航天飞机的计算机综合系统为航天飞机的轨道控制系统提供数据处理能力。它完成制导、导航和控制、有效载荷的操纵和管理以及实现监视功能等所必须的数据处理。它由五个彼此连结而又独立的通用计算机构成。用它们来满足全部电子设备的容错、功能划分和功能隔离的需要。每个通用计算机由中央处理器和输入/输出处理器组成。用前者来完成与应用程序有关的全部计算;用后者控制航天飞机的其他子系统与计算机之间的信息传递。本文讨论了航天飞机计算机综合系统的功能、特性、机械性能及操作。
The shuttle’s computer integrated system provides the spacecraft’s orbit control system with data processing capabilities. It completes the data processing necessary for guidance, navigation and control, payload handling and management, and monitoring functions. It consists of five interconnected and independent general purpose computers. Use them to meet the needs of all electronic equipment, fault tolerance, functional separation and functional isolation. Each general purpose computer consists of a central processing unit and an input / output processor. With the former to complete the application-related calculations; the latter to control the space shuttle between the other subsystems and computer information transfer. This article discusses the functions, features, mechanical properties, and operation of the shuttle integrated computer system.
