Problems solved by technology

[0004] The communication between terminals for power consumption information collection mainly relies on power line carrier. The quality of power carrier communication is related to the power load. When the power load on the line becomes larger, the quality of carrier communication will decrease, reducing the success rate of communication between terminals.

Embodiment approach

[0050] As a preferred embodiment of the present invention, the terminal networking method for power consumption information collection based on power line carrier communication further includes the steps of:

[0051] S4. The networking terminal node recalculates several carrier signal attenuation values ​​respectively matched with the lines every other time period, and creates corresponding new carrier communication path information.

[0052] combine figure 2 , after terminal node 1 performs calculation and analysis, it is concluded that the carrier communication path of "line 1 → line 2" is the optimal carrier communication path. After creation, storage and communication, if any of terminal node 2, line 1 or line 2 If a fault occurs, communication is interrupted. At this time, through step S4: terminal node 1 recalculates several carrier signal attenuation values ​​that match the lines respectively every other time period and creates corresponding new carrier communication ...

Abstract

The present invention discloses a power line carrier communication-based electricity information collection terminal networking method. The method comprises the steps of pre-sending networking parameters; calculating, by a networking terminal node, a plurality of carrier signal attenuation values matching paths; and creating, by the networking terminal node, carrier communication path information and communicating with a to-be-networked terminal node, wherein the paths refer to all communicable paths between one to-be-networked terminal node and one networking terminal node, and the path load impedance is obtained through dividing a voltage of one communication path between one to-be-networked terminal node and one networking terminal node by a current. According to the method, the networking terminal node calculates the transmission signal attenuation value of the communication channel to analyze the channel quality, so as to select a high-quality network communication path, so that the communication success rate is high.

Description

technical field [0001] The present invention relates to the field of power line carrier communication terminal networking technology, more specifically, the present invention relates to a power line carrier communication based power information collection terminal networking method. Background technique [0002] The "Smart Grid" of the State Grid has been widely used all over the country. As a part of the Smart Grid, the electricity consumption information collection terminals are widely installed in urban and rural enterprises and residential users. [0003] The power consumption information collection terminal is mainly responsible for data collection, state quantity collection, power control, power control, and data interaction with the main station of the power consumption information system for the power user's smart meter. At the same time, an interconnection network is also formed between terminals, which is used for information sharing and file synchronization betwee...
