Abstract

The invention provides a high-speed railway seismic data information acquiring and early warning system. The system comprises a seismic fluctuation information acquiring device, a current signal/numerical signal converting device, a device for dynamically generating a seismic hazard risk reference threshold, a determining device for starting an early warning program, a positioning device, a train control device used for controlling the speed of a train, a storage device and a control device, wherein a control module serves as a core of the whole system and is used for controlling the operation of the devices on the one hand, and is used for being connected with an external devices such as an external computer device to realize communication and control. According to the system, the reference threshold for evaluating the seismic hazard risk is generated by a dynamic generation manner; the history situation is continuously updated after the latest early warning with combination of the history hazard occurrence situation; compared with the history data, the risk pre-evaluation of one region can be completely and scientifically considered. The invention also provides a high-speed railway seismic data information acquiring and early warning method.

Description

technical field [0001] The invention relates to the technical field of high-speed railway environmental disaster early warning, in particular to a high-speed railway earthquake information collection and early warning method and system. Background technique [0002] Safety is the foundation of railway transportation, and high-speed railway trains run fast, so higher requirements are put forward for the safety guarantee system. Among the environmental disasters that affect the safe operation of high-speed railways, earthquakes are sudden disasters with a small probability of occurrence and great harm. Therefore, obtaining effective information on earthquake fluctuations and making a reasonable assessment of the degree of earthquake disaster can effectively reduce earthquake losses and provide guarantee for the safe operation of high-speed railway trains. [0003] At present, Japan, France and my country's Taiwan region have all established high-speed railway earthquake early...
