Description

Automatic system and method for dynamic identification and pay into the treasury of two-dimensional codes of cast pipe end face Technical Field The invention relates to the technical field of industrial automation, in particular to a system and a method for dynamically identifying and pay into the treasury-automatically manufacturing two-dimensional codes on the end face of a cast tube. Background In the cast tube large-scale production process, pay into the treasury is a key node for connecting production and storage, and directly influences the accuracy and efficiency of subsequent storage, delivery and production ledger statistics. At present, an AGV trolley is generally adopted in the industry as core equipment for cast tube transportation, but the existing pay into the treasury flow has the following technical defects: first, the existing process relies on manual inquiry and selection of the number of the pipe to be pay into the treasury cast from a Manufacturing Execution System (MES), and manually printing pay into the treasury sheets and then associating with the cast on the AGV trolley. The problems of wrong selection, missed selection, repeated check and the like of the pipe numbers easily occur in manual operation, so that pay into the treasury single information is inconsistent with actual cast pipe information, further the linkage problems of disordered warehouse entry, wrong warehouse entry and the like are caused, and the smoothness of the production flow is seriously influenced. Secondly, the two-dimensional code of cast tube terminal surface has the characteristics that the size is little (regular 12mm x 12 mm), module density is high (minimum module is only 0.38 mm), and AGV dolly is in continuous moving state (speed 0.3m/s-1.0 m/s) in the transportation, and cast tube specification span is big (DN 300mm-DN1000 mm) in addition, and the terminal surface position difference of different specification cast tubes is showing. The existing recognition scheme is difficult to cope with the complex scene, the recognition range of the fixed code reader is limited, only a single or a small number of cast pipes with different specifications can be covered, full-specification coverage cannot be realized, the handheld code reader needs manual operation after an AGV car is stopped, the transportation efficiency is reduced, the recognition stability in a moving state is poor, meanwhile, a special algorithm is not designed aiming at a moving target in the existing recognition technology, the problem of two-dimensional code image blurring caused by the movement of the AGV car is outstanding, and the decoding success rate is low. Thirdly, the existing scheme only relies on two-dimension code recognition results to count the number of cast pipes, and once two-dimension code misreading, misreading or manual operation errors occur, the number deviation cannot be found timely, so that the error risk of pay into the treasury information is further aggravated. Along with the continuous improvement of the requirements of intelligent manufacturing on automation, informatization and precision of production processes, the existing cast tube pay into the treasury identification mode which depends on manual intervention and has limited identification capability and lacks a verification mechanism cannot meet the actual requirements of cast tube manufacturers, and an integrated solution capable of realizing full-specification coverage, high-accuracy identification, automatic verification and bill generation in a moving state is needed.
