Research on Online Monitoring and Analyze of Hydraulic Turbine Based on Low Cost, Fast and Internet of Things Technology

Abstract In view of the problems such as difficulty in and high cost vibration signal collection rotating mechanical shaft, this paper proposes a low-cost, fast, stable reliable hydraulic turbine wheel online monitoring scheme specially designed to imbalance dynamic balance counterweight shaft. Three high-frequency wireless acceleration sensors are installed on shaft monitor signals three directions real time. Vibration sent cloud platform facilitate data storage. The is decomposed by WOA-VMD. time domain shows running track guide rotor. frequency used analyze machine predict health status according change. According system, completed experiment experiment, proved feasibility rationality has good application prospect practical value.
