Problems solved by technology

[0004] However, it has been found in practice that most of the existing carrier communication technologies transmit data within a short period of time by detecting the zero-crossing point of the AC waveform, the available communication time is short, the communication channels are few, and the communication channels are susceptible to interference, while Modern communication data frames are long, and the synchronization between the actual application and the AC waveform is not easy to control, resulting in too much waste of carrier communication channels, low bandwidth of carrier communication, and poor communication stability and reliability.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a two-way feedback coupling high-speed communication method and communication equipment. Background technique [0002] Power carrier is a unique communication method for power communication equipment. Power carrier communication refers to the technology that uses existing power lines to transmit analog or digital signals through carrier waves. The biggest feature is that there is no need to re-establish the network. data transfer. [0003] At present, in practical applications, there is inherent periodic pulse interference in the power carrier communication cable. The AC used is 50HZ and 60HZ, and its cycle is 20ms and 16.7ms. In each AC cycle, there are two peaks, two The secondary peak will bring two pulse interferences, that is, there is a fixed 100HZ or 120HZ pulse interference on the power line, and the interference time is about 2ms. Therefore, most of the existing...
