Description

technical field [0001] The invention belongs to the technical field of remote real-time wireless monitoring, and in particular relates to a wireless communication system and method applied to remote real-time monitoring of wind power generating sets. Background technique [0002] Wind power generation is a comprehensive high-tech utilization of green wind energy. my country's land and sea wind resource technologies can be developed at 253 million kilowatts and 750 million kilowatts respectively. The construction of wind farms across the country has been accelerated, and it has now entered a period of large-scale development. At present, wind power generators ( Hereinafter referred to as the fan) except for the core of the control system, basically all of them have been localized. According to the design requirements of wind farms (hereinafter referred to as wind farms), generally speaking, the actual distance between the wind turbines is relatively far (more than 300 meters),...
