POWER METER BASED ON SYSTEM ON CHIP
First Claim
1. A power meter based on a system-on-a-chip (SoC), comprising:
- an analog-to-digital 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 the digital data from the analog-to-digital converter;
a micro controller unit processing power meter information using data from the digital signal processor;
a memory storing the power meter information processed by the micro controller unit; 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,wherein the micro controller unit controls and manages the digital signal processor, memory and interfaces, and additionally classifies the power meter information into objects with common properties, assigns identification numbers to the objects, and stores the power meter information in the memory for management and processing.

Abstract
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.
