WAKE UP APPARATUS FOR POWER LINE COMMUNICATION TERMINAL MODULE

摘要

PURPOSE: A wake-up apparatus for a power line communication terminal module is provided to generate a wake-up signal of interrupt signal type to wake up a microcomputer for system control at a power-down mode. CONSTITUTION: A PLC(Power Line Communication) extraction unit(100) extracts a PLC signal from a power line through a coupling circuit, and a PLC signal amplification unit(200) amplifies the frequency of the extracted PLC signal. If the amplified PLC signal is received, a wake-up signal generating unit(300) generates a wake-up signal. Through the wake-up signal, the microcomputer of the power-down mode wakes up.
