Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0044] In order to reduce the error of the light intensity of the reflected light source reflected by the graphic code received by the sensor, thereby improving the scanning accuracy of the scanning gun, the embodiment of the present invention provides a graphic code scanning method, device and scanning gun. When the sensor is in the Turn off the alignment light source in the sensing state to prevent the reflected light signal sensed by the sensor from being af...

Abstract

Embodiments of the present invention provide a graphic code scanning method and device, and a scanning gun. The method is applied to a processor in the scanning gun. The scanning gun further includesa sensor, an alignment light source, and a reflective light source. The method includes: determining whether there is a graphic code to be scanned in an alignment area when the alignment light sourceand the reflective light source are in an on state; determining whether the sensor is in a sensing state if there is the graphic code to be scanned in the alignment area; turning off the alignment light source if the sensor is in the sensing state; and receiving a reflective light signal sensed by the sensor, and determining information corresponding to the graphic code to be scanned according tothe reflective light signal. According to the technical scheme, an optical signal error of the reflected light source reflected by the graphic code received by the sensor is reduced, and the scanningaccuracy of the scanning gun is improved.

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...
