摘要
综述了过程控制集散系统的结构、特点及其优越性，指出了这一系统在工业控制中，主要以采集、显示数据为主，兼以打印、管理，尚未构成系统的基本控制单元，而只有Ｉ／Ｏ接口单元，显示了集散系统可分批投资、受益的优越性。
The paper deals comprehensively with structures of the lumping & spreading system during the procedures control, including its features and advantages. It points out that this system hasn′t so far formed its basic units in industry control, with sampling, data displaying as its main functions accompanied with printing and handling. However, only the interface unit I/O can show the advantages that the system can be invested and benefited in instalments.
