Research and Application of Power Terminal Communication Access System Based on Heterogeneous Network Technology

Abstract In recent years, the basic business of power distribution production, such as distribution automation, power consumption information collection and load control, distributed power supply and so on, is growing rapidly, and the demand for power terminal communication access is increasing. Based on the analysis and research of terminal communication access technology, this paper proposes a heterogeneous network combination scheme which integrates multiple terminal communication technologies to solve the problems such as the limitation of existing terminal communication access network technology on the power distribution side. Heterogeneous network networking technology realizes the integration application of wireless private network, low-power wide area network, medium voltage broadband carrier and other channels. It can give full play to the advantages of various communication modes, improve the communication guarantee ability, meet the requirements of full coverage of power terminal communication access network business, provide strong channel support for terminal information return, and provide communication system construction for distribution terminal Useful reference.
