中文摘要:

对于雷电流波形检测，硬件触发和软件触发均有可靠性低和波形采集不完整等问题。为此本文根据雷电流的幅度﹑斜率﹑半峰值时间，提出雷电流识别方法和循环触发，来提高触发的可靠性和波形检测的完整性。详细介绍了雷电流在线检测系统的设计与实现，来检测雷电流的波形、幅值、极性、雷击杆塔号及雷击时间等。最后，用C 编写终端上位机，并通过实验验证了检测系统的实用性。

英文摘要:

For the lightning current waveform detection, both hardware trigger and software trigger have low reliability and the incompleteness of the waveform acquisition. According to the amplitude, slope and half peak time of lightning current, this paper proposes the lightning current identification method and cyclic trigger to improve the reliability of trigger and the integrity of the waveform detection. In this paper, the design and implementation of the lightning current online detection system was introduced in detail. It was used to detect the waveform, amplitude, polarity, lightning tower and lightning time etc. Finally, terminal PC was?programmed?in?C ?language, and the practicability of detection system was verified by experiments.
