the determination result of the determination unit 1d to a system administrator or the like. For example, the result display unit 1e displays the diagnosis result on a monitor (not shown). In addition, the result display unit 1e may make the determination result known by turning on a lamp (not shown) mounted on the power supply control device 1 or the like. It should be noted that known methods for determining the result of lighting of the lamp include a method of lighting a different lamp, a method of changing a light emission period, a method of changing the color of the lamp, and the like according to the determination result.

The setting unit 1f sets a timing for transmitting a notification to each of the servers 4 to 4c, that is, an interval between a notification and the next notification. The setting unit 1f stores the set interval in the determination table memory 1i.
(Operation of power control system)
The operation of the power supply control system 100 will be described with reference to the drawings.

  First, the operation in which the power supply control device 1 sets the timing for receiving notifications from the servers 4 to 4c will be described with reference to the flowchart of FIG.

  First, in step S101, the setting unit 1f of the power supply control device 1 sets the number of times to be notified from the servers 4 to 4c (the same number for all servers). Further, the setting unit 1 f sets an interval for switching (turning on and off) the power supply to the UPS 3 for each device combination. All the UPSs 3 are turned off (OFF) after a predetermined time, for example, 1 second has elapsed after the power is turned on (ON). The time from power ON to power OFF is the same. However, as shown in FIG. 3, the time from power OFF to ON varies for each UPS and for each ON frequency.

  This operation will be described with reference to a timing chart shown in FIG. In this timing chart, the number of times each UPS is turned on is three. The UPS 3a is turned on for the second time after A seconds after it is turned off for the first time (for example, this interval is 1 second). That is, the time from the first ON to the second ON is (1 + A) seconds. The UPS 3a is turned off for the third time after B seconds after being turned off for the second time. That is, the time from the second ON to the third ON is (1 + B) seconds.

  Similarly, the UPS 3b becomes the second ON state after C seconds from the first ON to the OFF. That is, the time from the first ON to the second ON is (1 + C) seconds. The UPS 3b becomes the third ON state after D seconds after the second ON to OFF. That is, the time from the second ON to the third ON is (1 + D) seconds.

  In step S102, the setting unit 1f of the power supply control device 1 stores the set interval in the determination table memory 1i (FIG. 3) for each device combination.

  Thus, the operation for setting the timing for receiving the notification from each of the servers 4 to 4c is completed.

  Next, in the power supply control system 100, the operation in which the power supply control device 1 confirms the power supply state of each device combination will be described with reference to the flowchart of FIG. The work memory 1h preferably includes as many counter memories as the number of servers 4 to 4c. In addition, it is assumed that the power control device 1 has preset the number of times to be notified from the servers 4 to 4c.

  First, in step S201, the control unit 7a of the power supply control device 1 instructs to start up the UPS 3. Specifically, the power management unit 1 a turns on the power of the UPS 3 of any of the device combinations A to D via the switch unit 2. As a result, one UPS 3 is activated (step S202). Further, the servers 4 to 4c connected to the UPS 3 are activated upon receiving power supply (step S203).

  In step S204, the servers 4 to 4c that are combined with the UPS 3 are activated, and send a notification notifying the activation to the control unit 7a via the network 6.

  In step S205, when the notification receiving unit 1b receives the notification, the reception time of the notification is stored in the history memory in the work memory 1h. Further, the notification receiving unit 1b determines the transmission source servers 4 to 4c from the identifiers of the servers 4 to 4c included in the notification, and increments the counter memory corresponding to the server in the work memory 1h by one.

  In step S206, the determination unit 1d determines whether this notification is the last notification, that is, whether the number of counter memories is equal to or greater than a preset number. If it is not the last notification, the process proceeds to step S207. If it is the last notification, the process proceeds to step S211.

  In step S207, after a predetermined time elapses (for example, 1 second after power-on (ON)), the power management unit 1a instructs the switch unit 2 to turn off the UPS 3 of the device combination related to the notification. In accordance with this instruction, the switch unit 2 turns off the power of the UPS 3 (step S208), and accordingly, the servers 4 to 4c are turned off (step S209). Note that the predetermined time from power-on to power-off may be different for each power supply or each combination.

  In step S210, the power management unit 1a determines the predetermined number described in the determination table data from the number of counter memories of the servers 4 to 4c in the work memory 1h and the UPS 3 that is a device combination with the servers 4 to 4c. Get the time. For example, assuming that the counter memory is the first time and the UPS identifier is 3a, the power supply stop state is continued for 10 seconds with reference to the determination table data shown in FIG. After the predetermined time has elapsed, the power management unit 1a returns to step S201 and executes power-on to the UPS 3.

  In step S211, the calculation unit 1c acquires the first to third power-on (ON) times related to the transmission source servers 4 to 4c from the history memory in the work memory 1h. The calculation unit 1c calculates the time from the first ON to the second ON and the time from the second ON to the third ON (see FIG. 5).

  In step S212, the determination unit 1d acquires an interval corresponding to the UPS 3 that is a device combination with the transmission source servers 4 to 4c from the determination table memory 1i (see FIG. 3), and the time interval acquired by the calculation unit 1c. Compare with For example, in the case of the UPS with the identifier 3a shown in FIG. 3, the time from the first ON to the second ON is 10 seconds, and the time from the second ON to the third ON is 3 seconds. If the actually acquired times are equal to these times, the determining unit 1d determines that the power supply to the device combination of the UPS 3 of the identification 3a and the server is successful. On the other hand, if it is not equal to these times, the determination unit 1d determines that power supply to the UPS3 device combination has failed, that is, there is an abnormality somewhere. In this determination, it is desirable to give a predetermined margin in consideration of communication delay and the like.

  In step S213, the result display unit 1e displays the determination result of the determination unit 1d on a screen (not shown) or the like.

  Finally, in step S214, the determination unit 1d determines whether the processing in steps S201 to S213 has been executed for all the device combinations A to D. When the process is not executed for all the device combinations A to D, the determination unit 1d selects the UPS 3 of the unprocessed device combination, and returns the process to step S201. Note that the order in which the processes are executed may be determined in advance.

  Modification 1 of the first embodiment will be described.

  In the above description, it has been described that the power supply control device 1 controls the turning on and off of all the power. However, the UPS 3 is autonomously controlled to execute the preset turning on and off of the power. Is also possible. In this case, after the power is turned off in step S208, the UPS 3 stands by in an OFF state for a set number of seconds (such as (1 + A) seconds in FIG. 5) (step S210), and then starts itself (step S202). . The UPS 3 ends the operation when all of the preset power on and off are completed. After determining that the last notification has been received in step S206, the power supply control device 1 executes the processes of steps S211 to S213.

  In the case of the first modification, the counter memory for each device combination is not necessary in the work memory 1h of the power supply control device 1.

  Modification 2 of the first embodiment will be described.

  In the first embodiment, power supply to the UPS 3 of each of the device combinations A to D is sequentially turned on (in series), and the success of power supply is determined. However, power supply to the UPS 3 of all the device combinations A to D may be performed simultaneously (in parallel) or partially simultaneously. FIG. 7 shows a power supply control device 1A according to Modification 2 of the first embodiment. The power supply control device 1A includes a control unit 7A and a storage unit 1g. The control unit 7A includes a power management unit 10a, a notification reception unit 1b, a calculation unit 1c, a determination unit 1d, a result display unit 1e, and a setting unit 1f. The storage unit 1g stores a work memory 1h and a determination table memory 1i. The power management unit 10a simultaneously turns on each of the UPSs 3 of the device combinations A to D that are activated simultaneously via the switch unit 2.

  Operation | movement of 1 A of power supply control apparatuses which concern on the modification 2 of 1st Embodiment is demonstrated. In the above step S201, when the control unit 7A of the power supply control device 1A instructs to start up the UPS 3, the power management unit 10a supplies the power of the UPS 3 of the device combinations A to D to be started simultaneously via the switch unit 2. Each. As a result, the UPSs 3 to be activated are activated at the same time. Other configurations and operations are the same as those in the first embodiment.

  Modification 3 of the first embodiment will be described.

  In this embodiment, the notification is performed when the servers 4 to 4c are started. However, the transmission timing of this notification is not limited to this, and may be notified when the servers 4 to 4c are ended (stopped). It may be notified at the time of starting and ending 4c. This can be done by setting the notification timing in the servers 4 to 4c in advance.

  A case where notification is made when the server is terminated will be described with reference to the flowchart of FIG. In this case, after the servers 4 to 4c are activated (step S203), when the servers 4 to 4c finish their operations (the power is turned off) in step S215, the servers 4 to 4c are switched to the power control device 1 in step S204. Is notified of the end. This end instruction may be set in advance so as to end automatically after a predetermined interval (for example, 10 seconds) after the server is started. Alternatively, an end instruction may be sent from the power supply control device 1 after a predetermined interval. This end notification is received by the notification receiver 1b of the power supply control device 1 (step S205). Other configurations are the same as those of the first embodiment. The contents of the flowchart shown in FIG. 8 are the same as the contents of steps S201 to S206 and steps S210 to 214 in the flowchart of FIG. 6 of the first embodiment.

  A case where notification is given at the time of starting and ending the server will be described with reference to the flowchart of FIG. In this case, after the server 4 to 4c is notified of activation (step S204), when the server 4 to 4c finishes operating (the power is turned off) in step S215, the process is returned to step S204. ˜4c notifies the power supply control device 1 of the end. This end instruction may be set in advance so as to end automatically after a predetermined interval (for example, 10 seconds) after the server is started. Alternatively, an end instruction may be sent from the power supply control device 1 after a predetermined interval. Notifications of activation and termination are received by the notification receiver 1b of the power supply control device 1 (step S205). Other configurations are the same as those of the first embodiment. The contents of the flowchart shown in FIG. 9 are the same as the contents of steps S201 to S206 and steps S210 to 214 in the flowchart of FIG. 6 of the first embodiment.

  These modified examples 1 to 3 can also be applied to the second to fourth embodiments described later.

  As described above, according to the first embodiment of the present invention, the connection relationship between the UPS 3 and the servers 4 to 4c, i.e., the wiring connection relationship and the power supply state, is costly checked without visual confirmation in advance. Inspection (understands the connection relationship) without any problems. That is, it is possible to confirm the power supply state between the devices without checking the wiring connection relationship by visual inspection or the like and without introducing a device such as PLC. This is because the power management unit 1a controls the supply of power from the UPS 3 to the servers 4 to 4c connected to the UPS 3, and the determination unit 1d receives a notification from the servers 4 to 4c activated in response to the supply. This is because a combination of the UPS 3 and the servers 4 to 4c is obtained based on the notification, and the connection relation is determined using the combination.

<Second Embodiment>
In the first embodiment, the power supply control system 100 determines the connection relationship between the UPS 3 and the servers 4 to 4c based on the reception time difference of notifications received from the servers 4 to 4c. In the second embodiment, a power supply control system 200 that determines the connection relationship between the UPS 3 and the servers 4 to 4c based on the number of notifications received from the servers 4 to 4c will be described.
(Power control system)
As shown in FIG. 10, the power supply control system 200 according to the second embodiment of the present invention includes a power supply control device 10, a switch unit 2, a UPS 3, servers 4 to 4 c, a power cable 5, and a network 6.

  As shown in FIG. 11, the power supply control apparatus 10 includes a control unit 7b and a storage unit 10g. The control unit 7b includes a power management unit 1a, a notification reception unit 10b, a determination unit 10d, a result display unit 1e, and a setting unit 10f. The storage unit 10g stores a work memory 10h and a determination table memory 10i.

  The work memory 10h includes a notification counter memory that stores the number of receptions each time the control unit 7b receives notifications sent from the servers 4 to 4c. Note that the data in the memory may be deleted after a predetermined time has elapsed.

  The determination table memory 10 i stores determination table data including an interval that should be taken from one notification to the next notification as a time interval based on the device combinations A to D. FIG. 12 shows determination table data stored in the determination table memory. The determination table data includes identifiers that can identify the UPS 3, for example, 3a, 3b, 3c, and 3d, and the number of times each UPS 3 should be powered on. Based on the determination table memory 10i, the power management unit 1a supplies power from the UPS 3 to the servers 4 to 4c at different times.

  The notification receiving unit 10b receives from the servers 4 to 4c notification that it has been activated, and acquires information for identifying the servers 4 to 4c from the notification. The notification receiving unit 10b specifies a server based on the identification information, and increases the value of the notification counter memory of the UPS 3 that is combined with the specified server.

  The determination unit 10d compares the value of the notification counter memory in the work memory 10h with the value (number of times) of the determination table data shown in FIG. 12, and determines whether the values match. Further, according to the determination result, the determination unit 10d determines the power supply state between the UPS 3 and the servers 4 to 4c.

  The setting unit 10f sets the number of times that the notifications of the servers 4 to 4c should be transmitted. The setting unit 10f stores the set number of times in the determination table data.

Other devices, units, etc. are the same as those in the first embodiment.
(Operation of power control system)
The operation of the power supply control system 200 will be described with reference to the drawings.

  First, the operation in which the power supply control device 10 sets the timing for receiving notifications from the servers 4 to 4c will be described with reference to the flowchart of FIG.

  First, in step S301, the setting unit 10f of the power supply control device 10 sets the number of times to be notified from each of the servers 4 to 4c. This number of times is set to a different value for each of the device combinations A to D. All the UPSs 3 are turned off (OFF) after a predetermined time, for example, 1 second has elapsed after the power is turned on (ON). Then, after a predetermined time, for example, 1 second has elapsed, the power is turned on again (ON). As shown in FIG. 12, the number of times the power is turned on differs for each UPS.

  This operation will be described with reference to a timing chart shown in FIG. In this timing chart, the power ON / OFF switching timing of each UPS is appropriate (for example, every second), but the number of times varies from UPS to UPS. The UPS 3a is turned on twice, the UPS 3b is turned on three times, and the UPS 3c is turned on four times.

  In step S302, the setting unit 10f of the power supply control device 10 stores the set number of notifications in the determination table memory 10i (FIG. 12) for each of the device combinations A to D.

  Thus, the operation for setting the number of times of receiving notifications from the servers 4 to 4c is completed.

  Next, in the power supply control system 200, the operation in which the power supply control device 10 confirms the power supply state of each device combination will be described with reference to the flowchart of FIG. The work memory 10h may include as many notification counter memories as the number of servers 4 to 4c.

  Steps S401 to S404 are the same as steps S201 to S204 in FIG.

  In step S405, when the power supply control device 10 receives a notification notifying activation from the servers 4 to 4c, the notification receiving unit 10b of the power supply control device 10 acquires the identifiers of the servers 4 to 4c included in the notification. Further, the notification receiving unit 10b determines the transmission source servers 4 to 4c based on the acquired identifier, and increments the notification counter memory corresponding to the server in the work memory 10h by one.

  In step S406, the determination unit 10d determines whether there is a notification counter memory having a preset value (see determination table data shown in FIG. 12) among the plurality of notification counter memories. If it is not a preset value, the process proceeds to step S407, and if it is a preset value, the process proceeds to step S411.

  Steps S407 to S409 are the same as steps S207 to S209 in FIG.

  In step S412, the determination unit 10d determines the device combinations A to D in which the value of the notification counter memory has reached a preset number of times (see FIG. 12). That is, it is determined which UPS 3 is combined with the servers 4 to 4c. If the value (actually measured value) in the notification counter memory corresponding to the server is equal to a preset value (see FIG. 12) corresponding to the identifier of the UPS combined with the server, the determining unit 10d It is determined that the power supply to the device combination of the UPS 3 having the identifier and the server is successful. Conversely, if the determination unit 10d does not receive a notification for the number of times that matches a preset value (see FIG. 12), power supply to the UPS3 device combination has failed, that is, there is something wrong. Judge. The determination unit 10d delivers the acquired device combination (UPS3 and servers 4 to 4c) to the result display unit 1e.

  In step S413, the result display unit 1e displays the determination result of the determination unit 10d on a screen (not shown) or the like.

  Finally, in step S414, the determination unit 1d determines whether the processing in steps S401 to S413 has been executed for all the device combinations A to D. When the processing is not executed for all the device combinations A to D, the determination unit 1d selects the unprocessed device combination UPS3 and returns the process to step S401.

  A modification of the second embodiment will be described. In the above description, it has been described that the power supply control device 10 controls the turning on and off of all the power. However, the UPS 3 is autonomously controlled to execute the preset turning on and off of the power. Is also possible.

  As described above, according to the second embodiment of the present invention, the connection relation between the UPS and the server and the power supply state are inspected without grasping the cost without checking in advance (the connection relation is grasped). can do. That is, it is possible to confirm the power supply state between the devices without checking the wiring connection relationship by visual inspection or the like and without introducing a device such as PLC. This is because the power management unit 1a controls the supply of power from the UPS 3 to the servers 4 to 4c connected to the UPS 3, and the determination unit 10d receives a notification from the servers 4 to 4c activated in response to the supply. This is because a combination of the UPS 3 and the servers 4 to 4c is obtained based on the notification, and the power supply state is determined based on the combination.

  Furthermore, in the second embodiment, since the determination is based on an easily countable element such as the number of notifications from the servers 4 to 4c, the power supply state can be reliably grasped.

<Third Embodiment>
In the first embodiment, the power supply control system 100 determines the power supply state between the UPS 3 and the servers 4 to 4c based on the reception time difference of notifications received from the servers 4 to 4c. However, for this determination, it is necessary to take a margin in consideration of the startup delay of the servers 4 to 4c, the communication delay on the network 6, and the like. In the second embodiment, the power supply states of the UPS 3 and the servers 4 to 4c are determined based on the number of notifications received from the servers 4 to 4c. However, in this determination, as the number of servers 4 to 4c increases, the same number of power-on patterns is required. Therefore, in the third embodiment, these advantages are combined, and the power supply state is determined based on the reception time difference of notifications received from the servers 4 to 4c and the number of notifications (that is, different times and different times). The power supply control system 300 will be described.
(Power control system)
As shown in FIG. 16, the power supply control system 300 according to the third embodiment of the present invention includes a power supply control device 20, a switch unit 2, a UPS 3, servers 4 to 4 c, a power cable 5, and a network 6. The UPS 3 and the servers 4 to 4c are divided into, for example, a group 1 and a group 2 for each device combination. This grouping is for easy understanding in the present embodiment and is not an essential element.

  As shown in FIG. 17, the power supply control device 20 includes a control unit 7c and a storage unit 20g. The control unit 7c includes a power management unit 1a, a notification reception unit 20b, a determination unit 20d, a result display unit 1e, and a setting unit 20f. The storage unit 20g stores a work memory 20h and a determination table memory 20i.

  The work memory 20h includes a notification counter memory that stores the number of receptions every time the control unit 7c receives notifications sent from the servers 4 to 4c, and a history memory that temporarily stores the reception time each time a notification is received. Prepare.

  The decision table memory 20i stores decision table data including an interval that should be taken from one notification to the next notification as a time interval based on the device combination. FIG. 18 shows decision table data stored in the decision table memory. The determination table data includes an identifier that can identify the UPS 3, for example, 3a, 3b, 3c, and 3d, and an interval (seconds) from a certain power supply to the start of the next power supply. Each interval is stored in association with an identifier. In the present embodiment, the UPSs 3 are grouped into a group 1, a group 2, etc., as shown in FIG.

  As shown in FIG. 18, the determination table data is set so that the number of times of reception is different such that the number of notifications is 3 for group 1 and the number of notifications is 2 for group 2. The notification interval is set differently in each group. That is, the same interval may exist within another group.

  When the notification receiving unit 20b receives a notification notifying that the server 4-4c has been activated from the servers 4 to 4c, the notification receiving unit 20b acquires information specifying the servers 4 to 4c from the notification. The notification receiving unit 20b specifies a server from the specified information, and increments the notification counter memory corresponding to the servers 4 to 4c in the working memory 20h by 1 for each reception. Furthermore, the notification receiving unit 20b stores the time when the notification is received together with the information corresponding to the server 4-4c in the history memory in the work memory 20h after the notification is received from the server 4-4c.

  The calculation unit 20c reads the history memory in the work memory 20h, and calculates the elapsed time from the reception time of one notification to the reception time of the next notification based on the reception time stored in the history memory.

  The determination unit 20d compares the notification counter memory value in the work memory 20h with the value (number of times) of the determination table data shown in FIG. 18, and determines whether the values match. Furthermore, the determination unit 20d compares the calculated elapsed time with the interval (seconds) in the determination table data illustrated in FIG. 18 to determine whether there is a matching value. Accordingly, the determination unit 20d determines a device combination of the UPS 3 and the servers 4 to 4c. Further, according to the determination result, the determination unit 20d determines the power supply state between the UPS 3 and the servers 4 to 4c in each device combination.

  The setting unit 20f sets the number of times that each of the servers 4 to 4c should transmit a notification and a notification transmission time difference. The setting unit 20f stores the set number of times and the interval in the determination table memory 20i.

Other devices, units, etc. are the same as those in the first embodiment and the second embodiment.
(Operation of power control system)
The operation of the power supply control system 300 will be described with reference to the drawings.

  First, the operation in which the power supply control device 20 sets the number of notifications received and the timing for receiving notifications from the servers 4 to 4c will be described with reference to the flowchart of FIG.

  First, in step S501, the setting unit 20f of the power supply control device 20 divides all the servers 4 to 4c into several groups. This grouping is classified by the ease of visual inspection by the administrator, the ease of data management, the type of connection between the servers 4 to 4c and the UPS 3, and the like. In the following description, as shown in FIG. 16, the device combination in which the server 4 and the UPS 3 are connected in series is divided into the group 1, and the device combination in which the servers 4a to 4c and the UPS 3 are connected in parallel is divided into the group 2. Assuming that Furthermore, the setting unit 20f sets the number of times to be notified from the servers 4 to 4c for each group. This number of times is set to a different value for each device combination in the same group.

  In step S502, the setting unit 20f sets a notification interval for each group. All the UPSs 3 are turned off (OFF) after a predetermined time, for example, 1 second has elapsed after the power is turned on (ON). The time from power ON to power OFF is the same. However, the time from power OFF to ON differs for each UPS in the same group.

  FIG. 20 is a timing chart illustrating an example of the number of notifications to be set and an interval. In the timing chart shown in FIG. 20, the number of times of power-on (ON) is 3 in group 1 and 2 in group 2. Note that UPS3a, UPS3b, and UPS3c belong to group 1, and UPS3d belongs to group 2.

  If it takes 1 second to switch from the ON state to the OFF state, the UPS 3a takes (1 + A) seconds from the first ON to the second ON, and the time from the second ON to the third ON is ( 1 + B) seconds. In the UPS 3b, the time from the first ON to the second ON is (1 + C) seconds, and the time from the second ON to the third ON is (1 + D) seconds. In the UPS 3c, the time from the first ON to the second ON is (1 + E) seconds, and the time from the second ON to the third ON is (1 + F) seconds. In the UPS 3d, the time from the first ON to the second ON is (1 + G) seconds. The time interval until switching from the ON state to the OFF state may be changed according to each device combination, each group, or the like.

  In step S503, the setting unit 20f stores the set interval in the determination table memory 20i (FIG. 18) for each device combination for each group.

  Thus, the operation for setting the number of notifications and the notification reception interval from each of the servers 4 to 4c is completed.

  Next, in the power supply control system 300, the operation in which the power supply control device 20 confirms the power supply state of each device combination will be described with reference to the flowchart of FIG. The work memory 20h may include as many counter memories as the number of servers 4 to 4c.

  First, Steps S601 to S604 are the same as Steps S101 to S104 in FIG.

  In step S605, when the power supply control device 20 receives a notification notifying activation from the servers 4 to 4c, the notification receiving unit 20b of the power supply control device 20 acquires the identifiers of the servers 4 to 4c included in the notification. Furthermore, the notification receiving unit 20b determines the transmission source servers 4 to 4c and the group to which the transmission source servers 4 to 4c belong based on the acquired identifier, and sets the notification counter memory related to the server in the work memory 20h to 1 increase. Further, the notification receiving unit 20b stores the reception time of the notification in the history memory together with information specifying the transmission source servers 4 to 4c.

  In step S606, the determination unit 20d determines whether the value of the notification counter memory has become a preset value. Specifically, it is determined whether the number of times of notification of the group 2 is two times or the number of times of notification of the group 1 is three. If it is not a preset value, the process proceeds to step S607, and if it is a preset value, the process proceeds to step S611.

  Steps S607 to S610 are the same as steps S207 to 210 in FIG.

  In step S611, the calculation unit 20c acquires the power-on (ON) time associated with the transmission source servers 4 to 4c from the history memory in the work memory 20h. The calculation unit 20c calculates the time from the first ON to the second ON, and the like.

  Specifically, consider a case where the processing of UPS 3d of group 2 has been started from step S606. In this case, the calculation unit 20c acquires the first and second power-on (ON) times related to the transmission source servers 4a to 4c from the history memory in the work memory 1h, and obtains the first reception time and 2 The difference time from the second reception time is calculated.

  In step S612, the determination unit 20d acquires an interval corresponding to the UPS 3 that is the combination of the transmission source servers 4 to 4c and the device from the determination table data (see FIG. 18), and compares the interval with the difference time calculated by the calculation unit 20c. .

  Specifically, for example, in the case of the UPS 3d processing of group 2, whether the difference time calculated by the calculation unit 20c matches the “4 seconds” associated with the UPS 3d in the determination table data (see FIG. 18). to decide. If the actually acquired time is equal to these times, the determining unit 20d determines that the power supply to the device combination of the UPS 3 of the identifier 3d and the server has been successful. On the other hand, if it is not equal to these times, the determination unit 20d determines that power supply to the UPS3 device combination has failed, that is, there is an abnormality somewhere.

  In step S613, the result display unit 1e displays the determination result of the determination unit 20d on a screen (not shown) or the like.

  Finally, in step S614, the determination unit 20d determines whether the processing in steps S601 to S613 has been executed for all device combinations. If the process has not been executed for all the device combinations, the determination unit 20d selects the unprocessed device combination UPS3 and returns the process to step S601.

  A modification example of the third embodiment will be described. In the above description, it has been described that the power supply control device 20 controls the turning on and off of all the power. However, the UPS 3 is autonomously controlled to execute the preset turning on and off of the power. Is also possible.

  As described above, according to the third embodiment of the present invention, the connection relation between the UPS and the server and the power supply state are inspected without grasping the cost without checking in advance (the connection relation is grasped). can do. That is, it is possible to confirm the power supply state between the devices without checking the wiring connection relationship by visual inspection or the like and without introducing a device such as PLC. This is because the power management unit 20a controls the supply of power from the UPS 3 to the servers 4 to 4c connected to the UPS 3, and the determination unit 20d receives a notification from the servers 4 to 4c activated in response to the supply. This is because a combination of the UPS 3 and the servers 4 to 4c is obtained based on the notification, and the power supply state is determined using the combination.

  Furthermore, in the third embodiment, device combinations are grouped, the number of notifications is changed according to the group, and the notification interval is changed within each group. It is possible to accurately grasp the power supply state.

<Fourth Embodiment>
The power supply control device 30 according to the fourth embodiment of the present invention is connected to a UPS (not shown) via a power line, and is connected to a server (not shown) via a network. As illustrated in FIG. 22, the power control device 30 includes a power management unit 31 and a determination unit 32. The power supply control device 30 according to the fourth embodiment corresponds to the minimum configuration of the power supply control device according to the first to third embodiments.

  The power management unit 31 controls the supply of power from the uninterruptible power supply to a server connected to the uninterruptible power supply.

  The determination unit 32 receives a notification from the server according to the supply, and determines a combination of the uninterruptible power supply and the server based on the notification.

  The operation of the power supply control device 30 will be described with reference to the flowchart shown in FIG.

  In step S41, the power management unit 31 controls the supply of power from the uninterruptible power supply to the server connected to the uninterruptible power supply. Specifically, the start and end of power supply to the server are controlled. The server for which power supply is started starts. The server notifies the uninterruptible power supply at the start-up, at the end after the start-up, or both.

  In step S42, the determination unit 32 receiving the notification from the server obtains a combination of the uninterruptible power supply and the server based on the notification, and determines the power supply state using the combination.

  According to the fourth embodiment of the present invention, the connection relation between the UPS and the server and the power supply state can be inspected (the connection relation can be grasped) without incurring costs without checking the visual relation beforehand. That is, it is possible to confirm the power supply state between the devices without checking the wiring connection relationship by visual inspection or the like and without introducing a device such as PLC. This is because the power management unit 31 controls the supply of power from the UPS to the server connected to the UPS, and the determination unit 32 receives a notification from the server activated in response to the supply. This is because a combination of the power failure power supply device and the server is obtained, and the power supply state is determined using the combination.

<Fifth Embodiment>
A power supply control device 50 according to the fifth embodiment of the present invention is connected to a plurality of uninterruptible power supply devices (not shown) via a power line, and is connected to a plurality of servers (not shown) via a network. The uninterruptible power supply and the server are connected by a power line (see FIG. 1).

  As shown in FIG. 24, the power control device 50 includes a power management unit 51 and a determination unit 52. The power supply control device 50 according to the fifth embodiment corresponds to a minimum configuration example of the power supply control device according to the first embodiment and a modification of the power supply control device according to the fourth embodiment.

  The power management unit 51 controls the supply of power from the uninterruptible power supply to a server connected to the uninterruptible power supply. The power management unit 51 includes a device combination including an uninterruptible power supply and at least one server. There are multiple device combinations. When power is supplied to each of the device combinations, the power is turned on and off at predetermined time intervals (second time) within a certain period of time (first time). To do.

  An example of turning on and off the power will be described with reference to the timing chart of FIG. The vertical axis of the timing chart indicates the types of device combinations including the uninterruptible power supply devices and their power supply states (ON and OFF). The horizontal axis of the timing chart indicates time (seconds). As shown in FIG. 25, it is assumed that there are three device combinations, and the first time required for power-on (ON), power-off (OFF) and detection thereof for each device combination is, for example, 10 seconds. In this case, the power management unit 51 turns on (ON) the uninterruptible power supply of the first device combination. This power-on time is assumed to be n seconds. Subsequently, the power management unit 51 ends (OFF) power-on of the uninterruptible power supply that has started supplying power after, for example, 8 seconds after the second time elapses from the nth second. Thereafter, the power management unit 51 starts power supply to the uninterruptible power supply of the second device combination after (n + 10) seconds, and ends power supply after the second time. Thereafter, the power management unit 51 starts power supply to the uninterruptible power supply of the third device combination after (n + 20) seconds, and ends power supply after the second time.

  The first and second time settings are made by the power supply control device 50 in which the device combination to be inspected (for example, the first device combination) and the device combination to be inspected next (for example, the second device combination) Are set so that they can be identified on the basis of notifications received from them.

  For example, it is assumed that the power supply control device 50 is set to receive a notification of energization confirmation sent from the server when the power is turned on. In this case, in the first time, the server is energized after the uninterruptible power supply of the first device combination is turned on, and the power supply control device 50 notifies the energization confirmation of the second device combination. Set enough time to receive the uninterruptible power supply before turning it on.

  It is assumed that the power supply control device 50 is set to receive a notification of the end of energization when the power is turned off transmitted from the server. In this case, during the second time, after the power supply being supplied to the uninterruptible power supply of the first device combination is cut off, the power supply control device 50 notifies the disconnection confirmation and supplies power to the second device combination. Set enough time to receive before start (or end).

  When receiving a power-on confirmation notice and a power-on end notice sent when the power is turned off, the two notifications are set to a time sufficient for the power supply control device 50 to receive them. . Various variations may be provided for setting the first and second times.

  The determination unit 52 receives a notification from the server in response to power supply, and determines a combination of the uninterruptible power supply and the server based on the notification. For example, it is assumed that a notification is set to be received when the power is turned on, and it takes 5 seconds to energize the device combination and receive the notification. In this case, when the notification is received after (n + 5) seconds, the determination unit 52 determines that the energization of the first device combination is successful. When the notification is received after (n + 15) seconds, the determination unit 52 determines that the energization of the second device combination is successful. When the notification is received after (n + 25) seconds, the determination unit 52 determines that the energization of the third device combination is successful. Note that the time required to energize the device and receive the notification varies depending on the type of server, the distance from the uninterruptible power supply to the server (the length of the power line), etc. , N seconds, (n + 10) seconds, and (n + 20) seconds, it is only necessary that the notification can be received within a predetermined time interval, for example, within 10 seconds. When the notification is not received within a predetermined time interval, the determination unit 52 determines that the energization has failed.

  The operation of the power supply control device 50 will be described with reference to the flowchart shown in FIG.

  In step S61, the power management unit 51 controls the supply of power to the server connected to the uninterruptible power supply. Specifically, each of a plurality of uninterruptible power supplies is controlled to start (power on) and end (power off) power supply to the server. The server for which power supply is started starts. The server notifies the uninterruptible power supply at the start-up, at the end after the start-up, or both. The power management unit 51 ends the power-on of the uninterruptible power supply that started supplying power after a predetermined interval, for example, 8 seconds.

  In step S62, the determination unit 52 that has received the notification from the server within a predetermined time (first time) obtains a combination of the uninterruptible power supply and the server based on the notification, and uses the combination to determine the power supply state. Judging. For example, when the predetermined time is 10 seconds, in the case of a device combination energized for n seconds, it is determined whether a notification is received from the server of the device combination within (n + 10) seconds. The determination unit 52 determines that the energization has been successful when the notification is received within the predetermined time, and determines that the energization has failed when the notification is not received within the predetermined time. The determination unit 52 may include a memory for temporarily storing the determination result of each device combination. The temporarily stored determination result may be output (displayed) to the user terminal or the like after the inspection is completed.

  If the predetermined time has elapsed in step S63 (YES in step S63), determination unit 52 advances the process to step S64. While the predetermined time has not elapsed (NO in step S63), the process returns to step S62 to execute the determination.

  In step S <b> 64, the power management unit 51 determines whether power supply has been started and ended for all uninterruptible power supply devices. This may be determined by input / output of a signal from an uninterruptible power supply or a server, or may be determined after a predetermined time. For example, when judging with the passage of time, it is judged that the combination of three devices is executed at intervals of 10 seconds, and it is judged that power supply has been started and ended for all uninterruptible power supply devices within 30 seconds from the start. Good. When the power management unit 51 determines that the power supply is not controlled for all the uninterruptible power supply devices, the power management unit 51 returns the process to step S61 and performs the processes of steps S61 to S63 described above for another device combination. Run. When the power supply management unit 51 determines that the power supply control (start and end) has been performed for all uninterruptible power supply devices, the process ends.

According to the fifth embodiment of the present invention, the wiring connection relation and the power supply state between the uninterruptible power supply and the server are inspected (the connection relation is grasped) without incurring costs without checking in advance by visual inspection. be able to. That is, it is possible to confirm the power supply state between the devices without checking the wiring connection relationship by visual inspection or the like and without introducing a device such as PLC. This is because the power management unit 51 controls the supply of power from the uninterruptible power supply to the server connected to the uninterruptible power supply, and the determination unit 52 receives a notification from the server activated in response to the supply, This is because a combination of the uninterruptible power supply and the server is obtained based on the notification, and the power supply state is determined using the combination.
