面向生态环境监测的传感器观测服务研究与应用

摘要

传感器观测服务规范(Sensor Observation Service，SOS)对于实现异构传感器网络之间的数据共享与互操作性具有重要作用。本文主要介绍了SOS规范产生的背景以及该规范的主要内容，并将该规范应用到黑河流域生态环境观测无线传感器网络中，设计并实现了规范中的核心功能及相应的服务端与客户端，从而验证了该规范的可行性，为Sensor Web在生态环境观测领域的应用提供了参考。%The SOS(Sensor Observation Service) specification plays a vital role for implementation of the data sharing and interoperability among the heterogeneous sensor networks. This paper introduces the background and the main content of the SOS standard, and presents how we apply the specification to design and implement the core functions of the standard and the corresponding server and client applications for the Heihe basin ecological environment observation wireless sensor networks. The results veriifed the feasibility of the speciifcation and offer a reference for the further study on the Sensor Web oriented ecological environment monitoring.
