摘要: 仪控技术管理如风险分析、安措分析、核电厂分布式控制系统（DCS）文件管理等，是核电厂仪控工作领域的难点和重点，为降低因仪控工作准备不充分而产生的机组非预期缺陷和停机停堆风险，基于对DCS工程文件及设计文件的研究，开发了一套智慧维修辅助系统。该系统对接现场人员高频使用场景，辅以计算机数据库信息建模技术，实现了DCS组态智能分析、DCS系统状态监测、自动风险提示、一站式检索功能，可以有效提升核电仪控调试和维修领域信息化管理水平，提高人员工作效率。Abstract: The management of instrument and control technology, such as risk analysis, safety measures analysis, and DCS file management, is a difficulty and focus in the field of instrument and control work in nuclear power plants. In order to reduce unexpected defects and shutdown risks of units caused by inadequate preparation for instrument control work, based on the study of DCS engineering documents and design documents, a set of intelligent maintenance assistance system is developed. This system interfaces with high-frequency usage scenarios of on-site personnel, supplemented by computer database information modeling technology, achieving intelligent analysis of DCS configuration, DCS system status monitoring, automatic risk warning, and one-stop retrieval functions. It can effectively improve the level of information management in the field of nuclear power instrument and control debugging and maintenance, and improve personnel work efficiency.
