摘要
利用一简单的光电发射及接收电路,将转速变为电脉冲并输入微机,形成一精确的微机测速系统。本文介绍了系统硬件和软件,并对测速精度进行了讨论。
An accurat microcomputer measur- ing system for rotating speed is assembled by utiliz- ing a simple photoelectric emitting and receiving cir- cut,in which rotating speed is changed into electric pulse and input into microcomputer.Besides having an introduction to hardware and software of sys- tem,the accuracy of speed measuring had been dis- cussed in this paper.
