Application Framework for WSN-based High-speed Train Operating Environment Monitoring

The application of wireless sensor network(WSN) in the environment monitoring of highspeed train operation is still in its infancy. In this paper,the application of wireless sensor networks in monitoring environment of high-speed train operation is introduced and the application framework and application models of different scenarios are built in perspective of overall planning. Based on the research on the theory and application status of wireless sensor network(WSN)-based high speed train operating environment monitoring,this paper analyzes the demand of train operation environment monitoring,and establishes the overall framework and network models of the Wayside WSN,the Onboard WSN,the Onboard-Wayside WSN and the Station WSN. This paper also puts forward some key problems involved in the research of WSN-based high-speed rail operations environment monitoring system,which plays a guiding role in further research of the WSN-based high-speed rail operation environment monitoring system.
