文档介绍：基于单片机的步进电机控制系统设计
摘要
;利用单片机的通用同步/异步串行口与PC通信,接收PC送来的控制信号,控制步进电机的工作状态;也可以通过对按键的操作完成步进电机的手动控制;通过在电机车轴上安装牙轮磁环,利用霍尔传感器检测电机的实时转速;电机的当前工作状态、转速、步长、步进方式等均可以由PC或键盘来设定,并在LCD上显示出来。
同时本文详细论述了整个系统的整体框图和各模块的具体功能。整个控制器的操作方便、快捷且性能稳定可靠。当然,在设计中存在的一些问题,以及影控制精度的因素,和解决这些问题的可行性方法都作了详细的说明。

Summary
This text introduces to take a machine of 89 S52s as the core controller to tread the design method that controls the system into the electrical operation function that makes use of a machine outputs to tread into the electrical engineering work need of pulse electric voltage electric current;Make use of a machine in general use synchronous the difference treads the string to go the and PCs correspondence, receiving the control signal that PC deliver, controling to tread into the work appearance of the electrical engineering;Can also move the control through a hand pletes to tread into the electrical engineering to the operation of the key;Pass to install the gear ci wreath on the electrical engineering axle, the solid hour that make use of the huo er to spread the feeling machine examination electrical engineering turn soon;The current work appearance of the electrical engineering, turn soon, tread long, tread into the way etc. all can be set by the PC or keyboards, and on the LCD the e out.
At the same time detailed treatise of this text the whole frame diagram of the whole system and concrete function of each mold operation convenience of the whole controller, fast and the function stability , some problems exist in the design, and the ying control the factor of the accuracy, definitely reach agreement these problem of possibility methods all made the expatiation.
