Improved Fault Petri Nets of Unmanned Seafloor Drilling Based on Traces Transition

ABSTRACT Yang, J.; Tang, Z.; Wang, Z.; Wang, X.; Huang, Q., and Wu, M., 2018. Improved fault petri nets of unmanned seafloor drilling based on traces transition. In: Liu, Z.L. and Mi, C. (eds.), Advances in Sustainable Port and Ocean Engineering. Journal of Coastal Research, Special Issue No. 83, pp. 479–485. Coconut Creek (Florida), ISSN 0749-0208. For this kind of complex system equipment, parts fault detection of single large difficulty and low efficiency from the whole system considering many factors can lead to failure, and these factors affect each other, and the fault also exists between some logical relations, because of the condition monitoring and fault diagnosis accurately and effectively is very difficult. Based on the analysis of the traditional Petri Net application in the field of fault diagnosis, this paper gives fault diagnosis modeling expression of different classification problem & a kind of theory, and introduces transition token matrix representation of traces transition in order to ...
