Wireless networking method of electric power meter reading system and electric power meter reading device system

Abstract

The invention provides a wireless networking method of an electric power meter reading system and an electric power meter reading device system. The method comprises the following steps of dividing the electric power meter reading system into a plurality of clusters according to the field intensity distribution of each node in the electric power meter reading system, wherein each node in the electric power meter reading system is an electric meter; determining a cluster head node and at least one cluster member node in each cluster, wherein the cluster head node is used for managing routing information of the cluster member node and transmitting the routing information variation of the cluster member node to a concentrator. By adopting the wireless networking method and the electric power meter reading device system, the technical problems in the prior art that more time is consumed for networking and routing update because the routing information of all nodes in the system is managed by the concentrator can be solved, and a technical effect of shortening the networking and route updating time can be realized.

Description

technical field [0001] The invention relates to the technical field of data services, in particular to a wireless networking method of an electric meter reading system and an electric meter reading equipment system. Background technique [0002] The electricity consumption information collection system is mainly used to realize the automatic meter reading and automatic control of the electric energy meters of the majority of industrial, commercial and residential users, and is the basic project for building a smart grid. However, the core issue that currently affects the automatic meter reading and automatic control of the electricity consumption information collection system lies in the last mile, that is, the communication between the concentrator and the electric meter. The so-called concentrator refers to the collection of data from each collection terminal or electric energy meter , and process and store, and at the same time, it is a device that can exchange data with ...

Problems solved by technology

[0006] The existing centralized meter reading system has the following defects: Due to the centralized routing management strategy, all networking processes must be completed in a single networking channel, and the superframe structure is used in the networking process for unified time slot allocation and networking of the entire network , the networking time is proportional to the capacity of the network nodes. In the case of the data transmission rate commonly used in micro-power wireless communication of 9.6kbps, the networking time required to complete the networking with a network scale of 1024 nodes under ideal conditions is 90 minutes. The network time is very long, which has a negative impact on the installation and commissioning progress of the initial installation of the user's electricity information collection system; further, if the location of a certain node changes or the surrounding environment changes, the routing of the entire network changes , since the routing information of all networks is uniformly controlled by the central node in the concentrator, it is necessary for the central node to update the routing of the entire network, which takes a long time, so only a fixed time can be spared every day for the entire network route maintenance
