基于北斗技术的铁路边坡安全监测系统及应用

Railway Slope Safety Monitoring System and Its Application Based on BeiDou Technology

以北京西工务段管内某山区既有客货共线铁路土质路基边坡为例,在日常工务铁路线路维护中引入北斗定位技术,进行基于北斗技术的铁路边坡安全监测系统的应用。系统由运行北斗卫星与地面监测设备等组成,通过与云平台连接,实现监测数据的自动化监测、传输。通过项目应用表明,优化监测设备选址、根据区域地形合理设置与基准站距离等是提高北斗监测水平的有效手段;与此同时,根据变形对铁路安全影响程度差异,合理设置北斗变形监测预警阈值,使北斗技术更广泛地应用于铁路监测方面,更好地为铁路智能建造和运营安全服务。

This article takes the soil subgrade slope of an existing passenger and freight railway in a mountainous area in the Beijing West Engineering Section as an example, the BeiDou positioning technology is introduced in the daily maintenance of the railway line, and the application of the railway slope safety monitoring system based on the BeiDou technology is carried out. The system consists of running BeiDou satellites and ground monitoring equipment, etc., and realizes the automatic monitoring and transmission of monitoring data through connection with the cloud platform. The application of the project shows that optimizing the location of the monitoring equipment and setting the distance from the reference station according to the regional topography are effective means to improve the monitoring level of the BeiDou;at the same time, according to the difference in the degree of influence of the deformation on the railway safety, reasonable setting of the BeiDou deformation monitoring and early warning thresholds, making BeiDou technology more widely used in railway monitoring, and better serves for the safety of railway intelligent construction and operation.
