Abstract

The present invention provides a high-speed railway seismic data information collection and early warning system, including a seismic fluctuation information collection device, a current signal / numerical signal conversion device, a device for dynamically generating a reference threshold for earthquake disaster risk, a decision device for starting an early warning program, The positioning device, the vehicle control device for controlling the speed of the train, the storage device, and the control device. The control module is the core of the entire system. On the one hand, it controls the operation of the aforementioned devices. Connections enable communication and control. In the present invention, the reference threshold for earthquake disaster risk assessment is dynamically generated, combined with historical disaster occurrences, and the historical situation is continuously updated after the latest early warning occurs, so that it can be compared with historical data to achieve a more complete and scientific Consider a pre-assessment of risk in an area. The invention also provides a high-speed railway seismic data information collection 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...
