  The monitoring control device 70 is a computer system having a CPU (Central Processing Unit), ROM, RAM, hard disk, input / output interface, and the like. The control program stored in the ROM or the like causes the CPU to function as at least the arithmetic processing unit 71, and causes the input / output interface or the like to function as at least the acquisition unit 72.

  The acquisition unit 72 is an interface that acquires information on failure states and operational abnormalities output from devices constituting the power supply system 1 such as the power supply device 10, the current distribution device 15, the ICT device 25, and the air conditioning control device 40. is there. The arithmetic processing unit 71 monitors the failure state / operation abnormality of the devices constituting the power supply system 1 based on the information regarding the failure state and the operation abnormality acquired by the acquisition unit 72.

  Next, control in the power feeding system 1 having the above configuration will be described. First, the operation of the power supply system 1 based on employee entry / exit information and information on the ICT device 25 and the like will be described.

  First, a normal operation state in which the ICT device 25 is in a distributed operation will be described with reference to FIG. The distributed operation is a state in which arithmetic processing such as information processing is performed in all ICT devices 25 or most ICT devices 25 in the power feeding system 1.

  In FIG. 2, the percentage described in the ICT device 25 (ICT rack 26) indicates the load factor of the corresponding ICT device. The hatching in the server room SR indicates the temperature of the indoor air in the server room SR, and indicates that the temperature increases as the hatching becomes darker.

  In the server room SR, a power feeding device 10, an air conditioner 35, and an ICT device 25 are arranged. The breakdown of the configuration of the ICT device 25 based on the power consumption base is 80% for server equipment and 20% for network equipment such as switches and routers. In the present embodiment, description will be made by applying to an example in which the total maximum power consumption of the ICT device 25 is 300 kW.

  Next, a description will be given of the case where the integrated linkage control according to the present invention is performed on the power supply system 1 having the above-described configuration. In this description, the integrated control device 60 issues a command to perform a degenerate operation that aggregates loads in the ICT device 25 when the number of employees in the building where the terminal of the ICT device 25 is installed is smaller than a predetermined number. Output. If the load on the ICT device 25 increases during the degenerate operation, the integrated control device 60 outputs a command to release the degenerate operation in advance, and then outputs a command to return to normal distributed operation.

  Here, the control process when executing the degenerate operation will be described with reference to the flowchart of FIG. First, the acquisition unit 64 of the integrated control device 60 executes processing for acquiring entrance / exit information from the entrance / exit management device 65 (S11: acquisition step).

  When the entry / exit information is acquired, the arithmetic processing unit 61 of the integrated control device 60 determines whether the number of employees in the building where the terminal of the ICT device 25 is provided is less than a predetermined fixed number. Processing to determine whether or not is performed (S12: priority processing step). Specifically, a calculation process for obtaining the number of employees in the building based on the entrance / exit information, a process for obtaining a predetermined constant stored in advance in the hard disk of the integrated control device 60, the number of employees in the building and the predetermined number A process of comparing a certain number of.

In the determination process of S12, when it is determined that the number of employees in the building is equal to or larger than a predetermined number (in the case of NO), the arithmetic processing unit 61 stops the process of determining whether or not the degenerate operation is possible.
On the other hand, when it is determined that the number of employees in the building is less than a predetermined number (in the case of YES), the acquisition unit 64 of the integrated control device 60 performs processing for acquiring ICT resource information (S13: priority). Processing steps). Specifically, a process of acquiring information related to the operation of the latest ICT device 25 and air conditioner 35 at the time of performing the acquisition process is performed.

  When the resource information is acquired, the arithmetic processing unit 61 performs processing for determining the priority of control (S14: priority processing step). In the present embodiment, control for reducing the power consumption by controlling the operating status of the ICT device 25 (hereinafter also referred to as “reduction control by the ICT device 25”) and the operating status of the air conditioner 35 are controlled and consumed. Processing for determining the priority order with respect to control for reducing power (hereinafter also referred to as “reduction control by the air conditioner 35”) is performed. Specifically, a process for determining whether or not the reduction control by the ICT device 25 has priority over the reduction control by the air conditioner 35 is performed.

  The prediction processing unit 63 performs a calculation process for estimating an information processing amount such as a calculation in the ICT device 25 based on the number of employees in the building and the acquired resource information. When the amount of information processing such as the estimated calculation increases, the calculation processing unit 61 determines that priority is given to reduction control by the ICT device 25 (YES). On the other hand, if the amount of information processing such as the estimated calculation does not increase, it is determined that priority is given to reduction control by the air conditioner 35 (NO).

  When it is determined in S14 that priority is given to the reduction control by the ICT device 25 (in the case of YES), the arithmetic processing unit 61 determines whether or not a failure has occurred in the ICT device 25 or the like, or hinders operation. The process which determines whether or not is performed (S15). Specifically, the supervisory control device 70 includes the ICT device 25 (hereinafter referred to as “degenerate source ICT device 25”) that is the operation processing transfer source and the ICT device 25 (hereinafter referred to as “degeneration source ICT device 25”). The above-described determination processing is performed based on whether or not information indicating that an abnormality has occurred in the air conditioner 35 or the power supply device 10 is received. If it is determined that a failure has occurred or that the operation will be hindered (in the case of NO), the process for determining whether or not the degenerate operation is possible is stopped. The degeneration source ICT device 25 corresponds to the load source load device in the claims, and the degeneration destination ICT device 25 corresponds to the transfer destination load device in the claims.

  When it is determined that no failure has occurred (in the case of YES), the arithmetic processing unit 61 performs a process of determining whether or not the resources of the ICT device 25 have room (S16). That is, the arithmetic processing unit 61 determines whether or not the resources of the degeneration destination ICT device 25 have room. More specifically, even if the arithmetic processing of the degeneration source ICT device 25 is transferred to the degeneration destination ICT device 25, the CPU usage rate in the degeneration destination ICT device 25 is less than a predetermined value (for example, 80%), It is determined whether or not the usage rate is less than a predetermined value (for example, 80%) and the usage rate of the hard disk (HDD) is less than the predetermined value (for example, 80%). When it is determined that there is no room for resources (in the case of NO), the process for determining whether or not the degenerate operation is possible is stopped.

  When it is determined that there is a margin in resources (in the case of YES), the arithmetic processing unit 61 performs a process of determining whether or not there is a margin in the capacity of the power supply apparatus 10, the switch 16, or the switch 27A (S17). That is, a process of determining whether or not there is a margin in the capacity of the power supply apparatus 10 that supplies a direct current to the degeneration destination ICT apparatus 25, the switch 16, the switch 27A, or the like is performed. More specifically, even if the arithmetic processing of the degeneration source ICT device 25 is shifted to the degeneration destination ICT device 25, the output of the power supply device 10 is less than a predetermined value (for example, 80%) of the rated capacity, the switch 16 and Or whether the current of the switch 27A is less than a predetermined value (80%) of the rated capacity. When it is determined that there is no capacity (NO), the process for determining whether or not the degenerate operation is possible is stopped.

  When it is determined that there is a sufficient capacity (in the case of YES), the arithmetic processing unit 61 performs a process of determining whether there is a sufficient air conditioning capacity (S18). That is, a process for determining whether or not there is a margin in the cooling capacity of the air conditioner 35 that cools the degeneration destination ICT device 25 is performed. More specifically, whether or not the arithmetic processing of the degeneration source ICT device 25 is less than a predetermined value (for example, 80%) of the rated cooling capacity of the air conditioner 35 even if the arithmetic processing of the degeneration source ICT device 25 is shifted to the degeneration destination ICT device 25. Determine. When it is determined that there is no room for air conditioning capability (in the case of NO), the process of determining whether or not the degenerate operation is possible is stopped.

  When it is determined that the air conditioning capacity has a margin (in the case of YES), the integrated control device 60 outputs a command to perform the aggregation process to the ICT control device 30. The ICT control device 30 outputs a command to execute an aggregation process for shifting to the degenerate operation to the target ICT device 25 (S21). When the aggregation process is based on virtualization, the degeneration source ICT device 25 performs live migration to the degeneration destination ICT device 25. After the transfer is completed, the degeneration source ICT device 25 shifts to a dormant state. When the aggregation process is operation suspension of the surplus ICT device 25, the target device is shifted to the suspension state.

  In this embodiment, as shown in FIG. 5, the ICT device 25 mounted on the racks 28A, 28B, 28E, and 28F is the degeneration source ICT device 25, and the ICT device 25 mounted on the racks 28C and 28D is degenerated. Description will be made by applying to the example in which the previous ICT device 25 is used.

  Next, returning to the flowchart of FIG. 3, a process for determining whether or not the ICT resource movement (Guest machine movement) is successful is performed (S22). Specifically, the determination is performed based on whether or not the following five conditions are satisfied. The first is that no hardware failure (hereinafter referred to as “H / W failure”) has occurred in the degeneration destination ICT device 25. Second, there is no H / W failure in the degeneration source ICT device 25. Third, the virtual guest machine of the degeneration source is normal on the virtualization management software. The fourth is that the virtual guest machine to be moved is normal on the degeneration-source virtualization software. The fifth is that there is room in the degenerate destination ICT resource. More specifically, even if the arithmetic processing of the degeneration source ICT device 25 is transferred to the degeneration destination ICT device 25, the CPU usage rate in the degeneration destination ICT device 25 is less than a predetermined value (for example, 80%), The usage rate is less than a predetermined value (for example, 80% of the maximum capacity) and the usage rate of the hard disk (HDD) is less than a predetermined value (for example, 80% of the maximum capacity).

  When it is determined that the movement of the ICT resource has failed (in the case of NO), the process for determining whether or not the degenerate operation is possible is stopped. When it is determined that the ICT resource has been successfully moved (in the case of YES), the integrated control device 60 issues a pause instruction to the ICT control device 30 to the ICT device 25 that is the degeneration source, and pauses to the ICT device 25. A process of determining whether or not the process is successful is performed (S23). Specifically, the determination is performed based on whether or not the following four conditions are satisfied. First, the CPU usage rate is less than or equal to a predetermined value (for example, 5%) and the memory usage rate is less than or equal to a predetermined value (for example, 5%) in the suspension target ICT device 25. Second, there is no virtual guest machine on the suspension target ICT device 25 on the virtualization management software. Third, there is no virtual guest machine on the virtualization software of the suspension target ICT device 25. Fourth, the current consumption of the outlets of the switch 16 and the switch 27A connected to the suspension target ICT device 25 is not more than a predetermined value (for example, 30% of the rated current).

  When it is determined that the pause of the ICT device 25 has failed (in the case of NO), the process of determining whether or not the degenerate operation is possible is stopped. When it is determined that the suspension of the ICT device 25 is successful (in the case of YES), the integrated control device 60 confirms the suspension state information of the ICT device 25 output from the ICT control device 30. After the confirmation, a stop (shutdown) command is issued to the ICT device 25 that has been stopped. After confirming that the ICT device 25 is stopped, the integrated control device 60 instructs the power supply control device 20 to turn off power to the outlet bar 27 on the power supply route, or to the switch 16 or the switch 27A of the current distribution device 15. Output (S31).

  Next, a process of determining whether or not the power supply is turned off in the switch 16 or the switch 27A corresponding to the stopped ICT device 25 is performed (S32). Specifically, processing for determining whether or not the following two conditions are satisfied is performed. First, the connected ICT device 25 is stopped. More specifically, the following three contents are satisfied. Even if a pin (Ping) connection is made to the target ICT device 25, there is no response, connection to the virtualization software of the target ICT device 25 is not possible, connection to the target ICT device 25 via a management network (NW), and power supply Is turned off. Second, the current consumption value of the outlet of the switch 16 or the switch 27A connected to the target ICT device 25 is not more than a predetermined value (for example, 10% of the rated current).

When it is determined that the power supply is not turned off (in the case of NO), the process for determining whether or not the degenerate operation is possible is stopped.
Next, when it is determined that the power supply is turned off (in the case of YES), the integrated control device 60 has an allowance for the temperature of the stopped ICT device 25 to fall, and the air conditioner 35 corresponding to the stopped ICT device 25. The command which stops is output to the air-conditioning control apparatus 40 (S41). The air conditioning control device 40 outputs to the air conditioning device 35 a command to stop the air conditioning device 35 corresponding to the stopped ICT device 25.

  In the present embodiment, as shown in FIG. 5, description will be made by applying to an example in which the air conditioners 35 corresponding to the racks 28A, 28B, 28E, and 28F are stopped. In FIG. 5, feeding OFF is indicated by putting a diagonal line in the corresponding air conditioner 35.

  If the temperature of the air-conditioning zone to which the degeneration destination ICT device 25 belongs increases due to the stop of the air-conditioning device 35 corresponding to the stopped ICT device 25, the air-conditioning control device 40 stops the air-conditioning that has been stopped as necessary. A command for resuming the operation of the device 35 may be output.

  Next, returning to the flowchart of FIG. 3, processing for determining whether or not the air conditioner 35 corresponding to the suspended ICT device 25 is stopped is performed (S <b> 42). Specifically, processing for determining whether or not the following four conditions are satisfied is performed. The first is that the air conditioner 35 corresponding to the ICT device 25 other than the stop target is normal (in other words, no failure has occurred). The second is that the air conditioning device 35 corresponding to the ICT device 25 other than the stop target has a sufficient cooling capacity and is less than a predetermined value (90%) of the rated capacity. Third, the temperature in the vicinity of the suction portion of the ICT device 25 (or Cold Aisle) that is under the jurisdiction of the air conditioner 35 other than the stop target is equal to or lower than the predetermined temperature. . Fourth, the ICT device 25 under the jurisdiction of the air conditioner 35 to be stopped is not operating. More specifically, the ICT device 25 is stopped and the outlet of the switch 16 or the switch 27A connected to the ICT device 25 is OFF.

When it is determined that the air conditioner 35 has not stopped (in the case of NO), the process of determining whether or not the degenerate operation is possible is stopped.
Next, when it is determined that the air conditioner 35 is stopped (in the case of YES), the integrated control device 60 outputs a command to stop the power supply unit 11 corresponding to the stopped ICT device 25 (S51). In other words, since the operating load factor of the power supply device 10 decreases with the stop of the ICT device 25, a command to stop the surplus power supply unit 11 is output to the power supply control device 20.

  Specifically, the number of power supply units 11 mounted on the power supply apparatus 10 is compared with the output current value, and a command to stop the number of power supply units 11 obtained by the following equation is output. Note that the number of power supply units 11 to be stopped may be a number that takes redundancy into consideration for the necessary number of power supply units 11 in consideration of a failure of the power supply unit 11 or a response to a sudden increase in load.

[(The number of power supply units 11 mounted on the power supply apparatus 10) × (capacity of the power supply unit 11 alone) − {(output current) + (capacity of the power supply unit 11 alone)}] / (capacity of the power supply unit 11 alone) ≧ Number of power supply units 11 that can be stopped Next, it is determined whether or not the power supply unit 11 corresponding to the stopped ICT device 25 is stopped (S52). When it is determined that the power supply unit 11 is not stopped (in the case of NO), the process for determining whether or not the degenerate operation is possible is stopped.

  When it determines with the power supply unit 11 having stopped (in the case of YES), the integrated control apparatus 60 performs the process which outputs the instruction | command which turns off the illuminating device 45 (S61). In other words, a turn-off command is output to the lighting control device 50 in order to turn off the lighting device 45 that is no longer needed. After confirming the absence of the worker as necessary, the lighting control device 50 turns off the corresponding part.

  Subsequently, the process which determines whether the illuminating device 45 was light-extinguished is performed (S62). Specifically, a process for determining whether or not the following three conditions are satisfied is performed. The first is that the ICT device 25 has stopped normally. Second, all the corresponding switches 16 or 27A are OFF. Third, the corresponding air conditioner 35 is stopped.

  When it is determined that the lighting device 45 is not turned off (in the case of NO), the process for determining whether or not the degenerate operation is possible is stopped. Moreover, when it determines with the illuminating device 45 having been extinguished (in the case of YES), the process which determines the propriety of degeneration operation is complete | finished.

  In addition, when executing the transition process to the degenerate operation as described above, network control and load control such as SDN (software defined network) technology, NFV (Network Function Virtualization) technology, load balancer, etc. may be performed as necessary. .

  If it is determined in S14 that priority is given to the reduction control by the air conditioner 35 (in the case of NO), the process moves to the flowchart of FIG. 4 and the arithmetic processing unit 61 determines whether or not a failure has occurred in the ICT device 25 or the like. Or processing for determining whether or not the operation will be hindered (S115). If it is determined that a failure has occurred or that the operation will be hindered (in the case of NO), the process for determining whether or not the degenerate operation is possible is stopped. In addition, since the specific processing content in this determination is the same as the determination in S15, the description is abbreviate | omitted.

  When it is determined that no failure has occurred (in the case of YES), the arithmetic processing unit 61 performs a process of determining whether or not the resources of the ICT device 25 have room (S116). When it is determined that there is no room for resources (in the case of NO), the process for determining whether or not the degenerate operation is possible is stopped. In addition, since the specific processing content in this determination is the same as the determination in S16, the description is abbreviate | omitted.

  When it is determined that there is a margin in resources (in the case of YES), the arithmetic processing unit 61 performs a process of determining whether or not there is a margin in the capacity of the power supply apparatus 10, the switch 16, or the switch 27A (S117). When it is determined that there is no capacity (NO), the process for determining whether or not the degenerate operation is possible is stopped. In addition, since the specific processing content in this determination is the same as the determination in S17, the description is abbreviate | omitted.

  When it is determined that there is a sufficient capacity (in the case of YES), the arithmetic processing unit 61 performs a process of determining whether there is a sufficient air conditioning capacity (S118). When it is determined that there is no room for air conditioning capability (in the case of NO), the process of determining whether or not the degenerate operation is possible is stopped. In addition, since the specific processing content in this determination is the same as the determination in S18, the description thereof is omitted.

  If it is determined that the air conditioning capacity is sufficient (in the case of YES), the integrated control device 60 outputs to the air conditioning control device 40 a command to stop the air conditioning device 35 that is estimated to have an excessive cooling capacity (S141). . In this embodiment, the description will be made by applying the present invention to an example in which the air conditioner 35 estimated to have an excessive cooling capacity is stopped. However, the present invention is not limited to the stop, and the control for reducing the power consumed by the air conditioner 35 is described. May be performed. Moreover, as a method for estimating that the cooling capacity is excessive, a known method can be used, and it is not particularly limited.

  Next, a process of determining whether or not the air conditioner 35 that is the target of the stop command is stopped is performed (S142). When it is determined that the target air conditioner 35 is not stopped (in the case of NO), the process for determining whether or not the degenerate operation is possible is stopped. In addition, since the specific processing content in this determination is the same as the determination in S42, the description thereof is omitted.

  Next, when it is determined that the air conditioner 35 is stopped (in the case of YES), the integrated control device 60 outputs a command to perform the aggregation process to the ICT control device 30. The ICT control device 30 outputs a command to execute an aggregation process for shifting to the degenerate operation to the target ICT device 25 (S121). Here, as the target ICT device 25, the ICT device 25 arranged in the cooling zone by the air conditioner 35 that is the target of the command to be stopped in the process of S141 can be exemplified. The contents of the aggregation process are the same as the contents of the process in S21, and thus the description thereof is omitted.

  Next, the integrated control device 60 performs a process of determining whether or not the ICT resource movement (Guest machine movement) is successful (S122). When it is determined that the movement of the ICT resource has failed (in the case of NO), the process for determining whether or not the degenerate operation is possible is stopped. In addition, since the specific processing content in this determination is the same as the determination in S22, the description is abbreviate | omitted.

  When it is determined that the ICT resource has been successfully moved (in the case of YES), the integrated control device 60 issues a pause instruction to the ICT control device 30 to the ICT device 25 that is the degeneration source, and pauses to the ICT device 25. A process of determining whether or not the process is successful is performed (S123). When it is determined that the pause of the ICT device 25 has failed (in the case of NO), the process of determining whether or not the degenerate operation is possible is stopped. In addition, since the specific processing content in this determination is the same as the determination in S23, the description thereof is omitted.

  When it is determined that the suspension of the ICT device 25 is successful (in the case of YES), the integrated control device 60 confirms the suspension state information of the ICT device 25 output from the ICT control device 30. After the confirmation, a stop (shutdown) command is issued to the ICT device 25 that has been stopped. After confirming that the ICT device 25 is stopped, the integrated control device 60 instructs the power supply control device 20 to turn off power to the outlet bar 27 on the power supply route, or to the switch 16 or the switch 27A of the current distribution device 15. Output (S31).

  Next, a process of determining whether or not the power supply is turned off in the switch 16 or the switch 27A corresponding to the stopped ICT device 25 is performed (S32). When it is determined that the power supply is not turned off (in the case of NO), the process for determining whether or not the degenerate operation is possible is stopped.

  Next, when it is determined that the power supply is turned off (in the case of YES), the integrated control device 60 outputs a command to stop the power supply unit 11 corresponding to the stopped ICT device 25 (S51).

  Next, a process of determining whether or not the power supply unit 11 corresponding to the stopped ICT device 25 is stopped is performed (S52). When it is determined that the power supply unit 11 is not stopped (in the case of NO), the process for determining whether or not the degenerate operation is possible is stopped.

  When it determines with the power supply unit 11 having stopped (in the case of YES), the integrated control apparatus 60 performs the process which outputs the instruction | command which turns off the illuminating device 45 (S61). Subsequently, the process which determines whether the illuminating device 45 was light-extinguished is performed (S62).

  When it is determined that the lighting device 45 is not turned off (in the case of NO), the process for determining whether or not the degenerate operation is possible is stopped. Moreover, when it determines with the illuminating device 45 having been extinguished (in the case of YES), the process which determines the propriety of degeneration operation is complete | finished.

  Next, a control process for executing restoration from the degenerate operation to the distributed operation will be described with reference to the flowchart of FIG. First, the acquisition unit 64 of the integrated control device 60 executes processing for acquiring entry / exit information from the entry / exit management device 65 (S211).

  When the entry / exit information is acquired, the arithmetic processing unit 61 of the integrated control device 60 determines whether the number of employees in the building in which the terminal of the ICT device 25 is provided is equal to or greater than a predetermined constant. Processing to determine whether or not is performed (S212). In the determination process of S212, when it is determined that the number of employees in the building is less than a predetermined number (in the case of NO), the arithmetic processing unit 61 stops the process of determining whether or not the distributed operation is possible. Note that the content of the determination in S212 is the same as the content of the process in S12, and thus the description thereof is omitted.

  On the other hand, when it is determined that the number of employees in the building is equal to or larger than a predetermined number (in the case of YES), the integrated control device 60 determines whether or not a failure has occurred in the ICT device 25 or the like. A process of determining whether or not the operation is hindered is performed (S213). Specifically, based on whether the monitoring control device 70 has received information indicating that an abnormality has occurred in the distribution source ICT device 25 and the distribution destination ICT device 25, the air conditioner 35, or the power supply device 10. The above-described determination process is performed.

  When it is determined that a failure has occurred or that the operation is hindered (in the case of NO), the process for determining whether or not to migrate is stopped. The distribution source ICT device 25 is the above-described degeneration destination ICT device 25, and the distribution destination ICT device 25 is the above-described degeneration source ICT device 25.

  When it is determined that no failure has occurred (in the case of YES), the integrated control device 60 performs a process of outputting a command for starting the air conditioner 35 related to the start target (S221). In other words, a command to start the operation for pre-cooling is output to the air-conditioning control device 40 that controls the air-conditioning device 35 in the air-conditioning zone of the ICT device 25 that resumes operation. The air conditioning control device 40 outputs a start command to the corresponding air conditioning device 35.

  Next, a process of determining whether or not the air conditioner 35 related to the activation target has been activated is performed (S222). When it is determined that the air conditioner 35 related to the activation target is not activated (in the case of NO), the process for determining whether or not to move is stopped.

  When it is determined that the air conditioner 35 related to the activation target is activated (in the case of YES), the integrated control device 60 performs a process of determining whether or not the temperature around the ICT device 25 is equal to or lower than a predetermined temperature. (S223). Examples of the temperature around the ICT device 25 include the air temperature around the ICT device 25 or the intake air temperature in the air conditioner 35. In this determination, specifically, it is determined whether or not the following two conditions are satisfied. The first is that no abnormality has occurred in the activated air conditioner 35. Second, the temperature in the vicinity of the suction portion of the ICT device 25 (or cold aisle) that is controlled by the activated air conditioner 35 is equal to or lower than a predetermined temperature. about.

  When it is determined that the temperature around the ICT device 25 is not lower than the predetermined temperature (in the case of NO), the determination in S223 is performed again. When it is determined that the temperature around the ICT device 25 is equal to or lower than the predetermined temperature (in the case of YES), the integrated control device 60 activates the power supply unit 11 that supplies power to the ICT device 25 that resumes operation. Processing to output a command is performed (S231). Specifically, a command for starting the power supply unit 11 is output to the power supply control device 20. The power supply control device 20 activates the power supply unit 11.

  Next, the integrated control device 60 performs processing for determining whether or not the power supply unit 11 has been activated (S232). The determination is made based on whether or not the following three conditions are satisfied. The first is that no abnormality has occurred in the power supply apparatus 10. Secondly, the power supply unit 11 has started up normally. Third, no abnormality has occurred in the power supply unit 11 even after startup. When it is determined that the power supply unit 11 is not activated (in the case of NO), processing for outputting an alert is performed.

  When it is determined that the power supply unit 11 is activated (in the case of YES), a process of outputting a command to turn on the switch 16 and the switch 27A is performed (S241). Specifically, a command to shift from the OFF state to the ON state is output to the switch 16 and the switch 27A located on the power supply path to the ICT device 25 that resumes operation to the power supply control device 20.

  Next, the integrated control device 60 performs a process of determining whether or not the switch 16 and the switch 27A have shifted to the ON state (S242). The determination is made based on whether or not the following three conditions are satisfied. The first is that no abnormality has occurred in the switch 16 and the switch 27A. Second, the outlets of the switch 16 and the switch 27A are normally turned on. No abnormality has occurred after the outlet is turned on. When it is determined that the switch 16 or the switch 27A remains in the OFF state (in the case of NO), processing for outputting an alert is performed.

  When it is determined that the switch 16 and the switch 27A have shifted to the ON state (in the case of YES), the integrated control device 60 performs a process of outputting a start command to the ICT device 25 (S251). The ICT control device 30 to which the command has been input performs a process of starting the ICT device 25 according to a startup procedure that matches the specifications of the ICT device 25. The integrated control device 60 continues to output a restoration process start instruction to the ICT control device 30 in order to shift from the degenerate operation to the distributed operation. The ICT control device 30 performs a process of shifting from the degenerate operation to the distributed operation state by following a procedure necessary for the distributed operation.

  Next, the integrated control device 60 performs processing for determining whether or not the ICT device 25 (Host machine) has been started (S252). The determination is made based on whether or not the following three conditions are satisfied. First, it is possible to connect to the target ICT device 25 using the management NW, and no abnormality has occurred. Second, it can be connected to the target ICT device 25 by a management NW and can be turned on. The third is to start up without any abnormality even after the power is turned on. When it is determined that the ICT device 25 is not activated (in the case of NO), processing for outputting an alert is performed.

  When it is determined that the ICT device 25 is activated (in the case of YES), the integrated control device 60 performs a process of determining whether or not the ICT resource movement (Guest machine movement) has been performed (S253). . The determination is made based on whether or not the following five conditions are satisfied. The first is that no H / W failure has occurred in the distributed ICT device 25 that is the switching (moving) ICT device 25. Second, there is no H / W failure in the distribution source ICT device 25 which is the switching (movement) source ICT device 25. Third, the virtual guest machine of the distribution source is normal on the virtualization management software. Fourth, the virtual guest machine to be moved is normal on the distribution source virtualization software. The fifth is that the ICT resource at the distribution destination has a margin. Specifically, the CPU usage rate is less than a predetermined value (for example, 80%), the memory usage rate is less than a predetermined value (for example, 80%), and the usage rate of the hard disk (HDD) is a predetermined value ( For example, less than 80%).

  When it is determined that the ICT resource has not been moved (in the case of NO), processing for outputting an alert is performed. When it is determined that the ICT resource has been moved (in the case of YES), the integrated control device 60 performs a process of outputting a command to turn on the lighting device 45 (S261).

  Next, the integrated control device 60 performs a process of determining whether or not the lighting device 45 is turned on (S262). The determination is made based on whether or not the power supply device 10, the ICT device 25, and the air conditioner 35 are normally activated and no abnormality has occurred.

  When it is determined that the lighting device 45 is not turned on (in the case of NO), processing for outputting an alert is performed. When it is determined that the lighting device 45 is turned on (in the case of YES), the process for executing restoration from the degenerate operation to the distributed operation is ended.

  In the restoration process for shifting from the degenerate operation to the distributed operation, network control and load control such as SDN (software defined network) technology, NFV (Network Function Virtualization) technology, load balancer, and the like may be performed as necessary. Also, if an unnecessary alarm occurs during the transition process, it is possible to take measures to temporarily mask the alarm.

  According to the power supply system 1 having the above-described configuration, the information processing amount such as calculation in the ICT device 25 is estimated based on the acquired employee entry / exit information and information such as the ICT device 25, and information processing such as the estimated calculation is performed. According to the amount, the power consumption by the ICT device 25 and the power consumption by the air conditioner 35 can be prioritized to reduce the overall power consumption. Therefore, for example, priority is not given to reduction by the ICT device 25 and reduction by the air conditioner 35, and it is easy to secure a reduction amount of power consumption compared to a case where each reduces power consumption without being linked. Become. Or it becomes easy to aim at reduction of power consumption, suppressing the influence which it has on information processing, such as calculation in the ICT apparatus 25. FIG.

  By making the priority of reduction by the ICT device 25 higher than the reduction by the air conditioner 35, it is possible to reduce power consumption while suppressing the influence on the information processing such as calculation in the ICT device 25. In general, the power consumption in the ICT device 25 is related to information processing such as computation in the ICT device 25. Therefore, by giving priority to the reduction by the ICT device 25, it becomes easy to achieve a balance between the influence on the information processing such as calculation in the ICT device 25 and the reduction of power consumption.

  By further reducing the power consumption in the power supply apparatus 10, it becomes easier to increase the amount of power consumption compared to the case where only the reduction by the ICT apparatus 25 and the reduction by the air conditioner 35 are performed.

  Furthermore, the priority of reduction by the air conditioner 35 and reduction by the ICT device 25 is set higher than the reduction in the power supply device 10, so that it becomes easy to secure a reduction in power consumption. That is, in the information communication equipment, paying attention to the air conditioner 35 that consumes the second most power after the ICT device 25, and prioritizing the reduction judgment process by more efficient operation over the reduction judgment by the ICT device 25, the power consumption can be reduced. It becomes easy to secure the amount.

  By including employee entry / exit information and information of the ICT device 25 in the parameters, it becomes easy to estimate the amount of information processing such as computation in the ICT device 25. For example, when an employee enters a building where a terminal for using the ICT device 25 is placed, it is considered that the employee is likely to use the ICT device 25. Therefore, based on these pieces of information, it becomes easy to estimate the amount of information processing such as computation in the ICT device 25. Further, even if the use status of the ICT device 25 by the employee is the same, the amount of information processing such as computation in the ICT device 25 differs depending on the type of the ICT device 25 and the status of information processing amount such as other computations. Conceivable. Therefore, based on these pieces of information, it becomes easy to estimate the amount of information processing such as computation in the ICT device 25.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIG. The basic configuration of the power supply system of this embodiment is the same as that of the first embodiment, but the control in the power supply system is different from that of the first embodiment. Therefore, in this embodiment, different control will be described using FIG. 7, and description of the configuration of the power feeding system and the like will be omitted.

  Control in the power supply system 1 of the present embodiment will be described. In the present embodiment, a description will be given of the integrated linkage control of the power feeding system 1 based on information on employee position information, employee schedule information, employee seat information, ICT device 25, and the like.

  Specifically, the control process when executing the degenerate operation will be described with reference to the flowchart of FIG. First, the acquisition unit 64 of the integrated control device 60 executes a process of acquiring employee position information from the storage unit 66 (S311: acquisition step). Subsequently, the process which acquires additional information is performed (S312: acquisition step). Here, the additional information can exemplify employee schedule information, employee seat information, and ICT resource information stored in the storage unit 67.

  Upon acquiring these pieces of information, the integrated control device 60 performs a process of determining whether or not there is an effect of reducing power consumption when the degenerate operation is executed (S313). When it is determined that there is no power consumption reduction effect (in the case of NO), the arithmetic processing unit 61 stops the process of determining whether or not the degenerate operation is possible.

  Note that the effect of reducing the power consumption is determined based on the above-described employee position information, employee schedule information, employee seat information, and ICT resource information. For example, based on the position information of the employee and the seat information of the employee, it is estimated whether or not the employee is seated. When the employee is seated, the ICT device 25 performs information processing such as calculation. It can be estimated that there is a high possibility of being required.

  Further, based on the schedule information of the employee, it is possible to estimate whether the employee uses the ICT device 25 during the time period, and when the ICT device 25 is used, the amount of information processing such as calculation can be estimated. Based on the information processing amount such as the estimated calculation and the ICT resource information, the operating rate of the ICT device 25 can be estimated. Based on such estimation, it can be determined whether or not there is an effect of reducing power consumption when the degenerate operation is executed.

  When it is determined that there is an effect of reducing power consumption (in the case of YES), the arithmetic processing unit 61 performs processing for determining the priority of control (S314: priority processing step). In the present embodiment, processing for determining the priority between the reduction control by the ICT device 25 and the reduction control by the air conditioner 35 is performed. Specifically, a process for determining whether or not the reduction control by the ICT device 25 has priority over the reduction control by the air conditioner 35 is performed.

  The prediction processing unit 63 performs calculation processing for estimating an information processing amount such as calculation in the ICT device 25 based on employee position information, employee schedule information, employee seat information, and ICT resource information. When the amount of information processing such as the estimated calculation increases, the calculation processing unit 61 determines that priority is given to reduction control by the ICT device 25 (YES). On the other hand, if the amount of information processing such as the estimated calculation does not increase, it is determined that priority is given to reduction control by the air conditioner 35 (NO).

  If it is determined in S314 that priority is given to the reduction control by the ICT device 25 (in the case of YES), the arithmetic processing unit 61 determines whether or not a failure has occurred in the ICT device 25 or the like, or hinders operation. The process which determines whether or not is performed (S15). Since the subsequent control is the same as that of the first embodiment, the flowchart is shown in FIG. 7 and the description thereof is omitted. Moreover, since it is the same as that of 1st Embodiment also about the subsequent control in the case of determining with priority to the reduction control by the air conditioner 35 in determination of S314 (in the case of NO), the description is abbreviate | omitted. .

  According to the power supply system 1 having the above configuration, it is easy to estimate the amount of information processing such as computation in the ICT device 25 by including schedule information and calendar information as parameters. For example, the employee of the ICT device 25 may tend to use the ICT device 25 on weekdays and not to use the ICT device 25 on holidays or holidays. Further, the ICT device 25 may be used according to the schedule of the organization to which the employee belongs. The usage frequency of 25 may vary. Based on such circumstances, it becomes easy to estimate the amount of information processing such as computation in the ICT device 25.

  By making the parameters position information and seat position information of the employee, it becomes easy to estimate the amount of information processing such as calculation in the ICT device 25. For example, when the position of the employee is in the vicinity of the seat position where the use terminal of the ICT device 25 is arranged, it is considered that the employee is likely to use the ICT device 25. Therefore, based on these pieces of information, the workload amount in the ICT device 25 can be easily estimated.

[Third Embodiment]
Next, a third embodiment of the present invention will be described with reference to FIG. The basic configuration of the power supply system of the present embodiment is the same as that of the first embodiment, but the control in the power supply system is different from that of the first embodiment. Therefore, in the present embodiment, different control will be described using FIG. 8 and description of the configuration of the power feeding system and the like will be omitted.

  Control in the power supply system 1 of the present embodiment will be described. In the present embodiment, the integrated linkage control of the power feeding system 1 based on information such as traffic information, employee schedule information, entry / exit information, and the ICT device 25 will be described.

  Specifically, the control process when executing the degenerate operation will be described with reference to the flowchart of FIG. First, the acquisition unit 64 of the integrated control device 60 executes a process of acquiring traffic information from the storage unit 68 (S411). Examples of the traffic information acquired here include delay information announced by public transportation such as a railway company and a bus company.

  Next, the acquisition unit 64 executes a process of acquiring employee schedule information from the storage unit 67 (S412). Further, a process of acquiring employee entry / exit information from the entry / exit management device 65 is executed (S413), and a process of acquiring ICT resource information is executed (S414).

  When these pieces of information are acquired, the arithmetic processing unit 61 of the integrated control device 60 performs processing for determining whether or not there is an effect of reducing power consumption when the degenerate operation is executed (S415). When it is determined that there is no power consumption reduction effect (in the case of NO), the arithmetic processing unit 61 stops the process of determining whether or not the degenerate operation is possible. When it is determined that there is an effect of reducing power consumption (in the case of YES), the arithmetic processing unit 61 continues the control process for executing the degenerate operation (S416).

  The power consumption reduction effect is determined based on the above-described traffic information (for example, delay information), employee schedule information, entry / exit information, ICT device 25, and the like. For example, based on the delay information, it is estimated whether or not the employee is working at the start time. When the employee is at the start time, information processing such as calculation is required in the ICT device 25. It can be estimated that the possibility is high. Further, based on the schedule information of the employee, even if the start time of the employee is irregular, it can be suppressed that the estimation accuracy of the possibility that information processing such as calculation is required in the ICT device 25 is deteriorated. . Based on the information processing amount such as the estimated calculation and the ICT resource information, the operating rate of the ICT device 25 can be estimated. Based on such estimation, it can be determined whether or not there is an effect of reducing power consumption when the degenerate operation is executed.

  According to the power supply system 1 having the above-described configuration, the information processing amount such as the calculation in the ICT device 25 can be easily estimated by using the parameter as traffic information. For example, when it is difficult to secure transportation means due to a delay or the like, it is predicted that it is difficult for the user of the ICT device 25 to go to work, and it is estimated that the amount of information processing such as computation in the ICT device 25 decreases. Is done.

In this embodiment, regarding the integrated linkage control of the power feeding system 1 based on weather information and information such as the ICT device 25, it is further determined whether to continue the distributed operation.

  Specifically, a control process for determining whether to continue the distributed operation will be described with reference to the flowchart of FIG. First, the acquisition unit 64 of the integrated control device 60 executes a process of acquiring weather information from the storage unit 68 (S511). Examples of the weather information acquired here include various special warnings announced by the Japan Meteorological Agency. Next, the acquisition unit 64 executes processing for acquiring ICT resource information and alarm information (S512).

  When these pieces of information are acquired, the arithmetic processing unit 61 of the integrated control device 60 performs a process of determining whether there is no problem when the distributed operation is continued (S513). The acquired weather information and information such as the ICT device 25 are used when estimating the information processing amount such as the calculation used when performing the determination process in S513. In addition, as determination of whether there is no problem, for example, a series of determinations from S14 to S18 in the first embodiment can be cited.

  When it is determined that there is a problem in the determination in S513 (in the case of NO), the arithmetic processing unit 61 stops the process of determining whether or not to continue the distributed operation. When it is determined that there is no problem (in the case of YES), the arithmetic processing unit 61 continues the control process for continuing the distributed operation (S514).

[Fifth Embodiment]
Next, a fifth embodiment of the present invention will be described with reference to FIG. The basic configuration of the power supply system of the present embodiment is the same as that of the first embodiment, but the control in the power supply system is different from that of the first embodiment.

Furthermore, a process of acquiring employee entry / exit information from the entry / exit management device 65 is executed (S613), and a process of acquiring ICT resource information is executed (S614).

  When these pieces of information are acquired, the arithmetic processing unit 61 of the integrated control device 60 performs a process of determining whether there is no problem by continuing the distributed operation (S615). When it is determined that there is a problem by continuing the distributed operation (in the case of NO), the arithmetic processing unit 61 stops the process for determining the continuation of the distributed operation. When it is determined that there is no problem by continuing the distributed operation (in the case of YES), the arithmetic processing unit 61 continues the control process for executing the degenerate operation (S616).

  According to the power feeding system 1 having the above configuration, it is easy to estimate the amount of information processing such as computation in the ICT device 25 by including weather information as a parameter. For example, in the case of bad weather such as when a special warning is announced, it is predicted that it is difficult for employees who use the ICT device 25 to go to work, and the amount of information processing such as calculations in the ICT device 25 may decrease. Presumed.

[Sixth Embodiment]
Next, a sixth embodiment of the present invention will be described with reference to FIG. The basic configuration of the power supply system of the present embodiment is the same as that of the first embodiment, but the control in the power supply system is different from that of the first embodiment. Therefore, in the present embodiment, different control will be described using FIG. 11 and description of the configuration of the power feeding system and the like will be omitted.

  Control in the power supply system 1 of the present embodiment will be described. In the present embodiment, regarding the integrated linkage control of the power feeding system 1 based on weather information, traffic information, employee schedule information, entrance / exit information, and information such as the ICT device 25, it is further determined whether or not to continue the reduced operation. Is called.

  Specifically, a control process for determining whether to continue the degenerate operation will be described with reference to the flowchart of FIG.

Furthermore, the process which acquires the employee's entrance / exit information from the entrance / exit management apparatus 65 is performed (S714), and the process which acquires ICT resource information and alarm information is performed (S715).

  When these pieces of information are acquired, the arithmetic processing unit 61 of the integrated control device 60 performs a process of determining whether or not there is a problem when the degenerate operation is executed (S716). Information such as the acquired weather information, traffic information, employee schedule information, entrance / exit information, and the ICT device 25 is used when estimating the amount of information processing such as computation used when performing the determination process in S716. In addition, as determination of whether there is no problem, for example, a series of determinations from S14 to S18 in the first embodiment can be cited.

  When it is determined that there is a problem in the determination in S716 (in the case of NO), the arithmetic processing unit 61 stops the process of determining whether or not the degenerate operation is possible. When it is determined that there is no problem (in the case of YES), the arithmetic processing unit 61 continues the control process for executing the degenerate operation (S717).

[Seventh Embodiment]
Next, a seventh embodiment of the present invention will be described with reference to FIGS. The basic configuration of the power supply system of this embodiment is the same as that of the first embodiment, but the control in the power supply system is different from that of the first embodiment. Therefore, in this embodiment, different control is demonstrated using FIG. 12 and FIG. 13, and description, such as a structure of an electric power feeding system, is abbreviate | omitted.

  Here, the control which is the characteristic of the electric power feeding system 1 of this embodiment is demonstrated. The present embodiment is different from the other embodiments described above in that a process for determining the priority order of which one of the ICT device priority mode and the air conditioning priority mode is prioritized is further performed.

  First, the control process when executing the degenerate operation will be described with reference to FIG. When the control process is started, the integrated control device 60 performs a process of determining the control priority (S800). Specifically, the subroutine processing shown in FIG. 13 determines whether to select either the ICT device priority mode that prioritizes the reduction control by the ICT device 25 or the air conditioning priority mode that prioritizes the reduction control by the air conditioning device 35. To do.

  Details of the subroutine processing for determining the control priority will be described with reference to FIG. When the processing of the subroutine is started, the acquisition unit 64 of the integrated control device 60 performs processing for acquiring information (S801). Examples of the information acquired here include load factor information of the ICT device 25, power consumption information and position information, and operation information of the air conditioner 35.

  When the information is acquired, the arithmetic processing unit 61 performs a process of calculating a load factor for each air conditioning zone (S802). The air conditioning zone is an area where the room temperature is adjusted by the air conditioner 35. The air conditioning zone changes according to the arrangement of the air conditioner 35 and the ICT device 25, the wind speed, the air volume, the direction of the air blown from the air conditioner 35, and the like. In the present embodiment, description will be made by applying to an example in which each air conditioner 35 is measured and the air conditioning zone is grasped in advance.

  In the present embodiment, a method for calculating a load factor will be described by applying it to an example described below. That is, the load factor for each air conditioning zone is calculated based on the load factor information of the ICT device 25 associated with each air conditioning zone by associating the ICT device 25 with each air conditioning zone based on the position information. The load factor for each air conditioning zone may be an average value based on the load factor information of a plurality of ICT devices 25 linked to the air conditioning zone, or may be other than the median value, mode value, maximum value, minimum value, etc. It may be a value of and is not particularly limited.

  When the load factor for each air conditioning zone is calculated, the arithmetic processing unit 61 performs a process of determining whether or not a low load zone exists (S803). In the present embodiment, description will be made by applying to an example in which it is determined whether or not a low load zone exists by comparing a threshold value of a predetermined load factor with a load factor for each air conditioning zone.

  If it is determined in the determination process of S803 that there is no low load zone (in the case of NO), the arithmetic processing unit 61 performs a process of setting the ICT device priority mode (S804). Thereafter, the subroutine processing by the arithmetic processing unit 61 ends, and the processing shifts to the flowchart of FIG.

  When it is determined in the determination process of S803 that a low load zone exists (in the case of YES), the arithmetic processing unit 61 transfers the load process from the ICT device 25 in the low load zone to the ICT device 25 in the other zone. Processing for determining whether or not is possible is performed (S805).

  The specific contents of the determination processing performed here are determination processing for determining whether or not a failure has occurred in the ICT device 25 or the like of S15 in the first embodiment, or whether or not the operation will be hindered, Processing for determining whether or not the resources of the ICT device 25 have a margin, processing for determining whether or not the capacity of the power supply device 10, the switch 16, and the switch 27A in S17 is sufficient, and whether or not the air conditioning capability in S18 has margin Since this is the same as the determination processing, the description thereof is omitted.

  In the determination process of S805, when it is determined that the shift of the load process is possible (in the case of YES), the arithmetic processing unit 61 performs a process of determining whether or not the power consumption is reduced by this shift ( S806). Specifically, the power consumed when the load processing is continued in the ICT device 25 located in the low load zone and the load processing are transferred to the ICT device 25 located in the other zone, and the load processing is performed. The determination is performed by calculating the power consumed when performing the above and comparing the values of both powers.

  In the determination process of S806, when it is determined that the power consumption is reduced (in the case of YES), the arithmetic processing unit 61 performs a process of setting the air conditioning priority mode (S807). Thereafter, the subroutine processing by the arithmetic processing unit 61 ends, and the processing shifts to the flowchart of FIG.

  In the determination process of S805, when it is determined that the load process cannot be shifted (in the case of NO), or in the determination process in S806, it is determined that the power consumption does not decrease (in the case of NO). The arithmetic processing unit 61 performs processing to determine whether or not load processing can be transferred from the ICT device 25 in the other zone described above to the ICT device 25 in the low load zone (S808).

  When it is determined in the determination process of S808 that the load can be shifted (in the case of YES), the arithmetic processing unit 61 performs a process of determining whether or not the power consumption after the shift is reduced (S809). Specifically, the power consumed when the load processing is continued in the ICT device 25 located in another zone and the load processing are transferred to the ICT device 25 located in the low load zone, and the load processing is performed. The determination is performed by calculating the power consumed when performing the above and comparing the values of both powers.

  In the determination process of S809, when it is determined that the power consumption after the transition decreases (in the case of YES), the arithmetic processing unit 61 loads the load from the ICT device 25 in the other zone to the ICT device 25 in the low load zone. (S810) and a process for setting the air conditioning priority mode (S807). Thereafter, the subroutine processing by the arithmetic processing unit 61 ends, and the processing shifts to the flowchart of FIG.

  When it is determined in the determination process in S808 that the load process cannot be shifted (in the case of NO), or in the determination process in S809, it is determined that the power consumption after the shift does not decrease (in the case of NO) ), The arithmetic processing unit 61 performs processing for setting the ICT device priority mode (S804). Thereafter, the subroutine processing by the arithmetic processing unit 61 ends, and the processing shifts to the flowchart of FIG.

  When the subroutine processing is completed and the processing returns to the flowchart of FIG. 12, the arithmetic processing unit 61 performs processing to determine whether or not the mode set in the subroutine is the ICT device priority mode (S821). When it is determined that the setting is the ICT device priority mode (in the case of YES), the processing in the arithmetic processing unit 61 proceeds to the processing of S11, and thereafter, the same processing as in the first embodiment is performed.

  When it is determined in the determination process of S821 that the setting is not the ICT device priority mode (in the case of NO), the arithmetic processing unit 61 determines whether or not the mode set in the subroutine is the air conditioning priority mode. (S822). When it is determined that the setting is the air conditioning priority mode (in the case of YES), the processing of the arithmetic processing unit 61 proceeds to the processing of S115, and thereafter, the same processing as that of the first embodiment is performed.

When it is determined that the setting is not the air conditioning priority mode (in the case of NO), the arithmetic processing unit 61 stops the process of determining whether or not the degenerate operation is possible.
In addition, like the above-mentioned embodiment, you may perform the process (S800) which determines a control priority after a control process is started, or as shown in FIG. 14, the process (S11 which acquires entrance / exit information) ) And the process of determining the control priority (S800) may be performed after it is determined that the number of employees is less than a predetermined fixed number (YES in S12). In this case, when the setting is determined to be the ICT device priority mode in the determination process of S821 (YES), the process in the arithmetic processing unit 61 proceeds to the process of S15, and thereafter, the same process as in the first embodiment is performed. .

  According to the power supply system 1 having the above-described configuration, control is performed based on the determination result as to which of the ICT device priority mode and the air conditioning priority mode is prioritized, so that power consumption can be easily reduced. For example, when there is an ICT device 25 with a low load factor of the ICT device 25, the air conditioner 35 is operated in a low load state or the air blowing operation and the cooling operation are repeated, so that it is difficult to reduce power consumption. It becomes. In this case, by adopting the air conditioning priority mode, it becomes easier to reduce the power consumption than when the ICT device priority mode is adopted.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the above embodiment, the description is applied to an example in which the power supply control device 20, the ICT control device 30, the air conditioning control device 40, the lighting control device 50, and the integrated control device 60 are provided. However, some control devices may be combined into one control device (server), or all control devices may be combined into one control device (server), which is particularly limited. It is not a thing.
