Research on Developments of Testability Verification Experimentunder Line Replaceable Module System

摘要:

以外场可更换模块(LRM)为基本组成单元的综合模块化系统已成为现代军用装备电子系统的发展趋势;LRM是装备二级维修保障体系的关键技术之一,其测试性是实施装备二级维修保障体系的关键因素,在LRM的生产定型阶段对其进行测试性验证试验具有很大必要性;目前国内外并没有专门针对LRM体系的测试性验证试验研究;文中对LRM体系下测试性验证试验实施的相关技术研究现状进行了总结,指出了LRM在电气和机械方面的特性对LRM体系下进行测试性验证试验造成的不利影响,并对这一领域进一步研究的关键技术和发展方向进行了展望。

Abstract:

The integrated modular system based on the Line Replaceable Module (LRM) as the basic unit has become the developing trend of the modern military electronic system. LRM is one of the key technologies in two-stage equipment’s maintenance support system, and its testability is the key for the implementation. It is necessary to conduct the testability verification experiment under the LRM in the trial production. The paper summaries updated research status of related technologies of testability verification experiment in LRM system,points out some negative effects on the testability verification experiment of LRM system due to its electrical and mechanical properties.Key technologies and further research in this field are proposed. 
