摘要
以LM331型V/F变换器为例,叙述了如何把采集的电压信号通过LM331V/F转换器精确变换成频率信号送与单片机实现数据采集控制的方法。详细介绍了系统各部分的构成、原理及用C语言进行测量控制的编程方法。
This paper takes LM331 V/F convertor produced in USA for instance, it introduces a new way that how we can convert voltage signal having been collected to frequency signal with LM331 V/F convertor, and then how we can transmit the frequency signal to SCM in order to reality data collection controlling. It also detailedly says the system＇s structure, its＇ operational principle and the way of programming with C language.
