Power distribution terminal safety access system based on electric power internet of things

Abstract

The invention discloses a power distribution terminal safety access system based on an electric power internet of things. The power distribution terminal safety access system comprises a power distribution terminal, a safety access device and a safety access gateway, the system is characterized in that an identification module is further arranged between the power distribution terminal and the safety access device, and the identification module comprises a front-end verification module, a gating unit, an auxiliary processor and a database; through the power distribution terminal, the safety access device and the identification module arranged between the power distribution terminal and the safety access device, the access habit of the power distribution terminal can be monitored, and whenthe access habit of the power distribution terminal is not met, the identity of the power distribution terminal needs to be verified; according to the verification method, unique identification codesare generated respectively, and the generation mode can only be uploaded in a local mode; the key data can only be changed in a local mode, so that embezzlement is avoided; through the verification mode, the problems can be solved; and meanwhile, the access meeting the habits of the user is allowed to pass.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things security, in particular to a power distribution terminal security access system based on the Internet of Things. Background technique [0002] The patent with the publication number CN208939584U discloses a new type of smart distribution network terminal security access system, which avoids replacing the existing CPU board with a CPU board running a commercial secret algorithm or directly replacing the terminal. The existing power distribution terminal is upgraded and transformed by adding a safety access device alone, which makes the transformation process simpler, lower the transformation cost, and has a wider scope of application. The utility model comprises a power distribution terminal and a security access gateway; a security access device for connecting the power distribution terminal and the security access gateway; the security access device comprises a casing, and an ARM proce...

Problems solved by technology

[0003] However, for this patent, it does not analyze the access status of the power distribution terminal, and does not know whether the connected power distribution terminal is a real terminal, or it is falsely connected to the network; therefore, it lacks a certain A system that can be intelligently identified based on the access habits of power distribution terminals; in order to solve this technical defect, a technical solution is now provided
