摘要
军用软件中实时软件的应用越来越多 ,对其可靠性的要求也日益增加。针对实时软件通常与外围设备环境联系紧密的特点 ,分析了测试实时软件的三种基本方法 ,并结合目前国内外仿真测试平台的发展状况以及未来发展前景 ,进一步论证了硬件在回路仿真测试平台解决方案在解决测试实时软件问题中的优势。最后 ,通过分析比较几种常用仿真平台工具的功能特点 ,提出采用RT -Lab仿真工具和QNX实时操作系统 。
The real-time software in the military is used widely, and the reliability of the software needs more and more enhancement. In view of the feature that the real-time software has close ties with the peripheral equipment environment, this paper analyses three basic methods to test the real-time software. The paper demonstrates the advantages in the real-time software testing when the hardware in the loop (HIL) is used in the simulation testing platform. At last, through analyzing and comparing the functions and characteristics of several general simulation platform tools, using RT-Lab simulation tool and QNX real-time operating system, a kind of distributed real-time network simulation testing platform is given.
