摘　　要：为了使不同类型传感器网络能够自适应地访问和交换彼此的信息资源,研究分析基于传感网整合框架的传感观测服务。通过使用Tomcat服务器构建传感观测服务2.0系统,并针对传感观测服务SOS 2.0核心操作和信息模型,使用Java编程实现XML文档验证规则,首先通过使用schema对XML文档架构的正确性进行检验,其次使用schematron对XML文档架构的规范约束表达式进行验证。实验结果表明,借助XML文档验证规则,即可增加传感观测服务的语义信息,又能解决异构传感器之间的通信问题。In order to make different types of sensor networks adaptive to access and exchange in-formation,a Sensor Observation Service based on Sensor Web Enablement is studied in this pa-per.The Sensor Observation Service system version 2 .0 is constructed through Tomcat service. A XML document validation mechanism is designed by Java Language for the core operation and information model of the Sensor Observation Service.Firstly,the correctness of XML document through schema is validated.Secondly,constraints expressions of XML document through sche-matron are validated.Experimental results show that the semantic information of the sensor ob-servation service can be improved and the communication problem among heterogeneous sensors networks can be solved through XML document validation mechanism.
