Embodiment Construction

[0015] Below in conjunction with accompanying drawing, the present invention will be further described;

[0016] A relay coupling technology for Homeplug, which is characterized in that: the three live wires of A phase 1, B phase 2, and C phase 3 on the left are all connected to the same coupling coil; the upper end on the right is the positive end of the sending circuit 4. The lower end is the negative end 5 of the sending circuit; the upper end is the positive end 6 of the receiving circuit, and the lower end is the negative end 7 of the receiving circuit.

[0017] Homeplug equipment A8 and Homeplug equipment B9 are respectively arranged at the two ends of the two power lines, and the Homeplug relay coupling gateway 12 is arranged in an appropriate position. The Homeplug relay coupling gateway 12 is provided with a Homeplug transceiver unit A13 and a Homeplug transceiver Unit B10, Homeplug transceiver unit A13, and Homeplug transceiver unit B10 are connected to each other, a...

Abstract

The invention relates to a relay coupling technology applied to Homeplug, which is implemented by jointing three live wires into a coupling coil, thus Homeplug signal transmitted from one live wire can be transmitted to a receiving end of a transmitting and receiving chip as well as the other two live wires through a coupling coil, and vice versa; placing a relay coupling gateway in a proper position to guarantee reliable communication among the relay coupling gateway, equipment A and equipment B; setting different network codes for equipment A and equipment B to ensure that the code of a transmitting and receiving unit A is identical with that of the equipment A and the code of a transmitting and receiving unit B is identical with that of the equipment B. The invention coupling connects the coupling transformer to any Homeplug equipment on the three live wires, thus being capable of directly communicating by power lines. Homeplug signal relay is carried out one time, so that equipment A and equipment B which can not directly communicate originally can communicate smoothly and reliably with the help of the relay gateway, thus satisfying the demand of high-tech information development.

Description

Technical field: [0001] The invention relates to the field of electronic technology, in particular to a relay coupling technology for Homeplug. Background technique: [0002] As the mainstream technology of broadband power line carrier, Homeplug is widely used in households and small and medium-sized enterprises. It provides another choice besides wireless for the environment where network cables are difficult. Compared with wireless (Wi-Fi), Homeplug has security and confidentiality. The distance is relatively far, no radiation, etc., but the Homeplug has weak mutual transmission performance between different AC live wire phases. In practical applications, because not every device that needs to access the Internet is on the same phase, this leads to The limitations of Homeplug in practical applications. On the other hand, when the load of the power line is large, the impedance of the power line is greatly reduced, and the transmission distance will be greatly shortened. Whe...
