Home network system and method adding/deleting domestic electric appliance to/from the same system

Abstract

A home network system and a method for adding and / or deleting home appliances thereto / therefrom. The home network system is constructed so that a plurality of home appliances can transmit and receive data to / from one another. The home appliances are assigned logical addresses, respectively. A plurality of power line modems are connected respectively to the home appliances to modulate and demodulate data transmitted and received over an internal network by the home appliances. A network master is provided to assign the logical addresses to the home appliances and a home address to each of the power line modems, respectively. Therefore, the home network system can be efficiently constructed, and a desired home appliance can be simply deleted from the internal network.

Description

technical field [0001] The present invention relates to a home network system and a method for adding / deleting household appliances to / from the system; more precisely, it relates to a home network system and a method for adding / deleting household appliances to / from the system, wherein the data transmission and receiving via the power line communication network, and logical addresses are effectively assigned to multiple home appliances or deleted. Background technique [0002] Generally speaking, a home network system is connected to an internal network built in a home, so that multiple home appliances in the system can send and receive data with each other via the internal network. Home appliances are controlled by data transmitted via an internal network. After the household appliances are controlled by the data received from the internal network, they output information about their respective controlled states to the outside so that they can be monitored from the outside....

AI Technical Summary

Problems solved by technology

[0005] However, a deficiency of the above-mentioned existing home network system is: if the internal network is not separately built in a family as mentioned above, but is built in a building including a plurality of offices or families, then it Inability to distinguish between multiple appliances connected to the internal network in the building

For example, if air conditioners are installed in the first and second offices respectively, and they both share a power line for communication, they will not be assigned a separate identity, such as a home address, etc., thus making it impossible to control them from the outside. The two differentiate and thereby control the
