| 摘 要： | 提出了一种具有矩阵结构的多路电压/频率变换技术,即多路模拟开关用于行线上的通道切换,同时可编程定时器和电压/频率变换器实现列线上的信号采集。分析表明它要比常规的串行或并行多路变换技术具有更优越的性能。本文还介绍了运用这种方法和 MCS-51系列单片机接口的-48路信号采集系统.

| Abstract: | A multichanol V/F conversion tochnique with a mari construction in described idetail,with the multicha-el analogue switches select the row path of signal,and programmable timers make the data acquisition each column simultanconsly with V/F converters.Analysis shows this method have evident advantage over the conventional serics or parallel acquisition me'hod.A 48 channel data acquisition system interfaced to a MCS-51 series single-chip microcomputer in introduced as an example of this method. |
