Electronic locks in the field of security technology prevention, electronic password locks with anti -theft alarm function instead of traditional mechanical password locks, overcoming the shortcomings of mechanical password locks and poor security performance, so that the password lock is technical or performance in terms of performance or performanceThe top is a great step.So what kinds of electronic locks? What should be paid attention to when buying?
Types of electronic locks
1. Key type
Enter the unlocking password with the keyboard (or combination button), which is convenient to operate.Internal control circuits often use electronic lock -specific integrated circuits ASIC.The password preset is changed by the connection between the keyboard (or combination button) and the internal control circuit.Generally, the computer memory password can reach more than 10,000 groups, and the number can be replaced arbitrarily.You can also set alarm.This lock is mostly used by anti -theft doors and anti -theft safe.
2. Dial formula
Enter the unlock password with a mechanical dial switch.Many key electronic locks can be transformed into dial -dial -type electronic locks.If the number is wrong, it will not only be opened, but the alarm circuit will also automatically connect to signal.However, this kind of lock is not as agile as the key type.
3. Electronic key type
Use the electronic key to input (or serve as) unlock passwords.Electronic key is an important part of the control circuit.The electronic key can be composed of a meta -device or a unit circuit composed of a component to make a small handheld unit.The connection between the electronic key and the main control circuit can be a variety of forms such as sound, light, electromagnetic.
4. Touch
Enter the unlock password by touching the touch method, and the operation is simple.Compared with the button switch, the life of the touch switch is long and the cost is low, so the electronic lock control circuit is optimized.The dual -metal touch point input password is used, with good concealment and strong confidentiality.There is a pseudo -key locking 5S function, which can drive the alarm.With the CMDS circuit, micro -power consumption has strong anti -interference ability.
5. Password recognition electronic lock
This electronic lock controls the switch of the lock by verifying the correctness of the input password.When entering the password errors, it has a systematic self -locking and automatic alarm.
6. Card recognition electronic lock
Card recognition electronic locks use various cards (including magnetic cards, IC cards, etc.) as the password carrier, and control the electronic lock by the corresponding card reader read card reading method.
After the magnetic card electronic lock is inserted into the card reader, the card reader reads the information in the magnetic bar and sent to the electronic lock controller. The controller can judge, execute, record and other functions according to the rules.The cost of magnetic card electronic lock is low, one person and one card, easy to use, you can connect the microcomputer to record the door opening incident, but the magnetic card and the card reader have been worn, the life span is short, and the magnetic card is easy to be copied.Interference, general safety.
The principle of IC card electronic lock is basically the same as that of magnetic card -type electronic locks, but because the IC card will not be magnetized, especially the non -contact IC cards are not in contact with the read and write device.Its difficult to copy and have high safety.
7. Biometric electronic lock
Bio -identification electronic locks use human biological characteristics as a password input, and control the opening and closing of the electronic lock by identifying the identification.Studies have shown that human fingerprints, palm lines, faces, pronunciation, iris, retinal, etc. all have unique and stable characteristics, that is, everyones characteristics are different from others and unchanged for life.Identification.
8. Wireless lock
Non -door -lock electronic locks can be used in the fields of logistics transportation, warehousing, fresh milk transport vehicles, banknote transport vehicles, refrigerated vehicles, drug transportation, tobacco transportation and other transportation fields.It is mainly used for transport vehicle doors, special car peoples Kidai and warehouse doors to ensure the safety of transportation or guarding goods, and prevent stealing behavior.
Purchase precautions
1. The function should be combined with the environment used
It is necessary to determine the functional requirements according to the application, because different use environments have different functional focus.As an electronic door lock in the financial institution office, the functions that must be available are: all key cards must have time -limited functions, locks have the door opening record function, and have a level management function.On the basic function, in order to adapt to the future development, you can consider the expansion of the lock system (the system can manage the office of the employees office, the public passage, the dedicated channel, etc.), and the technical interface of the card system.The state of the state can control the opening of the door under very incident.The best solution is the connected door lock and consider the interface of other IC card systems in order to achieve a cartoon.
2. Safety is extremely important
The door lock must be safe and stable as a security prevention product.Safety can be measured from two aspects: First, to resist the destruction of deliberate destruction, prank and deliberate prying, and drilling.In this regard, the mechanical strength of mechanical locks and electronic door locks can generally meet the requirements.Among all types of door locks, only the radio frequency card electronic door lock is a fully closed structure, and its safety is the best.The second is to prevent technology opening, and the ability of mechanical lock technology to prevent technology is very poor.Regardless of the mechanical lock of that structure, it can be opened by other means.The key can be copied is a large hidden safety hazard.In the electronic door lock, the magnetic card has no password limit, and its key card is easily copied.IC cards and radio frequency cards have completely solved the problem of prevention technology opening.
3. Stability is equally important
If you cant open the door when you open the door, you cant close the door when closing the door may bring serious losses to financial enterprises.Generally speaking, in several electronic door locks, the stability of the radio frequency card electronic door lock is significantly higher than that of other electronic door locks.The magnetic card is afraid of a strong magnetic field, and the IC card is afraid of oil, dust and static electricity (especially in dry weather with wool spinning), and the radio frequency card has the characteristics of full seal, waterproof, anti -static, and dust -proof.In terms of card reading, only the RF card reading card is not exposed, and its service life is the longest.
4. Technical development trend
IC cards can be used as identity recognition, ticket certificate, electronic wallet, etc., and the problem of inconvenient operations of contact IC card electronic door lock cards (long operation time), poor environmental adaptability, etc. It is difficult to overcomeIn public and semi -public environment, such as attendance, dining consumption, bus systems, parking lots, etc.Non -contact IC card electronic door locks are a new type of electronic door lock just produced.Because of its high reliability, high security, no contact, fast operation, and long service life, it has become a replacement product of contact IC card electronic door locks.
