A meter reading method for energy metering network

Abstract

A meter reading method for an energy metering network, the energy metering network includes a central node and N subnodes attached to the central node, each subnode has a unique unicast address in the network, and the central node triggers the meter reading process A specific superframe structure, and through the sub-nodes in the whole network connected node set to exchange information with each sub-node in the network, the central node and sub-nodes receive / send signaling and messages on their respective time slots during meter reading , the central node dynamically allocates the data time slots in each superframe according to the resource application status of the child nodes, and through the distributed and centralized joint on-demand allocation of time slot resources, the downlink broadcast of the entire network meter reading command can be quickly realized The efficient upstream transmission of metering data of each sub-node improves the efficiency of meter reading in the whole network and improves the performance of meter reading.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for reading meters in the whole network of an energy metering network. Background technique [0002] Strengthening energy metering management and improving energy utilization is the most effective way to reduce resource consumption and protect the environment, and it is also an important part of developing an energy-saving society. For the energy supply and management department, it is hoped that the efficient and fine management of the entire energy system can be realized remotely through the energy metering network. Therefore, the entire network needs to have functions such as energy consumption reporting, billing, and network monitoring data reporting, laying the foundation for highly informatized and automated management of the entire energy system. In the energy metering network, the signal transmission power of communication nodes is strictly lim...

[0006] 3. The uniqueness of the business destination node: the destination node of all the business data reported by the slave node is the master node, which will lead to local congestion

From the above network service characteristics, it can be seen that in the scenario where the number of network nodes is large and the service load is heavy, although the free competition CSMA channel access protocol based on channel monitoring and random backoff mechanism uses random backoff mechanism in the signal transmission process , but each signal transmission has a certain risk of collision. These risks will continue to accumulate during the multi-hop transmission process of the signal, resulting in a poor transmission success rate of the multi-hop signal. The source node needs to continuously retransmit the signal, which will aggravate Network traffic load and risk of signal collision, so the overall throughput performance of the network will drop rapidly
