空间站综合仪器系统架构设计

以计算机技术为核心的空间站综合仪器系统,是空间微重力环境下提供生物化学、电子学、材料学等科学实验条件的功能作业平台。受限于空间极端环境,相对于常规自动测试系统,其在可靠性、互换性、可维护性、智能性、灵敏度、功耗与结构等方面的要求更为严苛。针对空间站综合实验仪器的应用需求,为重点实现系统通用化与开放性,设计了一种以ATML为信息交互标准、以VPX为通信控制主干的集中式/分布式系统架构。该架构满足系统的通用化、灵活性和高可靠性需求,具备较强的可行性。

An Architecture of Comprehensive Experimental System in Space Station

With computer technology at the core, comprehensive experimental system in space station is a multi-functional experiment platform which provides experimental conditions for biochemistry, electronics, material science and so on, under low gravity environment. Limited by extreme environments, it has to meet more stringent requirements in the aspects of reliability, interchangeability, maintainability, intelligent, sensitivity, and structure. To satisfy the requirements needed by comprehensive experimental system in space station, this paper mainly aims to the generalization and openness of the system and designs a centralized/distributed system architecture which is based on VPX and adopts ATML as the test information standard. This design has the potential to meet the requirements of generalization, fl exibility, and reliability.
