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

Abstract

The invention provides a thunder and lightning information collection and early warning system for a high speed railway. The system comprises a thunder and lightning information collection device, a current signal / value signal conversion device, a device for dynamically generating a reference threshold of thunder and lightning disaster risks, a determining device startd by an early warning program, a locating device, a train controlling device for controlling the speed of a train, a storage device and a control device. A control module serves as a core of the whole system, controls operation of the devices on one hand, and is used for being connected with external devices including an external computer device and the like to achieve communication and control. In the system, the dynamic generating mode is adopted in the reference threshold for evaluating the thunder and lightning disaster risks, the historical disaster situations are combined, and the historical situations are continuously updated after new early warning is given, so that the risk pre-evaluation of a certain region is considered more completely and scientifically with contrast to historical data. The invention further provides a thunder and lightning information collection 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 lightning 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, lightning is a natural environmental disaster with high frequency and great harm. Therefore, effective acquisition of lightning information and reasonable assessment of the degree of lightning disaster can provide 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 characte...

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.
