基于ZigBee传感器网络的渝高速铁路外部环境安全监测系统研究

Research on the External Environment Safety Monitoring System of Handan High-speed Railway Based on ZigBee Sensor Network

在高铁经济快速发展的过程中,运行安全是极为重要的前提,没有良好的安全保障,高铁建设将无从谈起。本文根据重庆地区的复杂地形及气候特征,从线路基础设施、自然环境与灾害等可能引起高速铁路安全隐患的外部因素入手,结合嵌入式技术和4G通信技术,对基于Zig Bee无线传感器网络的重庆高铁外部环境安全监测系统的建设进行了研究与探索,以弥补现有环境监测系统灵活性差、布线复杂、监测范围受限、建设成本高等缺陷,对于降低重庆高铁运行风险指数、提高安全运行能力有着重要的现实意义。

In the rapid development of the high-speed rail economy,operational safety is an extremely important prerequisite.Without good safety and security,the construction of high-speed rail will be impossible.Based on the complex terrain and climatic characteristics of Chongqing area,this article starts with the external factors that may cause safety hazards in high-speed railways such as line infrastructure,natural environments and disasters,and combines embedded technology and 4G communication technologies with Chongqing High Speed Rail based on ZigBee wireless sensor networks.The research and exploration of the external environmental safety monitoring system has been carried out to compensate for the defects of poor flexibility,complicated wiring,limited monitoring range,and high construction cost of existing environmental monitoring systems.It is important for reducing the risk index of high-speed railways in Chongqing and improving the safe operation capability.The practical significance.
