摘要
介绍了一种基于PC机与AT89S51单片机串口通信的三相异步电机控制系统,PC机以VC6.0为开发环境,实现了上位机软件的编制。AT89S51以交流固态继电器为接口器件,实现了三相异步电机的驱动与控制。该系统达到了软件控制电机启停的目的,并给出了硬件与软件程序。整个系统结构简单,实用性强,应用前景广阔。
A control system of the threephase synchronous motor based on the serial communication of PC and hT89S51 is introduced in this paper. The software system on PC is implemented by using VC6.0 as developing environment, while the AT89S51 controls the threephase synchronous motor through the AC SSR（solid state relays）. The controlling of the threephase synchronous motor through software on PC is achieved, as well as the programme is given out in this paper. The system has a widespread application prospect with its simple structure and high practicability.
