Method and system for supporting isomeric sensor semantic registration

Abstract

The invention relates to the technical field of smart city geographic information service, and discloses a method and system for supporting isomeric sensor semantic registration. The method comprises the following steps that a first step is that a sensor meta-model body used for storing sensor metadata information is constructed; a second step is that a mapping relation from a sensor registration information model to the sensor meta-model body is established. The system comprises a device used for constructing the sensor meta-model body which is used for storing the sensor metadata information, and a device used for establishing the mapping relation from the sensor registration information model to the sensor meta-model body. The method for supporting the isomeric sensor semantic registration is beneficial to accurate discovery and efficient management of an isomeric sensor.

Description

technical field [0001] The invention relates to the technical field of smart city geographic information services, in particular to a method and system for supporting semantic registration of heterogeneous sensors. [0002] Background technique [0003] With the continuous development of earth observation technology and the continuous launch of a large number of remote sensing satellites, aerospace remote sensing has entered the development stage of multi-platform, multi-sensor and multi-observation means. There are a large number of heterogeneous sensors in the sensor network. For example, there are about 10,000 meteorological stations, 1,000 hydrological stations and 137 satellites in the Yangtze River Basin for hydrological monitoring, providing a variety of hydrological information. Heterogeneous sensors have different descriptions for the same concept and term, which will cause semantic conflict and redundancy. The demand for efficient management and accurate discover...

AI Technical Summary

Problems solved by technology

This registration and publishing method will cause information loss and greatly increase the query time

[0008] (2) When searching for sensor information, there are semantic conflicts and redundancy

If different description methods are used to describe the same attribute of the sensor, there will be semantic conflicts when searching for this attribute, making the query results incomplete

Existing services are difficult to solve the problem of semantic conflicts in the query process of heterogeneous sensors

[0009] (3) Unable to support semantic reasoning of heterogeneous sensors

These services can describe the syntactic level information of the registration information model, but cannot provide the reasoning information needed in sensor discovery and interoperability
