Accordingly, the user identification information that is stored in the storage unit in advance and can unlock the control authority of the door lock 10 further includes identification information of the user IC card. The user or related personnel can input the identification information of the user IC card in the storage unit in advance, and the user of the user IC card can perform identification verification of the identification by adopting the IC card swiping mode so as to unlock the door lock 10. The identification is carried out by adopting the mode of swiping the IC card, so that unlocking operation can be carried out rapidly and efficiently without complicated identification verification modes such as physical keys, fingerprints, faces or passwords and the like, the unlocking convenience is greatly improved, and the method is particularly convenient when a user needs to frequently enter and exit a specific area. In addition, the user or related personnel can add, delete or modify the authority of the door lock 10 of the user at any time without changing a physical key, thereby greatly improving the flexibility and convenience of unlocking the door lock 10.

In some embodiments, the door lock alarm system 12 also includes a voice module. Wherein the voice module is communicatively coupled to the controller 121. The voice module is used for broadcasting user identification prompt information, such as voice guiding the user face recognition and fingerprint recognition steps, or voice requiring the user to input a password, swipe an IC card or perform other identity recognition steps. The voice module is also used for broadcasting alarm prompt or notification information, for example, when the identification module 124 identifies and judges that the user identity fails, or abnormal unlocking activity, illegal intrusion behavior or other security problems are detected, a sound similar to a flute sound is emitted, and an alarm message is played to remind the user or security personnel. The voice module may also be used to provide voice feedback of the access status, informing the user whether access is authorized to be entered or denied. Preferably, the voice module may be a buzzer. The buzzer has the advantages of simple and reliable structure, less power consumption, low failure rate, relatively low cost, long service life and the like. The sound emitted by the buzzer is clear and distinguishable, and is particularly suitable for application environments for emitting voice alarms, reminding and indication.
