Fault Diagnosis and Safety Strategy for Power Electricity-Driven Equipment on Vessels

This paper analyses the practical faults existing in large power electricity-driven equipment of vessels, and discusses safety strategy and driven control system optimization. The reliability is designed both in hardware and software respectively. It is of high effect that the fault tolerant is used as the non-key fault control. Moreover, the embedded system is succeeded in vessel´s control system, which also involves EMI prevent method and trouble diagnosis technology. Finally the investigated technology has applied on real control systems of the vessels successfully.
