Networking method and meter reading method of energy metering network

Abstract

The invention discloses a networking method and a meter reading method of an energy metering network. The main node triggers a specific superframe structure in a networking or meter reading process; During networking, a master node sends a network access invitation signal to a slave node on a master node signaling time slot of a networking superframe. And the slave node receives / sends the signaling on the signaling time slot belonging to the slave node in the networking superframe, and the master node guides the slave node which does not access the network to access the network quickly hop byhop and distributes short addresses, so that short-time dense network access of a large number of nodes and quick establishment of a network topology are realized. During meter reading, the main nodesends a whole network meter reading signal on a main node signal time slot of the meter reading superframe. The slave node receives / sends the signaling and receives / sends the meter reading data on thetime slot, belonging to the slave node, of the meter reading superframe. In the meter reading process, the distribution characteristics of short addresses of the slave nodes are combined, and downlink whole network broadcasting of a whole network meter reading command and uplink efficient transmission of metering data of the slave nodes can be rapidly realized through distributed and centralizedjoint on-demand distribution of time slot resources.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a networking method of an energy metering network and a meter reading method. Background technique [0002] In order to better realize energy saving and consumption reduction, the scientific, standardized and automated energy metering management (water, electricity and electricity) has attracted more and more attention from all parties. For the energy supply and management departments, the diversified needs of users and the development of their own management also require efficient and refined management of energy consumption, such as realizing time-of-use billing of energy consumption, so that the system can record within a specified time User consumption can be managed on a household basis and charged in a timely manner. It can detect the resource utilization of the system in a timely manner and perform peak control, and use comprehensive and scientific techni...

[0007] 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

[0008] From the above business characteristics, it can be seen that there is a big difference between the energy metering network and the traditional distributed multi-hop network. In addition to the uniqueness of the business, the communication protocol of the conventional distributed multi-hop wireless network does not have the same communication effect in the energy metering network. For example, the CSMA channel access protocol suitable for the light network traffic load model has poor communication effect in the energy metering network
