Edge data acquisition system and method of wind turbine generator

The invention provides an edge data acquisition system of a wind turbine generator. Real-time monitoring, data acquisition and data analysis of at least one wind turbine generator can be realized through a plurality of edge data acquisition units and an edge management server. The system comprises a wind turbine generator, a plurality of edge data collectors and an edge management server. The edge data acquisition units are installed around to-be-acquired equipment of the wind generating set, and the edge data acquisition units communicate with one another by using power line carrier, LORA wireless and RS485 communication technologies to serve as ad hoc network nodes, so that an edge network is formed. And the edge management server obtains the data of the collected equipment through the edge network, is responsible for further analysis and decision making of the obtained data, and controls the corresponding wind turbine generator to perform corresponding operation based on an analysis result. Due to the fact
