Aircraft Electric Power Source Test System Based on LabVIEW and DIAdem

摘要:

试验环节是产品研制生命周期中的重要环节,但是一直以来都缺乏有效的管理手段,在整个测试阶段都存在大量的人为的、重复性的工作,导致试验效率低下,为改善这一现状,提高试验效率,提出了一种基于PXIe数据采集系统,借助LabVIEW和DIAdem软件的测试系统解决方案:以LabVIEW控制数据高速同步采集,DIAdem调用LabVIEW模块执行算法分析,通过软件集成,实现对测试系统的全面管理,包括数据采集、数据检索、数据分析、报表生成及整个流程的自动化控制；以C919飞机电源测试系统为介绍对象,对该套测试系统解决方案进行阐述,实际测试情况表明,在数据吞吐率大于200 M/s的情况下,相对传统测试方法,该测试方案在保证测试精度的基础上,极大的提高了试验效率,极大的提高了系统的可扩展性和可维护性。

Abstract:

The Test process is an important link in the product development cycle,however,there has been the lack of effective management,throughout the testing phase,there exists a lot of artificial,repetitive work which lead to low test efficiency.For the purpose of improve efficiency,an advanced test solution is put forward based on PXIe data acquisition system by hardware,LabVIEW and DIAdem by software:LabVIEW takes control of high speed synchronous data acquisition;DIAdem calls the data analysis function compiled by LabVIEW to accomplish the integration of data acquisition、data playback、data analysis、report generation and the automation of links above.In this paper,the C919 power supply test system is introduced to describe the solution,the test results show that,in the case data throughput is greater than 200M/s,this solution improves test efficiency、system scalability、system maintainability greatly,while accuracy is guaranteed.
