An intelligent lock system with a dynamic two-dimensional code

Abstract

The invention provides an intelligent lock system with a dynamic two-dimensional code. The intelligent lock system is provided with an intelligent lock control device, a dynamic two-dimensional code generation device, a face recognition device and an alarm device. The intelligent lock device It includes a deadbolt drive circuit that drives the deadbolt to unlock or lock, the face recognition device includes a hidden camera installed on the door leaf, a main control device connected to the camera, the main control device includes a central processing unit, and A memory connected to the central processing unit, a communication module and a camera drive circuit, the memory is equipped with a face recognition analysis system, the bolt drive circuit and the alarm device are respectively connected to the main control device; one of the face recognition analysis systems The system has a face shape, and the access control QR code in this design is generated locally, which ensures the continuity and safety of the system as a whole.

Description

technical field [0001] The invention relates to the field of access control based on biometric identification, in particular to an intelligent lock system with a dynamic two-dimensional code. Background technique [0002] QR code scanning to open the door Face recognition access control is a new type of access control application technology that has emerged following the development of computer network technology and artificial intelligence technology. Due to its convenience and non-contact advantages, it has gradually been promoted and used in the access control industry. At present, due to the great difference in the installation environment of the commonly used face recognition access control, for example, supplementary light needs to be considered in the case of poor light, and technologies such as wide dynamic range should be considered in the strong light environment, which leads to the need to configure the face independently in some application scenarios.

Problems solved by technology

However, the problem brought about by such modification is that it cannot be connected to the power supply or the life of the cable cannot be guaranteed after repeated opening and closing of the door, so the modified smart door locks are mostly powered by batteries

In this case, once the battery power is low or malfunctions, the door lock will appear unable to open

[0006] As a safety barrier, the door lock is one of the important devices to protect the property in the home from being stolen. However, as a protective device, the door lock is often used to protect the gentleman and not the villain. It does not really play a protective role and cannot be timely Alarm and transmit information; As the safety of home portals has attracted more and more attention, anti-theft doors are widely used in life

At present, there are mainly two types of anti-theft doors on the market. One is the ordinary anti-theft door that relies on mechanical locks. Doesn't work as a deterrent and deterrent

The second is an intelligent anti-theft door with a camera module. The existing intelligent anti-theft door is basically equipped with a camera module. The image information outside the door is recorded through the camera module, and the image information is stored locally, which can deter criminals to a certain extent. function, but the function is very single, and it cannot effectively connect the smart module to the mobile terminal remotely. When the owner is not at home, it is impossible to check the situation outside the door in real time

[0008] The existing intelligent anti-theft door locks cannot be connected with the external security control platform, nor can the location information be effectively fed back to the security control platform. notify each family
