Description

technical field [0001] The invention relates to a photovoltaic power station, in particular to a photovoltaic power station system in which monitoring data and production management data are transmitted through wireless communication. Background technique [0002] The photovoltaic power station system usually has a centralized control system and multiple photovoltaic array units; the optical fiber ring network is usually used to transmit data between the centralized control system and each photovoltaic array unit, for example, the monitoring data of the photovoltaic array unit is uploaded to the centralized control system, Production management data is bidirectionally circulated between the centralized control system and photovoltaic array units. [0003] The traditional optical fiber ring network needs to add communication cabinets, communication management machines, and optical fiber switches to each photovoltaic array unit. The fiber-optic cable deployment has the problem...

AI Technical Summary

Problems solved by technology

[0003] The traditional optical fiber ring network needs to add communication cabinets, communication management machines, and optical fiber switches to each photovoltaic array unit. The deployment of optical fiber cable has the problems of long cycle and poor flexibility; erecting optical fiber requires melting and embedding, and a large number of optical fibers are buried underground, which leads to maintenance. and maintenance difficulties, unable to quickly locate the problem

[0004] The reliability of the traditional optical fiber ring network depends on the ring network equipment and construction quality, and there are many fault points; and there are problems such as high cost of expansion, the need to lay new optical cables for expansion, long expansion period, and repeated joint debugging.
