摘要

摘要: 多通道高速数据采集软件面临：被测信号多样化，通道设置及管理难度大；传输数据并发量大，传输稳定性和瞬时传输速度要求高；测量数据量大，后处理及速度快；实验数据重要性高，测试软件必须稳定可靠的挑战。软件采用模块化+图形化设计，使用SCPI命令对设备及通道进行设置；测试了75台示波器同时上传数据的传输速度；对比了LabVIEW波形显示和GDI+波形绘制的区别；完成了上位机故障情况下数据获取功能设计。结果表明：该数据采集软件可完成75台示波器的管理，实现300通道数据的上传、处理、显示、存储。100 kpts存储深度300通道数据上传时间为9.7 s，300通道波形刷新时间为0.91 s。

Abstract: Multichannel high-speed data acquisition software is facing the following difficulties: complexity in setup and management of signal multichannel; The concurrent transmission of data requires high stability and instantaneous transmission speed; High-speed post-processing and high-speed waveform display are required for large amount of measurement data; The test software must be stable and reliable to meet the important requirements of experimental data. The software uses modular graphical design and SCPI to complete channel setup. The transmission speed of data uploaded simultaneously by 75 oscilloscopes was tested. The differences between LabView waveform display and GDI+ waveform drawing are compared. Data acquisition function in case of software failure is designed. It is shown that the data acquisition software can manage 75 oscilloscopes and upload, process, display and store 300 channels of data. 100 kpts memory 300 channel data upload time is 9.7s, 300 channel waveform refresh time is 0.91 s.
