Embodiment Construction

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0032] IoT data corresponds to sensing devices in the real world. In digital construction, the requirement of IoT data fusion based on the real-world geospatial information domain is often proposed. Therefore, the application of IoT data needs to be closely integrated with geographic information data. The Beidou grid code is a discretized, multi-scale regional location identification system developed on the basis of the GeoSOT geospatial subdivision theory. An arbitrary grid with an accuracy of 1.5 cm endows the world with a unique one-dimensional integer code. The Beidou grid code can automatically establish the spatial association between physical objec...

Abstract

The invention discloses an Internet of Things multi-dimensional data fusion system and method. The method comprises the steps that a data supply direction data fusion sharing center provides Internetof Things data or publishes a data service, a data demand direction data fusion sharing center submits a data demand, and the data fusion sharing center integrates an Internet of Things spatio-temporal data description model and a data fusion model; the Internet of Things spatio-temporal data description model takes a Beidou grid code as a spatial domain identifier, and performs mapping processingon Internet of Things data of different data standards to complete data resource normalization; and the data fusion model uniformly describes detailed features of data required by a data demander, extracts feature vectors based on a geographic space information domain according to the space-time data demand description of the Internet of Things, and performs data fusion according to the data features by taking Beidou grid codes as space domain identifiers and adopting a data fusion algorithm. According to the invention, the fusion efficiency of the Internet of Things spatio-temporal data in the geographic space information domain is improved.

Description

technical field [0001] The invention relates to the technical field of Internet of Things data, in particular to a multi-dimensional data fusion system and method of the Internet of Things. Background technique [0002] At present, under the promotion of the national informatization development strategy in the new era, digital construction in various fields such as smart cities, smart transportation, and smart manufacturing is steadily advancing. Digital construction involves multi-departmental collaboration and coordination of various systems, which puts forward higher requirements for the fusion and processing of spatio-temporal data of the Internet of Things. However, due to the realistic constraints of Internet of Things applications such as massive sensing nodes, isomerization of sensing data, and islanding of system construction, there is a bottleneck in the fusion of multi-source heterogeneous Internet of Things data based on the fusion of geospatial information domai...
