Entrance guard system and entrance guard opening method

Abstract

The invention provides an entrance guard system and an entrance guard opening method. The entrance guard system includes: a mobile terminal, which is used for emitting a signal for opening an entrance guard device; a control device, which is respectively connected with the mobile terminal and the entrance guard device through wireless communication connection signals of Wi-Fi, after receiving a signal of opening the entrance guard device, judging whether the signal of opening the entrance guard device matches with set information, and when the signal of opening the entrance guard device matches with the set information, controlling opening of the entrance guard device. The entrance guard system and an entrance guard opening method provided by the invention utilize the mobile terminal as the voucher and have no need for additional induction card, and pay more attention to maintenance of personal articles, which cannot be easily lost. The Wi-Fi wireless communication function of the mobile terminal is utilized, the control device adopts an AP mode to establish WLAN hot spots, the influence of SIM cards does not exist, mobile phone outage and other circumstances are unnecessary to consider, and the extra communication fee problem cannot be generated. An independent extensible network module has no need of external network constraints and supports offline operation.

Description

technical field [0001] 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 [0002] 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: [0003] 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 s...

AI Technical Summary

Problems solved by technology

[0003] 1. Combination lock scheme, which mainly installs electronic locks at the entrance, and enters the password to verify the access control authority, but the password is easy to cause theft, deciphering, etc., and the security is poor

[0004] 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 Theft requires users to carry it with them, and the loss is more serious

[0005] 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. Duplication, speech recognition has weak anti-interference ability, low recognition rate, complex face recognition algorithm, expensive sensors, and high cost

[0006] 4. The SMS phone method mainly realizes the verification of access control authority by sending special information to the designated number or making a phone 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.

[0022] 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
