Abstract:
1. A method of transmitting and receiving data using a Data Plus (DP) formula in a power line, comprising: (1) transmitting data to be transmitted to a CPU via an interface and converting the data into data of a protocol selected using a program stored in a ROM and a RAM to transmit the data to a mixer; (2) detecting a voltage phase from a power supply to transmit a data transmission time signal according to a phase change and a phase inversion time signal of a transmission data voltage to the mixer via a Schmitt-Trigger circuit; (3) transmitting, by the mixer, the signals transmitted from the steps (1) and (2) to an amplifier according to a transmission time to allow the amplifier to amplify and then transmit the signals to a coil, and transmitting, by a data plus transformer (DPT), the transmitted signals to coils of a power line coil wound n times as an induced current; and (4) allowing a current of the data signals transmitted from the step (3) to flow in condensers of a condenser to receive by coils of a power line coil and then amplifying the current in a filter and amplification interface, transmitting the current to a receiver CPU, restoring a program stored in a receiver ROM and a receiver RAM to an original data signal, and receiving the data signal via an interface or receiving through a condenser of a condenser.
