Data transmission method between the subscriber equipment of the present invention as shown in Figure 2, may further comprise the steps:
Step 200: when needing the transmission data, first subscriber equipment is set up optical communication by visible light signal with second subscriber equipment and is connected;
Particularly, when needing the transmission data, any one subscriber equipment that participates in two subscriber equipmenies of communication sends the visible light detecting signal to another subscriber equipment, after the subscriber equipment of receiving detectable signal determines that the check code of visible light detecting signal is correct, send the responsive to visible light signal to the subscriber equipment that sends the visible light detecting signal, connect thereby set up optical communication;
Wherein, the subscriber equipment that sends the visible light detecting signal both can be a data receiver, also can be the data receiver, and corresponding, the subscriber equipment of receiving the visible light detecting signal both can be the data receiver, also can be data receiver;
Visible light detecting signal and responsive to visible light signal are the visible light signal of high frequency, when practical application, the visible light signal that visible light detecting signal and responsive to visible light signal are high frequency can be set in advance; The visible light signal of described high frequency is meant that frequency is the above visible light signal of 200Hz; The visible light detecting signal comprises check code; Whether correct the check code of determining the visible light detecting signal whether correct concrete processing procedure can adopt existing definite check code arbitrary method, such as: cyclic redundancy check (CRC) (CRC, Cyclic Redundancy Check) method etc.; The both sides of communication can arrange to determine the whether correct method that adopts of check code in advance;
After receiving the responsive to visible light signal, show that then described first subscriber equipment set up optical communication with described second subscriber equipment and be connected;
When practical application, every interval T 1 duration can be set, described first subscriber equipment and described second subscriber equipment all detect the visible light signal of high frequency, that is: visible light detecting signal, if receive the visible light detecting signal, and after the check code of determining the visible light detecting signal is correct, send the responsive to visible light signal to the other side; If do not receive the visible light detecting signal, then send the visible light detecting signal to the other side, continue to detect the visible light signal of whether receiving high frequency afterwards, set up till optical communication is connected until described first subscriber equipment and described second subscriber equipment;
Wherein, for fear of described first subscriber equipment and described second subscriber equipment conflicting on operation is carried out, that is: execution detection and/or transmission visible light detecting signal clash, after the subscriber equipment of receiving the visible light detecting signal can be set determine that the check code of visible light detecting signal is correct, postpone the T2 duration earlier, send the responsive to visible light signal to the subscriber equipment that sends the visible light detecting signal more afterwards; Wherein, more than 2 times of duration of the duration of the T2 visible light detecting signal that is set to send; Simultaneously, detection for fear of described first subscriber equipment and described second subscriber equipment clashes in time, the duration of the assay intervals T1 of the duration of the assay intervals T1 of described first subscriber equipment and described second subscriber equipment is inequality, therefore, the duration that T1 can be set is a period of time at random, and value meets the rule of Poisson random probability distribution, simultaneously, in order to save energy consumption, the duration that T1 can be set is far longer than the duration of the visible light detecting signal of transmission;
When practical application, can on described first subscriber equipment and described second subscriber equipment, set up the visible light communication module respectively, be used to set up optical communication and connect the line data transmission of going forward side by side, the visible light communication module comprises emitter and photosensitive device; Wherein, emitter is used for the visible emitting detectable signal, and the signal that will send data is modulated on the visible light, the visible light signal of emission modulation afterwards, photosensitive device is used to receive the visible light detecting signal, and the visible light signal of reception modulation, extract high-frequency signal from the visible light signal of modulation, that is: data-signal recovers the data that the other side sends; Wherein, in order to improve data transmission bauds, emitter is set launches the visible light of two or more colors, such as: green and blueness etc., when setting up the optical communication connection, the visible light that the visible light detecting signal is a kind of color is set, the responsive to visible light signal is the visible light of another kind of color, the both sides that communicate determine self to send the color of the visible light signal of data in view of the above, thereby improve message transmission rate;
Here, described first subscriber equipment specifically can be portable sets such as mobile phone, portable media player (PMP, Portable Media Player) or small size net book, also can be non-portable sets such as desktop computer; Accordingly, described second subscriber equipment specifically can be portable sets such as mobile phone, PMP or small size net book, also can be non-portable sets such as desktop computer.
Step 201: described first subscriber equipment and described second subscriber equipment carry out transfer of data by the visible light signal of modulation;
Particularly, the data signal modulation that data receiver will need to send is to visible light, and the visible light signal with modulation sends to the data receiver afterwards; After the data receiver receives visible light signal, from the visible light signal of modulation, extract high-frequency signal, recover the data that data receiver sends;
Wherein, when modulation signal, the visible light signal that data-signal is a high frequency can be set in advance;
With data signal modulation to the visible light concrete processing procedure and prior art in the concrete processing procedure of modulating identical, repeat no more here; Same, the concrete processing procedure and the existing processing procedure that extract high-frequency signal from the visible light signal of modulation, recover the data that data receiver sends are identical, also repeat no more here;
When practical application, the set-up mode of emitter and photosensitive device can be: emitter and photosensitive device all adopt embedded mode, under this set-up mode, the signal that sends data is modulated in the brightness of screen background light of portable set, thereby launch, if self has photosensitive device portable set, first-class such as shooting, then directly adopt the photosensitive device of self to receive the visible light signal that the other side's irradiation is come, and the high-frequency signal of extraction visible light signal, recover the data that the other side sends, if portable set self does not have photosensitive device, first-class such as shooting, then can increase a light-sensitive device as photosensitive device,, adopt the light-sensitive device that increases to receive the visible light signal that the other side's irradiation is come such as phototriode, and the high-frequency signal of extraction visible light signal, recover the data that the other side sends;
The set-up mode of emitter and photosensitive device can also be: emitter adopts embedded mode, photosensitive device adopts external mode, such as mode by the USB plug-in card, under this set-up mode, the process of transmission data and receiving course and emitter and photosensitive device all adopt the concrete processing procedure of embedded mode identical, repeat no more here;
The set-up mode of emitter and photosensitive device can also be: emitter and photosensitive device all adopt external mode, mode such as the USB plug-in card, under this set-up mode, can adopt low power colorful light-emitting diode (LED, Light Emitting Diode) as emitter, simultaneously, adopt the sensor devices of the color sensitivity that LED is sent as photosensitive device;
In data transmission procedure, according to the intensity of the visible light signal of receiving, adjust the size of drive current, so that reduce the power consumption of portable set; Wherein, after photosensitive device is received visible light signal, can detect the intensity of visible light signal, adjust the size of drive current in view of the above; The concrete processing procedure of adjusting the drive current size is identical with existing processing procedure, repeats no more here;
In the process of transfer of data, described first subscriber equipment and/or described second subscriber equipment are reminded the user in the mode that sound and/or literal show, two subscriber equipmenies are close, so that save power consumption, and improve transmission rate; Particularly, the minimum current value that can receive signal can be set,, then remind the user that two subscriber equipmenies are close as long as current value is not the minimum current value; Wherein, when the minimum current value is set, be provided with according to the performance of the employed subscriber equipment of user;
In the process of transfer of data, after if the data receiver finds the equal mistake of verification of N packet that receive, continuous, then show in the process of transfer of data and fault occurred, at this moment, the data receiver can resend the visible light detecting signal, again set up optical communication with data receiver and be connected, continue the transmission of data afterwards; Wherein, the method for checking data bag can adopt existing arbitrary method of calibration, such as CRC method etc.; Two the sending out of communication can be arranged the method that the checking data bag is adopted in advance; When the N value is set, according to the experimental result setting, such as: in the process that experimentizes, when breaking down, the verification of 3 that receive, continuous above packets all can mistake, and therefore N can be set is 3; The reason that breaks down is: data receiver causes the data receiver can't correctly recover the data that data receiver sends because the situation of shutting down has appearred in power shortage, and perhaps, the visible light signal that data receiver sends has been blocked.
After transfer of data was finished, data receiver was finished by visible light signal notification data recipient transmission, after the data receiver is notified, disconnected optical communication with data receiver and was connected; Wherein, the concrete processing procedure of finishing by visible light signal notification data recipient transmission and the processing procedure of transfer of data are identical, repeat no more here.
Below in conjunction with embodiment the present invention is described in further detail again.
In the present embodiment, the emitter of first subscriber equipment and second subscriber equipment and photosensitive device all adopt external mode, and emitter can be launched blue light and two kinds of visible lights of green glow, the data transmission method between the subscriber equipment of present embodiment, as shown in Figure 3, may further comprise the steps:
Step 301: when needing the transmission data, first subscriber equipment and the every interval of second subscriber equipment T1 duration at random, the visible light signal of detection high frequency, execution in step 302 afterwards;
Here, the visible light signal of described high frequency just is meant the visible light detecting signal;
The duration of the assay intervals T1 of the duration of the assay intervals T1 of described first subscriber equipment and described second subscriber equipment is inequality, and the value of T1 meets the rule of Poisson random probability distribution.
Step 302: the subscriber equipment of receiving the visible light detecting signal judges whether the check code of visible light detecting signal correct, determine correct after, execution in step 303, otherwise, execution in step 304.
Step 303: send the responsive to visible light signal to the subscriber equipment that sends the visible light detecting signal, execution in step 305 afterwards;
Here, when the visible light detecting signal is blue light, the subscriber equipment of receiving the visible light detecting signal then adopts green glow to send the responsive to visible light signal to the subscriber equipment that sends the visible light detecting signal, when the visible light detecting signal is green glow, receive that the subscriber equipment of visible light detecting signal then adopts blue light to send the responsive to visible light signal to the subscriber equipment that sends the visible light detecting signal;
After the subscriber equipment that sends the visible light detecting signal is received the responsive to visible light signal, show then that described first subscriber equipment is connected with the optical communication of described second subscriber equipment to set up;
Afterwards, when carrying out transfer of data, described first subscriber equipment adopts separately with described second subscriber equipment and sets up the light color transmission data of confirming when optical communication is connected; Give an example, if described first subscriber equipment adopts blue light to send the visible light detecting signal to described second subscriber equipment, described second subscriber equipment adopts green glow to send the responsive to visible light signal to described first subscriber equipment, then when transfer of data, described first subscriber equipment adopts blue light to the described second user device transmissions data, and described second subscriber equipment adopts green glow to the described first user device transmissions data; If described first subscriber equipment adopts green glow to send the visible light detecting signal to described second subscriber equipment, described second subscriber equipment adopts blue light to send the responsive to visible light signal to described first subscriber equipment, then when transfer of data, described first subscriber equipment adopts green glow to the described second user device transmissions data, and described second subscriber equipment adopts blue light to the described first user device transmissions data.
Step 304: after receiving the subscriber equipment delay T2 duration of visible light detecting signal, the visible light detecting signal to the other side sends the T3 duration re-executes step 301 afterwards;
Here, in order to save energy consumption, the duration that T1 is set is far longer than T2;
When practical application, determine the duration of T3 according to the operating frequency of the length of the visible light detecting signal of subscriber equipment and subscriber equipment; Wherein, the length of visible light detecting signal that transmission generally can be set is between 20～30 bits, and therefore, the operating frequency of subscriber equipment is high more, and then the value of T3 is more little;
When sending the visible light detecting signal,, therefore, can be provided with and adopt blue light and green glow alternately to send the visible light detecting signal, till the responsive to visible light signal of receiving the other side because emitter can be launched blue light and green glow.
Step 305: the data signal modulation that data receiver will need to send is to visible light, and the visible light signal with modulation sends to the data receiver afterwards; After the data receiver receives visible light signal, extract high-frequency signal from the visible light signal of modulation, recover the data that data receiver sends, execution in step 306 afterwards;
Here, in data transmission procedure, described first subscriber equipment and/or described second subscriber equipment are adjusted the size of drive current according to the intensity of the visible light signal of receiving, so that reduce the power consumption of portable set;
In data transmission procedure, described first subscriber equipment and/or described second subscriber equipment with sound/or the mode that literal shows remind the user, two subscriber equipmenies are close so that save power consumption, and improve transmission rate;
In the process of transfer of data, after if the data receiver finds the equal mistake of verification of N packet that receive, continuous, the data receiver can resend the visible light detecting signal, sets up optical communication with data receiver again and is connected, and continues the transmission of data afterwards.
Step 306: after transfer of data was finished, data receiver was finished by visible light signal notification data recipient transmission, after the data receiver is notified, disconnected optical communication with data receiver and was connected, and finished current handling process.
Because method of the present invention needs radiation of visible light to the photosensitive device of portable set, just can receive the data that data receiver sends, in other words, if want to obtain the data that data receiver sends, must in the observable scope of user, just might receive the data that data receiver sends, so, can improve the fail safe of communication process, and then promote user experience.
