Wind driven generator and parameter collection system thereof

The invention discloses a wind driven generator and a parameter collection system thereof. The collection system comprises: at least one sensor, which is arranged in a wheel hub of the wind driven generator and is used for collecting environment operating parameters of the wheel hub; and a data processing module, comprising a parameter collection unit, a parameter reading unit and a storage unit, wherein the parameter collection unit is connected with all the sensors and is used for obtaining the environment operating parameters collected by all the sensors, the parameter reading unit is connected with a variable-pitch driver in the wind driven generator and is used for reading a load characteristic parameter of the a variable-pitch driver, and the storage unit is connected with the parameter collection unit and the parameter reading unit and is used for storing the environment operating parameters and the load characteristic parameter. According to the invention, the collection system arranged in the wind driven generator is employed to collect correlated data of the wheel hub's environment and the variable-pitch load characteristic in real time, thereby improving a simulated test environment of a variable-pitch system in a workshop.
