The modulation /demodulation of electric-power wire communication signal, the modulus/digital to analog conversion of power line modulated signal, output signal drive amplification, reception
Signal bandpass filtering and low noise amplification, demodulation after electric-power wire communication signal be converted to ethernet communication signal or with
Too Network Communication signal modulation is electric-power wire communication signal.Specifically, 1 point of the power-switching circuit be AC-DC conversion unit and
Alternating current is converted to after exchange electricity suppl is obtained by exchange output unit, power-switching circuit 1 by AC-DC conversion unit
Direct current or directly exchanging electricity output.Wherein, alternating current is converted to direct current via the alternating current in AC-DC conversion unit
Low-voltage DC is exported after the working cell conversion of electric part, and the low-voltage DC is being carried after voltage stabilizing, rectification and step-down
Supply CPU, storage circuit and PLC transmission circuits are used.Alternating current then directly can be exported.
Further, the peripheral interface units at least include WAN mouths, at least one LAN mouths, Pairs buttons and instruction
Lamp.Wherein, described WAN mouths are used directly for connecting the front network input equipments such as light cat；Described Pairs buttons are main
For main cat part in Homeplug and from the pairing between cat part；The indicator lamp can be the working condition of current device
And power supply output state.
Further, the power line communication circuits course of work：Data when sending, using modulation technique by number of users
