摘要： Power meter based on a system-on-a-chip (SoC) is disclosed. The power meter provides all necessary functions related to power metering, power information processing and power information transmission on the basis of a system-on-a-chip enabling power meter functions to be mounted in a single chip in a manner that hardware resources can be recombined to implement hardware logics ensuring portability according to customer needs. The SoC-based power meter includes: an A/D converter converting an analog signal corresponding to a voltage and current supplied to a customer into digital data; a digital signal processor performing power metering by processing digital data from the A/D converter; a micro controller unit processing power meter information using data from the digital signal processor; a memory storing processed power meter information; and interfaces sending power meter information stored in the memory to external appliances, and forwarding signals received from external appliances to the micro controller unit.
