Home gateway for controlling different brand devices in a home network system using the power line communication

摘要

The present invention relates to a home gateway device capable of integrated control of heterogeneous products in a home network system using power line communication, and in particular, a power supply unit receiving power signals transmitted through the power line communication to supply power to the home network; A PLC processor which receives a power signal from the power supply and demodulates and processes the signal to extract a communication signal for power line communication; A protocol conversion unit for checking a protocol of each home appliance inputted to the home gateway and converting a signal transmitted and received with the home appliance into an integrated protocol capable of integrated processing; And a CPU for transmitting the signal processed by the PLC processor or the protocol converter to an external processor.;PLC, home network, home gateway, heterogeneous, protocol
