Description

technical field [0001] The invention relates to the field of power line carrier communication, in particular to a wireless bridge carrier communication device. Background technique [0002] Power Line Carrier (PLC) communication refers to a communication method that uses high-voltage power lines, medium-voltage power lines or low-voltage distribution lines as information transmission media for voice or data transmission. It is widely used in electricity meters, water meters, gas meters, etc. Remote meter reading system, smart home control, street light control and other fields. In the application of power line carrier communication, there are problems that different phases cannot communicate directly and high-frequency carrier signals are difficult to pass through transformers, transformers, and energy meters, which limits the scope of power line carrier communication. [0003] Therefore, there is an urgent need for a power line carrier communication device to solve the pro...
