Bar code reading device and reading method thereof

Abstract

The invention discloses a bar code reading device, which relates to the technical field of bar code scanning devices, and comprises a shell, a trigger, a main board which is arranged in the shell andis provided with a central processing chip, a bar code scanning module and a photosensitive device which are connected with the main board, and a brightness sensing module which is connected with thetrigger and the main board, the lighting module is connected with the main board and the brightness sensing module; the bar code scanning module is a camera module, and the photosensitive device captures an image of a bar code. The invention further comprises a reading method. The reading method comprises the following steps: a brightness sensing step; an illumination adjusting step; decoding step. According to the invention, the brightness sensing module is arranged to sense the brightness of the surrounding environment of the bar code reading device. According to the brightness degree, the illumination module is automatically adjusted to the effective brightness so as to help the bar code scanning module to scan the bar code; bar code scanning in a dark environment can be achieved; meanwhile, light can be provided for sorters; sorting work of the sorters is facilitated; and the effect of improving the working efficiency is achieved.

Description

technical field [0001] The present invention relates to the technical field of barcode scanning devices, more specifically, it relates to a barcode reading device and a reading method thereof. Background technique [0002] With the rapid development of the national economy, China's logistics industry has maintained a rapid growth rate, and the logistics system has been continuously improved. In logistics management, it is usually necessary to distinguish different goods. Generally, barcodes are pasted on different goods to generate relevant information unique to the goods, and the equipment for reading barcodes is a barcode reading device. [0003] When logistics sorting works outdoors, when the sorter enters the dark state and the work is not completed, the sorter still needs to continue working in the dark environment to complete the sorting. At this time, the existing barcode reading device is either difficult to operate Barcode reading in a dark environment, or using in...

Problems solved by technology

[0003] When logistics sorting works outdoors, when the sorter enters the dark state and the work is not completed, the sorter still needs to continue working in the dark environment to complete the sorting. At this time, the existing barcode reading device is either difficult to operate Barcode reading in a dark environment, or using infrared sensing to read barcodes in a dark environment, but because of the darkness of the surrounding environment, it still brings great inconvenience to the sorting work of the sorter, and the sorting Difficult for staff to work with lighting and barcode reader at the same time
