"Developed the industry's smallest smart power strip with built-in power sensor", [online], March 31, 2010, Fujitsu Laboratories Ltd., [searched on January 15, 2011], Internet <http: // pr .fujitsu.com / jp / news / 2010/03 / 31-3.html>

  The smart power strip incorporates a sensor that detects a current flowing through a plug connection portion exemplified by an outlet. Therefore, for example, it is possible to measure the power consumption for each plug connection unit. As a result, the user can know the power consumed by the devices connected to each plug connection unit with specific numerical values. If the power consumption is excessive, the user tries to save power without waste.

  However, even if the power consumption can be accurately detected, power saving is not always performed based on the detection result. For example, if the user determines that the detected power consumption includes waste, the user saves power to reduce this waste. However, if the user determines that the detected power consumption is not wasteful, the user saves power. Not performed. If the user subjectively determines whether there is any waste in this way, there is a tendency that power is not saved sufficiently. This tendency is due to the fact that the standards of how far and where the consumption is wasted vary from user to user, especially those who are more likely to waste power, and this criterion is not appropriate. Because.

  It is an object of the disclosed technology to provide a technology for measuring the power consumption of a plurality of users, giving them a ranking, and supporting the reduction of the power consumption.

One aspect of the disclosed technology is exemplified by the following configuration of the information processing apparatus. That is, the information processing apparatus identifies a communication unit that acquires a detection value associated with each of a plurality of plug connection units provided in a power connection device, and a user of each plug connection unit of the power connection device.

The area is also called an installation area in the sense that the repeater 2 is installed. The area ID can also be referred to as the ID of the repeater 2. Therefore, the IP address, MAC address, etc. of the repeater 2 may be used as the area ID. Moreover, you may provide ID which this power consumption evaluation system manages uniquely as area ID. When the ID uniquely managed by the power consumption evaluation system is used as the area ID, an address association table for associating the area ID with the IP address or the MAC address of the repeater 2 may be provided.

  When the repeater 2 is newly installed, the energy management server 3 receives an operation on the input device 38, starts a computer program, and functions as the power connection device setting unit 301. However, the energy management server 3 may start a computer program in accordance with an operation from the monitoring terminal 5 and function as the power connection device setting unit 301, for example.

  The power connection device setting unit 301 displays a power connection device setting screen on the screen of the display device 37 or the like by a user operation, and is connected to the ID of the area corresponding to the installed repeater 2 and the repeater 2. The setting of the ID of the power connection device 1 and the ID of the current sensor included in the power connection device 1 is supported. For example, the power supply device setting unit 301 searches for a free ID, displays it to the user, and prompts the user to set it as an ID of a newly installed area or the like, an ID of the repeater 2, and an ID of a current sensor. The power supply device setting unit 301 stores the ID of the area set by the user, the ID of the repeater 2, and the ID of the current sensor in the power supply device database 311. The power connection device database 311 includes a sensor ID table and an installation area ID table. The sensor ID table defines IDs of individual current sensors in the power connection device 1. Further, the installation area ID table defines the relationship between each area of the office and the power supply connection device 1 in the area.

Then, the connected device determination unit 303 hands over the relationship between the authorized user, the power connection device 1, the power value of each outlet, and the standby power value to the power saving totaling unit 306. The regular user is a person who is normally assigned to each outlet of the power connection device 1 and is permitted to use it. Hereinafter, regular users are also referred to as users.

  Based on the relationship between the user acquired from the connected device determination unit 303 and the outlet C1, the power totaling unit 304 totalizes the power value of each outlet read from the power value database 312 for each user.

  The ranking unit 309 ranks the total value of the power totaling unit 304. The ranking unit 309 is an example of an evaluation unit. In addition, the output unit 310 outputs the result of ranking by the ranking unit 309. Here, the output may be display output by the display device 37, sound output by sound or the like, print output, data output to another computer, that is, data transmission.

  For example, in response to a request from the user's PC, the output unit 310 reads information in the personal ranking database 314 and delivers it to the user's PC. The output unit 310 corresponds to an example of a means for displaying a comprehensive evaluation score. Delivering means, for example, creating a ranking screen based on information in the personal ranking database 314, and transmitting and displaying the ranking screen on the user's display device. As such a data exchange procedure, HTTP (HyperText Transfer Protocol) or the like is known. A display output example of the output unit 310 will be described later with reference to FIG. However, the output unit 310 may search for information in the personal ranking database 314 requested from the PC, pass the searched information to the PC, and cause the application program on the PC to execute the creation of the ranking screen.

  In addition, the power totaling unit 304 of the present embodiment includes a total power totaling unit 305, a use average totaling unit 307, an average previous week ratio totaling unit 308, and a power saving totaling unit 306.

  The total power totalization unit 305 obtains a total power value for a predetermined period by integrating the power values detected at each outlet. The use average totalization unit 307 calculates average power for a predetermined period. The average used weekly ratio totaling unit 308 obtains the ratio between the average used power of this week and the average used power of the previous week.

The power saving totaling unit 306 is based on schedule information in the schedule database 318 or a work schedule on a day (also referred to as a designated date) that is a target of processing by the power saving totaling unit 306. Determine the seat status. The power saving totaling unit 306 is an example of an evaluation unit. Then, the power saving totaling unit 306 verifies the power consumption value of a device connected to the outlet such as a PC (Personal Computer) based on the presence / absence status of the user of the outlet, and the user performs the energy saving action. It is determined whether or not it is taken. Such processing of the power saving totaling unit 306 is referred to as energy saving action determination processing. If the result of the determination is that it is not possible to confirm that the energy saving action is taken, the power saving totaling unit 306 registers the used power value in the personal ranking database 314 as wasted power.

  On the other hand, when it can be confirmed that the energy saving action is taken, the power saving totaling unit 306 registers the maximum power consumption of the device connected to the outlet in the personal ranking database 314 as the energy saving power. Here, the energy saving power is a power value that is considered to have been reduced by the user taking energy saving action.

The power saving totaling unit 306 provides the following functions, for example.
(1) Prior to the energy saving action determination process, the power saving totaling unit 306 calculates the first standby power and the second standby power for each device connected to the outlet. The first standby power is power that is supplied to the device through the outlet when the device is powered off. The first standby power is also referred to as energized power.

  The second standby power is power that is supplied to the device through the outlet when the device is on and is operating in the standby mode or the power saving mode.

(2) For the outlet user, when it is determined that the power consumption is not reduced despite the absence schedule information registered in the schedule database 318, the power saving totaling unit 306 Waste power due to not being reduced is calculated and registered in the personal ranking database 314. Whether or not the power consumption is reduced may be determined based on, for example, whether or not the power consumption of the device is equal to or lower than the second standby power.

  On the other hand, when the power consumption is reduced during the time zone when the schedule information for leaving the seat is registered in the schedule database 318, the power saving totaling unit 306 uses the energy saving power due to the reduction in the power consumption. Calculate and register in the personal ranking database 314.

  As described above, in the first embodiment, the energy management server 3 refers to the schedule database 318 for acquiring the user's schedule information. The schedule database 318 is managed by, for example, groupware, workflow, and the like, and stores schedule information of users such as office staff and employees. In the schedule information, a schedule related to the user's leaving, for example, a schedule such as attending a conference, a business trip, and going out is set.

<Database configuration>
Hereinafter, the configuration of a database in which the energy management server 3 inputs and outputs data will be exemplified. FIG. 7 is a configuration example of a sensor ID table included in the power connection device database 311, and FIG. 8 is a configuration example of an installation area ID table. As illustrated in FIG. 6, the power connection device database 311 includes a sensor ID table and an installation area ID table.

  Among these, the sensor ID table associates the power connection device ID and the sensor ID. The power connection device ID is identification information that uniquely identifies the power connection device 1. The sensor ID is identification information of a current sensor included in the power connection device 1.

The installation area ID table associates an area ID, an area name, and a power supply device ID. The area ID is identification information of an area where the repeater 2 is installed. As already described, one repeater 2 is installed in the area. Therefore, the area ID can be said to be identification information for uniquely identifying the repeater 2. The area ID is the IP of the repeater 2
It may be an address or a MAC address.

  The area name is the name of the area. The area name indicates to the user or the administrator of the power consumption evaluation system which area the area identified by the area ID is actually recognized by the person. In the example of FIG. 8, the names of floors such as 1F and 2F are illustrated as area names. However, the area is not always defined corresponding to the floor. For example, a plurality of areas may exist on one floor. A plurality of floors may be combined into one area.

  The power connection device ID is identification information of the power connection device 1 installed in each area. In the example of FIG. 8, for example, the power connection device ID is set to “01 to 03” in the area “1F”. However, in the installation area ID table, for example, individual area IDs may be listed as area IDs. In addition, a field for individually storing each area ID may be provided in the installation area ID table in the form of an array.

  In this embodiment, as one of the area IDs, the ID of the monitoring terminal 5 (for example, “Z”), the installation area of the monitoring terminal 5 (for example, “B1F”), and the ID of the monitoring terminal 5 (for example, , 00) is defined. The area of the monitoring terminal 5 is defined so that the manager of the power consumption evaluation system or the manager of the office using the power consumption evaluation system can recognize the position of the monitoring terminal 5. Because. This is because if the position of the monitoring terminal 5 can be recognized, it is convenient for the management of the relay 2, the power connection device 1, the device to which power is supplied from the power connection device 1, and the like.

  FIG. 9 illustrates the configuration of the power value database 312. The power value database 312 includes fields of power connection device IDs, sensor IDs, and power values for each sensor time zone. The power connection device ID and the sensor ID have already been described in the power connection device database 311. In FIG. 9, the power value is stored in a time zone, for example, at a time interval of 10 minutes. In the case of an interval of 10 minutes, the use average power value for 10 minutes may be stored. However, in addition to the average value, the maximum value, the minimum value, and the like may be stored. Further, for example, the power value at each start point of the time zone, the power value at the time in the middle of the time zone, the power value at the end point of the time zone, and the like may be stored. For example, detection by the current sensor is performed at intervals of 1 second, and any one of an average value, a maximum value, a minimum value, a detection value at the time zone start point, a detection value at the center time, a detection value at the time zone end point, etc. One or more may be stored.

  However, an appropriate time interval for storing the power value may be selected depending on the management accuracy required for the power consumption evaluation system, the scale of the system, the capacity of the external storage device in which the database is constructed, and the like. For example, the power value may be stored at intervals of 5 minutes. Further, for example, the power value may be stored at intervals of 1 second.

  As a method of storing the power value, in FIG. 9, a time zone is specified in the table column. Therefore, after storing the power value detection start time, the detection end time, and the time width (time interval for saving) as management information, the power value column may be saved in the database. Or you may preserve | save the row | line | column which combined (time of detection of a power value, power value), for example.

FIG. 10 illustrates the configuration of the connected device database 313. The connected device database 313 associates a power supply connected device ID, a sensor ID, a connected device, a first standby power value, a second standby power value, and a user ID. In FIG. 10, the connected device being “PC” indicates that the PC is connected to the outlet specified by the power connection device ID and the sensor ID defined in the row. On the other hand, the connection device being “arbitrary” indicates that there is no restriction on the device connected to the outlet specified by the connection device ID and the sensor ID defined in the row.

  In the field of the first standby power value, a first standby power value of a device connected to the corresponding outlet of the power connection device 1 defined in the power connection device database 311 is defined. The first standby power value is also referred to as energized power. The first standby power value is a power value supplied to the device from the outlet when the power of the device connected to the outlet is off. For example, some PCs consume predetermined power in preparation for power on even when the power is off. For example, a PC that is activated when a packet is received via a LAN is known. Such a PC function is called a wake-on LAN.

  In the second standby power value field, a second standby power value of a device connected to the corresponding outlet of the power connection device 1 defined in the power connection device database 311 is defined. The second standby power value is, for example, power supplied from the outlet to the PC when the PC is in a standby state.

  The user ID is information for identifying an authorized user of the power connection device 1 defined in the power connection device database 311. Here, the regular user is a user who is properly assigned the power connection device 1. The user ID is information for uniquely identifying the user. For example, the user ID or the user identification information registered in the energy management server 3, the login name of the PC, or the user identification on the groupware is used. Information, e-mail address, etc. However, a user ID may be set for each outlet. The connected device database 313 is an example of a user storage unit.

  The connection device determination unit 303 illustrated in FIG. 6 corresponds to the relationship between the power supplied to the device connected to the outlet and the first standby power value and the second standby power value of the device, and the power supply connection device 1. The user ID is notified to the power saving counting unit 306. The power saving totaling unit 306 wastes power based on the relationship between the power supplied from the outlet to the device, the first standby power value, the second standby power value, and the device user schedule set in the schedule database 318. The presence or absence of is determined. When power consumption is confirmed, the power saving totaling unit 306 registers, in the energy saving database 316, alert information indicating that the user specified by the user ID is not taking energy saving action.

  FIG. 11 illustrates the configuration of the user database. The user database associates the relationship between the user ID and the group ID. The user ID has been described in the connected device database 313. The group ID is information for identifying a group. The group is, for example, a workplace department, a department, a department or the like. The relationship between the user specified by the user ID and the group is defined by the user database. By referring to the user database, power management for each group is realized. For example, regarding energy saving behavior, it is possible to create a group-to-group comparison, an in-house ranking between groups, and the like. In the first embodiment, the term “department” will be used as a typical example of a group.

  In addition to the user ID and group ID, the user database may further hold a node name, an IP address, a MAC address, and a mail address in association with each other. Here, the node name is identification information on the network of the PC used by the user with the user ID. The node name may be, for example, identification information on a LAN provided by a PC OS (Operating System) vendor. The IP address may be a local IP address on the LAN in the office or a global IP address on the Internet. The MAC address is an address of the data link layer possessed by the network board of the PC used by the user with the user ID. The e-mail address is an e-mail address assigned to the user with the user ID.

  The user database may store all of the node name, IP address, MAC address, and mail address, or may store only a part thereof, for example, only the node name. That is, in this power consumption evaluation system, the energy management server 3, the PC, the monitoring terminal 5, and the like may communicate using at least one of a node name, an IP address, a MAC address, and a mail address. The user database stores the relationship between the user ID and the group ID, and the relationship between the user ID and the node name, IP address, MAC address, mail address, etc. is held in another table. Also good.

  FIG. 12 illustrates the configuration of the schedule database 318. The schedule information registered in the schedule database 318 is an example of the expected work information of the user. Note that information indicating holidays, scheduled departure dates, etc. in the holiday calendar master database 319 is also an example of expected work information of users. In the schedule database 318, schedule information is registered and managed by the schedule management server 6, and is shared among users. One row (record) in the table shown in FIG. 12 defines one schedule. Each row of the schedule database 318 has fields for a user ID, start date / time, end date / time, title, and status flag.

  The user ID is identification information of a user whose schedule is managed in the schedule database 318. The user ID of the schedule database 318 and the user ID of the connected device database 313 may be a common ID. When the user ID of the schedule database 318 and the user ID of the connected device database 313 are common, the power consumption evaluation system determines that the authorized user of the outlet of the power connected device 1 and the user of the schedule database 318 Can be associated as they are. In addition, when the user ID of the schedule database 318 and the user ID of the connected device database 313 are different, a database that associates the user ID of the schedule database 318 and the user ID of the connected device database 313 with each other is provided. Just do it.

  The start date / time and end date / time are the start date / time and end date / time of a schedule to be registered as a schedule, for example, a conference schedule or a business trip schedule. The title is information indicating the contents of the schedule. The title is, for example, “committee”, “meeting (outside)”, or the like.

  Information indicating the user's intention for the schedule is set in the status flag. When the status flag is 1: approval, the user's intention to act according to the schedule is indicated. Therefore, when the status flag is 1: approval, the power consumption evaluation system predicts that the user will act as scheduled.

  On the other hand, a status flag of 2: refusal indicates a user's intention that the user does not act according to the schedule. Therefore, when the status flag is 2: refusal, the power consumption evaluation system expects the user to act ignoring the schedule. A status flag of 3: Delete indicates that the schedule has been deleted. When the status flag is 3: deletion, it is handled as if there was no schedule.

  FIG. 13 illustrates the configuration of the personal ranking database. The personal ranking information is one of the tabulation results of the ranking unit 309. One row (record) in the table of FIG. 13 corresponds to the ranking result of one user's ranking.

  As shown in FIG. 13, each row of the personal ranking information includes fields for user ID, year, week number, used average power, total power, used average previous week, energy saving power, and wasted power.

  The user ID is the same as that of the connected device database 314. In the year field, information indicating the year in which rankings are tabulated is set. In the week number field, information specifying the week in which rankings are tabulated is set. That is, in the example of FIG. 13, it is assumed that the ranking is totaled once a week. However, ranking aggregation is not limited to once a week. For example, the ranking may be aggregated every day. When the rankings are aggregated every day, a date such as 1-31 may be set as the day number instead of the week number. In addition, the ranking may be totaled for one month every month. When the ranking is totaled every month, information indicating the month such as 1-12 may be set as the month number instead of the week number. The ranking for one year may be totaled. Furthermore, the ranking is not limited to the year, month, and day units, and the ranking may be aggregated in an irregular period. When rankings are aggregated in irregular periods, information (start date, end date, etc.) for specifying the start and end of the aggregation period may be set instead of the week number.

  The used average power field has sub-fields of quantity and ranking. The used average power value is stored in the quantity subfield. The used average power value is an average value of used power by the user in a total period, for example, one week specified by a week number in the example of FIG. The used average power value is a power value obtained by dividing the amount of power (Wh) obtained by integrating the used power in the counting period by the value obtained by dividing the seated time (= time equal to or longer than the first standby power).

  The total power field also has sub-fields for quantity and ranking, like the field for average power used. The total power value is stored in the quantity subfield. The total power value is an amount of power obtained by integrating the power used by the user in a total period, for example, one week specified by a week number in the example of FIG.

  The field of average used weekly ratio has subfields for quantity and ranking. The quantity subfield stores a value (%) obtained by dividing the average power used this week by the average power used last week.

  FIG. 14 illustrates the configuration of the department ranking database 315. The department ranking database 315 is one of the counting results of the ranking unit 309. One row (record) in the table of FIG. 14 corresponds to the ranking result of one department.

  As shown in FIG. 14, each row of the department ranking information includes fields of department ID, year, week number, average used power, total power, average used weekly ratio, energy saving power, and wasted power. Among these, the department ID is information for identifying a department to which the user belongs, that is, a subordinate organization in the organization, for example, in a company, a government office, a school, a public organization, or the like. Other fields are the same as those in the personal ranking database 314 in FIG.

<Example of processing by the system>
FIG. 15 illustrates processing by the power consumption evaluation system according to the time axis. The following is a processing example according to the function provided by the power saving totaling unit 306 of the energy management server 3.

The vertical axis in FIG. 15 illustrates the power consumption for each type of device connected to the outlet C1. Furthermore, the schedule of the schedule database 318 is illustrated as an item at the bottom of FIG. Here, the schedule is a schedule of the user of the power connection device 1 including the outlet on the vertical axis in FIG. The user of the power supply connection device 1 is specified by the user ID in the connection device database 313. FIG. 15 shows the case of user A. Further, the schedule information of the schedule database 318 is specified by the user ID.

  Further, a PC is connected to the outlet C1 of the sensor ID01a, a fan is connected to the outlet C1 of the sensor ID01b, and a stand illumination is connected to the outlet C1 of the sensor ID01c, while a device is connected to the outlet C1 of the sensor ID01d. Explain that there is no.

  And this power consumption evaluation system determines the electric power usage condition of the outlet by which power is detected by sensor ID: 01a, 01b, 01c during the time zone of an internal meeting. That is, this power consumption evaluation system determines whether or not the power supply to the PC connected to the outlet C1 with the sensor ID 01a is at a sufficiently small level during the in-house conference time zone. Further, in the power consumption evaluation system, whether or not the power supplied to the fan connected to the outlet C1 with sensor ID: 01b and the stand lighting connected to the outlet C1 with sensor ID: 01c is at a sufficiently small level. Determine whether. The sufficiently small level is, for example, a level equal to or lower than the second standby power defined in the connected device database 313, and is 30 W or less for the PC connected to the outlet C1 with the sensor ID: 01a. In addition, regarding a fan connected to the outlet C1 with the sensor ID 01b or a stand illumination connected to the outlet C1 with the sensor ID 01c, a sufficiently small level is a level at which the power consumption is zero.

  Then, according to each determination result, the power saving totaling unit 306 of this power consumption evaluation system registers the value of waste power or the value of energy saving power in the personal ranking database 314. Here, the value of the waste power is a value obtained by subtracting the second standby power value from the detected power value. On the other hand, the value of energy saving power is a value obtained by subtracting the second standby power value from the maximum power value defined in the connected device database 311.

For example, in the determination indicated by NG1-NG3 in FIG. 15, since the supplied power is not at a sufficiently small level in the time zone of the in-house meeting, the power value consumed during this time is used as the value of wasted power in the personal ranking database 314. Registered in the field of wasted power. For example, a value obtained by multiplying the power consumption value of the PC detected by the current sensor CS1 with the sensor ID: 01a by the time when the schedule is entered, that is, the away time, is set as the waste power value. Further, the present invention is not limited to this, and a value obtained by subtracting the second standby power value from the detection value may be used. For example, if the detected value is 65 W, the value of wasted power may be a value obtained by multiplying the second standby power value of 30 W by 35 W and the away time.

  On the other hand, in the meeting time outside the company from 13:00 to 15:00, in the determinations indicated by G11 and G12, since the power supplied to the PC and the fan is sufficiently low, power saving is achieved during this period. The power value considered to have been registered is registered in the field of energy saving power of the personal ranking database 314 as the energy saving power value. For example, the maximum power value of the PC is obtained from the connected device database 313 and is set to a value obtained by multiplying the maximum power value by the time during which the schedule is entered. Further, the present invention is not limited to this, and a value obtained by subtracting the second standby power value from the maximum power value may be used. For example, if the maximum power value is 66 W, 36 W obtained by subtracting 30 W of the second standby power value may be multiplied by the away time to obtain the energy saving power value.

  Similarly, also for the lunch break time zone, the power supplied to the PC connected to the sensor ID: 01a, the electric fan connected to the sensor ID: 01b, and the stand illumination connected to the sensor ID: 01c is at a sufficiently small level. It is determined whether or not. For example, in the determination of G51 and G52 in FIG. 15, since the power supplied to the PC and the fan is sufficiently small during the lunch break, the energy saving power value is registered in the personal ranking database 314. .

<Processing flow>
FIG. 16 illustrates a flowchart of power management preparation processing by the energy management server 3. The energy management server 3 executes power management preparation processing by a computer program that is executably deployed in the main storage device. The power management preparation process is a process executed as a premise of the power consumption evaluation process shown in FIG.

  First, the energy management server 3 sets IDs of the power connection device 1 and the sensor (S1). For example, when a new power connection device 1 is installed in the office, the system administrator accesses the energy management server 3 to launch a predetermined definition screen, and uses the newly installed power connection device 1 as an energy source. Register in the management server 3. For example, for the power connection device 1 having a four-port outlet, the system administrator sets one power connection device ID and four sensor IDs. At the time of setting, the energy management server 3 may display an unused power connection device ID and an unused sensor ID on the screen to prompt the system administrator to select with a pointing device or the like. The energy management server 3 stores the power connection device ID and the sensor ID in association with each other in the sensor ID table of the power connection device database 311 according to the designation of the system administrator.

  Further, the energy management server 3 sets standby power for each sensor (S2). Details of S2 will be described later with reference to FIGS.

  Moreover, the energy management server 3 sets ID of an installation area (S3). As already described, in the first embodiment, the installation area is an area covered by the repeater 2. In the process of S2, for each installation area, the relationship between the area ID and one or more power connection devices 1 arranged in each area is defined. When a new repeater 2 is installed in the office, the system administrator accesses the energy management server 3 and launches a predetermined definition screen. Then, the system administrator registers, in the energy management server 3, the area ID of the area covered by the newly installed repeater 2, the area name, and the relationship between the power connection devices 1 arranged in the area.

  At the time of setting, the energy management server 3 may display an unused area ID on the screen and prompt the system administrator to select with a pointing device or the like. In addition, the energy management server 3 displays a list of power connection devices that have been registered in the power connection device database 311 but are not arranged in the area, and prompts the system administrator to select by a pointing device or the like. May be. Further, the energy management server 3 may accept an input of an area name from the system administrator. The energy management server 3 associates the area ID, the area name, and the power connection device ID arranged in the area with the installation area ID table of the power connection device database 311 in accordance with the designation of the system administrator as described above. And save.

  In addition, you may make it the energy management server 3 collect use electric power (detection current of a current sensor) from the power supply connection device 1 without using the repeater 2. In the power consumption evaluation system that does not use the repeater 2, the area ID and the power connection device ID may be stored in a one-to-one correspondence. Moreover, what is necessary is just to perform the process of the above S1 to S3 separately from the power consumption evaluation process of the energy management server 3, and to perform offline. Moreover, the process of S1 and the process of S2 do not need to be performed sequentially.

The energy management server 3 collects current values from the current sensors of the respective power supply connection devices 1 via the repeaters 2 (S4). For example, the current value may be periodically acquired from each current sensor of the power supply connection device 1 in the area covered by the repeater 2 and reported to the energy management server 3. The report may include, for example, the current value detected by the current sensor at the time of the report together with the power supply device ID and the sensor ID. However, the repeater 2 may arrange the current values acquired from the respective power connection devices 1 and the respective current sensors in a predetermined order, and report them to the energy management server 3 in the form of current value vector data. The energy management server 3 may read the current value of each current sensor according to the format of the current value vector data. The energy management server 3 may convert the collected current value into a power value and store it in the power value database 312 in the format shown in FIG.

  In this case, the energy management server 3 may store all the collected power values in the power value database 312. Further, the energy management server 3 may store a part of the collected power values as a sample in the power value database 312.

  More specifically, the repeater 2 acquires a current value at a relatively short period, for example, at an interval of 1 second, and transmits it to the energy management server 3. Then, the energy management server 3 may convert all the current values transmitted from the repeater 2 into power values and store them in the power value database 312. The energy management server 3 obtains sample values from the set of current values transmitted from the repeater 2 at predetermined intervals, for example, at intervals of 5 minutes, converts them into power values, and stores them in the power value database 312. Also good. The energy management server 3 obtains an average value, a maximum value, a minimum value, a value at the beginning of the period, a power value at the end of the period, and the like from the current value transmitted from the repeater 2, and a power value database 312 may be stored.

  FIG. 17 is a flowchart illustrating the details of the process of setting the standby power value for each sensor (S2 in FIG. 16). In this process, the energy management server 3 executes the processes of S21 and S22 for all the sensors whose power values are reported through the repeater 2.

  In FIG. 17, the energy management server 3 first calculates the first standby power and the second standby power based on the power value detected by each current sensor (S21). Then, the energy management server 3 sets the first standby power and the second standby power in association with the sensor ID of the connected device database 313 (S22).

  FIG. 18 is a flowchart illustrating a process of calculating the first standby power and the second standby power (details of S21 in FIG. 17). In this process, the energy management server 3 first creates a histogram of power values for a predetermined period, for example, the previous day, of each sensor in the power value database 312 (S211). The histogram may be obtained by classifying the detected power for each sensor in the power value database 312 from 0 W to a predetermined wattage width and obtaining a frequency distribution. The width of the predetermined wattage may be, for example, a width that divides the range of the maximum wattage from 0 watts into 10 divisions or 100 divisions. Alternatively, it may simply be a fixed wattage width such as 0.1 watt, 1 watt, 10 watt, etc.

  Next, the energy management server 3 searches the histogram in the direction of increasing power from the position of 0 watts to obtain the first peak. The peak is a position where the frequency becomes maximum. And the energy management server 3 calculates | requires the electric power value which becomes the frequency 0 or the minimum value on the right side (electric power increase side) of the 1st peak, and makes it 1st standby electric power (S212). The CPU of the energy management server 3 executes the process of S212 by using a computer program developed on the main memory as an example of the first calculation unit.

FIG. 19 shows an example of a histogram. The first standby power can be considered to be power supplied from the outlet to the device in a state where the device connected to the outlet is not turned on. Further, as the first standby power, the power value that becomes the frequency 0 or the minimum value on the right side (power increase side) of the first peak is obtained near the maximum value that can be taken as the first standby power. Because. Therefore, the spreading portion on both sides from the first peak (for example, the portion from 0 watts to the first frequency 0 position on the power increasing side of the first peak or the position of the minimum value) is the first standby power. As a range of values that may be measured. The extended portions on both sides from the first peak are an example of the first distribution set. And the range of the 1st standby electric power can be covered by calculating | requiring the electric power value which becomes frequency 0 or the minimum value on the right side (electric power increase side) of the 1st peak, and making it 1st standby electric power. Moreover, the energy management server 3 can calculate the estimated value of the first standby power by the process of S212.

  Next, the energy management server 3 searches the histogram in the direction of increasing power from the first peak position, and obtains the second peak. And the energy management server 3 calculates | requires the electric power value which becomes frequency 0 or the minimum value on the right side (electric power increase side) of the 2nd peak, and makes it 2nd standby electric power (S213). The CPU of the energy management server 3 executes the process of S213 by a computer program developed on the main memory as an example of the second calculation unit.

  The second standby power can be considered as power supplied from the outlet to the device in the standby mode or the power saving mode after the device is turned on. Examples of the device in the standby mode or the power saving mode include a PC, a hard disk drive, and a display device. The standby mode and the power saving mode are collectively referred to as a power saving mode. Further, when measuring the power of the PC, the power of the entire device including the hard disk drive device, the display device, etc. may be measured, or the body portion of the desktop PC, that is, the housing portion including the CPU board, etc. The power may be measured.

  Further, as the second standby power, the power value that becomes the frequency 0 or the minimum value on the right side (power increase side) of the second peak is obtained near the maximum value that can be taken as the second standby power. Because. In other words, the second standby power can be considered as a power that is larger than the first standby power and smaller than the power supplied to a device such as a normally operable PC. Therefore, in order to exclude the portion of the frequency distribution included in the first peak, the power value that becomes the frequency 0 or the minimum value on the right side (power increase side) of the second peak is set as the second standby power. The extended part on both sides from the second peak is an example of the second distribution set. By classifying the power below the first standby power as the first standby power, at least the power value classified as the first standby power can be excluded from the power values classified as the second standby power. And the range of the 2nd standby electric power can be covered by calculating | requiring the electric power value which becomes frequency 0 or the minimum value on the right side (electric power increase side) of the 2nd peak, and setting it as the 2nd standby electric power. Further, the energy management server 3 can calculate the estimated value of the second standby power by the process of S213.

  In FIG. 17-19, the energy management server 3 exemplifies the process of calculating the first standby power and the second standby power. However, the administrator of the power management system uses the catalog value or the like to determine the first standby power. The second standby power may be input.

  FIG. 20 illustrates a flowchart of power consumption evaluation processing by the energy management server 3. The energy management server 3 executes a power consumption evaluation process by a computer program that is developed to be executable on the main storage device. This process is activated in an offline batch process at a time set by the administrator of the power consumption evaluation system, for example, once a day, once a week, or the like. However, the administrator of the power consumption evaluation system may manually start the process of FIG. When the administrator manually activates the process of FIG. 20, a period to be subjected to the energy saving action determination process may be designated. The energy management server 3 executes the process of FIG. 20 by the trigger according to the above conditions.

First, the energy management server 3 confirms the connected devices connected to the respective power supply connected devices 1 from the connected device database 313 (S6). Then, the energy management server 3 acquires the relationship between the power value collected in the process of S4 in FIG. 16 and the connected device connected to the power supply connected device 1 from which the power value is collected.

  Next, the energy management server 3 acquires a power value for a predetermined evaluation period, for example, one week, from the power value database 312 (S7). And the energy management server 3 totals the acquired electric power value based on a predetermined | prescribed reference | standard, calculates | requires the total value for every user, and registers it in a personal ranking database (S8). Here, the aggregation based on a predetermined standard is to obtain an aggregate value such as total power, average usage power, average usage average weekly ratio, energy saving power, and waste power, as will be described in detail later. The CPU of the energy management server 3 executes the counting process of S8 by a program developed in the main storage device as an example of a counting unit.

  Further, the energy management server 3 acquires values of total power, used average power, used average weekly ratio, energy saving power, and wasted power from the personal ranking database 314 as evaluation items (S9). Next, the energy management server 3 compares and ranks each user value for each evaluation item, and registers this ranking in the personal ranking database 314. Further, the values of these evaluation items are compared and ranked for each department to which each user belongs, and are registered in the department ranking database 315 (S10). As an example of the evaluation unit, the CPU of the energy management server 3 executes the ranking process of S10 using a program developed in the main storage device.

  FIG. 21 is a flowchart illustrating the details of the power totaling process (S8 in FIG. 20).

  In this process, the energy management server 3 executes the following processes S81 to S85 in a loop for the number of persons. To loop for the number of people means to execute the following processing for each user identified by the user ID.

  First, the energy management server 3 sets initial values for variables (S81). For example, variables “wk energy saving power” and “wk waste power” for storing values of energy saving power and waste power are set, and the values are set to 0, respectively. Moreover, the energy management server 3 selects one user ID.

  Next, the energy management server 3 acquires all the power values detected at the outlet corresponding to the user ID selected in step S81, that is, the total power value, from the power value data of the predetermined evaluation period acquired in step S7. (S82).

  Further, the energy management server 3 inquires of the schedule management server 6 about the presence time of the user identified by the user ID selected in step S81, and receives and stores the presence time from the schedule management server 6 (S83). ).

  Next, the energy management server 3 inquires the schedule management server 6 about the seating time of the user identified by the user ID selected in step S81, and collates the schedule with the power consumption as will be described later to reduce the wasteful power and energy saving. Ask for power. Note that the processing in steps S82 to S84 is repeatedly executed for all outlets C1 assigned to the user.

  Then, the energy management server 3 registers the total power obtained in step S82, the average power used based on the total power, the average previous week ratio, the energy saving power and the waste power obtained in step S84 in the personal ranking database.

FIG. 22 illustrates details of the schedule check flow (S84 in FIG. 21). In this process, the energy management server 3 acquires the schedule information of the schedule database 318 and confirms whether or not the device used by the user is using electric power according to the user's schedule. In this process, the energy management server 3 first acquires schedule information for a specified date from the schedule database 318 (S811). The CPU of the energy management system 3 executes the process of S811 by means of a computer program on the main memory as an example of means for acquiring the expected work information of the user.

  Here, the schedule information to be acquired is, for example, one row (one record) of the schedule database 318 illustrated in FIG. Further, as shown in FIG. 21, the schedule check process loops for different number of outlets. Therefore, the schedule information acquired in the process of S811 is the schedule information of the authorized user of the outlet currently being processed. For example, the user ID may be specified by referring to the connected device database 313 from the outlet ID of the outlet currently being processed. Then, the schedule database 318 is referred to from the specified user ID, and the schedule information related to the specified user ID may be acquired. In the processing of S811, the schedule information on the designated date is a specific point in the past, for example, a schedule with a start date and time of yesterday, a schedule for last week, and the like. However, the schedule check flow may be executed in real time. In the case of real-time processing, the schedule information on the specified date is a schedule whose start date and time is today's schedule, or whose current time is between the start date and time and the end date and time. The current time is provided by, for example, a calendar function and a time function of the OS of the energy management server 3. Therefore, the schedule of the designated date of the user of a certain outlet can be acquired by the processing of S811. The same applies to the other processes described below regarding the designated date.

  Then, the energy management server 3 determines whether there is an approval schedule in the acquired schedule (S812). The approval schedule refers to schedule information indicating a user's intention to follow the schedule. According to the schedule, for example, in the case of a meeting schedule, attend the meeting, in the case of a business trip schedule, or on a business trip. In the approval schedule, the status flag is set to 1 as illustrated in FIG. When the approval information is not included in the schedule information acquired in the process of S811, the energy management server 3 ends the schedule check flow. In the first embodiment, the approval schedule is used. However, the schedule information may be provided with a field for information indicating absence, for example, a business trip, a meeting, paid vacation, and the like. In step S812, it may be determined whether or not the user has displayed his / her schedule for leaving the seat and indicates his / her intention to follow the schedule.

  On the other hand, when the approval schedule is included in the schedule information acquired in the process of S811, the energy management server 3 supplies the power supplied to the device connected to the outlet at the schedule intermediate time specified by the schedule. Is acquired (S813). Here, the schedule intermediate time is an intermediate time in the time zone from the start date to the end date shown in the schedule information (see FIG. 12). There is no particular limitation on the intermediate time, and for example, the time in the middle of the time zone may be used. The power acquired in the process of S813 is referred to as schedule intermediate power.

  Next, the energy management server 3 determines whether the schedule intermediate power has been acquired (S814). The case where the schedule intermediate power cannot be acquired is, for example, the case where the power at the schedule intermediate time is not recorded. When the schedule intermediate power cannot be acquired, the energy management server 3 advances the process to S817.

On the other hand, when the schedule intermediate power can be acquired, the energy management server 3 determines whether or not the schedule intermediate power is larger than the second standby power (S815). Here, the second standby power is, for example, power supplied to a device when a device such as a PC is in a standby state. When the schedule intermediate power is smaller than the second standby power, the energy management server 3 determines that there is no waste of power at the outlet currently being processed. Therefore, the energy management server 3 obtains the maximum power of the device connected to the outlet currently being processed from the connected device database 313, obtains the energy saving power by multiplying the schedule period (time), and adds it to the variable “wk energy saving power”. . (S818).

  On the other hand, when the schedule intermediate power is larger than the second standby power in step S815, the energy management server 3 determines that power is wasted at the outlet currently being processed. Therefore, the energy management server 3 obtains waste power by multiplying the power value detected during the schedule at the outlet currently being processed by the schedule period (time) (S816).

  Then, the energy management server 3 determines whether or not the next unprocessed schedule information remains in the schedule database 318 (S817). If unprocessed schedule information remains, the energy management server 3 returns the process to S812. On the other hand, when there is no unprocessed schedule information remaining, the energy management server 3 ends the schedule check flow.

  As described above, the energy management server 3 is specified by the approval ID and the sensor ID of the power connection device 1 assigned to the user in the time zone in which the user's absence is registered as schedule information. Based on the power consumption of the device at the outlet, the user's presence or absence of energy saving behavior is determined. When the energy saving action cannot be confirmed, the energy management server 3 calculates the waste power and registers it in the personal ranking database 314. The case where the energy saving behavior cannot be confirmed can be the case where the waste is confirmed. On the other hand, when the energy saving action is confirmed, the energy management server 3 calculates the energy saving power and registers it in the personal ranking database 314. Through the above processing, the energy management server 3 allows the user to calculate waste power and energy saving power according to the schedule in the schedule database 318.

  FIG. 23 illustrates the details of the power value totaling process (S85 in FIG. 21). First, the energy management server 3 registers the total power acquired in step S82 of FIG. 21 in the personal ranking database 314 (S810). Further, the energy management server 3 registers the value accumulated by the variable “wk energy saving power” in the personal ranking database 314 as the energy saving power value (S820).

  Next, the energy management server 3 registers the value accumulated by the variable “wk waste power” in the personal ranking database 314 as a waste power value (S830).

  Moreover, the energy management server 3 calculates | requires use average electric power by dividing | segmenting total electric power by the value which remove | divided seated time by the number of outlets like following Formula (S840). The average power used is not limited to this, and may be a value obtained by dividing total power by attendance time.

Average power used = total power / (attended time / number of outlets)
Then, the energy management server 3 registers this used average power in the personal ranking database 314 (S850).

  Further, the energy management server 3 divides this weekly average usage power by the previous week's average usage power and multiplies it by 100 to obtain the average weekly ratio (S860). Then, the energy management server 3 registers this average weekly ratio in the personal ranking database 314 (S870).

  FIG. 24 illustrates the details of the ranking process, that is, the process of ranking the values of the respective evaluation items and performing relative evaluation (S10 in FIG. 20).

  The energy management server 3 first ranks the total power value and registers it in the personal ranking database 314 (S91), then ranks the average power used and registers it in the personal ranking database 314 (S92), The ranking is compared with the average week in use and registered in the personal ranking database 314 (S93). Further, the energy management server 3 ranks the energy saving power and registers it in the personal ranking database 314 (S94), and then ranks the waste power and registers it in the personal ranking database 314 (S95).

  The energy management server 3 refers to the user database 31B, counts the number of users associated with each department, and acquires the number of persons belonging to each department (S96). Next, the energy management server 3 divides the total power for each department by the number of members, ranks it and registers it in the department ranking database 315 (S97), and divides the total used average power for each department by the number of members. Ranking and registering in the department ranking database 315 (S98). Further, the energy management server 3 divides the total of the average use week-to-week for each department by the number of affiliations, ranks it, and registers it in the department ranking database 315 (S99). Are divided by the number of affiliations, ranked and registered in the department ranking database 315 (S100).
