An intelligent terminal light-controlled door lock system and its application method

Abstract

The present invention is an intelligent terminal light-controlled door lock system and its use method. The light-controlled door lock control terminal of the system is an intelligent terminal of a smart phone, a tablet computer or a handheld computer, and its light-controlled door lock key management module has unlocking and password Set up the unit. Light-operated door locks are equipped with microcontrollers with door lock memory, mechanical locking devices with mechanical keys and / or unlock buttons. The method of use is that when the key is set, the door lock is opened, the smart terminal enters the built-in machine code and password information of the door lock, and binds with the serial number of the smart terminal to form a combined key, which is transmitted to the light-controlled door lock, and the door lock receives and analyzes to confirm and store the unlock password information. When unlocking, after the smart terminal enters the password information authentication, the combined key is encrypted to generate the unlocking security key, and after modulation, the flash light is emitted, and the light-controlled door lock receives and decrypts to confirm the unlocking. The invention is convenient to use without an optical signal transmitter, and the transmission of the optical signal key is safe and fast; the unlocking key has numbers and letters and identification information and can be modified to ensure safety.

Description

technical field [0001] The invention relates to the technical field of light-controlled door locks, in particular to an intelligent terminal light-controlled door lock system and a use method. Background technique [0002] As a daily necessities for ordinary people, door locks are a necessary tool to ensure the privacy and safety of people's lives. Traditional mechanical door locks are still widely used in the market. As an upgraded application of mechanical door locks, electromagnetic induction door locks, infrared control, wireless control and light control door locks have become more common in recent years. Although the door locks with these new functions are safer than the mechanical door locks, they still need a special unlocker, and the copying of the unlocker also requires special facilities. Since the unlocker can be copied, the security is low. [0003] At present, the smart door locks on the market are based on smart terminals and smart door locks based on specia...

AI Technical Summary

Problems solved by technology

Its defect is that each light control door lock system is equipped with a limited number of dedicated optical signal transmitters during production. When the optical signal transmitter is damaged or lost, it is difficult to reassign a suitable optical signal transmitter. Device, affect the use of light control door lock system

In addition, the unlock key cannot be changed by the customer, and the security of the long-term use of the light-controlled door lock system will decrease.
