Triple-authentication gate control system and control method

Abstract

The invention discloses a triple-authentication gate control system and a control method. The triple-authentication gate control system comprises an image collection module, a card reader module, a local controller module, a gate control output module, a mobile phone, a system management module and a database module. Through verifying whether an identity card is legal or not, the local controller module is triggered to be connected to Internet through 3G/GPRS, the system management module receives the login request of the local controller to generate random two-dimensional codes and time stamps which are sent into the mobile phone and the local controller module through multimedia messages and network, then, the local controller obtains two-dimensional codes through the card reader module, and compares the obtained two-dimensional codes to the two-dimensional codes downloaded from the system management module through 3G/GPRS network, next, the time stamp comparison is carried out, finally, whether all the authentication is legal or not is judged, and the gate is opened and images are collected if all the authentication is legal. The invention ensures high safety of the gate control system, has the advantages of short authentication time, high authentication accurate rate and low cost, and is favorable for large-range application and popularization.

Description

technical field [0001] The invention relates to an access control system and a control method, in particular to a triple authentication access control system and a control method for an unattended power distribution room. Background technique [0002] At present, the access control systems used to restrict the passage of unauthorized personnel generally use passwords, IC / ID cards, barcodes, biometrics and other technologies. With the development of science and technology, these single technologies are either easily cracked, or are not suitable for practical use in remote unattended power rooms. [0003] For example, with a single password, it is easy for others to see the password when entering the password; with IC / ID card technology, the IC / ID card itself is easy to be stolen or copied; with barcode technology, whether it is a paper barcode or other forms Barcodes are easily copied or copied; biometrics (whether fingerprints, palm prints, or irises) are used. On the one h...

With the development of technology, these single technologies are either easily cracked, or not suitable for practical use in remote unattended power rooms

[0003] For example, with a single password, it is easy for others to see the password when entering the password; with IC / ID card technology, the IC / ID card itself is easy to be stolen or copied; with barcode technology, whether it is a paper barcode or other forms Barcodes are easily copied or duplicated; biometrics (whether fingerprints, palm prints or irises) are used. On the one hand, these devices are very expensive and not suitable for use in this remote wilderness.

On the other hand, the recognition rate of these technologies is relatively low, and the construction personnel in the electric room or machine room have been dealing with cables, copper wires, iron wires or network cables for a long time, which is particularly easy to scratch fingers or palms and often stay up late, which will lead to fingerprint identification, The pass rate of palmprint recognition and iris recognition has become very low, resulting in the failure to open the access control

[0004] To sum up, the current access control system either has a single authentication method and is easy to be stolen or copied, or the technology is so advanced that the recognition rate is low and the equipment cost is very expensive, so it is not suitable for large-scale application in unattended electric rooms
