Electromagnetic Clutch Based High-Low Carpet Jacquard Control System

This paper proposes a developed electromagnetism clutch based high-low carpet jacquard control system for tufting carpet machine. Base on the principle of typical tufting carpet jacquard mechanism, design the hardware structure of jacquard control system. The system composition and working principle are introduced in detail. The control system transforms carpet design patterns into machine control information, outputs control information through the I/O control card, and power driver board captures the control information and drives clutches to change its status, and then controls the yarn tension to realize the digital jacquard in tufting carpet. By analysis the process of jacquard, design the software modules of control software, use bitmap as a pattern representation, design the flow chart, and the interface of control system. Finally develops the control software with C++ and realize the carpet jacquard function.
