Power distribution network monitoring data intelligent transmission method based on mesh structure

Abstract

The invention discloses a power distribution network monitoring data intelligent transmission method based on a mesh structure, and the method comprises the steps: enabling each monitoring terminal ina power distribution network to serve as a node, and enabling each node to employ the mesh structure for networking; dividing a plurality of networking nodes into node clusters in the mesh network; if the multi-hop network exists in the node cluster, transmitting data by adopting learnable networking, and if the multi-hop network does not exist in the node cluster, transmitting data by adopting apolling mode; determining the priority of information transmission of the core node according to the grading of the core node; collecting the data uploaded by the core node and transmitting the datato a background server for information processing by the gateway; the problems that in the prior art, a mesh network structure is widely applied to a power distribution network, but along with continuous expansion of the scale of the mesh network structure, a multi-hop mesh structure has bandwidth reduction, network delay and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of electric power communication, and in particular relates to an intelligent transmission method of distribution network monitoring data based on a mesh structure. Background technique [0002] Wireless Mesh network is a wireless multi-hop mesh topology network with self-organization, self-management, self-healing capabilities, good security, high stability, large coverage, large bandwidth, zero tariff, flexible and convenient networking, etc. ; It is based on the many advantages of the mesh structure that the mesh network structure is widely used in the distribution network. However, with the continuous expansion of the mesh network structure, the multi-hop mesh structure has problems such as bandwidth reduction and network delay. There are many types of terminals required to be monitored in the distribution network, the geographical distribution is wide, the span is large, and a series of problems such as ...
