Description

WIFI door lock device and using method

Technical Field

The invention relates to a WIFI door lock device and a using method thereof, and belongs to the technical field of WIFI door locks.

Background

Locks are produced almost simultaneously with proprietary systems, and the device provided for the purpose of preventing others from opening, the most effective and widespread lock applied to doors is the bolt. In ancient China, stone locks are provided, keys are not provided, and the stone locks are bound by ropes or iron chains. In the period of business week, the proprietary production of production data is further developed, the difference between poverty and wealth is further increased, meanwhile, the smelting technology is mature and is immediately applied to the lock manufacturing industry, and therefore, copper locks and iron locks which can be unlocked only by keys appear. The modern mechanical lock is characterized in that marbles with different lengths are added into a lock core, and the lock is opened by a key with a corresponding tooth form. With market demands, conventional mechanical locks face the problem of lost keys. Once the key is lost, the lock has to be changed to prevent unnecessary property loss, and the lock change not only increases the expense of the user, but also wastes resources to a certain extent.

With the rapid development of science and technology, the mechanical lock has great progress, and on the basis of the traditional key, one or more groups of passwords, different sounds, different magnetic fields, different light beams and light waves and different images are added to control the unlocking of the lock; later, coded locks, magnetic locks, fingerprint locks, voice-operated locks, etc. have been developed. At present, electronic locks occupy a large proportion in the market, but most of the electronic locks are unlocked by using the technologies of passwords, fingerprints, sounds, magnetic cards and the like. However, the electronic locks also have certain potential safety hazards, and the password has potential risk of being stolen when the password is unlocked; for fingerprint unlocking, if the hand washes clothes for a long time or is soaked in water, the unlocking cannot be performed, and the fingerprint is obtained by tools such as an adhesive tape and the like, so that the household is possibly stolen; unlocking the magnetic card, and if the user loses the magnetic card, the user is exposed to the risk of property theft; for an electronic lock unlocked by using an APP mode, a temporary password is calculated through an electronic lock cloud service platform and is distributed to a user APP and an electronic lock controller, then the electronic lock controller compares and verifies the temporary password input by a user with the temporary password stored in the electronic lock controller to unlock the electronic lock, information leakage can be caused by potential safety hazards existing in a public network, transmission errors and intermediate equipment faults can exist in a transmission process, unlocking cannot be caused, and potential safety hazards such as people restricted by unlocking can occur if the electronic lock cloud service platform and a technical provider do not provide the service any more.

In view of the above problems of the mechanical lock and the existing lock device, it is necessary to provide a more secure door lock device to meet the needs of the information age and modern life.

In the prior art, various unlocking methods are provided for a WIFI door lock, but no method for effectively unlocking the WIFI door lock by using a WIFI password, a user authority, an MAC address and a physical lock is available, for example, a device disclosed in Chinese patent (publication number: CN106652132A, published Japanese 2017.5.10) uses a WIFI control system to provide an electromagnetic wave signal for conversion for a key card and uses the key card to unlock the WIFI door lock, so that the problem that the existing electronic door lock depends on a battery as an electric quantity storage unit is solved, and the patent does not mention any method which can unlock the WIFI password, the user authority, the MAC address and the physical lock; also, as the system disclosed in the chinese patent "an intelligent door lock system based on a mobile phone MAC address and its application (publication No. CN106780901A, published japanese: 2017.5.31)", the system is connected in a broadcast manner, and can be used without establishing a WIFI connection or a bluetooth connection between a mobile phone and the door lock system.
