The system design consists of hardware design and software of two parts. Among them, the minimum system, power template, stepper motor drive hardware design includes AT89C52 microcontroller (Darlington driver ULN2003) a total of 3 function module design, and realize the organic combination and each module on the circuit board. Software design including control program of upper computer software control, stepper motor pulse and the speed signal acquisition module, and ultimately to achieve the control of stepper motor rotation direction and speed, and the speed of stepping motor in dynamic display of PC software, the speed for real-time monitoring display. The software adopts the editor in the Keil software environment of C language. The characteristics of this system is intelligent, practical and reliable.
