Description
The present invention relates to home network technology, and more particularly, to an apparatus and method for analyzing, extracting and managing an abnormal electronic device in a home network.
With the development of communication devices, network technologies, etc., the concept of home network has emerged. The home network forms a plurality of devices (eg, a computer, a television, a refrigerator, etc.) installed in a home as one network, and controls each device according to a user's command. In order to implement such a home network, home electronic devices must be smart devices.
There are many differences between a smart device and a general device, but the only one is the communication function. The smart device performs a series of processes, such as collecting information through a communication function and interacting with another device or a person and requesting the server to process the information. In other words, the communication function, that is, the presence of the communication module and its software may be a feature of the smart device.
On the other hand, both smart devices and general devices have in common that they are electronic devices. That is, there is a feature that operates using electricity. Any device requires power to operate. At present, smart devices with computing power and communication functions and general devices are not working together, and this configuration will be maintained as the future develops. In the future, as analog and digital coexist, the use of general electronic devices will coexist.
Meanwhile, 3D printers have been commercialized and used in recent years. The 3D printer is a device that can produce a three-dimensional three-dimensional article according to a design drawing input in advance. Using these 3D printers, pistols and various electronic devices can be manufactured in-house. In addition, in recent years, various types of electronic devices have been widely used, and a method for electric power trading has been proposed while power supply does not keep up with electric power demand due to exhaustion of energy resources. Therefore, in such a power environment, a problem of illegal charging or electric power hacking of an electric vehicle may occur due to the theft of electric power using a 3D printer or the like. In particular, when manufacturing and using an electronic device that is not authorized as a 3D printer in the home, the possibility of a fire due to overheating or overload of the electronic device may be increased.
Accordingly, in recent years, a technique such as a multi-tap for measuring the power consumption of electronic devices has been proposed, but this requires a dedicated multi-tap or a plug. The configuration of these separate accessory-type measuring devices for monitoring power usage can be a hindrance to consumer dissemination and the proliferation of services as commodities.
The present invention has been proposed to solve the above problems, abnormal operation by recognizing a general electronic device and a smart electronic device by observing the usage pattern of power that can only be used for all electronic devices without a separate measuring device in the home network An object of the present invention is to provide an apparatus and method for monitoring and managing an electronic device.

The generation unit may set the meter instance to recognize the non-smart devices as one virtual electronic device in each group.
The determination unit may extract a pattern of past power usage of the electronic device received by the receiver as a security pattern.
The determination unit may divide a predetermined period into a plurality of sections and extract a direction vector of power consumption in each section as a security pattern.
The determination unit may use a direction vector of a portion of the plurality of sections as a security pattern.
The determination unit may update the security pattern at regular intervals.
The control device, the collecting unit for collecting the sensing information from the sensor; And an analysis unit configured to analyze an exception event of power usage based on schedule information and the sensing information, wherein the determination unit may exclude the power consumption at the time when the analysis event is analyzed as the exception event from the pattern comparison. Can be.
The analyzer may request and receive calendar information from the calendar terminal when the sensing information is collected by the collector.
