摘要： A method and apparatus for data transfer over existing or newly installed residential or commercial power lines is comprised of a transmitter and receiver unidirectionally communicating by phase cutting a portion of the received carrier voltage supply so as to receive a digital signal of low bandwidth. The resulting communication method is known as phase cut carrier, or PCC. The phase cut carrier communication method is shown to be able to addressably communicate lighting level commands for various types of lighting. In other embodiments, the phase cut carrier method may be used to control the powered status of addressably or nonaddressably controlled equipment.

摘要： A system and method for providing full-duplex data communications between an electric power distribution station and a power consumer via the power distribution line providing electric power is provided. A first information transmitter, coupled to the power distribution circuit, provides first information signals concurrently with the power signal to the power consumer via the power distribution line. A first information receiver, coupled to a power consumer device powered by the electrical power signal, receives the first information signals via the electric power distribution line. A second information transmitter coupled to the power consumer device provides second information signals concurrently with the electrical power signal. A second information receiver, coupled to the power distribution circuit, receives the second information signals via the electric power distribution line. The information signals transmitted on the power distribution line can be transmitted at a frequency lower than the frequency of the transmitted power signal.

摘要： A communication system uses the current waveform of an electricity distribution network as a carrier, the signal being present as current pulses around four predetermined zero crossings. The current waveform is sampled around the voltage zero crossings to obtain a time-ordered set of waveform values. The ordered waveform values for each bit are examined to determine if the values fall within preset criteria indicative of a stable carrier. When the ordered waveform values for a particular bit all fall within the preset criteria, that particular bit is identified as a good bit. When at least some of the ordered waveform values for a particular bit fall outside the preset criteria, that particular bit is labelled as suspect. The ordered values of each suspect bit and of adjacent bits are tested to determine whether four successive values meets the preset stability criteria, and whether the four successive values indicating a stable carrier include at least two succesive values from the suspect bit. If the carrier stability test is passed, the binary value of the suspect bit is based upon the successive carrier stability indicating values from the suspect bit. Otherwise the suspect bit is labelled as uncorrectable.
摘要翻译：通信系统使用配电网络的电流波形作为载波，该信号作为围绕四个预定过零点的电流脉冲存在。电流波形在电压过零点周围进行采样，以获得时间有序的波形值集合。检查每个位的有序波形值，以确定值是否落在指示稳定载波的预设标准内。当特定位的有序波形值全部落在预设标准内时，该特定位被识别为好位。当特定位的有序波形值的至少一些值超出预设标准时，该特定位被标记为可疑。测试每个可疑位和相邻位的有序值以确定四个连续值是否满足预设的稳定性标准，以及指示稳定载波的四个连续值是否包括来自可疑位的至少两个连续值。如果载波稳定性测试通过，则可疑位的二进制值基于来自可疑位的连续载波稳定性指示值。否则可疑位被标记为不可校正。

摘要： A transmitter (12) has an output (13) adapted to be connected across an alternating current power line (AC1, AC2) at a point remote from an appliance (24) to be controlled. The transmitter generates one pulse per cycle of the alternating current. The pulse phase has a predetermined value with respect to the alternating current. A receiver (21) is adapted to be connected across the power line to couple the line to the appliance. When the receiver detects transmitter generated pulses during phase windows occurring each alternating current cycle, power is applied from the line to the appliance for the remainder of such alternating current cycle. The transmitter has an adjustment (14) that permits the phase of the transmitter generated pulses to be modulated and the receiver has an adjustment (26) that permits the position of the phase windows relative to the alternating current to be changed. The transmitter generated pulses and the phase windows occur only on every other half cycle of the alternating current. The transmitter includes a controlled rectifier which is fired on every other half cycle of the alternating current to generate the transmitter pulses; after firing, the controlled rectifier remains in a conducting state during the remainder of the alternating current half cycle.

To minimize disturbance of the system voltage the period of alteration includes a voltage zero.

摘要： A power line data transmission system is disclosed in which data is transmitted over a line carrying alternating current power by varying or modulating the power factor of the line or the phase angle of the power on the line in accordance with a signal to be transmitted. A series connected reactance and switch are connected across the line. The switch is turned on and off in response to the data signal to be transmitted over the line. The phase angle of the voltage and current on the line is detected at the receiving location. The phase relation between the voltage and the current is detected or compared to produce a binary digital signal corresponding to the data sent over the line. The detection of the voltage and current being out of phase by a predetermined amount may be used to generate a signal indicating a digital one. The detection of the voltage and current being in phase may be used to generate a signal corresponding to a digital zero.

摘要： A network subscriber unit for an electrical energy supply network includes a control unit configured to control the power exchange of the network subscriber unit with the energy supply network, a device configured to determine a voltage zero crossing at a connection point of the network subscriber unit with the energy supply network and a receiving unit of the network subscriber unit configured to receive a signal of a reference time. The control unit is in this case configured to determine a time offset between a time of the voltage zero crossing determined by the device and the received reference time and to control the power exchange based on the time offset.
