Design and realization on the fault diagnostic flat based on virtual instrument for warship equipment

Based on virtual instrument (VI) technology, Delphi and database, etc., the fault diagnostic flat for shipboard equipment is developed in order to avoid various abuses that conventional methods brought. The modularization and universalization are proposed in its database-based design concept, realized the design of software and hardware. It broke through conventional check diagnosis patterns for warships equipment, resolved difficult to overcome problems brought on adopting existing conventional fashions examined and repaired shipboard equipment, greatly shortened the cycle of maintenance for naval warships equipment. It was proved by experiments that the flat system has merits, such as operation simpleness, high testing precision, strong flexibility and reliability and extensibility, and economical practicability. Also it is of some values for developing the other fault diagnostic instrument.
