闭环光纤陀螺数字检测电路的集成化

Integration of Digital Detecting Circuit for Closed Loop FOG

集成化、数字化是光纤陀螺的发展趋势，也是光纤陀螺进入实用化、批生产化的关键．鉴于国内光纤陀螺的发展状况及半导体工艺水平的限制，以高速数字信号处理芯片（ＤＳＰ） 及大规模可编程逻辑器件为基础，对闭环光纤陀螺的数字检测电路的集成和优化进行了研究．测试结果表明：采用集成化设计的光纤陀螺检测电路在性能及可靠性上比分立元件构成的检测电路均有提高和改善．

Integration and digitalization are two key factors leading to the engineering application and batch manufacturing of FOG. By considering the FOG's technical situation and the technique of semiconductor in our country,the research on integration and optimization of digital detecting circuit for the closed loop FOG based on the fast DSP chips and large scale CPLD or FPGA chips is presented in this paper. Test result shows: the performance and reliability of integrated detecting circuit are improved as compared with the circuit based on the separated components.
