一、序言 分布式控制系统(DCS)是为满足控制系统的需要,在4C技术(Computer、Communication、Control、CRT)迅速发展的基础上产生的。虽然它从问世至今只不过十多年的历史,但却经历了一系列变革。DCS继承和发展了模拟式仪表控制系统和计算机集中控制系统的优点,又弥补了它们各自的不足,以崭新的体系结构、技术面貌、信息处理能力和独具风格的自动控制方式赢得了人们的普遍赞赏。目前它已成为
First, the preamble Distributed Control System (DCS) is to meet the needs of the control system, 4C technology (Computer, Communication, Control, CRT) based on the rapid development. Although it has only been more than a decade old since it came out, it has undergone a series of changes. DCS has inherited and developed the advantages of analog instrumentation control system and computer centralized control system, and has made up for their respective deficiencies. With the new architecture, technology, information processing capability and unique automatic control, DCS has won the trust of people Generally appreciated. Currently it has become
