摘要

Electronic jacquard control system is the core technology of tufted carpet equipment, whose dynamic characteristics determines the quality of tufted carpet surface(the roughness, the level of loop transition phenomenon).In this paper, the structure of jacquard control system is analyzed. And the concept of roughness of carpet surface is given. Its evaluation model is established. Through analysis of structure, we point out that the key factor affecting the quality of carpet surface is signal acquiring unit which is investigated in this paper. We analyze the characteristics of system and the quality of the carpet surface, also establish the model of relationship between the synchronous sampling frequency of stepper motor and the height of carpet loop. Using this simulation model, we get the optimal synchronous sampling frequency of stepper motor to ensure the quality of carpet surface, also provide a theoretical basis for the design of control system.
