航天器综合电子系统多维度测试分析

Multi-dimensional testing and analysis of spacecraft avionics

针对开放式、多业务、综合型电子系统的特点,从功能属性、信息流设计、测试流程3个维度对综合电子系统测试进行分析,提出基础服务、安全保障、任务实施3类功能属性,将信息流分解为采集信息流和控制信息流,流程上经历综合电子产品开发测试和多系统对接测试。分析综合电子系统不同维度适用的测试方法,给出功能、信息流测试与测试阶段、测试方法的相互匹配关系,以指导综合电子系统测试实践。

Based on the openness, multi-service and comprehensiveness of electronic systems, the paper analyzes the avionics testing through three dimensions, functional attributes, information flow and test flow. Three types of functional attributes such as basic service, security guarantee and task implementation are proposed, and the information flow is decomposed into collection information flow and control information flow. The test flow goes through integrated electronic product development testing and multi-system docking testing. The testing methods applicable to different dimensions of avionics are then analyzed to give the matching relationships among function, information flow test, test stage and test method, which may guide the practices of avionics testing.
