摘要:
介绍了中国首次火星探测任务有效载荷分系统的试验矩阵,以及地面综合测试系统的技术要求。面向2个探测器、5种场景的测试任务需求,设计由接口适配、业务处理、数据管理组成的3层统一架构,实现了不同场景下测试系统的功能和外部接口适配;根据星上科学数据处理与传输机制,设计地面科学数据处理流程,满足了13类载荷科学数据判读需求;针对单星1 900维工程遥测、400条数据注入指令的高维特性,设计基于规则的数据判读软件,实现了载荷遥测数据及数据注入指令的自动化判读。任务执行结果表明该系统满足不同试验模式下有效载荷测试任务的需求,有效保障了载荷测试任务的顺利实施。

Abstract:
Test matrix of payload subsystem for first Mars exploration Mission in China and technical requirements of integrated testing system are introduced. In view of requirements of testing tasks for 2 spacecraft and 5 testing scenes,3 layers of unified architecture composed of interface adaptation,business processing and data management are designed,which helps testing system achieve the adaption of external interface and functions for different testing scenes. According to payload scientific data processing and transmission mechanism on orbit,scientific data processing flow is designed for the testing system,which meets different requirements for 13 kinds of payloads. According to the high dimension characteristics of 1 900 dimension engineering telemetry parameters and 400 data injection instructions,the software based on rules for automatic data discrimination is designed,which makes all parameters and data injection instructions can be checked intelligently. The task execution results show that the system meets the needs of payload testing tasks under different modes,and effectively ensures the smooth implementation of payload test tasks.
