Lock head dragon fingerprint lock new generation fingerprint technology leader

Fingerprint lock is a kind of intelligent lock with human fingerprint as the identification carrier and means. It is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. The fingerprint lock is generally composed of two parts: electronic identification and control, and mechanical linkage system. The uniqueness and non-replicability of fingerprints determine that fingerprint locks are the safest locks in all current locks. In addition to fingerprint identification, fingerprint locks should be equipped with emergency mechanical keys according to national regulations. The product quality specification is based on the "Public Safety Industry Standard of the People's Republic of China <General Technical Conditions for Fingerprint Anti-theft Locks> (GA701-2007)".

Fingerprint lock, the new generation of fingerprint technology leader

Fingerprint refers to the uneven texture on the front side of the finger. Although the fingerprint is only a small part of the human skin, it contains a lot of information. These lines are different in pattern, breakpoint and intersection. They are called "features" and they have been medically proven to be different for each finger, and these features are unique and permanent, so we can associate a person with his fingerprint by comparing His fingerprint characteristics and pre-saved fingerprint features can verify his true identity. Therefore, the above characteristics of fingerprints have become the most important evidence for identifying identity and are widely used in public security criminal investigation and judicial field. Fingerprint authentication is convenient, fast and accurate.

According to the anti-theft performance classification, the current popular fingerprint locks are divided into two types: ordinary fingerprint locks and fingerprint anti-theft locks. Ordinary fingerprint locks are not much different from the original electronic locks. The main purpose is to use fingerprint authentication, but it is not used for existing domestic security doors. This type of fingerprint lock does not have the hooks of the heaven and earth, and cannot use the security door security system (all imports). Fingerprint locks are not in line with national industry standards and can only be used for wooden doors). The other type, the fingerprint anti-theft lock, has better security, can be applied to the standard anti-theft door, and automatically or semi-automatically couples the security door with the heaven and earth lock system, and does not affect the performance of the original security door.

According to the identification carrier division, the fingerprint lock can be divided into optical fingerprint lock and semiconductor (capacitive, pressure bar and thermal sensor) fingerprint locks. The optics are relatively stable and adaptable, and are mostly used in anti-theft locks; the semiconductor is relatively small in size, and the recognition range is wider than that of the optical, especially for dry fingerprint users. However, semiconductor fingerprint locks have higher requirements on the use environment and are easy to scratch and scrap. It is generally used in special care places (such as banks) and products (such as mobile phones, laptops). Both materials have their own advantages and disadvantages. In general, they are: optical is afraid of drying, and semiconductors are afraid of humidity.

In the market, in addition to fingerprint recognition, some have the function of adding a password, so this kind of fingerprint lock is also often called fingerprint password lock. The fingerprint, password and emergency key can be turned on separately. The password function depends on the security setting. The password length is between 4-12 digits. The numeric keys generally use 0-9 full digital input mode.

In addition to the door opening function, the fingerprint lock generally has the function of adding, deleting or clearing the fingerprint. The high-performance fingerprint lock is also equipped with a human-machine dialogue system such as a liquid crystal display, which has a high level of intelligence, relatively convenient operation and provides operation guidance. Query usage records and built-in parameters, set status, and more. Fingerprint management generally implements hierarchical management. The administrator has all the functions of opening the door, adding fingerprints, deleting fingerprints, clearing fingerprints, querying usage records, setting system parameters, etc., while ordinary users only have the function of opening the door.

The power supply method of the fingerprint lock generally adopts four 5th alkaline batteries, which can generally be used for one year or so (depending on function, power consumption design, number of uses, etc.). According to the industry standard production of anti-theft fingerprint lock, it should be equipped with an emergency power supply interface, which can be powered by 9V laminated battery. Both battery manufacturers are available for sale.
