Abstract

According to the applications of stepping motor in industrial controlling fields, an intelligent control system is designed based on personal computer and single chip machine in this paper. The working principle and control mode of stepping motor are introduced firstly. Then, the hardware of single chip machine system is introduced; especially the crystal oscillator circuit, driving circuit, power circuit, LED display circuit, watchdog circuit and serial communication circuit are analyzed in details. Finally the software including motor controlling program, communication program and human-machine interface program are designed. The practice showed that the system has the characters of good performance and low cost, so it can be widely used in stepping motor controlling.

Keywords:
