摘要
基于对处于偏远地区的光伏发电基站电源运行情况进行远程控制和检测的目的,本系统设计了具有针对性的监测系统,基站电源发电的电压、电流值每5 s钟采集一次,通过GPRS模块无线高速传输到总站计算机进行检测和控制。进行串口通信实时数据采集、存储、查询,并完成对上位机串行口接收数据设置、上位机对下位机工作情况的检测和系统功能的设定。探讨了GPRS模块进行数据传输的过程,MC35i驱动及AT指令的编写和数据传输协议的制定。在大量的实验的基础上,采集到日光强度改变时基站电源运行情况的数据,为提高太阳能电池的利用率提供了实践依据。
In order to control and test the operation of remote power station ,this paper design pertinency monitoring system. The power is used. The current and voltage of power is colected every five seconds once. The data is transmissed through GPRS module which is a wireless high-speed transmission. The function of the System is to collect data, storage and inquire. This paper also introduces receiving data setting of PC serial port, work testing about PC to power control machine and system function setting. In a large number of experimental,we collect abundant operation data when sunlight continuely changes. The data provide practical base to improve the utilization rate of solar cells.
