Embodiment Construction

[0013] Such as figure 1 As shown, a specific embodiment of the armature clamp according to the present invention is given. In the figure, the limit switch 1 is installed in linkage at 5 places of the electric door lock. The limit switch 1 is connected to the control terminal 2 by communication. The access control The device 4 is an IC card integrated recognition controller, and adopts Philips Mifare series non-contact read-write chip, and adopts a 32-bit embedded processor with a Cortex-M3 core with low power consumption and strong computing power; in order to realize the access control card number and The storage of card reading records adopts ATMEL large-capacity FALSH memory, which provides storage space for 500 records and has the function of power-off retention, which greatly improves the flexibility of using cards and facilitates on-site proofreading and identification and post-management ; The control terminal 2 is a remote control terminal, which uses encryption protoc...

Abstract

An access controller comprises an electric door lock, an access controller, and a control terminal. A limit switch is arranged on and in a linkage relation with the electric door lock, and the limit switch communicates with the control terminal; the access controller is an IC card one-piece identification controller adopting a contactless read-write chip; the control terminal is a remote control terminal adopting an anti-interference communication chip and communicates with a grandmaster center and a plurality of systems of the access controller through encryption protocols. The access controller employs a 32-bit flush bonding processor with a Cortex-M3 core, and a PCB moistureproof plate housing coated with ultraviolet-resistance coating. The access controller of the invention has higher safety performance, a long service life and reliability for usage under severe field conditions.

Description

technical field [0001] The invention relates to an access control system, in particular to an access control system. Background technique [0002] The traditional mechanical door lock is just a simple mechanical device. This kind of door lock is easily damaged by external force. Therefore, although various improvements have been made, the safety performance is moderate and difficult to break through, and it needs to be specially equipped with a key that matches the lock. The key is lost or replaced by personnel. To replace the lock and the key together increases the cost and causes a waste of resources. With the advancement of science and technology, locks with high technological content such as electronic magnetic card locks and electronic combination locks have appeared. These two electronic locks also have many shortcomings. The information of the magnetic card lock is easy to copy, the wear between the card and the card reader is large, the failure rate is high, and the...
