从通信的角度对核电站数字化仪控平台进行了分析和研究。结合国际普遍采用的IEEE标准等，以APWR项目核电站所应用的数字化仪控平台为研究对象，重点介绍和分析了该平台的整体通信架构及应用的通信技术。同时，根据相关法规标准及任务需求说明，对APWR的仪控平台通信架构进行进一步修改和完善。修改之后的通信架构不但提高了驱动可靠性，降低了系统的响应时间，而且降低了多层通信带来的风险，提高了安全性能。%The digitized instrument control system ( I&C ) platform of nuclear power plant ( NPP ) is analyzed and researched from the perspective of communication. Combining with the commonly used international standards, such as IEEE, etc. , with the digitized I&C platform applied in NPP of APWR project as research object, the overall communication architecture and communication technologies applied for such platform are introduced and analyzed emphatically. In addition, based on relevant regulations, standards, and requirement description of the task, the communication framework of I&C platform of APWR is revised and improved in further. The revised communication framework improves the driving reliability and reduces the response time of the system; furthermore, the risk caused by multiple layer communication is reduced, while the safety performance is improved.
