FIELD: information transmission systems.

SUBSTANCE: invention relates to systems for transmitting information over alternating current power supply lines and is intended for remote control of the operating modes of electricity consumers connected to the power supply line, namely LED lamps. A method for addressing information transmission over an AC power supply line, assuming the information transmission consisting of an address field and a data field limited by markers over an AC line. The information is transmitted via a transmitter at the beginning of the line with the possibility of interrupting the supply voltage for a time equal to half a period of the fundamental harmonic, with the beginning at the point of transition of the fundamental harmonic through zero. The information is received by receivers that capture interruptions in the supply voltage and are located along the alternating current line. The transmitter contains a sensor for transitions of the positive half-wave of the supply voltage through zero, a switching device for the positive half-wave of the supply voltage, controlled by a microprocessor, a sensor for transitions of the negative half-wave of the supply voltage through zero and a switching device for the negative half-wave of the supply voltage, controlled by a microprocessor. Each receiver has its own number and contains a sensor for transitions of the positive half-wave of the supply voltage through zero, a sensor for transitions of the negative half-wave of the supply voltage through zero, and a counter of periods of the supply voltage. At the beginning of information transmission, the switching device for the positive half-wave of the supply voltage interrupts the positive half-wave of the supply voltage, then a whole number of periods of the supply voltage follows, corresponding to a predetermined control command. When the next negative half-wave of the supply voltage passes through zero, the switching device for the negative half-wave of the supply voltage interrupts negative half-wave of the supply voltage, then the number of periods of the supply voltage corresponding to the receiver identifier follows. When the next negative half-wave of the supply voltage passes through zero, the switching device for the negative half-wave of the supply voltage interrupts the negative half-wave of the supply voltage, in each receiver the moment of interruption of the positive half-wave of the supply voltage is determined, based on the absence of pulses coming from the sensor of transitions of the positive half-wave of the supply voltage through zero, using a counter of periods of the supply voltage. The number of whole periods of the supply voltage is counted until the interruption of the negative half-wave. The control command is recorded and the counting of periods of the supply voltage begins until the interruption of the negative half-wave of the supply is detected again voltage. The receiver identifier is fixed and the receiver control command with the corresponding identifier is executed.

EFFECT: increasing the reliability of information transmission and simplifying the method.
