Abstract

The invention discloses a method and device for managing communication security of an intelligent electric meter. The method comprises steps that messages sent by other modules and external equipmentare received, the other modules are a metering module and an extension module in the intelligent electric meter, and the intelligent electric meter comprises a metering module, a management module andan extension module; the link layer format of the message is checked so as to determine a qualified message with a qualified format, legality of the qualified message is verified, and the qualified message passing the legality verification is determined as a legal message; and communication data interaction of legal messages is realized by utilizing a software security management application program in a manner of calling the embedded security control module.

Description

technical field [0001] The present application relates to the technical field of power systems, in particular to a method and device for managing communication security of smart meters. Background technique [0002] The power Internet of Things is the innovative integration and development direction of the new generation of energy systems and Internet technologies. It is a higher stage of the development of the smart grid. features. At present, my country's electric meters use dedicated electric energy meter integrated circuits to complete the data collection of electric energy, and the function scalability is low. Under the background of promoting the construction of the electric power Internet of Things, the new generation of modular smart electric meters integrates electric meter business by building a trusted operating system. App-based, the electric meter is used as the end-sensing terminal of the ubiquitous power Internet of Things, and it becomes the entry point for v...
