Research And Application Of Environmental Monitoring Based On Sensor Web

With the continued drive for environmental monitoring sensor networkapplications, as well as the further reduce of perception device software and hardwarecosts, all areas of the Earth’s resources and environment will be a lot of sensorresources to deploy and implement environmental monitoring sensor networkapplications. How to seamlessly integrate and share data from every corner of theearth has become the most important subject of Earth resources research in the field ofenvironmental monitoring.Due to the complexity of applications demand anddiversity of technical systems for environmental monitoring sensor network, it can beexpected in the short term there will be a large number of "heterogeneous","multi-source" space-time data streams, however, in the decision-making process, asingle data stream always perceived unable to meet the demand of precisedecisions.Take the geological disaster monitoring and early warning for example, itsdecision-making process is not only dependent on the displacement, strain and otherdata of the geological disaster monitoring sensor network, also need to providerainfall, wind speed, wind direction and hydrological monitoring Biography waternetwork provides a sense of the flow rate and other information.Therefore, to achievethe integration and sharing of multi-source heterogeneous spatial and temporal datastream is the essential requirement of geoscience sensor network applications.As earlyas2001, the Open Geospatial Consortium has accurately foresee the data on sensornetworks in the field of geosciences interoperability issues, and has established aspecial SWE (Sensor Web Enablement) Working Group, aiming at developing SensorWeb standards which can be found on the Web, access, analyze and integratedata-aware resource.Sensor web can provide infrastructures for heterogeneous dataintegration and sharing of sensor networks, so that the user can access the data via theInternet heterogeneous perception.This paper focuses on sensor networks for environmental monitoring data flowintegration and sharing of key technologies, the main contents are as follows:（1）Summarize the background of environmental monitoring, the development ofmonitoring technology, research status and significance.（2）In-depth analysis of OGC SWE specifications, based on the combination of the mountain environment monitoring applications actually designed for the needs ofNanchang Hangkong University of Ecological Environment Monitoring Sensor webarchitecture, including the perception of the network layer, data layer, applicationservice layer and application layer IV Environmental Monitoring layers.（3）Design the interface specification of Sensor Web sharing service, providingservices interface definition, description and discovery mechanisms, directorymanagement services, spatio-temporal data stream query services, streamingsubscription data and notification services.（4） Take the Wolong Mountain ecological environment monitoring sensornetwork flow integration and sharing of Nanchang Hangkong University as anexample, to verify the Sensor Web architecture and prototype system.（5）Combination of Sensor web environmental monitoring research Status, pointout the challenges facing Sensor web research, and Sensor web technologydevelopment trend of future prospects.
