摘要
提出利用波头较缓、幅值较小的入射电流,通过变换及计算,求出冲击接地电阻的方法,并在此基础上,设计了基于DSP的冲击接地电阻测量装置。该装置采用V/F变换和红外通信技术,实现了信号采集板与主控板之间的信号隔离,有效地提高了系统的抗干扰能力。
This passage propose the method of using slower and smaller amplitude of the incident current,to find the impulse grounding resistance.And on this principle,we designed a set of measurement devices based on DSP.Using V/F transform and infrared communication technology,the measuring device achieved the full separation between the main control board and SAM,effectively improve the system＇s anti-jamming capability.
