Problems solved by technology

[0004] The construction of the disaster prevention system of foreign rail transit adopts the mode of central control. Usually, the light rail route has a large span, in consideration of data communication and project cost. Environmental monitoring exposed the shortcomings of the current light rail disaster prevention system, which is unable to monitor the entire line and has low monitoring accuracy, although its structure is complex
At the same time, the existing disaster prevention system is more aimed at high-speed railways, and is not very adaptable to light rails

Abstract

The invention provides a light rail cross wind information collecting and early warning system comprising a device for collecting cross wind information, a device for converting current signals/numerical signals, a device for generating a dynamic cross wind disaster risk reference threshold, a device for controlling train speed, a storage device and a control device. A control module serves as a core of the whole system, on the one hand, controls the operation of each device above, and on the other hand, is used for being connected with an external device such as an external computer device toachieve communication and control. In the light rail cross wind information collecting and early warning system, the reference threshold for cross wind disaster risk assessment is generated dynamically; by combination with the historical disaster occurrence situation, the historical situation is updated continuously after the latest warning occurs, so that a comparison is made with historical data, and thus the risk assessment of a region is considered more perfectly and scientifically. The invention also provides a light rail train cross wind information collecting and early warning method.

Description

technical field [0001] The invention relates to the technical field of early warning of light rail railway environmental disasters, in particular to a method and system for collecting and early warning of light rail cross wind information. Background technique [0002] Safety is the foundation of rail transportation. Light rail trains run fast, have a large passenger capacity, and are used as urban rail transit, so higher requirements are put forward for the safety guarantee system. Among the environmental disasters affecting the safe operation of light rail, cross wind 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 light rail trains. [0003] At present, the domestic and foreign researches on light rail security technology present a variety of characteristics, but the overall...
