Problems solved by technology

The problem with this method is that since the memory in controller B is generally limited and has a small capacity
Therefore, this data storage method causes the number of users of the entire system to be greatly limited; if the number of users of the system is to be expanded, the storage capacity in each controller must be increased, which will increase the cost of the system
Therefore, as far as the current access control system is concerned, the larger the capacity of the system, the higher the price.

Embodiment Construction

[0016] Embodiments of the present invention will be described in detail below by constructing the above-mentioned accompanying drawings.

[0017] Such as figure 1 As shown, the present invention is similar to the traditional one in overall structure, and also includes a system host 1 , multiple controllers 2 , multiple card readers 3 and multiple electric locks 4 . The number of controllers 2, card readers 3 and electric locks 4 is equal to the number of controlled doors. That is, a controller 2, card reader 3 and electric lock 4 are all installed on each controlled door. The access control system also includes multiple user cards 10, and the number of user cards 10 can be set according to the number of users. In the above-mentioned system, the controller B stores the system number and the system password, and the user card 10 stores the system number, the system password, the card number and the authority data of the user. The content of the authority data is the same as t...

Abstract

An entrance guard system is composed of system host, multiple controllers connected to said system host, multiple card readers, multiple electric locks and multiple user cards. The system number and system password are stored in said controller. The system number, system password, serial card number and right data are stored on user card. It features that the number of users is independent with to memory capacity of controller.

Description

technical field [0001] The invention relates to an access control system, in particular to an access control system using a smart card. Background technique [0002] figure 1 A schematic structural diagram of a traditional identification system (also called an access control system) is shown. Such as figure 1 As shown, a general access control system includes a system host A, multiple controllers B, a reader C, an electric lock D, a door sensor E and an exit button F. The system host A is generally located in the host machine room and is used to control and operate the entire access control system. Each controlled door is equipped with a controller B. Therefore, the controller B is located at the controlled door and is connected to the system through a connecting line. Host A is connected to pass data and commands. Card reader C is installed outside each controlled door for reading data on user cards. If the user's card is valid, the controller B will send an instructio...
