specific Embodiment 1

[0090] This embodiment illustrates the situation that the fast networking method described in the present invention is used for intelligent lighting of street lamps based on power line carrier communication. use as figure 1 In the striped distribution of street lamps shown, it is assumed that the electrical distance for stable communication is 3 lamp segments.

[0091] Using the method of the present invention to form a network, the process is as follows:

[0092] Step 1: The master node with an ID number of 0 initiates a "master node networking" broadcast command to all slave nodes in the system, and the nodes with ID numbers of 1, 2, 3, 4, 5, 6, 7, 8, 10, and 11 Respond to the broadcast.

[0093] Step 2: After the master node confirms, these 10 nodes join the network as the first layer of relays.

[0094] Step 3: The slave nodes sequentially send the "slave node networking" broadcast command to complete the networking of its own subnet and the selection of associated node...

Embodiment 1

[0098] Embodiment 1 Using the power line networking method provided by the present invention, the networking is efficient, the network structure is clear, the invulnerability is strong, and the system communication efficiency is high. On average, each relay node manages two slave nodes, which avoids the problem that some relay nodes are more vulnerable to damage caused by using a single node as a relay.

specific Embodiment 2

[0099] This embodiment illustrates the method for rapid networking described in the present invention, which is applicable to the situation based on the complex topology of the power distribution network. In this embodiment, a 100*100 coordinate area is set, and 41 carrier nodes are randomly distributed in the area. The master node is No. 0, and 1-40 are slave nodes. The communication distance between nodes changes randomly and dynamically in different ranges. to simulate varying communication qualities. The electrical distance for stable communication is taken as 20 to 25. Due to the relatively complex structure of the distribution network and the presence of electrical nodes joining and exiting the network, in order to ensure communication efficiency, the upper layer nodes are selected first for the associated nodes, followed by the same layer nodes.

[0100] Use matlab to carry out the simulation experiment, and compare with traditional clustering algorithm and ant colony a...

Abstract

The invention provides a rapid networking method for power line carrier communication and specific implementation steps thereof, and aims to solve the problems of low networking efficiency, complex network structure and poor reliability in a power line carrier communication system. Compared with a conventional networking way, the rapid networking method provided by the invention has the advantages that a node association process is synchronously performed in the processes of completing hierarchical management and forming a system route, and a node association table is formed, so that the communication reliability of the system is ensured while the networking efficiency is increased. The local reconstruction range of a network is small; the efficiency is high; and the self-healing ability is high. The rapid networking method is suitable for data communication of a power line carrier communication system.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a fast networking method applicable to but not limited to power line carrier communication. Background technique [0002] With the rapid development of the global economy, the expansion of the scale of power grid construction, the increasing requirements for the quality, safety and intelligence of power consumption, and driven by the awareness of energy conservation and environmental protection, the development and construction of smart grid has become a world-recognized development trend. As an important branch of smart grid communication technology, power line carrier communication (PLC) technology uses the existing widely distributed power distribution network as the transmission medium, which has the advantages of fast construction speed, wide coverage, low investment, and no need for rewiring. It is suitable for A variety of application services in the smart grid, s...
