Problems solved by technology

[0003] 1. The meter reading system constructed by 485 wiring method requires too much construction, which is inconvenient for large-scale implementation;

[0004] 2. The narrow-band low-frequency power line carrier is greatly affected by the load characteristics of the power line, resulting in unstable and unreliable communication channels;

[0005] 3. High-speed carrier communication is a technology that uses low-voltage power lines to transmit carrier signals. It has a wide available bandwidth and can achieve high data rates. It uses existing power lines to form a broadband network to achieve broadband data and multimedia signal transmission. It can provide 1Mbit/ The data transmission rate is higher than s, but there are still reliability problems when using high-speed carrier communication alone. Communication cannot be realized when the carrier channel fails or a power outage occurs, and the cost of realizing high-speed carrier communication is relatively high, especially in the station topology. In the case of complex structures;

[0006] 4. The communication of the wireless communication method is simple and th
