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、有效性
In order to realize the communication between microcomputer and distributed control system, this paper analyzes the structure of INFI-90 distributed control system developed by American Bailey Control Company. By analyzing the agreement of the internal communication protocol of this system, this paper designs a microcomputer and INFI-90 distributed system Communication interface, which includes hardware and software in two parts, of which software is programmed by Borland C + + language. The communication interface has been successfully applied in the AGC project of Ningxia Dam Power Plant, and its practice shows its reliability and effectiveness
