Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
Cloud based on the visible optical communication lock method for unlocking of the present embodiment, as shown in figure 1, including mobile terminal 1, intelligence
Cloud lock 2 and server 3, mobile terminal 1 and the intelligent cloud lock 2 are connected by communication network with server 3, the movement
Terminal 1 is configured with flash lamp, as shown in Figure 2：
Then step A, the matching connection of mobile terminal 1 and intelligent cloud lock 2 sets unblock close in the mobile terminal 1
Code and sending to intelligent cloud lock 2 is stored；
Step B, the unlocking pin is inputted in the mobile terminal 1, and the mobile terminal 1 turns the unlocking pin
The control data that control flash lamp flashes is turned to, the control data is unblock binary code corresponding with the unlocking pin,
And " 1 " is defined for bright light, " 0 " is to turn off the light；
Step C, the flash lamp of the mobile terminal 1 is flashed according to the control data, sends unblock optical signal；
Step D, the intelligent cloud lock 2 receives the unblock optical signal that the flash lamp from the mobile terminal 1 is sent, and
The unblock optical signal is converted into input binary code, then the intelligent cloud lock 2 inputs binary code and described by described
Unlocking pin is sent to the server 3；
The input binary code of reception is converted into input character string by step E, the server 3, and will be described defeated
Enter character string and the unlocking pin is compared：
If the input character string is identical with the unlocking pin, unlocking instruction, institute are sent to intelligent cloud lock 2
State intelligent cloud lock 2 and receive unlocking after the unlocking instruction；
If the input character string and the unlocking pin are differed, send code error to intelligent cloud lock 2 and refer to
Order, the intelligent cloud lock 2 maintains to shut state after receiving the code error instruction.
Unlocking pin is embedded into the flash of light of the mobile terminal 1 by the cloud lock method for unlocking based on visible optical communication
In the blinker of lamp, the unblock optical signal that the flash lamp of the reception from the mobile terminal 1 of intelligent cloud lock 1 is sent is simultaneously
Input binary code is translated into, input binary code is sent to the server 3 by the intelligent cloud lock 1, by the clothes
The switch that business device 3 is checked and controls the intelligent cloud to lock 1 according to checked result, thus with it is existing close by mechanical input
The authentication modes such as code, contactless card sensing are compared, and the propagation rate of the unblock optical signal can reach 100Mbps, be difficult to be stolen by people
Take and replicate, improve security.Password check process is completed in the server 3, and the intelligent cloud lock 1 only needs to complete
Unblock optical signal is converted into the process of input binary code, complicated calculating process is arranged on powerful and sustainable
Completed in the server 3 of charging, and simple calculations process is arranged on function hardly possible and is expanded and power network can not be accessed is filled
Completed in the intelligent cloud lock 1 of electricity, save the electric energy loss of the intelligent cloud lock 1, improve the arithmetic speed of password check,
It is easy to computing in the future perfect.
Preferably, as shown in figure 3, the method that the input binary code is obtained in the step D is：
Step D1, the intelligent cloud lock 2, which is preset, can handle curent change frequency and bright light current value, and described

Step D2, the intelligent cloud lock 2 receives what the flash lamp from the mobile terminal 1 was sent by photo resistance
Optical signal is unlocked, and is translated into the curent change array at the photo resistance two ends；
Step D3, the intelligent cloud lock 2 calculates the curent change frequency of the curent change array, and judges the electricity
Whether the curent change frequency of rheology array, which is higher than, can handle curent change frequency：
If then performing next step；If not then maintaining to shut state；
Step D4, the intelligent cloud lock 2 by the current value in the curent change array successively one by one with bright light current value
Compare, and in the curent change array：
If some current value is more than or equal to the bright light current value, it is converted into " 1 " in input binary code；
If some current value is less than the bright light current value, it is converted into " 0 " in input binary code；
So as to obtain the input binary code.
Due to the blinker that the unblock optical signal is flash lamp, flash rate is fast, corresponding curent change frequency
Height, and all visible rays can cause the change in resistance of photo resistance, therefore the little day by day light of light intensity change, corridor lamp
Light can allow the intelligent cloud lock 2 to produce the relatively low curent change array of curent change frequency.The intelligent cloud lock 2 will solved
Lock optical signal is simultaneously translated into before input binary code, and unblock optical signal first is converted into the photo resistance two ends
Curent change array, and its curent change frequency is compared with that can handle curent change frequency, to recognize the optical signal received
It is the blinker or other interference optical signals of flash lamp, prevents from converting non-unblock optical signal, improve identification accurate
Degree.
Because light intensity is stronger (receiving light brighter), the resistance of the photo resistance is smaller, and corresponding electric current is bigger, because
This after the unblock optical signal is confirmed as, intelligent cloud lock 2 by by the current value in the curent change array successively
One by one with bright light current value ratio compared with, you can which current value is produced when being flash lamp bright light, and which current value is that flash lamp goes out
Produced during lamp, so as to obtain the input binary code, conversion computing is simple and accurate.
Preferably, as shown in figure 4, in the step E, the server 3 is close by the input character string and the unblock
Code is compared：
