Emergency unlock system of electronic door lock and implementation method thereof

Abstract

The invention relates to an emergency unlock system of an electronic door lock and an implementation method thereof. The emergency unlock system of the electronic door lock comprises a buzzer, a key switch, a vibration switch, a micro controller unit and a power supply. When emergency unlocking is needed, a preset unlock password of a user is input through the method of knocking at a door outsidethe door. When the password is judged correct by calculating with the micro controller unit, an unlock signal is transmitted to drive a motor to unlock. According to the emergency unlock system of theelectronic door lock, the system is simple in structure and few in component, and can be embedded in any electronic door lock circuit to achieve the aim of emergency unlocking. By adopting the system, a mechanical lock core for emergency can be completely abandoned, and no keyhole is needed, so that the door lock security is enhanced, and the user experience is improved.

Problems solved by technology

[0002] The safety performance of traditional mechanical door locks is poor, and it is easy to be opened by criminals. There is a great potential safety hazard, and it is necessary to carry the mechanical key with you, which also brings some inconvenience to people's lives.

With the development of the times, all kinds of electronic door locks have begun to replace mechanical door locks. Currently, the more popular electronic door locks include fingerprint locks, remote control locks, card-swipe locks, face-swipe locks, code locks, and smart locks controlled by smartphone APPs. Locks, these electronic door locks have improved safety and convenience to a certain extent, but as electronic products, there are also problems with electronic failures, so how to unlock them in an emergency when an electronic failure occurs? Generally, manufacturers of electronic door locks provide a set of mechanical lock cylinders and mechanical keys for emergency use. Although the security level is higher than that of ordinary lock cylinders, or the installation location is somewhat concealed, it is still reserved for criminals after all. Unlocking technology is possible, and users have to carry the emergency key at all times, which greatly reduces the safety and convenience of electronic door locks
