Based on the characteristics and performance of the predictive maintenance system of turbine generator and the requirement of data,the collection and analysis of algorithm of data is researched and designed.

With the predictive maintenance (PM) being popularized in enterprise, the fault prediction technique is getting more and more attention.

Combining with the research in fault diagnosis and predictive maintenance system for the mechanical and electrical equipment in a wanship, this paper presents the constitution of predictive maintenance data base, the determination of alarm parameters and in practical application in naval vessels.

The key technology of maintainability test for naval ship-borne electronic equipment;

The functions of general maintenance & test system for airborne weather radar is introduced, and the scheme based on advanced VR instruments platform-PXI technique and the software structure of general maintenance & test system are presented.
