Power plant device intelligent prediction overhaul method and power plant device intelligent prediction overhaul system based on big data

Abstract

The invention relates to the big data technology field, and the object of the invention is to provide a power plant device intelligent prediction overhaul method and a power plant device intelligent prediction overhaul system based on big data. According to the invention, the maintenance data of the maintenance working can be accumulated, and the quantitative analysis can be carried out, and at the same time, the on-line update of the maintenance database can be carried out, and then the latest maintenance data support can be provided for the maintenance personnel. The power plant device intelligent prediction overhaul method based on the big data is characterized in that a fault example knowledge base can be established; initial symptoms and necessary additional remark information of an example to be diagnosed can be acquired; retrieval key factors can be formed according to the additional remark information; the retrieval in the fault example knowledge base can be carried out according to the key factors, when the complete matching is realized, and then the conclusion and the maintenance scheme of the example can be returned, otherwise the similarity of the example to be diagnosed can be calculated, and a plurality of most similar fault examples can be extracted from the fault example knowledge base, and used as the return results; whether the retrieval is completed can be determined, when the retrieval is completed, then the results can be returned, otherwise the retrieval in the fault example knowledge base according to the key factors is required to be continued.

Description

technical field [0001] The invention relates to the field of big data technology, in particular to a method and system for intelligent predictive maintenance of power plant equipment based on big data. Background technique [0002] The power plant expert system is a computer program expert system that can solve difficult problems in a specific field at the level of human experts. Familiar people gain the ability to reason through expert systems, acquire the knowledge needed, and be able to solve problems like experts or perform work similar to experts. [0003] The equipment and control systems of modern power plants are becoming more and more complex, and the requirements for maintenance personnel are very high. The training period for qualified maintenance personnel is obviously prolonged, but the maintenance personnel of enterprises are highly mobile, and some valuable maintenance experience will be lost as maintenance personnel leave or Retirement without preservation h...
