Wind direction division-based railway crosswind early warning system and crosswind strength calculation method

Abstract

The invention discloses a wind direction division-based railway crosswind early warning system and a crosswind strength calculation method. The system includes a data collection unit, a quality control unit, a detection unit, and an alarm unit. The data collection unit collects wind speed and direction data. A positioning module obtains a geographic position of a current station and invokes a topographic feature database, and then sends data to the data quality control unit. The data quality control unit compares and analyzes the data with a numerical interval of a meteorological element thathas appeared in history of the station and meteorological data of a neighboring station, and deletes invalid data and corrects erroneous data, and data calculated by the data quality control unit is finally transmitted to the detection unit and compared with a preset threshold. Finally, a control instruction is delivered to the alarm unit. The system provided in the invention can assist in surveying and mapping meteorological history data and improve a crosswind early warning capability and accuracy rate.

Description

technical field [0001] The invention belongs to transportation meteorological measurement and early warning, in particular to a railway cross wind early warning system based on wind direction decomposition and a cross wind intensity calculation method. Background technique [0002] In recent years, with the rapid growth of the national economy, the transportation industry plays an important role in it, and the railway transportation industry, which is the lifeline of the national economy, has developed rapidly. In order to construct the basic route map of high-speed railway of "five vertical, six horizontal and eight lines", my country's high-speed railway has also been developed rapidly. It is under the background of the rapid development of high-speed railway that the research on high-speed railway safety becomes more and more important. [0003] Along the high-speed railway, it is inevitable to pass through some areas with complex terrain and harsh natural environment, a...

Problems solved by technology

However, when the train passes by at high speed, the wind characteristics along the railway will become extremely complex and change drastically, and the strong wind parallel to the direction of the train in the ambient wind is very fast but has little effect on the train, but it is easy to misreport
