Abstract: According to the plate production process and analysis of domestic actualities, the whole process tracking for the plate production line is divided into three parts: position micro-tracking, process tracking and material tracking, with a consolidated scheme determined to implement the tracking procedure. The position micro-tracking is put into effect by the basic automation system to provide the key tracking information, the process tracking and material tracking both depend on the process control system. With the data flow designed for the whole process tracking, a central database is set up for tracking data storage/transfer. Then, the material tracking is implemented according to the operation of data sheet. The whole process tracking proposed here has been applied successfully in several domestic plate production lines.
