高铁地震预警系统的研究

地震灾害对高铁的安全运营威胁颇大，为有效降低地震灾害对高铁安全运行的破坏，尝试研究一地震预警监控系统进行地震远程监控。本研究采用地震预警监控系统实时采集加速度传感器信号的同时进行滤波和P波捡拾等算法，实现地震识别和震级计算。经由实验证明，该地震预警监控系统能实现地震的实时监控和地震报警输出，可有效降低由地震灾害对高铁造成的危害1]2]。

Study on early warning system of high speed railway

Earthquake disaster has a great threat to the safe operation of high-speed railway. In order to effectively reduce the damage caused by the earthquake disaster to the safe operation of high-speed railway, an earthquake early warning monitoring system is studied to carry out remote monitoring of the earthquake. In this study, the seismic early warning monitoring system is used to acquire the acceleration sensor signal in real-time, and filter and P wave pickup algorithm are used to realize the seismic identification and magnitude calculation. The experiment shows that the earthquake early warning monitoring system can realize the real-time monitoring of earthquake and the output of earthquake alarm, which can effectively reduce the damage caused by the earthquake disaster to high-speed rail1]2].
