Problems solved by technology

[0006] Signal transmission on the 220V / 380V low-voltage power line has the isolation effect of the distribution transformer on the carrier signal, the interference of various interference signals on the power line to the carrier communication, the attenuation of the carrier signal by the load on the power line, and the difference between different carrier signals. Mutual interference, changes in power line impedance, and many other problems often lead to problems such as failure to transmit power consumption information, transmission errors, and insufficient transmission distance, making the entire system unable to work
