提出一种电压波形压缩记录技术。该技术基于“点相似”的数据处理方法,实时处理高速采样所得数据,对点相似的数据进行压缩,波形片段的等值频率越低,数据压缩效果越好。文章通过实测数据说明了压缩效果和波形复现效果,证明在应用该压缩存储技术后,记录设备存储容量的利用率提高了上千倍,这使得记录持续时间长并带有很高频率分量的暂态电压波形成为可能。该技术特别适用于波形等值频率随时间变化较大的情况,压缩存储技术也大幅度减轻了后期数据的处理量,并明显改善了测量仪器的显示效果。 Proposed a voltage waveform compression recording technology. The technique is based on the “point-like” data processing method, real-time processing of high-speed sampling data, similar points of data compression, the lower the equivalent frequency of waveform fragments, the better the data compression. The article illustrates the compression effect and the waveform reproduction effect through the measured data, and proves that after the application of the compression storage technology, the utilization rate of the storage capacity of the recording device has increased thousands of times, which makes the recording lasting for a long time with a high frequency component Transient voltage waveforms are possible. The technology is particularly suitable for waveform equivalent frequency changes over time, the compression storage technology has also greatly reduced the amount of post-processing capacity and significantly improved the display of measuring instruments.
