摘要
应用Delphi编程工具对振动测试分析系统进行设计和编程,对PCI2006数据采集卡连续不间断大容量数据采集、显示及存盘的编程技术和虚拟仪器界面设计编程进行了介绍。系统实现了32通道信号数据采集、数据回放、同一窗口内8通道交替信号分析处理、结果分析图形存盘和打印等功能。对信号发生器的正弦信号进行实验,演示和证实系统的测试分析过程。
In this paper a vibration test analysis system is designed and realized based on the Delphi and Virtual technology. The programming technology for PCI2006 A/D card vast continuous data acquisition, graphics display, data storage and the interface design for the virtual instrument are introduced in this paper. Functions of this system such as 32-channels data acquisition, graphics display, data storage, 8-channels alternate signal analysis and processing in a same window, data playback, graphics storage and print come true. Sine waves from two signal generators are measured. Test and analysis of this process are demonstrated and validated.
