Two-dimensional code based access control system and door opening method

Abstract

The invention relates to a two-dimensional code based access control system and a door opening method. A scanned two-dimensional code containing door position encoding information and user information are sent to an access control management server through a special APP, and an unlocking instruction is sent to an access control controller corresponding to the door position encoding information after the access control management server checks the door opening permission information of a door position corresponding to a user. By the adoption of the two-dimensional code based access control system and the door opening method, the two-dimensional code containing door position encoding information and arranged nearby an access control is identified, the access control system can be simply, conveniently, quickly and comprehensively record in-out information of persons. A mobile terminal with a two-dimensional code which cannot be identified can be forbidden or alarmed, and the working amount of security personnel can be decreased while a community safety management effect can be effectively improved.

Description

technical field [0001] The invention relates to an access control system and a door opening method, in particular to an access control system and a door opening method based on a two-dimensional code. Background technique [0002] In modern residential quarters, office buildings and other buildings or buildings, the access control system sets a personal identification code for each user, and the user needs to rely on the personal identification code to pass through the access control system. Therefore, the access control system is to protect the life and security of users in the building. An important facility for property safety. [0003] With the rapid development of Industry 4.0 and intelligence, the Internet of Things technology is widely used in the integration of networks through communication perception technologies such as intelligent perception, identification technology and pervasive computing, and has become the third largest player in the development of the world...

AI Technical Summary

Problems solved by technology

In individual cases, user fingerprints are relatively shallow, and this verification mechanism cannot be used

Although the security of this access control system has been improved, the way of providing fingerprints multiple times reduces the user experience

Especially in public areas, the use of fingerprint access control is more difficult

Moreover, its cost is high, and the recognition rate is not high, and the slight wear and tear of human fingers will affect the recognition effect, so it is not suitable for mass promotion
