【Abstract】 Using intelligent equipment in nuclear power plant can improve the fault diagnosis ability and the real-time monitoring ability of nuclear power plant. Considering the characteristics of nuclear power plant process system and the distribution of measurement and control points,this paper puts forward the design scheme of communication interface between the different types of intelligent equipment and the digital instrumentation and control(I&C)system of nuclear power plant. The general configuration and interface methods of digital I&C system are given. The intelligent equipment interface schemes with the digital I&C system of nuclear power plant are analyzed in details,including the fieldbus type intelligent equipment,third party control system,remote I/O system,auxiliary control network system and the intelligent wireless communication system. The designed interface scheme realizes the system integration of intelligent equipment and digital I&C system of nuclear power plant,and improves the control performance and equipment management ability of digital I&C system in nuclear power plant.更多还原
