工业计算机控制技术至今已经历了三个发展阶段。60年代初期到70年代中期是计算机集中控制系统时期。由于集中控制所带来的危险集中,可靠性差的问题是这种系统的主要弱点。70年代后,分散综合控制思想的提出,大规模集成电路的问世,微处理机的出现,通讯技术的发展,为新型过程控制系统的研制创造了条件。一个以分散的控制适应分散的对象,同时又以集中的监视、管理达到控制全局目的的新的过程控制系统出现了。这就是1975年问世的分散型综合过程控制系统,我们简称为分散控制系统。这一时
Industrial computer control technology has gone through three stages of development. From the early 1960s to the mid-1970s was the period of computer centralized control system. The problem of poor reliability is a major weakness of such a system due to the concentration of hazards brought by centralized control. After the 1970s, the introduction of decentralized control theory, the advent of large-scale integrated circuits, the emergence of microprocessors, and the development of communication technologies have created the conditions for the development of a new type of process control system. A decentralized control accommodates decentralized objects, and at the same time emerges as a new process control system for centralized control and monitoring of the overall purpose. This is the decentralized integrated process control system that came out in 1975, which we refer to as a decentralized control system. This time
