【Abstract】 Concerning the problems of long manual downloading time of on-board data of HXD_2B electric locomotive and high harmfulness of key faults that can not be located quickly, a set of solution was proposed for HXD_2B locomotive intelligent operation and maintenance system based on 5G Application technology. By the self-developed World FIP fieldbus network on-board data acquisition transmission device for carrier, combined with the current advanced 4G APN security transmission technology, 5G fixed-point dump technology and Cloud platform, using the authorized locomotive World FIP network data flow analysis protocol, the system realized the functions of remote operation status monitoring, fixed-point high-speed dump of multi-source data recording files and fault diagnosis and analysis of HXD_2B locomotive, It provided efficient information means and big data platform support basis for locomotive application department. Field application resulted confirm that the system can improve the efficiency of data transfer and fault analysis of locomotive TCMs, AT1 and 6A video, and can meet the needs of intelligent operation and maintenance and field work.更多还原
