摘要
BIT(built-in-test,也称机内测试、机内自检测)技术作为系统和设备故障检测、定位和隔离的一种手段,对于一些机载设备来说,是一种非常重要的自检方法,主要针对其系统故障,通过其自检的手段改善机载系统的测试性能或者提高设备的诊断能力;目前该种技术的使用频率不管是在国防领域还是在民营领域的系统研制中都很高;该文从机内测试技术的定义、类型、研究现状和展望未来发展趋势这几个方面进行了阐述;总结了大量的文献资料,介绍了BIT应用的功效:投入使用后缩短了设备系统的平均修复时间(MTTR);在战备时期提高了武器装备的完好性,在任务时期提高了任务成功率;另外还能缩减装备维修人员,放宽了对于技术人员的水平要求。总之随着装备复杂程度和技术含量越来越高,BIT技术在维修性和测试性领域占据重要的一席,是该领域的重要研究内容。
BIT(Built-In-Test,also known as machine testing,built-in self testing)technology as a means of detection,fault location and isolation systems and equipment for airborne equipment,it is a very important approach,mainly for the system failure,improve the performance of airborne test system through the means of self or improve diagnostic equipment.At present,the frequency of the use of this technology is very high in both the national defense field and the private sector.This paper from the built-in test technology the definition,types,status quo and Prospect of the future development trend of this a few aspects;summarize the literature,introduces the application of BIT function:put into use to shorten the mean time to repair equipment system(MTTR);in combat time to enhance the weaponry incompleteness in the period,the task to improve mission success rate;also can reduce equipment maintenance personnel,technical personnel for relaxed level requirements.In short,with the increasing complexity and technology content of the equipment,BIT technology plays an important role in the field of maintainability and testability.It is an important research content in this field.
