The design of fault diagnosis system for platform gyrocompass computer based on FPGA

For platform gyrocompass computer,the conventional detection method is difficult to detect the failures in time.For this reason,we propose a design method for the platform compass computer based on field programmable gate array(FPGA),which can automatically detect the platform gyrocompass computer and determine the locations of failures.Meanwhile,the design scheme of software and hardware for the fault diagnosis system is given.The principle of simulation circuit for resolvers is illustrated in detail.Finally,the ways of signal acquisition and data processing of this system are also given.
