Integrated Test System of Ship Degaussing Apparatus Based on virtual Instrument

For the need of testing of ship degaussing apparatus, the integrated test system based on virtual instrument technology has been designed. By describing its hardware and software in order, the designing and realizing method of the system based on the VI technology is described. This system adopts USB bus. It can be used as oscillograph, waveform generator and Muhimeter. The functions of the degaussing apparatus modules were tested and the faults were found by using the theory of fault analysis branch and diagnosis expert system. The theory of feedback control system is used to analyze the performance of the ship degaussing apparatus too. Application in testing indicates that the precision and efficiency has been improved.
