Problems solved by technology

Various methods such as this can achieve better prediction results, but their processing speed is relatively slow; moreover, different methods analyze the fault data, and the root of the analyzed data is not the fault information, thus losing the fault of the thing itself. Attributes
At the same time, some of these methods also require steps such as modeling and training, which further reduces the overall application efficiency.

Abstract

The invention discloses a fault identification method based on incomplete information, and belongs to the technical field of fault identification. The invention discloses a fault identification method based on incomplete information. The method comprises the following steps: S01, defining an incomplete set of new connotation features; S02, defining an incomplete closeness vector function, a difference incomplete closeness vector function and a product incomplete closeness vector function of a new connotation feature; and S03, giving an incomplete set fault identification method according to a set operation principle. According to the method, incomplete information can be analyzed and processed, information acquisition, processing, fault identification and decision making can be effectively and rapidly realized, and a basis is provided for combination of a subsequent incomplete information processing mode and other soft science and soft computing methods.

Description

technical field [0001] The invention relates to the technical field of fault identification, in particular to a fault identification method based on incomplete information. Background technique [0002] In recent years, with the rapid development of social science and technology and production, the work intensity of production equipment is increasing day by day. With the speed of data processing and the improvement of automation level, the composition of equipment is more complex, and the connection between local and overall systems is also closer. Often, a failure of a certain device in the system will lead to the collapse of the entire system. This not only causes huge economic losses, but may seriously endanger the lives of others, and the consequences are extremely serious. Therefore, fault identification technology plays an important role in daily production. [0003] Fault diagnosis and identification, identifying and diagnosing faults based on information such as s...
