Tianjin anti-theft lock winter battle
Since the beginning of winter, many users who use smart fingerprint locks have a common feeling that they often fail to compare when using fingerprints. It's unpleasant to feel that the winter is shut out. What is the reason?
The secret mainstream fingerprint collection and identification technology that takes you to see the smart fingerprint lock has the following types:
Optical Fingerprint Acquisition Technology Currently, smart locks are used in a wide range of fingerprint acquisition technologies. After many years of development, optical acquisition devices have their own advantages, such as strong environmental adaptability, which can adapt to a certain degree of temperature change, and high resolution under normal conditions. The sensitive speed of fingerprint recognition is less than or equal to one second. Like most of the fingerprint readers we usually use at work, we use optical fingerprint acquisition technology.
However, optical fingerprinting is also inadequate. The biggest drawback is that the degree of finger recognition in winter has dropped significantly.
Semiconductor Fingerprint Acquisition Technology The semiconductor fingerprint acquisition technology is based on a “flat†integrated with tens of thousands of semiconductor devices. The finger is placed on it and it forms the other side of the capacitor (inductor). Because the finger plane is uneven, the bumps are The actual distance between the contact plate and the pit is not the same, and the formed capacitance/inductance value is not the same. According to this principle, the device collects the different values ​​collected to complete the fingerprint collection.
This principle makes the semiconductor fingerprint sensor have the advantages of small size and high recognition rate. We have used smart phones, and many brands have applied this unlocking technology. The newly upgraded smart lock also uses semiconductor fingerprint acquisition technology. According to customer feedback we received, most users have used fingerprints to unlock and have not been affected by the weather since the winter.
It is very simple to verify the failure of fingerprint verification in winter. Before entering the fingerprint on the smart lock, put your finger on the mouth to make it moist, or put it in grease or a relatively moist place such as the forehead. Fingers, generally so that you can solve the problem of fingerprint drying. It is best to wear warm gloves when you go out, which will help prevent the fingers from drying out.
Through the above solution, it is generally possible to solve the problem of frequent failure of the fingerprint lock in autumn. Compared with general fingerprint locks, smart locks can not only have fingerprint verification functions, but also have four other unlocking methods: magnetic card unlocking, fingerprint unlocking, key unlocking and remote unlocking.
Smart locks can be unlocked in a variety of ways. Each functional area operates independently. Even if one of the unlocking methods fails, it does not affect the use of other functional areas. This not only effectively avoids the troubles caused by the failure of the verification of autumn and winter fingerprints, but also makes it easier for the elderly and children to collect and use them. The group of fingerprints.
