After door lock detects the distance between mobile device and door lock, door lock judge the distance whether be less than it is default away from
From.When the distance between mobile device and door lock are less than pre-determined distance, the NFC Energy extraction circuits of door lock are received by NFC
Energy in its line drawing mobile device.
Wherein, NFC reception antennas are operated in 13.56MHz (Mega Hertz, megahertz) frequency range, the number of NFC reception antennas
Can be 106kbps (bit rate), 212kbps or 424kbps according to transmission rate, it is recognized reading distance in most applications, not surpassed
Cross 10 centimetres.
NFC Energy extractions circuit is used for the energy for extracting the mobile device for carrying NFC function.In embodiments of the present invention,
By the structure of MAC (Media Access Control, the medium access control) layer for changing NFC, and radio frequency, antenna,
Low-power consumption, zero energy configuration etc. optimize, to increase the receiving power of NFC Energy extraction circuits.Specifically, low-power consumption is passed through
Technology, antenna matching technique etc. optimize.It can be obtained by experiment, the receiving power of NFC Energy extraction circuits can increase to
More than 60mW (megawatt).
Further, when the distance of mobile device and door lock is more than or equal to pre-determined distance, NFC Energy extraction circuits
Pass through RF energy of the NFC reception antennas extraction less than mobile device.
Step S30, based on the power circuit of the door lock, powered by the energy to the door lock.
After the energy of the mobile device of the NFC Energy extraction circuit extractions of door lock, the energy extracted is transferred to electricity
Source circuit.After power circuit receives energy, powered according to the energy to door lock.Wherein.Power circuit is a kind of LDO (low
Dropout regulator, low pressure difference linear voltage regulator), provide power supply for each circuit and the module work to door lock.
Step S40, after electricity on the door lock, if detecting, the enabling that the mobile device is sent by NFC function refers to
Order, then the door lock is opened according to the door open command.
After electricity on door lock, door lock detects whether to receive the door open command that mobile device is sent by NFC function.Work as door
After interlocking receives the door open command that mobile device is sent by NFC function, the microprocessor of door lock is opened according to the door open command
Door lock.Wherein, microprocessor is arranged in main control module, and power circuit is connected with main control module.Specifically, as the NFC of door lock
Energy extraction circuit extracts the RF energy of mobile device by NFC reception antennas when realizing the powered operation of door lock, mobile
Application program launching password input function corresponding with door lock in equipment, user is prompted to be inputted in the application program of mobile device
Door-opening password.After user inputs door-opening password in a mobile device, mobile device triggering door open command, and opened what is triggered
Door is sent to door lock by NFC function.
Further, after user inputs door-opening password in mobile device application program, mobile device can verify user
Whether the door-opening password of input is correct.Specifically, when the door-opening password of user's input and enabling that mobile device prestores are close
When code is consistent, then confirm that the door-opening password of user's input is correct；When the door-opening password of user's input prestores with mobile device
Password it is inconsistent when, then confirm user input door-opening password mistake.Wherein, door-opening password includes but is not limited to finger-print cipher
And numerical ciphers.When the door-opening password of user's input is correct, mobile device triggering door open command, will be taken by its NFC function
Door open command with door-opening password is sent to door lock.
Further, after electricity on door lock, door lock can also open door lock using following three kinds of modes.
1. after electricity on door lock, door lock detects whether to receive the instruction of swiping the card of corresponding contactless card.If receive
Swipe the card instruction, door lock opens door lock then according to the instruction triggers door open command of swiping the card according to the door open command.Wherein, sense
Block the NFC label badge carried for user, the door lock is opened for being swiped the card in door lock.Contactless card can be IC (integrated
Circuit, integrated circuit) card, or TM (Touch Memory) cards etc..
2. being provided with the touch key-press module being connected with microprocessor in door lock, touch key-press module connects with touch panel
Connect.After electricity on door lock, user can input the door-opening password needed for opening the door to open door lock on touch panel.It is appreciated that
It is that door-opening password now is numerical ciphers.After user is inputting door-opening password on touch panel, door lock detects that enabling is close
Code, door open command is triggered by door-opening password, to open door lock.In the present embodiment, touch key-press module can use 12 tunnels
Capacitance touch chip, in other embodiments, the touch chip that touch key-press module can also take other form, herein no longer
Repeat.
3. the fingerprint input module being connected with microprocessor is provided with door lock, fingerprint input module connection fingerprint input face
Plate.After electricity on door lock, user can input the fingerprint needed for opening the door by fingerprint TIP.When user passes through fingerprint input face
After plate input fingerprint, fingerprint input module detects the enabling fingerprint, and triggers door open command by the enabling fingerprint, to open
Door lock.
Further, user can also set one or more finger-print cipher by fingerprint TIP, by set
The finger-print cipher put is to open door lock.
The present embodiment passes through when the inspection for the mobile device and the distance between the door lock for detecting detection carrying NFC function
After surveying instruction, according to the distance between mobile device and the door lock described in the detection command detection；If the distance is less than
Pre-determined distance, then pass through the energy in mobile device described in the NFC reception antennas and NFC Energy extraction circuit extractions of the door lock
Amount；Based on the power circuit of the door lock, powered by the energy to the door lock；After electricity on the door lock, if detection
The door open command sent to the mobile device by NFC function, then the door lock is opened according to the door open command.Make door lock
Do not need battery, by NFC directly using mobile device energy power, to open door lock, avoid when the lithium in door lock from
After sub- battery or dry cell electricity exhausts, user do not open door lock situation occur.Further, due to not needed in door lock
Battery, therefore during door lock is made, it is not required that the headspace placing battery on door lock, reduce being fabricated to for door lock
This.Further, because door lock does not have battery, therefore door lock battery drain is it also avoid, door lock battery charges situations such as on fire
Occur.
