設計是完成一兩坐標步進電機驅動運動工作臺控制系統的設計；完成交流電機啟停的電氣控制系統設計。其硬件部分共包括鍵盤操作、單片機控制、輸入電路、控制電路、顯示電路等五個主要組成部分。設計的總體思路是準確安全的對工作臺和電機進行控制。
??? 位置信號和按鍵信息通過傳輸線傳送給單片機和鍵盤接口芯片，數據經過處理，將按鍵信息串行方式傳送給單片機，單片機通過相應的程序，向控制回路發送控制信號，進而控制工作臺的動作，實現對硬件設備的控制。

關鍵詞：鍵盤操作，單片機控制，數碼管顯示。

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。
