和谐型机车6A系统视频数据无线高速转储系统研究

Research on Wireless High-speed Dump System of Video Data in 6A System of Harmony Locomotive

剖析了当前和谐型机车6A系统数据转储方式存在的问题,并尝试利用IEEE 802.11ac协议的WIFI技术构建适用于6A系统视频数据的转储方案。在HXD_(1D)车的实车无线下载测试中,此方案平均下载速率接近100Mb/s,且可实现大面积区域覆盖。因此,文中设计的方案可实现6A系统大容量视频数据的无线高速转储,同时也为机车及铁路系统其它行业车载数据的无线转储提供了参考。

This paper analyzes existing problems in the current data dump mode of 6A system of harmony locomotive, and attempts to use the WIFI technology of IEEE 802.11ac protocol to build a dump scheme for video data of 6A system. In the wireless download test of HXD 1D vehicle, the average download rate of this scheme is close to 100 Mb/s, and large area coverage can be achieved. Therefore, the scheme designed in this paper can achieve high-speed wireless transfer of large-capacity video data in the 6A system, and also provides a reference for the wireless transmission of vehicle-mounted data in railway systems.
