摘要
介绍了船用捷联惯性导航系统中陀螺仪数据采集系统的设计。该采集系统主要由现场数据采集、双端口 RAM缓存和通讯监听、纠错单元三部分组成 ,采用高性能 16位单片机控制 ,PTS实时发送数据。实测结果表明该系统动态范围宽、精度高 ,很好地解决了捷联惯性系统中对陀螺仪数据实时获取的要求。
The design of gyroscope data acquisition system for marine strapdown inertial navigation system is presented. The whole collection system is made up of three parts: a field data acquisition board, a dual ports RAM buffer unit and a communication monitor and correction unit. The 16 bit microcomputer of high performance controls the system operating process and the gyroscopic conversion data is transferred by PTS mode. Experimental result shows that the collection system has the characteristics of wide dynamic range and high precision, and meets well the requirements of the strapdown inertial navigation system on gyroscopic real time data.
