Intelligent entrance guard control system

Abstract

The invention provides an intelligent entrance guard control system. The intelligent entrance guard control system comprises a control module, a fingerprint acquisition unit, an iris acquisition unit, an infrared illumination unit, an image processing unit, an image recognizing unit connected with the image processing unit, a memory module connected with a control module, an input module connected with the control module, a human body infrared sensor, an illuminance sensor, an entrance guard switch module, a communication module and a power supply module. For different positions of different security levels, fundamental recognizing modes of the intelligent entrance guard control system include a password recognizing mode, a recognizing mode combining passwords with fingerprints, an iris recognizing mode, a combined recognizing mode according to requirements and the like, so that the safety of the entrance guard is improved; the illuminance sensor is used for assisting the infrared illumination unit to work, so that the energy can be saved; besides, the built-in fingerprint matching and inputting functions of handheld mobile terminals including mobiles are utilized to control the opening and the closing of the entrance guard of which the security level is low, and during a time period with concentrated pedestrian flows, branching is performed relying on a long-distance technology, so that the recognizing efficiency is accelerated.

Description

technical field [0001] The invention relates to the field of biological feature identification, in particular to an intelligent access control system. Background technique [0002] Biometric identification technology refers to a technology that uses human characteristics for identity authentication. Among all biometric features, fingerprints are relatively stable and easy to collect and identify. Iris is a biometric feature in the body and will not be affected by wear and aging. Among various biometric identification methods, iris identification has the lowest error rate. [0003] With the rapid development of electronic information technology, traditional locks continue to develop in the direction of high technology and intelligence. There are more and more applications of intelligent control locks, such as door locks with card swiping functions. Electric control access control locks are a kind of The chip's card contacts the lock sensor to open the door lock, replacing so...

Problems solved by technology

[0004] Existing technology: a fingerprint and iris fusion recognition device, patent application number: 201310583519.2, adopts the following scheme: a fingerprint and iris fusion recognition device, mainly composed of a microcontroller, an infrared distance measuring unit, an iris collection unit, and a fingerprint collection unit , light feedback unit, infrared lighting unit, living body detection unit, image preprocessing unit, image recognition unit and an optical system to prevent the user's head from rotating; among them, the feature matrix of fingerprint and iris is used for fusion recognition instead of separate recognition ;Aiming at live detection, a method that is easier to use and reliable without algorithm dependence is proposed, which can quickly perform live detection; for iris recognition, a solution to prevent head rotation is proposed; for the influence of natural light, a A method for removing natural light; although the method for fused recognition of fingerprints and irises provided by the present invention is more reliable than the independent application of the two, it will be time-consuming and efficient when used in some places where the level of confidentiality is not very high. Low, its infrared lighting unit cannot be turned on in real time according to the external lighting conditions, it is not smart enough, and it cannot be combined with a handheld mobile device, and it relies on remote technology to divert traffic during the time period when the flow of people is concentrated.
