Embodiment Construction

[0026] Such as figure 1 As shown, the proposed method for optimizing the layout of the similarity measurement layout of the wind measurement stations along the railway in this embodiment uses the analysis of the embodiment of the layout of the wind measurement stations along a certain section of the Beijing-Shanghai high-speed railway to further illustrate the present invention:

[0027] Step 1: Collect instantaneous wind speed data from 43 ground meteorological stations within 90km along the high-speed rail line, and pass the collected data through three preliminary quality control marks of climate extreme value inspection, time consistency inspection and continuity inspection, and remove coarse wind speed data. error. The specific selected wind speed data is the 5-min instantaneous wind speed data of 43 ground weather stations in 2018;

[0028] Step 2: Arrange equidistant simulation stations along this section of the railway according to one wind measurement station every 1...

Abstract

The invention discloses a method for optimizing layout of wind measurement stations along a high-speed rail, which comprises the following steps of: selecting wind speed data of meteorological stations within a certain range along the high-speed rail, carrying out preliminary quality control on the wind speed data as a data source, and simulating wind speed data of wind measurement stations at equal intervals along the high-speed rail through Kriging interpolation; taking the simulated stations as existing wind measurement stations along the rail, dividing the rail along the railway into a plurality of area sections according to the landforms of the wind measurement stations, finally increasing and decreasing the wind measurement stations through an improved similarity function, and improving equal-interval station distribution of the wind measurement stations into non-uniform station distribution. Therefore, the wind speed characteristics of each area can be accurately monitored with the minimum number of stations. According to the invention, cost can be saved, and the wind speed characteristics along the line can be accurately monitored.

Description

technical field [0001] The invention relates to the technical field of high-speed rail layout optimization, in particular to a method for optimizing the layout of wind measuring stations along the high-speed rail. Background technique [0002] In recent years, due to the rapid improvement of the national economy and the rapid development of railway transportation and other transportation networks, my country has become the world's largest high-speed railway country, so the requirements for the safe operation of railways are getting higher and higher. The speed of high-speed trains is fast, and the casualties are heavy in the event of an accident. In order to ensure the safety of train operation to the greatest extent, the railway department has set up meteorological observation stations along the railway. Among the various meteorological elements, strong wind is one of the main meteorological disasters affecting the safe operation of railways. [0003] At present, the layou...
