近十年来,采用微处理器的各种工业控制装置──程控装置、数控装置、数据通信装置、信号处理装置等相继发展而得到应用。这种发展趋势使工业控制计算机形成了鲜明的特征,即开放式结构与总线系统,如S-100总线、Q总线、Multi Ⅰ和Ⅱ总线、VME总线、STD总线,Bit总线以及IBMPC/XT/AT总线等。尤其是微电子-通信-CRT-控制技术的广泛采用,给工业控制计算机的发展带来了新的生机。近年来由于分布式体系结构与集中式体系结构互为补充更使新技术、新工艺、新产品层出不穷。
In the past ten years, various industrial control devices using microprocessors ─ ─ program-controlled devices, numerical control devices, data communications devices, signal processing devices have been developed and applied. This trend has led to the emergence of industrial control computers characterized by open architecture and bus systems such as S-100 bus, Q bus, Multi I and II bus, VME bus, STD bus, Bit bus and IBMPC / XT / AT bus and so on. In particular, the widespread adoption of microelectronics-communications-CRT-control technology has brought new life to the development of industrial control computers. In recent years due to the distributed architecture and centralized architecture complement each other more so that new technologies, new processes, new products emerge in an endless stream.
