Design and realization of network test system for inertial instrument

To increase the application accuracy of the inertia instrument, a distributed network test system for inertial instrument is designed and realized, on the base of analyzed the test contents, test parameters, network architecture, and network test mode. The system has four layers composite architecture based on C/S/B network model. The scheme of automatic test based on VXI bus was adopted in the field test unit. The Ethernet was selected as bottom level test network. The network communication technology based on TCP/IP was adopted in programming. Remote distributed test of inertial instrument, issues of test information, remote analyses of performance and remote manage of information are realized. The results of the practical use indicate that the system supplies a reliable hardware platform for remote fault diagnosis, remote expert guide and decision of inertial platform.
