Built-in communication bin based on 230 MHz electric power wireless private network intelligent electric meter direct collection

Abstract

The invention discloses a built-in communication bin based on 230 MHz electric power wireless private network intelligent electric meter direct collection, and relates to a communication bin of an electric energy meter. At present, a built-in communication bin is mainly used for local communication, data needs to be forwarded to a service master station through a concentrator after being collected, the network structure is complex, more network devices are needed, the network security is poor, and the timeliness cannot be guaranteed. The built-in communication bin is arranged in an electric meter, and comprises a shell, an antenna module, and a main control unit, a power supply module, a communication module, a carrier module and a security chip module which are arranged in the shell; according to the technical scheme, through the 230 MHz electric power wireless private network, a concentrator does not need to be adopted for forwarding, the built-in communication bin is directly connected with a service master station, intermediate links are reduced, the data acquisition efficiency is improved, and a network structure is flattened; an annular recognition technology of the carrier communication and a wireless private network is adopted, the carrier interference is reduced through one-way carrier communication, and the data recognition rate is increased; and moreover, after carrier communication is completed, the module enters a dormant state, energy consumption is reduced, and line loss is reduced.

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. The master station cannot 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
