Data acquisition device for building entrance guard management

Abstract

The invention relates to an information acquisition part of an entrance guard system, in particular to a data acquisition device for building entrance guard management. The data acquisition device forbuilding entrance guard management comprises a door main body and a rotary doorsill installed on the door main body and also comprises an image acquisition part, an acquisition driving mechanism andan arc-shaped sliding rail, wherein the arc-shaped sliding rail is installed on the inner side of the rotary doorsill, and the acquisition driving mechanism comprises a plurality of push rods peripherally fixed to a rotary shaft, an installing frame for installing the image acquisition part, a buffer spring installed in the arc-shaped sliding rail and arranged on one side of the installing frame and a reset spring installed in the arc-shaped sliding rail and arranged on the other side of the installing frame. When an entrance guard user pushes the rotary doorsill, the push rods push the installing frame to slide, the shape of the arc-shaped sliding rail makes the installing frame gradually away from the push rods and break away from the push rods in the pushed process, and the image acquisition part shoots radial images of the rotary shaft in the sliding process. The data acquisition device can acquire face data of more persons passing an entrance guard.

Description

technical field [0001] The invention relates to an information collection part of an access control system, in particular to a data collection device for building access control management. Background technique [0002] Entrance and exit access control safety management system is a new modern safety management system, which integrates microcomputer automatic identification technology and modern safety management measures. It involves many new technologies such as electronics, machinery, optics, computer technology, communication technology, and biotechnology. It is an effective measure to solve the security management of the entrance and exit of important departments. Applicable to various confidential departments, such as banks, hotels, computer rooms, armories, confidential rooms, offices, intelligent communities, factories, etc. [0003] The access control system that adopts facial recognition technology is arranged in the prior art. An important part of facial recognit...

AI Technical Summary

Problems solved by technology

The defect of the prior art is that a fixed camera is often used to take pictures of the user's head. The camera only captures a small amount of facial data from one angle and compares it with the stored user's facial data. The less facial data collected, The higher the likelihood of failure of facial recognition technology
