Description

Access control system and method for opening access control

technical field

The invention relates to the technical field of access control, in particular to an access control system and an access control opening method.

Background technique

With the development of society, people have higher and higher requirements for personal and property safety. The traditional key opening method is easy to be copied, often forgotten or lost, and the identity of the person who opened the door cannot be verified, causing great safety hazards and cannot meet the current needs. The needs of space protection such as university laboratories, office spaces, and smart homes require a more advanced access control system. At present, common access control system identification methods include the following:

1. Combination lock scheme. This scheme mainly installs an electronic lock at the entrance, and enters the password to verify the access control authority. However, the password is easy to cause theft and deciphering, and the security is poor.

2. Radio frequency identification technology. This method requires supporting transponders, such as magnetic cards and IC cards (Integrated Circuit Cards). Access control rights are confirmed by reading the information on the radio frequency tags in the cards. However, at present, proximity cards are not only easy to be forged and Misappropriation requires the user to carry it with him, and the loss is more serious.

3. Biometric identification technology, which mainly uses sensors to obtain fingerprints, voice and face features to verify the uniqueness of biological individuals, thereby judging access control permissions. However, special sensors are required for identification, and fingerprint identification is contact type, which is unhygienic and easy to be stolen. Replication, speech recognition has weak anti-interference ability, low recognition rate, complex face recognition algorithm, expensive sensor, and high cost.

4. The SMS phone method mainly realizes the verification of access control authority by sending special information to the designated number or making a call. This method has a certain delay and needs to consider the issue of communication charges. In the long run, it is not an economical and practical method. .

The above access control systems have their own limitations, especially in university laboratories, office spaces, and smart homes. Therefore, a more reasonable solution is needed to solve this contradiction.

Technical solution of prior art one

Combination lock solution, this solution mainly installs an electronic lock at the entrance, fixes the combination keypad outside the door, and verifies the access control authority by entering the password.

.Using the password lock scheme, because the personnel who have access to the password is more complex, there is a great security risk, the password is likely to be leaked during the input process, the password is easy to cause theft, deciphering, etc., and the security is poor.

Technical scheme of prior art 2

Radio frequency identification technology, this method requires supporting transponders, such as magnetic cards and IC cards, to confirm the access control authority by reading the radio frequency tag information in the card, and when the access control system reads the information in the card, it will pass the information in the card to the access control The controller, after the controller verifies the authority, controls to open the door lock.

The shortcoming of prior art two

The disadvantage of radio frequency identification technology is that the proximity card is not only easy to be forged and stolen, but also needs to be carried by the user, and the loss is serious, which is not only inconvenient but also causes a waste of resources.

Technical scheme of prior art three

Biometric identification technology mainly uses sensors to obtain fingerprints, voice and face features to verify the uniqueness of biological individuals, thereby judging the access control authority and realizing the door opening function. The fingerprint identification access control system mainly receives fingerprint data through the fingerprint collector, processes the fingerprint data through the data processor, and matches with the fingerprint in the database to control the access control device; voice recognition generates a group of characters or numbers randomly, and the user reads according to the prompts , the voice acquisition module obtains the voice signal, the main processing module processes the collected voice data, converts the analog signal into a digital signal, and then compares it with an algorithm to realize the control of the door lock; the face feature recognition is captured by a CMOS infrared camera group The black-and-white grayscale face image is filtered and then transmitted to the main processor for processing. The face feature data is extracted through the face recognition algorithm, and the access control and attendance functions are realized through comparison in the face database.

Shortcomings of prior art three

Feature feature recognition technology requires the use of special sensors. Among them, fingerprint recognition is a contact type, which has hidden health hazards and inconvenience, and is easy to be copied out of fingerprint printing film; voice recognition has weak anti-interference ability and low recognition rate; face recognition The algorithm is complicated, the sensor is expensive, and the cost is high.

Technical scheme of prior art 4

Short message phone mode, including mobile phone terminals for sending short messages or making calls and gate control terminals for receiving short messages or calls, by installing a SIM card and a short message receiving module in the gate control terminal to receive control instructions from the mobile phone terminal, And by analyzing and processing the instruction, verifying the access control authority, and realizing the function of controlling unlocking.

Shortcomings of prior art four

In the way of SMS phone calls, since the reliability and stability of the GSM (Global System for Mobile communication, Global System for Mobile Communications) network cannot be fully guaranteed, there is a certain delay in transmitting data, and the problem of communication charges needs to be considered. In the long run Not an economical and practical way.
