1. Field of Invention
Various embodiments of the present disclosure relate to predicting electricity usage, and more particularly, to an apparatus and method capable of analyzing the amount of electricity used in a smart home environment, thereby obtaining a home electronic appliance usage pattern of a user and predicting a future usage pattern.
2. Description of Related Art
In recent days where the concept of smart home based on wired/wireless communication networks is being generalized, users have come to expect more convenient and intelligent services. However, in reality, legacy home electronic appliances still account for most of home electronic appliances, and smart home electronic appliance environments also have problems in that home electronic appliance manufacturers use different communication protocols, and that there is no profile for managing information of home electronic appliance, and therefore, it is difficult to develop integrated and intelligent services.
Conventional systems sense behaviors of users and changes in a home environment through sensors in order to perceive the situation in the home environment or collect operational information of home electronic appliances being transmitted through individual protocols to perceive patterns of the users. The technology of perceiving a home situation through environment sensors is a situation perceiving technology that focuses on the users rather than on the home electronic appliance. The technology of collecting and analyzing operational information of a home electronic appliance through protocols has a disadvantage in that it can only be applied when the home electronic appliance supports those protocols.
Furthermore, most conventional systems analyze comprehensive operational situations inside a home rather than usage patterns of each home electronic appliance, and thus an overall pattern model of the home and a usage pattern model of each home electronic appliance need to be defined and analyzed in different formats.
Furthermore, most conventional systems use technologies of perceiving appliances or statuses of the appliances using a smart grid environment.
Therefore, various embodiments of the present disclosure are directed to resolve the aforementioned problems, that is, a purpose of the present disclosure is to analyze the amount of electricity usage of a home electronic appliance so as to understand the status of the home electronic appliance, and to analyze information on the status of the home electronic appliances accumulated based on the usage pattern model of each home electronic appliance, thereby analyzing a home electronic appliance usage pattern that can be used in various smart home services.
According to an embodiment of the present disclosure, there is provided a network-based home electronic appliance usage predicting apparatus including an information collecting unit configured to receive electricity usage information of at least one home electronic appliance through a network; an information database configured to store the electricity usage information received by the information collecting unit; and a pattern analyzing unit configured to analyze a usage pattern of a corresponding home electronic appliance based on the electricity usage information stored in the information database, generate information on predicted electricity usage of the home electronic appliance based on a result of the analysis, and store the information on predicted electricity usage of the home electronic appliance in the information database.
In an embodiment, the network-based home electronic appliance usage predicting apparatus may further include a predicted information providing unit configured to output the information on predicted electricity usage of the home electronic appliance stored in the information database.
In an embodiment, the predicted information providing unit may be a display apparatus.

In an embodiment, the pattern matching module may include a usage variable generating unit configured to define variables to be applied in order to generate a usage pattern model; a pattern reference generating unit configured to generate a pattern reference to be actually compared according to characteristics of the home electronic appliance based on the usage variable; and a pattern applying unit configured to apply the discretized electricity usage information to the pattern reference.
In an embodiment, the usage pattern reference of the home electronic appliance may include at least one of a date of usage of the home electronic appliance, frequency of usage of the home electronic appliance, and type of usage of the home electronic appliance.
According to another embodiment of the present disclosure, there is provided a network-based home electronic appliance usage predicting method including receiving electricity usage information of at least one home electronic appliance through a network; storing the received electricity usage information in a database; analyzing a usage pattern of a corresponding home electronic appliance based on the stored electricity usage information; and generating information on predicted electricity usage of the home electronic appliance based on a result of the analysis.

In an embodiment, the network-based home electronic appliance usage predicting method may further include outputting the information on predicted electricity usage stored in the database.
In an embodiment, the analyzing a usage pattern of a corresponding home electronic appliance based on the stored electricity usage information may include analyzing the electricity usage information in a clustering method to generate a status cluster of the home electronic appliance; and comparing information on actual electricity usage based on the status cluster of the home electronic appliance.
According to the aforementioned system and method of the present disclosure for predicting usage of a home electronic appliance based on the amount of electricity used, since in the current situation where smart home environments are being widely distributed, infrastructure of a smart grid is being established most rapidly, by providing this apparatus and method for analyzing data of the amount of electricity usage that may be obtained most easily so as to analyze a usage pattern of the home electronic appliance, there is an advantage of perceiving the situation of electronic appliances at home while resolving the difficulty of obtaining information on legacy home electronic appliances and the problem of compatibility of protocols between different manufacturers of home electronic appliances.
