为了实现装备检测点信号的本地和远程测量,设计开发了一种基于PXI总线的装备检测终端。系统的信号采集采用了PXI体系结构的硬件实现,系统软件采用Lab VIEW平台开发,远程检测采用Data Socket技术和远程面板技术实现。测试结果表明,装备检测终端实现了测试点的本地测量和存储、信号发生器等功能,通过网络实现了远程示波器和频谱仪功能。

To achieve local and remote measurement of equipment detection-point signals, a kind of equipment detection terminal is designed and developed, which is based on PXI bus. PXI architecture of virtual instrument is applied to the system＇s signal acquisition module. System software is developed by LabVIEW platform. DataSocket technology and remote panel technology are employed to implement remote detection. Testing result shows that equipment detection terminal has functions of local measurement of detection point, storage and signal generator, and performs the functions of remote oscilloscope and spectrometer by network.
