Embodiment l

[0027] Embodiment 1 is an NFC smart home door lock.

[0028] As shown in FIG. 1, an NFC smart home door lock according to an embodiment of the present invention includes an NFC smart lock body, a smart phone and a smart home router.

[0029] The NFC smart lock body includes a battery module, a WIFI module, an NFC password unlocking module, a password unlocking module, a key unlocking module and a fingerprint unlocking module.

[0030] The NFC password unlocking module includes three groups of NFC devices. Each group of NFC devices has two modes: the master device mode and the slave device mode. The master device mode provides a radio frequency field during the entire communication process, and the slave device mode does not generate a radio frequency field. The electromotive force provides the power required for work, and uses load modulation for data transmission and reception.

[0031] When the NFC smart lock is in standby mode, the NFC password unlocking module works in sl...

Embodiment 2

[0039] Embodiment 2 A method of using an NFC smart home door lock.

[0040] Such as figure 2 As shown, a method for using an NFC smart home door lock according to an embodiment of the present invention, the steps are as follows.

[0041] A. The smart phone and NFC smart home door lock set the NFC smart home door lock parameters through WIFI, and set the mobile phone NFC module authority and password. Assume that the password is expressed as "111110000000" in binary numbers, that is, "3968" in decimal numbers.

[0042] B. Before returning home, the user takes out the smartphone, presses the power button and the volume up and down buttons simultaneously with the middle finger and index finger to activate the NFC mode of the phone.

[0043] C. Put the NFC module of the smartphone on the NFC device that is valid on the day of the NFC smart home door lock; if it is misplaced, the lock cannot be unlocked, and the NFC smart home door lock will notify the user through WIFI; The sla...

Abstract

An NFC intelligent household door lock comprises an NFC intelligent lock body and a smart phone, wherein the NFC intelligent lock body comprises a battery module, a WIFI module, an NFC password unlocking module, a password unlocking module, a key unlocking module and a fingerprint unlocking module; the NFC password unlocking module comprises three sets of NFC equipment; each set of the NFC equipment has a master equipment mode and a slave equipment mode; the master equipment mode provides a radio frequency field in the whole communication process; the slave equipment mode does not produce a radio frequency field; a power supply required for work is provided by inducing an electromotive force of master equipment; and data transceiving is performed by load modulation. When the NFC intelligent door lock is in a standby state, the NFC password unlocking module works in the slave equipment mode without the power supply; and when an NFC module of the smart phone approaches the NFC password unlocking module via the master equipment, the NFC password unlocking module in the slave equipment mode receives an unlocking request, and the master equipment mode is triggered and started.

Description

technical field [0001] The invention relates to a smart device connected to a network, a smart home, the field of security technology, and the field of NFC technology, and in particular to an NFC smart home door lock and a use method. Background technique [0002] At present, household smart door locks generally use 4 unlocking methods: fingerprint unlocking, Bluetooth unlocking, password unlocking, and key unlocking. The time is slower than NFC unlocking, and it is convenient to unlock directly without an NFC card, but few smart door locks use mobile phone NFC to unlock. Entering the password on the screen or on the lock is more troublesome than the four unlocking methods. In addition, the NFC of the door lock needs to be used as the NFC master device to provide a radio frequency field during the entire communication process, that is, it needs to be in the state of transmitting radio frequency for 24 hours, which is more expensive. Electricity, while household door locks u...
