Rainfall information collecting and early-warning method and system for high speed railway

Abstract

The invention provides a rainfall information collecting and early-warning system for a high speed railway. The rainfall information collecting and early-warning system comprises a rainfall information collecting device, a current signal / numerical signal conversion device, a device for dynamically generating rainfall disaster risk reference threshold values, an early-warning program starting deciding deice, a locating device, a train control device for controlling the speed of a train, a storage device and a control device; a control module serves as the kernel of the whole system, on one hand, the control module controls operation of all the mentioned devices, and on the other hand, the control module is used for being connected with an external computer device and other external equipment to achieve communication and control. According to the system, the reference threshold values for evaluating rainfall disaster risks are dynamically generated, and combined with historical disaster occur conditions which are continuously updated after the newest early-warning occurs, risk beforehand evaluation of a certain region is considered more completely and scientifically through comparison with historical data. The invention further provides a rainfall information collecting and early-warning method for the high speed railway.

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 rainfall information collection and early warning method and system. Background technique [0002] During the high-speed operation of the train, it is necessary to judge whether there is a heavy rain in front of the line or there is an environmental disaster such as accumulated rain on the road section, so as to reduce the speed of the train or take other measures to ensure the safety of the train. In addition, the railway management department also hopes to be able to monitor the current situation of rainfall on the line at all times, obtain real-time safety information on the railway line, and issue early warning information to trains traveling on lines with environmental risks according to the specific conditions of the line, so as to reasonably control the running speed of trains and prevent Before it happen...

AI Technical Summary

Problems solved by technology

[0004] The construction of disaster prevention systems for foreign high-speed railways adopts a central control model. 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 has exposed the shortcomings of the current high-speed railway disaster prevention system, which cannot monitor the entire line and has low monitoring accuracy, although its structure is complex.

At the same time, the existing disaster prevention system only observes and collects rainfall safety data, and then controls the speed of trains by directly comparing with foreign environmental risk thresholds. There is no corresponding line rainfall safety assessment and prediction system, with certain subjectivity
