Specific embodiment
With reference to the accompanying drawing, technical solution of the present invention is described in detail.
Above-mentioned two dimensional code is scanned using scanning device.As shown in figure 5, the scanning device of the embodiment of the present invention includes for mentioning
For the illumination chip 3 of light source, illumination chip 3 includes at least two chip units 301.Chip unit 301 is connected in parallel.The implementation
In example, chip unit 301 is multiple.It is in parallel between multiple chip units 301.In this way, even if one of chip unit 301 damages
It is bad, other chip units 301 normal work will not be influenced.And in the prior art, a chip unit 301 is usually only set.
When chip unit 301 damages, entire scanning device also be can not work normally.The present embodiment, by between chip unit 301 simultaneously
Connection connection, extends the service life of scanning device.
Further, as shown in fig. 6, the polar region P of the chip unit 301 is etched into semicircle or polygon.When the pole P
Area is etched into semicircle or polygon, can increase light extraction efficiency, so that the light that chip unit 301 issues is easier to scanning recognition
Two dimensional code.
Further, the chip unit 301 uses monochromatic source.When using monochromatic source, two dimensional code can for except
Other colors other than black.Chip unit 301 uses monochromatic light, and the color of corresponding two dimensional code is arbitrarily selected,
Improve user experience.The monochromatic source is semiconductor light-emitting-diode, light emitting diode with quantum dots or organic light emission two
Pole pipe.The semiconductor light-emitting-diode is polarity light emitting diode, semi-polarity light emitting diode or nonpolar light-emitting diodes
Pipe.
In the scanning device of above-described embodiment, using parallel way be arranged light source so that any chip unit 301 by
When damage, it is unlikely to, so that the loss of product substantially reduces, solve two-dimensional code scanning so that entire scanning device is scrapped
The shortcomings that equipment is easily damaged.
The scanning device of above-described embodiment obtains data information for scanning the two-dimensional code.As shown in Figure 1, the two dimensional code,
Array 2 is identified including matrix 1 and the two dimensional code being printed on matrix 1.Matrix 1 can be packaging bag, label, paper etc..Matrix 1
It is the carrier of two dimensional code identification array 2.Two dimensional code identifies that array 2 includes at least two two dimensional code recognition units 201, and two dimensional code is known
Angle between other unit 201 is a, 0 180 ° of < a <.The two dimensional code identification array 2 printed on matrix 1 includes multiple two dimensions
Code recognition unit 201, and the direction of multiple two dimensional code recognition units 201 is not same direction.
Existing two dimensional code only includes a two dimensional code recognition unit 201.When being scanned the two-dimensional code using scanning device,
Scanning port usually requires holding and the consistent direction of two dimensional code, could scan successfully.When direction is inconsistent, needs to adjust and sweep
The direction of port is retouched, or changes the direction of matrix 1, so that scanning port and two dimensional code recognition unit 201 are consistent.It is existing
In technology, need frequently to adjust the direction of scanning device or matrix 1, it could scanning recognition success.And in the present embodiment, due to
Two dimensional code identifies that array 2 includes at least two two dimensional code recognition units 201, and the direction of two dimensional code recognition unit 201 is inconsistent,
So the direction of scanning port is easy to consistent with the direction of two dimensional code recognition unit 201 or low-angle adjustment is swept in scanning
The direction for retouching port, the direction that scanning port can be realized are consistent with the direction of two dimensional code recognition unit 201.In this way, this implementation
Example does not need wide-angle or the frequently direction of adjustment scanning port, to realize direction and the two dimensional code recognition unit of scanning port
201 direction is consistent.
After realizing scanning, information is accurately obtained, in the two dimensional code recognition unit, between two dimensional code recognition unit 201
Without mutual overlapping region.In this way, information can be obtained using any one two dimensional code recognition unit 201 of scanning device scanning.
Two dimensional code recognition unit 201 is placed with diversified forms in two dimensional code identification array 2.Four kinds of structure type conducts are tightly enumerated below
Example.
The first structure type, as shown in Figure 1, two dimensional code identification array 2 includes two two dimensional code recognition units 201, and
Angle between two two dimensional code recognition units 201 is 90 °.In the structure type, it is equivalent to and is respectively set horizontal and vertical
Two dimensional code recognition unit 201.As long as scanning device is directed at one of them and is scanned, acquisition information can be realized.In transverse direction
It is respectively provided with two dimensional code recognition unit 201 with longitudinal, the scanning port of scanning device does not need to be rotated by 90 °, can be realized and sweep
One of two dimensional code recognition unit 201 is retouched, rotation angle is reduced, is conducive to improve scan efficiency.Certainly, those skilled in the art
Member should know that 90 ° are only illustrated.It can also be the other angles such as 60 °, 80 °.
Second of structure type, as shown in Fig. 2, two dimensional code identification array 2 includes three two dimensional code recognition units
201, the angle between two neighboring two dimensional code recognition unit 201 is 60 °.Three two dimensional code recognition units 201 can be with positive three
Angular shape is laid.Three two dimensional code recognition units 201 are set, the rotation angle of scanning device can be further reduced, made
The scanning port direction and one of 201 direction of two dimensional code recognition unit for obtaining scanning device are consistent.Compare the first knot
The two dimensional code of configuration formula, this example identifies in array 2 that the rotation angle of scanning device is smaller, further increases scan efficiency.
The third structure type, as shown in figure 3, two dimensional code identification array 2 includes four two dimensional code recognition units
201, the angle between two neighboring two dimensional code recognition unit 201 is 90 °, and upper and lower two two dimensional code recognition units 201 are opposite,
The two dimensional code recognition unit 201 of left and right two is opposite.After four two dimensional code recognition units 201 are laid, a square is formed.Namely
It says, laterally lays two, longitudinal also laying two.When the scanning port of scanning device scans two dimensional code identification array 2, only
Want scanning port direction consistent with any one 201 direction of two dimensional code recognition unit.Compared with the first structure type, this
Increase the two dimension of the two dimensional code recognition unit 201 and a longitudinal direction that are provided with a transverse direction in the two dimensional code identification array 2 of example
Code recognition unit 201.This makes scanning device be easier to scan the two-dimensional code identification array 2.

Angle is a, 0 180 ° of < a <.This make scanning device scanning port and two dimensional code recognition unit 201 closer to, it is easier to sweep
It retouches.
The embodiment of the present invention also provides a kind of scanning system, including two dimensional code and scanning device.Scanning device is for scanning
Two dimensional code obtains information data.Two dimensional code uses the two dimensional code of above-described embodiment.Specifically, two dimensional code includes matrix 1 and print
It makes the two dimensional code on matrix 1 and identifies array 2, the two dimensional code identification array 2 includes at least two two dimensional code recognition units
201, the angle between two dimensional code recognition unit 201 is a, 0 180 ° of < a <.Scanning device is set using the scanning of above-described embodiment
It is standby.Specifically, scanning device includes for providing the illumination chip 3 of light source, and illumination chip 3 includes at least two chip units
301, the chip unit 301 is connected in parallel.Preferably, the polar region P of the chip unit 301 is etched into semicircle or polygon
