AN EMBEDDED DUAL-SPEED SYNCHRONOUS ACQUISITION RECORDER FOR TRANSIENT SIGNAL

介绍了GPS同步的嵌入式双速暂态信号录波装置的原理、结构及其特点。该装置利用高速采集信号的低速采样智能触发录波 ,获得故障发生时刻的精确波形 ,融合低速采样数据记录系统波形概貌 ,无须大容量存储器和高速CPU即可记录故障全程。采用嵌入式PC 10 4结构 ,既可作为独立录波装置 。

The principles, structure and characteristics of an embedded dual speed GPS synchronous acquisition recorder is described. Precise waveforms when a fault occurs can be obtained by triggering wave recording using low speed sampling intelligence that acquires signals at high speed. By merging the contour of system waveform recorded with the low speed sampling data, the entire process of the fault can be recorded without the need of a large capacity storage and high speed CPU. It can be used not only as an independent recorder, but also as a recording component in the protective unit because of its embedded PC 104 architecture.
