摘要
正弦交流信号有效值的测量，需要测量正弦信号的峰值，利用正弦信号有效值的计算公式就可以得到正弦信号的有效值。要进行基于单片机的正弦信号有效值的测量，需要先将模拟量转换为数字量，将所得的数据经由单片机处理，再将最后的结果显示出来。设计的电路主要包括信号采集与转换电路，单片机控制电路和显示电路。其中，有效值的计算在本次设计中主要利用软件部分的设计完成。 关键词：有效值测量，模数转换电路，单片机控制
Abstract
Sinusoidal ac signal effective value measurement, need to measure the peak value of the sine signal, using the sine signal effective value calculation formula of the effective value of sine signal can be calculated out. Must carry on the sine signal RMS measurement based on single chip microcomputer, need to convert analog to digital quantity, will the data processed by single chip microcomputer, then the final result of display. Design the circuit mainly includes signal acquisition and conversion circuit, SCM control circuit and display circuit. Among them, the RMS calculation in the design of the main use of the design of the software part is complete. Keywords: RMS measurement, modulus conversion circuit, single chip microcomputer control
