【Abstract】 To meet the requirement of the reconstruction and development of rolling cut machine, a new architecture of control system of rolling machine is presented based on finishing analysis of its control theory and arithmetic. We use SoftSERCANS card in the computer as the interface between the control software and the executive component. So the main control function of system can achieve through the software. The software is programmed with VC in Windows NT embedded RTX, shared memory is created for communication between two processes, mutli thread is created for multi task. Experiments, show that the precision could be controlled within the range of ±0.5 mm when the speed of sending paper is 200 m/min and the length of the paper board is 2000 mm.更多还原
