How does smart lock fingerprint recognition work and why does a sweaty or watery finger cause fingerprint recognition module to fail

The working principle of intelligent lock fingerprint recognition is very simple. Its principle is very similar to that of computer processing information. The workflow of fingerprint identification can be divided into three steps:

Step 1: After installing the smart lock, the head of the household needs to input fingerprints to let the smart lock know who is the owner.

At this time, we need to collect fingerprints of smart locks, and input the fingerprints of members who need to unlock authority according to the instructions. Generally, good smart locks have large storage space for fingerprints, and can store dozens or even hundreds of fingerprint records at the same time. The work part of fingerprint input is equivalent to introducing family members to intelligent locks one by one, so that intelligent locks can remember their owners.

The second step: Intelligent Lock Center Processing System judges and processes the information inputted by the head of the household.

When the head of a household press the fingerprint with his finger pointing at the sensing module of the fingerprint acquisition window of the intelligent lock, the intelligent lock system transforms the fingerprint of the head of the household into photoelectricity, and compares the fingerprint data with the information in his fingerprint database.

Step 3: Intelligent Lock Center Processing System makes judgments and executes commands.

When the information matches correctly, the fingerprint record is consistent with the database fingerprint record, and the system judges that the fingerprint is the fingerprint of the head of the household, it allows the processing results to be transmitted to the door lock through the power control box to open the door, otherwise it does not open the door.

At this point, the workflow of fingerprint lock is over.

Science has proved that each person's fingerprints are unique. There are no two identical fingerprints, even in identical twins. So it's very, very safe to use fingerprints as "keys" for door locks.

Recently, the weather has also entered the high temperature storm mode. Many small partners also said that their hands were sweating too much. The fingerprint locks at home "refused to open the door." Angel also told you today why finger sweating or finger water can lead to the failure of fingerprint identification module.

At present, there are two main ways of fingerprint acquisition by fingerprint lock, optical and capacitive (semiconductor).

1 Optical

Optical fingerprint head obtains fingerprint information by calculating the different distances of light between fingerprint trench and ridge and acquisition window. When finger has sweat stain or moisture in acquisition window, it will affect the transmission and distance of light, resulting in errors between the acquired fingerprint information and the original stored information, so fingerprint lock identification fails.

2 Capacitive type

Capacitive (semiconductor) fingerprint recognition sensors are coated with narrow electrodes around them. When the finger reaches the fingerprint acquisition window, because the human body is an electric field, the user fingerprint lines and the sensor surface will form a coupling capacitance. For high frequency current, capacitance is a direct conductor, so the finger will move from the contact point. It sucks away a very small current. This current flows out of the peripheral electrodes, and the current flowing through the peripheral electrodes is proportional to the distance from the fingerprint to the peripheral. The controller calculates the proportion of the current accurately and obtains the relevant data of touch lines. Because water is conductive, when fingerprint identification is used when finger is sweaty or window is waterlogged, the current will be affected, so the above calculation is not correct, and the natural identification is out of order.

When users first enter fingerprints, they must keep their fingers and fingerprint acquisition windows dry and clean so as to input correct and clean fingerprints. When users use fingerprints to unlock, drying fingerprints and acquisition windows can avoid most of the fingerprint identification failure.
