| 摘 要： | 用Ｖ／Ｆ转换器实现Ａ／Ｄ转换在微机控制的测量领域中应用相当广泛，但使用常规的测量方法，其测量精度和速度都较低，限制了Ｖ／Ｆ转换器的使用范围。本文通过巧妙应用ＡＴ８９Ｃ５２单片机中Ｔ２的特殊功能，集测量频率和测量周期为一体，成功地解决了上述矛盾，有效地提高了Ｖ／Ｆ转换的测量精度和测量速度。

| Abstract: | Using V/F-converter( VFC) to realize the A/D transfer is widely applied in the microcomputer-controlled measurement field. But, because of the low measurement precision and speed of common method, it limited the application area of the V/F converter. In this paper, based on investigating the special function of T2 in single chip microcom-puter(AT89C52) , the integrated method of measuring the frequency and the circle was developed , then, the measurment precision and the speed of the V/F conversion was improved effectively. |
