Swipe card lock principle illustration Swipe card lock principle of work flow introduction

The swipe door lock is an electronic lock that is sensed through an infrared sensor. The smart card fields such as hotels, guesthouses, and clubs have been widely used, and are mainly divided into radio frequency door locks and induction locks. The IC card is currently the mainstream. Q5d smart lock China

The card lock sensor has a built-in coil, and the power is oscillating. Similar to the primary coil of the transformer, the door card also has a built-in coil, which is equivalent to the secondary coil of the transformer. When the two coils are close to each other, a current is generated by the coupling to realize the card power supply. The coupling sends an inquiry signal, the door card answers, and the door can be opened if the conditions are met. Q5d smart lock China

The IC card door lock system basically consists of five parts: a central management computer, an IC access control card, a card reader, a door lock, and a controller. Q5d smart lock China

The role of the management computer is to manage and write IC card operations, according to different types of users can create room cards with different functions and permissions (such as regular guest card and administrator card), and can manage the hotel's access control system, query Unlock records and other operations.

The IC card basically includes user memory, protection memory, and encryption memory. The role of user memory is to store the basic information and unlock records of the hotel code, identification code, control code and other locks. Programmable passwords and error counters can be stored in the encryption memory. The change of data in the user memory can only be performed after entering a secure programmable password. The IC reader can write the information in the read card under the control of the front desk computer. The front desk is external and used for issuing cards. The lock is built-in, reads the card's function permission information. Q5d smart lock China

The door lock itself consists of an electrical control structure and a mechanical execution structure. The right-hand single-chip microcomputer control system control of the electric control mechanism can be programmed through a function card or a controller. When working, read the information in the inserted IC card and perform processing comparison to control the door lock. For example, by checking, the micro-motor in the lock cylinder is controlled to perform an unlock operation and the like. Q5d smart lock China

The mechanical part of the card door lock consists of a lock cylinder, an outer lock body and an inner lock body. The lock cylinder includes a lock tongue and a safety tongue and a complete mechanical structure in which the micromotor is embedded. The external lock body includes a handle, a clutch mechanism, an IC reader/writer, an electrical control board, and an indicator light. The controller is mainly used for communication between the door lock and the front desk computer, writing computer information or extracting information inside the lock. Q5d smart lock China

Because the magnetic card door lock is gradually eliminated due to being easily copied and copied, and the IC card has stored information and realized encryption, the security level is higher and has been widely used. Q5d smart lock China

The above is the working principle of smart lock China network Xiaobian finishing the release of the credit card door lock, more knowledge principles of the lock, please pay attention to this section related science popularization! Q5d smart lock China
