Real-Time Monitoring and Pre-alarm System for Dangerous Mountains in the Railway Line

There appear frequently natural phenomena such as collapse, landslide along the railway line, which badly threaten the transport safety of the railway. This system adopts the method of auto-monitoring, and the monitoring content is the earth´s surface deformation. At the front, through high-accuracy displacement sensor, the deformation signals of the dangerous mountains can be acquired, then data collection is carried out at the regular intervals, using the GPRS wireless communication technology, and the real-time monitoring and pre-alarm for dangerous mountains can be achieved. This method is simple, convenient and penetrating, with lower-cost and higher -accuracy.
