摘要
本文主要介绍PC—1500计算机对16路位移传感器送来的信号进行数据采集的接口电路原理。接口电路采用十进制硬件计数方式,对脉冲信号进行计数;程序编制采用PC—1500机器语言和BASIC语言的混合编程。文中对MC6821 PIA芯片的初始化程序、读数程序以及基本程序作了说明,并给出它的流程图。
The paper mainly deals with the principle of. PC-1500 computer's interface circuit which collects signals from the 16-way displacement sensors. The interface circuit adopts the decimal hardware counting system for counting pulse signals.Combined programing is performed in PC-1500 machine language and BASIC language. The initializing program, reading program and basic program of MC6821 PIA chip are illustrated and the flowchart is given.
