Embodiment Construction

[0026] In order to clearly illustrate the solutions in the present invention, preferred embodiments are given below and detailed descriptions are given in conjunction with the accompanying drawings. The following description is merely exemplary in nature and is not intended to limit the application or uses of the present disclosure. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0027] Such as figure 1 shown. A networking method based on power line carrier communication, the method comprising:

[0028] S101. Send a meter reading frame in the form of a flood frame to a target node, and record the sequence number of the frame when the meter reading frame is forwarded. The gateway node refers to a transit node between the power line carrier network and the external network, and functions as a gateway through which the power line carrier network can be managed.

[0029] The flood frame...

Abstract

The invention discloses a networking method based on power line carrier communication, which includes sending a meter reading frame in the form of a flood frame to a target node. When the upper limit is reached, the meter reading frame is forwarded; if the non-target address and the meter reading frame has been forwarded, it is judged whether it is the parent node according to the signal-to-noise ratio and signal strength, and if so, the parent node address, signal-to-noise ratio and Signal strength; if the signal-to-noise ratio and signal strength are higher than the threshold X1 at the same time, forward the meter reading frame including its own address, signal strength, signal-to-noise ratio and forwarding level; if the target node is the final address, according to the level comparison, Judge the better path and level, and select the lower level when the same signal strength and signal-to-noise ratio intervals appear. The invention aims at the nodes in the large-scale power line communication network, can realize fast copying, builds the network at any time, and has the advantages of high network adjustment efficiency.

Description

technical field [0001] The invention relates to the field of power line communication, in particular to a networking method and device based on power line carrier communication. Background technique [0002] Power Line Communication (PLC) is a communication method that uses power lines and their transmission and distribution networks as information transmission media. The traditional power line communication system uses narrowband power line communication technology, which is mainly used for long-distance communication and control tasks between power equipment. With the development of technology, the power line transmission bandwidth can reach up to hundreds of megahertz, which can be used for better data transmission and component network. Because the power network is widely distributed, power line communication has the advantages of no need for rewiring, convenient and flexible access, etc., it is a communication technology that is very suitable for user access networks. ...
