Power line carrier communication based system, bridging node and method

Abstract

The present invention relates to the field of communication technology and discloses a power line carrier communication based system, bridging node and method. In doing so, the success rate of communication can be ensured. The power line carrier communication based system of the invention comprises a first sub-net and a second sub-net. The internal nodes of both the first sub-net and the second sub-net communicate through a power line carrier channel, wherein the carrier chip of a first bridging node of the first sub-net is connected with a first wireless module while the carrier chip of a second bridging node of the second sub-net is connected with a second wireless module. A wireless channel is established between the first wireless module and the second wireless module.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a system, bridge node and method based on power line carrier communication. Background technique [0002] In recent years, power grid companies have promoted informatization and intelligent reforms, and the concept of smart grid has quietly emerged. Smart grid applications are very extensive, including remote meter reading, load control, transformer monitoring, remote measurement of power quality, security monitoring, time-of-use tariffs, Dynamic billing and other various value-added services, etc. The physical basis of building a smart grid is the electricity consumption information collection system, and the core foundation of the electricity consumption information collection system lies in communication. Most of them adopt RS-485 wiring, narrow-band low-frequency power line carrier or wireless communication methods. These meter reading systems either have too ...

AI Technical Summary

Problems solved by technology

At present, the domestic power grid low-voltage power consumption information collection market mainly adopts the power line broadband carrier communication solution based on the international standard Homeplug standard of Qualcomm and Huawei HiSilicon. The communication frequency range is 2-30MHz, and the communication rate can reach up to 1Gbps. The communication frequency is high, and the attenuation is relatively large when passing through the power compensation cabinet, capacitance compensation cabinet, leakage protector and buried wire, thereby shortening the communication distance between points and reducing the success rate of meter reading
