物联网系统异构数据的过滤及存储模型研究
Research on Filtering and Storage Model of Heterogeneous Data in Internet of Things System
摘要
Abstract
Aiming at the problem that the heterogeneous data flow in the Internet of Things system affects the efficiency of data processing, a heterogeneous data filtering and storage model of the Internet of Things system combined with RESTful WebService and MongoDB database is proposed. The concept of data points is proposed to abstract the physical quantity of the device node,and the data is filtered by setting the data point storage state,and the data are stored in the form of embedded document. The model has been tested to realize the selective storage of heterogeneous data in the Internet of Things system,and can effectively improve the storage efficiency and storage utilization of the database.关键词
