随着全球能源互联网的发展及国内智能电网的深入建设，国内用电信息采集系统已逐步实现全自动化。现有用电信息采集系统通信方案主要采用远程通信方式加本地通信方式组成。文章探讨了用电信息采集系统的本地通信各技术的应用效果，并探索性地提出基于低压电力线宽带载波技术及用电信息采集系统完成水、气、热、电表四表采集，完成了从表记到后台主站的设计方案，该方案充分利用了低压电力线宽带载波的技术优势、用电信息采集系统的功能优势，可提升数据采集效率，降低建设成本，为节能减排提供有力支撑。%With the development of global energy interconnection and construction of smart grid in China,the electricity consumption information collection system has realized the complete automation gradually. The communication scheme of the existing electricity consumption information collection system adopts a combination mode of remote communication and local communication. This paper discusses the application effect of local communication technology,and proposes a scheme to achieve the information collection of water,gas,heat,and electricity together based on broadband power line carrier technology and electricity information acquisition system. The design scheme is achieved from the table to the background master station. The proposed scheme is able to make full use of the technical advantage of low-voltage power line broadband carrier and electricity information collection system,improving the efficiency of data collection,reducing construction cost,providing strong support for the national energy-saving emission reduction.
