In the wind power station monitoring system solution, AOPRE-LINK8416 is used to place an industrial Ethernet switch at the bottom of the tower of each wind turbine. The ring network equipment and core equipment are interconnected through 1000m optical fiber. Two AOPRE-LINK8280 are installed in the core room to gather multiple ring network data flows respectively. Each fan is composed of AOPRE-LINK8280 Industrial Ethernet switch and multiple Gigabit ring network redundancy protocols to ensure worry free switching of the network and improve the efficiency of network data transmission.
