Abstract

The invention relates to the production management for a high-frequency straight seam welded pipeline, in particular to a real-time information management method and a real-time information management system for a production line of a high-frequency straight seam welded pipe. The system comprises a PLC system, a main database of steel pipe information, an upper volume database, and two low-layer basic databases; and the system uses two steel plate continuous length measurement devices to accurately measure the length of band steel entering a main frame production line and the length of a cut part of a steel pipe after the band steel is processed into the steel pipe, thereby realizing the record storage and utilization of production information of the steel pipe. The information system comprises raw material information, upper volume information, accurate information of the length of the band steel, edge milling information, steel plate defect information, molding information, welding information, welding seam defect information, heating information, stenciling information, accurate information of the length of the steel pipe, cutting information, dimension-changing information, test information, chamfering information, detection information, measurement information, test information, stenciling information, and warehouse entry information. The system can straighten out data formed by various devices of the production line, and has accurate information, large utilization value of the information, and development value.

Description

technical field [0001] The invention relates to the structure of information in the production process of the high-frequency straight seam welded pipeline production management system, the generation method and utilization of basic information, especially a real-time information management method and system for the high-frequency straight seam welded pipe production line. Background technique [0002] At present, the large-diameter high-frequency longitudinal welded pipe production line is in a stage of rapid development, and the production equipment can meet the needs of production, but the real-time production management system is still in its infancy. Most of the production equipment generates production information in the form of a single machine independently, and there is no system. The production management system cannot provide timely and sufficient production process information, and cannot meet the needs of the superior management department or meet the management n...
