High-efficiency data acquisition system based on Internet of everything

The invention relates to the technical field of data processing, in particular to an efficient data acquisition system based on Internet of everything. Obtaining an association range according to the interval characteristics of the extreme points in the monitoring data sequence, and obtaining association data segments of the data points according to the association range and the abnormal degrees of the data points; and obtaining smoothing parameters of the data points according to the fluctuation characteristics of the associated data segments. And obtaining the smooth parameter credibility of the data points according to the distribution characteristics of the extreme points in the associated data segments. And obtaining an adaptive smoothing coefficient according to the smoothing parameter, the smoothing parameter credibility and a preset smoothing coefficient. According to the method, the corrected smoothing coefficient is obtained according to the abnormal degree of the data points, the smoothing paramete
