Embodiment Construction

[0021] figure 1 It is a flow chart of Embodiment 1 of the method for storing Internet of Things node information of the present invention, such as figure 1 As shown, the method includes:

[0022] Step 101, receiving a storage instruction sent by an application system in the Internet of Things, the storage instruction carrying node information to be stored;

[0023] The application system involved in this embodiment may be a plurality of different Internet of Things application systems, such as a road video monitoring system, a road flow detection system, and the like. In existing practical applications, due to the different storage formats of node information in different application systems, when it is necessary to comprehensively use the data information collected by nodes in different application systems, it is necessary to use the storage format adopted by each application system The node information in each application system is analyzed to obtain the required data info...

Abstract

The invention provides a method and a device for storing node information in the Internet of things. The method comprises the steps as follows: receiving a storage instruction sent by an application system in the Internet of things, wherein the storage instruction carries to-be-stored node information, extracting key information from the to-be-stored node information, determining whether a metadata model taking the key information as an index exists or not, and storing the to-be-stored node information via the storage form described by the metadata model if the metadata model exists. The technical scheme provided by the invention realizes unified storage of node information in all application systems in the Internet of things through the metadata model, and further facilitates the improvement on the efficiency of querying node information in each application system.

Description

technical field [0001] The invention relates to an information storage technology, in particular to a method and device for storing node information in the Internet of Things. Background technique [0002] As an extension of Internet applications, the Internet of Things aims to realize universal communication between any person or object. At present, the application of the Internet of Things is mostly launched for specific applications, and a dedicated Internet of Things application system is built. In order to realize the integrated use of relevant data information in each application system, it is necessary to be able to query the node information in each application system. [0003] At present, since each application system generally independently identifies and stores node information, if you want to query the node information in each application system, you need to master the identification methods of node information in each application system, and then query and anal...
