Abstract

The invention discloses a piece of power line communication equipment and a power line communication method, and relates to the field of terminals. The power line communication equipment comprises a power line communication interface, a universal serial bus interface and a signal coupling unit. The power line communication interface is connected with the signal coupling unit and is used for transmitting a signal to the signal coupling unit. The signal coupling unit is used for coupling or decoupling the signal. The universal serial bus interface is used for supplying power to the power line communication equipment. According to the invention, weak power supply is carried out based on the USB interface. On one hand, compared with strong power supply, power consumption of the equipment can be reduced, fewer transformers are required, the device cost is reduced, the product size is reduced, the difficulty in wiring design is reduced, the access threshold for equipment design and production is lowered, and the rise of the power line communication market is benefited. On the other hand, power supply interfaces are separated and an information interface is independently arranged, conductive interference on the power line communication interface is reduced, and the equipment can easily meet the electromagnetic compatibility certification requirements.

Description

technical field [0001] The present invention relates to the field of terminals, in particular to a power line communication device and method. Background technique [0002] G.hn technology is an indoor networking communication technology that can be transmitted on three media: telephone line, coaxial cable, and power line. It is also called "wired networking technology based on a common medium". [0003] G.hn power line communication equipment provides a convenient and fast home networking solution for services such as iTV and FTTH (Fiber to the Home, fiber to the home). iTV business uses broadband network as channel, TV as display terminal, integrates Internet, multimedia and communication technologies, and provides users with interactive video services such as on-demand and live broadcast. It is a brand-new broadband value-added service. [0004] However, traditional power line communication usually uses two power line adapters to supply power through the indoor power int...
