摘　　要：配用电通信网,作为直接服务于客户的电力系统中低压网络,是智能电网的关键环节,配用电通信网的规划是当前电力通信网络组建的重点和难点。低功耗广域网技术作为物联网领域的新兴热点技术,在功耗、传输距离和网络成本方面弥补现有通信技术的短板,是配用电通信网未来发展的重要支撑技术手段。基于对上述问题的分析,本文提出了基于低功耗广域网技术的智能配用电网络架构,包含信息采集域、信息传输域和应用服务域,完成了信息采集子系统、信息传输子系统和应用服务子系统的软件流程设计,并在信息采集子系统中细化了信息采集模块与微控制器模块的软件流程。为完善和丰富新技术的应用场景贡献了一定的研究价值。Equipped with electric communication network, is a direct service in the user’s low-voltage power network, is the key to the smart grid, with the construction of electric communication network is the current power communication network construction of the key and difficult. Low-power WAN technology, as a hot new technology in the field of IoT, makes up for the shortcomings of existing communication technologies in terms of power consumption, transmission distance and network cost, bringing new opportunities for the development of EEE networks. Based on the analysis of the above problems, this paper proposes an intelligent power distribution network architecture based on low-power WAN technology, including information collection domain, information transmission domain and application service domain, and completes the information collection subsystem, information transmission subsystem and application Service subsystem software flow design, and information collection subsystem in the thinning of the information acquisition module and the microcontroller module software flow. The new technology for industrial applications has laid a certain foundation for the study.
