军用装备测试性技术发展趋势分析

Development rend analysis of testability technologies for military equipments

近年来,随着军用装备电子化水平和复杂化程度的提高,测试性技术也越来越重要,在理论和应用方面取得显著的进展。对国内外军用装备机内测试技术(BIT)和自动测试设备(ATE)的发展的研究,指出BIT存在的虚警率高、诊断能力不足、诊断模糊等问题,以及ATE存在的费用高、种类多、操作复杂、离线检查等方面的不足,最后在两种技术的结合、总线技术采用、机电BIT技术的发展、虚拟仪器技术的应用和综合诊断等方面分析了测试性技术未来的发展趋势。

In recent years,the testability technologies become ever important because of the enhancing electrification and complexity of the military equipments.The theories and applications of the testability technologies have greatly developed.Firstly,the development of BIT and ATE of military equipments both overseas and interiorly are investigated.Secondly,many problems of BIT and ATE are pointed out,such as the high false alarm rate,inadequate and fuzzy diagnostic ability of BIT,and the high cost,multi-varities,complex operation,and off-line testing of ATE.Finally,the future development trends are analyzed,including the interfuse of the two technologies,the application domain extending to electromechanical system,the wildly application of the bus,the virtual instruments and the integrated fault diagnosis.
