基于物联网的城市轨道交通环境监测系统研究

An Environment Monitoring System of Urban Rail Transit Based on Internet of Things

在城市轨道交通系统中,环境信息监测系统是地铁安全、高效运营的基石。为适应城市轨道交通对环境监测信息化和集成化的要求,提出一种以物联网技术为核心的城市轨道交通环境监测系统。该系统在轨道区域内布设传感器节点,实现环境信息的感知和监测;通过汇聚树协议将监测信息以多跳通信方式传送到位于基站的根节点,由基站节点将收集到的数据上传到数据库服务器;最终由终端监控平台对数据进行统一处理。系统以监测区域完全覆盖为基础,同时引入节点节能策略,确保城轨交通的安全、高效运营。

Environment monitoring system is the foundation for the safe and efficient operation of urban rail transit.In order to meet the requirement that urban rail transit needs an information-based and integrated environment monitoring system,this paper describes a subway environment monitoring system based on Internet of Things.In this system,wireless sensor nodes are deployed in the area along track to monitor the environmental data and transmit the data to the root nodes deployed in base stations through Collection Tree Protocol（CTP） by the way of multi-hop communication,then root nodes upload the data collected from other nodes to a database server.The terminal monitoring platform linked to the database server processes the data at last.The system is based on the completeness of the monitoring area coverage incorporating the energy-saving strategy.The environment monitoring system for urban rail transit is safe and effective.
