概述数字式控制装置采用了微型计算机,是目前最新的流程控制手段,在过去20多年中,从硬件技术、从所使用的元器件以及从所实现的目标来看都发生了很大的变化。在自动化仪表发展的进程中,1971年以来发表的微型计算机对其影响很大,1975年美、日等国各专业仪表制造厂和电力机械制造厂都先后发表了采用微型计算机的多回路
Overview Digital microcontrollers, using the latest in process control, have changed dramatically in the past two decades in terms of hardware technology, the components used, and the goals that have been achieved. In the process of the development of automation instruments, microcomputers published since 1971 have a great impact on it. In 1975, various professional instrument manufacturers and electric machinery factories in the United States, Japan and other countries all published multi-circuits
