In order to solve the problems of multiple relays,large long-distance transmission attenuation and poor reliability in high power line communication(HPLC)communication of the smart meter,this paper proposes a method of meter communication based on balanced hybrid routing.Firstly,the smart meter communication module is transformed into HPLC and micro power wireless dual-mode communication mode to improve the stability of data transmission.On this basis,through the analysis of the communication connection relationship of the meter,the neighbor relationship table between the collector and the smart meter is established,and the topological relationship is formed.Secondly,the re-transmission routing table is saved for each smart meter in the distribution station area through a reliable transmission path.Thirdly,based on the balanced hybrid routing algorithm,dynamic routing switching and optimal path selection between smart meter HPLC and micro power wireless communication are realized.Finally,the paper uses simulation process to verify the feasibility and effectiveness of the proposed method.
