Problems solved by technology

In recent years, the frequent occurrence of earthquake disasters in the world has had a great impact on the safety of railway operations, especially China is a country with frequent earthquake disasters. However, my country's railways have not yet established a safety early warning system based on earthquake disasters to prevent or mitigate earthquakes. Harm caused by disasters to railway transportation safety

Abstract

The invention discloses an earthquake monitoring and pre-warning device and a working method thereof, and relates to an earthquake monitoring and pre-warning technology. The earthquake monitoring and pre-warning device is mainly characterized by comprising seismic signal acquisition units, seismic signal monitoring units, a seismic signal processing unit and a client, wherein (two or more) seismic signal monitoring units are used for judging whether to send seismic alarm signals, each seismic signal monitoring unit is connected with two or more seismic signal acquisition units, the seismic signal monitoring units are connected with the same seismic signal processing unit, and the seismic signal processing unit is also connected with the client through a signal. The earthquake monitoring and pre-warning device has the characteristics of high pre-warning reliability and good timeliness, and is mainly used for the earthquake monitoring and pre-warning of a railway system.

Description

technical field [0001] The invention relates to earthquake monitoring technology, in particular to earthquake monitoring and early warning technology for railway systems. Background technique [0002] railway development [0003] With the development of our national railway, the railway has undergone several major speed increases. At 0:00 on April 1, 1997, the speed of China's railways was increased on a large scale for the first time, and the maximum speed of trains reached 140 kilometers per hour; the speed of passenger trains on national railways was increased to 54.9 kilometers per hour; The highest running speed of trains reached 160 kilometers per hour; the average travel speed of national railway passenger trains reached 55.2 kilometers per hour; the third large-scale speed increase at 0:00 on October 21, 2000, and the average speed of national railway passenger trains reached 60.3 kilometers per hour; October 2001 On April 21st, the speed was raised for the fourth ...
