Abstract

The invention relates to a power distribution room integrated access control system based on a time synchronization dynamic password and a using method thereof. The dynamic password authentication technology based on time synchronization is applied to a power distribution room access control system, which effectively solves the defects of locks and keys of the traditional power distribution room.The problem of reproducibility of the physical key is effectively solved, the power distribution room can be accessed safely and efficiently when the staff does not carry the key, and the forensic problem after the power distribution room is stolen is solved.

Description

technical field [0001] The invention belongs to the field of electric power information systems, and relates to a comprehensive access control system for a power distribution room, in particular to a comprehensive access control system for a power distribution room based on a time-synchronized dynamic password and a method for using it. Background technique [0002] At present, the power distribution room of the power system is unattended, and most of its door locks still use mechanical locks or magnetic locks. The keys of mechanical locks and magnetic locks are entities, and entity keys have obvious defects. First, once the physical key is lost or stolen, the power equipment in the power distribution room will face the risk of being stolen, which will also endanger the safety of the power grid operation; Inconvenience. [0003] The dynamic password is an unpredictable combination of random numbers generated according to a specific algorithm, and each password can only be ...
