When using a fingerprint lock, a light touch with your finger, press down on the handle after identification, and the door will open, which is very convenient! Do you know how the fingerprint lock works? Many unfamiliar friends always ask this question. For this question, I will provide you with a set of more detailed instructions to introduce the working principle of the fingerprint lock. The working principle of the fingerprint lock is actually very simple to sum up. Its principle is actually very similar to the principle of computer processing information.
The workflow of the fingerprint lock is simply divided into the following three steps:
Step 1: After installing the fingerprint lock, we need to enter the fingerprint of the owner of the fingerprint lock to let the fingerprint lock know who is its owner.
At this time, it is necessary to collect fingerprints for the fingerprint lock, and enter the fingerprints of all members of the family according to the instructions. Generally good fingerprint locks have a large fingerprint storage space, which can store hundreds or more fingerprint records at the same time . In this way, the work of fingerprint entry is over, which is equivalent to introducing the fingerprint lock one by one to the family, so that the fingerprint lock remembers its owner.
Step 2: The fingerprint lock intelligent system judges and processes the information input by the head of the household.
When the head of the household aligns his finger with the sensor module of the fingerprint lock and presses the fingerprint, the fingerprint lock system will perform photoelectric conversion processing on the fingerprint of the head of the household, and compare the obtained data with the information in the fingerprint database.
Step 3: The fingerprint lock system makes a judgment and executes the command.
When the information matches correctly and the fingerprint record is consistent with the fingerprint record in the database, the system judges that the fingerprint is the fingerprint of the head of the household, then it is allowed to pass, and the processed result is sent to the door lock through the power control box to open the door, otherwise, the door is not opened.
At this point, the workflow of the fingerprint lock is over.
According to scientific evidence, each person’s fingerprints are unique, no two identical fingerprints exist, even the fingerprints of twins are different. Therefore, it is very safe to use fingerprints as the "key" of the door lock.
