Abstract

The invention discloses a power line carrier and wireless dual-mode fusion communication method. The method adopts a communication protocol of a four-layer architecture during communication, and comprises the following steps: S1, after a communication service is generated, a physical layer performs diversity processing on input signals of a power line carrier communication channel and a wireless communication channel based on an OFDM modulation technology and outputs the input signals; S2, after receiving the data sending task, an MAC layer selects a power line carrier communication channel ora wireless communication channel to send data; S3, the network layer selects an optimal routing table path comprising a power line carrier communication channel and a wireless communication channel;and S4, an application layer collects data of the power line carrier communication channel and the wireless communication channel. The method of the power line carrier communication and wireless communication technology provided by the invention considers the advantages of the two technologies, realizes the heterogeneous converged network communication of the power line and the wireless, optimizesthe network performance, improves the collection success rate, and reduces the construction and use cost of a smart power grid.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication method combining power line carrier and wireless dual-mode. Background technique [0002] Power Line Carrier (PLC) and wireless are two main communication methods in the construction and application of smart grid. The power line is generally laid inside the wall, and the line is relatively safe and not easy to be damaged. However, due to line noise interference, time-varying input impedance, and signal attenuation, the communication quality of the power line carrier generally has certain fluctuations. Wireless communication includes various forms such as micro-power wireless, WIFI, wireless broadband, and mobile communication. It is convenient and does not require wiring. , climate and other factors. In the application process of the smart grid, the environment is complex, the business bearing requirements are diverse, and the transmission reliabil...
