摘要
基于虚拟仪器技术对数据采集系统进行完整设计与实现,阐明数据采集系统的硬件开发,尤其是系统信号SPD保护器的硬件研制。讲述了基于LABVIEW的软件开发,其中,数据的采集、报警分析、存储与回放是编程的关键点。实验结果表明,本系统可以很好地对稳态信号和频率小于20kHz的放电脉冲的波形信息进行准确的采集、分析和处理。
This paper introduces a data acquisition system （DAQ） design and realization based on virtual instrument （VI）. And the development of system hardware especially SPD is expatiated upon. Development of software based on LABVIEW is described. It＇s of great importance to program for data acquisition, alarm analysis, data storage and replay. Experiment results show that the system is effective to collect, analyze and process data for steady signal and pulse signal whose frequency is less than 20kHz.
