Abstract :
A data acquisition system of three-axis integrative fiber optic gyroscope is studied and implemented in this paper. The hardware platform of the system is composed by 32-bit fixed-point digital signal processor TMS320F2812 and high-precision ADC is used to acquire the signals of optical fiber gyroscope in three orthogonal axises. The designs of the system hardware and corresponding software, including data acquisition module, data processing module, communication module and so on, are presented in detail. The tested results show that the system can meet the requirement of high-mobility SINS depended on its excellent performance in accuracy, timeliness and sampling synchronization.
