Abstract
For the limitation of the primary data acquisition card of laser gyroscope SINS, based on the further analysis of the features of output signals of laser gyroscope and accelerator, this paper has finished the design of data acquisition card according to FPGA, which is described by VHDL. This design of data acquisition card is faced to PC/104 system. The experiments show that this acquisition card counts numbers real-timely and exactly, and can achieve the counting effect of primary acquisition card completely; taking PC/104 system simplifies the devices at a large extend so that it also improves its simplification for using and flexibility for collocation.
