Internet of things data exchange method and Internet of things data exchange system

Abstract

The invention discloses an Internet of things data exchange method and an Internet of things data exchange system. The method comprises steps: a management side receives a directory retrieval request sent by a demand side, and a directory after being retrieved and filtered is sent to the demand side; if the directory after being retrieved contains needed data, the demand side sends a directory query request to the management side; the management side receives the directory query request, a data resource access mode involved in the directory query request is sent to the demand side; and the demand side sends a data exchange request to a provider according to the data resource access mode, and data resources returned by the provider are received, wherein the exchange data directory comprises data resource description information and the data resource access mode. Through providing an exchange data resource discovery mechanism based on the exchange data directory of the management side, problems of data discovery, data multi-source, heterogeneity and real-time performance existing in the data exchange process can be effectively solved.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to a data exchange method and system of the Internet of Things. Background technique [0002] The Internet of Things is the third wave of world informatization development after computers and the Internet. The Internet of Things is a kind of induction equipment such as radio frequency identification, infrared induction and video surveillance. On the basis of agreed agreements, objects are connected to the Internet for information exchange and communication, so as to realize intelligent identification, positioning, tracking, monitoring and management. network of. [0003] At present, in the fields of smart city, smart manufacturing, and public safety management, a large number of departments are involved in mutual cooperation, and there is an urgent need to integrate and process real-time IoT data from different systems. However, due to the wide range of data...
