Control method and control device based on cutdown modulation of power signals

摘要: The invention discloses a control method and device based on cutdown modulation of power signals. is characterized by including steps waveform modulation, carrier transmission drive demodulation. In the step, one-way voltage-stabilizing part in module stranded current loop, signals alternating transmitted cord are modulated, certain section amplitude each cycle cut down to acquire signal. signal terminal along cord. demodulation detection performed module, corresponding information portion read, work state load set according information. According scheme, simple parallel connection series can be used expand expansibility high, cost low.
