Micro relay protection automatic measurement and control device with electronic identity recognition function

Abstract

The invention discloses a micro relay protection automatic measurement and control device with an electronic identity recognition function. The micro relay protection automatic measurement and control device comprises a measurement and control unit, a human-machine interface unit and an electronic identity recognition unit, wherein the measurement and control unit is provided with an independent central processing unit (CPU) control, and has a data acquisition processing function and a logic judgment execution function; the human-machine interface unit comprises an operating system and a display system; and the electronic identity recognition unit comprises an electronic identity acquisition system and an identification analysis system. The electronic identity identification unit is used for analyzing and conforming the legality of operation, refusing illegal operation, permitting operation within an authorization range, recording the ID, the operation time and the operation content of an operator, and guaranteeing the controllability and the traceability of key equipment and key operation, so that the micro relay protection automatic measurement and control device has functions of authorizing, inspecting and automatically recording.

Description

[0001] Field: [0002] The invention relates to a power distribution microcomputer protection device, in particular to a miniature intelligent relay protection automatic measurement and control device with electronic identity recognition function applied in a power distribution substation micro relay protection automatic measurement and control device. Background technique: [0003] The microcomputer relay protection automatic measurement and control device is the necessary equipment for data acquisition, local remote control and fault protection of distribution substations. The existing micro-relay protection automatic measurement and control device has a human-machine interface unit for operation and monitoring. In terms of operation authorization, Use the short password to authorize. The short password is provided to all operators. In fact, the security function of the password has been lost, and the management personnel cannot know who is operating and what content is being...

[0003] The microcomputer relay protection automatic measurement and control device is the necessary equipment for data acquisition, local remote control and fault protection of distribution substations. The existing micro-relay protection automatic measurement and control device has a human-machine interface unit for operation and monitoring. In terms of operation authorization, Use the short password to authorize. The short password is provided to all operators. In fact, the security function of the password has been lost, and the management personnel cannot know who is operating and what content is being operated. It is easy to cause the relay protection parameters to be artificially manipulated. The hidden danger of malicious modification, resulting in failure of device protection
