  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing an overall configuration showing an embodiment of a personal use power monitoring system according to the present invention and a block configuration showing an embodiment of a personal use power monitoring apparatus according to the present invention. FIG. 1 shows a configuration in which an entrance / exit management server 1, a card reader controller 2, a building management server 3, a monitor controller 4, and a personal use power monitoring device 20 are connected via a network 5.

  Further, FIG. 1 shows a room 6 for monitoring the power used in individual units in this system. Since the configuration in each room 6 may be the same, only one room 6 is shown in FIG. The entrance / exit 7 of the room 6 is provided with a card reader 8a over which an IC card is placed when a person enters the room and a card reader 8b over which an IC card is placed when the person leaves the room. The card reader 8a and the card reader 8b are collectively referred to as “card reader 8”. In the IC card, a user ID is recorded as identification information for specifying a user carrying the IC card. In the room 6, a plurality of seats 9 for employees belonging to a certain department are arranged. Of course, the present invention is also applicable to a private room in which only one seat is placed. The power usage meter 10 is installed corresponding to each seat. Each employee uses an electric device such as a seasonal home appliance such as a PC or a fan, a mobile phone, or a table lamp in his / her seat 9, but each electric power meter 10 is used in each seat 9. Connected. Thereby, the used power measuring device 10 measures the used power for each individual in real time.

  This embodiment operates in conjunction with an entrance / exit management system that manages employee entrance / exit and a building management system that monitors and manages the power used in the facility.

  The entrance / exit management system is connected to a card reader 8 installed at the entrance / exit 7 of each room 6, a card reader controller 2 provided corresponding to each room, and one or a plurality of card reader controllers 2 for entrance / exit management. An entry / exit management server 1 is included. When the IC card holder holds the IC card over the card reader 8, the card reader 8 reads at least the user ID from the IC card, and transmits information including the read user ID, the read date and time, and identification information of the device itself. . The card reader controller 2 collects information sent from the card reader 8 by reading the IC card and transmits it to the entrance / exit management server 1. When the entry / exit management server 1 acquires information transmitted from the card reader 8 via the card reader controller 2, the entry / exit management server 1 generates entry / exit information including the user ID, the entry / exit date / time of the user, and the entry / exit. And register it in a predetermined entry / exit information database. The entrance / exit management server 1 has a database in which the identification information of the card reader 8 is associated with information for specifying the installation location of the card reader 8 (the installed side 6 and the entrance / exit side of the entrance / exit 7). Therefore, it can be determined from the identification information of the card reader 8 included in the acquired information whether the user's action is entering or leaving the room. The entrance / exit management system manages entry / exit of employees by accumulating entrance / exit information in this way.

  In addition to the database described above, the entrance / exit management server 1 includes a department, a room used by the department, a superior of the department, and employees who belong to the department and have seats in the room. A group information database for storing group information in which each identification information is associated. Furthermore, it has a personal information database that stores personal information in which each user's e-mail address as a contact address of each user is associated with the user ID.

  On the other hand, the building management system is connected to a power consumption measuring instrument 10 installed corresponding to each seat 9, a monitor controller 4 provided corresponding to each room, and one or a plurality of monitor controllers 4 to connect power consumption. A building management server 3 for monitoring is included. The electric devices used in each seat are all connected to the power usage meter 10 and are supplied with power via the power usage meter 10. The power line is omitted from the figure. The power consumption measuring device 10 transmits information including power consumption measured at the time of transmission, measurement date and time, and identification information of the device itself at a transmission interval (for example, 1 minute) set in advance. The monitor controller 4 transmits information transmitted from the power usage meter 10 at regular intervals to the building management server 3. When the building management server 3 acquires information transmitted from the power consumption meter 10 via the monitor controller 4, the building management server 3 generates power usage information including the user ID, the measurement date and time, and the measured power usage. Register in the power information database. Since the building management server 3 has a database in which the identification information of the power usage meter 10 is associated with the user ID of the user who uses the seat 9 in which the power usage meter 10 is installed, the acquired information The user who used electric power is specified from the identification information of the used electric power measuring instrument 10 contained in. In the building management system, by accumulating power usage information in this way, the power usage of each employee is monitored as a function of building management.

  FIG. 2 is a hardware configuration diagram of a server computer forming the personal use power monitoring apparatus 20 in the present embodiment. In the present embodiment, the server computer forming the personal power monitoring apparatus 20 can be realized with a general-purpose hardware configuration that has existed in the past. That is, the computer is provided as a CPU 31, a ROM 32, a RAM 33, an HDD controller 35 to which a hard disk drive (HDD) 34 is connected, a mouse 36 and a keyboard 37 provided as input means, and a display device as shown in FIG. An input / output controller 39 to which each display 38 is connected and a network controller 40 provided as communication means are connected to an internal bus 41. Since the entrance / exit management server 1 and the building management server 3 are the same computer, the hardware configuration can be illustrated in the same manner as in FIG.

  Returning to FIG. 1, the configuration of the personal power monitoring apparatus 20 will be described. The personal power consumption monitoring device 20 includes an entrance / exit information acquisition unit 21, a power usage information acquisition unit 22, a performance recording unit 23, a management information acquisition unit 24, an analysis unit 25, a notification unit 26, a control unit 27, and a personal power consumption information storage. A portion 28 is provided. The entrance / exit information acquisition unit 21 acquires entrance / exit information from the entrance / exit management server 1. The used power information acquisition unit 22 acquires used power information from the building management server 3. The performance record unit 23 is provided as a generation unit, generates personal use power information including the use power and occupancy status of each user for every fixed time from the acquired entrance / exit information and use power information, and the personal use power information Register in the storage unit 28. The analysis unit 25 determines whether or not there is a power saving action when each user leaves the room by analyzing the personal use power information stored in the personal use power information storage unit 28. Here, the “power saving action” means an action for reducing power consumption such as putting the PC in a sleep mode when leaving the room or turning off the monitor of the PC or the table lamp. The notification unit 26 notifies the user who is determined by the analysis unit 25 that there is no power saving action. The management information acquisition unit 24 acquires information necessary for notification by the notification unit 26 such as an e-mail address from the entrance / exit management server 1. The control unit 27 performs overall control of processing in the personal use power monitoring apparatus 20 such as executing processing in cooperation with each of the components 21 to 26.

  FIG. 3 is a diagram showing an example of personal use power information stored in the personal use power information storage unit 28 in the present embodiment. The personal power usage information is a occupancy flag for each user as the occupancy information indicating the date / time when the power usage was measured, the power usage measured at the measurement date / time, and the presence / absence of the user at that date / time. Are generated in association with each other. In the present embodiment, the flag value “1” is set when the user is in the room, and the flag value “0” is set when the user is in the room (not present). The personal power usage information is generated for each user, but may be further generated by being divided at regular intervals such as days.

  The components 21 to 27 in the personal use power monitoring apparatus 20 are realized by a cooperative operation of a computer that forms the personal use power monitoring apparatus 20 and a program that operates on the CPU 31 mounted on the computer. The personal power consumption information storage unit 28 may be realized by the HDD 34 mounted on the personal power consumption monitoring device 20. Alternatively, it may be provided on another computer accessible via the network 5.

  Further, the program used in this embodiment can be provided not only by communication means but also by storing it in a computer-readable recording medium such as a CD-ROM or DVD-ROM. The program provided from the communication means or the recording medium is installed in the computer, and various processes are realized by the CPU 31 of the computer sequentially executing the program.

  Next, the operation in this embodiment will be described. In the present embodiment, the personal use power information generation process for generating personal use power information and the personal use power monitoring process for performing a notification for invoking a power saving action based on the generated personal use power information can be roughly divided. . First, a process for generating personal use power information necessary for performing the personal use power monitoring process will be described.

  As described above, in the entrance / exit management system, each time an employee enters / exits the room 6, entrance / exit information including the user ID, the entry / exit date / time of the user, and the entry / exit information is generated. Accumulated in the server 1. On the other hand, in the building management system, the electric power used in each seat 9 is measured every predetermined fixed period (in this embodiment, every minute), the user ID of the user who uses the measured seat 9, and the measurement Power usage information including date and time is generated and stored in the building management server 3. The used power information acquisition unit 22 acquires the used power information that has not been acquired from the building management server 3 every minute in accordance with the transmission interval in the used power meter 10. In other words, the power usage information stored immediately before is acquired from the building management server 3. The entrance / exit information acquisition unit 21 acquires entrance / exit information from the entrance / exit management server 1 in accordance with the information acquisition cycle in the power usage information acquisition unit 22. When each of the information acquisition units 21 and 22 acquires the immediately preceding information, the result recording unit 23 generates personal usage power information including the usage power and occupancy information at the measurement date and time from the acquired entrance / exit information and usage power information. And registered in the personal power consumption information storage unit 28. The date and time and power consumption included in the personal power usage information are the measurement date and time and power usage included in the power usage information, and the occupancy information (in-room flag) included in the personal power usage information is included in the entry / exit information. Set a flag value based on whether you enter or leave the room. Specifically, when entry / exit information indicating that the user has entered the room is acquired for a user who is not in the room, “1” indicating the presence in the user is set in the presence flag of the user. When the entry / exit information indicating that the user has left the room is acquired, “0” indicating absence is set in the in-room flag of the user. Further, the previous flag value is inherited as it is for the in-room flag of the user whose entry / exit information has not been acquired. As described above, the personal use power information illustrated in FIG. 3 is generated for each user.

  Next, the personal use power monitoring process in the present embodiment will be described with reference to the flowchart shown in FIG. This personal use power monitoring process may be executed as a scheduled process, such as after the end of one working day, as will be understood from the contents of the process described below, or a predetermined one minute period or one hour period, etc. You may perform as a periodic process for every time interval. The personal power consumption monitoring process does not necessarily have to be executed for all users at once. In consideration of the processing load of the computer, all users such as departments are divided into a plurality of groups and executed at a predetermined timing. You may do it. Here, a description will be given assuming that processing is performed for all users after the end of one working day.

  The program for realizing the personal power consumption monitoring process includes processing functions in the management information acquisition unit 24, the analysis unit 25, and the notification unit 26, and is activated by the control unit 27 at a predetermined timing.

  When the program is activated, the analysis unit 25 acquires the personal use power information of the user who has not been analyzed yet from the personal use power information storage unit 28 (step 110). And the presence or absence of the power saving action of the said user is judged by analyzing the following personal use electric power information (step 120).

  For example, referring to the setting example of the personal use power information group 51 shown in FIG. 3, it can be imagined that the user comes to work at 9:00 and sequentially switches on the electrical devices in the seat 9. Here, the user determines that there is no particular need to perform power saving action while in the room.

  Referring to the setting example of the next personal use power information group 52 shown in FIG. 3, it is determined that the user is not particularly required to perform a power saving action because the user is in the room and has not left the room. Of course, even if you are in the room, if the power usage value is large, specifically for users who use electrical equipment that exceeds the preset power usage upper limit, a notification that calls for power-saving behavior May be performed.

  Referring to the setting example of the next personal use power information group 53 shown in FIG. 3, the user has left the room at 12:00, and the use power is greatly reduced at this timing. Therefore, it is determined that the user has performed a power saving action such as turning off the switch of the electric device.

  Referring to the setting example of the next personal use power information group 54 shown in FIG. 3, the user leaves the room at 15:00, but the use power does not decrease so much at this timing. Therefore, it is determined that the user is not performing a power saving action such as turning off the switch of the electric device.

  Referring to the setting example of the next personal use power information group 55 shown in FIG. 3, the user has left the room at 18:00, and the use power is greatly reduced to 0 at this timing. Therefore, it is determined that the user has performed a power saving action such as turning off the switch of the electric device. In this case, it can be imagined that the employee has left the office because the power used is zero.

  Here, the determination of the presence or absence of the power saving action will be described in detail. In the present embodiment, the presence or absence of power saving behavior is determined based on the degree of decrease in power consumption when leaving the room. Here, “at the time of leaving the room” is the date and time when the value of the in-room flag is changed from “1” to “0”. The degree of reduction can be the amount of reduction and the rate of reduction. The “decrease amount” means a decrease amount of power used at the time of leaving the room immediately before leaving the room as a result of comparing the measured power at the time of leaving the room and the measured power immediately before the room. In the setting example of the personal power consumption information group 54, since the power is reduced from 250W to 240W, the reduction amount in this case is 10W. The “decrease rate” refers to the rate of decrease in power used at the time of leaving the room immediately before leaving the room as a result of comparing the measured power at the time when the room is detected and the measured power immediately before. In the setting example of the personal power usage information group 54, since the power is reduced from 250 W to 240 W, the reduction rate in this case is (250−240) / 250 = 4%.

  Therefore, the amount or rate of decrease in power consumption before and after leaving the room is calculated, and the calculated value is compared with a preset threshold value. If the threshold value is not reached, it is determined that there is no power saving action of the user. For example, if 50 W is set as the reduction amount threshold, in the setting example of the personal power consumption information group 54, the reduction amount is 10 W and does not reach the threshold of 50 W, so it is determined that there is no power saving action. If the threshold value of the reduction rate is set to 5%, in the setting example of the personal power consumption information group 54, the reduction rate is 4% and does not reach 5%, so it is determined that there is no power saving action.

  This threshold value may be set based on a company's power saving target, or may be set based on the normal usage status of electrical equipment. In addition, the threshold value may be set in common for all users, or may be set for each group or each user based on the number and type of electric devices owned by each individual, or job title level, department, job, etc. . Information about each individual's department and the like is acquired from the entrance / exit management server 1 by the management information acquisition unit 24.

  By the way, depending on the person, since the work performed on a certain day is a work that does not use the PC, the power of the PC may be turned off before leaving the office. In this case, there is a possibility that the degree of decrease in power consumption does not reach a predetermined threshold when leaving the office when leaving the office. Then, there is a possibility that the user who has performed the power saving action before leaving the room is determined to have no power saving action. Therefore, in the present embodiment, even when there is no difference in power consumption obtained by measurement before and after leaving the room, the power used before leaving the room is below a preset power saving reference value. On the other hand, it is determined that there is power saving behavior of the user.

  For example, in the case where 60 W is set as the power saving reference value, the power consumption immediately before leaving the room is 40 W, and the power consumption at the time of leaving the room is 0 W. It is assumed that the threshold value (50 W) has not been reached. Even in such a case, when the power consumption (40 W) immediately before leaving the room is lower than the power saving reference value (60 W), it is determined that there is power saving behavior of the user. In this case, it can be considered that the power saving action was performed before leaving the room, not at the time of leaving the room.

  As described above, when it is determined that there is no power saving action in the analysis target user (N in step 130), the analysis unit 25 notifies the user that there is no power saving action. The unit 26 is instructed.

  Upon receiving the notification instruction, the notification unit 26 instructs the management information acquisition unit 24 to transmit a mail address transmission request including the user ID of the user to the entrance / exit management server 1. The management information acquisition unit 24 transmits a mail address transmission request to the entrance / exit management server 1 in response to this instruction. The entrance / exit management server 1 takes out the mail address of the user from the personal information database and returns it in response to the mail address transmission request.

  When the management information acquisition unit 24 acquires the email address sent from the entrance / exit management server 1, the notification unit 26 indicates that there is no power saving action by transmitting an email with the acquired email address as a destination. Notification is made (step 140). The e-mail may include other information such as the date and time when it is determined that there is no power saving action, power consumption, and so on.

  Here, the notification is given only to the user who has not taken the power saving action, but the administrator (superior) of the user has no power saving action in place of the user or with the user. May be notified. In this case, the management information acquisition unit 24 is instructed to transmit to the room entry / exit management server 1 a mail address transmission request including that the user's superior mail address is transmitted together with the user ID of the user. The management information acquisition unit 24 transmits a mail address transmission request to the entrance / exit management server 1 in response to this instruction. The entrance / exit management server 1 identifies the superior of the user by referring to the group information database in response to the mail address transmission request, and identifies the identified superior user ID. Then, the user having no power saving action and the e-mail address of the user are retrieved from the personal information database and returned. Thereafter, as described above, the notification unit 26 notifies that there is no power saving action by transmitting an e-mail addressed to the e-mail address acquired by the management information acquisition unit 24.

  Here, the e-mail address is taken as an example of the notification means, but notification may be made using other means.

  On the other hand, if it is not determined that there is no power saving action (Y in step 130), the analysis process is shifted to the next user (step 110). The above process is repeated for all users (step 150).

  In the present embodiment, the presence / absence of a power saving action is determined for each individual as described above, and a notice to that effect is given to a user who does not have a power saving action. Thereby, arousal of power saving action can be aimed at.

  In the above description, the power consumption is monitored in units of individuals. However, when power consumption can only be measured in units of rooms, not in units of individuals, a power saving action is promoted in units of rooms (units of departments). You may do it. The notification destination in this case may be an upper manager. Also in the present embodiment in which the power consumption can be measured for each individual, the individual power consumption may be grouped for each group such as a department so as to promote a power saving action for each group.

  Further, as is clear from the above description, the personal use power information generation process only needs to be completed before the personal use power monitoring process is performed.
