摘要
设计了一种分布式光伏电站数据通讯管理机,包括硬件系统和软件系统.硬件系统基于ARM嵌入式处理器设计,通过RS485/232串口对光伏电站终端设备的实时数据进行采集并解析处理,采用以太网/GPRS与光伏电站控制系统的服务器相连,实现数据的远程无线通讯和传输.软件系统基于多任务实时系统Linux,采用模块化设计,包含了任务管理、内存管理、时间管理和同步通信等功能模块.该通讯管理机具有对分布式光伏电站监控数据的实时采集、存储、分析处理、上传和转发等功能.
A distributed photovoltaic plants data management unit was designed. The hardware was developed on embedded ARM micro-processers, which collected and analyzed the real-time data of the distributed photovoltaic generation plants through RS485/232 serial ports and remote wireless communicates with the server of the PV plants monitoring system through Ethernet/GPRS. The software of the unit was designed on the real-time multi-task system Linux, including the function modules of task management, storage management, time management and remote wireless communication. The functions of the unit include acquisition, processing, upload and retransmission of the data of distributed photovoltaic power generation plants.
