Missile Servomechanism Test System Based on PXI Bus

According to the situation of present missile servomechanism testing,a scheme of an automatic test system based on virtual instrument (VI) is suggested.Test technology based on bus used in measurement system of missile servomechanism is discussed as well.Based on VI and PXI bus,a servomechanism test system with high credibility,high precision and self-diagnosis capacity,is built up.The system can be used in universal test and its software is easy to be replanted and extended.Combined with network,the system provides the function of remote monitoring and diagnosis,witch has many benefits to system maintenance.Upon testified,the system can be used to test different servomechanisms.
