摘　　要：针对高压直流局部放电试验缺少可靠的在线数据采集以及保存系统,介绍了一种基于LABVIEW平台的数据测量及分析系统设计方案。系统硬件采用了凌华PCI-9812数据采集卡搭配工业机实现。软件部分则是通过LABVIEW编程实现,整套软件包括数据采集、数据实时保存和数据统计处理三部分。数据采集部分采用两通道同步采样。数据以二进制格式实时保存,可以导入MATLAB中进行各种数据处理,也可以通过数据回放软件特带的功能方便直观的对数据进行研究分析。最后,通过试验验证了该方案的可行性。For the lack of reliable on-line data acquisition and storage system for partial discharge in high voltage DC test,a kind of LABVIEW platform data measurement and analysis system is introduced in this paper. The system adopts the ADLINK PCI- 9812 data acquisition card with industrial machine. The software part is realized by LABVIEW programming,the software includes data acquisition,real-time data storage and data processing. Data collection part adopts two channels synchronous sampling. Data in binary format are stored in real-time,and all kinds of data can be processed in MATLAB,which can also conveniently research and achieve data analysis by using the data playback software with the software. Finally,the feasibility of the scheme is proved by the test.
