Intelligent prompting and sound producing lock

Abstract

The invention discloses an intelligent prompting and sound producing lock which comprises a gravity sensor, an infrared sensor, a buzzer, a mobile phone control module, an electronic information module, a speaker, a normally-closed relay, a dock operation unit, a communication module, a cloud server and a remote control module. The intelligent prompting and sound producing lock is characterized in that when a user is at home, a contact switch of the normally-closed relay is closed, and normal power supply of household appliances is guaranteed; when the user goes out and double locks the door, a microprocessor provides a power-off control signal to control the contact switch of the normally-closed relay to be disconnected, a power supply circuit of the household appliances is automatically cut off, waste of electricity is avoided, and electrical safety is guaranteed. Remote control can be realized, the lock state can be controlled conveniently by the user in different places, dynamic information around the lock is known in real time, safety of the lock is improved, and personal property security and personal safety of the user are well protected.

Description

technical field [0001] The invention relates to the technical field of smart devices, in particular to an intelligent prompting and sounding door lock. Background technique [0002] An electronic combination lock is an electronic product that controls the operation of a circuit or a chip through a password input, thereby controlling the closing of a mechanical switch, and completing the tasks of unlocking and locking. There are many types of electronic combination locks, including simple circuit products and chip-based products with high cost performance. In the field of security technology prevention, the electronic combination lock with anti-theft alarm function replaces the traditional mechanical combination lock, which overcomes the shortcomings of the mechanical combination lock with less passwords and poor safety performance, and makes the combination lock both technically and in performance. A big step up. With the development of large-scale integrated circuit techn...
