Demodulation methods for carrier communication signals and photovoltaic power generation systems

Abstract

This invention relates to a demodulation method for carrier communication signals and a photovoltaic power generation system. The demodulation method includes: acquiring a carrier communication signal; sampling the carrier communication signal at a preset dynamic sampling frequency to obtain a sampled signal, the sampled signal including sampled data, the sampled data including a first frequency signal and a second frequency signal, the first frequency signal and the second frequency signal having different frequencies; analyzing the energy in the sampled signal based on an adaptive threshold; and demodulating a logic signal based on the first frequency signal and the second frequency signal. The technical solution of this application can effectively improve the application range of demodulation chips and increase their flexibility of use.
