HRD Fault diagnosis using hybrid method of deep learning and signal processing

Background of research

HRD is used in many drilling operations like excavation and it is important in mining industry. As HRD frequently operates under harsh conditions, diverse failures modes occur and these makes potentials for personal injuries and economic losses. So, Reliable and prompt fault diagnosis method is needed to ensure safety from accidents

1. Black box optimization problem

  • The black box optimization problem refers to an optimization problem with unknown relationships between objective functions, constraints, and determinants. Specifically, it refers to a problem in which you do not know the objective function value according to the decision variable or whether you satisfy the constraint without additional experiments and measurements.
