摘要
为提高相位测量系统的稳定性和精度,提出一种新的针对相位差测量的解决方案。该方案基于高主频微处理器C8051F410,运用移相技术,双路采集具有相位差的同频信号,经C8051F410的DSP内核处理,精确的测出相位差值。试验证明本系统具有较高的稳定性和精度,系统简单实用,具有广泛的应用价值。
A new phase measurement solution is proposed, thus to improve the stability and precision of phase measurement system. This solution, based on high master frequency microprocessor C8051F410, by using shift-phase technology, and by collecting two same frequency signals of different phase in double-channel, which is then processed by the DSP kernel of C8051F410, precisely measures the phase-difference value. Experiment indicates that this system is of high stability and precision, and is simple and practical, thus could be widely applied.
