Abstract

The invention is a state monitoring-based nuclear power plant intelligent maintaining system, belonging to the field of equipment monitoring and maintaining technology. The invention comprises: memory unit, monitoring port and computer network, and calculating unit, where the memory unit is stored with original operating data of all systems, the operating data is sent through the computer network to the calculating unit, the calculating unit analyzes the operating state of the nuclear power plant from the operating data and forecasts the possible failures according to the operating state and sends out the forecasting result in two ways, one of which is sent through the computer network to the monitoring port and the other of which is sent through the computer network to the memory unit, the monitoring port real-timely displays the property forecasting results, operating data, failure conditions and maintenance information of all the systems, and the memory unit takes charge of storing the forecasting results of the calculating uint. The invention realizes the intelligent maintenance of the nuclear power plant by the state forecast.

Description

technical field [0001] The present invention relates to a system in the field of computer application technology, in particular to an intelligent maintenance system for nuclear power plants based on condition monitoring. Background technique [0002] Since the birth of nuclear power, nuclear safety issues have always been the focus of people's concern, especially the Three Mile Island accident and the Chernobyl accident, which left an inescapable shadow on many countries and the development of nuclear power. The safety standards of nuclear power plants are usually expressed by the two concepts of nuclear safety objectives and defense-in-depth principles. The overall goal of nuclear safety is to protect plant personnel, the public and the environment by establishing and maintaining an effective defense against radiation hazards at nuclear power plants. At present, the equipment maintenance methods commonly used in nuclear power plants are: (1) Reactive Maintenance (Reactive ...
