列车车地无线多链路并行传输系统研究

Research on Wireless Multipath Train-ground Parallel Transmission System

列车车载系统记录的大量视频和数据信息,对评估列车行驶状态和人员操作规范性具有重要意义,是列车安全行车的重要保障。然而,目前的车地数据转储手段单一,无法满足铁路信息化时代大数据传输和存储的需求。文章提出了一种基于无线多链路的列车车地并行传输方法,并在机务段进行了实际测试部署。测试结果表明,系统达到了车地高速数据转储的效果,满足了快速、自动化大数据转储的需求。该方案有助于预防各类事故的发生,保证行车的安全行和可靠性。

Large amount of video and process data recorded by onboard system is of great significance for evaluation of train running state and personnel operation,and is an important guarantee for safe running of trains.However,current train-ground data backup schemes are unable to meet the demands of big data transmission in the information era.This paper presented a method for train-ground parallel transmission through multiple wireless links,and conducted actual test deployment in a locomotive depot.Test results show that the system with the proposed method achieves high throughput of train-ground transmission and meets the requirements of fast and automatic data dump.The program helps prevent various accidents and guarantees safe and reliable driving.
