Embodiment
As shown in Figure 1, a kind of data transmission system based on photoflash lamp in mobile phone and photoelectric probe, comprise mobile phone part 1 and tcp data segment 2, described tcp data segment comprises camera 4, LED photoflash lamp 3 and photoelectricity receiving transducer 5, and described photoelectricity receiving transducer 5 is placed on LED photoflash lamp 3 and near 4 positions of shooting.LED photoflash lamp 3, as optical transmitting set, is modulated and data transmission the light signal of LED photoflash lamp; Photoelectricity receiving transducer 5, as receiver, is accepted the light signal that LED photoflash lamp 3 sends, and is translated into the signal of telecommunication.The array architecture that described LED photoflash lamp 3 is comprised of a white LED lamp 6 or a plurality of white LED lamp 6; The array architecture that described photoelectricity receiving transducer 5 is comprised of a PIN photodiode 7 or a plurality of PIN photodiode 7.
Between common mobile phone, utilize electromagnetic transmission signal, realize transfer of data.The transmission of visible light signal that the present invention utilizes mobile phone camera photoflash lamp to send, then by PIN photodiode 7 receiving optical signals, then carries out data processing, realizes between mobile phone closely transfer of data.
System of the present invention comprises conventional mobile phone part and high speed data transfer part.Conventional mobile phone partly needs for common communication, such as mobile phone short message etc.High-speed transfer partly comprises camera, LED photoflash lamp and the receiving unit being comprised of PIN photodiode.Conventionally mobile phone camera camera and LED photoflash lamp are adjacent getting together, in system of the present invention, high speed optoelectronic receiving transducer 5(PIN photodiode) be placed near position LED photoflash lamp 3 and camera 4.
The white light that the LED photoflash lamp 3 of mobile phone camera sends is visible ray, generally synthetic by three coloured light, wavelength conventionally at 380nm between 780nm.LED white light technical development is at present rapid, and aspect raising transmitting power, progress is not little, is conducive to it as communication light source.
LED light source has luminous intensity and two parameters of luminous power, the white light that LED photoflash lamp 3 sends not only can throw light on for mobile phone camera when taking pictures and make a video recording, and can be used as signal source, for short-distance wireless transfer of data, the LED photoflash lamp 3 that uses mobile phone camera to carry, just kills two birds with one stone.And white LED lamp 6 also has low in energy consumption, long service life, the advantage such as size is little, environmental protection.
As shown in Figure 2, between mobile phone, closely during transfer of data, LED photoflash lamp 3 is used as signal optical source, and the information exchanges such as phonetic image are crossed data processing and changed the signal of telecommunication into, are then all modulated to above LED photoflash lamp 3, finally transmitting outward.LED photoflash lamp 3 during as signal optical source, need to apply bias current to it.
As shown in Figure 3, single white LED lamp 6 luminous powers and luminous intensity are limited, in order to increase luminous intensity and luminous power, can also adopt a plurality of white LED lamps 6, form array, the present invention adopts 9 white LED lamps 6 to form array, can increase greatly like this value of light signal, can be transferred to place far away, increase communication distance.
The size of message transmission rate is subject to the impact of LED modulation bandwidth.Modulation bandwidth is the parameter of weighing LED modulation capability, is related to the size of LED light source message transmission rate in wireless light communication.From the principle, two factors that affect LED high-speed transfer speed are: carrier lifetime and junction capacitance.Therefore from LED design and production technology, improve this two factors, also can improve message transmission rate.Have again by appropriate design and optimize white LED lamp 6 drive circuits, also can improve transmission rate.
But by optimizing LED design and LED drive circuit, the transmission rate of raising is limited after all, so the present invention considers to adopt other mode, realizes high speed data transfer.Because white LED lamp 6 is to be composited by three coloured light, be that the monochromatic light by three different wave lengths of RGB is composited, therefore adopt wavelength division multiplexing (WDM) technology, three coloured light are modulated respectively.Conventionally the modulation bandwidth of white LED lamp 6 only has 3～50M hertz, adopts wavelength-division multiplex technique, and transmission rate can realize the growth of several times to tens times, thereby realizes high-speed transfer.
When the present invention carries out point-to-point communication, the light signal of the band modulation of sending from the LED photoflash lamp 3 of side's mobile phone camera, transfers to the opposing party, by the opposing party's mobile phone with high speed PIN photodiode 7 receive, change light signal into the signal of telecommunication, then carry out data processing, realize communication between the two.
Therefore system of the present invention, on traditional mobile phone basis, increases high speed PIN photodiode 7 as receiver, the white light signal of sending for receiving LED photoflash lamp 3.
In system, in order to realize high speed data transfer, adopted wavelength-division multiplex technique, the three coloured light signals that send in order to receive white LED lamp 6, high speed PIN photodiode 7 need to add respectively three-colour filter, could realize wavelength division multiplexing.As shown in Figure 5, signal receiving circuit partly comprises PIN photodiode 7 and preamplifier, limiting amplifier, output buffer and signal deteching circuit.
The major parameter of PIN photodiode 7 comprises sensitivity and responsiveness.Sensitirity va1ue is less, and the light signal that expression can receive is more weak.Responsiveness is the ability of the signal of telecommunication that light signal is changed into, and responsiveness is higher, and transformation ability is stronger.When therefore the present invention selects, can select Sensitirity va1ue less, the PIN photodiode 7 that responsiveness is higher.So that can use in place relatively far away system of the present invention to realize point-to-point data in mobile phone transmission.
Use the present invention except carrying out between mobile phone closely high-speed data communications, people have been met greatly by the needs of mutual transfer files between mobile phone, can also meet people there is no the space of mobile phone electromagnetic wave signal or using the limited place of electromagnetic communication, realize the closely needs of speech data communication.
Should be appreciated that specific embodiment described above, only for explaining the present invention, is not intended to limit the present invention.The apparent variation of being extended out by spirit of the present invention or change are still among protection scope of the present invention.
