基于资源共享的分布式机载软件测试系统设计

随着装备软件系统的发展，越来越多的硬件功能软件化，装备软件的发展朝着高综合、高集成、一体化的趋势发展。目前航空航天装备软件中，嵌入式软件占据主导地位，相较通用计算机软件，嵌入式软件的测试具有面向特定应用，有实时操作系统支持，运行芯片和平台较为固定，并且需要特定的数字总线资源进行数据注入等特点。尤其对于复杂的，高度综合化模块架构的嵌入式软件系统软件测试，对于测试和验证系统的要求也越来越高，数据采集、数据记录、数据激励、数据监控、数据分析等各种测试和验证系统的需求也使得综合化软件测试验证系统结构越来越复杂，基于分布式架构的软件测试系统已经成为必然趋势。结合嵌入式综合化软件测试系统的功能要求以及测试系统的特点，提出了一种基于对等架构下的分布式测试系统设计，该设计不仅能够满足嵌入式软件运行平台规模的扩展，也能够在分布式架构下实现软件运行平台内部资源的共享。

Design of Distributed Airborne Software Testing System Based on Resource Sharing

With the development of equipment software systems,more and more hardware functions are becoming software oriented.The development of embedded software is moving towards a trend of high comprehensiveness,high integration,and integration.Currently,embedded software dominates in aerospace equipment software.Compared with general computer software,embedded software testing has the characteristics of being specific to specific applications,having real time operating system support,running chips and platforms that are relatively fixed,and requiring specific digital bus resources for data injection.Especially for software testing of complex and highly integrated modular architecture embedded software system,the requirements for testing and verification systems are also increasing.The requirements for various testing and verification systems such as data collection,data recording,data stimulation,data monitoring,and data analysis also make the structure of integrated software testing and verification systems increasingly complex.Software testing systems based on distributed architecture have become an inevitable trend.This article proposes a distributed testing system design based on peer to peer architecture,combining the functional requirements of embedded integrated software testing systems and the characteristics of testing systems.This design can not only meet the expansion of the scale of embedded software running platforms,but also achieve the sharing of internal resources of software running platforms in a distributed architecture.
