【摘要】：高速铁路是我国现代交通的重要组成部分，安全运行是高速铁路的首要问题。研究检测铁路沿线的气象条件、特别是风速问题对高铁的安全运行尤为重要。论文比对研究了国内铁路沿线气象预警系统系统与国外的各类系统，针对新疆北线高铁的实际情况，，补强试验设计了针对性的风数据监测预警系统主要部分。论文的主要内容有： 1.设计了以网络控制和数据采集为核心的风数据采集系统，并完成相关硬件的配建。 2.开发了基于TCP/IP主协议下的自定义网络传输协议，并完成了对所传输数据的相关加密。 3．设计了风数据监测预警系统的多数据库架构，并以数据库数据为基础，完成了相关预警条件的内置算法与预警程序的开发。 4．以三层结构为基础，实现了监测预警系统WEB网站的数据库调用、数据查询与相关数据曲线绘制。本风监测预警系统主要特点： 1.系统用三个采集器同时采集一个采集点的相关数据并以双路传输形式传输，最大限度的保证了数据传输过程中的完整性。 2.利用独立开发的基于TCP/IP协议的自定义网络传输协议传输采集数据，确保在传输过程中数据不被泄露，既保证了列车运行的安全需求，又提高了监测数据的安全稳定性和保密性。 3．WEB网站采用三层结构架设，使各层结构的相对独立，确保数据调用时的安全性。 4.相较于过去的文档数据显示，本系统WEB前台数据以曲线图形式显示，使工作人员能够更加直观具象的对数据进行观测。
[Abstract]:High-speed railway is an important part of modern transportation in China, and safe operation is the primary problem of high-speed railway. It is very important for the safe operation of high-speed railway to study the meteorological conditions along the railway, especially the problem of wind speed. In this paper, the meteorological early warning system along the railway line at home and abroad is compared and studied. Aiming at the actual situation of high-speed railway in Xinjiang, the main part of the wind data monitoring and warning system is designed by reinforcement test. The main contents of this paper are as follows: 1. The wind data acquisition system based on network control and data acquisition is designed, and the related hardware is built. 2. A custom network transport protocol based on TCP/IP master protocol is developed, and the related encryption of the transmitted data is completed. 3. The multi-database architecture of wind data monitoring and warning system is designed. Based on the database data, the built-in algorithm and early warning program are developed. 4. Based on the three-layer structure, the database call, data query and curve drawing of the monitoring and warning system WEB website are realized. The main features of this wind monitoring and early warning system are as follows: 1. The system uses three collectors to collect the relevant data of a collection point and transmit the data in the form of double transmission, which ensures the integrity of the data transmission process to the maximum extent. 2. The self-defined network transmission protocol based on TCP/IP protocol is developed independently to transmit and collect data to ensure that the data will not be leaked during the transmission process, which ensures the security requirements of train operation. It also improves the security, stability and confidentiality of monitoring data. 3.WEB website is set up with three-layer structure, which makes each layer structure relatively independent and ensures the security of data transfer. 4. Compared with the previous document data display, the WEB foreground data of this system is displayed in the form of graph, which enables the staff to observe the data more intuitively and concretely.
