Embodiment 1
[0029] Such as figure 1 As shown, the power collection module for smart home in this embodiment includes a power supply circuit, a voltage and current detection circuit, a power metering circuit and a data processing circuit. The power supply circuit provides power for the electric energy metering circuit, data processing circuit and drive circuit components. The voltage and current detection circuit converts the measured voltage and current into the signal of the chip input range through the voltage transformer and current transformer as the metering in the electric energy metering circuit. The input of the chip, the metering chip CS5463 receives the digital signal of voltage and current, calculates the power, voltage and current, and outputs the data through the serial port. The data processing chip ATMEGA16L of the data processing circuit receives the power signal output by the power measuring chip, and performs subsequent processing work, including driving the digital tube...
