Internet of Things equipment data acquisition method, medium and system based on public cloud

Abstract

The invention provides an Internet of Things equipment data acquisition method, medium and system based on public clouds, and belongs to the technical field of Internet of Things clouds, the Internet of Things equipment data acquisition method, medium and system based on public clouds comprises the following steps: acquiring Internet of Things equipment identification parameters, Internet of Things equipment acquisition parameters and data caching parameters; receiving original collection data collected by the Internet of Things equipment and dividing the original collection data into a plurality of collection data fragments; performing data preprocessing on the plurality of collection data fragments to generate preprocessed collection data; calculating a device contribution degree value based on the data contribution equation set; dividing high and low priority collection data according to the contribution degree value of the equipment; constructing a hierarchical data cache structure to store high-priority acquisition data and low-priority acquisition data; adjusting an equipment sampling frequency value, a data priority level and a cache capacity value according to the quality evaluation numerical value and the feature evaluation numerical value; according to the invention, the data processing efficiency of the public cloud can be improved, and the difference management and intelligence level is improved.
