Description
Technical field
The present invention relates to a kind of time service methods based on mobile phone flashlight.
Background technology
Unified time reference has great importance to the activity of the mankind, and people, which commonly obtain time device, mainly to be had
Clock and watch etc., there are regular hour errors after long time running for common time equipment（Or power down is stopped）, and these are deposited
Harmful effect will be caused to our live and work in the time device of error.Therefore need that there are the times of error to these
Equipment is calibrated（Or re-power time service）, certain time devices are using access interconnected network mode progress time service at present, still
Cost is higher, and use is complex.
Invention content
In order to improve the above problem, the present invention provides a kind of time service methods based on mobile phone flashlight.
To achieve the goals above, the present invention uses following technical scheme：
A kind of time service method based on mobile phone flashlight obtains the network standard time by mobile phone, then mobile phone is utilized to dodge
Light lamp carries out wireless time service and control to time device, to reach time calibration.
Further, the mobile phone with time device is transmitted into row information using visible light wireless communication technique.
Still further, the time device includes dodging the photosensitive sensor to match of turning off the light, the light sensor with mobile phone
Device is used to acquire the strobe signal of mobile phone flashlight.
Further, the time device further includes the time controller for regulating time, decoder, photoelectricity A/D
Converter；The decoder is connected with time controller；The photoelectricity A/D converter respectively with photosensitive sensor and decoder phase
Even.
The transmission of lamp switch realization strobe signal in addition, the mobile phone is glistened by control.
Compared with prior art, the invention has the advantages that：
The present invention is based on visible light wireless communication techniques, obtain the network standard time by mobile phone, utilize mobile phone flashlight
Wireless time service is carried out to time device, reaches convenient, flexible time calibration；Solves the time school of Code in Hazardous Special Locations time device
Quasi- problem ensures that time device accurately shows the standard time；And the present invention is at low cost, and it is easy to use.
Description of the drawings
Fig. 1 is the principle of the present invention block diagram.
Fig. 2 is the structural schematic diagram of the present invention.
Fig. 3 is the flow diagram of the present invention.
Fig. 4 is the optical communication data frame structure schematic diagram of the present invention.
Specific implementation mode
The invention will be further described with reference to the accompanying drawings and examples, and embodiments of the present invention include but not limited to
The following example.
Embodiment
As shown in Figures 1 to 3, a kind of time service method based on mobile phone flashlight is present embodiments provided, this method is to pass through
Mobile phone obtains the network standard time, then wireless time service and control is carried out to time device using mobile phone flashlight, when reaching
Between calibrate.
Specifically, the mobile phone with time device is transmitted into row information using visible light wireless communication technique.
Specifically, the time device includes dodging the photosensitive sensor to match of turning off the light with mobile phone, which uses
In the strobe signal of acquisition mobile phone flashlight.
Specifically, the time device further includes the time controller for regulating time, decoder, photoelectricity A/D conversions
Device；The decoder is connected with time controller；The photoelectricity A/D converter is connected with photosensitive sensor and decoder respectively.
Specifically, the mobile phone realizes the transmission of strobe signal by control flash of light lamp switch.
Wherein, it is seen that light wireless communication technology is that the technology of wireless data transmission is carried out using visible light, its main feature is that sharp
High speed strobe signal is generated with electric signal control illuminator to transmit information.
Time device in the present invention：By photosensitive sensor acquire mobile phone flashlight high speed strobe signal, then into
Row opto-electronic conversion, information decoding, finally by the temporal information of time controller renewal time equipment.
The workflow of the present invention is as follows：
The network standard time is obtained by mobile phone, flash lamp is then controlled and sends optical signal, photosensitive sensor acquisition flash of light
Then the optical signal that lamp is sent out carries out opto-electronic conversion and demodulation, and determines whether effective order, effective in order
It is made to determine whether that time calibration orders, finally carries out time calibration.
As shown in figure 4, the present invention provides a kind of example of data frame structure, including：
Lead code：Its effect is to inform that signal receiving end will send useful signal, and time device receiving terminal passes through leading
Code can determine whether that signal is useful signal or interference signal, is judged as then being decoded time service when useful signal, otherwise ignore not
Decoding.8 bit binary data positions can be used in its word length.Wherein mobile phone flashlight is bright indicates binary coding 1, mobile phone flashlight
Binary coding 0 can be indicated by going out.
Command word：The command type for providing flash lamp transmission data, can be indicated with 2.Such as 0 × 00 can indicate to authorize
Order, 0 × 01,0 × 10,0 × 11 can indicate other orders.
Type/length：Data type/frame length can use 8 data bit.
Data portion：Useful signal data, including standard time information, year（12）, the moon（4）, day（5）, when（5
Position）, point（6）, the second（6）, millisecond（10）.
Check bit：Error check method, the correctness for checking one group of data, judges whether difference occurs in transmit process
Whether the data bit of mistake, reception has inerrancy, can use 4 data bit.
The schematic data frame length is 70, if flash lamp flicker frequency is 1000Hz, 1ms dodges 1 time, then needs 70ms
A frame data are transmitted, i.e. time service is primary（Channel time delay can be ignored）, at this moment time service precision is 70ms.If controlling flash lamp to dodge
Bright frequency is 5000Hz, then can time service precision be risen to 14ms.
According to above-described embodiment, the present invention can be realized well.It is worth noting that before based on above-mentioned design principle
It puts, to solve same technical problem, even if some made on architecture basics disclosed in this invention are without substantive
Change or polishing, the essence of used technical solution is still as the present invention, therefore it should also be as the protection model in the present invention
In enclosing.
