Research and Application of Intelligent Maintenance Assistance System

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.
