POWER LINE COMMUNICATION METHOD FOR TRANSMITTING DATA SIGNAL WITH SPLITTING OF POWER TRANSMISSION INTERVAL

摘要

PURPOSE: A power line transmission method is provided to reduce the transmission error of a data line by electrical noise and to increase the voltage of a data signal by separating a power line section. CONSTITUTION: An entire section for the transmission of power and data signal is separated into a power transmission section and a data transmission section. One data signal is loaded in the data transmission section. The data signal is transmitted to a load side. Voltage or current which is supplied to a load side is in a low state.
