Sensor Web的SOS服务研究与实现

Sensor Web是NASA/Jet Propulsion Laboratory(JPL)的Kevin Delin首先提出并将其定义为被部署用来监控和探测新环境,内部能够相互通信的分布式传感器组成的网络系统。自OGC提出Sensor Web的相关标准以来,传感器监测服务SOS就是最基本最核心的服务规范。文章首先对SWE的传感器观测服务SOS核心操作进行介绍,然后设计了传感器观测服务SOS架构,并对每层作了说明,利用Java、Tomcat等技术对SOS的架构进行部署和测试。利用所部署的SOS架构中的核心操作可获取实时或历史的观测数据。

Research and implementation for sensor observation service architecture of Sensor Web

The term ＂Sensor Web＂ was first used by Kevin Delin of NASA, to describe a novel wireless sensor network architecture where the individual pieces could act and coordinate as a whole. In this sense, the term describes a specific type of sensor network： an amorphous network of spatially distributed sensor platforms （pods） that wirelessly communicate with each other. Since the standards of Sensor Web is proposed by the open geospatial consortium, the observation service has become the most basic core service specification. The core operation of sensor observation service based on SWE is introduced in detail. The architecture of sensor observation service is designed, including emphasized and data interaction all of each level of the architecture. Finally, technology of java and tomcat to deploy and test the architecture, SOS architecture can be used to deploy the core operations or get real-time or historical observations.
