Study and design of sine servomechanism test instrument based on multi-source information fusion

Sinusoidal machine is an important device in naval vessel maintenance supporting, but it has some shortcomings such as single function and hard to taken. Under modern combat conditions, we need quick guarantee. In view of the above mentioned facts, we have designed a portable synthetic detection and testing instrument for servo system. Used an industrial computer as a core, the instrument had integrated detection with testing and diagnosis as a portable instrument. Through developed and designed for hardware and software, it had extended signal output function for sinusoidal machine; it had adopted the information fusion and data base technique to diagnosis the instrument on-line and off-line. The static position precision of test overland gets 0.1 mil. Application shows it possesses the advantage of simple operate and easy test, high efficiency. It reduces the difficulty of equipment maintenance, conveniences to track and mastery the equipment for long time, and increases the quick guarantee capability. So it has great application value and promotion value.
