阐述了8通道高速大容量数据采集分析系统的硬件集成、操作控制及波形分析程序设计。在1997年甘肃平凉人工引雷试验中首次取得了微秒量级的闪电放电电流、电场变化、磁场等参量的同步资料。利用该系统还可对记录的闪电波形进行分析和多种信号处理。

In this paper, the hardware constitute and the design of controlling and analyzing program of a multi-channel high sampling and long record system data acquiring and analyzing are described. The synchronous data of current, electric field change, dE/dt and magnetic field et al with the order of microsecond are firstly acquired by using this system during artificially triggered lightning experiment carried in Pingliang country, Gansu on July 1997. Using this system, the measured lightning waveform can be analyzed and carried out multi signal deal.
