Based on 230mhz power wireless private network smart meter direct mining built-in communication warehouse

Abstract

The invention discloses a built-in communication warehouse based on a 230MHz electric wireless private network intelligent electric meter direct collection, and the invention relates to a communication chamber of an electric energy meter. At present, the built-in communication warehouse is mainly used for local communication. After data collection, it needs to be forwarded to the business master station through the concentrator. The network structure is complex, requiring many network devices, poor network security, and timeliness cannot be guaranteed. The present invention is located in an electric meter, which includes a housing, an antenna module and a main control unit, a power supply module, a communication module, a carrier module, and a security chip module arranged in the housing; the technical scheme passes through a 230MHz power wireless private network without using Concentrator forwarding, directly connected to the business master station, reducing intermediate links, improving data collection efficiency, and flattening the network structure; adopting ring identification technology combining carrier communication and wireless private network, one-way carrier communication reduces carrier interference and improves data identification rate ; After the carrier communication is completed, the module enters the dormant state to reduce energy consumption and line loss.

Description

technical field [0001] The invention relates to a communication chamber of an electric energy meter, in particular to a built-in communication chamber for direct collection of an intelligent electric meter based on a 230MHz electric wireless private network. Background technique [0002] At present, based on the smart meter of the State Grid, there are two modes of communication warehouses: microgrid or power line carrier. The network topology is as follows: figure 1 As shown, the communication warehouse is used for local communication. The collection of electric energy and electricity information needs to be forwarded through the concentrator to realize the data back to the master station. The collection process is long, the network structure is complex, and the collection efficiency is low. The master station cannot manage a single electric meter. , unable to meet State Grid's needs for deepening the application of smart meters. The built-in LoRa module used in the market...

[0002] At present, based on the smart meter of the State Grid, there are two modes of communication warehouses: microgrid or power line carrier. The network topology is as follows: figure 1 As shown, the communication warehouse is used for local communication. The collection of electric energy and electricity information needs to be forwarded through the concentrator to realize the data back to the master station. The collection process is long, the network structure is complex, and the collection efficiency is low. It is impossible for the master station to manage a single electric meter. , unable to meet State Grid's needs for deepening the application of smart meters

The LoRa built-in modules used in the market are mainly used for local communication. After data collection, it needs to be forwarded to the business master station through a concentrator. The network structure is complex, requiring more network equipment, poor network security, and multi-layer data transmission leading to communication performance degradation; Using power line carrier technology for data transmission, there are problems such as limited transmission distance and poor anti-interference

At the same time, the wireless public network communication is used between the concentrator and the master station, which not only has poor transmission security, but also cannot guarantee timeliness
