Embedded access control system and operation method thereof

Abstract

The invention discloses an embedded access control system and an operation method thereof. The system comprises an electromagnetic door lock and a relay connected with the electromagnetic door lock, and also includes: a camera which is used for acquiring a face image and a real-time scene of a monitoring area and generating face recognition data and monitoring scene data; an information input module which is used for inputting pre-stored information and inputting an unlocking key; an infrared detector which is used for detecting biological temperature characteristics of the detection area andgenerating biological characteristic data; a server which is used for receiving and storing the face recognition data, the monitoring scene data, the pre-stored information, the input unlocking secretkey and the biological temperature characteristic data, wherein the server is further electrically connected with the relay and outputs a high-level or low-level electric signal to the relay, and theelectromagnetic door lock is controlled by the relay to be opened and closed; and an audio output module which is connected with the server and controlled by the server to output audio information, and the scheme is reliable in implementation, good in efficiency and good in safety.

Description

technical field [0001] The invention relates to the technical field of access control, in particular to an embedded access control system and an operating method thereof. Background technique [0002] In today's increasingly informationized society, the application of computers and networks has fully penetrated into daily life. The application of embedded systems can be seen everywhere, such as: aerospace, automotive, medical, industrial control, etc. have large-scale applications of embedded systems. [0003] In recent years, with the promotion of smart life and smart home concepts, embedded systems are getting closer to people's lives, replacing traditional products and becoming an important part of smart life. The rapid development of intelligent access control system is typical of them. Compared with traditional door locks, functions such as fingerprint recognition, face recognition, and voice recognition are added to replace traditional keys and passwords, and biometr...

AI Technical Summary

Problems solved by technology

[0005] 1. The speed and efficiency of face recognition are low

Due to the limitation of cost control and development cycle, the hardware of face recognition is relatively backward. Although it can meet the recognition requirements, the speed is not fast, and the addition of neural network is lacking.

Moreover, the recognition algorithm is relatively backward, and it is often necessary to recognize multiple times

[0006] 2. The access control system is closed and does not form interconnection with other devices through the network, thus missing functions such as remote reminder, control, and information viewing

[0007] 3. Low security level

① The level of cracking is low, and the existing equipment lacks protection against technical cracking

For example, high-frequency pulses generated by Tesla coils can easily cause the system to crash and restart. After restarting, the system generally opens the door lock by default, resulting in cracking.

② Potential security level is low, the system will not store the face data of strangers who try to unlock, so as to remind the owner to prevent potential danger

[0008] 4. Functional redundancy

[0009] 5. High cost
