A multi-channel meter smart communication method based on low-voltage power line broadband carrier

Abstract The conventional meter intelligent communication method establishes a communication network with an existing network, which is affected by background noise, impulse noise, and so on, and the communication quality is degraded. Therefore, a multi-channel meter intelligent communication method based on a low-voltage power line broadband carrier is designed. The characteristics of low-voltage power line broadband carriers for meter communication are extracted, and the background noise and impulse noise of power line carrier communication are analyzed to determine the impedance characteristics of the meter communication channel. Based on the low-voltage power line broadband carrier, the meter intelligent communication network is generated, and the fast path of meter communication is evaluated to meet the demand of multi-channel communication of the meter. Comparison experiments are used to verify that the method has a better quality of intelligent communication and can be applied in real life.
