Full-frame decoding fixed industrial code reader based on redundancy scheduling

Abstract

The invention provides a full-frame decoding fixed industrial code reader based on redundancy scheduling. The industrial code reader comprises an image acquisition unit, a parallel processing unit and a logic processing unit; wherein the image acquisition unit is used for acquiring bar code images; the parallel processing unit comprises a plurality of processing subunits, the plurality of processing subunits are independently arranged, and the plurality of processing subunits simultaneously process the received bar code images; the input end of the logic processing unit is connected with the output end of the image acquisition unit so as to receive a bar code image, and the output end of the logic processing unit is connected with the input ends of the plurality of processing subunits so as to transmit the bar code image to each processing subunit when each processing subunit is in an idle state; the input end of the logic processing unit is connected with the output ends of the plurality of processing subunits so as to receive the decoding information, and bar code information is obtained through processing according to the received decoding information.

Description

technical field [0001] The invention relates to the technical field of barcode reading, in particular to a redundant scheduling-based full-frame decoding fixed industrial code reader. Background technique [0002] With the popularization of social informatization and the advancement of image recognition technology, the development of related fields such as industrial vision has been promoted, one of which is the automatic recognition technology of barcodes. Automatic identification technology refers to the automatic reading of relevant data of nearby target objects without human intervention through a certain identification device. Barcode technology provides an effective means for automatic, fast and accurate data collection and input, and solves the problem of slow manual input. In recent years, it has been widely used in various occasions, including supermarkets, retail stores, logistics centers, and industrial production lines. [0003] In the automatic barcode recognit...

Problems solved by technology

In the single-core processing method, shooting and decoding are carried out alternately. Due to the long decoding time, the barcode is out of view when the next shooting is performed. In the dual-core processing method, one core is responsible for continuous shooting, and the other core is responsible for decoding. Long, within a limited time, it is impossible to decode all the captured images, and both single-core and dual-core processing methods may not be able to decode images with barcodes, and decoded images may not have barcodes, and the decoding rate and stability cannot be guaranteed.
