在这一讲里从用户使用角度,对可编程调节器的构成作一介绍。深入了解必须具备微型计算机原理方面的知识,但对用户来说则无必要。我们这里介绍硬件构成框图,指出功能,便于以后各讲逐步深入说明仪表功能特点,起到过渡作用。另一方面,了解一些硬件方面知识,便于将来选择使用仪表时能对其性能优劣作些比较。 In this talk from the user’s point of view, the composition of the programmable regulator to make an introduction. In-depth knowledge must have knowledge of microcomputer principles, but not necessary for users. We are here to introduce the hardware block diagram, pointed out that the function, easy to explain in detail after each instrumentation features, play a transitional role. On the other hand, to understand some of the hardware aspects of knowledge, to facilitate the future choice of the performance of the instrument can make some comparisons.
