Communication protection system of electric power internet of things

Abstract

The invention discloses a communication protection system of an electric power internet of things. The system comprises an agent module, a branch central server and a central server, the proxy module is in communication connection with the branch center server and the central server and is used for accessing the Internet of Things equipment and the branch center server in a proxy mode; the branch center server is in communication connection with the agent module and is used for performing access control on the Internet of Things equipment to join the Internet of Things; and the central server is in communication connection with the agent module and is used for performing centralized management on the Internet of Things equipment and the branch central server accessed by the whole Internet of Things. The method can be applied to a power internet of things scene with massive and diversified equipment access, and equipment access admission and encrypted communication based on the password technology are realized.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a safety protection system of the Internet of Things for electric power. Background technique [0002] In the field of power industry, a large number of intelligent sensing devices are widely used in power generation, power transmission, power transformation, power distribution, power consumption and other fields, especially the power grid management units at all levels must face the secondary system of power plants, long-distance power transmission systems, The accuracy of the work information reporting of all relevant equipment in the substation system, distribution network at all levels and the final power consumption system. In such an environment, the interruption or counterfeiting of communication in any link will trigger the maintenance procedures of the entire power system and power grid. If the conventional maintenance methods cannot solve the fault for a ...

Problems solved by technology

In such an environment, the interruption or counterfeiting of communication in any link will trigger the maintenance procedures of the entire power system and power grid. If the conventional maintenance methods cannot solve the fault for a long time, it may lead to power outage and maintenance in a certain area Waiting for loss

[0003]Currently, the security protection of the existing industrial control IoT mainly relies on physical isolation, or private network isolation provided by operators to achieve protection against external attacks. to self-managing, self-encrypting, and natively secure
