归纳和总结了电能采集与计费系统的九个主要特点，通过对电能数据采集和处理各个环节的分析和研究，提出了该系统应实现的基本功能。根据该系统在数据采集和应用功能的实现这两个不同阶段的要求和特点，提出了将一个完整的电能采集与计费系统分成两个部分：电能数据采集与处理系统（前端系统）和电能数据应用系统（后台系统），并分别进行建设或实现的观点。 Summarize and summarize the nine main features of the system of energy harvesting and charging. Through the analysis and research of all aspects of power data acquisition and processing, the basic functions of the system should be put forward. According to the requirements and characteristics of the system in two different stages of data acquisition and application functions, this paper proposes to divide a complete electric energy collection and charging system into two parts: electric energy data acquisition and processing system (front-end system) and electric energy Data application system (background system), and were built or implemented point of view.
