Strip steel hot galvanizing production process data high-speed acquisition method

A strip steel hot galvanizing production process data high-speed acquisition method includes the following steps: first a strip steel hot galvanizing production process data acquisition value range is set, then a PLC stores a process value acquired in each cycle period in a DB having a fixed format in a fixed sequence, when a set number is reached, in a PLC program, a system function block SFB37 is called to actively send data block data to WinCC, in WinCC a corresponding DLL is called to disassemble data, and the data are stored to an SQL database in a time sequence. At the same time, human-computer interface programming is performed in WinCC and acquired data are displayed. The s trip steel hot galvanizing production process data high-speed acquisition method provided by the invention is realized under existing basic software and hardware conditions of a hot galvanizing production line. The highest configuration can be 1ms acquisition period according to the need. Real-time control curve display is provided, and the acquired data are archived and stored in the SQL database for on-line monitoring and historical data analysis by production technicians, thereby providing technical support for improving strip steel hot galvanizing quality.
