摘要
介绍自行火炮定位定向导航系统中一种实现轴角-数字转换的设计方案。叙述了多极旋转变压器和旋转变压器/数字转换器AD2S80A的特点、工作原理及其粗精结合方法,给出了基于嵌入式计算机PC/104与AD2S80A芯片实现轴角-数字转换的接口电路与工作时序图,以寻北仪的转位控制为例,说明了该转换方法在自行火炮定位定向导航系统中的具体应用。
This paper provides a scheme of design and realization angle-digital conversion in orienting and positioning navigation system for self-propelled Gun.The feature and principle of multi-pole resolver and resolver-digital converter AD2S80A,the method of combination of coarse and fine axis angle is introduced.The interface circuit and its interface time requirement based on the embedded computer PC/104 and AD2S80A is described.It gives an example of this angle measuring circuit used for moving-control of north-finder.
