摘要
高速铁路进站后与站台之间数据传输会耗费大量时间,利用近场光通信技术可大大缩减传输时间。通过分析高铁停靠位置误差所需的传输覆盖范围,提出了基于近场光通信的高铁大数据传输方案设计,并完成了样机的研制和数据传输实验。实验结果证明:该技术可以在宽松的位置内,实现车地天线之间的自动对准,完成万兆高速数据传输。
Data transfer between the station of high-speed railway and platform will take a lot of time, but transmission time can be greatly reduced by using light near field communication. By analyzing the transmission coverage required the error of parking position of high-speed railway, and puts forward high-speed railway big data transmission based on light near field communication, and the principle prototype and the experiment of data transmission has been completed. Experiments show that the technology enables automatic alignment of transmission modules between two platforms in loose position, completing the transmission of 10 Gigabit ethernet.
