中国机车远程监测与诊断系统(CMD系统)无线转储的WLAN技术应用

Application of WLAN Technology for Wireless Dumping of China Locomotive Remote Monitoring and Diagnosis System(CMD System)

按照中国机车远程监控与诊断系统(CMD系统)规划,机车入段整备、检修时应能够接入站场WLAN无线局域网,以完成行车过程数据的自动下载,且相关数据能够进入站段服务器长期保留,作为铁路信息化大数据应用的基础。从传统机务段实际需求出发,以西安机务段WLAN无线转储建设为例,介绍CMD系统无线转储的WLAN技术应用。

According to the planning of China Locomotive Remote Monitoring and Diagnosis System （CMD system）, the locomotive shall be able to get access to the WLAN of the station yard and automatically upload the data during operation when entering the depot for servicing and maintenance, and the data shall be able to be stored for a long term on the servers of the station and depot to serve as the basis of the application of railway big data. This paper bases itself on the particular needs of traditional locomotive depots, takes the construction of WLAN wireless dumping system Xi＇an Locomotive Depot as an example and introduces the application of WLAN technology in wireless dumping of the CMD system.
