双机捷联惯导系统管理软件研究

THE STUDY OF MANAGEMENT SOFTWARE OF TWO MAIN PROCESSOR STRAPDOWN INERTIAL NAVIGATION SYSTEM

本文着重讨论了捷联惯导系统双主机计算机系统结构的管理软件设计与实现问题,给出了完整的管理软件设计方案,对于双主机所特有的资源共享问题做了介绍,引入命令信箱概念来实现两主机之间的命令传递。同时,本文管理软件还包含了在实际地面测试时,实现捷联系统计算机与地面PC机的通讯功能。本文管理软件的另一大特点是运用了PL/M-86与ASM-86,Turbo C与MASM的混合语言编程技巧,充分发挥了各种语言的优点。本文的管理软件已在实际系统中应用。

The paper mainly discusses the design and implement of Strapdown Inertial Navigation System (SINS) which has two main processors, gives the whole scheme of software design,introduces the problem of sharing resource and the concept of command box used in the two main processors, and also the management software includes the communication software between SINS's computer and PC used for testing. The management software has another original view in using mixed programming language between ASM-86 and PL/M-86, and between Turbo C and MASM. The management software has been used in a practical system.
