惯性组合导航系统接口子系统的设计与实现

介绍了某型无人机捷联惯性/卫星组合导航系统接口子系统的设计与实现的思路,给出了接口子系统的原理实现框图。对数据通信过程中使用的通信协议做出了详细介绍,同时,举例讲解了如何将需要传输的物理量转化为所需要的通信数据的方法。本文着重介绍了ARINC429通信接口板的软件设计思路和程序编码的过程,在此基础上完成了接口子系统的软件设计,进行了大量的数据传输测试,测试结果表明系统的设计是成功的。

An approach has been presented,which is about the desig n and implementation of the interface subsys-tem of a basic strapdown inertial integ rated navig ation system.The implementation of principle chart has been g iven.The communication protocols used in data communication have been introduced carefully.For example,the method has been presented,which is about how to convert the physical parameters to the special com-munication data.The software desig n ideas and process has been emphasized.And then the software desig n of the interface subsystem has been finished.The results of actual usag e show that the desig n of the inter-face subsystem is successful.
