分布式光伏充电站Web实时监控平台设计

摘要

随着光伏充电站基础设施的广泛建设,为电动汽车用户提供便利的同时,也为其管理带来了巨大的挑战;为了实现对光伏充电站更加有效的管理,在分析分布式光伏充电站数据通信方案的基础上,设计了一种光伏充电站Web实时监控平台;该平台基于ZigBee技术、GPRS-DTU技术、HTTP协议设计了直流充电桩无线传感器数据采集方案,部署数据库服务器、Web服务器以克服充电站无人值守的问题,实现对该分布式系统的集中管控,同时设计用于充电预约、监控、提醒等功能的安卓用户APP以提升用户体验,并对该系统进行实验验证;经验证,该设计方案能够有效实现对分布式光伏充电站的实时数据采集与Web端集中管控,为充电站无人值守与远程监控提供了一种有效的技术解决方案.%With the extensive construction of photovoltaic charging station infrastructure,not only provided convenience for the electric vehicles users,but also brought great challenges for its management.In order to achieve more effective management of photovoltaic charging stations,based on the analysis of the data communication scheme of distributed photovoltaic charging station,this paper designs a kind of Web real-time monitoring platform.Based on ZigBee technology,GPRS-DTU technology and HTTP protocol in this platform,we designed DC charging pile wireless sensor data acquisition scheme,while deployed the database server and the Web server in order to overcome the problem of charging pile unattended,to achieve centralized control of distributed systems,and we designed Android APP for charging reservation users to monitoring,alerts and other functions to improve user experience.And the experimental verification of the system is carried out.After verification,the design scheme can realize the real-time data acquisition and Web centralized control of distributed PV charging station.Provides an effective technical solution for the unattended and remote monitoring of the charging stations.
