摘要

Disclosed in the present invention is a carrier communication method, device and system of low-voltage power lines, wherein, the carrier communication method includes: acquiring communication data comprising user data transmitted during communication and frame control data for assisting decoding of the user data; encoding the communication data using orthogonal space-time block codes and generating multipath transmission signals, in the case of unknown channel status; and transmitting the multipath transmission signals to an electric energy meter respectively via three-phase power lines. The present invention fully employs the characteristic of distinct inter-phase coupling of electrical signals at medium-and-high frequencies along power lines, and adopts various space-time encoding and decoding technologies, thereby improving the reliability of power line carrier communication between the concentrator and the electric energy meter.
