Research on the integrated detection technology of the new type of airborne electromechanical management system

摘要:

针对现代飞机高集成度机电管理系统的测试与仿真需求,提出一种基于PXI技术的新型机电管理系统综合检测系统设计与实现方案。在该方案中，机电管理系统的所有信号经过信号接口盒后进入到综合检测系统中，通过断点模块连接机电管理系统产品，在断点模块可以对综合检测系统的所有信号进行监控测试、信号验证及分析处理；通过硬线、RS422总线、GJB289A总线、ARINC429总线形式将机电管理系统和机电管理系统综合检测系统相连接。该系统可有效节省硬件资源、准确实现信号级故障隔离,可实现机电管理系统硬件和软件的独立检测并且可实现多台机电管理系统的测试和检验；与传统手动检测相比,可以平均节省60%的检测时间。通过测试和试验,机电管理系统综合检测系统工作稳定、可靠。

Abstract:

For modern aircraft high integration test and simulation of electromechanical management system requirements, in this paper, a new type of electromechanical management system based on PXI technology integrated test system design and implementation scheme. The system can effectively save the hardware resources, accurately realize the signal level fault isolation, which can realize the electromechanical management system software and hardware independent testing and can realize many sets of electromechanical management system of testing and inspection;Compared with the traditional manual detection, can save an average of 60% of testing time.Through test and experiment, and electromechanical management system integrated test system is stable, reliable work.
