The Test And Analysis Of MCV3 Stabilized Gyrocompass

The system of stabilized gyrocompass, which can give the precise information of course and pose for campaign commands and arm systems, is one of main navigational devices for sail and battle. It is also very important for naval ship all over the country. MCV3 Stabilized Gyrocompass was set main research object in this paper. Fault diagnoses and simulation tests were done by using simulation technology of virtual instruments and program-controlled technology to the main circuit boards.First of all, the mathematics model and stabilized circuits were analyzed for the system of stabilized gyrocompass. The realization method of H modulating technology in system was brought out after the theories and characteristics of MCV3 stabilized gyrocompass were explained. Secondly, The main circuits of MCV3 stabilized gyrocompass were analyzed by their functions. The difficulties and innovations of testing for main boards were pointed out. During the testing, a kind of new technology on the form of half automation, inputting by hand and automatic testing made them veracity and reliability. At last, the system construction and application environment for technology of virtual instruments were introduced.The technology of virtual instruments, program control and the expert system of fault diagnose were used during testing circuit boards. The program control of computer made testing veracity and automation high. The results of testing had traceability. In addition, the technology of double buffers for showing dynamic wave was applied. The graphics glittery problem of dynamic showing was resulted. It made dynamic wave more smoothness and stabilization.
