| 摘 要： | 为了满足列车及城轨安全运行的需求,根据地上(地下)的铁轨延伸地形特点,设计开发了一套列车行车状态无线监测系统;详细阐述了以CC2430为核心的传感器节点、以CC2430和MCP2515为核心的网关节点的软硬件设计和工作流程;实测结果表明,当安装在铁轨旁的相邻无线传感节点的距离不超过60m时,传输成功率可达96％以上,能够实时、可靠地监测铁轨压力、车辆轴承温度和声音参数的变化情形;系统完全不影响车辆的正常运行,是对现有铁路列车运行状态监控系统的有益补充.

| Abstract: | In order to meet the requirement of train running status monitoring in railway environment and according to the landform characteristics of them in the rail laneway,this paper introduced a reliable railway running status monitoring system based on wireless sensor networks(WSN).The sensor node of the system was mainly designed by CC2430;with MCP2515 the sink node was designed.The design of hardware and the flow chart of software were given.Through experiments in a railway station,it checks the transmission characteristic at 2.4 GHz,and also makes sure that while the distance between two wireless sensor nodes is 60 meters,the system can monitor the status of the lane way and the train under well real time and reliable,in addition it also have no influence on the normal railway working.The system makes a good supplement to the existing railway monitoring system. |
