基于Compact PCI总线的姿态角数据采集卡设计

Design of Attitude Angle Data Acquisition Card Based on Compact PCI Bus

阐述了轴角数字转换的基本原理,设计了姿态角数据采集卡硬件,编写了采集卡驱动程序,研究了双通道轴角粗精组合及纠错算法,最后通过与75SD1采集卡进行了对比测试,结果表明,姿态角数据采集卡工作稳定,数据准确可靠,满足海军舰艇导航装备检测要求。

The basic principle of resolver to digital conversion was introduced. Hardware of attitude angle data acquisition card was de signed. The driver of the acquisition card was developed. Combination of coarse and fine code and error-correcting algorithm was studied. In the end, through the test compared with 75SD1 acquisition card, it turned out that the attitude angle data acquisition card works well with ac curate and reliable data and meets the test demand of navigation equipment on naval ship.
