Description

  The present invention relates to a standby power reduction support system, a management server, and a standby power reduction support method that support reduction of standby power.

  In recent years, interest in energy conservation has increased due to concerns about global warming. In particular, standby power is consumed even when no load equipment is used, and in the case of homes, it accounts for about 10% of the annual usage, and the reduction is urgently needed. For example, Non-Patent Document 1 describes a report on standby power consumption in FY2005.

  For this reason, power consumption for 24 hours is measured on the main power distribution board of the consumer who is the user who consumes power, and the power consumption (standby power) at the time of quiet time when there are few operating devices such as midnight from the measured data. The apparatus which consumers themselves estimate is currently marketed (for example, refer nonpatent literature 2).

Moreover, a power measuring instrument that can be connected to an outlet of an individual load device as an adapter and can measure power consumption for 24 hours is also commercially available, and can obtain power consumption (standby power) of the load device when it is quiet (for example, Non-patent document 3).
Energy Conservation Center, “2005 Standby Power Survey Report”, http://www.eccj.or.jp/standby/05/00.pdf Energy Conservation Center, “Energy Conservation Navi”, http://www.eccj.or.jp/navi/index.html ENEGATE Co., Ltd., “NEW ECOWAT”, http://www.enegate.co.jp/ecowat_r.pdf

  However, in the conventional technique, there is a power consumption of a device that is always in operation even when it is quiet, so there is a problem that it is not possible to obtain an accurate standby power only by the total power consumption when it is quiet.

  In addition, it is possible to calculate the exact standby power by subtracting from the total power consumption during quiet periods by measuring the power consumption of the equipment that is always in operation using the power meter of the individual load device.

  FIG. 9 is a flowchart for explaining a power amount measuring method in the power amount measuring devices 102 and 105 shown in FIG. Here, the electric energy measuring instruments 102 and 105 have a built-in clock. Further, a case where the measurement start time is 1 am, the measurement end time is 6 o'clock, and the measurement time interval is preset to 30 minutes will be described as an example.

  First, it is determined whether or not the current time is 1:00 am, which is the measurement start time of the measurement time zone (step S1), and when it is determined that it is the measurement start time, measurement of the power consumption is started. (Step S2).

  Thereafter, it is determined whether or not a predetermined time (30 minutes) has elapsed (step S3). If it is determined that the predetermined time has elapsed, the measured electric energy is transferred from the electric energy measuring devices 102 and 105 to the controller. 103 (step S4).

  When the measured electric energy is transmitted from the electric energy measuring devices 102 and 105 to the controller 103, it is determined whether or not the current time is 6 am, which is the measurement end time of the measurement time zone (step S5). ).

  If it is determined that the current time is 6 am, which is the measurement end time, the measurement of the power consumption is completed (step S6).

  On the other hand, if it is determined in step S5 that the current time is not 6 am, which is the measurement end time, the process of step S3 is performed, and the current time is 6 am, which is the measurement end time. Until it is determined, the electric energy measured every predetermined time (30 minutes) is transmitted from the electric energy measuring instruments 102 and 105 to the controller 103.

  From the measurement start time to the measurement end time, the electric energy transmitted from the electric energy measuring devices 102 and 105 at a predetermined time interval is accumulated in the controller 103 at each measurement time. The electric energy accumulated in the controller 103 is used as electric energy information together with measurement time information indicating each measurement time, and is transmitted from the controller 103 via the router 109 and the communication line 107 at a predetermined time (a time later than the measurement end time). To the management server 106. At this time, the power amount information includes a user ID for identifying the consumer.

  Next, a method for creating standby power reduction support information in the management server 106 to which power amount information has been transmitted from the controller 103 will be described.

  FIG. 10 is a flowchart for explaining a method of creating standby power reduction support information in the management server 106 to which power amount information has been transmitted from the controller 103 shown in FIG.

When the communication unit 161 receives the power amount information transmitted from the controller 103 (step S11), the standby power calculation unit 162 calculates the standby power amount for each measurement time (step S12). This calculation method is as described above.
(Standby power consumption) = (Total power consumption)-(Power consumption of always-on electrical equipment)
It is. Here, (total power consumption) is the power amount measured by the power meter 102 and accumulated in the controller 103, and (power consumption of the constantly operating electrical device) is This is the amount of power measured by the power meter 105 and accumulated in the controller 103.

  The calculated standby power amount is stored in the history database 163 at each measurement time by the standby power calculation unit 162.

  Then, support information is created by the support information creation unit 166 (step S13). The specific procedure is shown below.

  First, the average value of the standby electric energy for each measurement time of the day is calculated. Based on the calculated average value, the power amount corresponding message information stored in the message database 167 is referred to, and the message number corresponding to the calculated average value (standby power amount) is acquired. Then, the message information stored in the message database 167 is referred to, and the message content corresponding to the acquired message number is acquired.

  Further, the standby power amount of the previous day is acquired from the history database 163, and the difference between the standby power amount of the current day and the standby power amount of the previous day is calculated. Based on the calculated difference, the power difference corresponding message information stored in the message database 167 is referred to, and the message number corresponding to the calculated difference (difference from the previous day) is acquired. Then, the message information stored in the message database 167 is referred to, and the message content corresponding to the acquired message number is acquired.

  Further, the past standby electric energy stored in the history database 163 is graphed.

  The above message and graph are associated with the user ID and stored in the support information database 168 as support information (step S14).

  When the support information is stored in the support information database 168, information indicating that the preparation of the support information is completed is transmitted (notified) from the communication unit 161 to the personal computer 108 via the communication line 107 and the router 109 (step S15). ). At this time, the notification destination is the corresponding user ID. However, when notification is performed using e-mail, an e-mail address corresponding to the user ID needs to be registered in the user information database 165 in advance.

  Next, a support information notification method in the management server 106 when the consumer who has received the notification from the management server 106 accesses the management server 106 from the personal computer 108 will be described.

  FIG. 11 is a flowchart for explaining a support information notification method in the management server 106 when a consumer accesses the management server 106 from the personal computer 108.

  The user ID and password input to the personal computer 108 by the customer to obtain support information are transmitted from the personal computer 108 to the management server 106 via the router 109 and the communication line 107, and are received by the communication unit 161. (Step 21), the authentication unit 164 performs user authentication (Step S22). This user authentication is authentication using a general user ID and password, and is performed by referring to the user ID and password stored in the user information database 165.

  When the authentication in step S22 is successful, the support information corresponding to the user ID is read from the support information database 168 by the support information creation unit 166 (step S23).

  The read support information is transmitted from the communication unit 161 to the personal computer 108 via the communication line 107 and the router 109 (step S24).

  The support information transmitted to the personal computer 108 is displayed on the personal computer 108.
