[Configuration of seat aggregation system]
Next, the configuration of the seat aggregation device 10 shown in FIG. 1 will be described with reference to FIG. FIG. 2 is a block diagram illustrating the configuration of the seat aggregation device according to the second embodiment. As shown in FIG. 2, the seat aggregating apparatus 10 includes an operating number storage unit 11, a floor information storage unit 12, an aggregation result storage unit 13, a used power collection unit 14, an operating number calculation unit 15, a number determination unit 16, and an aggregation determination. Unit 17, aggregation notification unit 18, and power supply control unit 19. The processing of each of these units will be described below.

  The operating number storage unit 11 stores area units and operating PC numbers for each time zone. Specifically, as illustrated in FIG. 4, the operating unit storage unit 11 includes areas 1 to 4, PC-1 to PC-12 belonging to any of the areas 1 to 4, and 7: 0 to 19: 55 stores the power usage of each PC terminal (PC-1 to PC-12) in 55 and the number of operating devices in all areas in each time zone. For example, PC-1 installed in area 1 has a power consumption of 11:00 of 50.1 watts. Also, for example, at 11:00, PC-1, PC-2, PC-3 in area 1, PC-6 in area 2, PC-7, PC-8 in area 3, PC-11 in area 4 Is in operation and the number of units in operation will be "7 units".

  The floor information storage unit 12 stores a list of power devices for each area and the power usage of each power device. Specifically, as shown in FIG. 5A, the floor information storage unit 12 sets “steady value”, which is a steady power consumption amount of the power equipment, for the “installed equipment” in each area. “Start-up” that is the amount of power to be used and “Shutdown” that is the amount of power to be used when shutting down are stored. For example, the steady value of the illumination-1 installed in the area 1 is “40” watts, and the steady value of the air conditioner-1 installed in the area 1 is “120” watts. Further, the amount of power used when the PC-1 installed in the area 1 is started is “7” watts, and the amount of power used when the PC-1 is shut down is “2” watts.

  Further, as shown in FIG. 5B, the floor information storage unit 12 stores area aggregation availability information indicating whether each area can be aggregated or not aggregated. For example, as illustrated in FIG. 5B, the areas 1 to 4 can be aggregated, but the area 5 cannot be aggregated. The area where aggregation is impossible is an area where the power of the power device cannot be turned off or an area where the user of the power device does not want to move, for example, a classroom where an experiment is performed or an office used by general affairs.

  The aggregation result storage unit 13 stores the number of PCs operating for each area before aggregation and the number of PCs scheduled to operate for each area after aggregation. Specifically, as shown in FIG. 6, the aggregation result storage unit 13 includes the number and power amount of PCs operating for each area before aggregation, and the number and power of PCs scheduled to operate for each area after aggregation. Quantity, the number of lightings reduced when consolidating and the amount of power reduced, the number of air conditioning reduced when consolidating and the amount of power reduced, the expected reduction when consolidating The total power amount to be processed and the aggregation determination indicating whether or not the aggregation is determined in the aggregation determination process (see FIG. 13 and the like) described later are stored.

  For example, in the example of FIG. 6, the aggregation result storage unit 13 operates in the area 1 before the aggregation, three in the area 2, three in the area 3, one in the area 3, and two in the area 4. It is stored that 12 units are scheduled to operate only in area 1. In the example of FIG. 6, as a result of the aggregation of the PCs operating in the area 1, the aggregation result storage unit 13 has 0 PCs in the areas 2 to 4 and one PC is installed in each of the areas 2 to 4. In addition, it is stored that the power consumption of a total of three lighting devices and air conditioning facilities is to be reduced, and that the power consumption of “120” watts and “420” watts is to be reduced, respectively. In addition, it is stored that the value of the used power to be reduced is “486” watts and the aggregation determination is “good”, that is, it is determined that the aggregation is performed in the aggregation determination process.

  The above-mentioned operating number storage unit 11, floor information storage unit 12, and aggregation result storage unit 13 are a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, a hard disk, an optical disk, or the like. Storage device.

  The power usage collection unit 14 collects the power usage of each PC installed in each area. Specifically, the power usage collection unit 14 collects the power usage of each PC installed in each area at an interval of one hour. In addition, the used power collecting unit 14 is installed in each area at intervals of 5 minutes when the later-described number determining unit 16 determines that the current number of operating PCs is less than the previous number of operating PCs. Collect the power usage of each PC.

  The operating number calculation unit 15 determines whether each PC is operating using the power usage of each PC collected by the used power collecting unit 14, and calculates the operating number of PCs in all areas. . Specifically, the operating number calculation unit 15 determines whether the power usage of each PC collected by the used power collection unit 14 is equal to or greater than a predetermined threshold (for example, 20 watts), and the power usage of the PC is 20 If it is greater than or equal to watts, it is determined that each PC is operating. Then, the number of PCs whose PC power usage is 20 watts or more is counted. In addition, when the used power collecting unit 14 collects the power usage amount of each PC at intervals of 5 minutes, the operating number calculating unit 15 determines whether each PC is operating, and in all areas The number of operating PCs is calculated every five minute intervals, and the average value of the number of operating PCs every five minute intervals within one hour interval is calculated.

  The number determination unit 16 compares the current PC operation number calculated by the operation number calculation unit 15 with the previous PC operation number, and the current PC operation number is smaller than the previous PC operation number. It is determined whether or not. In addition, when the average value of the number of operating PCs at every five minute interval within one hour interval is calculated by the operating number calculating unit 15, the number determining unit 16 calculates the average value calculated by the operating number calculating unit 15. And the previous number of operating PCs are compared to determine whether the average value of the number of operating PCs is smaller than the previous number of operating PCs.

  When the number determining unit 16 determines that the current number of operating PCs is smaller than the previous number of operating PCs, the aggregation determining unit 17 calculates the number of operating PCs calculated by the operating number calculating unit 15; Based on the number of installed PCs in each area, it is determined whether or not the number of areas in which all PCs in the area are not operating can be increased when operating PCs are aggregated into a specific area. To do.

  Specifically, the aggregation determination unit 17 sequentially subtracts the number of installed PCs in an area with a high priority from the number of operating PCs in the area calculated by the operating unit calculating unit 15, and The number of installed PCs is sequentially stored in the aggregation result storage unit 13 as the number of PCs scheduled to operate after aggregation in the area, and the number of PCs scheduled to operate for each area after aggregation stored in the aggregation result storage unit 13 is calculated. It is determined whether or not the number of areas where all the PCs in the area are not operating can be increased. Here, the priority order is an order of areas in which PCs are preferentially aggregated, and may be set in advance or may be set every time.

  When the aggregation determination unit 17 determines that the number of areas where all the PCs in the area are not operating can be increased, the power that can be reduced by aggregating the PCs in the area into the specific area is reduced to the area. It is determined whether or not it is larger than the power required to consolidate the PCs in a specific area.

  When the aggregation notifying unit 18 determines that the number of areas in which all the PCs in the area are not operating can be increased by the aggregation determining unit 17, an instruction for consolidating the operating PCs into a specific area is given. Output. Specifically, the aggregation notification unit 18 determines that the number of areas where all the PCs in the area are not operating can be increased by the aggregation determination unit 17 and aggregates the PCs in the area into a specific area. If it is determined that the power that can be reduced is greater than the power required to consolidate the PCs in the area into a specific area, the operation is scheduled for each area after aggregation stored in the aggregation result storage unit 13. According to the number of PCs, an instruction to move the area is output to the PC user.

  If the power supply control unit 19 determines that the number of areas in which all PCs in the area are not operating can be increased by the aggregation determination unit 17, the electrical equipment in the area in which all PCs are not operating due to the aggregation And turn on the electrical equipment in the aggregation destination area.

  Here, the aggregation process which the seat aggregation apparatus 10 performs is demonstrated using the example of FIG. FIG. 7 is a diagram for explaining an example of the aggregation processing. As illustrated in FIG. 7, the seat aggregating apparatus 10 starts processing from 7:00 and calculates the operation of the PC in all areas at an interval of one hour. Then, the seat aggregating apparatus 10 compares the current number of operating PCs with the previous number of operating PCs, and determines whether the current number of operating PCs is smaller than the previous number of operating PCs. In the example of FIG. 7, the seat aggregating apparatus 10 determines that the number of operating PCs “4” at 12:00 is less than the number of operating PCs “7” at 11:00. Here, the seat aggregation device 10 calculates the number of operating PCs in all areas at intervals of 5 minutes between 12: 00 and 12: 55, and every 5 minutes between 12: 00 and 12: 55. The average value of the number of operating PCs is calculated.

  Then, the seat aggregating apparatus 10 compares the average value of the number of operating PCs at intervals of 5 minutes between 12:00 and 12:55 with the number of operating PCs at 11:00, and 12:00 to 12 : It is determined whether or not the number of operating PCs every 5 minutes up to 55 is smaller than the number of operating PCs at 11:00. In the example of FIG. 7, the average value “9.0” of the number of operating PCs every 5 minutes between 12:00 and 12:55 is “9.0”, which is larger than the number of operating PCs “7” at 11:00. Because there are many, aggregation processing is not performed.

  Subsequently, the seat aggregating apparatus 10 similarly determines that the number of operating PCs “10” at 14:00 is smaller than the number of operating PCs “12” at 13:00. For this reason, the seat aggregation device 10 calculates the number of operating PCs in all areas at intervals of 5 minutes between 14: 00 and 14: 55, and every 5 minutes between 14: 00 and 14: 55. The average value of the number of operating PCs is calculated. Then, the seat aggregating apparatus 10 compares the average number of operating PCs at intervals of 5 minutes between 14:00 and 14:55 with the operating number of PCs at 13:00. In the example of FIG. 7, the average value “10.6” of the number of operating PCs at intervals of 5 minutes between 14:00 and 14:55 is greater than the number of operating PCs “12” at 13:00. Few.

  In this case, the seat aggregating apparatus 10 determines whether or not the number of areas in which all PCs in the area are not operating can be increased when operating PCs are aggregated into a specific area. In the example of FIG. 7, 11 units are operating at 14:55, and even if the operating PCs are aggregated into a specific area, any of areas 1 to 4 should be an area where no PC is operating. Therefore, the aggregation process is not performed because there is no area that can be aggregated.

  Subsequently, the seat aggregating apparatus 10 similarly determines that the number of operating PCs “7” at 16:00 is less than the number of operating PCs “1” at 15:00. Therefore, the seat aggregation device 10 calculates the number of operating PCs in all areas at intervals of 5 minutes between 16: 00 and 16: 55, and every 5 minutes between 16: 00 and 16: 55. The average value of the number of operating PCs is calculated. Then, the seat aggregating apparatus 10 compares the average number of operating PCs at intervals of 5 minutes between 16:00 and 16:55 with the operating number of PCs at 15:00. In the example of FIG. 7, it is the average value “9.3” of the number of operating PCs every 5 minutes between 16:00 and 16:55, which is more than the operating number of PCs “10” at 15:00. Few.

  In this case, the seat aggregating apparatus 10 determines whether or not the number of areas in which all PCs in the area are not operating can be increased when operating PCs are aggregated into a specific area. In the example of FIG. 7, 11 units are operating at 16:55, and even if the operating PCs are aggregated into a specific area, all of the areas 1 to 4 should be areas where PCs are not operating. Therefore, the aggregation process is not performed because there is no area that can be aggregated.

  Subsequently, the seat aggregating apparatus 10 similarly determines that the number of operating PCs “5” at 19:00 is smaller than the number of operating PCs “1” at 18:00. For this reason, the seat aggregating apparatus 10 calculates the number of PCs operating in all areas at intervals of 5 minutes between 19: 00 and 19: 55, and every 5 minutes between 19: 00 and 19: 55. The average value of the number of operating PCs is calculated. Then, the seat aggregating apparatus 10 compares the average number of operating PCs every 5 minutes between 19:00 and 19:55 with the operating number of PCs at 18:00. In the example of FIG. 7, the average value “5.0” of the number of operating PCs every 5 minutes between 19:00 and 19:55 is “5.0”, which is larger than the number of operating PCs “11” at 18:00. Few.

  In this case, the seat aggregating apparatus 10 determines whether or not the number of areas in which all PCs in the area are not operating can be increased when operating PCs are aggregated into a specific area. In the example of FIG. 7, 5 units are operating at 19:55, and the operating PCs can be aggregated into a specific area so that the PCs are not operating. A process for aggregating PCs that are in operation. Here, the number of operating units in area 1 is 0, the number of operating units in area 2 is 1, the number of operating units in area 3 is 2, the number of operating units in area 4 is 2, and priority is given to areas with many operating units. In order to reduce the movement of users by aggregating operating PCs, the users in area 2 are moved to area 3 to perform aggregation processing.

  In this way, since the users in area 2 are moved to area 3 and the PCs operating in areas 3 and 4 are aggregated, the air conditioning equipment and lighting in area 2 can be turned off, and the amount of power used Can be reduced.

  Here, with reference to FIG. 8, power saving by consolidating operating PCs will be described. FIG. 8 is a diagram for explaining power saving by the aggregation processing. In the example of FIG. 8, 12 PCs are installed in areas 1 to 4, and air conditioning equipment and lighting are further provided. Before consolidation, the number of operating PCs in area 1 is 6, the number of operating PCs in area 2 is 3, the number of operating PCs in area 3 is 1, and the number of operating PCs in area 4 is 2.

  In the example of FIG. 8, twelve PC operating numbers in all areas are aggregated in area 1 and the PC operating numbers in areas 2 to 4 are set to zero. By setting the number of PCs operating in areas 2 to 4 to zero, the power to the PCs in areas 2 to 4 can be turned off, and the air conditioning equipment and lighting in areas 2 to 4 can be turned off. As a result, it is possible to reduce the power consumption.

  Here, the configuration of the power supply monitoring apparatus 20 will be briefly described with reference to FIG. FIG. 3 is a block diagram illustrating the configuration of the power supply monitoring apparatus according to the first embodiment. As illustrated in FIG. 3, the power supply monitoring device 20 includes a power supply unit 21, a power supply control unit 22, a power consumption measurement unit 23, and a power consumption notification unit 24.

  The power supply unit 21 supplies power to each electrical device such as a connected PC. The power supply control unit 22 controls power supply to each electrical device such as a connected PC or stop of power supply. The power consumption measuring unit 23 measures the amount of power supplied to each connected electrical device. The power consumption notification unit 24 notifies the seat aggregation device 10 of the amount of power supplied to each connected electrical device.

[Processing by seat aggregator]
Next, processing performed by the seat aggregation device 10 according to the first embodiment will be described with reference to FIGS. FIG. 9 is a flowchart for explaining the processing procedure of the seat aggregating apparatus according to the first embodiment. FIG. 10 is a flowchart for explaining the processing procedure of the operation number calculation process of the seat aggregation device according to the first embodiment.

FIG. 14 is a flowchart for explaining the processing procedure of the aggregation notification processing of the seat aggregation device according to the first embodiment. FIG. 15 is a flowchart for explaining the processing procedure of the electric equipment control processing of the seat aggregation device according to the first embodiment.

  As shown in FIG. 9, when the seat aggregating apparatus 10 receives an instruction to start the seat aggregating process from the user (Yes in step S101), the operating number calculating process (described later) that calculates the operating number of PCs installed in each area. (See FIG. 10) (step S102).

  Then, the seat aggregating apparatus 10 performs an aggregation area calculation process (see FIG. 12 described later) for determining whether or not to perform aggregation (step S103), and when it is determined that aggregation is not performed (Yes in step S104). Returning to step S102, the process is repeated.

  In addition, when it is determined that the aggregation is to be performed (No at Step S104), the seat aggregation device 10 performs an aggregation notification process (see FIG. 14 described later) for notifying an instruction to perform the aggregation (Step S105). An electrical device control process (see FIG. 15 to be described later) for controlling the power on / off of the device is performed, and the process is terminated.

  Next, the processing procedure of the number-of-operating-unit calculation process for the seat aggregation device according to the first embodiment will be described with reference to FIG. As shown in FIG. 10, the seat aggregating apparatus 10 determines whether one hour has elapsed since the process of calculating the previous operating number (step S201). Then, when one hour has elapsed from the process of calculating the previous operating number (Yes in step S201), the seat aggregating apparatus 10 calculates a PC operating number calculation process (described later) that calculates the operating number of PCs installed in the area. (See FIG. 11) (step S202).

  Then, the seat aggregating apparatus 10 determines whether or not the number of operating units for the previous time is greater than the current number of operating units (step S203), and if the number of operating units for the previous time is less than the current number of operating units (No at step 203). Return to step S201. Further, when the number of operating units in the previous time is larger than the current operating number (Yes at Step S203), the seat aggregation device 10 determines whether 5 minutes have elapsed since the previous operating number calculation process (Step S204). Then, the seat aggregating apparatus 10 repeats the process of step S204 when five minutes have not elapsed since the previous operation number calculation process (No at step S204).

  In addition, when five minutes have elapsed since the previous operation number calculation process (Yes in step S204), the seat aggregation device 10 calculates a PC operation number calculation process (FIG. 11 described later) that calculates the number of operation of PCs installed in the area. (See step S205). Then, the seat aggregating apparatus 10 determines whether or not one hour of PC operation data has been collected (step S206). If one hour of PC operation data has not been collected (step S206 negative), the process proceeds to step S204. Return. Further, when collecting the PC operation data for one hour (Yes at Step S206), the seat aggregating apparatus 10 determines whether the number of operating hours in the previous hour is larger than the average operating number in units of 5 minutes (Step S207). . As a result, when the number of operating units in the previous hour is less than the average operating number in units of 5 minutes (No at Step S207), the seat aggregation device 10 returns to Step S201.

  In addition, when the number of operating units in the previous hour is greater than the average operating number of units in 5 minutes (Yes in step S207), the seat aggregating apparatus 10 determines an aggregation area determination process for determining whether or not to perform aggregation (FIG. 12) (step S208), and the process ends.

  Next, a processing procedure for calculating the number of operating PCs of the seat aggregation device 10 according to the first embodiment will be described with reference to FIG. As shown in FIG. 11, the seat aggregating apparatus 10 acquires the power usage amount of one PC from the power supply monitoring device 20 (step S <b> 301), and holds the power usage amount of the PC in the operating number storage unit 11. (Step S302).

  Then, the seat aggregating apparatus 10 determines whether the power usage of the PC is larger than the standby power (for example, 20 watts) (step S303), and determines that the power usage of the PC is not larger than the standby power. (No at step S303), the process returns to step S301. If the seat aggregating apparatus 10 determines that the amount of power used by the PC is greater than the standby power (Yes at Step S303), the seat aggregation device 10 adds 1 to the number of operating units (Step S304), and determines the operating status of the PCs in the area. It is determined whether all have been confirmed (step S305). As a result, if all the operation statuses of the PCs in the area have not been confirmed (No at Step S305), the seat aggregating apparatus 10 returns to Step S301, acquires the power usage amount of another PC, and Repeat the process.

  In addition, when all the operation statuses of the PCs in the area are confirmed (Yes in Step S305), the seat aggregation device 10 holds the PC operation number in the area in the operation number storage unit 11 (Step S306). Then, the seat aggregating apparatus 10 determines whether the PC operating status has been confirmed for all areas (step S307), and when the PC operating status has not been confirmed for all areas (No at step S307), Returning to step S301, the power usage of the PC in another area is acquired, and the above processing is repeated. In addition, when the seat aggregation device 10 confirms the operating status of the PC for all the areas (Yes in step S307), the seat aggregation device 10 ends the process.

  Next, the processing procedure of the aggregation area calculation process of the seat aggregation device according to the first embodiment will be described with reference to FIG. As shown in FIG. 12, the seat aggregating apparatus 10 acquires the current number of operating PCs (N) from the operating number storage unit 11 (step S401), and calculates the number of PCs installed in an area from the floor information storage unit 12. Obtain (step S402). Here, from which area the number of PCs is acquired in order can be arbitrarily set, but for example, the number of PCs may be acquired in order from the area with the largest number of operating units.

  Then, the seat aggregating apparatus 10 determines whether the number of area PCs, which is the number of PCs installed in the area, is larger than the current PC operating number (N) (step S403). As a result, if it is determined that the number of area PCs is not larger than the current number of operating PCs (N) (No at step S403), the area as the number used in the area after aggregation in the aggregation result storage unit 13 The number of PCs is recorded (step S404). Then, the seat aggregating apparatus 10 sets N as a value obtained by subtracting the number of area PCs from N (step S405), returns to step S402, and repeats the above processing.

  Further, when the seat aggregation device 10 determines that the number of area PCs is larger than the current PC operation number (N) (Yes in step S403), N is recorded as the area usage number in the aggregation result storage unit 13. (Step S406). The seat aggregating apparatus 10 determines whether the number of areas where the number of PCs used is 1 or more is less after aggregation than before aggregation (step S407), that is, an area where all the devices in the area are not operating. Determine if the number could be increased. As a result, if the number of areas where the number of PCs used is 1 or more is less after aggregation than before aggregation (Yes at step S407), the seat aggregating apparatus 10 determines whether or not to aggregate. Processing (see FIG. 13 described later) is performed (step S408), and the processing is terminated. In addition, when the number of areas where the number of PC use is 1 or more is not less after aggregation than before aggregation (No at step S407), the seat aggregation device 10 determines that aggregation is not performed (step S409). The process ends.

  Next, the processing procedure of the aggregation determination process of the seat aggregation device according to the first embodiment will be described with reference to FIG. As illustrated in FIG. 13, the seat aggregation device 10 acquires a non-aggregation area from the aggregation result storage unit 13 (step S501). Here, the non-aggregation area is an area in which the number of operating PCs before aggregation is 1 or more and the number of operating PCs after aggregation is 0.

  Then, the seat aggregating apparatus 10 acquires the operating PC information of the non-aggregating area from the operating number storage unit 11 (Step S502), and acquires the total C of shutdown power of the operating PCs of the non-aggregating area from the floor information storage unit 12. (Step S503).

  Subsequently, the seat aggregating apparatus 10 acquires the total D of electric appliance power in the non-aggregated area from the floor information storage unit 12 (step S504). The seat aggregating apparatus 10 acquires an aggregation area from the aggregation result storage unit 13 (step S505), and acquires non-operating PC information of the operating area from the operating number storage unit 11 (step S506).

  Then, the seat aggregating apparatus 10 acquires the sum E of starting powers of the non-operating PCs in the aggregation area from the floor information storage unit 12 (step S507). That is, the number of operating units N in the expected aggregation area minus the number of operating units B in the aggregation area before aggregation is the number of PCs that are newly activated in the aggregation area, and the PCs that are newly activated in the aggregation area The total E of starting power is obtained.

  Subsequently, the seat aggregating apparatus 10 determines whether or not the reduced power D reduced by aggregation is greater than the aggregate cost power C + E, which is the power required for aggregation (step S508), and the reduced power D reduced by the aggregation. Is larger than the aggregate cost power C + E, which is the power required for aggregation (Yes at Step S508), it is determined that the aggregation is performed (Step S509), and the reduced power D reduced by the aggregation is aggregated If it is not greater than the aggregate cost power C + E, which is the required power (No at Step S508), it is determined that no aggregation is performed (Step S510), and the process ends.

  Next, a processing procedure of the aggregation notification process of the seat aggregation device 10 according to the first embodiment will be described with reference to FIG. As shown in FIG. 14, the seat aggregating apparatus 10 acquires a non-aggregated area and an aggregated area from the aggregation result storage unit 13 (step S601), and acquires operating PC information of the non-aggregated area from the operating number storage unit 11 ( Step S602). Then, the seat aggregating apparatus 10 displays a message prompting the aggregation notifying unit 18 to move to the aggregation area on the operating PCs in the non-aggregation area (step S603).

  Next, the processing procedure of the electrical equipment control process of the seat aggregation device according to the first embodiment will be described with reference to FIG. As illustrated in FIG. 15, the seat aggregating apparatus 10 acquires a non-aggregated area from the aggregation result storage unit 13 (step S701), and acquires information on the electrical devices installed in the non-aggregated area from the floor information storage unit 12. (Step S702).

  Then, the seat aggregating apparatus 10 controls the power supply of the operating electrical equipment in the non-aggregated area from the power supply control unit 19, and stops the electrical equipment (step S703). For example, the seat aggregating apparatus 10 turns off the PC, air conditioning equipment, and lighting in the non-aggregated area.

  Subsequently, the seat aggregating apparatus 10 obtains the power used by electric devices other than the PCs in the aggregation area (step S704), and when the power used is 0 (or only standby power), the power control unit 19 performs non-operating electricity. The power supply of the device is controlled, the electric device is started (step S705), and the process ends.

[Effect of Example 1]
As described above, the seat aggregating apparatus 10 collects the power usage of each device installed in each area, and uses the collected power usage of each device to determine whether each device is operating. And calculate the number of operating devices in all areas. Then, the seat aggregating apparatus 10 collects all the devices in the area when the devices to be operated are aggregated into a specific area based on the calculated number of operating devices and the number of installed devices in each area. Determine whether it is possible to increase the number of areas that are not operating, and if it is determined that all the devices in the area can be increased, identify the devices that are operating Outputs an instruction to consolidate the areas. For this reason, as a result of moving the user to a specific area and consolidating PCs operating in the specific area, it is possible to turn off the air conditioning facilities and lighting in areas where the equipment is not operating. It is possible to reduce power consumption.

  Further, according to the first embodiment, the seat aggregation device 10 collects the power usage of each device installed in each area at the first time interval, and uses the collected power usage of each device. It is determined whether or not each device is operating, and the number of operating devices in all areas is calculated every hour. Then, the seat aggregating apparatus 10 compares the calculated current number of operating devices with the previous number of operating devices, and determines whether the current number of operating devices is smaller than the previous number of operating devices. judge. When the seat aggregation device 10 determines that the current number of operating devices is smaller than the previous number of operating devices, the seat integrating device 10 calculates the number of operating devices and the number of devices installed in each area. Based on the above, it is determined whether or not the number of areas in which all the devices in the area are not operating can be increased when the operating devices are aggregated in a specific area. As a result, the seat aggregating apparatus 10 can aggregate devices operating at appropriate timing into a specific area in accordance with the transition of the power consumption. For example, it is possible to consolidate operating devices in a specific area after classes are over or when there are fewer people such as overtime hours.

  Further, according to the first embodiment, when it is determined that the current number of operating devices is smaller than the previous number of operating devices, the seat aggregating apparatus 10 has an interval of 5 minutes shorter than an hour interval, Collect the power usage of each device installed in each area, use the collected power usage of each device to determine whether each device is operating, and the number of devices operating in all areas Is calculated every 5 minutes. Then, the seat aggregating apparatus 10 calculates the average value of the number of operating devices at intervals of 5 minutes within one hour interval, compares the calculated average value with the previous number of operating devices, and the average value is It is determined whether it is less than the number of operating devices. In this way, the seat aggregating apparatus 10 obtains the average value of the number of operating devices every 5 minutes shorter than an hour interval and determines the transition of the power consumption, so that, for example, the number of people temporarily decreases. However, when the number of people increases afterwards, it is possible to consolidate efficiently operating devices in a specific area as a result of preventing users from performing unnecessary movement for aggregation. .

  In addition, according to the first embodiment, the seat aggregation device 10 stores the number of devices operating for each area before aggregation and the number of devices scheduled to operate for each area after aggregation. In addition, the seat aggregating apparatus 10 sequentially subtracts the number of installed devices in the area with higher priority from the calculated number of operating devices in the area, and aggregates the number of installed devices in the area in the area. The number of devices scheduled to be operated later is sequentially stored in the aggregation result storage unit 13, and all devices in the area are operated from the number of devices scheduled to operate for each area after aggregation stored in the aggregation result storage unit 13. It is determined whether or not the number of areas that have not been increased can be increased. As a result, if it is determined that the number of areas where all the devices in the area are not operating can be increased, the seat aggregating apparatus 10 operates for each area after aggregation stored in the aggregation result storage unit 13. According to the planned number of devices, an instruction to collect the devices to be operated into a specific area is output. For this reason, as a result of consolidating PCs that operate in the order of higher priority areas, it is possible to turn off air conditioning facilities and lighting in areas where equipment is not operating, and reduce power consumption Is possible. Here, for example, by increasing the priority in an area where there are many devices that operate, minimizing unnecessary movements for aggregation to the user, and as a result, efficiently operating devices are made specific areas. It is possible to aggregate.

  Further, according to the first embodiment, when it is determined that the number of areas in which all devices in the area are not operating can be increased, the seat aggregation device 10 aggregates the devices in the area into a specific area. It is determined whether or not the power that can be reduced is greater than the power required to aggregate the devices in the area into a specific area. When the seat aggregating apparatus 10 determines that the power that can be reduced by consolidating the devices in the area into the specific area is greater than the power required to consolidate the devices in the area into the specific area, Outputs an instruction to consolidate operating devices into a specific area. For this reason, if the power consumption cannot be reduced even if the aggregation is performed, the aggregation process can be stopped.

  Further, according to the first embodiment, if the seat aggregation device 10 determines that the number of areas where all the devices in the area are not operating can be increased, the seat aggregation device 10 is an area where all the devices are not operated due to the aggregation. Turn off the device and turn on the devices in the aggregation destination area. For this reason, the seat aggregating apparatus 10 can automatically perform an aggregation process for aggregating devices in a specific area.

  By the way, when determining whether or not to perform the aggregation, it may be determined whether or not the aggregation is performed using the past PC usage number history.

  Therefore, in the following second embodiment, as a case where it is determined whether or not the aggregation is performed using the past PC usage number history, the seat aggregation device 10A according to the second embodiment will be described with reference to FIGS. The configuration and processing will be described.

  First, the configuration of the seat aggregation device 10A according to the second embodiment will be described with reference to FIG. FIG. 16 is a block diagram illustrating the configuration of the seat aggregation device according to the second embodiment. As illustrated in FIG. 16, the seat aggregation device 10 </ b> A according to the second embodiment is different from the seat aggregation device 10 according to the first embodiment illustrated in FIG. 2 in that a use history storage unit 13 a is newly included.

  The usage history storage unit 13a stores a history of the number of PCs that have started operating every predetermined time period. Here, an example of a table stored in the usage history storage unit will be described with reference to FIG. FIG. 17 is a diagram illustrating an example of a table stored in the usage history storage unit. For example, as illustrated in FIG. 17, the usage history storage unit 13 a stores visitors in a time zone of 12:00:00 to 22:00 in a period of 4/1 to 4/10, and for each time zone. The average value of the visitors is stored as “predicted number of visitors”. Here, the visitors are those who have entered the area and who have used a PC. That is, the difference between the number of operating PCs in the time period and the number of operating PCs in the time period before the time period, which is the number of PCs started to be used in the time period, is the number of visitors.

  The operating number calculation unit 15 determines whether each PC is operating using the power usage of each PC collected by the used power collecting unit 14, and calculates the operating number of PCs in all areas. At the same time, the prediction of the number of visitors after the current time is obtained from the usage history storage unit 13a, and the number of PCs in all areas where the number of PCs is calculated assuming that the number of PCs scheduled to start operation is assumed. Calculate the expected number of units added to the number of units in operation.

  Based on the predicted number of operating units calculated by the operating unit calculation unit 15 and the number of installed PCs in each area, the aggregation determination unit 17 aggregates operating PCs in a specific area. It is determined whether or not the number of areas where all the PCs are not operating can be increased. Specifically, the aggregation determination unit 17 compares the number of operating PCs in the previous hour and the expected number of operating units, and if the expected number of operating units is smaller than the number of operating PCs in the previous period, It is determined whether the number of areas where the PC is not operating can be increased. When the number of areas where all the PCs in the area are not operating can be increased, it is determined that the aggregation process is performed.

  Here, the aggregation process performed by the seat aggregation apparatus 10A will be described using the example of FIG. FIG. 18 is a diagram for explaining an example of the aggregation process. As illustrated in FIG. 18, the seat aggregating apparatus 10 </ b> A determines that the number of operating PCs “5” at 19:00 is smaller than the number of operating PCs “1” at 18:00. For this reason, the seat aggregating apparatus 10 calculates the number of PCs operating in all areas at intervals of 5 minutes between 19: 00 and 19: 55, and every 5 minutes between 19: 00 and 19: 55. The average value of the number of operating PCs is calculated. Then, the seat aggregating apparatus 10 compares the average number of operating PCs every 5 minutes between 19:00 and 19:55 with the operating number of PCs at 18:00. In the example of FIG. 18, the average value “5.0” of the number of operating PCs at intervals of 5 minutes between 19:00 and 19:55.

  Here, the seat aggregating apparatus 10A according to the second embodiment acquires the predicted attendees after 20:00 from the usage history storage unit 13a, and operates the PC every 5 minutes between 19:00:00 and 19:55. The expected number of operating units “6.3” is calculated by adding the expected number of visitors “1.3” after 20:00 to the average number of units “5.0”.

  The seat aggregating apparatus 10A according to the second embodiment compares the number of operating PCs “11” at 18:00 with the expected operating number “6.3”, and the predicted operating number “6.3” is 18:00. Therefore, it is determined that the aggregation process is performed.

  In this case, the seat aggregating apparatus 10A determines whether or not the number of areas in which all PCs in the area are not operating can be increased when operating PCs are aggregated in a specific area. In the example of FIG. 18, five units are operating at 19:55, and the operating PCs can be aggregated into a specific area to make the PCs not operating areas. A process for aggregating PCs that are in operation. Here, the number of operating units in area 1 is 0, the number of operating units in area 2 is 1, the number of operating units in area 3 is 2, the number of operating units in area 4 is 2, and priority is given to areas with many operating units. In order to reduce the movement of users by aggregating operating PCs, the users in area 2 are moved to area 3 to perform aggregation processing.

  In this way, by utilizing the history of the past number of PCs used, it is possible to predict the number of operating machines in the future, and more appropriately determine whether or not to perform the aggregation process. For example, even if the current operating number decreases from the previous operating number, the operating number increases after that (for example, when the operating number temporarily decreases during lunch or lectures) However, even if the PC users are moved to a specific area by performing aggregation processing and the power supply of the air conditioning equipment and lighting can be temporarily cut off, the number of operating units will increase, and the air conditioning equipment and lighting will increase. Therefore, the movement of PC users is wasted due to aggregation. In order not to perform such a useless movement, the seat aggregation device 10A predicts an increase in the number of operating units from the past history of the number of PCs used, and efficiently performs aggregation processing.

  Next, the processing procedure of the aggregation area calculation process of the seat aggregation device 10A according to the second embodiment will be described with reference to FIG. FIG. 19 is a flowchart for explaining a processing procedure of an aggregation area calculation process of the seat aggregation device according to the second embodiment. As shown in FIG. 19, the aggregation area calculation process of the seat aggregation device according to the second embodiment is compared to the aggregate area calculation process of the seat aggregation device according to the first embodiment shown in FIG. The difference is that the number of visitors is added to calculate the expected operating number.

  That is, as shown in FIG. 19, the seat aggregating apparatus 10A acquires the current PC operation number (X) from the operation number storage unit 11 (step S801), and uses the expected number of visitors (Y) after that as the usage history. Obtained from the storage unit 13a (step S802), the current number of operating PCs (X) and the expected number of visitors (Y) are added to calculate the expected number of operating units (N) (step S803).

  Thereafter, the seat aggregation apparatus 10A acquires the number of PCs installed in a certain area from the floor information storage unit 12 (step S804), and installs in the area more than the current PC operating number (N), as in the first embodiment. It is determined whether the number of area PCs, which is the number of PCs that have been sent, is greater (step S805). As a result, when it is determined that the number of area PCs is not larger than the current PC operating number (N) (No in step S805), the area as the number used in the area after aggregation is stored in the aggregation result storage unit 13. The number of PCs is recorded (step S806). Then, the seat aggregating apparatus 10A sets N as a value obtained by subtracting the number of area PCs from N (step S807), returns to step S804, and repeats the above processing.

  If the seat aggregation device 10A determines that the number of area PCs is larger than the current PC operating number (N) (Yes at step S805), N is recorded as the number of area use in the aggregation result storage unit 13. (Step S808). Then, the seat aggregation apparatus 10A determines whether the number of areas with one or more PCs used is less after aggregation than before aggregation (step S809), that is, an area in which all devices in the area are not operating. Determine if the number could be increased. As a result, if the number of areas where the number of PCs used is 1 or more is smaller after aggregation than before aggregation (Yes in step S809), the seat aggregation device 10A determines whether or not to aggregate. Processing is performed (step S810), and the processing is terminated. In addition, when the number of areas where the number of PCs used is 1 or more is less after aggregation than before aggregation (No in step S809), the seat aggregation device 10A determines that aggregation is not performed (step S811). The process ends.

  As described above, according to the second embodiment, the seat aggregation device 10A further includes the history information storage unit 13a that stores the history of the number of devices that have started operation every predetermined time period. Then, the seat aggregating apparatus 10A uses the collected power usage amount of each device to determine whether each device is operating, calculates the number of operating devices in all areas, and after the current time A history of the number of devices that have started operation is acquired from the history information storage unit, and an expected operating number is calculated by adding the operating number of devices in all areas where the number of devices has been calculated. Then, when the seat aggregation device 10A aggregates the operating devices into a specific area based on the calculated expected number of operations and the number of devices installed in each area, all the devices in the area It is determined whether the number of areas that are not operating can be increased. As described above, the seat aggregation device 10A can predict the number of operating units in the future by utilizing the past history, and can more appropriately determine whether or not to perform the aggregation process.
