摘　　要：提出了一种基于”仿真软件＋中间件”的接15／仿真系统通用软件架构。开发了Interface_RTI中间件，使用XML文件作为系统配置文件，无需重新编译Interface_RTI中间件程序就可以支持在不同系统上的仿真运行，降低了软件维护成本。对仿真软件进行了合理的任务划分和优先级设置，减少了任务调度开销，保证了软件实时性。该软件能满足某型UAV航电系统的接口仿真功能、性能、通用性、可靠性及灵活性要求。The paper proposes a kind of universal software architecture of interface simulation system, which is based on middle- ware for the simulation software. By using XML as the format of the system configuration file in the development of Interface_RTI middleware, it can support the simulation running in the diverse systems without re-compiling any Interface_RTI middleware program so as to reduce the cost of software maintenance. The reasonable task dividing and the priority setting of the simulation software are conducted, which reduces the task scheduling overheads to ensure the software instantaneity. The software can satisfy the require- ments of the interface simulation functions, performances, universality, reliability and flexibility of a certain UAV avionics.
