摘　　要：为了实现微机直接与集散控制系统间通信， 详细分析了美国贝利控制公司研制的ＩＮＦＩ－９０集散控制系统的结构组成， 通过剖析该系统的内部通信协议约定，设计了微机与ＩＮＦＩ－９０集散系统通信接口，它包括硬件和软件两部分，其中软件由Ｂｏｒｌａｎｄ Ｃ＋ ＋ 语言编程实现。该通信接口已在宁夏大坝电厂的ＡＧＣ工程中获得成功应用， 实践表明了其可靠性。In order for a computer to communicate directly with the Distributed Control System(DCS), this paper explains the structure of the INFI 90 type DCS made by the Baily Control Company in America in detail. By means of analyzing its inner agreement on communication, an interface between the INFI 90 type DCS and the computer is designed, which includes the software and hardware. Its software is compiled in Borland C++ language. This interface has been put into use successfully in the AGC project of the Ningxia Daba Power Plant, and the practicle has shown its reliability and effectiveness.
