Application method of intelligent fingerprint lock based on STM32 and intelligent fingerprint lock module thereof
The invention relates to an STM32-based intelligent fingerprint lock use method and an intelligent fingerprint lock module thereof. The STM32-based intelligent fingerprint lock use method comprises the following steps: S11, fingerprint recording: performing fingerprint recording on a fingerprint lock twice: performing fingerprint recording for the first time, recording characteristic values of fingerprints, performing fingerprint recording for the second time, performing similarity comparison with the first time, and performing fingerprint recording for the second time; after the comparison is passed, the WiFi stores the characteristic value in a database of a server side; the fingerprints are compared with fingerprints in the fingerprint database, when the same data exist in the fingerprint database, the lock is unlocked, and when the same data do not exist in the fingerprint database, the lock is not unlocked. The intelligent fingerprint lock has the beneficial effects that 1, fingerprints are recorded in various modes, namely, the fingerprints can be recorded through the fingerprint module of the intelligent fingerprint lock and can also be recorded through the mobile phone terminal, and user operation is facilitated; and 2, the lock is unlocked in various modes, so that a user can unlock the lock under various conditions, and the embarrassing condition that the lock cannot be unlocked is avoided.
本发明涉及一种基于STM32的智能指纹锁的使用方法及其智能指纹锁模块，包括以下步骤：S11.录指纹：对指纹锁进行两次指纹录制：第一次指纹录制，记录指纹的特征值，第二次指纹录制，与第一次进行进行对比相似度，对比通过后WiFi会将特征值保存在服务器端的数据库中；S21.刷指纹：将指纹和指纹库中的指纹进行对比，当指纹库中存在相同的数据，则开锁，当指纹库中不存在相同的数据，则不开锁。本发明的有益效果在于：1、通过多种方式录入指纹，即可通过智能指纹锁的指纹模块进行指纹的录制，也可通过手机端进行指纹的录制，方便了用户操作；2、通过各种方式进行开锁，可满足使用者在各种情况下进行开锁，避免了开不了锁的尴尬的情况的发生。
