Preferably, the storage unit 60 includes a subscriber information storage 62, subscriber energy information storage 64, analysis energy information storage 66, acquaintance list storage 68. The subscriber information storage unit stores subscriber information for each subscriber (eg, personally identifiable information (name, social security number, ID, password, etc.), building type, building scale, life pattern analysis information, etc.). The subscriber energy information storage unit 64 stores, as subscriber energy information, power usage information for each subscriber uploaded through the gateway 20. Meanwhile, the subscriber energy information storage unit 64 also stores energy saving information provided by the subscriber. The analysis energy information storage unit 66 stores analysis energy information for each subscriber. The acquaintance list storage unit 68 stores an acquaintance list. The acquaintance list includes, for example, names, telephone numbers, etc. for friends, neighbors, and the like. In addition, the acquaintance list storage unit 68 stores 'friend registration' information for smooth sharing of the energy saving information tip.

The energy information analyzer 70 analyzes energy consumption behavior of each subscriber based on the subscriber energy information stored in the subscriber energy information storage 64. The energy information analysis unit 70 generates analysis energy information that is an analysis result and stores the analysis energy information in the analysis energy information storage unit 66. Here, the analysis energy information is preferably arranged by hour, week, month, period.

On the other hand, the energy information analysis unit 70 converts the analysis energy information into graphical information in the form of a graph according to the analysis data graph request from the power management terminal 30 and sends it to the output unit 90.

The energy information analysis unit 70 will be described in more detail. Based on the energy information collected in the home, it is necessary to prepare energy consumption patterns, consumption factors, and savings management measures. Accordingly, the energy information analysis unit 70 finds a key (that is, an energy key factor) that is a major element of energy saving. That is, the energy information analysis unit 70 performs the energy pattern analysis based on the association rule for analyzing the energy consumption pattern. In this case, the energy information analysis unit 70 finds a main element of energy consumption in the home through mining of the energy situation such as energy leakage. Thereafter, the energy information analysis unit 70 provides energy management decision support so that the user can easily manage the energy based on the energy saving operation scenario and the management policy criteria according to the association rule-based analysis of data mining.

The subscriber location determiner 80 identifies a subscriber location within a specific radius (eg, within a radius of 10 km) for sharing analysis energy information based on friend registration information. In this case, the subscriber location determiner 80 uses the current location of the subscriber who applied for analysis energy information sharing as a center point and grasps the location of the subscriber (ie, a friend registered subscriber) existing within a specific radius from the center point. . Preferably, the subscriber location unit 80 operates in conjunction with a GPS location recognition system (not shown).

In other words, the subscriber location determiner 80 is controlled by the controller 100 in a process of sharing analysis energy information between subscribers in a short distance through sharing location information of subscribers through GPS information agreement. In the case of short-range houses, similar types of energy information can be shared with each other, so that more efficient analysis / feedback can be received.

The output unit 90 outputs analysis energy information.

The controller 100 controls all internal components of the energy management server 50. Preferably, the control unit 100 includes a data filtering unit 102 and a data classification unit 104. The data filtering unit 102 filters the input power usage information and subscriber information. The data classifier 104 classifies the power usage information filtered by the data filter 102 for each energy element and stores the energy usage information in the storage unit 60. The data classifier 104 stores the subscriber information through the data filtering unit 102 in the storage unit 60.

The control unit 100 will be described in more detail. Among raw data sensed from energy collection sensors (smart plugs, hubs, etc.) installed in a home, unreliable data may be transmitted due to sensor errors, network congestion, and interference. Accordingly, the controller 100 performs filtering and classifying to ensure the reliability and validity of data of the storage unit configured based on the energy information received from the user.

As a result, the data filtering unit 102 performs data filtering based on a data type sensing method, an important element definition, and threshold setting of the sensing information to ensure the reliability and validity of the input data. .

The data classifier 104 classifies energy elements for energy usage patterns, frequencies, locations, environments, and facilities in the home. The data classifying unit 104 utilizes characteristics such as a period of a sensor applicable to a home, a range of values, and the like. On the other hand, the data classification unit 104 uses a SVM (Support Vector Machine), Frequent Pattern, Sequential Pattern methods.

2) The gateway 20 sends energy information (ie, power usage information) from each smart plug 10a to 10n to the user's power management terminal 30 via wireless. Accordingly, the power management terminal 30 allows the user to receive a visual energy information monitoring service using the location information and augmented reality technology.

3) Then, the user uploads the energy information received from the gateway 20 to the energy management server 50 in order to share the energy information of other users subscribed. In this case, building type, building scale, life pattern analysis information, and the like, which are basic user information, are uploaded together with energy information and stored in the storage unit 60 of the energy management server 50. In the embodiment of the present invention, the various energy information collected by the gateway 20 is uploaded to the energy management server 50 only when it is determined that the user may upload the power management terminal 30. That is, the energy information collected by the gateway 20 unconditionally is not immediately uploaded to the energy management server 50, but is uploaded only after the user inputs a signal indicating that the energy information may be uploaded.

In addition, the user may share energy saving information between users by using energy saving information tips for efficient service of user information sharing, and allow others to benchmark their energy information. When sharing energy information, the social network (facebook, me2day, twitter, etc.) synchronization of the account further spreads the sharing of the information.

4) The user operates the power management terminal 30 to request analysis energy information. Accordingly, the energy management server 50 by the energy information of the subscribed users by location (to share the energy analysis information between the subscribers in the near by sharing the location information of the subscribers through the GPS information agreement) In addition, the information is analyzed again by acquaintance list ('friend registration' list for smooth sharing of energy saving information tips), building type, and building size.
