  Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram illustrating a configuration of a selective power feeding system 1 including a selective power feeder 100 according to a first embodiment of the present invention.

  In FIG. 1, the selective power feeding system 1 includes a selective power feeder 100 and a plurality of information devices 200. Hereinafter, the information device is referred to as “ICT device”.

  The selective power feeder 100 is an example of a power feeding control device. The plurality of ICT devices 200 is an example of a plurality of devices having a communication function. Each ICT device 200 is, for example, a server, a client, a router, a switch, an access point, a firewall, or a load balancer.

  The selective power feeder 100 communicates with each of the plurality of ICT devices 200 via an NW (network) line 301. The selective power feeder 100 supplies power to each of the plurality of ICT devices 200 via the power line 302.

  FIG. 2 is a diagram illustrating a configuration of the selective power feeder 100.

  In FIG. 2, the selective power feeder 100 includes a computer unit 110, a selective power feeding unit 120, and a network interface 130.

  The computer unit 110 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like.

  The computer unit 110 functions as a power supply device database 111, a grant unit 112, and an operating device determination unit 113 by executing a program recorded in the ROM.

  The power supply device database 111 is an example of a storage unit.

  The power supply device database 111 includes, for each of the plurality of ICT devices 200, the number of connection destination devices connected to the ICT device 200 (hereinafter referred to as “number of connection destination devices”), the traffic amount of the ICT device 200, and the ICT device 200. Power consumption.

  In the present embodiment, the power supply device database 111 stores the number of connection destination devices, the traffic amount, and the power consumption notified from each of the plurality of ICT devices 200.

  The grant unit 112 is an example of a grant unit.

  The assigning unit 112 refers to the power supply device database 111 and assigns a priority regarding power supply to each of the plurality of ICT devices 200 based on the number of connection destination devices and the traffic amount of each of the plurality of ICT devices 200. .

  The assigning unit 112 includes a contribution evaluation unit 112a and a priority determination unit 112b.

  The contribution evaluation unit 112a periodically receives device status information from each ICT device 200 via the network interface 130, and stores the device status information in the power supply device database 111.

  The device status information is information representing the operating status of the ICT device 200, and includes the number of connected devices of the ICT device 200 and the amount of transmission / reception traffic.

  The number of connected devices represents the number of connected devices connected to the ICT device 200 between the previous notification of the device status information by the ICT device 200 and the notification of the current device status information by the ICT device 200. Information.

  The number of connected devices is, for example, the number of IP (Internet Protocol) addresses of connected devices, or the number of combinations of connected device IP addresses and TCP (Transmission Control Protocol) / UDP (User Datagram Protocol) port numbers. It is expressed by

  The transmission / reception traffic amount is the amount of information communicated by the ICT device 200 between the previous notification of the device status information by the ICT device 200 and the notification of the current device status information by the ICT device 200. The amount of transmitted / received traffic is expressed as a bit amount or a byte amount.

  Further, the contribution degree evaluation unit 112a reads out the device state information of each ICT device 200 from the power supply device database 111, and evaluates the contribution degree of each ICT device 200 to the processing work based on the device state information of each ICT device 200. To do. The processing work is a processing work related to a system operation or office work related to a plurality of ICT devices 200.

  It can be considered that a device that greatly contributes to processing operations related to system operation and office work is connected to a large number of ICT devices 200 and generates a large amount of traffic.

  In the present embodiment, the contribution evaluation unit 112a calculates the contribution C_a of the ICT device 200a in which the number of connection destination devices is n and the transmission / reception traffic amount is m using the following equation.

C_a = n × α + m × β (Formula 1)
In (Formula 1), the contribution of the ICT device 200a increases as the contribution C_a increases.

  Here, α and β are weight constants.

  The weight constant is a constant determined by the environment and management policy. For example, increasing the weight α of the number of connected devices increases the contribution of devices (for example, servers) connected to many devices. On the other hand, when the weight β of the transmission / reception traffic amount is increased, the contribution of a device (for example, a router) that transmits / receives a large amount of data increases.

  Based on the contribution of each ICT device 200 calculated by the contribution evaluation unit 112a, the priority determination unit 112b gives priority to power supply (hereinafter simply referred to as “priority”) to each of the plurality of ICT devices 200. Designated).

  In the present embodiment, the priority determination unit 112b applies to each of the plurality of ICT devices 200 based on the contribution of each ICT device 200 and the power consumption of each ICT device 200 in the power supply device database 111. Give priority.

  The priority determination unit 112b calculates the priority P_a of the ICT device 200a whose power consumption is e and whose contribution is C_a using the following equation.

P_a = C_a + e × γ (Formula 2)
In (Expression 2), the priority of the ICT device 200a increases as the value of the priority P_a increases.

  Here, γ is a weight constant.

  The weight constant is a constant determined based on the environment and management policy. For example, when the power consumption weight constant γ is increased, the priority of the ICT device 200 with high power consumption increases.

  The operating device determination unit 113 is an example of a determination unit.

  The operating device determination unit 113 receives a target power supply amount from the outside. For example, the operating device determination unit 113 receives the target power supply amount from the selective power supply unit 120.

  The operating device determination unit 113 receives the priority of each ICT device 200 from the priority determination unit 112b, and reads the power consumption of each ICT device 200 from the power supply device database 111.

  The operating device determination unit 113 assigns a power supply target device to be supplied with power from the plurality of ICT devices 200 within the range in which the total power consumption of the power supply target device falls within the target power supply amount. The priority is determined in descending order.

  In addition, the operating device determination unit 113 is configured so that the total power consumption of the power supply target devices is as close as possible to the target power supply amount as long as the total power consumption of the power supply target devices is within the target power supply amount. From among them, as many power supply target devices as possible are determined in descending order of priority.

  When determining the power supply target device, the operating device determination unit 113 notifies the selected power supply unit 120 of operation information indicating the power supply target device. The operation information is an example of operation target device information.

  The operating device determination unit 113 is periodically notified of power supply information indicating the target power supply amount and the actual power supply amount from the selective power supply unit 120.

  When receiving the power supply information, the operating device determination unit 113 determines whether there is an ICT device 200 (power supply target device) that can additionally operate.

  At this time, the operating device determination unit 113 uses the device status information and the power consumption information when the ICT device 200 was previously operating as the priority of the ICT device 200 that was not operating at that time. To decide.

  On the other hand, when the active device determination unit 113 is notified of an alarm that the actual power supply amount does not fall within the target power supply amount from the selected power supply unit 120, the actual power supply amount indicated in the power supply information is indicated in the power supply information. The ICT devices 200 having lower priority among the power supply target devices are sequentially removed from the power supply target devices until the target power supply amount is reached.

  The operating device determination unit 113 generates new operation information each time the power supply target device is removed, and notifies the selected power supply unit 120 of the new operation information.

  The operating device determination unit 113 determines the ICT device 200 removed from the power supply target device as an operation stop device. The operation stop device is a device other than the power supply target device among the plurality of ICT devices 200.

  The selective power supply unit 120 is an example of an execution unit.

  The selective power supply unit 120 periodically measures the power consumption of the ICT device 200 and stores the measurement result in the power supply device database 111.

  The selective power supply unit 120 receives a target power supply amount from the outside. The selective power supply unit 120 receives a target power supply amount from, for example, an input unit (not shown) that receives an administrator input.

  The selective power supply unit 120 periodically notifies the operating device determination unit 113 of power supply information indicating the target power supply amount and the current actual power supply amount.

  In addition, the selected power supply unit 120 notifies the operating device determination unit 113 of an alarm that the current power supply amount exceeds the target power supply amount and does not fall within the target power supply amount.

  When the operation information is notified from the operating device determination unit 113, the selective power supply unit 120 supplies power to the power supply target device indicated in the operation information. Furthermore, the selective power supply unit 120 supplies power only to the power supply target device indicated in the operation information.

  The ICT device 200 shown in FIG. 1 periodically notifies device status information to the selected power feeder 100 via the NW line 301.

  Next, the operation of this embodiment will be described.

  FIG. 3 is a flowchart for explaining the operation of the present embodiment.

  When the operation of the selective power feeder 100 starts, it enters an initial state of periodic operation (hereinafter referred to as “idle state”) (S400). Hereinafter, it is assumed that the selective power supply unit 120 receives the target power supply amount in this situation.

  Subsequently, the contribution evaluation unit 112a periodically collects the device status information from each ICT device 200 by receiving the device status information from each ICT device 200 (S401). When collecting the device state information, the contribution evaluation unit 112 a stores the device state information in the power supply device database 111.

  Subsequently, the selective power feeding unit 120 measures the power consumption of each ICT device 200 (S402). When the selected power supply unit 120 measures the power consumption of each ICT device 200, the selected power supply unit 120 stores the power consumption of each ICT device 200 in the power supply device database 111.

  Subsequently, the selected power supply unit 120 measures the actual power supply amount at the present time, and notifies the operating device determination unit 113 of power supply information indicating the current actual power supply amount and the target power supply amount.

  When receiving the power supply information, the operating device determination unit 113 compares the actual power supply amount at the current time indicated in the power supply information with the target power supply amount.

  When the actual power supply amount at the current time does not fall within the target power supply amount, the operating device determination unit 113 notifies the priority determination unit 112b of a priority recalculation instruction to execute priority recalculation.

  Upon receiving the priority recalculation instruction, the priority determination unit 112b notifies the contribution evaluation unit 112a of a contribution recalculation instruction for executing the contribution recalculation.

  Upon receiving the contribution recalculation instruction, the contribution evaluation unit 112a refers to the power supply device database 111 and calculates the contribution of each ICT device 200 (S403). The contribution evaluation unit 112a periodically calculates the contribution of each ICT device 200 without receiving a contribution recalculation instruction. After calculating the contribution of each ICT device 200, the contribution evaluation unit 112a notifies the priority determination unit 112b of the contribution of each ICT device 200.

  Upon receiving the contribution of each ICT device 200, the priority determination unit 112b prioritizes each ICT device 200 based on the contribution of each ICT device 200 and the power consumption of each ICT device 200 in the power supply device database 111. The degree is calculated (S404).

  After calculating the priority of each ICT device 200, the priority determination unit 112b notifies the operating device determination unit 113 of the priority of each ICT device 200.

  When the priority of each ICT device 200 is received, the operating device determination unit 113 receives the power consumption measured in S402 (power consumption stored in the power supply device database 111) and the ICT device 200 calculated in S404. A power supply target device is determined based on the priority and the target power supply amount (S405).

  When determining the power supply target device, the operating device determination unit 113 notifies the selected power supply unit 120 of operation information indicating the determined power supply target device.

  Upon receiving the operation information, the selected power supply unit 120 supplies power only to the power supply target device indicated in the operation information (S406). Thereafter, the selective power feeder 100 returns to the idle state.

  Here, in the above description, the collection of the device state information in S401 and the measurement of the power consumption in S402 are continuously performed. However, the operation may be periodically performed at different timings.

  In the above description, it has been described that increasing the weight α of the number of connected devices increases the contribution of a device (such as a server) connected to many devices. However, when stopping such an ICT device 200, A device whose power consumption is reduced by stopping the ICT device 200 may be stopped at the same time. For example, since the client cannot be used when the server is stopped, the client may be stopped together with the server.

  In the above description, when the weight β of the transmission / reception traffic amount is increased, the contribution degree of a device (such as a router) that transmits and receives a large amount of data increases. However, when stopping such an ICT device 200, the ICT device A device whose power consumption is reduced by stopping 200 may be stopped at the same time. For example, when a switch in the middle of a network path is stopped, a router, a switch, an access point, a firewall, and a load balancer related to the switch may be stopped together with the switch.

  The two examples described above are realized as follows, for example.

  The power supply device database 111 further stores related device information representing a device whose power consumption decreases as power supply to a predetermined device (for example, a server or a router) among the plurality of ICT devices 200 is stopped. Then, the operating device determination unit 113 determines a device other than the power supply target device among the plurality of ICT devices 200 as an operation stop device, and when the predetermined device is determined as an operation stop device, it is displayed in the related device information. The determined device is determined not as a power supply target device but as an operation stop device.

  In the above description, the selective power feeding system 1 is composed of the selective power feeder 100 and a plurality of ICT devices 200. However, the selective power feeding system 1 includes a power output such as a generator such as a solar power generator or a storage battery. There may be a device. In this case, using the target power supply amount as the external power supply amount, the operation of the ICT device 200 is determined so that the external power supply amount becomes the target value. For example, depending on the amount of power generated by the generator and the remaining amount of the storage battery, a device with a low priority can be operated. This example is realized as follows, for example.

  The operating device determination unit 113 selects a power supply target device from a plurality of ICT devices 200 within a range in which the total power consumption of the power supply target device falls within the total of the power supplied from the power output apparatus and the target power supply amount. The priority assigned by the assigning unit 112 is determined in descending order.

  For example, the operating device determination unit 113 determines that the total power consumption of the power supply target device is within the range where the total power consumption of the power supply target device is within the total of the power supplied from the power output device and the target power supply amount. From among the plurality of ICT devices 200, power supply target devices are determined in descending order of priority given by the assigning unit 112 so as to be closest to the sum of the power supplied from the output device and the target power supply amount.

  In the above description, the ICT device 200 notifies the selected power feeder 100 of the device status information. However, the selected power feeder 100 may periodically inquire the ICT device 200 about the device status.

  In the above description, the selective power feeding unit 120 measures the power consumption of each ICT device 200. However, if the ICT device 200 has a function of measuring the power consumption, the power consumption measured by the ICT device 200 is measured. May be included in the device status information and notified to the selected power feeder 100.

  Next, the effect of this embodiment will be described.

  According to the present embodiment, the power supply device database 111 stores, for each of a plurality of ICT devices, the number of connection destination devices connected to the ICT device, the traffic amount of the ICT device, and the power consumption of the ICT device. . The number of connection destination devices connected to the ICT device and the traffic amount of the ICT device represent the contribution of the ICT device to system operation and office work.

  The assigning unit 112 assigns a priority regarding power feeding to each of the plurality of ICT devices 200 based on the number of connection destination devices and the traffic amount of each of the plurality of ICT devices.

  For this reason, it becomes possible to give priority to each of the ICT equipment 200 based on the contribution to the system operation and office work.

  The operating device determination unit 113 receives the target power supply amount, and then sets the power supply target device having a high priority from the plurality of ICT devices 200 within a range where the total power consumption of the power supply target device is within the target power supply amount. Determine in order. The selective power supply unit 120 performs power supply to the power supply target device.

  For this reason, it is possible to achieve the power supply target with minimum influence on system operation and office work. This effect is also achieved by a selective power feeding unit including the power feeding device database 111, the granting unit 112, the operating device determining unit 113, and the selective power feeding unit 120.

  In the present embodiment, the assigning unit 112 assigns a priority to each of the plurality of devices based on the number of connection destination devices, the traffic amount, and the power consumption of each of the plurality of ICT devices.

  For this reason, it is possible to give priority to each of a plurality of devices in consideration of power consumption in addition to the degree of contribution to system operation and office work.

  The selective power feeder 100 may be configured by a computer. This computer reads and executes a program recorded on a computer-readable recording medium, and functions as the power supply device database 111, the assigning unit 112, the operating device determination unit 113, and the selective power supply unit 120.

  Next, a second embodiment of the present invention will be described with reference to the drawings.

Hereinafter, the selective power feeder 100A will be described focusing on differences from the first embodiment.

  The selected power feeder 100A includes an operating device determination unit 113A instead of the operating device determination unit 113 illustrated in FIG.

  The operating device determination unit 113A is an example of a determination unit. The operating device determination unit 113A has a function of notifying the ICT device 200 of operating information in addition to the functions of the operating device determination unit 113. Thus, since each ICT device 200 knows in advance whether or not it can continue to operate, even if it is stopped, it can be safely stopped before the power supply is stopped.

  Note that the selective power feeder 100A may be configured by a computer. This computer reads and executes a program recorded on a computer-readable recording medium, and functions as the power supply device database 111, the assigning unit 112, the operating device determination unit 113A, and the selective power supply unit 120.

  Next, a third embodiment of the present invention will be described with reference to the drawings.

  FIG. 5 is a diagram showing a configuration of a selective power feeding system 1B including a selective power feeder 100B according to the third embodiment of the present invention. In FIG. 5, the same components as those shown in FIG. Hereinafter, the selective power feeding system 1B will be described with a focus on differences from the first embodiment.

  In FIG. 5, the selective power feeding system 1 </ b> B includes a selective power feeder 100 </ b> B, a power feeding dedicated selective power feeder 300, and a plurality of ICT devices 200.

  The power feeding dedicated selective power feeder 300 has a part of the function of the selective power feeding function unit 120 shown in FIG.

  The power supply dedicated selection power supply 300 periodically measures the power consumption of the ICT device 200 and notifies the selected power supply 100B.

  In addition, when the operation information is notified from the selection power supply 100B, the power supply dedicated selection power supply 300 performs power supply only to the power supply target device indicated in the operation information.

  FIG. 6 is a diagram illustrating a configuration of the selective power feeder 100B. In FIG. 6, the same components as those shown in FIG. Hereinafter, the selective power feeder 100B will be described focusing on differences from the second embodiment.

  The selective power supply unit 120B is an example of a notification unit.

  The selective power supply unit 120 </ b> B periodically collects and aggregates the power consumption of the ICT device 200 in the selective power supply system 1 </ b> B from the power supply dedicated selection power supply 300 and stores it in the power supply device database 111.

  The selected power supply unit 120B receives a target power supply amount from the outside, and periodically notifies the operating device determination unit 113A of power supply information indicating the target power supply amount and the current actual power supply amount.

  In addition, when the current actual power supply amount exceeds the target power supply amount, the selected power supply unit 120B notifies the operating device determination unit 113A of an alarm that the power supply amount does not fall within the target power supply amount.

  In addition, when the operation information is notified from the operating device determination unit 113A, the selective power supply unit 120B supplies power only to the ICT device 200 to be supplied in accordance with the operation information. Is sent to the power feeding dedicated selection power feeder 300.

  According to this embodiment, the expandability of the selective power feeding system 1B can be increased.
