Study On Residential Smart Plug Based On Ethernet Remote Control

As global IoT and energy pollution issue become more and moreprominent, therefore something build Ethernet communication andpower measurement function into one device is creative idea, smart plugto be what you want. Hereby we fully utilize the high performance32BitMCU who have multi-channel A/D input and mega-Hz above CPU processability to achieve power energy calculation function, as well as realizepower quality analysis by using software algorithm like FFT, LagrangeInterpolation to replace original H/W component, we would put someresearch to verify its performance and feasibility.In this project, we will introduce the each step like sampling method,V/I phase compensation, IIR low-pass filter and FFT algorithm how towork and how to ensure the minimal tolerance.The overall system including Web App, smart plug and collaborationequipment. Via Matlab, Renesas HEW and HS-3303to check each itemlike metrology accuracy, Ethernet communication stability etc, spot andcontrol the tolerance generation, to prove the system design is correct.
