Problems solved by technology

However, the power line environment is dynamically changing, and it is difficult to select the position of the bridge node. At the same time, the communication rate of the narrowband power line carrier is low. Using it as a bridge of the broadband power line carrier network will affect the data transmission efficiency of the entire network.

Abstract

The invention relates to a low-voltage broadband power line carrier communication unit and a networking method. The communication unit comprises a processor and a broadband carrier baseband module; The processor realizes a broadband power line carrier communication network protocol stack; The broadband carrier baseband module provides a high-speed channel and a low-speed channel at the same time.the high-speed channel modulates and demodulates a carrier signal by using an OFDM mode; the low-speed channel modulates and demodulates a carrier signal in a direct spread spectrum mode; During networking, a station to be networked selects one channel from a high-speed channel and a low-speed channel of the coordinator as a working channel by taking the channel speed and the channel quality as reference factors, taking the channel speed priority as a principle or taking the channel quality priority as a principle. According to the invention, the network hierarchy is reduced, the one-time communication success rate is improved, and the low-voltage broadband power line carrier transmission efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of low-voltage power line carrier communication, and in particular relates to a communication unit integrating OFDM communication mode and spread spectrum communication mode and a network networking method for collecting low-voltage power distribution information based on the communication unit. Background technique [0002] Power Line Carrier Communication (PLC) technology is a communication method that uses power lines as a communication medium to transmit data information. This technology converts the original signal into a high-frequency signal through modulation and loads it on the power line for transmission. At the receiving end, the modulated signal is taken out and demodulated through a filter to obtain the original signal and realize information transmission. Through the power line carrier communication technology, the power company can obtain the user's electricity consumption information and even...
