A fault diagnosis analysis method and device

Abstract

The invention discloses a fault diagnosis and analysis method and apparatus. The method comprises the steps of creating a comprehensive object instance comprising several associated alarm sub-objects;receiving, by the comprehensive object instance, fault alarm information, determining a corresponding alarm device and a fault phenomenon, and searching for all failure causes causing the fault phenomenon and fault phenomena of the associated device caused by the failure causes; creating a virtual comprehensive object instance containing each possible cause of the alarm of each alarm sub-object and the associated failure phenomenon; and performing weighted voting and linear regression analysis on the virtual comprehensive object instance, and determining the failure cause based on the resultsof weighted voting and analysis. According to the fault diagnosis and analysis method and apparatus disclosed by the invention, by creating the comprehensive object instance, receiving the fault alarm information by the comprehensive object instance, creating the virtual comprehensive object instance, and performing the weighted voting on the virtual comprehensive object instance, the fault source is positioned quickly and accurately, real-time diagnosis of device faults is realized, and the maintenance analysis workload of device management personnel is relieved.

Description

technical field [0001] The embodiments of the present application relate to but are not limited to the technical field of fault detection, and in particular, relate to a fault diagnosis and analysis method and device. Background technique [0002] In process control or process monitoring, production and operation management enterprises often need to grasp and analyze the status of control objects or monitoring objects in real time due to specific functional requirements. As an important part of process control or process monitoring, fault diagnosis analysis has achieved great development. Fault diagnosis analysis has two meanings: on the one hand, fault location, that is, through the pre-set system structure and algorithm to diagnose the environmental status of equipment faults, and determine the precise alarm location of the equipment in the same environment; on the other hand, fault analysis, The analysis content generally includes the fault mechanism, fault mode and impa...

Problems solved by technology

[0003] However, with the continuous expansion of the scale and complexity of modern industrial processes, there are complex relationships among the various parts of the system in operation, such as power supply subsystems, computer network subsystems, and various professional management subsystems. The probability of multiple subsystems failing at the same time is high, which makes fault diagnosis and analysis increasingly difficult
