用于取样积分器输出的单片机控制装置

THE CONTROLLING DEVICE OF SINGLE-CHIP MICRO-COMPUTER FOR BOXCAR'S OUTPUT

本文介绍了用Mcs—51单片机控制取样积分器输出的方法及原理,还详细介绍了该控制装置的硬件框图和软件流程图。取样积分器输出波形周期很长,在普通示波器上难以直接显示。若用该装置控制取样积分器的输出,即可实现在普通示波器上直接显示的目的,并能达到边采样、边处理、边显示,模拟了函数记录仪的全部功能,是显示取样积分器输出波形的最新方法。该控制装置既经济、体积小,又操作方便,在教学实验和科学研究中是很受欢迎的。

This article introduces the method and principle of Boxcar's output under the control of a single-chip micro-computer. Moreover, the article offers a detailed picture of the hardware frame diagram and the software folw diagram in the controlling device of such a Single-Chip Micro-computer. The waveform generated by Boxcar has such a long circle that generally speaking,it is impossible for ordinary oscilloscope to display it. By using the controlling device, however, the waveform can be easily displayed on an ordinary ossilloscope. This controlling device helps achieve the goal of sampling, processing and displaying simutaneously; furthermore, it simulates every function of X-Y recorder. It is economical,small in volume, and convenient in operation. This is the up-to-date method in displaying the waveform by Boxcar,and is very popular in today's teaching experiments and scientific researches.
