两坐标步进电机驱动运动工作台控制系统的设计

设计是完成一两坐标步进电机驱动运动工作台控制系统的设计；完成交流电机启停的电气控制系统设计。其硬件部分共包括键盘操作、单片机控制、输入电路、控制电路、显示电路等五个主要组成部分。设计的总体思路是准确安全的对工作台和电机进行控制。
    位置信号和按键信息通过传输线传送给单片机和键盘接口芯片，数据经过处理，将按键信息串行方式传送给单片机，单片机通过相应的程序，向控制回路发送控制信号，进而控制工作台的动作，实现对硬件设备的控制。

关键词：键盘操作，单片机控制，数码管显示。

Abstract：The design is completed on January 2 coordinates stepper motor driven campaign platforms control system design; complete AC motor COMMITMENT electrical control system design. Part of its hardware, including keyboard, microcontroller control, input circuits and control circuits, display circuit, the five main components. The overall design is an accurate idea of the table and the safety of motor control.
Position signal and key information transmitted to the transmission line through the MCU and keyboard interface chip, a data processing, key information will be transmitted to the serial microprocessor, microcontroller through relevant procedures, sent to the control loop control signal and then control table action to achieve the control of the hardware equipment.
Keywords: Keyboard operation, SCM control, Digital Display。
