With the advancement of society and the improvement of living standards, ordinary people have higher and higher requirements for safety and privacy. The Ministry of Construction's Housing Industrialization Office once proposed that the minimum functional requirement for intelligent community and home intelligence is to realize the “three defenses†function in the family house; namely: “anti-theft, disaster prevention, and accident preventionâ€. In recent years, people have been trying to use various modern technologies to achieve enhanced security. The application of biometrics technology has become more and more powerful and intelligent. The fingerprint lock will become the IC card lock and the induction card door. The new protagonist of the electronically controlled lock after the lock.
For fingerprint recognition technology, in the past, people only learned about it in TV dramas and science fiction movies. In recent years, with the rapid development of computer technology and the rise of research technology research in the field of biometrics, fingerprint recognition technology has gradually moved toward A wide range of civilian markets have begun to appear in people's lives and are beginning to be known to the public.
According to archaeological findings, as early as 7000-6000 BC, ancient Assyrians and Chinese people realized the characteristics of fingerprints and applied them to the signing of contracts and contracts. By the middle of the 19th century, people began to study fingerprints and produced two important conclusions: 1. Uniqueness: the shape of fingerprint lines without any two fingers is consistent; 2. Invariance: fingerprint lines The form is life-changing.
The use of fingerprint door locks is widespread in every field of every industry, ordinary households, high-end villas, office spaces, schools, hotels, etc. The biggest function is safe and convenient. Its appearance is sleek and simple, and the high-end atmosphere is favored by many consumers. More and more people are beginning to understand the fingerprint lock, and more people will like the value brought by the fingerprint lock.
In recent years, fingerprint locks have slowly entered thousands of households. With the slow innovation of locks, the maintenance of locks has become more and more important. Today, experts should tell you some tips for daily maintenance of locks. Your home is safer and the locks are more handy.
1. When installing the lock, do not use paper or tape on the handle and the panel. Do not install the paint on the door when it is not dry. Otherwise, the surface will be damaged and the color will fade after a long time.
2. Some zinc alloys and copper locks have a "spot" on the door for a long time. This is not rust, but oxidation. Just wipe it with a special oil for the lock to remove the "spot".
3. Keep the lock body clean to prevent foreign matter from entering the lock cylinder and causing it to fail to open. When the lock is difficult to open, do not lubricate it with cooking oil to avoid blockage caused by solidification for a long time.
