Abstract

Embodiments of the present invention provide a graphic code scanning method, device, and scanning gun, wherein the method is applied to a processor in the scanning gun, and the scanning gun also includes a sensor, an alignment light source, and a reflection light source. The method includes : When the alignment light source and reflection light source are turned on, judge whether there is a pattern code to be scanned in the alignment area; if there is a pattern code to be scanned in the alignment area, judge whether the sensor is in the sensing state; if the sensor is in the sensing state , turn off the alignment light source; receive the reflected light signal sensed by the sensor, and determine the information corresponding to the pattern code to be scanned according to the reflected light signal. The technical solution of the embodiment of the present invention can reduce the light signal error of the reflected light source reflected by the graphic code received by the sensor, and improve the scanning accuracy of the scanning gun.

Description

technical field [0001] The invention relates to the technical field of graphic code scanning, in particular to a graphic code scanning method, device and scanning gun. Background technique [0002] The scanning gun can read the price, name, item number and other information of the product by scanning the graphic code of the product, and scan the graphic code optically, which can quickly read and judge the data, saving management and personnel costs. The graphic code mentioned above may be, for example, a barcode or a two-dimensional code. [0003] When the existing scanning gun scans the graphic code, the method usually used is: the aiming light source of the scanning gun emits the aiming light, and the operator aligns the graphic code to be scanned with the scanning gun according to the aiming light, and at the same time the scanning gun The reflected light source irradiates the graphic code to be scanned, and the graphic code to be scanned reflects the received light of t...
