An access control system that realizes unlocking with a cipher device without a cipher disk and its application method

Abstract

The invention discloses an access control system capable of achieving cipher device unlocking without using a cipher disk. The access control system comprises a controller, a radio frequency card and a card reading induction coil installation base; a through hole is formed in the right end of the radio frequency card, an installation groove is formed in the left end of the radio frequency card, a radio frequency card induction coil is installed in the installation groove, a radio frequency card chip and a magnet are installed on the center position of the radio frequency card induction coil, an ID storage module is arranged inside the radio frequency card chip, and a radio frequency card cover matched with the installation groove is installed at the upper end of the radio frequency card chip; the system can be completely put in a wall, no equipment needs to be installed outside the door, therefore, violent disassembling can be effectively prevented, all radio frequency cards pass through the ID storage module which is internally provided with an ID with uniqueness, the controller can be used for conducting authorization and permission distribution management on the radio frequency cards according to a certain program, and therefore the integral safety of the access control system is greatly improved.

Description

technical field [0001] The invention relates to the technical field of design of access control systems, in particular to an access control system and a method for using the access control system which does not use a password disk to unlock a cipher device. Background technique [0002] At present, all the access control systems on the market need to be equipped with a password disk to open the door with a password. Since the installation of the password disk will increase additional construction costs, and professionals can illegally crack the access control system through the password disk, the access control system with a password disk is safe. The security is low, and some access control systems that use radio frequency cards to unlock do not lock the ID of the radio frequency card, so that criminals can use illegal cards to intrude, and the radio frequency card does not carry out sub-authority management, so that ordinary radio frequency cards also have improved The abi...

[0002] At present, all the access control systems on the market need to be equipped with a password disk to open the door with a password. Since the installation of the password disk will increase additional construction costs, and professionals can illegally crack the access control system through the password disk, the access control system with a password disk is safe. The security is low, and some access control systems that use radio frequency cards to unlock do not lock the ID of the radio frequency card, so that criminals can use illegal cards to intrude, and the radio frequency card does not carry out sub-authority management, so that ordinary radio frequency cards also have improved The ability to open the door with an illegal card also reduces the security of the access control system. At the same time, because the existing access control system works in the way that the controller keeps scanning whether there is a radio frequency card approaching, it still needs to consume a lot of energy when there is no radio frequency card approaching. energy of
