为了提高机载计算机外场检测和维护水平,选用COTS产品,研制了便携式机载计算机外场测试仪。在介绍测试仪需求的基础上,重点从硬件和软件两个方面介绍了测试仪的设计方法,详细叙述了为满足恶劣环境要求进行的适应性改进。测试仪设计先进,自动化程度高,具有模块化、层次化和开放式的特点,便于维护和升级,为机载计算机在外场恶劣环境下提供了便捷、有效的综合测试手段。
In order to improve the level of airborne computer field detection and maintenance, the COTS product was selected and a portable airborne computer field tester was developed. On the basis of introducing the requirement of tester, this paper introduces the design method of tester from the aspects of hardware and software, and narrates the adaptability improvement to meet the harsh environment requirements. Tester advanced design, high degree of automation, modular, hierarchical and open features, easy to maintain and upgrade for the airborne computer in the harsh environment provides a convenient and effective means of comprehensive testing.
