Intelligent access control system based on sensor network

Abstract

The invention provides an intelligent access control system based on a sensor network. The intelligent access control system based on the sensor network comprises a central processing device, a temperature sensor, a signal processing circuit, a fingerprint acquisition module, a camera, a first trigger module, a temperature identification module, a fingerprint identification module, a second trigger module, n image recognition module, a third trigger module, a gate control module, a non-gate circuit and an alarm module, wherein the temperature sensor is used to confirm the human body entering the access control, and the signal processing circuit is used to improve the temperature monitoring accuracy; when detecting that there is a human body, the fingerprint collection module is triggered to perform fingerprint collection operations; when the collected fingerprint is the fingerprint of the person who is allowed to enter the access control, the camera is further triggered to perform image collection, and then the image recognition module extracts the feature information of the image for further judging whether the person who enters the access control is allowed to enter the access control.

Description

technical field [0001] The invention relates to the field of intelligent electromechanical devices, in particular to an intelligent access control system based on a sensor network. Background technique [0002] The level of science and technology in today's society is developing rapidly, and information technology is the leader in the level of scientific and technological development. Various scientific and technological levels based on information technology are undergoing rapid changes. People are always feeling the convenience brought to life by the rapid development of scientific level, and at the same time, they have put forward demands for the development direction of science and technology. Although the development of science and technology has brought convenience to people's lives, it has also brought new security risks, and crimes using high technology are gradually increasing. The traditional door lock system is far from meeting the needs of today's society, so th...

Problems solved by technology

[0005] In the prior art, the intelligence of the access control system is getting higher and higher, but its work efficiency is low. For example, if the access control system uses fingerprint recognition, it is easy to be used by others. If image recognition is used, when the images are matched, At present, the accuracy of image recognition is low or the response speed is slow. If a temperature monitoring device is used to determine the person entering the access control, the accuracy of temperature collection is low, and it is easy to cause misjudgment of intelligent access control.
