Fast Sensor Process Modeling and Registration in Sensor Web

摘要

Sensor modeling and registration is the basis of sensor centralized management and sensor information sharing in Sensor Web. According to the SensorML standard developed by OGC, this paper proposes a user-oriented fast sensor process modeling and sensor registration method based on the in-depth analysis of the SensorML conceptual model of sensor description. With this method, all the information required to describe the sensor will be divided into three categories with defining the necessary elements, optional elements and element format for each category: Identification, Capabilities and Contact. Then the same category of information will be presented in the same form. Users only need to fill in these forms according to the process, and then complete the sensor modeling process by submitting these forms to the server. Finally, the server receives the information to generate XML formatted sensor information models of the SensorML standard. Users could complete the sensor registration with these models. In order to verify the feasibility of this method, this paper designs and realizes a fast sensor modeling and sensor registration online system based on the SensorML standard of version 1.0.1, and registers an in situ sensor to Sensor Observation Service(SOS) successfully by this system.
