It is particularly important to monitor the bolt connection preload for wind power generation.Researchers design an embedded intelligent monitoring system which bolts pre-tightening force,sampling,data transmission by the pre-tightening force of three parts,and the bolt theme is regarded as the sensor to collect pre-tightening force data based on a short distance wireless communication technologies.Data is transmitted to set control center monitoring system through optical fiber in monitoring of prestressing force of bolt connection.It provides a judgment means to judge the reliability of bolted structure and has a wide application space.
