摘　　要：随着C919等大型飞机的出现,测试系统对机载实时处理系统提出了更高的技术要求;机载网络数据实时处理系统采用实时性较强的vxWorks开发环境,通过合理调配各个功能模块之间的资源,即合理分配线程来实时的完成所有功能;经过科研试飞验证,该系统具备3 000个参数的实时处理能力,系统运行稳定可扩展性强,满足目前大飞机机上测试系统数据实时处理任务的要求,对保障大飞机试飞科目的顺利进行具有积极的意义。With the arrival of large aircraft such as C919, test system puts forward higher technical requirements for airborne real--time processing system. The real--time processing system of airborne network data adopts vxWorks development environment with strong real-- time. Through allocates of resources rationally between the functional modules, that is, allocates of threads rationally to complete all func- tional modules real--time. Verified by scientific research in flight test, the system has real--time processing capability of 3 000 parameters. The system is stable and extensible, and meets the requirements of real--time data processing tasks for large aircraft airborne test system. It has positive significance for ensuring the smooth going of subjects test for large aircraft.
