Abstract

The invention discloses a power line carrier communication device and method. Wherein, the power line carrier communication device includes: a power input unit, when the multi-phase switch is disconnected, obtains AC power from the upper port of the switch, and converts the AC power into DC power to provide electric energy for the target carrier unit; The DC power supply is converted to output AC power to supply power to the next-stage carrier communication device; when the multi-phase switch is turned off, the target carrier unit identifies the target phase of the next-stage carrier communication device according to the communication phase selected by the selector, and Establish a communication connection with the next-level carrier communication device, convert the power line carrier signal into a carrier digital signal and send it to the carrier controller, and output the carrier digital signal through the carrier controller.

Description

technical field [0001] The present invention relates to the technical field of carrier communication, in particular, to a power line carrier communication device and method. Background technique [0002] In related technologies, many devices and power grids use power line carrier communication technology, that is, PLC technology. PLC technology uses power lines as the physical communication medium, thereby saving the cost of network cables and optical fibers. Compared with wireless communication networks, it is not blocked by buildings. and other influences (the power line generally enters the building directly through the line), so it has unique advantages in distribution network communication. [0003] However, the current power line carrier communication has a great disadvantage, that is, when the power line switch is disconnected, due to the disconnection of the physical link layer, communication and power supply cannot continue to be realized, resulting in limited appli...
