航天器有效载荷分布式测试系统设计与实现

Design and realization of spacecraft payloads distributed testing system

随着航天器有效载荷种类、功能及结构日趋复杂，对集成仿真测试系统的性能要求也越来越高。在分布式高性能计算机网络体系结构基础上，融合“面向对象构件化、订制化”和“强内聚、松耦合”的先进设计思想，结合智能接口控制文档数据库结构，设计了一套面向用户订制式的有效载荷集成仿真测试系统，具有较强的智能性、可靠性、适应性和可扩展能力，通过灵活配置实现了系统动态重构。该系统已成功支持了多个航天型号任务中有效载荷的集成测试，实践表明：系统运行稳定可靠，研制周期大大缩短，开发成本有效降低。

With the types, functions and structures of spacecraft payloads increasingly complex, the requirements for the performance of integrated test system are getting higher and higher. A spacecraft payloads integrated test system with the configuration of customized user-oriented function is realized in this paper. The system is based on distributed high-performance computer network architecture, in compliance with the advanceddesign concept of object-oriented componentization and customization and strong cohesion and loose coupling, and in combination withdatabase structure of intelligent interface control documents. The system has higher reliability, adaptability and scalability, and the system dynamic reconfiguration is realized by flexible configuration. The system has successfully been usd for the payload integrated tests in multiple aerospace model tasks, which prove that the system is stable and reliable, the development cycle is greatly shortened and the development cost is effectively reduced.
