Cross wind information collection and early warning method and system for high-speed railway

Abstract

The invention provides a high speed railway crosswind information collection and early warning system. The system comprises a crosswind information collection device, a current signal / numerical signal conversion device, a device for dynamically generating a reference threshold value of a crosswind disaster risk, an early warning program starting decision-making device, a positioning device, a train controlling device used for controlling the speed of a train, a storage device and a control device, wherein the control module serves as the core of the whole system, controls operation of all the devices, and also is used for being connected with external equipment such as an external computer device to achieve communication and control. The reference threshold value of the crosswind disaster risk is dynamically generated, and the historical conditions are continuously updated after the latest early warning happens in combination with the historical disaster occurrence conditions, so that compared with historical data, the risk pre-evaluation of a certain area is considered more completely and scientifically. The invention further provides a high speed railway crosswind 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 crosswind 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, crosswind is a kind of environmental disaster with high frequency and great harm. Therefore, effectively obtaining cross-wind information and making a reasonable assessment of the degree of cross-wind damage can provide a guarantee for the safe operation of high-speed railway trains. [0003] At present, countries such as Japan, Germany and France, which have developed high-speed railways earlier, have established disaster prevention systems according to their own ...

AI Technical Summary

Problems solved by technology

[0004] The construction of foreign high-speed railway disaster prevention systems adopts the mode of central control. Usually, high-speed railway lines have a large span. Out of consideration for data communication and project cost, most of the disaster prevention systems established outside are aimed at some specific locations or sections of the line. The environmental monitoring of the current high-speed railway exposed the shortcomings of the current high-speed railway disaster prevention system, which is unable to monitor the entire line and has low monitoring accuracy, although its structure is complex.
