[0053] DETAILED DESCRIPTION One. A quasi-cobweb fractal networking method for low-voltage power line communication. In a low-voltage power line carrier communication system, a quasi-cobweb hierarchical fractal networking method can be used to realize the networking process of nodes in the network. The quasi-three-dimensional spider web model is composed of master nodes and slave nodes. Slave nodes include relay nodes and terminal nodes, such as Figure 1 to 3 Shown. Compared with the plane spider web model, this model can more accurately reflect the topological structure of the real low-voltage power line network. Therefore, the present invention equivalents the low-voltage power line communication logic network to a network composed of multiple single-layer quasi-three-dimensional spider webs, such as Figure 4 to 5 Shown.

[0054] In order to effectively explain the quasi-cobweb hierarchical fractal networking method, firstly, the node time slot function is explained.

specific Embodiment

[0070] The following method can realize the networking process of the quasi-cobweb fractal network of low-voltage power line carrier communication.

[0071] First, the master node first allocates two time slots for itself. In the first time slot, the master node will correct the frequency offset with the slave node. In the second time slot, the master node will send a data frame allowing the node to register to the slave node within the communication range. When the slave node is successfully registered, the master node will respond. In the convergence area, the master node stores the registered slave nodes in the topology table and assigns TEI to them. After the convergence process is over, the master node allocates time slots to the registered slave nodes, and the slave nodes that have obtained the time slots start networking in the order of time slot allocation. In the first time slot, the slave node performs frequency offset correction with other slave nodes within the comm...

Abstract

The invention provides a standard spider-web fractal networking method for low voltage power line communication, and relates to a standard spider-web fractal networking technology for low voltage power line communication. The standard spider-web fractal networking method for low voltage power line communication solves the problem that a current networking method has the disadvantages of being low in the networking efficiency, being low in the reliability and being low in survivability. The method comprises: a main node distributes two time slots for the main node, and then in the first time slot, the main node corrects the frequency offset between the main node and slave nodes. In the second time slot, the main node sends a data frame allowing registration of nodes to the slave nodes within the communication range. When the nodes register successfully, the main node can give a response. In a convergence area, the main node stores the registered slave nodes in a topology table and distributes TEI for the slave nodes. When the convergence process completes, the main node distributes time slots for the registered slave nodes, and the slave nodes which acquire the time slots can perform networking according to the distribution sequence of time slots. The standard spider-web fractal networking method for low voltage power line communication is suitable for a low voltage power line communication field.

Description

Technical field [0001] The invention relates to a quasi-cobweb fractal networking technology for low-voltage power line communication. Background technique [0002] With the continuous improvement of network efficiency and network reliability requirements for low-voltage power line carrier communication, the networking algorithms adopted at this stage, such as flooding algorithm, clustering algorithm, ant colony algorithm, planar spider web algorithm, etc., also have the following problems : [0003] 1. The more prominent problem of the current flooding networking method is: when the number of nodes in the network increases, the collision probability of networking frames received by the nodes will increase, resulting in relatively low networking efficiency between nodes. [0004] 2. The clustering networking method is that after the source node selects the cluster head node by a certain mechanism, the remaining nodes are gradually networked through the cluster head node. However, t...
