Abstract
Smart devices based on the microprocessor compare to the traditional equipment, which can improve the signal accuracy and self diagnosis of equipment. Field bus is used to provide industrial data bus for communication, which not only transfers the site process signal to the Digital Control System (DCS), but also transfers the self diagnostic information and maintenance data to the DCS. The adoption of field bus for Smart devices will change the traditional DCS structure, which means that the input and output modules will be embedded on the site. Field bus can enhance the ability of data acquisition and processing. In the nuclear power plant (NPP), considering the environment is different between the conventional industrial and high reliability requirements, the application of field bus should be carefully analyzed. Based on this, this article analyzes the feasibility of field bus technology in NPP, and gives the application principles, which lays a foundation for the actual project.
