小型智能测速仪的设计

The Design of a Mini-intelligent Measuring Speed Instrument

介绍一种以 ＡＴ８９Ｃ２０５１单片机为核心，配上简单实用的外围电路构成的小型智能测速仪。它在设计上充分利用了单片机的内部资源和Ｉ／Ｏ口，基本上做到了最优化和最小化设计。

This paper introduces a kind of digital measuring system, which is based on a chip-computer AT89C2051. The meter has a good capability in wide fields.
