Smart fingerprint lock technology, how much do you know?

The principle of fingerprint lock technology refers to the uneven lines on the frontal skin of the fingertips. Although the fingerprint is only a small part of the human skin, it contains a lot of information. These lines are different in patterns, breakpoints, and intersections. They are called "characteristics" in information processing, and it has been medically proven that these features are different for each finger, and these features are unique and permanent.

Therefore, we can associate a person with his fingerprint and verify his true identity by comparing his fingerprint features with pre-saved fingerprint features. Therefore, the above features of fingerprints have become the most important evidence for identification and are widely used in public security criminal investigation and judicial fields.

Second, no matter what lock, its essence is still a mechanical product. Fingerprint lock is a model of using modern high-tech to transform traditional industries. Its core technology is firstly the grasp of mechanical technology. Mechanical technology mainly consists of the following aspects:

1. Reasonable design of front and rear panels

In other words, the appearance is a sign that is significantly different from similar products. The more important internal structure layout directly determines the stability and function of the product. This process involves design, mold making, and surface treatment. Therefore, the more style manufacturers, relatively speaking, more development and design capabilities, better stability.

2, lock body

That is, the mother tongue of the lock tongue that can be associated with the door. The quality of the lock body directly determines the life of the product. This is the most core technology in mechanical technology and the lifeblood of fingerprint locks. It is also the most difficult problem to solve in the industry. 95% of the existing production units can not solve this problem, mainly through the way of outsourcing. Strong manufacturers own their own ability to design and develop locks. Therefore, the lock body is a core component that truly embodies the technical level of the manufacturer and is the core technology of the entire fingerprint lock.

3, motor

The motor is a driver. Just like the computer's driver software. It is the connecting device of electronics and machinery. It is the transforming center of power and plays a major role in the connection. If the motor stops working or an obstacle, the lock will automatically open and cannot be locked.

4, fingerprint module and application system

This is the basis of the electronic part. Fingerprint module, the current counterpart function is almost the same, mainly to see which chip is used, which is the use of the algorithm, such as Sika's algorithm chip, after long-term market verification, the effect is very good.

5, circuit design

Clear circuit design and wiring are also important factors in ensuring product stability.

6. Fingerprint recognition algorithm

At present, the identification algorithm of general fingerprint products is completely the core algorithm of our company's own intellectual property rights, and the entire corresponding technical indicators have reached the world's leading position, among which: false recognition rate (misrecognition rate): <0.0001%: one hundred One ten-thousandth, that is, the probability of accidental unlocking; refusal rate: <0.3%: three-thousandths, that is, the chance of refusing to unlock after you store fingerprints; rotation angle: plus or minus 180 degrees, that is, can be 360 ​​degrees Arbitrary rotation; maximum translation: 5mm; identification time: <0.2s, fingerprint comparison processing time.

Smart fingerprint lock is currently the most widely used smart lock. It is believed that more types of smart locks will enter the user's home in the future.
