Data fusion method and device based on Internet of things, and computer readable medium

The invention discloses a data fusion method and device based on Internet of things, and a computer readable medium. The method comprises the following steps of collecting detection data detected by asensor in the Internet of things to obtain an original detection data set; performing consistency detection on the original detection data set; removing abnormal data from the original detection dataset to obtain a target detection data set; according to the target detection data set and the corresponding historical detection data, calculating the comprehensive weight value of each target detection data sample in the target detection data set; according to each target detection data sample and the comprehensive weight value, calculating the fusion result of the target detection data set. The method has the advantages that the target detection data set is subjected to data fusion by combining with the historical detection data; the influence of the historical detection data on the data fusion result is sufficientl
