摘　　要：利用LabVIEWG语言并结合PCI-6024E数据采集卡设计实现了对高速数据的保存与波形再现。这种高速数据流盘充分利用了计算机的存储和与外部设备连接的能力,可以完成多通道数据采集、保存和波形回放,便于数据的保存与波形再现,为后续分析处理数据提供了可靠的依据。硬件系统具有开放性,可以通过修改和增加软件模块来增强和拓展仪器功能。通过仿真实验验证了该仪器能够完成对高速数据的保存和再现,实现理论上所设计的功能。Based on LabVIEW and PCI-6024E Data-Collecting Card, a high-speed data stream instrument is designed to realize data store and waveform reappearing. The instrument makes full use of computer＇s memory power and the capability of connecting with external equipments to achieve multi-channel data acquisition, storing and waveform reappearing; and offering reliable basis for further data analysis and processing. The hardware system of this instrument has the attributes of open, so the functions of the instrument can be enhanced and expanded by changing and increasing software modules. The emulate experiment proves that the instrument is able to complete and reappear the high-speed data, as well as to realize the request of the design.
