Study of data fusion technique for measuring Yellow River sediment based on Internet of Things

To meet the requirement of sediment measurement in the Yellow River,data fusion techniques for multi-sensor,especially the technique based on multiple linear regression,are studied.The online measurement system of the Yellow River is architectured based on the Internet of Things(IOT).Considering the environment factors in this system,the water temperature,water depth and velocity sensors in the Internet of Things are integrated to measure the sediment concentration.Experiment results show that the multi-sensor data fusion technology can reduce the errors induced by environmental factors,improve the detection accuracy and enhance the stability by collecting the online multi-sensor information and data fusion on the Internet of Things.
