I. Overview of the program
The appearance of fingerprint locks solves this problem very well. It uses human fingerprint as the unlocking symbol. Through the comparison of fingerprints, combined with computer information technology, electronic technology and other technologies to open the door lock, the finger can be opened easily, the unlocking time is only 0.01 seconds, convenient and fast.
Second, the function definition and performance indicators
The smart home access control system fingerprint lock scheme consists of STC12C5A60S2 single-chip microcomputer as the main control chip, 4*4 matrix keyboard, remote control module, fingerprint module (FPM10A), 12864 display, alarm system, pyroelectric human body infrared, photoelectric switch, motor drive and so on.
Third, the program advantage
It adopts human-machine interactive menu interface, which is easy to operate and has various functions. It can be unlocked by remote control, password and fingerprint. Among them, under the password control, the correct key unlock can be input through the matrix keyboard, the password can be set, the factory setting can be restored by one key (the super user has this permission, the default password 000000), the super alarm, the super lock, and the like. Under the fingerprint control, a super user is conveniently managed to add fingerprints and delete fingerprints (superusers have this permission, including deleting the most recent fingerprint and deleting all fingerprints). In addition, it also adds functions such as human body induction, doorbell, remote control, and door switch detection.
