Nuclear power plant information system health monitoring and fault positioning system and method

Abstract

The invention relates to the technical field of fault diagnosis, and particularly discloses a nuclear power plant information system health monitoring and fault positioning system and a method. The system comprises a bottom data acquisition module, a diagnosis model training module and an anomaly diagnosis module, and the bottom data acquisition module is connected with the diagnosis model training module and provides training data of a nuclear power plant information system in different time periods for the diagnosis model training module; the diagnosis model training module can operate the diagnosis model, monitor monitored data of the nuclear power plant information system in real time and transmit the monitored data to the anomaly diagnosis module connected with the diagnosis model training module for abnormal state feedback when the parameters are abnormal. The method can obtain the actual operation condition closer to the system through a fault diagnosis model, is suitable for the actual operation state and management of a nuclear power information system, can quickly locate a fault, shortens the fault response time, and effectively improves the work efficiency.

Description

technical field [0001] The invention belongs to the technical field of fault diagnosis, and in particular relates to a health monitoring and fault location system and method of a nuclear power plant information system. Background technique [0002] With the continuous development of nuclear power plant information construction, the daily operation and maintenance of information systems is becoming more and more complicated. Users only use the application system itself, but the operating system, database, network environment, middleware and other parts support the operation of the application system. Once the system fails, the time cost of manual fault diagnosis is too high. However, if machine learning technology is used, the computer can judge the source of the fault, or narrow down the scope of the fault source, which will greatly improve the efficiency of diagnosis.
