In view of the complex structure of distributed photovoltaic power station, the traditional distributed photovoltaic power station monitoring system can not achieve the effectiveness and accuracy of distributed photovoltaic power station monitoring. In order to solve this problem, the application research of ZigBee in distributed photovoltaic power station monitoring system is proposed. Based on the overall architecture of distributed photovoltaic power station monitoring system, through the design of distributed photovoltaic power station monitoring module and distributed photovoltaic power station monitoring system induction module, the system hardware design is completed. Through the processing of distributed photovoltaic power station monitoring data and the design of distributed photovoltaic power station monitoring process, the system software design is completed, and the ZigBee technology in distributed photovoltaic power station is realized. The test results show that the distributed photovoltaic power station monitoring system based on ZigBee technology can not only improve the effectiveness of distributed photovoltaic power station monitoring system, but also improve the accuracy of distributed photovoltaic power station monitoring system.
