Embodiment Construction

[0043] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] The present invention provides a method of correcting signal distortion.

[0045] refer to figure 1 , figure 1 It is a schematic flowchart of an embodiment of a method for correcting signal distortion in the present invention.

[0046] A method for correcting signal distortion provided in this embodiment includes the following steps:

[0047] Step S10, scanning a test barcode with the same width as the bar space, and using the scanning width value obtained by scanning each bar space of the test barcode as the distortion width value;

[0048] First, control the laser barcode scanning platform to enter the setting state. At this time, the laser barcode scanning platform can only read the setting code with specific setting functions, and then the laser barcode scanning platform scans the setting code that contr...

Abstract

The invention discloses a method for correcting signal distortion. The method consists of the steps of: scanning a bar-space equal-width test barcode and using the scanned width value of each bar-space acquired by scanning the test barcode as a distortion width value; acquiring the average distortion width value of the bar-spaces of the test barcode according to the distortion width value of each bar-space of the test barcode; using the average distortion width value as the reference value to acquire the deviation value of the distortion width value and the average distortion width value and correcting the acquired scanning width value of the scanned barcode according to the deviation value. The invention also discloses a laser barcode scanning platform. By means of this invention, the distortion of the barcode signal transformed from a barcode width value is corrected, the code reading performance of the laser barcode scanning platform is enhanced, and it is not necessary to write control programs for the laser heads of each laser barcode scanning platform equipment; in the meantime, the requirements for laser head precision and manufacturing technique are lowered, and the production cost of laser barcode scanning platform is lowered.

Description

technical field [0001] The invention relates to the technical field of barcode scanning, in particular to a method for correcting signal distortion and a laser barcode scanning platform. Background technique [0002] At present, the barcode laser barcode scanning platform has been able to be mass-produced, but due to the lack of performance of the physical hardware itself (for example, the optical head), or the error caused by the process operation or manual operation in the production process, the grid light formed by the laser barcode scanning platform There is distortion in the signal data reflected by scanning the barcode. The distortion of this light is directional as a whole, that is, the distortion that is closer to the optical head and farther away from the optical head is infinite. That is to say, the distortion of this light It shows a change process from strong to weak, and then from weak to strong, but the distortion of the scanning light on each light point is r...
