Measure the wind speed and direction through laser or ultrasonic radar, measure the inclination or offset of the tower at the center of the upper opening of the tower, and measure the tangential force and bending moment caused by gravity caused by the positive pressure of the computer cabin and impeller on the tower. At the same time, measure the torque caused by impeller deviation during power generation operation on the tower, and compare it with the wind turbine model design certification document, which is the load calculation report, To verify the differences between design parameters and operating parameters, and provide a solution for fatigue damage and life prediction of the tower drum.
The main spare part of the system is a multi-channel real-time bolt stress monitoring system, which is a wind turbine operating load testing system formed after secondary development. The iFAST-iot-24/8-channel real-time bolt axial force monitoring system consists of key components such as a 24/8-channel bolt pre tightening force measurement host, signal cables, probes, DC power supply, and software control system.
