Abstract

The invention discloses a power line communication routing method and device. The method comprises the following steps: calculating a path weight between relay nodes in a power line communication network; calculating a first optimal routing path of the power line communication service by adopting a K shortest path algorithm according to the path weight; and selecting the first optimal routing path meeting the node routing condition for routing. According to the invention, high-capacity reliable operation and low-delay transmission of the service of the power line carrier communication network can be ensured.

Description

technical field [0001] The present application relates to the technical field of power line communication, and in particular to a power line communication routing method and device. Background technique [0002] There are many deficiencies in power line carrier communication. Since the transmission line of the power line is mainly used to transmit electric energy, the transmission of signals is not so ideal. There are a wide variety and a large number of electrical devices associated with the power line, which have high attenuation to the carrier signal, and the attenuation is not uniform throughout the power line transmission process. Because of the mismatch of transmission impedance, it will also cause reflection and refraction of the signal during transmission, which will produce multipath effect. In addition, the random switching of electrical equipment will also bring complex noise. Poor shielding of power lines will also cause greater interference to signal transmis...
