Research On Information Modeling Of Sensor WEB Based On SWE

There are differences in the heterogeneous sensor network from observation data, various types of sensors, and intermediate exchange information formats. In order to effectively shield these differences and achieve interoperability of these heterogeneous sensor networks, it has theoretical significance and practical application value to research the sensor WEB information modeling and the methods of information modeling.Firstly, this paper analyses the present sensor WEB information development situation at home and abroad and expounds function of seven SWE standard components. SensorML concept, characteristic, conceptual model of simple data types have been researched in detail and basic structure of sensors observation and measurement have been studied based on SensorML and the framework of sensor WEB information model have been abstracted based on SensorML sensor.Secondly, this paper researches on the sensor information modeling method based on XML and introduces the XML scheme and key technology of modeling based on XML. The research applies to the technology of the combination with XML and UML, analyzes in detail the abstract model of SensorML, makes the XML document format information description, and summarizes the abstract method and principles of the sensor and sensor observation information.Then, this paper combines actual need to design infrared building sensor information system of the overall framework, designs the infrared building sensor node information model, observation and measurement information model, describes the general system framework of information.Finally, this paper realizes the client of the infrared building sensor information system according to the design of the infrared building sensor information model, through the design of the client and database of the infrared building sensor information realizes the configuration of the user information, sensor information and the submitting of observation information, which verified the adequacy and meaning of information modeling.
