技術說明

本發明關於一種單線式訊號控制系統及其方法。此單線式訊號控制方法包括：接收由電源線送來的一交流電壓，其中，交流電壓的每一週期係由一正半波以及一負半波構成之一弦波交流電訊號；根據所欲傳送到負載電路的一數位資料，調整上述弦波交流電訊號的正半波以及負半波，包括：切除上述弦波交流電訊號的正半波與負半波的波形，獲得一相位切除訊號，其中，當數位資料為第一邏輯時，上述相位切除訊號的正半波等於上述相位切除訊號的負半波；當數位資料為第二邏輯時，上述相位切除訊號的正半波不等於上述相位切除訊號的負半波。 An single-wire signal control system and method thereof are provided in the present invention. The single-wire signal control method includes: receiving a AC voltage from a AC power wire, wherein each period of the AC voltage includes a positive half-wave and a negative half-wave to form a sinusoidal AC signal; adjusting the positive half-wave and the negative half-wave of the sinusoidal AC signal according to a digital data to be transmit to a load circuit, which including: removing a first component of the positive half-wave of the sinusoidal AC signal and a second component of the negative half-wave of the sinusoidal AC signal to obtain a phase cutting signal, wherein the positive half-wave of the phase cutting signal is equal to the negative half-wave of the phase cutting signal when the digital data is a first logic, and the positive half-wave of the phase cutting signal is not equal to the negative half-wave of the phase cutting signal when the digital data is a second logic.
