The power line microcomputer(3) adds telephone number information of the area to data outputted through the power line.

Description

Network System Using a Power Line Communication and Controlling Method for the Same}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network system using a power line and a control method thereof, and more particularly to a network using a power line such that the home appliance installed in a building is not controlled according to control information of a home appliance in an area where a home appliance installed in a building is not installed to transmit and receive data using the power line. It relates to a system and a control method thereof.

Recently, a plurality of home appliances in a home are connected through a home network, and power line communication (PLC) is widely used to remotely control home appliances in the home or to automatically report failures.

However, a power line that is built for power line communication is constructed in a dense residential area such as an apartment. In this case, a power line signal of one home is transmitted to the next door. Therefore, in order to limit the power line communication signal of each household to one household, an expensive blocking filter must be used, which greatly increases the cost.

In addition, in the case of the blocking filter, since the construction of the power line has to be carried out, it is cumbersome to newly construct a new part of the power line.

In order to avoid this, in the past, each device had to be assigned a unique number at the time of manufacturing the factory and set it again at the consumer's home, while starting a home server program for managing it. However, the general consumer who is not an expert cannot perform the setting of the unique number and start the home server program smoothly, and thus, the user cannot efficiently use the home appliance even when purchasing a networking-enabled home appliance.

The present invention has been made to solve the above problems of the prior art, the purpose of which is to set the phone number information of the area where the home appliance is installed as a home appliance that transmits and receives data through a power line through the phone number information The present invention provides a network system and a control method using a power line capable of separate control even when home appliances of other homes are connected through a single power line.

As shown in FIG. 1, a network system using a power line according to the present invention includes a plurality of home appliances H1 to Hn that receive power through a power line and simultaneously transmit and receive information on control and status of the power line and home appliances. And a plurality of power line modules (P1 to Pn) for connecting the plurality of home appliances (H1 to Hn) with the power line and simultaneously adding telephone number information of an area where the plurality of home appliances are installed to data output by the home appliance. It consists of.

In particular, as shown in FIG. 2, the power line modules P1 to Pn may include a coupling unit 1 for separating power and a signal input through the power line, and modulation of signals transmitted and received through the coupling unit 1. The demodulation and demodulation unit 2 performs demodulation, and the telephone number information included in the data inputted through the modulation and demodulation unit 2 is compared with the telephone number of the region where the home appliance H1 is connected, and the telephone number is compared. The telephone of the area where the home appliance is installed in the data transmitted only to the home appliance (H1) that the information matches the telephone number of the region where the home appliance is installed to the home appliance (H1) at the same time. It consists of the power line micom part 3 which adds number information.

In addition, the power line module (P1) is connected to the power unit (4) and the coupler (1) which functions as a power source of the power line module (P1) as a separate power is input through the coupling unit (1). Telephone number input means for inputting information about the telephone number of the region in which the driver (5) for amplifying the separated signal through the power line microcomputer (3) and the home appliance (H1) connected to the power line module is installed ( It is configured to further include 6).
