摘　　要：基于TMS320F2806主控芯片,选择东芝TB6560作为驱动芯片设计单轴运动控制平台,步进电机通过联轴器带动滚珠丝杆旋转将回转运动转换为直线运动。给出了TB6560驱动电路、上位机串口通讯及EEPROM掉电存储电路。在Matlab平台仿真梯型加减速曲线在线实现,设计VB6.0环境的的基于RS232通信协议的上位机控制界面,并在CCS编译平台调试完成丝杆运动单元的点位运动控制。测试结果表明:该系统运行平稳、噪声低、定位准确、抗干扰性强,可以满足数控加工课程教学需要。A single-axis motion control teaching platform is designed by using TMS320F2806 digital signal controller （DSC） as a core and the step motor integration driver chip TB6560.Ball screws rotational movement is converted into linear movement through the coupling.Driver circuit,PC serial communication and EEPROM power-off memory circuit are also provided.In addition,Trapezoidal-Curve algorithm is derived and can be simulated on Matlab platform.PC interface is realized in VB6.0 based on RS232 protocol.All the single-axis motion control software is also debugged in CCS compiler environment.The test results show that the system is smooth and has low noise,accurate positioning,strong anti-disturbance.The controller can satisfy the NC machining teaching.
