Abstract

The invention discloses a local routing reconstruction method in a power line carrier communication network of a low-voltage electric distribution network, which relates to the field of power line communication and solves the problems of low efficiency of reconstruction, poor accuracy in reading meters and low utilization rate of channels of a node routing reconstruction method in the existing automatic meter reading system. In the method, an automatic meter reading system network layer and a MAC (Media Access Control) layer are analyzed and researched, after networking via a special network structure, namely an artificial logical spider-web, a central node in a sub-network is responsible for rerouting local blind spots of the sub-network, and is free from executing the routing reconstruction for all the nodes in the network, so that time for searching routing is saved, and communication efficiency and reliability are improved. The method provided by the invention is suitable for routing reconstruction in the power line carrier communication network of the low-voltage electric distribution network.

Description

technical field [0001] The invention relates to the field of power line communication, in particular to a route reconfiguration method. Background technique [0002] After the artificial cobweb networking of the MAC layer of the electric power automatic meter reading system is completed, due to serious channel interference, the terminal nodes in each subnet may still fail to communicate with the central node. In this case, a reliable and efficient blind spot rerouting method is very important to ensure the service quality of the entire automatic meter reading system. Currently, there are mainly the following two routing reconfiguration technologies for nodes. [0003] The first is the power line communication routing algorithm based on the idea of ​​clustering. The power line communication clustering algorithm mainly includes the network initialization algorithm and the network reconfiguration algorithm, which can effectively expand the communication radius of the power lin...
