Embodiment Construction

[0044] In order to further illustrate the technical solution disclosed in the present invention, further elaboration will be made below in conjunction with the drawings and specific embodiments of the description.

[0045] The present invention provides a railway traffic crosswind early warning system based on data quality control, which includes a data acquisition unit, a data quality control unit, a detection unit and an alarm unit, collects wind speed and wind direction data, and obtains the geographical location and position of the station through positioning. The topographic element information calls the national 1:50,000 topographic element database, and then sends the data to the data quality control unit, which is used to check whether the meteorological element records exceed the maximum and minimum values ​​of the meteorological elements that have appeared in the station's history , and delete the invalid data and correct the wrong data, the data calculated by the dat...

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...
