Integrated method of synaesthesia in internet of things for power distribution maintenance

Abstract

The power Internet of Things technology plays an important role in ensuring the normal operation of power grid. In order to improve the reliability of information perception communication of distribution network, this paper studies the key technologies of power line and wireless communication fusion, so that the two communication modes complement each other, improve the reliability of data transmission and communication coverage of distribution network, and adopt orthogonal frequency division multiplexing(Orthogonal Frequency Division Multiplexing, OFDM) to optimize resource allocation and enhance network performance. In this paper, a fusion method of low-voltage power line and micro-power wireless communication is proposed. By establishing a unified communication protocol in the medium access control layer of the hybrid communication network, realizing the optimal communication path networking in the network layer, and realizing the sub-service flow allocation based on the bit error rate demand factor in the business layer, the cross-layer fusion of low-voltage power line communication and micro-power wireless communication is realized in the service layer. The simulation results show that the performance of the hybrid communication network is better than that of other comparison networks. This paper presents an OFDM cross-layer resource allocation algorithm in multi-hop relay powerline communication networks and a power line and wireless communication fusion method including OFDM resource allocation.
