Description
Technical field
The present invention relates to technical field of visible light communication, a kind of visible ray based on APP identification striations code leads to
Communication system and using method thereof.
Background technology
White light LEDs have energy-conservation, reliable, life-span length, price are low and the characteristic such as High Speed Modulation, can realize simultaneously illumination and
Visible light communication dual-use function.Visible light communication has energy-saving safe, exempts from electromagnetic interference, traffic rate height and be accurately positioned
A lot of advantages, have a extensive future, are the study hotspots of optical communication field.From Japanese researchers in 2000, visible light communication is proposed
Rising, through the development of more than ten years, transfer rate is more and more higher, constantly making a breakthrough property achievement.
Pixel on most of cmos sensors is triggered successively by horizontal scanning line, therefore can not immediately obtained complete figure
Picture.During triggering, horizontal scanning line exposes successively, samples and stores.After this process completes, scan line will combine with
Forming the image that a width is complete, Rolling shutter is exactly the term describing this process.
Cmos sensor is used for visible light communication receiving terminal, is beneficial to the promotion and application of visible light communication technology.
The Rolling shutter using CMOS carries out visible light communication, can receive the imperceptible flicker information of human eye, according to receive
Bright dark fringe is decoded, and utilizes this effect can realize the data rate far above cmos sensor frame frequency.
To LED illumination lamp, make the alternately luminescence of its light and shade by coding chip, produce light and shade stripe pattern.Coding chip
Coded system is that every frame includes initial bits and information bit, and initial bits is made up of 4bit " 1 " continuously, it is stipulated that information bit
First place is " 1 ", and position, end is " 0 ", then after Manchester's code, data become " 111101 ... 101111 "；Coded data is
1, then illumination lamp ignition, coded data is 0, then illuminating lamp extinguishes, and thus produces light and shade stripe pattern；Connect by cmos sensor again
Receive and identify such light and shade stripe pattern, then by specific program, light and shade stripe pattern is resolved, then can obtain light and shade striped
The information loaded in image, completes the process of visible light communication.
Summary of the invention
The purpose of the present invention, be to provide for a kind of efficient, energy-conservation, a kind of based on APP identify striations code can
See optical communication system.Native system, can be applicable to various information exchanging system, such as introduction system, the market of museum exhibits information
Article purchase guiding system, logistics warehouse inventory management system, smart city street lamp information exchanging system etc..
For achieving the above object, the present invention adopts the following technical scheme that
1, the system of the present invention includes: transmitting terminal module, receiving terminal module, signal processing module.Described transmitting terminal module
For the lighting of Embeded coding chip, produce the light and dark stripe pattern that human eye cannot be discovered；Described receiving terminal module
For the electronic product with COMS sensitive component, detect the light and dark stripe pattern that described transmitting terminal produces；Described letter
Number processing module is the APP program of described system, is installed in receiving terminal module, and described receiving terminal detected is light and dark
Stripe pattern be decoded, and call related content according to information therein, be presented in described receiving terminal module.
2, the LED illumination lamp that lighting is Embeded coding chip in described transmitting terminal module, Embeded coding chip
For single-chip microcomputer or PLD.
3, the COMS sensitive component in described receiving terminal module requires that pixel number, higher than 1280 × 720 pixels, divides
Resolution is higher than 200W pixel, and frame frequency is higher than 30fps.
It is an advantage of the current invention that can directly utilize lighting carries out the realization of visible light communication, only need to drive
Increase coding chip in device, and replace without making whole lamp, therefore can reach cost-effective purpose.And control illuminating lamp and produced
Light and dark stripe pattern can not be detected by human eye, therefore have no effect on illuminating lamp and play the internal action of illumination.
Meanwhile, use the electronic product with COMS sensitive component directly to scan the light that illuminating lamp sends, or scanning illuminating lamp exists
Arbitrary objects surface emitting light, all can obtain the light and dark stripe pattern produced, and then obtain associated address information, make
With convenient.
Accompanying drawing explanation
Fig. 1 is that the system of the present invention constitutes block diagram.
Fig. 2 is the operation principle block diagram of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, i.e. use the museum exhibits letter of the information issuing system of APP identification striations code
The invention will be further described for breath explanation embodiment, only explains this by the schematic description and description of the present invention at this
Invention, but not as a limitation of the invention.
According to Fig. 1, this system is made up of transmitting terminal module, receiving terminal module, signal processing module.It is being embodied as
In example, transmitting terminal is the museum lighting lamp of Embeded coding chip；Receiving terminal is smart mobile phone；APP program can download installation
Being applied on smart mobile phone, and showpiece explanation resources bank is packaged in APP, its content is provided previously by by museum.
First, the museum lighting lamp of Embeded coding chip is installed, as long as to existing natural science according to museum's site environment
The drive circuit of shop illuminating lamp is simply transformed and can be completed.
Secondly, the information issuing system APP software based on striations code identification woven and explanation resource are published to
On relevant platform, download for visitor and install and use.
Finally, as in figure 2 it is shown, visitor uses the APP software downloaded, the photographic head of APP software transfer smart mobile phone is made
