| 发明名称 | Data transmission method and device for A/C systems | ||
| 摘要 | A method for modulating the effective power in one or several power consuming devices disposed in an A/C system in order to transmit data on a power supply line thereof by specifically varying the effective power in the connected device. In order to transmit the data, the momentary value of the effective power is randomly varied (increased or decreased), and the data is impressed into the A/C supply line by a unit (transmitter or modulator) and is evaluated by another unit (receiver or demodulator). | ||

| 主权项 | 1. A method for modulating the effective power in one or more power consuming devices disposed in an A/C-power supply network having a power supply line by at least one modulator in order to provide transmission of data via the power supply line, comprising the step of specifically varying exclusively the effective power on the power supply line via a DC voltage source when the one or more power consuming devices are connected to and receiving power from the power supply line during a period of time when the one or more power consuming devices are not receiving A/C power from the power supply line, wherein only the instantaneous amount of said effective power is altered, in order to effect the transmission of the data. | ||
