RS-485总线架构的双无线通信光伏电站监控系统

Dual-wireless communication of monitor system for photovoltaic plant based on RS-485 bus architecture

为了更好地将区域分散的光伏电站系统集中管理和调度,提出了一种RS-485总线架构的ZigBee和3 G双无线通信的光伏电站远程数据监控系统。系统通过ZigBee无线网络将光伏电站内部短距离关键设备的数据采集并上传至主控制器,主控制器将数据保存的同时启动3 G模块将数据发送到远距离数据库服务器,远端服务器进一步接入以太网与采用浏览器/服务器(B/S)软件设计模式的上位机无缝连接,具有较好的应用性和扩展性。

In order to centrally manage and schedule distributed photovoltaic plant better,based on RS-485 bus architecture,a remote data monitor system combined with ZigBee and 3G dual-wireless technology is proposed for photovoltaic plants. The system firstly acquire data of internal short distance key facilities in photovoltaic is designed by ZigBee wireless networks,and the collected data is uploaded to the master controller. Then,master controller save the data and at the same time activate the module of 3G to launch the data to remote database server. Finally,remote server connects to Internet and communicates with host computer which uses Browser/Server（ B/S） software design mode without any barriers. This designed system has good applicability and scalability.
