【摘要】 针对间歇控制系统对象复杂、模拟量和开关量控制时间要求不唯一等特点，在对现存的ＰＬＣ、回路调节器、工控机、ＤＣＳ等控制方案进行分析比较的基础上，提出了一种更加简洁、可靠、经济的现场总线控制系统方案．这种控制方案已在多个控制系统中得到了成功应用．更多还原

【Abstract】 The object of Intermittent Control is more complicated than any other control, and it has vrious demand on control time. Aimed at these characteristics, this article analyses the present control schemes , such as PLC,regulators, industry computer DCS, and presents a more simple, more reliable,more economical Field Bus Control System scheme. this scheme has been applied successfully in many control systems.更多还原
