Initial corner voltage width manipulation for transmitting information in lighting systems


E.V. Vstavskaya

The wide spread method for power control of lighting sources is the phase control. But this method is not applicable for individual control of lighting sources. The paper proposes a width modulation information encoding method for communication power wires, which is based on the principle of modulating the initial angle of half-cycle voltage. Format of a batch and a single error correction algorithm for the transmission of information is offered and described. The proposed encoding algorithm is implemented in system «FORA – SPI», based on the patent 99913 (Russia) for developing the lighting systems with individual control of lighting sources via power wires.
