This paper proposes that a power line carrier modem with a USB interface is composed through adding the MCU CY7C68013 with USB2.0 interface to a power-line carrier module
which can conveniently realize the automation and network of household appliance control. In this thesis
the hardware constitution of the system
the architecture of intelligent appliance network and the design of network control protocol are discussed in detail. And the diagrams of main software procedure of the carrier communication are given.
