Embodiment 1

[0038] refer to Figure 1~5 , which is the first embodiment of the present invention, this embodiment provides a method for evaluating the probability of equipment failure based on text mining, including:

[0039] S1: Perform failure mode impact analysis on relevant equipment. It should be noted that the failure mode impact analysis of related equipment includes related equipment, each of which is composed of multiple smaller components, and the components exhibit different failure modes; according to the characteristics and uniqueness of related equipment, the equipment is divided into Several parts, and each part is further divided into different components and corresponding failure modes, which are classified and numbered to form failure texts, so that components can be associated with their corresponding failure modes;

[0040] Wherein, the fault text includes, and the more comprehensive the fault text record is, the higher the accuracy of fault probability calculation is...

Embodiment 2

[0058] refer to Figure 6 , is the second embodiment of the present invention, which is different from the first embodiment in that it provides a text mining-based equipment failure probability evaluation system, including: analysis module 100, data classification module 200 and calculation Module 300. More specifically, the analysis module 100 is used to analyze the impact of the failure mode on the relevant equipment, and upload the analysis results to the data classification module 200; the data classification module 200 is used to analyze the text recorded during the operation of the relevant equipment The data is classified, and the classification result is uploaded to the calculation module 300; the calculation module 300 includes a component calculation unit 301 and a device calculation unit 302, wherein the component calculation unit 301 is connected to the data classification module 200 and can receive data uploaded by the data classification module 200. The classifi...

Abstract

The invention discloses an equipment fault probability evaluation method and system based on text mining, and the method comprises the steps: carrying out the fault mode impact analysis of related equipment; classifying the text data of the related equipment operation record into a correct fault mode by utilizing a text mining technology; according to the correct fault mode and the influence analysis, calculating the fault probability of each part and each component of the related equipment; integrating the fault probability of each part and each component, and calculating the fault probability of the related equipment. Through the text mining and other informatization technologies, the problem that it is difficult for a traditional manual mode to achieve fault mode classification in a large number of fault records with various subtle differences is solved; meanwhile, by means of a bag-of-words model, a Weber distribution function and the like, fault reports are automatically classified into different fault modes of different devices, and finally, the automatic acquisition of equipment fault probability evaluation is realized, and an objective basis is provided for decisions of equipment replacement, maintenance and the like.

Description

technical field [0001] The present invention relates to the technical field of energy Internet, in particular to a method and system for assessing equipment failure probability based on text mining. Background technique [0002] In recent years, energy Internet equipment must face maintenance and replacement during the long-term operation process to ensure the normal, stable and continuous operation of the system. However, whether to replace specific equipment in time or continue to use after maintenance involves the rationality of investment and requires objective decision-making. Risk quantification is an indispensable element in objective decision-making, the most important of which is the need to quantitatively evaluate the probability of equipment failure in order to make accurate decisions. [0003] In the maintenance of equipment and facilities, an "abnormal accident report" (including text) is often recorded when an accident occurs. However, text data in reports is...
