Embodiment 1
[0029] Such as figure 1 As shown, this embodiment provides a code scanning method, which is applied to a code scanning device. The code scanning device includes at least a first light source and a second light source. The colors of the first light source and the second light source are different. The code scanning method include:
[0030] Step S101: When the code scanning device is triggered to scan the current time, control the first light source to emit light, and obtain the first code scanning result of scanning the first graphic code.
[0031] It should be noted that the first graphic code may be an identification coded by color blocks of different colors, such as a barcode or a two-dimensional code.
[0032] Step S102: Determine whether the first code scanning result satisfies a preset condition.
[0033] Step S103: If not, switch to the second light source to emit light, and obtain a second code scanning result of scanning the first graphic code.
[0034] As we all kn...
Embodiment 2
[0073] Such as figure 2 As shown, this embodiment provides a code scanning device, including:
[0074] The first light source 1 and the second light source 2, the colors of the first light source 1 and the second light source 2 are different;
[0075] The controller 3 is connected with the first light source 1 and the second light source 2, and is used to control the first light source 1 to emit light when the code scanning device is triggered to perform the current scan, and to obtain the first scan code for scanning the first graphic code. code result, judge whether the first code scanning result satisfies the preset condition; if not, switch to the second light source 2 to emit light, and obtain the second code scanning result of scanning the first graphic code.
[0076] As we all know, objects of different colors reflect differently to various light components in the same light source. Since the different light components reflected back have different intensities and ene...

Abstract
The invention discloses a code scanning method and code scanning equipment. The code scanning method is applied to the code scanning equipment, and the code scanning equipment at least comprises a first light source and a second light source, wherein the colors of the first light source and the second light source are different. The code scanning method comprises the following steps: controlling the first light source to emit light, obtaining a first code scanning result for scanning the first graphic code; judging whether the first code scanning result meets a preset condition or not; if not,switching to the second light source to emit light, and obtaining a second code scanning result for scanning the first graphic code. During code scanning, the first light source is used for scanning,when scanning fails, the first light source is switched to the second light source, the light source suitable for current scanning and capable of achieving correct reading of the first graphic code is found in a light source switching mode, and the problem that in the prior art, when code scanning equipment faces various bar codes, code scanning failure is liable to occur is solved.
Description
technical field [0001] The present invention relates to the technical field of code scanning, in particular to a code scanning method and a code scanning device. Background technique [0002] In recent years, with the continuous improvement of my country's informatization level, the application of barcodes has become more and more extensive. Logistics, retail, medical, warehousing, manufacturing and other industries have begun to use barcodes for traceability and management, which can greatly improve production and work. efficiency. A barcode is a graphic identifier used to carry numbers and letters. It is composed of color blocks of different widths and reflectivity. These color blocks of different colors and widths can express different information according to specific coding rules. [0003] As we all know, different colors have different reflectivity, for example: black bars and white background barcodes, black absorbs all colors of light components in light, and white r...
