基于ZigBee的铁路隧道防护门监控系统研究

Research on Railway Tunnel Protective Door Monitoring System Based on ZigBee

针对传统隧道防护门监控系统成本高、占空间、安装维护困难以及监控信息不全等问题,提出基于ZigBee无线通信技术的铁路隧道防护门监控系统。各隧道防护门监控单元与集中监控器间通过ZigBee进行灵活组网,实现了防护门开闭监控及变形、脱落等状态的预警;系统具有远程集中监控防护门运行状态、故障报警定位,危险预警等功能;在保证安全可靠的同时,节省了光电缆敷设的工作量,降低了成本,安装维护方便,有助于进一步保障铁路行车安全。

To address the problems of high cost,large space occupation,difficult installation and maintenance and incomplete monitoring information of traditional tunnel protective door monitoring systems,a railway tunnel protective door monitoring system based on ZigBee wireless communication technology is presented.The tunnel door monitoring units and the centralized monitors are flexibly networked through ZigBee to realize the monitoring of the opening and closing of the protective door and the early warning of deformation and falling off.The system has the functions of remote centralized monitoring of the operating status of the protective doors,fault alarm and location,early warning of dangers.While ensuring the safety and reliability,the system saves the workload of optical cable and electric cable laying,reduces the cost,and is convenient for installation and maintenance,which is helpful to further ensure the safety of railway train operation.
