Application Research On Marine Transportation Equipment Fault Diagnosis Based On Fault Tree

The marine transportation equipment is an important part of large ships'supply system. In order to improve the efficiency of goods transportation, it is mainly to get the rapid transit which is from supply areas to the destination area.Because the marine transportation equipment is responsible for the rapid transportation of supply goods, which needs the long-running equipment in the process of supply goods, so it requests the whole transportation equipment to have high reliability and safety, as well as the daily safety management and maintenance performance management. According to these, it needs to find the problem with the transportation equipment as quickly as we can. Therefore, we should research and analyze the malfunction of the transportation equipment.This essay will talk about the fault diagnosis of the marine transportation equipment is based on the "fault tree". First, it will classify and analyze the sample information of the marine transportation equipment, and set up the model of "fault tree" diagnosis. Combine to take it as basis, to gradually, to deduce and find out the breakdown reason. Second, it will discuss the method deeply, which is based on the "fault tree " contribution of each component that is in the small contribution method of the "fault tree", the resulting of the "fault tree" of whole marine transportation equipment.In this paper, based on the fault tree method based fault diagnosis expert system, Through the application of fault diagnosis expert system, it can be found quickly and solve the safety risks and failures in the use of conveyor, and identify the fault, so that the fault can be quickly solved out, improved the rate of fault diagnosis information processing. In this way, it can improve plant operation's safety, stability and reliability, and ensure supply goods deliver to the destination quickly, safely and reliably.
