| 摘 要： | 无线传感器通常用于环境监测,如气候变化、水质和监控灾害管理等。目前,灾害管理是一项十分关键和紧迫的工作,在海啸预警和预测系统方面尤为突出。本文在研制区域水文态势地理信息服务系统(RHSGISS)的基础上,为减缓灾害,研究出了海啸早期预警系统的一种本体式表达。该系统由地震监测台站、海底压力记录仪(BPR)和验潮仪等组成,其主要功用是解释复杂的多维数据。该数据由各种传感器、系统间的互操作性以及处理异构数据等生成。目前的核心问题在于将获取自海啸早期预警系统多个组件的异构数据进行融合以及提供基于Web网络的数据服务。面向特定陆表监测与应急响应任务,本文通过使用开放地理空间联盟(OGC)确定的传感器网络赋能实现(SWE)框架,构建了基于"北斗"卫星导航系统的GPNT服务体系,能为所有接入空天地一体化对地感测网环境下的用户共享互操作性和可伸缩性提供便利。本体因其功能上可以提供明确含义的信息,而成为了解决信息异质性问题的手段。本文在传感器网络数据与数据语义方面提出了一种面向服务的架构(SOA)模型,目的是要提供使用本体和Jena规范来表示更有意义的早期海啸预警系统信息。

| Abstract: | Wireless sensors are used for monitoring environments such as climate change, water quality and disaster management. Disaster management is a critical and emergent operation now, especially tsunami warning and prediction system. This work is based on the study of Regional Hydrology Situation Geographic Information Service System（ RHSGISS）, which runs a ontological representation of the tsunami early warning system. The early warning system comprises of systems like seismic stations, Bottom Pressure Recorder （BPR） and tide gauges. The critical task of the warning system is interpretation of the complex multidimensional data generated by various sensors and interoperability among the systems and handling of heterogeneous data. The critical issues now is in developing a methodology, to integrate heterogeneous data received from various components of tsunami early warning system and providing web based data service. Facing the specific task of surface monitoring and emergency response, we created a ＂BeiDou＂ - based GPNT service architecture by using the （）pen Geospatial Consortium （OGC） Sensor Web Enablement （SWE） framework, so that all of the users connecting to the Space - Air - Ground earth observation network could sharing the convenience of interpretability and flexibility. Ontologies are used as a means for solving the information heterogeneity problems because of their capability to provide explicit meaning to the information. In this paper we propose a Service Oriented Architecture （ SOA ） model for the interoperability of sensor networks data and semantics of the data. The purpose of the paper is to provide more meaningful information for Tsunami early warning system using ontology and Jena rule representation. |
