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。 This article focuses on the SINS dual-host computer system management software design and implementation of the problem, gives a complete management software design, dual host-specific resource sharing is introduced, the introduction of the concept of command mail Achieve the order transfer between the two hosts. At the same time, the management software of this article also includes the communication function of the strapdown system computer and the ground PC in the actual ground test. Another great feature of this article is the use of mixed-language programming techniques between PL / M-86 and ASM-86, Turbo C and MASM to give full play to the advantages of various languages. This article management software has been applied in the actual system.
