Process visualization decision making diagnostic system and inference control method of process visualization decision making diagnostic system

Abstract

The invention discloses a process visualization decision making diagnostic system and an inference control method of the process visualization decision making diagnostic system. The system comprises an expert knowledge base module, an expert knowledge explaining module, a decision making inference module and a fault tree analysis module. The decision making inference module is connected with the expert knowledge base module, the expert knowledge explaining module and the fault tree analysis module through corresponding interfaces. By means of the process visualization decision making diagnostic system and the inference control method of the process visualization decision making diagnostic system, the visualization of the inference process under human-computer interaction is achieved, and a user can take part in the fault diagnosis process accordingly; in addition, the inference process is visual for the user, the suspicion of the user to an expert system inference conclusion can be canceled accordingly, and the control method is simple and practicable.

Description

technical field [0001] The invention belongs to the technical field of fault diagnosis in the field of aerospace, and in particular relates to a process visualization decision-making diagnosis system and a reasoning control method thereof. Background technique [0002] At present, on-site analysis, judgment and handling of faults in line maintenance often rely on the degree of grasp and experience of the maintenance personnel on the mechanism of the equipment, resulting in inaccurate fault location and long maintenance time. [0003] However, most of the existing diagnostic techniques based on expert systems give the final diagnosis result once by comparing the observation set with other fault sets, and through forward reasoning or reverse reasoning. Therefore, the reasoning process is invisible and unintuitive, and users cannot directly participate in the reasoning process. As a result, they are skeptical about the conclusions of many expert system reasoning. Contents of ...
