Problems solved by technology

These nodes need to be manually designated, and the corresponding routing table items need to be manually set. When replacing the device or expanding the network, etc., it needs to be manually operated again, which is time-consuming and labor-intensive. The networking speed is slow and the maintenance cost is also high.
In addition, with the development of the current power line communication network, people have put forward higher requirements for the services carried on it, and the traditional method of specifying the relay is no longer applicable.

Embodiment 1

[0029] The characteristics of the networking mode of the low-voltage power line carrier communication system affect the networking strategy and implementation technology. The communication logic topology is complex and changeable. Because the low-voltage power line carrier communication network is affected by high The random switch access of various electrical appliances causes the communication channel to change drastically randomly, and the logical topology of the communication will also change accordingly. Therefore, the networking algorithm is required to have high invulnerability and strong self-healing performance; real-time Not demanding.

[0030] The function of the low-voltage carrier system is only to periodically read the user's power consumption data and exchange some other control information. The amount of communication data is small, the real-time requirements for the data are low, and most of the time is idle; it requires hardware and networking algorithms. As ...

Embodiment 2

[0079] refer to figure 2 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that it provides a test comparison of a low-voltage power line carrier communication system layered networking method, including:

[0080] In order to better verify and illustrate the technical effects adopted in the method of the present invention, this embodiment chooses to conduct a comparative test with the traditional networking method and the method of the present invention, and compares the test results by means of scientific demonstration to verify the advantages of the method of the present invention. real effect.

[0081] The traditional networking method does not provide the dynamic reconstruction and optimization method of routing, and its invulnerability and self-healing ability are poor. In order to verify that the method of the present invention has higher invulnerability and network reliability than the traditional metho...

Abstract

The invention discloses a hierarchical networking method for a low-voltage power line carrier communication system. The method comprises the following steps: completing the automatic hierarchical networking based on a communication quality optimization theory and a non-overlapping clustering hierarchical routing algorithm in combination with a corresponding communication protocol; taking a main station and substation terminals in a low-voltage power line carrier communication network as network nodes, performing logic layering according to a communication mode, and establishing an initial routing table; and performing optimization, updating and reconstruction strategy setting on the routing table based on communication quality until hierarchical networking and maintenance are completed. According to the invention, the main station and each substation terminal in the low-voltage distribution area are taken as network nodes, logic layering is carried out according to a communication mode, an initial routing table is established, and optimization, updating and reconstruction strategy setting based on communication quality are carried out on the routing table, so that automatic layering networking of low-voltage power line carrier communication can be realized in the above mode; the network reliability is effectively improved.

Description

technical field [0001] The invention relates to the technical field of layered networking of a power line carrier communication system, in particular to a method for layered networking of a low-voltage power line carrier communication system. Background technique [0002] The power line network has many branches, large scale, and long lines, which make the power line channel suffer from serious noise interference and signal attenuation, which reduces the reliability of point-to-point communication of user terminals. The purpose of carrier system networking is to improve the effectiveness of system transmission. Currently In-depth research has been carried out on the networking methods at home and abroad, and various networking methods have been proposed. [0003] So far, many people have conducted research on various dynamic networking methods. Such as various types of ant colony algorithm, "logical topology" method, routing algorithm based on clustering, etc. All of the a...
