平锁缝纫机运动控制卡设计

Designing of the lockstitch buttonholing machine motion control card

针对平扣眼锁眼缝纫机结构复杂,电器器件多,控制复杂的特点,在对平扣眼锁眼锁眼机的功能特征、系统结构、人机操作界面等问题的深入分析的基础上,提出了一种基于DSP和FPGA的平扣眼锁眼缝纫机运动控制卡的设计方案,该方案集成了运动控制、交流伺服控制、步进驱动控制、接口控制等功能,具有通用性好软件易于修改升级调试方便等特点。经现场应用结果表明,各项指标完全满足设计要求,得到了很好的实际应用。

According to complexity of lockstitch buttonholing machine structure,too many electrical devices needed to control, a approach of the designing computer-controlled lockstitch buttonholing machine motion control card based on DSP and FPGA is presented by analyzing function characteristics, system structure, man-machine interface.Motion control、AC servo control、stepper drive control and interface have been integrated the approach,which has been proved to have several features of good adaptability, easiness of software modification or update and convenience for debugging. Application results show that the indicators meet the design requirements,and have a very good practical application.
