Embodiment Construction

[0046] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0047] In the following description, it should be understood that, unless otherwise specified, the card number referred to refers to a specific symbol or number to replace the person to be in and out, including number or code. Card swiping means that the access control system can identify the electronic information of the person to be in and out, including sensing devices such as swiping access control cards, work cards or other electronic devices.

[0048] The following embodiments can be applied to nuclear facilities, and can also be applied to other places with strict access control, such as places with high security protection requirements such as prisons and banks.

[0049] Such as figure 1 As shown, for the purpose of the i...

Abstract

The invention provides an access control method and system with a global anti-back-transmission function, comprising the following steps of: pre-storing an authorized card number, latest position information of the card number and a route map of the whole area in a controller; after receiving a legal door opening request and card swiping position information of a local logic rule, comparing the received position information of the card number with the stored latest position information of the card number to judge the overall anti-return transmission legality of the door opening request, and controlling a corresponding door to be opened after judging legality; and updating the latest position of the card number stored in the controller to be the target position to which the door opening request goes according to the route map of the whole area. By adopting the method and the system, whether the card swiping personnel violate the anti-back-transmission behavior rules can be directly judged by using hardware, the adverse effect of the software of the upper computer is eliminated, the unsafe factors such as the card swiping of the passers across defense areas, the card swiping and thecard access of multiple persons by using the same card and the like are effectively solved, and the facility safety is improved.

Description

technical field [0001] The invention belongs to the field of security technology, and in particular relates to an access control method with a global anti-passback function, and an access control system with a global anti-passback function. Background technique [0002] Nuclear facilities are important safety places, and their access control system is an important guarantee for ensuring the safety of nuclear facilities. With the development of information technology and threat situations, higher requirements are put forward for the security and reliability of the access control system. Anti-passback is a high-security and high-reliability access control mechanism that emerged during the development process. [0003] Anti-passback refers to the measures to control the situation that the cardholder cannot swipe the card across the defense zone, the entry and exit process is not closed-loop, and multiple people cannot use the same card to swipe the card to enter and exit. At p...
