What are the non-contact IC card door lock specifications? What are the technical characteristics of non-contact electronic inductive door locks? The non-contact type IC card door lock is a kind of electronic induction door lock. It uses the IC card as the unlocking medium and has the characteristics of non-contact induction unlocking. Integrated IC card encryption technology, mechatronics technology, and computer technology are suitable for use in communities, hotels, hotel apartments, etc. Unlike contact IC card door locks, non-contact IC card door locks can be located near the sensing area (before contact ) Complete identification.
The IC card is a new type of smart card identification (including proximity cards, IC cards, TM cards, etc.) and mainly uses silicon chips to store information. Therefore, it has a larger storage capacity than traditional identification cards (magnetic cards, barcode cards, and photovoltaic cards). It is widely used in communications, finance, transportation, security and many other fields.
The control mode of the key card: According to the hotel management needs, the key card of the IC card hotel computer door lock adopts the following control mode.
Password Control: All the keys of the key card are set by the hotel, and then the system uses the encryption algorithm to ensure the safety of the hotel. After different systems and systems have been coded, the key card password must be changed accordingly. The key card that has not changed the password cannot be unlocked.
Time control: The key card can only be unlocked within its effective time. It cannot be unlocked when it expires or is not in working time.
Regional control: The key card can only be unlocked within its effective area, and can only be unlocked in other areas, and is invalid for locks in other areas.
Level control: different levels of key cards can open the door lock range is not the same, the highest level can open all locks, the lowest level can only open a designated single lock.
Report loss function: You can report the loss of any card in the system without affecting the normal use of other cards.
File records: Each time you unlock (including mechanical key unlock), the door lock must record the unlock mode, card number and time for reference.
The type of card: According to whether the door can be classified, the smart card of the system can be divided into two categories: management card and opening card.
The front office management computer is responsible for writing IC card operations, creating cards with different functions and permissions according to different user types (such as guest cards and management cards, which can open many doors), and managing the hotel's access control system. Statistics unlock record.
The IC card generally includes a user memory, a protection memory, and an encryption memory. The user memory stores key information such as hotel codes, identification codes, control codes, and unlock records. Stored in the encryption memory programmable passwords and error counters. 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.
The door lock itself consists of an electrical control mechanism and a mechanical actuator. The electrical control mechanism is a single-chip microcomputer system that can be programmed at any time by a function card or controller. During normal operation, the information in the inserted IC card is read and recognized, and the door lock is controlled. If verified, the micro-motor in the lock cylinder is controlled to perform the unlock operation. The mechanical part 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 series of mechanical structures 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 indicator lights.
The controller is mainly used for the communication between the door lock and the front computer, writes the computer information or extracts the information in the lock.
Magnetic card door locks are relatively easy to be copied and stolen, and IC cards can be encrypted and difficult to be copied, so IC card locks are currently popular in hotels and other places.
IC card door lock (system) is mainly composed of five parts: front desk management computer, IC card, IC card reader, door lock, controller.
Cylinder: Five lock tongues (combination inclined tongue, insurance tongue, square tongue) intelligent lock core with lock tongue detection micro switch and micro motor, and can be unlocked in two independent ways to realize electromechanical double control.
Actuator: imported micro-motor, large travel, high power bolt, and can be locked in the predetermined position.
There are two kinds of lock shells: combination lock shell: the outer layer is a high-quality thin sheet, and the inner layer is a high-strength thick sheet.
Integrated lock shell: high quality die-cast alloy.
Unloading the battery: Unload the battery from the side, easy to conceal, and will not cause the loosened and displaced lock body;
Prevent alkaline battery leakage from corroding the lock cylinder.
Back-up mechanical key lock: Use seven-ball lock or computer key lock.
Handle support: The use of extended sleeve, handle rotation balance, feel good.
Fixing screws: Allen screws are used: Allen screws are used to prevent disassembly.
Lock cover: conceal the lock hole, special tools are needed to remove, beautiful and safe.
Appearance; Europe and the United States style design, within the same, without back cover.
The IC card access control system is a safe and reliable electronic door lock system. Using this system, it is convenient to manage and control the entry and exit of personnel in the application site, and to verify the identity of the personnel entering and exiting and access permissions.
The contact card locks are to be locked and the internal reader of the chip lock is contacted. The non-contact method is not to use this process. It is only necessary to tie the card and the lock reader together.
The above is a brief introduction of smart lock Chinese network Xiaobian published non-contact IC card door lock technology features, please pay more attention to the type of locks!
