Description

System and method for creating virtual UI & P using discrimination information of consumer electronics

The present invention relates to a system and method for generating a universal plug and play (UPnP) using discrimination information of a consumer electronic device. More particularly, the present invention uses a characteristic of a current consumed by a consumer electronic device connected to a smart outlet. The present invention relates to a system and method for generating a virtual UPnP using a type of the consumer electronics determined.

Various efforts have been made to reduce CO ₂ emissions, which are pointed out as the most representative cause of global warming. Due to these efforts, various researches on energy saving technologies are under way.

In addition, various technologies related to smart outlets have recently been developed as a method for managing home energy. Inside the smart outlet, there is a module that can measure current and voltage in real time, so you can measure the real-time power consumption of consumer electronics plugged into the outlet. In addition, there is a built-in electric relay (electric relay), so that the function to cut off the current according to the purpose.

In this regard, Korean Laid-Open Patent Publication No. 2011-0131782 (name of the invention: a method and system for providing context-aware advertisement service for power usage of home appliances) is a method of receiving information on the amount of power used by each of a plurality of devices transmitted from a gateway. And determining a device on which a change in the amount of power used has occurred based on the information on the amount of power used, and transmitting the advertisement content corresponding to the determined device to the user terminal. I am suggesting a method. As such, a method of determining a device based on the amount of power used by the device is disclosed.

In addition, technologies for discriminating consumer electronics based on existing current information may be classified into two types. Single source detection (SSD) technique that collects current information in the home from smart meters to be installed in each home and detects consumer electronics plugged into the outlet of the household, and attaches and discriminates a specific module attached to each outlet There is a source detection (MSD) technique. The SSD technique is easy to install because only an additional smart meter needs to be installed, and the MSD technique requires an additional module to be attached to each outlet, resulting in relatively high installation costs. However, because SSDs detect consumer electronics by measuring the current used in the home and then checking the specific current pattern of each consumer electronics, it requires a complicated manning machine technique, which requires time and detection. The disadvantage is that it requires the power used by the equipment.

The problem to be solved by the present invention is to propose a method for determining the consumer electronics by analyzing the state of the consumer electronics connected to the outlet.

Another problem to be solved by the present invention is to propose a method in which a virtual UPnP device for a determined consumer electronic device can be used to utilize a PUnP network function even for a device that cannot utilize the UPnP function.

To this end, the system for generating a virtual UPnP of the present invention measures and provides the amount of current supplied to the consumer electronics for a set time from the time when the variation occurs when the variation of the current supplied to the connected consumer electronics is greater than or equal to a predetermined value. The type of the consumer electronics is determined by comparing the smart outlet, the size of the current provided from the smart outlet, and the characteristic information of the current consumed in each of the pre-stored consumer electronics. The device type, model icon, It includes a home server for generating a virtual UPnP for the consumer electronics using the meta information including at least one of the service list.

The current detection module 112-1 determines whether a sudden change in the state of the supplied current occurs using the provided current information (eg, power on / off, TV channel change, etc.). If a sudden change occurs, the current detection module 112-1 provides information about this to the current shape module 112-2. The current shape module 112-2 extracts various current information from the current information collected after the sudden change. For example, the current shape module 112-2 extracts a peak current (Peak current), an average current (Average current), an effective current (RMS current), an intermittent current (CF current), and a leakage current (FF current). The current shape module 112-2 provides the extracted current information to the home server 120.
