Description
Technical field
The invention belongs to field of security technologies, and in particular to a kind of door-locking system and door lock controlling party based on wireless charging
Method.
Background technique
The first line of defence of the door-locking system as house security, selection one are particularly important the door lock of safety.In modern section
Under the increasingly developed background of skill, intelligent electronic lock comes into being.
What intelligent door lock was different from traditional mechanical door lock is a little that mechanical door lock is with key unlocking, and intelligent door lock is
To use on-mechanical key door lock for mark, electronic circuit, computer technology, mechanical assembly technique are combined in one
Modernize scientific and technological door lock.Intelligent fingerprint door lock using everyone fingerprint characteristic be it is unique, without repeat etc. properties, cooperation
Optical sensor acquires fingerprint, is realized and is unlocked using fingerprint identification technology.With programmable logic device (FPGA) for design vector
Cipher electronic door lock, be use all kinds of cards as verifying password, the card identified by permission of the reader to card
Piece electronic lock.Intelligent electronic lock eliminates the deficiency of tradition machinery door lock to a certain extent, solve people it is outgoing when
Carry the worry of metal key.
After 2010, intelligent door lock is also answered other than traditional mechanical lock, IC card password, by biological identification technology
It uses in intelligent door lock, such as: the technologies such as recognition of face and iris recognition, at the same it is a in also adding in appearance for intelligent door lock
Property element design.In recent years, with Internet of Things, smart home it is burning hot, intelligent door lock is also natural and smart phone is bundled in
Together, there is " app+ intelligent door lock " or " wechat+intelligent door lock " isotype.
Wireless charging technical application into door-locking system, is involved following technology by the present invention:
1, wireless charging has the advantages such as convenient, safety is high, is generally divided into following 4 kinds: 1) inductance type wireless charging skill
Art is based on electromagnetic induction principle, and primary coil has the alternating current of certain frequency, generates one in secondary coil by electromagnetic induction

The person of sending and recipient use same key, only lock to data, and then attacker and locking person require with same
Key be unlocked and lock；Asymmetry encryption technology generally uses public key encryption algorithm, what public key encryption algorithm used
It is a kind of algorithm based on mathematics, is broadly divided into RSA and ECC two ways, key is encrypted and protected by public key encryption algorithm
It is close to be combined together, so that the management and granting enhanced convenience of key.
3, mobile communication refers to the communication carried out between mobile subscriber or between mobile subscriber and fixed user.Relative to 3G
The channel of the communication technology, the channel bandwidth of the 4G communication technology have reached relatively high level, can be in the branch of channel functions
It holds down, with the multiple media communication services of period transmission, 4G communication technology traffic rate is then up to 150Mbps or more, now
5G communication also starts to come into operation；Bluetooth wireless technology is a kind of wireless technology standard, it can be achieved that fixed equipment, movement are set
The standby short-range data between building personal area network exchanges (using the UHF radio wave of the ISM band of 2.4-2.485GHz)；
RFID (radio frequency identification) is one contactless by Space Coupling (alternating magnetic field or electromagnetic field) realization using radiofrequency signal
Information is passed through the technology that transmitted information reaches identifying purpose；NFC (Near Field Communication, i.e.,
Wireless near field communication) it is a kind of emerging technology, use the equipment (such as mobile phone) of NFC technique can be close to each other
In the case of carry out data exchange, be by contactless RFID and interconnection and interflow technology integration be evolved, by one chip
Upper integrated induction formula card reader, the function of icah wavw and point-to-point communication realize mobile payment, electronics using mobile terminal
The application such as ticketing service, gate inhibition, mobile identification, anti-fake.
