摘    要：本文论述了用Z-80单板机构成数字触发器的基本原理和具体方法,并给出触发器的部分电路、程序框图以及实验结果。随着DDC控制的发展,近几年来国外已研究出若干种数字触发器。我们研制的触发器不同于这几种,它由单板机上现有的硬件资源——Z80 CTC与软件相结合组成。这种触发器具有结构简单精度高,占用CPU时间少等优点。因而,一台单板机能实现多项功能,较好地发挥了单板机的潜力。该触发器通用性好,可应用于计算机控制的各种可控硅系统。

Abstract: The fundamental principles and the practical methods of the digitalcomposed of Z-80 single board computer were studied. The program blockdiagram, partial circuits and the experimental results are given in thispaper. In recent years, with the development of the DDC control system, anumber of digital triggers have been obtained abroad. The trigger whichwe have obtained is diffirent from theirs. It is composed of both hardwareresources of Z80CTC and software of the single board computer. The triggerpossesses a great number of advantages: simple structure, high precision andless CPU etc.. Its latent capacity can be developed. This trigger has betteruniversality and therefore can be used in various drive systems of SCR controlled by computers.
