Number poor scene possibly can not normal use.
Existing bicycle smart lock, which is substantially, now is scanned two dimensional code, unlocks to obtain password.But
Two dimensional code category code encoding/decoding mode, cheap, unidirectional, the auto-changing of two dimensional code when can not be used offline, from without offline
The security context used is unsuitable for using offline.(offline use refers to that bicycle not move by access to mobile network, mobile phone access
When network can also open and close lock bicycle)
And the bicycle lock unlocking cipher obtained, it is simple and fixed, it is easy to be stolen by the external world, if carrying out artificial regular
Change password, can also take a substantial amount of time and energy, is not the choosing of wisdom.
In view of disadvantages described above, it is necessary to design a kind of smart lock based on NFC and change close control method offline.
Summary of the invention
In view of the above-mentioned problems, the object of the present invention is to provide a kind of shared offline shape of bicycle smart lock based on NFC function
The control method of Modify password under state, number.Code generator and close is placed in the bicycle intelligent bicycle lock with NFC function
Code generator can change number and password by change directive under off-line state at random, improve fixed password leakage
Defect, the behavior taken into one's own possession after preventing criminal from stealing bicycle information.To achieve the above object, the present invention takes following
Technical solution:
A kind of smart lock based on NFC changes close control method offline, is all had using the mobile phone and intelligent bicycle lock of the method
NFC communication function includes password generator and code generator in intelligent bicycle lock, changes close control method offline are as follows:
1) when preparing to shut, by mobile phone close to intelligent bicycle lock, change directive is sent to intelligent bicycle lock.
2) after intelligent bicycle lock receives instruction, while lock inner cipher generator starts, code generator also comes into force, vehicle
The password and number of lock change simultaneously into new, and new lock password and number are sent to mobile phone by NFC by intelligent bicycle lock, and
Background management system is sent to by mobile phone.
3) background system is inquired, by new number and password update original database information if this new number is available,
Instruction will be shut simultaneously and is sent to lock via mobile phone, will be completely shut, if number is used by another vehicle, backstage will
It is saved after another number encryption through being sent to lock by mobile phone, while carrying out the update of backstage bicycle information database,
In case obtaining bicycle information when next user's use, and instruction will be shut and be sent to smart lock completion also by NFC mobile phone
It shuts.
The invention adopts the above technical scheme, which has the following advantages:
(1) present invention uses password generator, can be by NFC mobile phone close to transmission in the state that lock is offline
Change directive automatically generates new password.Bicycle lock password can be shared with effective protection to leak, and only user is needed to use
Change directive is sent when finishing, and bicycle is made to automatically generate new password.Safety is saved worry, and the triviality of consistency operation is simplified,
Reduce password periodic modification management cost.
(2) present invention uses code generating method device, starts to work while password starts and converts, and changes bicycle and compiles
Number.The protection of bicycle lock is further enhanced, the drawbacks of cracking lock password according to fixed number is prevented.
(3) bicycle lock of the invention can complete the operation of Modify password when offline, prevent lock SIM card from believing
When number difference, the drawbacks of lock password, number can not be changed, to be bicycle offline using providing security context.
(4) new password and number are sent to mobile phone by NFC function, together in the state that lock is offline by the present invention
The bicycle information received is sent to background management system, the original database of background update, in case next by Shi Shouji
User obtains.It prevents under off-line state, do not timely update data from the background, causes next user that cannot normally unlock.
