The bidirectional communication system of smart plug is the key to realize the intelligentization of plug. In order to address the communication problem of plug communication system, and to break the foreign tech-nology blockade, taking ELF electromagnetic wave as the communication carrier, the overall structure of the cross- pipe bidirectional communication system for smart plug has been designed. Based on the self-designed smart plug prototype, the communication code and the communication process of the entire communication system have been designed. An experimental platform has been built by simulating smart plug operation process. The experimental re-sults show that the designed bidirectional communication system of the smart plug can realize the communication of the smart plug, and the communication distance is 4. 8 m along the pipeline, which meet the actual operation re-quirements. The attenuation of the ELF electromagnetic signal is inversely proportional to the third power of the re-ceiving distance. The penetration capability of 20 Hz ELF electromagnetic signal is greater than that of the 30 Hz ELF electromagnetic signal. The conclusion can provide references for the design and optimization of the bidirec-tional communication system of the smart plug.
