摘要
介绍了一种用单片机来实现自动测速的测量方法。讨论的是软件部分的设计,包括键盘、计数、数据处理、代码转换、显示这几个部分。此系统采用溢出计数,1s定时,动态显示,实施测量。精度优于1%,测量最高转速2000r/s,测量延时不超过1s。
The automatic measure system of microcomputer is introduced. The software design is mainly discussed. It is composed of the keyboard, the counter, the handling of data, the changing of code, the showing and the warning. In this system, overflowing count and changed show are used. The detecting accuracy is better than 1% while the measuring max reaches 2000 r/s. The measure delaying is not more than 1s.
