基于PXI虚拟仪器的机械工程测试系统开发

为适应机械设备研制、开发、应用和教学过程中越来越复杂的测试系统,本文以PXI虚拟仪器为平台,采用模块化结构对系统进行组建设计,从底层开发出完成基本测试与控制功能的机械工程测试系统。可以进行信号采集、滤波、信号显示、时域分析、频域分析、信号的保存、备份、生成试验报告和读取数据等,利用开发的测试系统完成应变、位移、压力、流量和温度测试试验。在系统的总体设计中,建立数据库对数据进行存储、管理和查询。本文充分利用PXI虚拟仪器的标准化系统资源,开发了便于更新、机动灵活、成本低廉、中文界面的机械工程测试系统,提高了测试的综合应用效率,为机械工程测试领域提供了优质的测试系统。
