Watt-hour meter |
摘要 |
<p>In a watt-hour meter, encoders 116, 117, 118 and 119 respectively convert a signal concerning a current and voltage used by a customer into a code sequence signal by Reed-Solomon codes or convolutional codes. Decoders 121, 122, 123, and 124 reversely convert the code sequence signal to the signal concerning the current and voltage. A power calculating section 125 converts the signal concerning the current and voltage into data concerning electricity consumption.</p> |
