AI Technical Summary

Technical Problem

The existing technology lacks effective solutions to the access control management of distribution rooms in complex environments of power plants. Traditional password identification has information leakage and no inlet and exit records. Card identification is prone to loss. Fingerprint identification is high and is not reliable enough in complex environments.

Method used

An intelligent access control management system and method for power distribution room is adopted. By detecting the residence time of the object, if it exceeds the preset time, images will be collected, and face features are extracted using face detection algorithm and improved weight adjustment algorithm, and access control management is carried out based on these features.

Benefits of technology

It realizes access control management with low cost and high recognition accuracy in complex environments of power plants, and improves the operating efficiency of the power grid.

Abstract

The invention belongs to the technical field of intelligent access control, and discloses an intelligent access control management system and method for a distribution room, and the method comprises the steps: detecting the stay duration of an object when the object is detected to approach; if the staying duration exceeds a preset duration, acquiring an image of the object; performing face detection on the image by using a face detection algorithm; after a human face is detected, judging that the image is a human face image, and preprocessing the human face image; extracting face features from the preprocessed face image by using an improved weight adjustment algorithm; and performing access control management based on linkage of the face features and the door lock of the power distribution room, so that the access control management of the power distribution room is linked through face recognition, the cost is relatively low, the recognition accuracy is relatively high when a complex environment is dealt with, and the overall operation efficiency of a power grid is improved.
