Design and Implementation of the System for Remote Voltage Harmonic Monitor

摘要

Take 8-bit microcontroller (C8051F005) as the nucleus and study a kind of voltage harmonic monitor device that satisfies the long-range monitor. The harmonic analysis algorithm adopts Fast Fourier Transform (FFT). This device has two work modes: "native" and "remote". It also can communicate with monitor center through telephone line, serial port, IC card, PDA (Personal Digital Assistant), etc.
