摘要
研究了光纤陀螺捷联惯性导航系统中数据采集单元的设计与实现,系统选用Intel 80C196KC单片机作为系统MCU,利用串口扩展芯片TL16C554实现对三路光纤陀螺信号的数据采集;采用16位高精度模数转换器AD676完成对加速度计信号的数据采集;论文给出了软硬件的实现方案和试验结果;试验结果表明该数据采集装置单元,满足系统的性能要求,有较强的实用价值。
A data acquisition instrument is studied and implemented for the Fiber--optieat--gyro Strapdown Inertial Navigation System （SINS）. Based on the 80C196KC micro--controller unit （MCU）, the data acquisition of the fiber--optical--gyros ls implemented with the Quadruple Asynchronous Communication Element （QACE） chip TL16C554. And a 16--bit high precision AD676 is used for the data acquisition of the accelerorneters. Both the hardware and software design of the data aequisition system is presented. The results show that the data acquisition instrument can meet the requirements for the SINS on data acquirement capability, and has good practieality.
