AC Multi-channel AC Watt Hour Meter waveform storage device using lossy compression technology

摘要

The present invention discloses a multi-channel AC power meter waveform storage device using lossy compression technology. The multi-channel AC watt-hour meter waveform storage device of the present invention uses an input unit that receives the AC voltage and power waveforms measured from the AC watt-hour meter, and a loss compression technique to convert AC voltage and current waveforms, which are curved waveforms according to the sampling frequency, into stepped waveforms. And a control unit that converts and controls the converted stepwise waveform to be stored.
