Distribution transformer monitoring terminal supporting double-master-station redundant communication and data processing method

Abstract

The invention provides a distribution transformer monitoring terminal supporting double-master-station redundant communication and a data processing method. The terminal comprises a shell, and a serial interface, an input / output interface, a first Ethernet interface, a second Ethernet interface, a remote signaling remote control module, an electric quantity acquisition module, a power supply module, a main control data processing module, a first wireless communication assembly and a second wireless communication assembly connected to the shell. The first wireless communication assembly and thefirst Ethernet interface are used for accessing a first network, and the second wireless communication assembly and the second Ethernet interface are used for accessing a second network. According tothe distribution transformer monitoring terminal supporting double-master-station redundant communication and the data processing method, a redundant communication unit, such as a double-network communication assembly, is added to the distribution transformer monitoring terminal equipment, and data is reported to a main station and a standby main station at the same time during data reporting, sothat the communication data volume between the main station and the standby main station is reduced, the data communication bandwidth is reduced, the redundant communication efficiency is improved, and the redundant cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electric power distribution, in particular to a distribution transformer monitoring terminal and a data processing method supporting redundant communication of dual master stations. Background technique [0002] At present, in the power distribution process of the power grid, there are a large number of electrical information data collection, data communication, big data calculation, control output, and storage and backup of historical data, etc. In terms of data security, these data need to have redundant backup and remote disaster recovery requirements. However, in the current solution, redundant backup and remote disaster recovery are realized through data redundancy communication between the master station and the backup master station. Since each master station can be connected to many distribution transformer acquisition terminal devices, the amount of data received by the master station and that n...

AI Technical Summary

Problems solved by technology

High bandwidth means high cost, especially in the application environment of remote disaster recovery, the redundancy cost will be higher

[0003] The existing distribution transformer monitoring terminal equipment has a high degree of integration, and the amount of electrical information data that can be collected and processed is large, but it communicates with a single master station, and the data redundancy backup and data The pressure of transmission is placed between the master station and the backup master station, resulting in a large amount of data transmission in the redundant communication channel between the master and backup stations, high bandwidth requirements, high redundancy costs, and low data communication efficiency for remote disaster recovery
