A Method for Structure Breaking Point Detection in Engine Oil Pressure Data

In this paper, a heavy-duty loader operated in an underground mine is discussed. Due to extremely harsh operational conditions, important maintenance problem related engine oil pressure. We have found that when the degradation process appears, nature of variation pressure changes. Following observation, we proposed data analysis procedure for structure break point detection. It based on specific pre-processing and further statistical analysis. The idea paper transform into nearly monotonic function describes machine condition or language—change regime inside process. To achieve goal original processing procedure. dataset analyzed covers one month observation. received confirmation during period, service has been done. purpose our research was remove ambiguity direct visualize diagnostic context. As fleet machines considered company more than 1000 loaders/trucks/drilling machines, importance approach serious from practical view. believe it could be also inspiration other researchers working with industrial data.
