In order to solve the problem of communication interrupt between the main control system and variable pitch system caused by loose contact of electrical slipping ring in wind turbines, the MCU and wireless communication technology is applied to the communication between the main control system and variable pitch system. In order to make the signal achieving wireless real-time transmission between the main control system and variable pitch system, the relationship between the MCU, the main control system and the variable pitch system have been established, and the application of MCU and the wireless communication module to form the communication device that can emit and receive the short distance wireless, real-time receive data from the master or variable pitch system and wireless transmit is proposed. e performance was evaluated based on the theory that wireless communication device can transmit data automatically. rough the analysis and validation, the results show that the system can realize the wireless transmission of data between the main control system and variable pitch system, and have great signi cance to the change of wind turbine internal communication mode.
