【摘要】 针对一体化氧化沟生物处理系统控制问题，给出一种实用、基于ＣＡＮ总线的现场控制器与工业ＰＣ（ＩＰＣ）组成污水处理分布控制（ＤＣＳ）系统实现方案。由于该方案采用的现场控制器具有多主结构、实时能力和高可靠性通信，而集中监控的ＩＰＣ资源丰富，故整个ＤＣＳ系统开放性、实时性、可靠性和操作性良好。更多还原

【Abstract】 To the control problems in the biology processing system of integrated oxidation ditch, the DCS system practical scheme that consists of practical, field bus based ADAM-5000/CAN series and IPC is presented to sewage treatment at some factory. The scheme that adoptes ADAM-5000/CAN in the field has the characteristics of multi-master structure, real-time capability and high reliability communication. Besides the IPC that integrates monitor with control has rich resource, thus the DCS system possesses reliable open system architecture, quality real-time capability, high reliability and expedient operability.更多还原
