Power Carrier Design Based on TCP/IP Reference Model of Computer Network Communication

The traditional power carrier based on digital theory can not meet the needs of long-distance and stable transmission of actual power signals. In this paper, we design a new power line carrier based on computer network communication TCP/IP reference model. According to the model, and based on the network interface layer, the overall hardware circuit including the network layer, transport layer and application layer is designed. The network layer solves the problem of carrier signal attenuation by exploring the parent node networking algorithm and routing strategy, and improves the effective communication distance of the carrier. The transport layer adopts the reliable transmission algorithm to get the missing data through the ACK response mode, and realizes the demodulation of the carrier signal by using OFDM technology, and improves the stability of the carrier communication. The application layer uses the data processing thread to call the network layer and the transmission layer algorithm to realize the effective processing of the carrier data. The experimental results show that the carrier machine designed in this paper achieves data transmission and collection. The network layer networking algorithm can efficiently set up the network, reduce the packet loss rate, and improve the communication stability and signal modulation ability.
