摘　　要：针对捷联惯怀系统中陀螺仪的动态测量范围很宽的要求，设计了一种高精度，宽量程的数据采集器，该系统由采集板，多功能板和通讯监听、纠错单元三部分组 用双口ＲＡＭ实现现场数据采集与远程导航计算机的高速通讯，可靠性好，解决了捷联惯性系统中数据采集传输与姿态运算的时间冲突问题。This paper discusses a kind of data acquisition system with high precision and large dynamic measurement range for the strapdown gyroscope. The converter is made up of three parts: acquisition board, multifunction board and communication monitor and correction unit. Dual ports RAM is used to realize high speed and reliable communication between the acquisition board and the remote navigation computer. This converter resolves the conflict of remote data transmission and time consuming attitude calculation.
