Abstract

The invention discloses an expert system-based intelligent fault diagnosis system for a marine diesel engine. The system comprises an HMI client, a sensor acquisition module, a data processing module,a data storage module, an expert diagnosis system, a field communication module and a remote communication module. According to the system, the current fault type is intelligently judged by utilizingthe expert system; data parameters acquired by a diesel engine sensor are analyzed in real time, so that a fault reason is accurately diagnosed and a fault position is positioned; and a fault emergency maintenance policy is given. A quick maintenance scheme can be provided for technicians or after-sales service personnel, so that the service efficiency is improved; and a role-based management function is designed for the system, so that different system management permissions are set for users, and the safety and maintenance of system operation are facilitated.

Description

technical field [0001] The invention relates to an intelligent fault diagnosis system for marine diesel engines based on an expert system, and belongs to the technical field of equipment fault diagnosis. Background technique [0002] As the "heart" of ship power, the diesel engine will cause serious economic losses and even endanger life safety once it fails. Based on the analysis of the actual situation, there are many reasons for the failure of marine diesel engines, and it is necessary to apply appropriate diagnostic techniques according to the characteristics of different manifestations to maintain a stable operating state. When analyzing the cause of the fault, it is necessary to comprehensively analyze various factors according to the structural complexity of the fault and the particularity of the operating environment to improve the accuracy of the fault diagnosis result. [0003] Marine diesel engines have many moving parts and complex structures, making fault diagn...
